Citizen Guide to Lessening Storm Vulnerability ' STORM HAZARD MITIGATION AND POST DISASTER RECONSTRUCTION PLAN SUPPLEMENT 1995 On June 6, 1995 the Planning Board held its first annual exercise of the ' Reconstruction Task Force. Results were in the form of recommendations in two categories. First, policy ' recommendations were made to the Board of Commissioners for prompt consideration and second, additional advise to be incorporated into the plan. These recommendations consider a direct strike from a storm category 3 or stronger. ' Policy recommendations for prompt consideration by the Board of Commissioners and incorporated into the plan: ' 1. Inclusion of an automatic moratorium provision for those structures p t uctures damaged in excess of 50%. ' 2. Work on poli cy cy regarding the meeting place and procedure for re-entry of the ' Reconstruction Task Force. 3. Recommendation that the Reconstruction Task Force should meet with other ' jurisdictions to determine common problems and issues. 4. Adopt a contingency budget for legal expenses. 1 Recommendations to be incorporated into the plan: 1. Investigation of the concept of an emergency CAMA Permit for a drainage ditch or ' canal to remove flood waters. 2. Issue "field permits" for minor damage (general permits) with fees waived for victims ' of storm damage. Develop a sunset clause on fee waiver. 3. Considering destruction of a section of NC 12 and associated utilities, decisions to rezone or replace infrastructure should be made in the general best interest of the community and resistance to future storms. ' 4. Stress emphasis on elevation of pre -FIRM structures built below the base flood. Recommendation of "freeboard" requirements where structures met NFIP ' requirements but receive flooding. Page 2 STORM HAZARD MITIGATION AND POST DISASTER RECONSTRUCTION PLAN SUPPLEMENT 1995 5. Include provision for a reconstruction information center in the plan to disseminate information to those rebuilding including steps to make homes more hurricane resistant. Page 2 6. Consider capitalization on a storm event to bring current Town wastewater system up to date and eliminate point source discharge. 7. Include statement on adoption of a plan for floodproofing water lines in Hurricane Mitigation Plan. 8. Carefully consider replacement of mobile homes destroyed by a storm. (meet new standard). 9. Work on incentives for property owners of structures which are built to resist storm and flood damage. 10. Policy on OBBC WWTF - What steps would the Town take if it was destroyed? Abandoned? 11. Reconstruction Task Force has no role during the storm event and is not needed immediately afterward. However, this group can be helpful as soon as information from damage assessment teams is available which may be before general public re- entry. 12. Damage assessment reports (from the building inspector) should include information beyond requirements of State and Federal Agencies. Information such as still flood water elevations, tide lines, debris lines, and extreme wind damage areas should be reported. This information will assist the Reconstruction Task Force in making reconstruction recommendations. Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 1 r Setting The Town of Kill Devil Hills is located on Bodie Island in Dare County on the coast of eastern North Carolina. The island is part of a barrier island ecosystem of 3,800 total acres. The town covers an area of 6.5 square miles reaching from the Atlantic oceanfront to soundfront. The higher secondary dune line slopes westward to a series of bays, marsh islands, high sand dunes and a mans a forest. Kill Devil Hills has experienced severe northeast- ers, southeast storms, hurricanes and waterspouts in the past. With 1.4 miles at the widest point from sound to sea, the community is vulnerable to hazards from both the east and the west. Kill Devil Hills has evolved from a small village of private residences and secluded beach cottages into a thriving tourist area, with a mixture of motels, restaurants, retailers, real estate companies, vacation rental cottages, condominiums, municipal and county facilities, office buildings, convenience stores, and residential neighborhoods. The economy is based upon tourism, with over 60% of the single-family dwellings owned by non- residents. Many of the older second homes, which are owned by non-resi- dents, are rented to the local work force. The prevalence of absentee property owners and second homes, combined with a general lack of reliable information on insured values of the real estate, ' presents unique problems to hazard mitigation and reconstruction. Also, many homes are rented through rental agencies, making it more difficult to reach property owners directly regarding improvements and safety considerations related to these structures. The Town was incorporated in 1953. With more than 4,400 year-round residents (most recent population 1993), Kill Devil Hills has become the most populated of five incorporated towns in Dare County. It is bordered on the north by the Town of Kitty Hawk, and on the south by the Town of Nags Head. I Town of Kill Devil Hills and Glenn Harbeck Associates 1. Introduction 0 n E 0 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 1. Introduction 1. INTRODUCTION Purpose To help minimize damages and social turmoil after a devastating storm event, the Town of Kill Devil Hills has created this Storm Hazard Mitigation And Post -Disaster Reconstruction Plan... The purpose of the Plan is to establish procedures and actions which can reduce the potential for the loss of life, minimize damage to property and to provide a framework for orderly reconstruction in the event of a hurricane or other natural disaster. Mitigative This hazard mitigation and reconstruction Plan is part of the Kill Devil Objectives of the Hills comprehensive strategy for dealing with the long term Plan consequences of a major storm. More specifically, the prescribed mitigation actions are intended to promote the following primary objectives. Many of these objectives also relate directly to the goals of the National Flood Insurance Program and Community Rating System (CRS): 1. Protect human life and health. 2. Facilitate evacuation. 3. Promote rebuilding and reconstruction in a prompt and orderly manner. 4. Reduce damage to existing and future development. 5. Reduce damage to existing and future public facilities and structures. 6. Minimize expenditure of public and private money for repetitive repairs and reconstruction. 7. Minimize need for emergency actions associated with storm events which are usually undertaken at public expense. 8. Minimize prolonged business interruptions, especially involving businesses which provide critical supplies and services. 9. Assist in maintaining a stable tax base through sound use of land located in storm hazard areas. 10. Lessen exposure of the Town to liability claims. 11. Balance the need to rebuild infrastructure and buildings with the need to preserve and enhance the beaches, dunes and other natural features of the Kill Devil Hills environment. Non -Mitigative In addition to the above -noted primary objectives, there are a number Objectives of the of other beneficial objectives that this Plan helps to achieve, but that Plan do not relate directly to the mitigation of destructive storm effects. For this reason, the following objectives are labeled non -mitigative: ITown of Kill Devil Hills and Glenn HarbeckAssociates Page 1-1 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 1.Introduction I 1. Enhance local recreational and open space opportunities including enhancement of public access to the beach, ocean and sound. 2. Enhance and restore local natural ecosystems. ' 3. Reduce traffic congestion, noise and other transportation generated problems. 4. Enhance the long-term economic vitality of the town. ' 5. Improve efficiency in the delivery of public services. 6. Protect and improve the aesthetic and scenic characteristics of the environment of Kill Devil Hills. ' What This Plan This Plan is not an emergency operations plan (EOP). Such plans Is and What It Is have been prepared by the Town and the County to respond, on a Not short term basis, to crisis situations ranging from hazardous waste spills to major storm events. As the name implies, these plans are ' operational in nature, oftentimes setting emergency procedures for marshaling people and equipment in very rapid order to deal with the immediate needs of those persons affected by the emergency event. This Plan, on the other hand, is long term in nature, setting forth policies and preventive actions which the Town can act upon now to ' help mitigate the destruction caused during a major storm event. In addition, this Plan sets forth post -storm policies and standards to guide reconstruction in a pre -planned, orderly way. Such ' reconstruction may take months or even years to complete, depending upon the severity and ultimate impact of the storm. Why Prepare Unless a suitable plan for reconstruction has been prepared This Plan Now? preceding a disaster, the pressure and urgency to rebuild damaged properties and facilities after the storm may create a pattern of ' construction and land use even more susceptible to destruction than the pre -disaster pattern. Unless a plan exists to correct inappropriate development patterns, reconstruction may be unimaginative and ' lengthy, and provide inadequate relief from future damaging occurrences. ' Two Phases of Hazard mitigation occurs in two distinct phases of disaster Hazard planning— the pre -disaster phase and the post -disaster ' Mitigation reconstruction phase. These two phases may be described as follows: ' Pre -disaster Pre -disaster mitigation involves the identification of public policies mitigation and actions which can be taken today which reduce future disaster impacts, including injury or loss of life, and the extent of damages to , public and private property. The overriding goal is to make new development and redevelopment less susceptible to future disaster Town of Kill Devil Hills and Glenn Harbeck Associates Page 1-2 ' Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 1. Introduction ' damages. Pre -disaster mitigation offers the opportunity to develop policies and programs in the relative calm between storm events — without the duress and pressure that accompany immediate, post - disaster decision -making. Pre -disaster planning also promotes a more rapid and efficient recovery, while at the same time making the ' most of post -disaster opportunities for safety improvements. Post -Disaster Post -Disaster mitigation involves the implementation of policies to ' mitigation guide the reconstruction of the community in a way which seeks to eliminate or reduce those development and building practices which make the community especially susceptible to storm damage. The ' need for post -disaster mitigation is often best understood by the public immediately following a storm event, since the reality of the disaster threat is fresh in people's minds. Following a hurricane or major coastal storm, damage may be widespread. Numerous ' opportunities will be available during reconstruction to promote hazard mitigation, as well as to achieve other local land use objectives. ' Experience in other coastal states and localities hit by hurricanes indicates that reconstruction and rebuilding can occur very quickly ' and that mechanisms must be put into place prior to the storm which will serve to coordinate and manage the reconstruction process. Such a system will insure that significant opportunities for mitigation are not overlooked or.lost in the haste to rebuild, while, at the same time, will facilitate swift reconstruction and recovery for those structures or portions of the community not as heavily damaged. ' Post -disaster mitigation can also be greatly aided by the abundance of technical and financial assistance that is often available following a major storm event. It is important that the mitigation Plan set forth specific policies and actions that position the Town to take advantage of every form of assistance to which the community may be entitled. ' (See Appendices for types of assistance available.) Finally, post -disaster reconstruction, if handled correctly, is actually ' pre -disaster mitigation, in terms of the next event. And there will always be a next event. Summary of The public involvement strategy employed for the Kill Devil Hills ' Public Storm Hazard Mitigation and Post -Disaster Recovery Plan Participation provided several avenues for effective public involvement. First and foremost was the designation of the Planning Board as the Steering ' Committee for the Plan. Planning Board The Planning Board took an active, leadership role throughout the ' Leadership preparation of the Plan. The Board 's role was particularly critical Throughout the during the formulation of the overall policies and implementation Process strategy. In this capacity, the Planning Board offered key Town of Kill Devil Hills and Glenn Harbeck Associates Page 1-3 ' Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 1. Introduction , perspectives, providing input on the accuracy of information gathered, and feedback on the recommendations drafted. All Planning Board meetings were open to the public. ' In addition to the leadership provided by the Planning Board, opportunities were also provided for meaningful involvement in plan formulation by the community at large. Several of these opportunities ' are outlined below: 1. Issue The first major public meeting held for the Plan consisted of a ' Identification and carefully planned and publicized "public forum" to kick off the public Policy Preferences involvement process. The meeting was hosted by the Planning by the Public Board and the Town of Kill Devil Hills. A special announcement was ' prepared for inclusion in the Town Newsletter and other distribution. Announcements were also sent to local news media. The purpose of the public forum was to provide Town residents and property owners ' the opportunity to make their concerns known about development issues involved in storm hazard mitigation and post -disaster recovery. The intent was to accomplish this task as early as possible ' in the planning process, so that these concerns could be recorded and used as a foundation for the preparation of the Plan. The involvement technique used to solicit public input was a specially designed "walk around questionnaire". In preparation for the meeting a set of "straw man" policies were prepared in the form of affirmative statements. Participants were then asked to walk around the room with pencil in hand, registering their level of agreement or disagreement with each potential policy statement. Opportunity was ' also provided to write additional comments about any policy area in space provided on the poster -board -sized questionnaire sheets. All comments, whether favorable, neutral or negative, were noted for the record. (See Appendix 9) ' Immediately following the meeting, the survey results, along with ' comments received, were transferred to smaller, report -sized summary sheets. These sheets were then conveyed to the Planning Board for review and reference during the balance of the planning ' process. The same sheets were also made available for public inspection and review throughout the process. It should be noted that the poster -sized questionnaire sheets , remained on the wall of the Town Meeting chambers throughout the several -month planning process. In this manner, citizens could continue to reflect and comment upon the policies over an extended , period of time. It also allowed some citizens the opportunity to make comments while at the Town complex on other business. t Town of Kill Devil Hills and Glenn Harbeck Associates Page 1-4 1 IStorm Hazard Mitigation and Post -Disaster Reconstruction Plan 1. Introduction Note: The purpose of issue identification and policy preferences by the public was not to establish a legalistic or dogmatic standard for plan development. Rather, it was simply another way to allow the ' public to freely express their concerns about storm hazard mitigation and reconstruction. At the same time, this exercise had a self - educating effect, in that the process allowed area residents and interest groups to exchange information on a broad spectrum of viewpoints. ' 2. Work Sessions of In the weeks and months following the initial Public Forum, the the Planning Board Planning Board held a number of work sessions to develop the Plan, and to consider public comments. Appropriate sections of the Plan ' and policies were then prepared as authorized during these work sessions. Development of a complete draft of the Plan resulted. ' 3. Presentation, Upon delivery of a complete draft Plan, the Planning Board met in Review and several more special and regular public meetings to discuss the Revision of Draft proposed Plan and policies. Final editing and Plan revisions were Plan then prepared as authorized. Summary of The following is a summary of all public meetings held to discuss the ' Meetings development of the Storm Hazard Mitigation and Post -Disaster Recovery Plan.

Hazard Identification and Evaluation Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 2. Hazard Identification and Evaluation 2. HAZARD IDENTIFICATION AND ' EVALUATION Types of Storm There are fundamentally three types of coastal storms that have the ' Events potential for inflicting major damage to the Town of Kill Devil Hills: hurricanes, northeast storms (nor'easters), and tornadoes. Tornadoes are often, but not always, a spin off of major hurricane ' storm systems. Of the three types of storms, the Atlantic hurricane poses the greatest threat for catastrophic destruction over the entire length and breadth of the town. For this reason, the bulk of this Plan ' is designed to be responsive to the type of situation created by a major hurricane event. ' Hurricanes The anatomy of a tropical cyclone or hurricane resembles a large, Described and circular column of clouds with air rotating in a counter -clockwise ' Categorized direction along the storm's periphery to a concentrated center of low pressure. Winds within these storms can exceed 200 miles per hour near the vortex, although storms of this magnitude are rare. Atlantic hurricanes typically originate as tropical waves off the west coast of Africa and in the Caribbean Sea. Hurricanes develop and ' mature by passing through several stages based on wind speed characteristics: Tropical depression: winds of 38 miles per hour or less Tropical storm: winds between 39 and 73 miles per hour Hurricane: winds greater than 73 miles per hour ' Hurricanes, in turn, are categorized by convention into one of five increasingly damaging and more powerful storms. The widely recognized Saffir/Simpson Damage Potential Scale is provided on ' page 11 to more accurately describe each Category of Storm. Probability of While the hurricane season extends from June through November, Storm most recorded hurricane activity along the Carolina coast Occurrence by (approximately 90%) has occurred in August, September and Time of Year October. (See Figure 1) According to information compiled by the and Location Federal Office of Coastal Management, the Outer Banks of North Carolina have an 11 % chance of encountering a direct strike from a ' hurricane in any given year. (Figure 2) This is the highest percentage probability of any coastal segment on the east coast of the United States north of "hurricane alley" in south Florida.

Hazard Identification and Evaluation Predicting Hurricanes typically follow a parabolic path, with a westward forward Landfall movement of about 12-15 miles per hour. Both the direction and ' forward speed of the storm can vary dramatically once entering the Atlantic basin. Predicting the path and travel time of a hurricane has traditionally been a difficult and complicated problem for weather ' forecasters. Insufficient documentation recorded from previous storms, as well as unpredictable upper -level wind patterns that steer the storm, make accurate predictions difficult at best. A hurricane "normal" ' moving on a parabolic path may stop dead in its track, reverse direction, or take a sharp turn, all in response to changes in atmospheric currents. (See diagram below) 1 r, Track of Hurricane Ginger,1971 111 •� 17 s6 -- 1_-- w � Neumann, et al, Tropical Cyclones of the North Atlantic Ocean, 1871-1980, Asheville, NC: National Climatic Center. 1981 In recent years, however, the unpredictability of hurricanes has been reduced somewhat through the use of improved forecasting tools such as satellite imagery, decision arcs and the hurricane watch/warning system. These tools, combined with an enhanced communication network between weather related agencies and local governments, have improved the ability of involved officials to respond effectively to major storms and greatly diminish the potential for loss of life. I Town of Kill Devil Hills and Glenn Harbeck Associates Page 2-3 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 2. Hazard Identification and Evaluation I Damaging Hurricane intensity, as determined in general terms by the Forces and Saffir/Simpson Scale (see next page), is directly related to the Storm Elements severity of storm forces and elements that cause fatalities and property damage. These elements include wind and flood damage, wave action and erosion. The effects of each of these forces are outlined in some detail in the supplemental report to this document, entitled: Identification and Evaluation of Storm Hazards Threatenina the Town of Kill Devil Hills. NC by William C. Schmidt. In the report, Schmidt discusses these forces as particularly applicable to the Outer Banks of North Carolina. Historical Storm As noted previously, coastal North Carolina is one of the more Activity for hurricane vulnerable locations along the eastern coastline of the Coastal North United States. Since 1886, some 50 hurricanes have directly Carolina affected eastern North Carolina. Coastal North Carolinians' experiences with hurricanes date back to the earliest settlers. Since 1899, North Carolina has received direct hits from 22 hurricanes, eight of them classified as "major" (a 3, 4, or 5) on the Saffir/ Simpson Scale. These "direct hits" are cases where the center of the storm passed directly over the North Carolina coast. The state has also suffered damages from numerous hurricanes whose centers came through South Carolina or stayed at sea, passing close to the North Carolina coast. With the exception of very localized damages related to Hurricane Diana in 1984, and heavier localized damages from Hurricane Emily in 1993, coastal North Carolina has not experienced major damage from a hurricane in over 20 years. Even the few storms of the 1960's and 70's were relatively "mild", causing mainly crop damage and erosion, with little or no loss of life. This long period of relative inactivity is in marked contrast to the hurricanes which devastated North Carolina in the mid-1950s. Between August 1953 and September 1955, seven hurricanes, four of them (Hazel, Connie, Diane, and lone) classified as major storms, rocked the Carolina coast. Damage from these storms was estimated to be in excess of 300 million dollars (1955 dollars). It is important to emphasize that the extensive development of the last several decades has left coastal North Carolina vulnerable to damages of monumental proportions today.

ITown of Kill Devil Hills and Glenn Harbeck Associates Page 2-5 7 ' Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 2. Hazard Identification and Evaluation ' Historical Storm Due to its location on the Outer Banks, the Town of Kill Devil Hills is Activity for Kill particularly vulnerable to major storms. Two of the first documented Devil Hills and major storms encountered were the two hurricanes of 1933. These ' the Outer Banks two storms destroyed sections of the beach road (NC 12)— which had just been completed in 1932. In 1939, the Great New England Storm caused considerable overwash with little damage. In 1944, a ' hurricane wiped out several soundside cottages in Virginia Dare Shores, including a soundside pier with a dance hall and cafeteria at West Hayman Boulevard. Hurricane "Donna" hit in 1960, coming from the east with flooding and causing considerable damage when ' winds shifted to the west. The Holiday Marina was destroyed by "Donna" with significant soundside flooding to the Avalon Beach area at the northern end of Town. ' On March 7, 1962 a powerful northeaster (See Section 8 for description of northeaster storms) hit the Outer Banks of North ' Carolina and was later dubbed "The Ash Wednesday Storm." This mighty meteorological phenomenon, unlike a hurricane, pounded Kill Devil Hills for two and a half days with heavy rains and damaging ' winds. Although the Town's population at the time was only 150 to 200 residents, many people were caught by surprise and found themselves waking up on Wednesday morning with water in their ' homes and, in some cases, saw their homes floating away. Kill Devil Hills was almost totally inundated while homes, hotels, businesses, piers, and roads were either partially or totally destroyed. Fortunately, ' no lives were lost on the Outer Banks despite the thousands who were left stranded and homeless. By the time the storm moved out to sea, it had rocked the entire Mid -Atlantic coast, destroying about ' 1,800 dwellings with a total structural loss in excess of $234 million over the approximately 500 miles of coastline affected. "Grace" In late October 1991, the remnants of Hurricane (now referred to as the Halloween Storm) positioned itself off the coast of North Carolina. By October 31, 1991, Kill Devil Hills was experiencing ocean overwash at every high tide. Although the sun ' was out and winds were calm, considerable flood waters affected many properties as tides washed to US 158. In Kitty Hawk, just north of Kill Devil Hills, US 158 was covered by 18 inches to three feet of , water at high tide. On March 13, 1993, the Town experienced "the storm of the century"* , which pummeled soundside residents with near hurricane force winds for over 12 hours causing flooding and debris removal for over a month after this event. ' problems 'Note: Storms are often inaccurately referred to as, for example, the "worst ever" based on dollar damage or personal suffering. However, to accurately gauge the severity of one storm relative to another, it is better to use storm characteristics based on scientific data such as ' barometric pressure, high tides, storm surge, wind speeds, and other meteorological factors, rather than structural losses or human distress. Town of Kill Devil Hills and Glenn Harbeck Associates Page 2-6 IStorm Hazard Mitigation and Post -Disaster Reconstruction Plan 2. Hazard Identification and Evaluation Hazard Areas The following paragraphs describe how the various hazard areas And Properties designated on the Kill Devil Hills Hazard Areas Map (inside back ' At Risk— cover) were determined. The map is based upon a hazardous areas Localized To Kill land classification system to help determine relative degrees of risk ' Devil Hills associated with various locations in the community. As will be seen below, the system employs a number of factors relating to the characteristics of a strong Category III hurricane (130 mph sustained ' winds, 9-12 foot storm surge) and an average tide (no lunar tide). 1. Extreme Hazard HAZARDS: flooding, wave action, erosion, floating & wind -driven Area debris, powerful winds. ' A geographical area labeled "extreme" represents the most dangerous location in terms of the potential for both life and property ' dosses. These areas have little, if any, vegetation and are often at or just slightly above mean sea level. Also, erosion and direct exposure to both ocean and sound waterfronts increase the element of risk. Il. High Hazard HAZARDS: flooding, damaging wind wind -driven debris. Area ' The difference between the "high hazard" area and the "extreme hazard" area is chiefly a function of proximity to the waterfront and base flood elevation. In other words, high hazard areas are further ' removed from the effects of ocean front and sound front wave action and tend to have somewhat higher elevations. Vegetation is often more pronounced and provides some protection from flying debris. ' Ill. Moderate HAZARDS: damaging winds, wind -driven debris, possible flooding at Hazard Area lower elevations. ' The "moderate" risk zone offers protection such as good elevation (above the 500 year flood) and good vegetative cover in places. Thus, this area is more resistant to flooding, and with good vegetative ' cover, provides for better resistance to storm forces. IV. Limited Hazard HAZARDS: strong winds. ' area The "limited hazard" area represents the least dangerous* of all geographic locations in Kill Devil Hills. As the Hazard Areas Map ' indicates, the maritime forest is found within this zone. This area enjoys all the natural defenses including good elevation, removal from wave action, and substantial vegetation. However, under certain ' conditions, downed trees may be hazardous to property and power lines and obstruct recovery. ' *Note the use of the words "least dangerous" rather than "safest , all parts of Kill Devil Hills would be on dangerous ground in the event of a direct hit by a major hurricane. ' Town of Kill Devil Hills and Glenn Harbeck Associates Page Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 2. Hazard Identification and Evaluation Hazard Area The following methodology explaining Summary A is based on total Structure Value tax value of all structures as of March, 1994. Figures do not include value of water lines, power lines, telephone lines, etc. Specific figures were provided by the Dare County Tax Office for the extreme risk area. The moderate risk area was computed by counting the number of residences and businesses and then multiplying these numbers by the average value of each category of structure. For instance, if the average cost of a gas station is $182,970 and eight gas stations were counted, then the total structure value is $1,463,760. Similarly, the limited risk category was reckoned by counting the number of structures in the limited hazard area and then multiplying this figure by the average value. of a home in Kill Devil Hills (Approximately $85,000). Finally, the high risk category was figured by adding all the structure values in all the other categories (extreme, moderate, limited) and then subtracting this value from the total structure value. The final result is a good estimate of how much structural value would be threatened in the event of a direct hit from a strong Category III storm. SUMMARY A: Value of Structures by Mapped Risk Areas Kill Devil Hills Total Structure Value (3/94) $377,577,000. Structure Value in extreme risk areas $105,543,230. (Properly at extreme risk = 28% of structure value) Structure Value in high risk areas $114,768,448. (Property at high risk = 30.4% of structure value) Structure value in moderate risk areas $156,500,922. (Property at moderate risk = 41.4% of structure value) Structure Value in limited risk areas $765,000. (Property at limited risk = 0.2% of structure value) 0 Note: Please refer to the Haza d Area MM to locate the individual risk zones i.e. extreme, I high, moderate, limited.

Pre -Storm Hazard Mitigation J 1 0 H 3. PRE -STORM HAZARD MITIGATION Introduction Reducing the risk of fatalities and property damage from hurricanes and other natural disasters is a primary goal of local government planning and growth management. Pre -storm mitigation falls under the local government's responsibility to protect the public health, safety, and general welfare. Pre -storm hazard mitigation can be implemented in large measure through the diligent and consistent enforcement of existing development standards and regulations. At the same time, it is important that the Town continually seek to improve upon its development standards and regulations for changes which might reduce damages in the event of a major storm. While some standards and regulations, such as the State Building Code are established and maintained by authorities beyond the Town's control, other standards such as zoning and subdivision regulations, are subject to considerable local discretion (to the extent allowed by the State Enabling statutes). These are the standards where the Town has some latitude to implement development standards especially tailored to the unique needs of the community. Existing The following section provides a brief summary of existing Development regulations, both State and local, with specific attention given to pre - Policies, storm mitigative measures. On -going evaluation of the merits and Standards and feasibility -of the changes to local standards and regulations would be Regulations a responsibility of the Hazard Mitigation/ Post -Disaster Reconstruction Task Force. (See Section 4.) 1. Flood Damage Chapter 8 of the Kill Devil Hills Town Code provides construction Prevention guidelines to help reduce and/or prevent the damage that storms can Ordinance of the have on various structures located within the Town's jurisdictional Kill Devil Hills Town boundaries. The purpose of such guidelines is quite clear: to help Code (Ch. 8. prevent the loss of life and property by establishing provisions that adopted March 8, serve to make development and growth more resistant to natural 1993) hazards. This chapter attempts to achieve that purpose in the following ways: First, development permits must contain certain information prior to approval, such as first -floor elevations and flood proofing. Secondly, should a variance be requested, certain criteria must be met, such as the susceptibility of the proposed structure to flooding and the protection of life and property. Thirdly, this chapter spells out several measures that can be taken to reduce flood hazards including the anchoring of structures and the use of flood -resistant construction materials. Chapter 8 also provides several provisions concerning special types of structures and land uses and how development Town of Kill Devil Hills and Glenn Harbeck Associates Page 3-1 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 3. Pre -Storm Hazard Mitigation ' should proceed to mitigate possible storm damage. Included in this section are guidelines for residential construction, non-residential construction, manufactured homes, recreational vehicles, elevated ' buildings, temporary structures, accessory structures, and structures located within floodways, V zones and subdivisions. Finally, the penalty for violating any component of the ordinance is $50.00 ' and/or 30 days imprisonment for each day of non-compliance. (For more information, a copy of the Town's Flood Damage Prevention Ordinance is included as Appendix 1 to this report.) I 2. North Carolina The development standards of the Coastal Area Management Act Department of are probably the most "visible" regulations promulgated to ' Environment, encourage wise development and to help reduce storm damage. The Health and Natural Division of Coastal Management (DCM), in partnership with local Resources— governments, administers these standards, usually for developments , Coastal Area located in one of several types of Areas of Environmental Concern Management Act Development (AEC's). ' Standards A primary example of an area demanding special treatment is the Ocean Hazard AEC. Development in these areas deserves special attention due to the potential impact of waves, erosion, and powerful ' winds. For development in an Ocean Hazard AEC, the North Carolina Department of Health, Environment, and Natural Resources (NC DEHNR) has created special development standards to help ' reduce or prevent death, injury, and the destruction of property resulting from natural hazards. Some permit requirements relate to the placement of the lot in relation to frontal and primary dunes, ' oceanfront setbacks, vegetation disturbance and many others. Piling size, depth, and strength criteria are also clearly established by these standards. ' Not all types of development in an AEC require a special permit. Examples of development types which may be exempt from the , Coastal Area Management Act (CAMA) permit requirements include certain small ditches and access -ways over frontal dunes, provided they meet certain width and building code requirements, and do not alter the integrity of the frontal dunes. Also; single-family residences ' located within the Estuarine Shoreline Area of Environmental Concern (AEC) may be exempt from CAMA permits if a 40 foot buffer area is maintained between the location of construction and the , normal water level of the shoreline, among other requirements. NC DEHNR also exempts from the CAMA Minor Development Permit requirement certain accessory uses as well as the maintenance, ' repair, and replacement of structures or parts thereof, provided certain conditions are met (such as slope and disturbed area requirements) ' Town of Kill Devil Hills and Glenn Harbeck Associates Page 3-2 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 3. Pre -Storm Hazard Mitigation P Finally, for lots platted prior to June 1, 1979, that cannot be developed due to strict oceanfront setback requirements, exceptions can be made for single-family residential construction in the Ocean Hazard AEC. However, several conditions must be met including meeting the maximum setback possible, piling standards, frontal dune requirements, and lot coverage provisions. Appropriate sections of the NC DEHNR Coastal Management standards are provided as Appendix 2 to this Plan. There the reader will find additional information, definitions, and restrictions concerning construction in estuarine and ocean hazard areas. It should be remembered that these are state guidelines; local governments may have additional provisions regarding development in these sensitive, natural environments. 3. Chapter2l. Article 6, Section 21-6.1, paragraph D of the Kill Devil Hills Town Article 6 of the Kill Code, outlines requirements for non -conforming structures and their Devil Hills Zoning non -conforming uses as they relate to natural disasters. A key Ordinance - Non- provision of this section covers the circumstances under which a conformities. damaged structure may be rebuilt: September 13, 1993 Should a nonconformity suffer extensive damage from a natural disaster, the structure may be rebuilt to 100% of its previous use provided the damage occurred within 30 years beginning November 18, 1991. Should the damage happen more than 30 years after November 18, 1991, the structure or use thereof, must be rebuilt in conformity with applicable zoning ordinances. If damage occurs within the 30-year provision, non -conforming uses may not be restricted in the following areas: total space utilized, height limitations, setbacks, density requirements and lot coverage. In any case, non -conformities must not be increased and every effort must be made to decrease the nonconformity. Other issues relating to non -conformities in Chapter 21 include non- conforming land uses, non -conforming signs, changes of tenancy or ownership, and maintenance. Bringing a structure and its use in conformity with the zoning ordinance is just one more step that can be taken to help mitigate potential damage resulting from a major storm event. (For more information about how non -conformities are handled, a copy of Article 6 of Town Zoning Ordinance —Non - conformities, is included as Appendix 3 to this report.) 4. North Carolina The State Building Code is perhaps one of the most important set of State Building standards that a business or homeowner can follow to strengthen the Code -1993 integrity of his/her structure to help withstand the forces of a storm. Provisions in the Code apply to new construction and certain modifications to existing buildings. Some mandates in the Code for Town of Kill Devil Hills and Glenn Harbeck Associates Page 3-3 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 3. Pre -Storm Hazard Mitigation I coastal residential construction include, for example, the following: piling standards (sizes, depths, spacing), construction materials, construction methods (e.g. stud spacing, use of fasteners), roof coverings and insulation. Construction standards in Coastal High Hazard Areas (e.g. Ocean Hazard AEC's) are more stringent than for locations away from the ocean. The NC Building Code also includes a detailed description of how structures can be strengthened as a pre -storm mitigative measure. (For more information, please see Chapter 27 of the State Building Code, Coastal and Floodplain Construction Standards, included as Appendix 4 to this report.) 5. 1993 Land Use Chapter 4, Section F.2 of the 1993 Kill Devil Hills Land Use Plan, Plan Update for Kill addresses storm hazard mitigation in general terms. Types of Devil Hills hazards likely to be experienced in the Town are outlined, including flooding, erosion, high winds, tornadoes, and the less -threatening snow and ice storms. The Plan notes that the degree of potential damage caused by such hazards will vary according to location, particularly regarding flooding and wind damage.. The Plan goes on to mention why Kill Devil Hills is so vulnerable, where development has taken place, and the likely direction in which future development may move. Further, the Plan states that certain controls are in place to ensure maximum resistance to natural hazards such as a flood damage prevention ordinance, building codes, a zoning ordinance as well as various state and federal regulations. Again, these tools are in place to protect the general health, safety, and welfare of the public as well as to minimize structural damage to the community. (Refer to Appendix 5 for further information.) 6. Stormwater Section 21-7.1 of Article 7 of the Town's Zoning Ordinance contains Management in Kill certain provisions for the management of stormwater on and off Devil Hills properties. Stormwater management is essential in mitigating property damage from flooding as well as contributing to a reduction in maintenance and capital expenditures for stormwater drainage systems. Not only must all properties have a system to handle surface water runoff equal to the amount of water expected to result from the ten-year, two-hour event (approximately 4.2" of water), but every reasonable effort must be made to retain as much of the stormwater as possible on the site. Furthermore, no surface water shall be directed into a septic tank system. Runoff must be directed into acceptable sources such as swales, ditches, ponds, or other drainage systems. Also, this section discusses what information regarding drainage must be included in the development plans. Some examples include the flow direction of stormwater, estimated amount of runoff, and certain dimensions of drainage system components such as size, shape, and invert measurements of culverts. Natural and man-made Town of Kill Devil Hills and Glenn Harbeck Associates Page 3-4 ' 1 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 3. Pre -Storm Hazard Mitigation ' watercourses must remain unobstructed to allow for the free flow of water so as to help prevent clogging. For instance, weeds, logs, and ' debris are very effective in contributing to ditches and other channels becoming choked from sediment. ' Other issues discussed in this section include maintenance responsibilities of systems, various handbooks and formulas used to design systems, among other requirements. Again, the above is simply a summary. Refer to Article 7 of the Zoning Ordinance for ' more information. Importantly, property flooding can be costly and dangerous. Thus, effective and efficient drainage of water from storms is crucial in relieving the potentially damaging impacts of ' torrential rains. 7. Soil Erosion & Soil Erosion & Sedimentation Control Article 7 also contains rules ' Sedimentation for Soil Erosion and Sedimentation Controls. Whenever land is Control in Kill Devil disturbed for construction, there exists the opportunity for increased Hills surface water runoff and accompanying increased erosion and sediment flow. When soil particles become dislodged and begin to move downslope in extraordinary amounts, watercourse and drainage systems can become clogged and negative impacts on ' water quality can result. Therefore, controls and regulations are necessary to ensure against such adverse events. ' Section 21-7.2 of Article 7 of the Kill Devil Hills Zoning Ordinance governing soil erosion and sedimentation controls states that approval of a soil erosion control plan will be required for all land disturbing activities greater than one-half acre. Additionally, land disturbing activities not exceeding 5,500 square feet in surface area will not require a land disturbing permit from the Town. What follows ' is an outline of the issues and concerns covered in this section: First, not all areas must obtain a land disturbing permit, such as certain agricultural and forest lands. Also, some activities may not need a permit, such as fire fighting and the stock piling of gravel. Second, the required erosion control plan (which must be approved ' and filed by the Town at least 30 days prior to initiating the activity) must contain certain information regarding critical areas, time and limit of exposure, surface water and sedimentation controls, to name ' a few. Also, buffer zones may be required depending on proximity to a lake or other natural watercourse. Standards concerning the angle of graded slopes and fills and the vegetation thereof are set forth in ' this section. Additionally, HQW (high quality water) zones are given special treatment with different standards than those of other areas. ' Third, stormwater outlet protection, innovative techniques for minimizing erosion, maximum permissible velocities for discharge, borrow and waste areas, access and haul roads, along with ITown of Kill Devil Hills and Glenn Harbeck Associates Page 3-5 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 3. Pre -Storm Hazard Mitigation I operations conducted on or in lakes or other natural watercourses ' are discussed. Information is provided relating to the erosion and sedimentation plan itself such as the number of copies needed, time ' frames, who needs copies, and plan content. Fourth, reasons for an erosion control plan being disapproved are given such as an applicant having a history of failing to comply with ' approved plans within the time periods specified. Steps necessary to change erosion plans or to appeal disapprovals are clearly explained. This section also articulates the right of the Town to ' periodically inspect sites for conformance to state and local ordinances and approved plans and to impose penalties or shut down operations should any violations occur. Clearly, erosion and , sedimentation controls are necessary as a pre -storm mitigative measure. This is usually accomplished by requiring sufficient vegetation and ground cover to slow flowing water velocities and to ' stabilize soil particles. Such controls also serve as helpful post - storm recovery guidelines to ensure land disturbing activities associated with construction and rebuilding do not adversely affect ' the environment.

EMERGENCY OPERATIONS PLAN The introduction to this report emphasizes that this Plan is not an emergency operations plan (EOP). Such plans have been prepared by the Town and the County to respond on a short term basis to crisis ' situations, ranging from hazardous waste spills to major storm events. As the name implies, these plans are operational in nature, oftentimes setting emergency procedures for marshaling people and ' equipment in very rapid order to deal with the immediate needs of those persons affected by the emergency event. H Town of Kill The Town of Kill Devil Hills has organized emergency operational Devil Hills EOP . plans by department. Each Town department writes, updates and participates in an annual hurricane drill to refine emergency operations, policies, and procedures. These plans are maintained in the Town Manager's office and in each respective department office. Dare County As required by General Statutes 166A-2, Dare County has organized E O P and planned for the protection of life and property from the effects of hazardous events. The purpose of the County's Emergency Operations Plan is to predetermine actions to be taken by governmental agencies and private organizations to reduce the vulnerabilities of people and property to disaster, and to establish capabilities to respond effectively before, during, and after an actual disaster. This Plan is implemented by the Dare County Control Group, which consists of the Dare County Chairman of the Board of Commissioners, the five municipal mayors, the Superintendent of the Cape Hatteras National Seashore, and the Dare County Sheriff.

POST -STORM RECONSTRUCTION ' Reconstruction Following a major storm, an important objective of this Plan is to management: provide for a post -disaster redevelopment activity that takes ' maximum advantage of mitigation opportunities. Such opportunities should act to reduce the amount of private property and number of lives at risk and to eliminate or reduce the potential exposure of ' public investments to a similar hazard. To accomplish this objective, administrative policies to assist planning and redevelopment decision -making are provided as follows: ' 1. Temporary After a storm causing major damages, the Town will be swamped 9 p Reconstruction with requests by individuals to rebuild their structures immediately. Moratoria Typically, the pressure to rebuild will be great. If there is no contingency mechanism in place to deal with such situations, the Town may find itself in a difficult situation to deal fairly and rationally ' with such requests. One effective approach to this problem is the immediate declaration ' of a temporary moratorium on building and development permits. Such a moratorium would allow the Town to mobilize the necessary planning and building inspection, utilities, public safety, and other ' support personnel— locally and from other communities. It would also provide sufficient time for the local damage assessment team to complete its job and for the Task Force to consider appropriate mitigation measures. Once the damage assessment is completed, the moratorium can be lifted for some or all parts of the town. To provide advanced planning for the employment of temporary moratoria, the following guidelines are set forth: ' Declaration Of A Major Disaster Or Emergency and Subsequent Buildina Moratorium Upon the declaration of a major disaster or emergency by the ' President of the United States, the Governor of North Carolina or the Mayor of Kill Devil Hills, a reconstruction moratorium shall be in effect for 48 hours. The purpose of the temporary moratorium shall be to ' protect lives and property and allow the Town to safely reestablish acceptable levels of public order and services. No building permits will be issued during this period. The Mayor or Board of Commissioners may extend the initial moratorium until such time as the state of emergency no longer exists. ' 2. Outstanding Building permits approved prior to the disaster event shall be building permits. revoked and not reissued for a period 30 days following expiration of ' Town of Kill Devil Hills and Glenn Harbeck Associates Page 6-1 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 6. Post Storm Reconstruction I , the initial moratorium. There will be no charge to apply for renewal of the permit. 3. Building Permit To deal with the large number of requests for permits after a major , Triage storm, the Town shall employ a "building permit triage" for orderly issuance of building permits. Permits will be issued based on the structure's function in bringing the community back to a normal state. ' This triage includes priorities for permitting critical facilities as identified in the Critical Facilities Inventory. (See Appendix 8) Generally, the following criteria shall be implemented: , First Priori Facilities critical for recovery of the Town and associated , services will be given priority status and primary consideration. Second Priority Primary residences and pre-existing commercial establishments will be given a very high priority for issuance of permits. A valid NC Drivers License with a Kill Devil Hills address will provide proof of residency. Third Priority Vacation homes, accessory use structures, new building permit applications, new subdivision applications and other structures will become a moderate priority. 4. Site plans. The Town staff, Planning Board or Board of Commissioners will not review site plans for proposed new work for a period of 30 days following expiration of the initial moratorium period. 5. Incipient inlet Upon recommendation by the Reconstruction Task Force, the Board areas. of Commissioners may order a building permit moratorium on any land bordering an incipient inlet high hazard area. No permits shall be approved until the inlet is closed and/or the area is stabilized. 6. Miscellaneous. No new site plans, zoning requests or subdivision plats will be accepted by the Town for thirty days following expiration of the initial moratorium. 7. Emergency Minimum emergency repairs that are required to prevent injury or repairs. further damage may be undertaken during any moratorium period. 8.

The structure is damaged or destroyed by flooding, wind or wave action, beach erosion or other result of a coastal ' hazard, to the extent of 50%, or greater of its tax value as determined by the Dare County tax assessor. Also, as provided for under Article 6, Section 21-6.1, paragraph D of ' the Kill Devil Hills Town Code, any non -conforming structure may be rebuilt to 100% of its previous use provided that: (1) the damage occurred within 30 years beginning November 18, 1991, and (2) the ' reconstruction is approved by issuance of a conditional use permit. (For more information about how non -conformities are handled, a copy of Article 6 of Town Zoning Ordinance —Non -conformities, is ' included as Appendix 3 to this report.) ' Site preparation All natural vegetation which is damaged or destroyed during the reconstruction process shall be replaced. No sand may be removed from the site, and dune systems are to be undisturbed. Construction ' may not decrease the elevation of the site. In addition, the site — including dunes —is to be returned to the original contours which existed prior to the disaster to the maximum extent possible. In the event that substantial volumes of sand are deposited on the site , during a storm event, such deposits may be removed and returned to the ocean shoreline AEC, as approved by the local CAMA permit officer. ' Acquisition of In some instances, property acquisition may be the most effective ' property way of reducing exposure to many of the storm hazards evident in Kill Devil Hills. The aftermath of a disaster event may serve as an opportunity for substantial progress in hazard mitigation by the rapid ' acquisition of land. In this regard, the Town intends to take advantage of these opportunities. The Town will identify, in advance, priority areas for consideration of acquisition and will identify funding ' sources to accomplish such activity. Underlying this effort will be other beneficial objectives such as the provision of open space, recreation sites and considerations to improve the economic vitality , of Kill Devil Hills.

STORM HAZARD MITIGATION AND POST -DISASTER RECONSTRUCTION ' POLICIES ' This section provides an overview of specific policies and actions which the Town will implement in support of storm hazard mitigation and post -disaster reconstruction. Together, these policies and actions comprise an integrated strategy for reducing death and ' destruction related to major storm events. r For convenience, policies and actions are presented in two general categories according to whether their effect is felt before the storm or after. The easiest way to determine the category is to apply one of two questions to each policy or action: All of the policies and actions have been arranged in one of two action matrices, corresponding to the category of effect noted above. In each matrix, the party responsible for carrying out the item is identified, and an approximate time frame for seeing it done is suggested.

Short term ' Lightning This analysis will attempt to formulate the hazards potential for Kill Devil Hills by ' describing the storms in List A by the use of causal phenomena in List B. Hurricanes ' Hur ricanes are the most destructive force threatening Kill Devil Hills. A hurricane is a cyclonic storm formed and fueled through the release of latent heat from ocean water condensation. It resembles a large, shallow funnel. Its primary characteristics are strong circular counter -clockwise winds, ranging from 75 mph to as much as 200 mph. (See Saffir/Simpson Damage Potential Scale for characteristics associated with ' hurricanes of various sustained wind speeds.) While a hurricane system may have a radius of 1,000 kilometers, hurricane force winds are usually confined within 100 kilometers of the storm's center. The storm's center consists of a cylindrical wall of clouds, where winds are at their strongest and barometric pressure is the lowest. Surrounded by this wall of clouds is the hurricane's "eye," an area of relative calm several miles in diameter which has little wind drain (See fig. 1.1). ' Atlantic hurricanes begin as low -intensity storm systems and form predominantly in the Caribbean Sea and the western Atlantic Ocean, although some storms which affect the United States coast originate off the west coast of Africa. Following initial formation, storm systems pass through increasingly intense phases, classified as tropical depressions (winds less than 40 miles per hour), tropical storms (winds between 40 and 73 miles per hour), and hurricanes (winds 74 miles per hour or greater).

Hazard Identification and Evaluation HURRICANES IN COASTAL NORTH CAROLINA. Along the North Carolina coast, hurricanes tend to be more frequent in late summer and early fall. While the hurricane season runs from June through November, over ninety percent of all recorded hurricanes have occurred in August, September, and October. In terms of storm frequency, coastal North Carolina is one of the more hurricane vulnerable locations along the coastline of the United States. Since 1886, 46 hurricanes have directly affected the Eastern North Carolina Study area. For the period 1872-1885, insufficient data exists to accurately determine which of the tropical cyclones that occurred might have reached hurricane intensity; therefore, for the period of record, 46 hurricane occurrences for the North Carolina coast is probably a conservative estimate. Coastal North Carolinians' experiences with hurricanes date back to the earliest settlers. Since 1899, North Carolina has received direct hits from 22 hurricanes, eight of them classified as "major" (a 3, 4, or 5) on the Saffir/Simpson Scale (Neumann et al., 1981, p.. 28). These are cases where the center of the storm passed directly over the North Carolina coast. The state has also suffered damages from numerous hurricanes whose centers came through South Carolina or stayed at sea, passing close to the North Carolina coast. The probability that a section of the North Carolina coastline will be directly hit by a ' hurricane in any given year ranges from six percent near Wilmington to 11 percent around Cape Hatteras. l J Hurricanes tend to follow a parabolic path, moving westward across the Atlantic and Caribbean and curving north or northeast as they move out of the tropics and into the westerly air currents of higher latitudes. The forward movement of the hurricane system is relatively slow, usually around 15 miles per hour, but exceptions are not unknown. For example, Hurricane Hazel had a forward speed of between 25 and 35 miles per hour. As Hurricanes move out of the tropics, their movement increasingly depends on air flow patterns in the higher latitudes, which are generally unsteady and unpredictable. A hurricane moving on a "normal" parabolic path may stop dead in its track, reverse direction, or take a sharp turn, all in response to changes in atmospheric currents. Except for Hurricane Emily, North Carolina has not experienced major damage from a hurricane in over ten years, when Hurricane Ginger made landfall near Morehead City. While no one was killed, damage was estimated at ten million dollars and include thousands of acres of corn and soybeans in the eastern counties (Baker, 1978, p. 73). In 1979, Hurricane David made landfall in South Carolina and moved inland. Most of the storm activity was centered over the Piedmont, but coastal North Carolina did not escape entirely. Massive erosion was triggered from Sunset Beach to Topsail Beach; thirty to forty feet of beach were lost at Holden Beach and Yaupon Beach. Several fishing piers were damaged, but overall property loss was low, and no deaths occurred. Town of Kill Devil Hills and William C. Schmidt Page 8-3 I Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report: ' Hazard Identification and Evaluation This is slight in comparison to the hurricanes which devastated North Carolina in the 1 mid-1950's. Between August 1953 and September 1955, seven hurricanes, four of them (Hazel, Connie, Diane, and lone) classified as major storms, rocked the Carolina ' coast. Damage from these storms was estimated to be in excess of 300 million dollars (1955 dollars) (N.C. Council on Civil Defense, 1955, pp. 21-23). The increase in development since this time leaves coastal North Carolina vulnerable for even greater ' damage today. Hurricane Hazel ' An account of Hurricane Hazel as it passed through the North Carolina coast on October 15, 1954, illustrates the damages a hurricane can cause in coastal communities. Hazel made landfall and began its path of destruction at Little River, ' South Carolina. Wind velocities were estimated at 140 miles per hour, and the storm surge exceeded 14 feet; Hazel ranks as a 4 on the Saffir/Simpson Scale. Every fishing pier was destroyed from Myrtle Beach, South Carolina, to Cedar Island, North ' Carolina— a distance of 170 miles (Dunn and Miller, 1960, p. 251). On Ocean Isle, North Carolina, all people were evacuated, but all buildings were destroyed, as were all 200 buildings at Holden Beach. At Long Beach, 352 of 357 homes were lost. In ' Carolina Beach, 475 buildings were totally destroyed, and 1,365 suffered damages. Over 100,000 cubic yards of sand were deposited on the streets of Carolina Beach due to flooding, wave action, and high winds (Dunn and Miller, 1960, p. 252). ' Wrightsville Beach was submerged in five feet of water; 89 homes were lost there. A total of 19 people died that day. The number could easily have been much higher. The total damage caused by Hurricane Hazel was $125,309,000 (N.C. Council on Civil Defense, 1955, p. 21). Because Hazel arrived after harvest time, damage to crops was relatively light, but damage to farm buildings exceeded $50,000,000. Damages to ' forests totaled $3,000,000. Damages to the fishing industry were approximately $1,500,000. Costs of repairs and replacements of public highways were $500,000. Damage to municipal and county public facilities exceeded $8,000,000. Four ' thousand homes and 1,000 commercial and industrial buildings were completely destroyed or suffered major damage. Minor damage was sustained by 20,000 dwellings and 4,000 business and industrial buildings and amounted to about $60,000,000. Damages to churches and public schools were estimated at $1,000,000. , Between the years 1899 and 1980, there have been 138 hurricanes which have ' crossed the United States coastline, for an approximate annual average of 1.7. (See Fig 2.1 ) Of these, 56 have been classified as major— that is hurricanes which are classified as a Category 3 or larger. Florida has received the largest number of hurricane landfalls followed by Texas, Louisiana and North Carolina ' Town of Kill Devil Hills and William C. Schmidt 1 Page 8-4 I' ' Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report. Hazard Identification and Evaluation HURRICANE WINDS ' A hurricane is identified primarily in terms of its high winds and low atmospheric pressure; by definition, a hurricane is a tropical weather disturbance with winds ' exceeding 73 miles per hour. Where a hurricane is moving directly shoreward at 14 to 17 miles per hour, winds can be expected to reach hurricane force at the open shoreline three to six hours before the eye makes landfall (Simpson and Riehl, 1981, p. 212). In a hurricane of moderate strength, winds will increase as the hurricane center approaches, reaching maximum sustained speeds of about 100 miles per hour at sea level with peak gusts of over 130 miles per hour as the center moves onshore. In an extreme hurricane, sustained winds may exceed 165 miles per hour at the coast, ' with peak gusts exceeding 200 miles per hour. A hurricane's strongest winds appear in the leading right-hand quadrant of the storm system (see Figure 2.4). ' Hurricane -force winds for the average hurricane are approximately 100 miles in diameter and some 350-400 miles across in gale force winds. ' Wind circulation can be divided into three zones: (1) the outer zone with wind speeds as low as 20-30 mph, extending to within 20- to 30-miles of the center where winds may be as high as 120-150 mph; (2) a region of maximum (and constant) winds surrounding the eye; and (3) the eye itself, which is relatively calm. The average diameter of the hurricane eye is approximately 15 miles, commonly extending to 25 miles in larger, more mature hurricanes. ' In addition to high sustained winds, hurricanes can generate gusts from 25 to 50 percent higher than sustained levels. As we have said, the highest winds are found in ' the upper right-hand quadrant of the moving hurricane directly surrounding the storm eye. The magnitudes of wind speed once the hurricane has reached landfall will depend on local characteristics of the natural and built environments. For example, trees and other natural features can slow sustained winds and in turn provide ' protection for people and property. As the storm moves inland, friction from the land surface will generally dissipate the ' high winds. However, a narrowing zone of major wind damage, 30 to 35 percent of that at the shoreline, can extend much further inland (Simpson and Riehl, 1981, p. 214). Little or no change in wind speed occurs above 100 meters elevation either at the shore or inland. In fact, winds at 100 meters elevation are generally 30 to 50 percent stronger than those recorded at sea level (Simpson, 1981, p. 213). ' In addition to the regular wind pattern around the eye, tornadoes may sometimes accompany a hurricane. This is not a well -understood phenomenon nor does it occur in all hurricanes. These tornadoes behave much as the more common Midwestern variety and can cause considerable damage. Hurricane Agnes, for example, spawned some 15 tornadoes in Florida, resulting in total property losses of 4.5 million dollars (Baker, 1978, p. 25). ' The hurricane system, with its high winds and low pressure moving across the open p ocean, pushes up an enormous swell of water before it. This mass of water, called the ' Town of Kill Devil Hills and William C. Schmidt Page 8-5 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report. , Hazard Identification and Evaluation storm surge, can cause extreme elevations in mean sea level and can lead to coastal ' flooding. The height of the surge along the open coast depends on a number of factors which include wind speed, normal water depth, storm trajectory, and forward speed of ' the storm. A hurricane storm surge coinciding with the natural high tide can cause even greater damage. As with the hurricane's winds, the surge is highest in the leading right quadrant of the storm system. ' HURRICANE STORM SURGE Storm surge is the most significant effect of hurricanes and the element of a hurricane ' most responsible for loss of life. The surge does not strike the coast as a wall of water like the tsunami, but instead as a rapid elevation in sea level. The surge represents the "amount of water pushed upwind ahead of a hurricane advancing landward from a ' large body of water." Surge is created through several key physical effects associated with hurricanes: 1. the pressure effect 2. the direct wind effect 3. the effect of the earth's rotation 4. the effect of waves I 5. the rainfall effect. The pressure effect results from the dramatic reduction in barometric pressure that ' accompanies a hurricane, causing an upward suction action on sea level. It is estimated that for each inch reduction in barometric pressure, an accompanying foot of sea level rise will result. The direct wind effect is the most significant influence on , surge. Hurricane winds generate surface currents that, when confronted by a coastline, create tremendous wind "set-up" effects and result in high surge levels. The extent of this set-up effect is highly dependent upon the configuration of the coastline. For example, the existence of bays and estuaries may serve to "funnel" wind -driven ' surges, increasing the natural set-up, and creating a "piling -up" effect. Consequently, the shallower the water close to shore, the greater will be the piling -up ' of surge. Because the area of greatest winds is found in the upper right quadrant of the moving hurricane, the area of greatest surge tends to be from 10 to 35 miles to the right of the hurricane track. ' The influence of the earth's rotation in the Northern Hemisphere is to increase any current's movement to the right and the effects of this factor will depend on the precise ' configuration of the coastline. The character of the surge as felt on the coast will be dependent upon a number of ' factors, including the following: 1. shoreline configuration 2. existence of bays and estuaries where waters can converge 3. off -shore bottom conditions (bathymetry) 4. land elevation (topography) 5. the characteristics of the storm itself (see previous sections). I Town of Kill Devil Hills and William C. Schmidt Page 8-6 , ' Storm Hazard Mitigation and Post -Disaster Reconstruction Plan B. Supplemental Report. Hazard Identification and Evaluation ' It is clear that shore bottom configuration has much to do with the kind of surge experienced and, in turn, the type of damages experienced. A sloping sea bottom, ' shallow close to shore, will tend to generate, for example, a high degree of surge run- up. This run-up effect will be even more extensive in circumstances where bays and estuaries exacerbate the run-up by funneling it, thus flooding areas at greater ' elevation. On the other hand, steeply sloping shorelines, in which water is deeper closer to shore, will reduce the surge run-up effect, but will permit breaking waves closer to shore, i.e., with attendant structural damages to buildings on the immediate ' shoreline. Land elevation is a key element in predicting extent of surge effect, and where land has been subsiding, for whatever reasons, we can expect more extensive effects. Evidence suggests that sea level has and will continue to rise, making the surge effects of the hurricane even more significant. ' The extent and damage from hurricane storm surge is also influenced by the existence of high or low tide when the storm comes ashore. In areas along the coast where the ' size of the tide is substantial, this factor can sometimes mean the difference between a minor surge or a devastating surge. ' HURRICANE -RELATED FLOODING The hurricane's storm surge and its excessive precipitation cause massive coastal and ' riverine flooding. About 90 percent of hurricane deaths result from drowning; the majority of property damages result from flooding. ' The flooding of coastal areas with sea water not only causes extensive damage to buildings and their contents but also may render agricultural land useless for most crops by contaminating soils with salt water. During the North Carolina hurricanes of ' 1954 and 1955 (Hazel, Connie, Diane, and lone), most of the land less than 10 feet above sea level suffered from salt water intrusion and extensive crop damages. About 25 percent of the area of 22 eastern counties was estimated to have been covered by ' fresh and salt water during these hurricanes (N.C. Council on Civil Defense, 1955, p. 28). In addition, flotsam, including boats or other structures lifted by the hurricane surge and pushed by winds, may be transported inland and become battering rams, causing additional damage. The contribution of the hurricane's excessive rainfall to coastal flooding is difficult to separate from the storm surge. However, in inland streams, this rainfall can cause ' significant flooding. Rainwater can flood areas that the storm surge cannot reach. This freshwater flooding may be as destructive as the storm surge. Figure 2.6 shows the extent of freshwater flooding and salt water flooding in Albemarle Sound due to the ' hurricanes of 1954 and 1955. Widely differing levels of precipitation have been reported for different hurricanes, ' ranging from practically nothing (in spite of hurricane -force winds) to over 40 inches for any one place along the storm's path. Hurricane Frederic, which struck the Louisiana, Alabama, Mississippi, and Florida coasts in September of 1979, showed a typical ' rainfall pattern. The National Weather Service station at Mobile, Alabama, recorded 8.6 inches of rain before its gauge was blown away. An 11-inch gauge overflowed at the home of the Civil Defense Direction in Pascagoula, Mississippi. The highest official ' Town of Kill Devil Hills and William C. Schmidt Page 8-7 1 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report. Hazard Identification and Evaluation reported rainfall for a 24-hour period during Frederic was 9 inches (U.S. Army Corps of Engineers, 1981, p. 59). A hurricane may continue to deposit heavy rainfall far inland. Hurricane Frederic, upon making landfall on the gulf coast, continued to move north with declining wind speeds but continuing heavy precipitation. Akron, Ohio, recorded over 8 inches of rain due to Frederic (U.S. Army Corps of Engineers, 1981). Hurricane Agnes did damage in excess of two billion dollars in the Northeast in 1972; the vast majority of this damage came from heavy precipitation and riverine flooding in Pennsylvania, New York, and adjacent states. HURRICANE -RELATED WAVE ACTION An important component of the storm surge is the wind -driven waves which ride on top of the surge and can cause extensive damage. The effects of waves during hurricanes can be extreme. A breaking wave carries a large momentum and can "run up" on a sloping shore to elevations considerably higher than the height of the wave itself. The size of the waves is tied to the direction and speed of the wind, the water depth, and the normal direction of wave movements. The height of these waves also depends partly on the slope of the ocean bottom near the shore. A gently sloping coast will see minimal wave action; areas where the ocean bottom falls off rapidly will experience higher waves. High storm waves appear not only on the ocean, but also on broad sounds where there is enough water depth and fetch for high winds to push up a wave. The height of storm waves is generally about 50 percent of the depth of the storm surge For instance, with a static storm surge of 10 feet, 5 foot waves could be expected to occur on top of this surge. In this case the total combined surge and wave height would be 15 feet. The influence of waves in generating coastal property damages has in recent years been appreciated. The National Flood Insurance Program now incorporates wave height into its computation of base flood elevations in coastal areas. Waves on top of a storm surge can have several important effects. First, the waves can reach and flood areas not reached by the surge itself. Second, waves act as direct battering forces. The force of a wave against a structure is a function of the size of the wave and the speed at which it is moving. Finally, waves may be responsible for massive erosion along beaches, dunes, and wherever they reach. Inland from an open coast or a bay shore, waves become diffracted and their energies dispersed by buildings, dunes, or forested areas; consequently, wave damages diminish. HURRICANE -RELATED EROSION Extreme winds, high waters, and heavy wave action may accelerate or change normal patterns of wave movement and sand transport to cause drastic shoreline changes, especially on a barrier island. The coastline may change shape, and new inlets may form in response to the energy of a single storm.

The .geological history of North Carolina's coastline attests to the power of hurricanes and other storms and their ability to erode beaches and open and close inlets. Inlets tend to form or widen after a storm surge builds up within a sound and gravity pushes the water back out to sea. In 1967, Hurricane Beulah cut 31 inlets through Padre Island, Texas; most of these breaches gradually filled back in. In addition to severe erosion along the ocean shoreline, severe erosion can also occur along estuarine shorelines as waves travel across broad sounds and batter beaches and bluffs.

Supplemental Report. t Hazard Identification and Evaluation Tornadoes Tornadoes are rapidly rotating winds that blow around a small area of intense low pressure. Sometimes called twisters or cyclones, tornadoes nearly always begin as a funnel -shaped cloud that looks like an elephant's trunk hanging from a large cumulonimbus cloud (Fig. 16.21) . The funnel cloud is called a tornado only after it touches the ground. When viewed from above, the majority of tornadoes rotate counterclockwise. A few have been seen rotating clockwise, but these are rare. The diameter of most tornadoes is between 100 and 600 m, although some are just a few meters wide and others have diameters exceeding 1600 m (1 mi). Tornadoes that form ahead of an advancing cold front are often steered by southwesterly winds and therefore tend to move from the southwest toward the northeast at speeds usually between 20 and 40 knots. However, some have been clocked at speeds greater than 70 knots. Most tornadoes last only a few minutes and have an average path length of about 7 km (4 mi). There are cases where they have traveled for hundreds of kilometers and have existed for many hours, such as the one that lasted over 7 hours and cut. a. path 470 km (292 mi) long through portions of Illinois and Indiana on May 26,1917. Each year, tornadoes take the lives of many people. The yearly average is about 100, although over 100 may die in a single day. The deadliest tornadoes are those that occur in families; that is, different tornadoes spawned by the same thunderstorm. Some thunderstorms produce a sequence of several tornadoes over two or more hours and over distances of 100 km or more. Tornado families usually form along squall lines and often constitute what is termed a tornado outbreak. One of the most violent outbreaks ever recorded occurred on April 3 and 4,1974. During a 16 hour period, 148 tornadoes cut through parts of 13 states, killing 307 people, injuring more than 6000, and causing an estimated $600 million in damage. Some of these tornadoes were among the most powerful ever witnessed. The combined path of all the tornadoes during this super outbreak amounted to 4181 km (2598 mi), well over half of the total path for an average year. The greatest loss of life attributed to tornadoes occurred during the tri-state outbreak of March 18,1925, when an estimated 695 people died as 7 tornadoes traveled a total of 703 km (437 mi) across portions of Missouri, Illinois, and Indiana. In yet another outbreak, on Palm Sunday, 1965, more than 30 tornadoes moved through 5 midwestern states, inflicting great damage and killing 256 people. Obviously, when a powerful tornado reaches the ground, it is capable of inflicting great damage on everything in its path. Because of this, few people have ever witnessed the inside of a tornado and lived to tell about. However, Will Keller, a Kansas farmer, has. His account, as told to Alonzo A. Justice of the Weather Service office in Dodge City, is given in the Focus section on the following page. Town of Kill Devil Hills and William C.

V ICWIIIH UIC 111blUC 01 a 1 ornado On the afternoon of June 22, 1928, 1 was out in my field with my family looking over the ruins of our wheat crop which had just been completely destroyed by a hailstorm. I noticed an umbrella -shaped cloud in the west and southwest and from its appearance suspected that there was a tornado in it. The air had that peculiar oppressiveness which nearly always precedes a tornado. I saw at once that my suspicions were correct, for hanging from the greenish black base of the cloud were three tornadoes. One was perilously near and apparently heading for my place. I lost no time hurrying my family to our cyclone cellar. The family had entered the cellar and I was in the doorway just about to enter and close the door when I decided to take a last look at the approaching twister. I have seen a number of these, so I did not lose my head, although the approaching tornado was an impressive sight. The surrounding country is level and there was nothing to obstruct the view. There was little or no rain falling from the cloud. Two of the tornadoes were some distance away and looked like great ropes dangling from the parent cloud, but the one nearest was shaped more like a funnel, with ragged clouds surrounding it. It appeared much larger and more energetic than the others and occupied the central position of the cloud, with a massive cumulus dome being directly over it. Steadily the tornado came on, the end gradually rising above the ground. I probably stood there only a few seconds, but was so impressed with the sight that it seemed like a long time. At last the great shaggy end of the funnel hung directly overhead. Everything was as still as death. There was a strong, gassy odor and it seemed as though I could not breathe. There was a screaming, hissing sound coming directly from the end of the funnel. I looked up and, to my astonishment I saw right into the heart of the tornado. There was a circular spinning in the center of the tornado, about 50 to 100 feet in diameter, which extended straight up for a distance of at least one-half mile. As best I could judge under the circumstances. The walls of this opening were rotating clouds and the whole was brilliantly lighted with constant flashes of lightning which zig-zagged from side to side. Had it not been for the lightning I could not have seen the opening, or any distance into it. Around the lower rim of the great vortex, small tornadoes were constantly forming and breaking away. These looked like tails as they writhed their way around the end of the funnel. It was these that made the hissing sound. I noticed that the direction of rotation of the great whirl was counterclockwise, but some of the smaller tornadoes rotated clockwise. The opening was entirely hollow, except for something I could not exactly make out — perhaps a detached wind cloud— that kept moving up and down. The tornado was not traveling at a great speed so I had plenty of time to get a good view of the whole thing, inside and out. Will Keller, Kansas Farmer ITown of Kill Devil Hills and William C. Schmidt Page 8-11 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report. , Hazard Identification and Evaluation TORNADO OCCURRENCE Tornadoes occur in many parts of the world, but no country experiences more tornadoes than the United States, which averages more than 700 annually. Although tornadoes have occurred in every state, including Alaska and Hawaii, the greatest number occur in the "tornado belt" of the Central Plains, which stretches from central Texas to Nebraska. * (See Fig. 16.22.) The Central Plains region is most susceptible to tornadoes because it provides the proper atmospheric setting for the development of the severe thunderstorms that spawn tornadoes. Here (especially in spring) warm, humid surface air is overlain by cooler, *Many of the tornadoes that form along the Gulf Coast are generated by thunderstorms embedded within the circulation of hurricanes. dryer air aloft, producing an unstable atmosphere. When a strong vertical wind shear exists and the surface air is forced upward, large thunderstorms capable of spawning tornadoes may form. Therefore, tornado frequency is highest during the spring and lowest during the winter when the warm surface air is absent. About three -fourths of all tornadoes in the United States develop from March to July. The month of May normally has the greatest number of tornadoes (the average is about 5 per day) while the most violent tornadoes seem to occur in April, when horizontal and vertical temperature and moisture contrasts are greatest. Although tornadoes have occurred at all times of the day and night, they are most frequent in the late afternoon (between 4:00 P.M. and 6:00 P.M.), when the surface air is most unstable; they are least frequent in the early morning before sunrise, when the air is most stable. Although large, destructive tornadoes are most common in the Central Plains, they can develop anywhere if conditions are right. For example, a series of at least 36 tornadoes, more typical of those that form over the plains, marched through North and South Carolina on March 28, 1984, claiming 59 lives and causing hundreds of millions of dollars in damage. One tornado was enormous, with a diameter of at least 4000 m (2.5 mi) and winds that exceeded 200 knots. No place is totally immune to a tornado's destructive force. On March 1, 1983, a rare tornado cut a 5-km swath of destruction through downtown Los Angeles, California, damaging more than 100 homes and businesses and injuring 33 people. Even in the central part of the United States, the statistical chance that a tornado will strike a particular place this year is quite small. However, tornadoes can provide many exceptions to statistics. Oklahoma City, for example, has been struck by tornadoes at least 32 times in the past 90 years. And the little town of Codell, Kansas, was hit by tornadoes in 3 consecutive - years-1916, 1917, and 1918—and each time on the same date: May 20! Considering the many millions of tornadoes that must have formed during the geological past, it is likely that at least one actually moved across the land where your home is located, especially if it is in the Central Plains. 0 11 0 1, Town of Kill Devil Hills and William C. Schmidt Page 8-12 ' Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report. Hazard Identification and Evaluation ' TORNADO WINDS ' The strong winds of a tornado can destroy buildings, uproot trees, and hurl all sorts of lethal missiles into the air. People, animals, and home appliances all have been picked up, carried several kilometers, then deposited. Tornadoes have accomplished ' some astonishing feats, such as lifting a railroad coach with its 117 passengers and dumping it in a ditch 25 m away. Showers of toads and frogs have poured out of a cloud after tornadic winds sucked them up from a nearby pond. Other oddities include chickens losing all of their feathers and pieces of straw being driven into metal pipes. ' Miraculous events have occurred, too. In one instance, a schoolhouse was demolished and the 85 students inside were carried over 100 m without one of them being killed. ' Our knowledge of the furious winds of a tornado comes mainly from observations of the damage done and the analysis of motion pictures. Because of the destructive ' nature of the tornado, it was once thought that it packed winds greater than 500 knots. However, studies conducted after 1973 reveal that even the most powerful twisters seldom have winds exceeding 220 knots, and most tornadoes probably have winds of less than 125 knots. Nevertheless, being confronted with even a small tornado can be ' terrifying. The high winds of the tornado cause the most damage as walls of buildings buckle and collapse when blasted by the extreme wind force. Also, as high winds blow over a roof, lower air pressure forms above the roof. The greater air pressure inside the building then lifts the roof just high enough for the strong winds to carry it away. A similar effect occurs when the tornado's intense low-pressure center passes overhead. Because the pressure in' the center of a tornado may be more than 100 mb (3 in.) ' lower than that of its surrounding, there is a momentary drop in outside pressure when the tornado is above the structure. It was once thought that opening windows and allowing inside and outside pressures to equalize would minimize the chances of the ' building exploding. However, it now appears that opening windows during a tornado actually increases the pressure on the opposite wall and increases the chances that the building will collapse. Damage from tornadoes may also be inflicted on people and structures by flying debris. Hence, the wisest course to take when confronted with an ' approaching tornado is to seek shelter immediately. At home, take shelter in a basement. In a large building without a basement, the safest ' place is usually in a small room, such as a bathroom, closet, or interior hallway, preferably on the lowest floor and near the middle of the edifice. At school, move to the hallway and lie flat with your head covered. In a mobile home, leave immediately and ' seek substantial shelter. If none exists, lie flat on the ground in a depression or ravine. Don't try to outrun an oncoming tornado in a car or truck, as tornadoes often cover erratic paths with speeds sometimes exceeding 70 knots. If caught outdoors in an ' open field, look for a ditch, stream bed, or ravine, and lie flat with your head covered. When a tornado is approaching from the southwest, its strongest winds are on its ' southeast side. We can see why in Fig. 16.23. The tornado is heading northeast at 50 knots. If its rotational speed is 100 knots, then its forward speed will add 50 knots to its southeastern side (position D) and subtract 50 knots from its northwestern side Town of Kill Devil Hills and William C.

Because the most destructive and extreme winds will southeastern side, it is the southwest side of the building that will impact of the winds. be on the tornado's ' receive the maximum It now appears that the most violent tornadoes (with winds exceeding 180 knots) contain smaller whirls that rotate within them. Such tornadoes are called multi -vortex tornadoes and the smaller whirls are called suction vortices (Fig. 16.24). Suction vortices are only about 10 m (30 ft) in diameter, but they rotate very fast and apparently do a great deal of damage. In the late 1960s, Dr. T. Theodore Fujita, a noted authority on tornadoes at the University of Chicago, proposed a scale (called the Fujita scale) for classifying tornadoes according to their rotational wind speed and the damage done by the storm. Table 16.1 presents this scale. Statistics compiled by the staff of the National Severe Storms Forecast Center in Kansas City, Missouri, show that, of all the tornadoes reported between 1950 and 1980, about two-thirds were FO and F1 (weak tornadoes) and only 2 percent were above the F3 classification (violent). However, it was these latter storms that accounted for over two-thirds of all tornado -related deaths. As an example, a powerful F5 tornado devastated the town of Barneveld, Wisconsin, on the morning of June 8,1984. Although the tornado lasted for no more than a minute, it damaged or destroyed 90 percent of the buildings, took the lives of 9 people, and injured 190 more. A powerful F4 tornado is shown in Fig. 16.25.

Schmidt Page 8-14 1 ' Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report. Hazard Identification and Evaluation TORNADO FORMATION ' Although everything is not known about the formation of a tornado, we do know that tornadoes tend to form with severe thunderstorms and that unstable air is essential for ' their development. One atmospheric situation that frequently leads to severe thunderstorms with tornadoes in the spring is shown in Fig. 16.26. At the surface, we find an open wave middle latitude cyclone with its cold front and warm front. Behind the cold front is modified mP Pacific air that, having crossed several mountain ranges, is now relatively cold and dry. (It may also be cP air penetrating southward, east of the Rockies.) Ahead of the advancing cold front, warm ' and humid mT air pushes northward from the Gulf of Mexico. Above this warm sector at 850 mb, a wedge of warm, moist air is streaming northward. Directly above the moist layer, between 700 mb and 500 mb, is a wedge of cold, dry air —called a dry tongue — moving in from the southwest. At 500 mb, a trough of low pressure exists to the west of the surface storm and at 300 mb the polar front jet stream swings over the region. At this level, the jet stream takes air away so quickly that air from below is drawn up to ' replace it. The stage is now set for the development of severe storms. The position of cold air above warm air produces an unstable atmosphere. As the warm air rises from the surface, many thunderstorms should form throughout the warm sector. But often this is not the case as the atmospheric conditions that generate severe thunderstorms tend to prevent many smaller ones from forming. To see why, ' we will examine the vertical profile of temperature and moisture —a sounding —in the warm sector. Figure 16.27 shows a typical sounding of temperature and dew point in the warm sector before tornadoes occur. From the surface up to 800 mb, the conditionally unstable air is warm and very humid. At 800 mb, a shallow inversion acts like a cap on the moist layer below. Above the inversion, the air is cold and much drier. This air is also conditionally unstable, as the temperature drops at just about the dry adiabatic rate (10°C/1000 m). The cooling of this upper layer is due, mainly, to cold advection. Cold, dry, unstable air sitting above a warm, humid layer produces convective ' instability, which means that the atmosphere will become even more unstable if a layer of air is somehow forced upward. ' The lifting of warm surface air can occur at the frontal zones, but the air may also begin to rise anywhere in the warm sector when the surface air heats up during the day. However, in the morning, the inversion acts as a lid on rising thermals and only small ' cumulus clouds form. As the day progresses (and the surface air heats even more), rising air breaks through the inversion at isolated places and clouds build rapidly, sometimes explosively, as the moist air is vented upward through the opening. Thus, ' we can see that the inversion prevents many small thunderstorms from forming. When the surface air is finally able to puncture the inversion, the upper -level jet stream rapidly draws the moist air up into the cold, unstable air, and a large storm quickly ' develops. The severe thunderstorm soon builds to the tropopause, and an anvil forms. However, the strong updraft inside the storm causes its top to overshoot the anvil by 2 to 4 km. ' Town of Kill Devil Hills and William C. Schmidt Page 8-1 g 5 ' Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report. Hazard Identification and Evaluation In order for the storm to spawn a tornado, the updraft must rotate. Remember from our earlier discussion that severe thunderstorms form in a region of strong vertical wind shear. In Fig. 16.26, the rapidly increasing wind speed with height (vertical wind speed ' shear) and the changing wind direction with height —from southerly at low levels to westerly at high levels (vertical wind direction shear) —cause the updraft inside the storm to rotate cyclonically. This rising, spinning column of air, perhaps 5 to 10 km ' across, is called a mesocyclone. Doppler radar observations have shown that rotation begins in the middle of the thunderstorm and gradually works downward. As air rushes in toward the low pressure of the mesocyclone, the rotational wind speeds ' increase much like a spinning skater increases in speed when the arms are brought in closer to the body. (The conservation of angular momentum.) At the same time, the mesocyclone stretches vertically and shrinks horizontally (see Fig. 16.28), and the ' spinning air is accelerated upward. Inside the mesocyclone, which is now between 2 and 4 km wide, a spinning vortex of increasing wind speed (a tornado may —for reasons not fully understood —appear near the mid -level of the cloud and gradually , extend downward to the cloud base. At this point, the mesocyclone is called a tornado cyclone. As air rushes into the low-pressure vortex from all directions, it expands, cools, and, if sufficiently moist, condenses into a visible cloud —the funnel cloud. As the air beneath the funnel is drawn into the core, it cools rapidly and condenses, and the funnel cloud ' descends toward the surface. Upon reaching the ground it is called a tornado.. Here, it usually picks up dirt and debris, making it appear both dark and ominous. While the air along the outside of the funnel is spiraling upward, Doppler radar reveals that, within the core of violent tornadoes, the air is descending toward the extreme low pressure at ' the ground. As the air descends, it warms, causing the cloud droplets to evaporate. This process leaves the core free of clouds. At the surface, where the descending air in the core meets the air flowing into the funnel, suction vortices are formed as the ' combined flows spin and turn rapidly upward. Observations reveal that the most strong and violent tornadoes develop near the right ' rear sector of a severe thunderstorm (on the southwestern side of an eastward moving storm, Fig. 16.28). However, weaker tornadoes may not only develop in the main updraft, but along the gust front, where the cool down draft forces warm inflowing air ' upward. Although it appears that most strong and violent tornadoes form within the mesocyclone, not all mesocyclones produce tornadoes. Certainly, all the processes that go into generating a tornado are not completely understood at this time. ' While it is difficult to tell which thunderstorm will spawn a tornado, meteorologists can predict where tornado -generating storms are most likely to form. Notice in Fig. 16.26 ' that this area (the boxed -off area on the surface map) is situated where the polar front jet stream and the cold tongue of air cross the wedge of warm, moist air. Knowing this helps to explain why the region of greatest tornado activity shifts northward from winter ' to summer. During the winter, tornadoes are most likely to form over the southern Gulf states. The polar front jet is above this region, and the contrast between warm and cold air masses is greatest. In spring, humid Gulf air surges northward; contrasting air masses and the jet stream also move northward and tornadoes become more , prevalent from the southern Atlantic states westward into the southern Great Plains. In ' Town of Kill Devil Hills and William C. Schmidt Page 8-16 ' Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report., Hazard Identification and Evaluation ' summer, the contrast between air masses lessens, and the jet stream is normally near the Canadian border; hence, tornado activity tends to be concentrated from the ' northern plains eastward to New York State. OBSERVING TORNADOES ' The appearance of mammatus-type clouds at the base of a severe thunderstorm may indicate that the storm is capable of producing tornadoes. These bulging pouches suggest vertical motion and may extend well below the cloud base, as shown in Fig. ' 16.29. Mammatus clouds are not funnel clouds because they do not rotate. The first sign that the thunderstorm is about to give birth to a tornado is the sight of rotating clouds at the base of the storm. ' If the area of rotating clouds lowers, it becomes a wall cloud (compare Fig. 16.28 with Fig. 16.30). Usually within the wall cloud, a smaller, rapidly rotating funnel ' extends toward the surface. Sometimes the air is so dry that the swirling wind remains invisible until it reaches the ground and begins to pick up dust. Unfortunately, people have mistaken these "invisible tornadoes" for dust devils, only to find out (often too ' late) that they were not. Occasionally, the funnel cannot be seen due to falling rain, clouds of dust, or darkness. Even when not clearly visible, many tornadoes have a distinctive roar that can be heard for several kilometers. This sound, which has been ' described as "a roar like a thousand freight trains," appears to be loudest when the tornado is touching the surface. However, not all tornadoes make this sound and, when these storms strike, they become silent killers. ' When tornadoes are likely to form during the next few hours, a tornado watch is issued by the National Severe Storms Forecast Center in Kansas City, Missouri, to ' alert the public that tornadoes may develop within a specific area during a certain time period. Many communities have trained volunteer spotters, who look for tornadoes after the watch is issued. Once a tornado is spotted —either visually or on a radar screen —a tornado warning is issued by the local National Weather Service Office. In some communities, sirens are sounded to alert people of the approaching storm. Radio and television stations interrupt regular programming to broadcast the warning. Although not completely effective, this warning system is apparently saving many lives. ' Despite the large increase in population in the tornado belt during the past twenty years, tornado -related deaths have actually shown a decrease. ' In an attempt to unravel some of the mysteries of the tornado, several studies are under way. In one --conducted jointly by the University of Oklahoma and the National Severe Storms Laboratory in Norman, Oklahoma —still and motion pictures of ' tornadoes are correlated with radar data in an attempt to better estimate wind speeds. In another, a sturdy instrument package resembling a barrel with an antenna (called TOTO—for TOtable Tornado Observatory) is placed in the path of an approaching ' mesocyclone in hope of determining surface conditions such as winds, temperature, pressure, and the electric field strength beneath a tornado cyclone. The readings are recorded in TOTO's tornado -proof shell and read after the storm passes. Unfortunately, ' high winds would likely tip TOTO over before it could ever measure the strongest winds of a tornado. On the more theoretical side, numerical cloud modeling studies Town of Kill Devil Hills and William C. Schmidt Page 8-17 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report. ' Hazard Identification and Evaluation are offering new insights into the formation and development of tornado breeding thunderstorms. DOPPLER RADAR Most of our knowledge about what goes on inside a tornado -generating thunderstorm has been gathered through the use of Doppler radar. Before we investigate this remote -sensing device, we will examine how precipitation inside a severe thunderstorm appears on the scope of conventional radar. A conventional radar transmitter sends out microwave pulses in that, when this energy strikes an object, a small fraction is scattered back to the antenna. Because precipitation particles are large enough to bounce microwaves back to the antenna, the white area on the radar scope in Fig. 16.31 represents precipitation inside a severe thunderstorm. Notice that the pattern is in the shape of a hook. A hook -shape echo such as this indicates the possible presence of a tornado. The dark area within the hook echo represents the region inside the severe thunderstorm, where strong updrafts carry cloud particles upward so rapidly that they are unable to grow large enough to reflect microwaves. When tornadoes form, they do so near the tip of the hook. However, many severe thunderstorms (as well as smaller ones) do not show a hook echo, but still spawn tornadoes. Sometimes, when the hook echo does appear, the tornado is already touching the ground. Consequently, a better technique was needed in detecting tornado producing storms. To address this need, Doppler radar was developed. Doppler radar is like a conventional radar in that it can detect areas of precipitation and measure the speed of falling precipitation. But a Doppler radar can do more —it can actually measure the speed at which precipitation is moving horizontally toward or away from the radar antenna. Because precipitation particles are carried by the wind, Doppler radar can peer into a severe storm and unveil its winds. Doppler radar works on the principle that, as precipitation moves toward or away from the antenna, the returning radar pulse will change in frequency. A similar change occurs when the high-pitched sound (high frequency) of an approaching noise source, such as a siren or train whistle, becomes lower in pitch (lower frequency) after it passes by the person hearing it. This change in frequency is called the Doppler shift and this, of course, is where the Doppler radar gets its name. A single Doppler radar cannot detect winds that blow parallel to the antenna. Consequently, two or more units probing the same thunderstorm are able to give a three-dimensional picture of the winds within the storm. To help distinguish the storm's air motions, wind velocities can be displayed in color. Color contouring the wind field gives a good picture of the storm. (See Fig. 16.32.) Even a single Doppler radar can uncover many of the features of a severe thunderstorm. For example, studies conducted in the 1970s revealed, for the first time, the existence of the swirling winds of the mesocyclone inside tornado -producing thunderstorms. Mesocyclones have a distinct image (signature) on the radar display. About half of all the mesocyclones identified have been associated with tornadoes. J E r Town of Kill Devil Hills and William C. Schmidt Page 8-18 ' n ' Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report. Hazard Identification and Evaluation ' The time between mesocyclone identification and the tornado actually touching the ground is about 20 minutes. ' Tornadoes also have a distinct signature, known as the tornado vortex signature (TVS), which shows up as a region of rapidly changing wind speeds within the ' mesocyclone. Unfortunately, the resolution of the Doppler radar is not high enough to measure actual wind speeds of most tornadoes, whose diameters are only a few hundred meters or less. However, a new and experimental Doppler system —called Doppler Lidar—uses a light beam (instead of microwaves) to measure the change ' in frequency of falling precipitation, cloud particles, and dust. Because it uses a shorter wavelength of radiation, it has a narrower beam and a higher resolution than does Doppler radar. ' Today, in an attempt to obtain tornado wind information at fairly close range (less than 10 km), smaller portable Doppler radar units are peering into tornado generating ' storms. During the 1990s, the National Weather Service plans to install a network of Doppler radar units at selected weather stations. This planned radar network, called NEXRAD [an acronym for NEXt Generation Weather RADar) will replace the aging ' conventional radar units. Detecting the signatures of mesocylones and tornadoes with Doppler radar will assist forecasters in determining which severe thunderstorms will likely spawn tornadoes. In addition, they should give advanced and improved warning ' of an approaching tornado. More reliable warnings, of course, should cut down on the number of false alarms. ' Because the Doppler radar shows air motions within a storm, it can help to identify the magnitude of other severe weather phenomena, such as gust fronts, micro bursts, and wind shears that are dangerous to aircraft. Certainly, as Doppler radar becomes part of ' the major radar network, our understanding of the processes that generate severe thunderstorms will be enhanced, and hopefully there will be an even better tornado and severe storm -warning system, resulting in fewer deaths and injuries. ' WATERSPOUTS A waterspout is a rotating column of air over a large body of water. The waterspout ' may be a tornado that formed over land and then traveled over water. In such a case, the waterspout is called a tornadic waterspout. Waterspouts that form over water, especially above the warm, shallow coastal waters of the Florida Keys, where almost ' 100 occur each month during the summer, are referred to as "fair weather" waterspouts. These waterspouts are generally much smaller than an average tornado, as they have diameters usually between 3 and 100 m. Fair weather waterspouts are ' also less intense, as their rotating winds are typically less than 45 knots. In addition, they tend to move more slowly than tornadoes and they only last for about 10 to 15 minutes, although some have existed for up to one hour. Fair weather waterspouts tend to form when the air is unstable and clouds are developing. Unlike the tornado, they do not need a severe thunderstorm to generate ' them. Some form with small thunderstorms, but most form with developing cumulus congestus clouds whose tops are frequently no higher than 3600 m (12,000 ft) and do not extend to the freezing level. Apparently, the warm, humid air near the water helps ' Town of Kill Devil Hills and William C. Schmidt Page 8-19 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report: ' Hazard Identification and Evaluation to create atmospheric instability, and the updraft beneath the resulting cloud helps initiate uplift of the surface air. Recent studies even suggest that gust fronts and converging sea breezes may play a role in the formation of some of the waterspouts that form over the Florida Keys. The waterspout funnel is similar to the tornado funnel in that both are clouds of condensed water vapor with converging winds that rise about a central core. Contrary to popular belief, the waterspout does not draw water up into its core; however, swirling spray may be lifted several meters when the waterspout funnel touches the water. Apparently, the most destructive waterspouts are those that begin as tornadoes over land, then move over water. A photograph of a particularly well -developed and intense fair weather waterspout near the Florida Keys is shown in Fig. 16.33. Town of Kill Devil Hills and William C. Schmidt �I Page 8-20 ' Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report. Hazard Identification and Evaluation Northeasters (Extra Tropical Winter Storms) In addition to the hurricane threat, North Carolina experiences in the winter and early spring a progression of extra -tropical cyclones, generally moving from west to east across the middle latitudes. ' These storms are an entirely different and a more frequent weather pattern which can cause dangerous conditions along some sections of the coast from Maine to Cape ' Hatteras. Unlike hurricanes, which pass over a coastal community in several hours, a northeaster may last in an area for several days. Precipitation may or may not be associated with these storms. Although minimum hurricane force winds (74 mph) are only occasionally exceeded, the massive size of the storms can create substantial coastal hazards. At any one time, it may cover more than 1000 continuous miles of the North Atlantic waters. Northeasters may remain practically stationary for more than a week over the same area of the ocean. ' Their primary impact comes from the force exerted on the water surface by continuous high winds. This generates intensive and heightened wave action, which increases beach erosion. An extreme northeaster may even generate a storm surge, causing extensive flooding and bringing wave action inland. While the storm surge accompanying hurricanes generally recedes after one or two high tides, the surge from a persistent northeaster may last for four or five successive high tides. The highest tides and strongest winds in a northeaster occur farther from the storm's low pressure center than in a hurricane; thus a northeaster can cause widespread damage even though its center is several hundred miles at sea. ' The Dolan/Davis Northeaster Classification System j I The Dolan/Davis Northeaster Classification of Atlantic Coast winter storms is based on measurements of storm locations, tracks, fetches, durations, and wave heights. Data for the system consisted of 1,347 northeast storms that produced at least a significant deep -water wave height of 5.0 feet (1.5 m) at Cape Hatteras, North Carolina. This threshold was used to define-anortheast storm and to calculate its duration based on confirmed field evidence that a 5 foot (1.5 m) deep -water wave will result in measurable beach face erosion along the North Carolina coast. The data spanned the period 1942 to 1984 (Bosserman and Dolan, 1968; Dolan et al, 1988). Whenever possible, wave height and duration data was verified through comparisons with measured wave records obtained from NOAA buoys and ship observations positioned in the fetch areas. In developing the system, 1,347 storms were classified in terms of significant wave heights (H 1/2) and durations. Together, these data can be used as an estimate of the relative storm power, which is defined as H 1/2 times duration. While a more exacting calculation of wave power could be developed, Dolan Davis generally did not obtain wave period data in their hind -casting. Town of Kill Devil Hills and William C. Schmidt Page 8-21 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report. ' Hazard Identification and Evaluation Northeast Storm Scale (Halsey) Class 1: (up to 1 tide) Beach erosion and dunes sustain some scarping. Class 2: (up to 2 tides) Besides heavy beach erosion, dunes moderately to significantly scarped: overwash in weak areas, especially down street ends: sections t of unprotected boardwalks popped or lifted off, flooding begins. Class 3: (2 to 3 tides) Serious beach erosion: dunes not only scarped, but some areas ' flattened by overwash; flooding serious; widespread boardwalk damage. Class 4: (3 to 4 tides) Erosion reaching to marsh "basement" in some areas; most ' manmade dunes flattened; significant overwash; fans coalescing; deeper flooding widespread; breaching in natural dunes increasing. Class 5: (4 to 5 tides) Surge platforms and incipient inlets present; washover sands ' completely clog low-lying islands and roads, natural dunes heavily eroded. Northeasters Affecting Coastal North Carolina , Many northeaster storms have affected North Carolina in the Twentieth Century. The Ash Wednesday Storm - March 7, 1962 - caused extensive damage in Dare County. It was a Class 5 northeaster with a storm surge and waves totaling over 20 feet above mean sea level. Roads were washed out, and a 20 foot wide inlet was cut across Hatteras Island at Buxton. This was filled by dredges several months later at considerable expense. On some parts of the Delmarva Peninsula (to the north), this ' was the most damaging of all coastal storms, including hurricanes on record to date. Town of Kill Devil Hills and William C. Schmidt I Page 8-22 ' ' Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report., Hazard Identification and Evaluation Effects of Storms ' Prologue ' The North Carolina coast faces a strong threat of damages from hurricanes, northeasters, and other major storms. While there has been a marked lull in the number of hurricanes that have stricken the North Carolina coast in the past 20 years, ' the threat still exists; many say that North Carolina is long overdue for a major storm. At the same time, development along the coast has grown by leaps and bounds. Unless this development is wisely located and built to withstand hurricane forces, North Carolina's coastal communities will face massive destruction. Local governments, as ' the primary protectors of the public health, safety, and general welfare, have a responsibility to reduce the risk of property damages and loss of life attending coastal development. They also have a responsibility to ensure that reconstruction following a ' major storm can occur quickly and leave the community safer from disaster in the future. These are the goals of hazard mitigation and reconstruction planning. ' The first important step in the design and construction of a storm -resistant residence is to determine the types and magnitudes of natural hazards that are likely to occur near the site. These conditions often result in substantial changes in the land forms on the ' site, in many instances making the lot nearly unrecognizable during and after the storm. Good design must begin with a reasonable understanding of the magnitude of the environmental hazards as well as the changes that are likely to occur on your lot ' and on those nearby. IMPACTS AND COMPONENTS OF A HURRICANE ' The two most drastic effects of hurricanes are fatalities and property damage. Since the turn of the century, the general trend has been toward a reduction in the number of ' deaths from hurricanes but an exponential increase in the amount of property damage. Figure 2.3 illustrates these trends to 1970. The main reason for the reduction and stabilization in death rate has been a ' combination of improvements in monitoring and warning systems and local preparedness and evacuation planning. However, as the population continues to grow in coastal areas beyond the point of safe evacuation within the available warning time, ' the potential for substantial loss of human life remains. While hurricane fatalities have decreased since 1900, the increase in property ' damages is staggering. This increase in damages parallels the increase in population and development in coastal hurricane -prone areas since World War II. Property damages stem mainly from riverine flooding, storm surge flooding, and the waves ' which ride on top of the surge. They also stem from erosion beneath structures built too near the water, and from high winds, which can affect a very large area. ' Town of Kill Devil Hills and William C. Schmidt Page 8-23 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report. ' Hazard Identification and Evaluation The aforementioned hurricane characteristics and forces described above create a ' number of different forces on buildings and facilities and these are briefly reviewed below. , Air Generated Forces Applied to Buildings Two primary types of wind forces depicted are: direct and suction (or negative), each , working either laterally (horizontally or sideways) or on roof and floor systems. Direct lateral forces, for example, are those that act on windward (the direction from which the ' wind is coming) vertical surfaces, such as wall or piles. Negative or suction lateral forces act on the leeward (the direction toward which the wind is blowing) side of vertical surfaces, and also on surfaces which are parallel to the direction of air flow. Forces are also exerted against interior walls as a result of rapid drops in outside air , pressure. Wind forces can also lead to the destruction of certain public facilities and ' infrastructure. Hurricane winds typically damage power and telephone lines. Hurricane Diana which struck the North Carolina coast in 1984 resulted in the destruction of the public water tower in Carolina Beach, as a further example. ' Water Forces Water forces include both hydrostatic forces (caused by the pressure of still water bearing against one side of a surface) and hydrodynamic forces (caused by the movement of flowing water pushing against or flowing around a surface). Other forces ' include the battering-ram effects that may be exerted by water -borne debris, and the scour and erosion which can result in the undermining of building foundations. Water forces created by hurricanes and coastal storms also wreak havoc on certain , public facilities and infrastructures. Roads and highways can experience severe erosion and scouring for instance. Public sewer and water lines can also be destroyed or damaged from flooding. ' Hurricane Tracks I Selected tracks of major hurricanes affecting North Carolina since 1871 are shown in figures 2 and 3. These are segregated into hurricanes approaching from the southeast ' and southwest quadrants, respectively. Tracks of hurricanes bypassing the coast in recent years are also included. ' A few hurricanes strike the Atlantic coast north of Cape Hatteras from the northeast. The tracks of tropical storms and hurricanes that moved from the northeast in the general region of the study area, are shown in figure 4. The information on hurricane tracks is taken from the charts of North Atlantic tropical cyclones compiled by Cry (1965). For 1964 through 1974, similar tracks are published in the Monthly Weather Review. I Town of Kill Devil Hills and William C. Schmidt Page 8-24 ' Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report. Hazard Identification and Evaluation Historical Notes on Hurricanes ' Brief notes on the history of hurricanes and damages caused by them are abstracted from published papers. Wind speeds are included to indicate the intensity of storms. Wind speeds from Weather Bureau stations from storms before 1920's have been adjusted by the instrumental corrections to anemometers developed at that time (Harrison 1963). Since that time, official wind reports include the corrections. Prior to 1940, the highest wind given for a storm was usually the "maximum velocity," an ' average wind speed for a five minute period. In recent years, the highest sustained wind is an average over a one -minute period. For a complete chronology of tropical cyclones since 1586, the reader is referred to the publication on "North Carolina Hurricanes" (Hardy and Carney 1962). ' September 4, 1815 ' A major hurricane cut across extreme eastern North Carolina in early September 1815. This hurricane moved inland on the morning of September 4, passing close to New Bern, N. C., on the Neuse River and recurved northeastward. At Beaufort, N. C., ' the tide flowed 4 ft higher than ever known. Every one of the more than 20 vessels at Ocracoke Inlet, along the Outer Banks of North Carolina, was driven ashore by the shifting gale. In New Bern, the tide was one foot higher than in any storm since 1795 and reached an elevation of nearly 12 ft above common high-water mark (Ludlum ' 1963). tJune 3-4, 1825 This early season tropical cyclone swept up the Atlantic coast with reports of major ' damage all the way from Florida to New York City. Very high winds, which lasted 30 hours, were reported by the post surgeon of Fort Johnston at Cape Fear, N.C. Along the Outer Banks of North Carolina the hurricane lashed at shipping settlements. Near Ocracoke Inlet, 25 vessels were driven ashore. A press dispatch from Adam's Creek, ' N.C., near Cape Lookout reported very heavy losses with crops destroyed and cattle drowned as the storm tide rose 14 ft above low water. At New Bern, the tide rose 6 ft ' and considerable damages near the water front were reported (Ludlum 1963). August 25, 1827 ' This hurricane was traced to its origin in the Windward Islands on August 17. It struck the coast between Cape Fear and Cape Hatteras on August 25. Ludlum (1963) gives some descriptive accounts of the storm tides along this stretch of the coast: "The towns ' of New Bern and Washington, both heads of navigation for tidal rivers emptying into Pamlico Sound, suffered severely from high tides, and such high waters, too, are always caused by wind with an easterly component. At Washington the tide was 12 to ' 15 ft above ordinary tides and houses on Water Street found the river 5 to 6 ft deep in their first floor during the height of the storm tide. For a period of time at New Bern, all communication was by canoe. Near Cape Hatteras, two New York -to -North Carolina ' packets were driven ashore and smashed to pieces by the tremendous breakers. The new Cape Hatteras Lightship off Ocracoke Inlet broke loose and piled up on the south side of Ocracoke Island." ' Town of Kill Devil Hills and William C. Schmidt Page 8-25 ' Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report. Hazard Identification and Evaluation July 12-15, 1842 A very destructive hurricane swept the entire North Carolina coast, apparently most ' severe in the Ocracoke - Portsmouth, N.C., area. This storm was reported to have been the most violent experienced at Ocracoke Bar for 80 years (another great hurricane in 1761 changed much of the coast -line of the Outer Banks and cut through the New Inlet ' near Wilmington, N.C.). The damage along the Outer Banks was immense. The entire village on Portsmouth Island near Ocracoke Inlet, with the exception of one building, was wrecked. A store at the settlement was blown down and floated away at the height t of the storm. Fourteen vessels went aground on the ocean beach near Ocracoke Inlet and fourteen more on the inside beaches. Two unknown vessels were dashed to pieces in the breakers on Diamond Shoals. A number of dead horses and cattle were ' seen drifting down the Sound after the storm was over (Ludlum 1963). September 7-8, 1846 ' This hurricane apparently approaching slowly from the south opened up two new inlets of major commercial importance across the Outer banks. To the south of Cape ' Hatteras, a new Hatteras Inlet between Ocracoke and Hatteras Islands provided a new entrance into Pamlico Sound. To the north, Oregon Inlet (named after the first ship to pass through) split Bodie Island below Nags Head for a more direct route to Albemarle ' Sound ports. The hurricane caught 20 ships at Ocracoke Inlet and drove all but two of them ashore or out to sea. The small community of Hatteras just south of the Cape had all but six houses flattened by the storm. At Nags Head the tide rose about 9 ft higher than common tide (Ludlum 1963). October 23, 1878 ' This hurricane moved northward across Cuba, skirted the east coast of Florida and moved inland between Wilmington and Morehead City, N.C., on October 23rd. It struck ' the Outer Banks with full hurricane force, with maximum winds of 77 mph recorded at Cape Lookout and 63 mph at Portsmouth. The steamer City of Houston was lost on Frying Pan Shoals; a great many ships were damaged or lost in the storm all along the ' Atlantic coast (Hardy and Carney 1962). August 18, 1879 ' A severe hurricane moved inland near Wilmington on the 18th and back out to sea near Norfolk with highest winds reported at Cape Lookout. The anemometer cups at Cape Lookout were blown away and the wind was afterward estimated to have ' reached 127 mph. Anemometers were also destroyed at Hatteras, Fort Macon, Kitty Hawk, Portsmouth, N.C., and Cape Henry, Va., with speeds estimated at 100 mph or more. A ship report indicated waves forty feet from trough to crest. This storm was most ' destructive in the Morehead City - Beaufort, N.C., area where two hotels were destroyed and 1,000 ft of railroad track torn up. All the wharves were washed away and the chimneys of most houses were blown away. On the Outer Banks, the storm ' caused great damage at Diamond City, which was near Cape Lookout (Hardy and Carney 1962). ' Town of Kill Devil Hills and William C. Schmidt Page 8-26 0 F Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report: Hazard Identification and Evaluation August 17-18, 1899 One of the most severe hurricanes on record for the Hatteras area moved slowly northward across the Outer Banks during August 17-18. By early morning of the 17th, the wind was blowing from the northeast at 54 mph at Hatteras; it had reached 71 mph at 1:00 p.m. with extreme velocities of 90 to 105 mph. The anemometer then blew away; stronger winds probably occurred. Hatteras reported a barometer reading of 968.9 mb (28.61 in) at 8:00 p.m. of the same day (U. S. Weather Bureau 1899). The Weather Bureau observer at Hatteras reported that "the entire island" was covered with water to a depth of 4 to 10 ft. There were not more than four houses in which the tide did not rise to a depth of 1 to 4 ft. All fishing piers and equipment were destroyed; all bridges were swept away; a great proportion of the homes on the island were damaged. There was much destruction at Diamond City, N.C. Flooding of much of the coastal areas and strong winds and heavy rains inland as far as Raleigh did great damage to crops (Hardy and Carney 1962). July 31, 1908 This storm had its inception as a tropical storm off the east coast of Florida. It then moved to the east-northeast, did a complete "loop" and became a hurricane as it moved northeastward off the coasts of Georgia and the Carolinas. It moved inland near Cape Lookout on July 31 then across Pamlico Sound, continuing its northeastward movement. Highest reported wind was 46 mph at Hatteras, but the storm piled up considerable water on the North Carolina coast south of Hatteras. This combined with torrential downpours (10.73 inches in 72 hours at New Bern and 9 inches at Kinston) caused much flooding in the eastern counties. Damage was "immense," but no injuries or fatalities were recorded. At New Bern, this was "the worst storm in history" (Hardy and Carney 1962; Corps of Engineers, Wilmington, N.C. 1961; and Sugg, et al., 1971). September 16, 1933 This hurricane formed east of the Leeward Islands, moved northwest and then northward, increasing in intensity and striking the coast a little west of Hatteras about 8 a.m. on the 16th. Maximum wind speed at Hatteras was estimated at 76 mph because a portion of the anemometer was blown away. Winds were estimated up to 125 mph in New Bern and Beaufort. Minimum barometric pressure at Hatteras was 957 mb. Damage was heavy from a short distance south of New Bern to the Virginia line. It was reported that hardly a building was left standing in several coastal towns. High winds, waves, and piling up of water in Pamlico and Albemarle Sounds caused 21 deaths. Wind and water did great damage at New Bern where water was reported to reach "a height of 3 to 4 ft" (Hardy and Carney 1962). An estimated high tide of 7.0 ft MSL occurred at Ocracoke, N.C. (Corps of Engineers, Wilmington, N.C. 1963). Town of Kill Devil Hills and William C. Schmidt Page 8-27 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report: , Hazard Identification and Evaluation September 18, 1936 This hurricane was one of the most severe hurricanes on record at Hatteras. Maximum winds of 80 mph from the northwest were reported at Hatteras and 90 mph at Manteo, N.C. As the hurricane approached Hatteras it began recurving northward and the storm center passed close to the station on the coast. The highway from Currituck, N.C., to Norfolk, Va., was washed out. About 35 ft of beach was cut away at Nags Head, N.C. Tides were very high at Manteo and Hatteras (Hardy and Carney 1962). A high tide of 6.0 ft MSL was reported at Hatteras and an estimated 6. 3 ft MSL at Ocracoke, N.C. (Corps of Engineers, Wilmington, N.C. 1963). September 14, 1944 The "Great Atlantic Hurricane" of September 1944 caused destruction to 900 miles of the Atlantic coast from Hatteras northward. The center of the hurricane passed a short distance to the east of Hatteras with estimated maximum winds of 110 mph. At Hatteras a lowest barometric pressure of 947.2 mb (27.97 in) was recorded, the lowest pressure reading on record at the station. Cape Henry, Va., reported maximum winds of 134 mph with gusts estimated at 150 mph (Sumner 1944). There was heavy damage in Elizabeth City, N.C., and the Nags Head area. The storm was very severe and caused considerable property damage on Ocracoke Island. Local residents reported the highest tide on record at Ocracoke Village, 7.5 ft MSL (Corps of Engineers, Wilmington, N.C. 1963). A highest tide of 7.0 ft above mean low water (6.0 ft MSL) was reported by the U.S. Weather Bureau at Hatteras, N.C. (Sumner 1944). August 12, 1955 - Connie Hurricane Connie entered the North Carolina coast close to Cape Lookout about 8:30 a.m. on August 12. The prolonged pounding of high waves against the coast caused tremendous beach erosion estimated to have been worse than that caused by Hazel in 1954. Tides of about 4.0 ft MSL were reported at Ocracoke and Hatteras, N.C. (Corps of Engineers, Wilmington, N.C. 1963), while water in the sounds and near the mouths of rivers were 5 to 7 ft MSL (Harris 1963). At Fort Macon, N.C., winds of 75 mph with peak gusts of 100 mph and lowest pressure of 962 mb were reported. The storm also brought torrential rains with the maximum, ranging around 12 inches within 48 hrs of falling near Morehead City. Total damage throughout the state was estimated at $50 million (Hardy and Carney 1962). September 19, 1955 - lone Hurricane lone, moving from the south, crossed the North Carolina coast near Salter Path, about 10 miles west of Morehead City, about 5 a.m. on September 19. It then slowly curved to the northeast, passing out to sea near the Virginia state line early on September 20. When lone entered North Carolina, highest winds were a little over 100 mph in gusts. The highest recorded wind speed was 75 mph gusting to 107 mph at Cherry Point. Minimum barometric pressure over North Carolina was 960 mb. Heavy rains accompanied lone. At the same time, prolonged easterly winds drove tide water onto the beaches and into the sounds and their estuaries to a height of 3 to 10 ft above normal. The result was inundation of the greatest area of eastern North Carolina ever n 0 L Town of Kill Devil Hills and William C. Schmidt Page 8-28 ' Storm Hazard Mitigation and Post -Disaster Reconstruction Plan 8. Supplemental Report., Hazard Identification and Evaluation known to have been flooded. At New Bern, the depth of water was the greatest on record, being about 10.5 ft above mean low water, with 40 city blocks flooded. Several hundred homes were washed away and thousands were flooded by water with depths ranging up to 4 ft (Hardy and Carney 1962). A high tide of 7.2 ft MSL was reported at Atlantic Beach, N.C. (Harris 1963). High tides of 5.7 and 3.8 ft MSL at Ocracoke and Hatteras, N.C., respectively, were reported by the Corps of Engineers (Corps of Engineers, Wilmington, N.C. 1963). September 27, 1958 - Helene Hurricane Helene was one of the most powerful storms of recent history and, fortunately for North Carolina, the storm center moved up the coast staying well out at sea, on September 26-27. Even so, the highest winds of record were recorded at Wilmington, with peak gusts of 135 mph and fastest mile 85 mph. The lowest reported central pressure was 932 mb at a point south-southeast of Cape Fear early on the morning of the 27th (aircraft reconnaissance). There was some beach erosion due to seas and tides but this was minimized by the passage of the storm at time of low astronomical tide. The highest tides on ocean beaches were estimated at 3 to 5 ft above normal. Tides were higher on the southern edge of Pamlico Sound, where a sudden rise following the wind shift as the center passed brought the tides to 7 or 8 ft above normal (Hardy and Carney 1962). At Ocracoke, N.C., local residents stated it was the most severe storm since 1944. Water covered most of the island and swept into about 25 homes in the village. The northern end of the island was breached at six different locations during the storm. Over 2.5 miles of state highway steel -mat pavement was washed out, and approximately 12 miles of National Park Service sand fence located near the ocean shore was destroyed. High-water mark of 5.5 ft MSL was reported by local residents in the village of Ocracoke. A high tide of 5.1 ft MSL was recorded at Hatteras, N.C. (Corps of Engineers, Wilmington, N.C. 1963). September 11, 1960 - Donna Hurricane Donna passed inland over the North Carolina coast between Wilmington and Morehead City on September 11. The center of the storm passed a few miles east of Wrightsville Beach, although Wilmington and Wrightsville Beach were in the "eye" for about an hour. Lowest barometric pressure at Wilmington was 962 mb. Tides of 6 to 8 ft above normal combined with high winds caused severe damage at many points. Maximum winds were of hurricane force with Wilmington reporting a peak gust of 97 mph. The storm center moved northward along a path slightly east of a line from Wilmington to Norfolk during the night of the 11 th. Coastal communities suffered heavy structural damage from Wilmington to Nags Head, with considerable beach erosion. Wind gusts were in excess of 100 mph and tides were 4 to 8 ft above normal (Hardy and Carney 1962). High tides of 10.6 ft MSL were reported at Atlantic Beach, N.C., and 4 to 6 ft MSL in the sounds and near the mouths of rivers. Tides of 3 to 4 ft MSL were reported on the Outer Banks near Hatteras (Harris 1963). Town of Kill Devil Hills and William C. Schmidt Page 8-29 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan September 30 - October 1, 1971 - Ginger 8. Supplemental Report. , Hazard Identification and Evaluation Ginger will be noted chiefly for its longevity and circuitous track. This storm was tracked for 31 days during 20 of which it was a hurricane. On September 27, Ginger moved northwestward and set a steady course toward the North Carolina coast. Its center crossed the coast near Morehead City on the evening of September 30 with maximum sustained winds of 75 mph and minimum central pressure of 993 mb. Total damage caused by the storm in North Carolina is estimated at $10 million. Tides on Pamlico Sound were 4-7 ft above normal. At Washington, Aurora, New Bern, and Cherry Point, N.C., tides were 6 ft above normal. On the ocean beaches at Hatteras, tides were 2-3 ft above normal (Simpson and Hope 1972). February 17, 1973 One of the most damaging winter coastal storms of the present generation was on February 17, 1973. The following newspaper quote succinctly describes the storm: "North Carolina's land mass is smaller by several hundred acres this week as a result of a severe coastal storm which gnawed away at beaches from Corolla to Cape Fear. "During the two days following a freak storm that frosted the. state's eastern lowlands with up to 15 inches of snow, savage 56-knot winds and powerful 40-foot waves hauled tons of sand from the shore. "The wind -whipped sea toppled large buildings in resort communities on the Outer Banks, nearly bisected at least two offshore islands, ripped up highways, filled roadbeds with sand and carved away large chunks of sandy beach. "The worst of the storm's fury was directed at Buxton, Kitty Hawk and Nags Head, but severe erosion and some property damage occurred at the more southerly resort communities of Wrightsville Beach, Carolina Beach and Topsail Beach." (Raleigh News and Observer February 19, 1973). A typical description of local damage, from the same source, is "At Kitty Hawk four beach cottages were washed away, nine were toppled by the waves but left partially standing, 12 others received structural damage from the pounding surf and dozens of others are left standing so near the encroaching sea that another storm would undermine them." October, 1991 The Halloween Storm of 1991, a Category 5 northeaster, damaged or destroyed dozens of beach cottages by wave and storm surge, flooded miles of road and eroded beaches and frontal dunes.

Supp. No. 5 479 § 8-1 KILL DEVIL HILLS TOWN CODE Base flood means the flood having a one percent chance of being equaled or exceeded in any given year. Basement means that lowest level or story which has its floor subgrade on all sides. Breakaway wall means a wall that is not part of the structural support of the building and is intended through its design and construction to collapse under specific lateral loading forces without causing damage to the elevated portion of the building or the supporting foundation system. A breakaway wall shall have a design safe loading resistance of not less than ten (10) and no more than twenty (20) pounds per square foot. A wall with loading resistance of more than twenty (20) pounds per square foot requires a professional engineer or architect's certif- icate. Building means any structure built for support, shelter, or enclosure for any occupancy or storage. Coastal High Hazard Area means an area of special flood hazard extending from offshore to the inland limit of a primary frontal dune along an open coast and any other area subject to high velocity wave action from storms or seismic sources. Development means any man-made change to improved or unimproved real estate, in- cluding, but not limited to, buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations, or storage of equipment or materials Elevated building means a nonbasement building (a) built, in the case of a building in zones Al through A30, AE, A99, AO, AH, B, C, or X to have the top of the elevated floor, or in the case of a building in zones VI—V30, VE or V to have the bottom of the lowest horizontal structural member of the elevated floor above the ground by means of pilings, columns (posts and piers), shear walls parallel to the flow of water and, (b) adequately anchored so as not to impair the structural integrity of the building during a flood up to the magnitude of the base flood. In the case of zones Al through A30, AE, A, A99, AO, AH, B, C, and X, "elevated building" also includes a building elevated by means of fill or solid foundation perimeter walls with openings sufficient to facilitate the unimpeded movement of floodwaters. In the case of zones Vl through V30, VE, or V, "elevated building" also includes a building otherwise meeting the definition of "elevated building", even though the area below is enclosed by -means of breakaway walls if the breakaway walls meet the standards of section 8-41(5) of this chapter. Existing manufactured home park or manufactured home subdivision means a manufac- tured home park or subdivision for which the construction of facilities for serving the lots on which the manufactured homes are to be affixed including, at a minimum, the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads is completed before the effective date of this chapter. Expansion to an existing manufactured home pariz or subdivision means the preparation of the additional sites by the construction of facilities for servicing the lots on which the manu- Supp. No. 5 480 FLOOD DAMAGE PREVENTION § 8-1 (3) Designed to be self-propelled or permanently towable by a light duty truck; and ' (4) Designed primarily not for use as a permanent dwelling, but as temporary living quarters for recreational, camping; travel, or seasonal use. ' Reference feature is the receding edge of a bluff or eroding frontal dune or, if such a feature is not present the normal highwater line or the seaward line of vegetation if highwater line cannot be identified. F Remedy a violation means to bring the structure or other development into compliance with state or local floodplain management regulations, or, if this is not possible, to reduce the impacts of its noncompliance. Ways that impacts may be reduced include protecting the struc- ture or other affected development from flood damages, implementing the enforcement provi- sions of the ordinance or otherwise deterring future similar violations, or reducing federal financial exposure with regard to the structure or other development. Sixty year setback means a distance equal to sixty (60) times the average annual long-term recession rate at a site, measured from the reference feature. Start of construction (for other than new construction or substantial improvements under the Coastal Barrier Resources Act (P.L. 97-348), includes substantial improvement, and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, rehabilitation, addition, or improvement was within one hundred eighty (180) days of the permit date. The actual start means the first placement of permanent construction of a structure (including a manufactured home) on a site, such as the pouring of slabs or footings, installation of piles, construction of columns, or any work beyond the stage of exca- vation or the placement of a manufactured home on a foundation. Permanent construction does not.include land preparation, such as clearing, grading, and filling; nor does it include the installation of streets and/or walkways; nor does it include excavation for a basement, footings, piers or foundations, or the erection of temporary forms; nor does it include the installation on the property of accessory buildings, such as garages or sheds not occupied as dwelling units or not part of the main structure. For a substantial improvement, the actual start of construction means the first alteration of any wall, ceiling, floor, or other structural part of the building, whether or not that alteration affects the external dimensions of the building. Structure means, for floodplain management purposes, a walled and roofed building, a -manufactured home, including a gas or liquid storage tank, or other man-made facilities or infrastructures that are principally above ground. Substantial damage means damage of any origin sustained by a structure whereby the cost of restoring the structure to its before -damaged condition would equal or exceed fifty (50) percent of the market value of the structure before the damage occurred. See definition of "substantial improvement." Substantial improvement" means any repair, reconstruction, rehabilitation, addition, or other improvement of a structure, the cost of which equals or exceeds fifty (50) percent of the market value of the structure before the "start of construction" of the improvement. This term Supp. No. 5 483 1 § 8-1 HILL DEVIL HILLS TOWN CODE includes structures which have incurred "substantial damage," regardless of the actual repair work performed. The term does not, however, include either: (1) Any project of improvement of a structure to correct existing violations of state or local health, sanitary, or safety code specifications which have been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions; or (2) Any alteration of a historic structure, provided that the alteration will not preclude the structure's continued designation as a historic structure. Substantially improved existing manufactured home park or subdivision means where the repair, reconstruction, rehabilitation or improvement of the streets, utilities and pads equals or exceeds fifty (50) percent of the value of the streets, utilities and pads before the repair, reconstruction, or improvement commenced. Variance is a grant of relief to a person from the requirements of this chapter which permits construction in a manner otherwise prohibited by this chapter where specific enforce- ment would result in unnecessary hardship. Violation means the failure of a structure or other development to be fully compliant with the community's floodplain management regulations. A structure or other development without the elevation certificate, other certifications, or other evidence of compliance required in this -chapter is presumed to be in violation until such time as that documentation is provided. Zone of imminent collapse means an area subject to erosion adjacent to -the shoreline of an ocean, bay or lake and within a distance equal to ten (10) feet, plus five (5) times the average annual long term erosion rate for the site, measured from the reference feature.

' The legislature of the State of North Carolina has, in Part 6, Article 21 of Chapter 143; Parts 3, 5, and 8 of Article 19 of Chapter 160A; and Article 8 of Chapter 160A of the North Carolina General Statutes, delegated the responsibility to local governmental units to adopt Supp. No. 5 485 § 8-20 HILL DEVIL HILLS TOWN CODE regulations designed to promote the public health, Safety, and general welfare of its citizenry. Therefore, the board of commissioners does ordain as follows in this chapter. (Ord. No. 93-03, 3-8-93) Sec. 8-21. Findings of fact. (a) The flood hazard areas of the town are subject to periodic inundation which results in loss of life, property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures of flood protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety, and general welfare. (b) These flood losses are caused by the cumulative effect of obstructions in floodplains causing increases in flood heights and velocities, and by the occupancy in flood hazard areas by uses vulnerable to floods or hazardous to other lands which are inadequately elevated, floodproofed, or otherwise unprotected from flood damage. (Ord. No. 93-03, 3-8-93) Sec. 8.22. Statement of purpose. It is the purpose of this chapter to promote the public health, safety, and general welfare and to minimize public and private losses due to flood conditions in specific areas by provisions designed to: (1) Restrict or prohibit uses which are dangerous to health, safety, and property due to water or erosion hazards, or which result in damaging increases in erosion or in flood heights or velocities; (2) Require that uses vulnerable to floods, including facilities which serve such uses, be' protected against flood damage at the time of initial construction; (3) Control the alteration of natural floodplains, stream channels, and natural protective barriers which are involved in the accommodation of floodwaters; (4) Control filling, grading, dredging, and other development which may increase erosion or flood damage; and (5) Prevent or regulate the construction of flood barriers which will unnaturally divert floodwaters or which may increase flood hazards to other lands.. (Ord. No. 93-03, 3-8-93) Sec. 8-23. Objectives. The objectives of this chapter are to: (1) Protect human life and health; (2) Minimize expenditure of public money for costly flood control projects; (3) Minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public; Supp. No. 5 486 LI i 0 I V FLOOD DAMAGE PREVENTION (4) Minimize prolonged business interruptions; § 8-32 (5) Minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, streets, and bridges located in floodplains; (6) Help maintain a stable tax base by providing for the sound use and development of flood -prone areas in such a manner as to minimize flood blight areas; and (7) Ensure that potential home buyers are notified that property is in a flood area.

Located within areas of special flood hazard established in section 8-3, are areas designated as floodways. The floodway is an extremely hazardous area due to the velocity of floodwaters which carry debris and potential projectiles and has ero- sion potential. The following provisions shall apply within such areas: a. No encroachments, including fill, new construction, substantial improvements and other developments shall be permitted unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with stan- dard engineering practice that the proposed encroachment would not result in any increase in the flood levels during the occurrence of the base flood. Such certification and technical data shall be presented to the local administrator. b. If section 8-41(6)a is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of article IV. c.

These areas have special flood hazards associated with wave wash. The following provisions shall apply within such areas: a. All buildings or structures shall be located landward of the first line of stable natural vegetation and comply with all applicable CAMA setback requirements. b. All buildings or structures shall be elevated so that the bottom of the lowest supporting horizontal member (excluding pilings or columns) is located no lower than the base flood elevation level, with all space below the lowest supporting Supp. No. 5 496 Supp. No. 5 FLOOD DAMAGE PREVENTION § 8-41 member open so as not to impede the flow of water. Open lattice work or deco- rative screening may be permitted for aesthetic purposes only and must be de- signed to wash away in the event of abnormal wave action in accordance with section 8-41(5)h. c. All buildings or structures shall be securely anchored on pilings or columns. d. All pilings and columns and the attached structures shall be anchored to resist flotation, collapse, and lateral movement due to the effect of wind and water loads acting simultaneously on all building components. e. A registered professional engineer or architect shall certify that the design, spec- ifications and plans for construction are in compliance with the provisions con- tained in section 8-41(5)b., c., and d. of this chapter. f. There shall be no fill used as structural support. Noncompacted fill may be used around the perimeter of a building for landscaping/aesthetic purposes provided the fill will wash out from storm surge, thereby rendering the building free of obstruction prior to generating excessive loading forces, ramping effects, or wave deflection. The local administrator shall approve design plans for landscaping/ aesthetic fill only after the applicant has provided an analysis by an engineer, architect, and/or soil scientist which demonstrates that the following factors have been fully considered: 1. Particle composition of fill material does not have a tendency for excessive natural compaction; 2. Volume and distribution of fill will not cause wave deflection to adjacent properties; **and 3. Slope of fill will not cause wave run-up or ramping. g. There shall be no alteration of sand dunes'or mangrove stands which would increase potential flood damage. h. Lattice work or decorative screening shall be allowed below the base flood ele- vation provided they are not part of the structural support of the building and are designed so as to breakaway, under abnormally high tides or wave action, without damage to the structural integrity of the building on which they are to be used and provided the following design specifications are met: 1. No solid walls shall be allowed. 2. Material shall consist of wood or mesh screening only. 3. Design safe loading resistance of each wall shall be not less than ten (10) nor more than twenty (20) pounds per square foot; or 4.

' .0209 ESiUARiNE SHORELiNES (a) Rationale. As an AEC, estuarine shorelines, although characterized as dry land, are considered a component of the estuarine system because of tine close association with the adjacent estuarine waters. ' This Section defines estuarine shorelines, describes the significance, and articulates standards for devel- opment.

' (c) Significance. Development within estuarine shorelines influences the quality of estuarine life and is subject to the damaging processes of shore front erosion and flooding. (d) Management Objective. To ensure shoreline development is compatible with both the dynamic ' nature of estuarine shorelines and the values of the estuarine system. (e) Use Standards (1) All development projects, proposals, and designs shall substantially preserve and not weaken or eliminate natural barriers to erosion, including, but not limited to, peat marshland, resistant clay ' shorelines, and cypress -guru protective fringe areas adjacent to vulnerable shorelines. (2) All development projects, proposals, and designs shall limit the construction of impervious sur- faces and areas not allowing natural drainage to only so much as is necessary to adequately service the major purpose or use for which the lot is to be developed. Impervious surfaces shall ' not exceed 30 percent of the AEC area of the lot, unless the applicant can effectively demon- strate, through innovative design, that the protection provided by the design would be equal to or exceed the protection by the 30 percent limitation. Redevelopment of areas exceeding the ' 30 percent impervious surface limitation can be permitted if impervious areas are not increased and the applicant designs the project to comply with the intent of the rule to the maximum ex- tent practical. (3) All development projects, proposals, and designs shall comply with the following mandatory ' standards of tile 'North Carolina Sedimentation Pollution Control Act of 1973: (A) All development projects, proposals, and designs shall provide for a buffer zone along the margin of the estuarine water wluch is sufficient to confine visible siltation within 25 percent of ' the buffer zone nearest the land disturbing development. (B) No development project proposal or design shall permit an angle for graded slopes or fill which is greater than an angle which can be retained by vegetative cover or other adequate ero- sion -control devices or structures. ' (C) All development projects, proposals, and designs which involve uncovering more than one acre of land shall plant a ground cover sufficient to restrain erosion within 30 working days of ' ,VORTll C:I ROLINA : II).

(d) Development shall not have a significant adverse impact on estaurine resources. (5) Development shall not significantly interfere with existing public rights of access to, or use of, navigable waters or public resources. (6) No major public facility shall be permitted if such facility is likely to require extraordinary public expenditures for maintenance and continued use, unless it can be- shown that the public purpose sen•ed by the facility outweighs the required public expenditures for construction, maintenance, and continued use. For the purpose of this standard, "public facility" shall mean a project which is paid for in any part by public funds. (7) Development shall not cause major or irreversible damage to valuable, documented historic ar- chitectural or archaeological resources. (8) Established common-law and statutory public rights of access to the public trust lands and wa- ters in estuarine areas shall not be eliminated of restricted. Development shall not encroach upon public accessw•ays nor shall it limit the intended use of the accessways. (9) Within the AI;C for shorelines contiguous to waters classified as Outstandiung Resource Waters by the ENIC, no CANIA permit will be approved for any project which would,be inconsistent with applicable use standards adopted by the CRC, IiNIC or III C for estuarine waters, public trust waters, or coastal wetlands. For development activities not covered by specific use stand- ards, no permit will be issued if the activity would, based on site specific information, materially degrade the water quality or outstanding resource values unless such degradation is temporary. _.

Ocean hazard areas include beaches, frontal dunes, inlet lands, and other areas in wluch geologic, vegetative and soil conditions indicate a substantial possibility of excessive erosion or flood damage. 1listory Note: Statutory Authority G.S. 113A-107(a); 113A-107(b); 113A-113(b)(6a); 113A-113(b)(6b); 113A-113(b)(6d); 113A-124; Eff. September 9, 1977. .0302 SIGNIFICANCE OF THE OCEAN HAZARD CATEGORY (a) The primary causes of the hazards peculiar to the Atlantic shoreline are the constant forces exerted by waves, winds, and currents upon the unstable sands that form the shore. During storms, these forces are intensified and can cause significant changes in the bordering landforms and to structures located on them. liazard area property is in the ownership of a large number of private individuals as well as several public agencies and is used by a vast number of visitors to the coast. Ocean hazard areas are critical, therefore, because of both the severity of the hazards and the intensity of interest in the areas. (b) The location and form of the various hazard area landforms, in particular the beaches, dunes, and inlets, are in a permanent state of flux, responding to meteorologically induced changes in the wave climate. For this reason, the appropriate location of structures on and near these landforms must be ; reviewed carefully in order to avoid their loss or damage. As a whole, the same flexible nature of these landforms which presents hazards to development situated immediately on them offers protection to the land, water, and structures located landward of them. The value of each landform lies in the par- ticular role it plays in affording protection to life and property. Clhe role of each landform is described in detail in Technical Appendix 2 in terms of the physical processes most important to each.) Overall, however, the energy dissipation and sand storage capacities of the landforms are most essential for the maintenance of the landforms' protective function.

September 9, 1977. .0303 MANAGEMENT OBJECTIVE OF OCEAN IIAZARD AREAS ' (a) Tire CRC recognizes that absolute safety from the destructive forces indigenous to the Atlantic shoreline is an impossibility for development located adjacent to the coast. The loss of life and property to these forces, however, can be greatly reduced by the proper location and design of shoreline struc- tures and by care taken in prevention of damage to natural protective features particularly primary and ' frontal dunes. Therefore, it is the CRC's objective to provide management policies and standards for ocean hazard areas that serve to eliminate unreasonable danger to life and property and achieve a bal- ance between the financial, safety, and social factors that are involved in hazard area development. (b) The purpose of these Rules shall be to further the goals set out in G.S. 113A-102(b), with par- ticular attention to minimizing losses to life and property resulting from storms and long-term erosion, preventing encroachment of permanent structures on public beach areas, and reducing the public costs of inappropriately sited development. Furthermore, it is the objective of the Coastal Resources Com-mission to protect present cornmon-law and statutory public rights of access to the lands and waters of the coastal area.

The tables are available without cost from. any local permit ofcer or the Division'of Coastal Managcmcnt; -� ..��— I and (b) a distance landward from the recession line established in Subparagrapli..(a). of_tlus Paragraph to the recession line that would be generated by a storm having a.one percent chance of being_ equalled or exceeded in any-gi��enear. ' (2) The Itiglr hazard Flood Area. This is the area subject to high velocity waters (including, but not limited to, hurricane wave wash) in a storm having a one percent chance of being equalled or exceeded in any given year, as identified as zone V1-30 on the flood insurance rate maps of the Federal Insurance Administration, U.S. Department of IIousing and Urban Development. In the , absence of these rate maps, other available base flood elevation data prepared by a federal, state, or other source may be used, provided said data source is approved by the CRC. (3) Inlet Hazard Area. The inlet hazard areas are natural -hazard areas that are especially vulnerable ' to erosion, flooding and other adverse effects of sand, wind, and water because of their proximity, to dynamic ocean inlets. This area shall extend landward from the mean low water line a distance . sufficient to encompass that area within which the inlet will, based on statistical analysis, migrate, and shall consider such factors as inlet territory, , previous structurally weak areas near the inlet (such as an unusually narrow barrier island, an unusually long channel feeding the inlet, or an overwash area), and external, influences such as jetties and channelization. These areas shall be identified on inlet hazard area maps approved by the Coastal Resources Commission. In all cases, ' this area shall be an extension of the adjacent ocean erodible area and in no case shall the width of the inlet hazard area be less than the width of the adjacent ocean erodible area. (4) Unvegetated Beach Area. This is a dynamic area that is subject to rapid unpredictable landform. change from wind and wave action. The areas in this category shall be designated following de- ' tailed studies by the Coastal Resources Commission. These areas shall be designated on.maps approved by the Commission and available without cost from any local permit officer or the Di- vision of Coastal Management. , history Note: Statutory Authority G.S. 11.IA-107; 113it-113; 113A-124, Eff.

Ocean beaches are lands consisting of unconsolidated soil materials that extend ' from the mean low water line landward to a point where either: (1) the growth of vegetation occurs, or (2) a distinct change in slope or elevation alters the configuration of the landform, whichever is ' farther landward. (b) Primary Dunes. Prunary dunes are the first mounds of sand located landward of the ocean beaches having an elevation equal to the mean flood level (in a storm having a one percent chance of being equalled or exceeded in any given year) for the area plus six feet. The primary dune extends ' landward to the lowest elevation in the depression behind that same mound of sand (commonly referred to as the dune trough). (c) Frontal Dunes. In areas where there is a primary dune, that dune shall be deemed to be the frontal dune. Wliere there is no primary dune, the frontal dune is deemed to be tine first mound of sand , located landward of the ocean beach having sufficient vegetation, height, continuity and configuration VnDTrr !'.lunar ry 4 1ill fIVIC'Tn 1TTr'r r•nnr ni►►r►ni n __ l•11AW - COASTAL. t1lAjV.dGL•j11E'NT T15A: 0711.0300 to offer protective value. Man-made mounds seaward of the natural line of frontal dunes and dunes ' created after June I, 1979 shall not be considered to be frontal or primary dunes. (d) General Identification. For the purpose of public and administrative notice and convenience, each designated minor development pemut-letting agency with ocean hazard areas may designate, subject to CRC approval, a readily identifiable land area within which the ocean hazard areas occur. ' This designated notice area must include all of the land areas defined in .0304 of this Section. Natural or man-made landmarks should be considered in delineating this area. (e) "Vegetation Line" means the first line of stable natural vegetation, which shall be used as the reference point for measuring oceanfront setbacks. This line represents the boundary between the normal dry -sand beach, which is subject to constant flux due to waves, tides, storms and wind, and the more stable upland areas. It is generally located at or immediately oceanward of the seaward toe of the frontal dune and/or erosion escarpment. In areas where there is no stable natural vegetation present, this line shall be established by connecting or extending the lines from the nearest adjacent vegetation ' on either side of the site and by extrapolating (by either on -ground observation or by aerial photo- graphic interpretation) to establish the line. (0 "Erosion Escarpment" means normal vertical drop in the beach profile caused from high tide ' and/or storm tide erosion. (g) Measurement line means the line from which the ocean front setback as described in .0306(a) of this Subchapter is measured in the unvegetated beach area of environmental concern as described in .0304(a)(4) of this Subchapter. Procedures for determining the measurement line shall be adopted by ' the Commission for each area where such a line is designated. These procedures shall be available from any local permit officer or the Division of Coastal Management. ' history Note: Statutory Authority G.S. 113A-107; 113A-113(b)(6); 113A-124; Eff.

(1) If neither a primary nor frontal dune exists in the AEC on or behind the lot on which the de- velopment is proposed, the development shall be landward of the erosion setback line. The erosion setback line sliall be set at a distance of 30 tunes the long-term annual erosion rate from the first line of stable natural vegetation or measurement line, where applicable. In areas where the rate is less than 2 feet per year, the setback line shall be 60 feet from the vegetation line or measurement line, where applicable. (2) If a primary dune exists in the AEC on or behind the lot on which the development is proposed, the development shall be landward of the crest of the primary dune or the long-term erosion setback line, whichever is farthest from the first line of stable natural vegetation or measurement line, where applicable. For existing lots, however, where setting the development behind the crest of the primary dune would preclude any practical use of the lot, development may be lo- cated seaward of the primary dune. In such cases, the development shall be located behind the long-term erosion setback line and shall not be located on or in front of a frontal dune. The words "existing lots" in this Rule shall mean a lot or tract of land which, as of June 1, 1979, is specifically described in a recorded plat and which cannot be enlarged by combining the lot or tract of land with a contiguous lot(s) or tract(s) of land under the same ownership. (3) If no primary dune exists, but a frontal dune does exist in the AEC on or behind the lot on which the development is proposed, the development shall be set behind the frontal dune or behind the long-term erosion setback line, whichever :is farthest from the first line of stable natural vegetation or measurement line, where applicable. (4) Because large structures located immediately along the Atlantic Ocean present increased risk of loss of life and property, increased potential for eventual loss or damage to the public beach area and other important natural features along the oceanfront, increased potential for 1 iglier public costs for federal flood insurance, erosion control, storm protection, disaster relief and provision of public services such as water and sewer, and increased dilllculty and expense of relocation in the event of future shoreline loss, a greater oceanfront setback is required for these..structures ♦• /1 T 4• r r / 1 .1. . . n.

(5) Established common-law and statutory public rights of access to public trust lands and waters ' in ocean hazard areas shall not be eliminated or restricted. Development shall not encroach upon public accessways nor shall it limit the intended use of the accessways. (b) In order to avoid weakening the protective nature of ocean beaches and primary and frontal ' dunes, no development will be permitted that involves the significant removal or.relocation of primary or frontal dune sand or vegetation thereon. Other dunes within the ocean hazard area shall not be disturbed unless the development of the property is otherwise impracticable, and any disturbance of any other dunes shall be allowed only to the extent allowed by Rule .0308(b). ' (c) In order to avoid excessive public expenditures for maintaining public safety, construction or placement of growth -inducing public facilities to be supported by public funds will be permitted in the ocean hazard area only when such facilities: (1) clearly exhibit overriding factors of national or state interest and public benefit, , (2) will not increase existing hazards or damage natural buffers, (3) will be reasonably safe from flood and erosion related damage, (4) will not promote growth and development in ocean hazard areas. ' Such facilities include, but are not limited to, sewers, waterlines, roads, bridges, and erosion control. structures. (d) Development shall not cause major or irreversible damage to valuable documented historic ar- chitectural or archaeological resources documented by the Division of Archives and History, the Na- ' tional I listorical Registry, the local land -use plan, or other reliable sources.

These measures shall be implemented at the applicant's expense and may include actions that will: ' (1) minimize or avoid adverse impacts by limiting the magnitude or degree of the action, (2) restore the affected environment, or (3) compensate for the adverse impacts by replacing or providing substitute resources. 6) Prior to the issuance of any permit for development in the ocean hazard AECs, there shall be a ' written acknowledgement from the applicant that the applicant is aware of the risks associated with development in this hazardous area and the limited suitability of this area for permanent structures. By the Coastal granting permits, Resources Commission does not guarantee the safety of the develop- ' ment and assumes no liability for future damage to the development. (k)' All relocation of structures requires permit approval. Structures relocated with public funds shall comply with the applicable setback line as well as other. applicable AEC rules. Structures including septic tanks and other essential accessories relocated entirely with non-public funds shall be relocated ' the maximum feasible distance landward of "the present location; septic tanks may not be located seaward of the primary structure. In these cases, all other applicable local and state rules shall be met. (1) Permits shall include the condition that any structure shall be relocated or dismantled when it becomes imminently threatened by changes in shoreline configuration. The structure(s) shall be relo- ' cated or dismantled within two years of the time when it becomes imminently threatened, and in any case upon its collapse or subsidence. However, if natural shoreline recovery or beach renourish ment takes place within two years of the time the structure becomes imminently threatened, so that the ' structure is no longer imminently threatened, then it need not be relocated or dismantled atthat time. ,\'OR 17!

In all cases, this development shall only be permitted if it is landward of the vegetation line; involves no significant alteration or removal of primary or frontal dunes or the dune vegetation; has over -walks to protect any existing dunes; is not essential to the continued existence or use of an associated principal development; is not required to satisfy minimum requirements of local zoning, subdivision or health regulations; and. meets all other non -setback requirements. of this Subchapter...._._,____ (b) Where strict application of the oceanfront setback requirements of Rule .0306(a) of this Sub- chapter would preclude placement of permanent substantial structures on lots existing as. of June 1, 1979, single family residential structures may be permitted seaward of the applicable setback line in ocean erodible areas, but not inlet hazard areas, if each of the following conditions are met: (1) The development is set back from the ocean the maximum feasible distance possible on the ex- isting lot and the development is designed to minimize encroachment into the setback area; (2) Tile development is at least 60 feet landward of the vegetation line; (3) The development is not located on or in front of a frontal dune, but is entirely behind the landward toe of the frontal dune; (4) The .development incorporates each of the following design standards, which are in addition to those required by Rule .0303(d) of tlds Subchapter. (A) All pilings have a tip penetration that extends to at least four feet below mean sea level; (B) The footprint of the structure be no more than 1,000 square feet or 10 percent of the lot size, whichever is greater. (5) All other provisions of this. Subchapter and other state and local regulations are met. If the development is to be serviced by an on -site waste disposal system, a copy of a valid permit for such a system must be submitted as part of the CA'10A permit application. For the purposes of this Rule, an existing lot is a lot or tract of land which, as of June 1, 1979, is spe- cifically described in a recorded plat and which cannot be enlarged by combining the lot or tract of land ,__., with.a.contiguous lot(s) or tract(s) of land under the same. ownership,..- Z_ _footprint is defined as the I,VOR 7*11 C.-I ROLL, I ; I D,11LVI.SMA HIT CODE 02111192 Page 3 Appendix 3: Zoning Ordinance — Non -Conformities, Town of Kill Devil Hills Appendix 3 ' § 21-5.4 HILL DEVIL HILLS TOWN CODE development in the trict, a change in the scale or features of the proposed prior petition.

(A) Intent. This chapter establishes standards and guidelines on the use and development of land by establishing minimum standards as guidelines for managing growth in a direction that will result in an environment satisfactory to the residents and visitors of Kill Devil Hills. In many instances, land and improvements were developed or proposals for such were initiated prior to the adoption of this chapter. These situations may not meet the minimum standards contained in this chapter because they were developed under no specific standards or under standards which were less restrictive. The board recognizes that the strict application of these standards to such situations may create certain hardships for the property owner. Therefore, it is the intent of this article to permit, under certain circumstances, these nonconformities to continue but not to encourage their survival. It is further the intent of this article that nonconformities shall not be enlarged upon, expanded or extended, nor be used as grounds for adding other structures or uses prohibited elsewhere in the same district. It is further the intent that, in cases of extreme hardship, application for a variance may be made to the board of adjustment. (B) Nonconforming lots of record.. (1) In any district in which single-family dwellings are permitted, a single-family dwelling and customary accessory buildings may be erected on any single lot of record in the Dare County Registry of Deeds as of the effective date of this chapter notwithstanding Supp. No. 5 1300 1 ZONING § 21-6.1 limitations imposed by other provisions of this chapter. These provisions shall apply even though such lot fails to meet the requirements for area or width that are gen- erally applicable in the district; provided, that yard dimensions and requirements other than those applying to area and width of the lot shall conform to the regulations for the district in which such lot is located. ' (2) Any expansion of any building occupying a nonconforming lot, as of the effective date of this chapter, must comply with the minimum requirements of the ordinance for front, side and rear yard setbacks, height, density and coverage for the district in ' which the lot is located. (C) Nonconforming uses of land. ' (1) Where, at the effective date of this chapter, existing uses of land are no longer permissible under the terms of this chapter, such use may be continued provided that: , (a) No such nonconforming use shall be enlarged or increased, -nor extended to oc- cupy a greater area than was occupied at the effective date of this chapter; (b) No such nonconforming use shall be moved in whole or in part to any other ' portion of the lot or parcel occupied by such use at the effective date of this chapter; (c) If such nonconforming use of land ceases for any reason for a period of more than l ' sixty (60) days, any subsequent use of such land shall conform to the require- ments specified by this chapter for the district in which such land is located unless good faith attempts are made to rent or lease the land for the same nonconforming use. In no event will the period exceed one hundred and eighty (180) days. Land occupied by seasonal uses shall be exempt from this provision. (d) No additional structures not conforming to the requirements of this chapter shall , be erected in connection with such nonconforming use of land; (e) A conforming or nonconforming use of land may not be changed to any other ' nonconforming use. (D) Nonconforming structures. Where, ' (1) on the effective date of this chapter, then existing structures could not be built under the terms of this chapter by reasons of restrictions or area, lot coverage, height, yards, its location on the lot or other requirements concerning the structure, such ' structure may be continued so long as it remains lawful, subject to the following provisions: (a) No such nonconforming structure may be enlarged or altered in a way which increases its nonconformity, but any structure or portion thereof may be altered to decrease its nonconformity. (b) In the event a natural disaster, casualty loss or accidental occurrence leads to , extensive damage to a structure that is nonconforming in any respect or a struc- ture that is used in a nonconforming manner, that structure or use may be ' repaired or reconstructed to one hundred (100) percent of its status as of the date Supp. No. 6 1301 1 ' § 21-6.1 HILL DEVIL HILLS TOWN CODE of enactment of this chapter. This provision becomes invalid thirty (30) years from that date unless the structure suffers extensive damage during that thirty- year period. In that event the provision becomes invalid thirty (30) years from the date of loss. The following restrictions apply during the period: 1. The total amount of space devoted to a nonconforming use may not be re-. ' stricted. 2. The reconstructed building may not be more nonconforming with respect to ' dimensional restrictions such as yard requirements, height limitations, lot coverage, or density requirements, and such dimensional nonconformities must be minimized to the extent feasible or practical without undue hard- ship. 3. If more than fifty (50) percent of the structure's value is destroyed, recon- struction work may be done only after issuance of a conditional use permit by the board of commissioners. The board of commissioners shall issue the permit if it finds that the work will be done in accordance with this section and that ' all reasonable effort has been made to reduce nonconforming items to the extent possible without undue hardship and that the reconstructed building will not make the property more noncomplying than it was before the damage, occurred. The valuation for computation of percentage,of value destroyed ' shall be that valuation appearing on the January 1 tax assessment of the property for Dare County, the year immediately preceding the loss. In the event of a dispute in valuation or percentage of destruction, an appraisal ' certified and submitted by a qualified appraiser shall be presumptive evi- dence that the appraised value of the structure and the amount of destruction ' is as certified by an appraiser. (c) Any such nonconforming structure located on a lot adjacent to the Atlantic Ocean ' or Sound waters may be moved on the same lot provided that such movement does not increase the nonconformity. All reasonable efforts will be made to reduce nonconforming items to the extent feasible or practical without undue hardship. (d) Renovation to nonconforming structures where cost of the work exceeds ten (10) ' percent of the appraised value of the structure and not required due to partial or total destruction of the structure may be done pursuant to a conditional use ' permit issued by the board of commissioners. 1. When a "state of emergency" is declared by the mayor, the planning depart- ment may issue permits for a single-family dwelling and permitted duplexes if it finds that the work will be done in accordance with this section and that all reasonable effort has been made to reduce nonconforming items to the extent possible without undue hardship and that the reconstructed building ' will not make the property more noncomplying than it was before the damage occurred. 2. When a "state of emergency" is declared by the mayor, all commercial sites ' and multifamily dwellings in excess of a duplex that cannot meet local, state Supp. No. 6 1302 J 1 ZONING § 21-6.1 and federal ordinances will be reviewed by the planning board. The planning board will recommend approval if it finds that the work will be done in accordance with this section and that all reasonable effort has been made to , reduce nonconforming items to the extent possible without undue hardship and that the reconstructed building will not make the property more non- , complying than it was before the damage occurred. If the planning board recommends approval, the mayor may authorize the building inspector to issue a permit. If the planning board does not recommend approval, the board ' of commissioners shall make the determination of authorizing a permit. - 3. Section 21-6.1(D)(1)(d)4. and 5. shall expire one (1) year from the date of adoption of this section. , (E) Nonconforming uses of a structure. (1) If a lawful use of a structure, or of structure and land in combination, exist at the ' effective date of adoption of this chapter, that would not be allowed in the district under the terms of this chapter, the use may continue subject to the following provi- sions: ' (a) No existing structure devoted to a use, not permitted by this chapter for the district in which it is located shall be enlarged, extended, constructed, recon- structed, moved or structurally altered, except in changing the use of the struc- ture to a use permitted in the district in which it is located. (b) A nonconforming use may not be extended within or without the structure in ' which it was located at the time of adoption of this chapter. (c) Any structure, or structure and land in combination, in or on which a noncon- forming use is superseded by a permitted use, shall thereafter conform to the ' regulations for the district in which. the structure is located and the noncon- forming use may not be resumed. (d) When a nonconforming use of a structure, or structure and land in combination, ' is discontinued or ceases to exist for six (6) consecutive months, the structure or structure and land in combination, shall not thereafter be used in conformance with the regulation of the district in which it is located. Such nonconforming use ' shall not be deemed to have ceased in the case of good faith attempts to rent or lease the vacant structure, building or land for the same nonconforming use as the one which was discontinued. ' (e) A conforming or nonconforming use of a structure, or structure and land in combination,*at the time of adoption of this chapter, may not be exchanged for ' any other use or activity not authorized for the district in which the structure is located. M Where nonconforming use status applies to a structure and land in combination, , removal or destruction of the structure shall eliminate the nonconforming status of the land. (g) Maintenance and repairs which are necessary to keep a structure which houses ' a nonconforming use in safe and sound condition are permitted. Supp.1No. r 1303 11 7 H § 21-6.1 HILL DEVIL HILLS TOWN CODE (F) Nonconforming signs. (1) A sign which existed legally prior to the adoption of this chapter but which could not be erected or displayed under the terms of this chapter may be allowed to continue subject to the following provisions: (a) Minor repairs and maintenance of nonconforming signs including, but not lim. ited to, repainting, electrical repairs, neon tubing repairs, will be allowed. No structural repairs or changes in size, shape or message of a sign will be permitted except to make the sign comply with the requirements of this chapter. (b) New signs related to legally established nonconforming uses may be erected provided they comply with the sign regulations which apply to the use in the most restricted district in which the use is permitted. (c) Nonconforming signs will be removed if the activity, business or use to which it relates has been discontinued for a period of more than one hundred eighty (180) consecutive days. (d) When it becomes necessary to reconstruct any sign for a particular business, every associated sign related to this business, including directional, must also be brought into compliance with this chapter. (G) Change of tenancy or ownership. A change of tenancy, ownership or management of any existing nonconformities is allowed provided there is no change in the nature or character of such nonconformities. (H) Maintenance. Minor repairs to or routine maintenance of nonconformities are per- mitted and encouraged. (I) Permitted conditional uses not nonconforming. Any use which is permitted as a con- ditional use in a district under the terms of this chapter shall not be deemed a nonconforming use in such district but shall, without further action, be considered a conforming use.

It is important that local officials clearly understand the joint federal -state -local procedures for providing assistance to rebuild after a storm so that local damage assessment and reconstruction efforts are carried out in an efficient manner that qualifies the community for the different types of assistance that are available. The requirements are generally delineated in the Disaster Relief Act of 1974 (P.L. 93-288) which authorizes a wide range of financial and direct assistance to communities and individuals. After a major storm event, local damage assessment teams will survey - impacted areas to identify any citizens who need immediate medical attention, food or shelter. They will also survey storm damage within the community. Damage information will be compiled and summarized and the nature and extent of damage will be reported to the North Carolina Division of Emergency Management (DEM). DEM will compile local data and make recommendations to the Governor concerning state actions. At this point, the Governor may request a Presidential declaration of "emergency" or "major disaster." A Presidential declaration makes a variety of federal resources available to local communities and individuals. Executive Order 1198 (Floodplain Management) directs all federal ' agencies to avoid either directly or indirectly supporting future unwise development in floodplains, and Section 406 of the Disaster Relief Act can require communities, as a prerequisite for federal disaster assistance, to ' take specific actions to mitigate future flood losses. Kill.Devil Hills has been provided a comprehensive listing of the Federal Disaster Assistance Programs that may be available following a major storm. ' A local assessment team is in place and include individuals who are qualified to give reliable estimates of the original value of structures, an estimated value of sustained damages and a description of the repairs. The ' logistics involved in assessing damage in the Town after a major storm will possibly necessitate the organization of several damage assessment teams. ' The several damage assessment teams should include a public property survey team, a business and industry survey team and a private dwelling survey team. The public property survey team should consist of town department head(s), a professional engineer (volunteer), an architect (volunteer), and a ' police officer (driver). The business and industry survey team should consist of a tax assessor, ' a building inspector (CAMA Permit Officer), an industrial/commercial real estate broker (volunteer), a chamber of commerce representative (volunteer), an architect (volunteer), and a police officer (driver). 92-32 7 - 1 The private dwelling survey team should consist of a tax assessor, a building inspector, a residential real estate broker (volunteer), a building contractor (volunteer), and a police officer (volunteer). Recruited volunteers should receive training so that the members of the damage assessment team are familiar with required damage classification procedures and reporting requirements. It is suggested that Dare County assume the responsibility for developing and implementing a training program for both county and town damage assessment teams. In establishing the assessment teams, it might be difficult to fill certain positions, because the services of some individuals will likely be in a great demand after a storm disaster. The Emergency Management Coordinator should establish and maintain an active "volunteer file" with standing instructions on where to report following a storm. Damage assessment forms and procedures should be prepared and distributed to volunteers as part of the training program. Damage assessment is defined as a rapid means of determining a realistic estimate of the amount of damage caused by a natural or man-made disaster. For a storm disaster, it is expressed in terms of number of structures damaged; magnitude of damage by type of structure, estimated total dollar loss and estimated total dollar loss covered by insurance. After a major storm event, members of the Damage Assessment Team should report for a briefing from the Emergency Management Coordinator. The Emergency Management Coordinator should establish field reconnaissance priorities according to the extent of damage and where landfall occurred. Because of the potentially large job at hand, the limited personnel resources available to conduct the assessments and the limited time within which the initial assessment must be made, the first phase of the assessment shall consist of only an external visual survey of damaged structures. A more detailed second phase assessment can be made after the initial damage reports are filed. The initial damage assessment should make an estimate of the extent of damage incurred by each structure and identify the cause such as wind, flooding or wave action. This first phase assessment should be made by a "windshield" survey. Damaged structures should be classified -.in accordance with guidelines established by the State DEM. The four damage classifications are destroyed, major, minor, and isolated. They are described later in this section. It will be necessary to thoroughly document each assessment. In many cases, mail boxes and other information typically used to identify specific structures will not be found. Consequently, the damage assessment team must be provided with functional maps and photographic equipment in order to record and document its field observations. Enough information to complete the damage assessment worksheet must be obtained on each damaged structure. The second phase of the damage assessment operation should estimate the value of the damages sustained. This operation should be carried out under the direction and supervision of the Emergency Management Coordinator. A special team consisting of tax clerks, tax assessment personnel and other qualified staff should be organized by the Emergency Management Coordinator. 92-32 7 - 2 P ' This team should be incorporated into the plan. In order to estimate total damage values, the Emergency Management Office should have a set of property tax maps (including aerial photographs) identical to those utilized by the ' damage assessment field team, town maps delineating areas assigned to each team and copies of all Town property tax records. In order to produce the damage value information required, the following ' methodology should be employed: 1. The number`df businesses and residential structures that have been ' damaged within the Town should be summarized by damage classification category. 2. The replacement cost or fair market value of each damaged ' structure excluding land value should be obtained from the owner or occupant or estimated from existing tax records or best available data and professional judgement. The damage ' classification categories are: a. MIN (damages/uninhabitable) - The term "MIN" is an ' abbreviation for "minor" damage. "Minor" damages, when considering housing damages, are defined as physical damages which make the impacted home uninhabitable and have damages of 10% or less of the home's replacement cost or fair market ' value. "Min" damages are those which will require minimal repairs to doors, windows, floors, utilities, etc., to make the structure habitable again. ' b. MAJ (damages/uninhabitable) - The term "MAY" is an abbreviation for "major" damage. "Major" damages are ' defined as physical damages which make the impacted structure or facility uninhabitable and have damages between 11% and 74% of the home's replacement cost or fair market value. A home with extensive damages to its foundation, ' roof, and walls would be classified "MAY" damages. C. DEST (damages/uninhabitable) - The term "DEST" is an ' abbreviation for "destroyed". "Destroyed" is defined to mean those homes which have been made uninhabitable as a result of the incident and have damages in excess of 75% of ' 92-32 their replacement cost or fair market value. If reconstruction or relocation are the only options to restoring the home to its original use, it should be classified "DEST". d. ISO. "ISO" is an abbreviation for "isolated." Even though the home may not have sustained any physical damages, the structure is considered unusable if the home is no longer accessible or if there is a lack of essential utilities such as electricity, water, etc. 3. The total value of damage for the incorporated areas of the Town should then be summarized. 7-3 4. The estimated value loss covered by hazard- insurance should then ' be determined. 5. Damage assessment reports should be used to: ' a. obtain information on the various types of assistance that might be available from federal and state agencies; b. understand the various assistance programs; and ' C. apply for such assistance. When a major storm does eventually hit the Town and major damages occur, consideration should be given to establishing an assistance ' team to carry out the above functions as long as there is a need to do so. ' The Town should appoint a Recovery Task Force to oversee the reconstruction process. The Recovery Task Force should consist of the: • chairman of the Board of Commissioners; ' 0 town manager; • emergency management coordinator; • town tax appraiser; ' • town finance director, e town code inspector; and • town planning and development director. ' Under certain circumstances, interim development moratoriums should be used in order to give a local government time to assess damages, to make sound decisions and to learn from its storm experiences. Such moratoriums must be , temporary and must be reasonably related to the public health, safety and welfare: It is not possible -to determine prior to a storm whether a temporary development moratorium will be needed. Such a measure should only be used if ' damage in a particular area is very serious and if redevelopment of the area in the same manner as previously existed would'submit the residents of the', area to similar public health and safety problems. , The need for a temporary development moratorium should be assessed by the Town's Emergency Management Office within one week after the damage assessment process is completed. Such assessment should clearly document why , such a moratorium is needed, delineate the specific uses that would be affected by the moratorium, propose a specific schedule of activities and actions that will be taken during the moratorium period and establish a specific time period during which the moratorium will be in effect. In addition, Section 1362 of the Flood Insurance Act authorizes the ' Federal government to purchase property deemed unsuitable for reconstruction. Upon the determination by the Board of Commissioners that any section of Kill Devil Hills is not suitable for reconstruction, federal acquisition should be ' recommended. A schedule for staging and permitting repairs should be adhered to. The schedule should be considered and revised as necessary after the damage ' assessment activities are completed. Generally, the schedule for staging and permitting repairs should be as follows: 92-32 7 - 4 ' 1. Building permits to restore structures located outside of designated AEC areas that were previously built in conformance with local codes, standards and the provisions of the North Carolina Building Code should be issued automatically. 2. All structures suffering major damages as defined should be repaired -or rebuilt to conform with the provisions of the North ' Carolina Building Code and other related ordinances. 3. All structures suffering minor damage as defined herein should be permitted to be rebuilt to their original state before the storm condition provided non -conforming use regulations are met. ' 4. For all structures in designated AEC's and for all mobile home locations, a determination should be made for each AEC as to whether the provisions of the building code, regulations for AEC's or other ordinances appeared adequate in minimizing storm damages. ' For areas where the construction and use requirements appear adequate, permits should be issued in accordance with either 1, 2 or 3 above. For AEC's where the construction and use requirements do not appear to have been adequate in mitigating damages, a ' temporary development moratorium for all structures located within that specific AEC should be considered. ' 5. Permits should not be issued in areas subject to a temporary development moratorium until such a moratorium is lifted by the Town or Dare County. 6. All damaged water and sewer systems (both public and private) shall be repaired so as to be flood -proofed by methods and construction standards certified by a registered professional ' engineer where practicable. ' 7. All damaged roads used as major evacuation routes in flood hazard areas should be repaired so as to be elevated at least one foot above the 100-year floodplain elevation where practicable.. ' 8. All local roads that have to be completely rebuilt should be elevated so as to be above the 100-year flood plain elevation, using current specifications for reconstruction. 1 ' 92-32 7-5 (3) (4) 92-32 • Kill Devil Hills Administrative Services Building; • Kill Devil Hills Water Administration Building; • Thomas A.

Public Participation Policy Selected in 1987: The Town encourages public participation in all land use decisions, procedures, commissions, advisory agencies, and will establish a non- resident property owner advisory commission. Implementation Analysis as of 1992: To successfully implement this policy, the Town advertised public meetings and utilized direct correspondence, radio public service announcements and public notices to.notify the public of meetings and opportunities to provide input, thereby generating public interest and promoting public education. A "Sunshine List" was maintained to notify interested persons of meetings and public hearings. A non-resident property owner advisory commission has not been established. Hurricane Mitigation Planning (a) Storm Hazards Planning and Mitigation Policy Selected in 1987: Hill Devil Hills Flood Damage Prevention Ordinance - This ordinance should be designed to meet the National Flood Insurance Program. The ordinance should also be designed to minimize flood damage by referring to accepted practices and methods that would set forth uniform rules for developers. Implementation Analysis as of 1992:_ The Town designed its Flood Damage Prevention Ordinance to be consistent with the National Flood Insurance Program. The ordinance has been adopted and implemented. It refers to accepted practices and methods that set forth uniform rules for developers. Policy Selected in 1987: Kill Devil Hills Hazard Area Redevelopment Policy - This policy is related to the Building Code and the Flood Damage Prevention Ordinance. The policy should indicate that reconstruction after a storm be subject to the regulations of the building code which 2 - 19 E r r ' states that if any building damaged in excess of fifty percent of its value to conform with code requirements for new buildings when repaired. Also the flood damage prevention ordinance should ' require that all existing structures must comply with requirements related to the 100-year flood elevation, which is if any repair, reconstruction, or improvement of a structure is equal to or ' exceeds fifty percent of the market value, the improvement or repair must follow the building code regulations. ' Implementation Analysis as of 1992: The Town did not adopt a Hazard Area Redevelopment Policy but did modify its zoning ordinance to address some redevelopment issues. ' Policy Selected in 1987: The Town will continue to implement area wide street address ordinance to increase the damage assessment team's ability to identify remaining structures. ' Implementation Analysis as of 1992: The Town successfully implemented this policy. Policy Selected in 1987: ' The Town favors the establishment of a post -disaster fund of State monies to be allocated to N.C. communities that have been declared major disasters. This state fund would be used to supplement Federal disaster relief aid. ' Implementation Analysis as of 1992: ' The Town took no further steps beyond selecting and stating this policy supporting the establishment of a State funded post - disaster relief fund. ' (b) Post -Disaster Reconstruction Planning Policy Selected in 1987: ' Recommended Reconstruction Policies - It is recommended that the Town Task Force consist of the following individuals: ' • Chairman of the Town Board; • Town Manager; ' • Emergency Management Coordinator; • Town Tax Appraiser; 0 Town Finance Director, • Town Code Inspector; and, • Town Planning and Development Director. 92-32 2 - 20 92-32 Implementation Analysis as of 1992: ' A Task Force has been set up by the Town although a Hazard Area Redevelopment Policy has not been adopted. ' Policy Selected in 1987: Building permits to restore structures located outside of , designated AEC areas that were previously built in conformance with local codes, standards and the provision of the North Carolina Building Code shall be issued automatically. ' Implementation Analysis as of 1992: No policy providing for this procedure was adopted. ' Policy Selected in 1987: , All structures suffering major damages as defined in the Kill Devil Hills Damage Assessment Plan shall be repaired or rebuilt to conform with the provision of the North Carolina Building Code and ' other related ordinances. Implementation Analysis as of 1992: , A Damage Assessment Plan was not adopted. Policy Selected in 1987: ' All structures suffering minor damage as defined in the Kill Devil . Hills Damage Assessment Plan shall be permitted to be rebuilt'to ' their original state before the storm condition provided non- conforming use regulations are met. Implementation Analysis as of 1992: ' A Damage Assessment Plan was not adopted. However, language was added to the Town's zoning ordinance concerning redevelopment. , Policy Selected in 1987: ' For all structures in the designated AEC's and for all mobile home locations, a determination shall be made for each AEC as to whether the provisions of the N.C. Building Code, the State Regulations for Areas of Environmental Concern, or other , ordinances appeared adequate in minimizing storm damages. For area where the construction and use requirements appear adequate, permits shall be issued in accordance with permitting policies 1, ' 2, and 3. For AEC's where the construction and use requirements do not appear to have been adequate in mitigating damages, a Temporary Development Moratorium for all structures located within ' that specific AEC shall be considered. 2 - 21 1 IImplementation Analysis as of 1992: No temporary development moratoria were imposed by the Town. Policy Selected in 1987: All individual mobile homes located in mobile home parks ' sustaining some damage to at least 50% of their mobile homes in the park shall be required to conform to current ordinances. Implementation Analysis as of 1992: This policy has not been implemented nor is it necessary since ' there are no mobile home parks in Kill Devil Hills. Policy Selected in 1987: ' Permits shall not be issued in areas subject to a Temporary• Development Moratoria until such a moratoria is lifted by the Town ' or Dare County. Implementation Analysis as of 1992: ' No temporary development moratoria were imposed by the Town or Dare County. ' Policy Selected in 1987: All damaged water and sewer systems (both public and private) shall be repaired so as to be elevated above the 100-year flood ' plain or shall be flood -proofed, with methods employed and the. construction certified by a registered professional engineer.

' Policy Selected in 1987: All damaged roads used as major evacuation routes in flood hazard areas shall be repaired so as to be elevated at least one foot above the 100-year flood plain evacuation. ' Implementation Analysis as of 1992: This policy deals primarily with NC 12 nd U.S.158 By -Pass which both already meet or exceed the construction standard set forth. ' 92-32 2 - 22 1 Natural Hazards Planning 1. 2. 92-32 Introduction The Division of Coastal Management encourages local governments to focus on three phases of natural hazards planning. These include storm hazard mitigation, post disaster recovery, and evacuation plans. The 1987 Town of Kill Devil Hills Land Use Plan included "Storm Hazards Planning and Mitigation," "Post Disaster Reconstruction Plan," and "Hurricane Evacuation" sections as a part of Chapter VII. Much of the information contained in APPENDIX 5 "Elements of Emergency Management Planning", APPENDIX 6 "Hazard Areas", and APPENDIX 7 "Post Disaster Recovery" of this Update was taken from the 1987 Plan. Reviews of this information and the defacto procedures that Town staff and others follow in time of emergency pointed to the need for a separate Natural Hazards Plan to incorporate the required issue areas and to accurately portray and set forth the duties and responsibilities of the Town, Dare County, and those agencies and personnel called upon in time of emergency. Storm Hazard Mitigation BACKGROUND Storm hazards are far more serious than commonly perceived. The series of tornadoes which struck eastern North Carolina in March of 1984 and publicity surrounding the devastation caused by Hurricane Hugo in 1989 and Hurricane Andrew in 1992, have increased awareness of the need for storm hazard mitigation and natural hazards planning. There are numerous natural hazards and many are likely to occur in Kill Devil Hills. These include: • flooding and erosion; • high winds (hurricanes and northeasters); • tornadoes; and, 0 snow and ice storms. Of particular importance to Outer Banks localities' land use planning are storms and their resultant erosion, flooding, and high winds. In order to effectively plan for such hazards, a comprehensive approach is necessary. APPENDIX 5 discusses the elements of emergency management planning. It also describes the ties between emergency management planning and land use planning necessary to achieve a comprehensive approach for mitigating hazards. - 67 - 1 1 1 Because of the proximity of the Atlantic Ocean and the ' Roanoke Sound and the nature of the barrier island upon which Kill Devil Hills is located, the occurrence of a major ' hurricane could create a hazard zone that would encompass the entire community. Depending upon the severity and nature of the storm striking Kill Devil Hills, certain lower lying areas would be subject to flooding initially with the ' higher areas containing development remaining relatively safe except during the most severe of storms. In APPENDIX 6, hazard areas in Town are defined and are discussed ' relative to storm severity. Development has been intense within the hazard zones of Kill Devil Hills although most of it has occurred in the higher, ' less floodprone areas of the Town. As the Town's population and reliance on tourism increases, there will be a greater demand for intensifying water oriented land uses. Kill .Devil Hills is in the mainstream of intense coastal ' development pressures and it should be anticipated that further development in and near hazard areas will occur. ' At the present time there are some mitigation policies in effect. Kill Devil Hills has a zoning ordinance, building codes, and a flood damage prevention ordinance. Other ' regulations include National Flood Insurance Program regulations and state and federal emergency management regulations. Currently, Kill Devil Hills permits development to occur in hazard areas. Similarly, it is expected that development ' within the hazard areas will occur in the future. If development is to occur in these areas it should be hazard - resistant. Where,and what kind of development should occur in Kill Devil Hills, and how this development should be constructed so as to.minimize damage in the event of a major ' storm are questions facing those that formulate policies and regulations in the Town. ' POLICY The Town supports the development and adoption of a Natural ' Hazards Plan. It also supports the continued enforcement of the Kill Devil Hills Flood Damage Prevention Ordinance, the continued implementation of the area -wide street address ordinance, and the establishment of a post -disaster fund of ' state monies to supplement federal disaster relief aid to be allocated to North Carolina communities that have been ' declared major disasters. 92-32 - 68 - IMPLEMENTATION STRATEGY 3. 92-32 The Town will continue to enforce existing ordinances and take measures as necessary to enhance storm hazard mitigation efforts including support of the Dare County Emergency Management Plan. It will identify supplemental emergency powers that state statutes allow and seek the necessary authorization from the state to exercise same. The Town will develop and adopt a Natural Hazards Plan in 1993. Post -Disaster Recovery BACKGROUND Clearly defined post -disaster recovery procedures will permit Kill Devil Hills to deal with the aftermath of a storm in an organized and efficient manner. APPENDIX 7 provides a conceptual approach to post disaster recovery -- to be used by the Town as a general guide while a Natural Hazards Plan is developed and adopted. Post -disaster recovery encompasses three distinct reconstruction periods. The emergency period is the reconstruction phase immediately after a storm. The emphasis is on restoring public health and safety, assessing the nature and extent of storm damage and qualifying for and obtaining federal and state assistance. The restoration period is the weeks and months following a storm disaster. The emphasis during this period is on restoring community facilities and utilities and essential business so the municipality can return to normal activities. The. replacement period is the period during which the community is rebuilt. This period could last from months to years depending on the nature and extent of the damages incurred. POLICY The Town supports in place and the Hazards Plan. It Management Plan. j the continued use of procedures currently , development and adoption of a Natural also supports the Dare County Emergency IMPLEMENTATION STRATEGY The Town will develop and adopt a Natural Hazards Plan in 1993. 1 Appendix 6: Dare County Recovery and Re -Entry Stages L E Appendix 6 n H RECOVERY AND REENTY STAGES* RS-5 Catastrophic damage has rendered transportation routes impassable; destroyed or damaged severely damaged essential :11 •utility production or distribution systems; and created dangerous debris or unsanitary 1•: of emergencyand/Ormartlal • :111 11 11 effect for an indefinite period of time.

' Our goal is to identify and provide safety for critical equipment and supplies in the event of a threatening storm to Kill Devil Hills and to be available to assist in the reconstruction phase. F II H An organizational meeting will be held of all department employees. Personnel will be rotated so that employees can safely secure their families and homes. Each employee will notify the Finance Director of where they can be reached in the event they evacuate and they will be told it is their responsibility to monitor news media regarding reentry procedures after a storm. Depending on the storm category the following actions will be taken: CATEGORY I AND II STORMS: A. All equipment and supplies will be safely stored away, from window locations. A back up of the town's computer system will be made by the MIS technician including Finance, Planning, Fire, Administration, Water Administration and Public Works departments. All computer work stations will be disconnected to prevent electrical damage. CATEGORY III AND HIGHER STORMS: The following procedures will be followed for all Category IV and V storms. They will be followed for all Category III storms depending on advice received from the Town Manager and County Control Group and after all factors have been evaluated. A. The battery pack for the laptop computer will be charged and this piece of equipment will remain with the Finance Director along with a printer and cable. The Finance Director will also keep the operating account checkbook. B. Tax maps and tax scrolls showing valuations will be sent out of town for safety with an employee who evacuates. This information will be needed to determine property losses during reconstruction. (As the finance department is working to replace its financial software we are looking to include software for taxes which will make this tax information more readily available to us which would be especially helpful during reconstruction after a storm.) C. Battery, flashlight, and film supplies will be replenished. D. Three (3) complete back ups of the computer system will be done by the MIS technician for the Finance, Planning, Fire, Administration, Water Administration and Public Works departments. Two of these backups will leave the County with employees who are evacuating and the third backup will be stored in the records storage building.

After careful review of the plan, it has become obvious that the Planning Department ' has a need for a 2-way radio system for communications in the event of a disaster. I recommend that the Planning Department be issued, loaned or purchase 4-6 VHF radios for such occasions. Ideally, these radios should be hand held battery operated and effective within a minimum of a 5 mile radius. The radios should be adaptable to an externally mounted VHF mobile antenna (and include this antenna) and include power adapters to operate units from a 12 vehicle electrical system. These radios would be beneficial utilized in the normal day to day departmental operations.

To successfully understand the magnitude of threats from hurricanes and other ' severe storms, it is important to understand the nature of our property "at risk." Several exercises were completed to help understand the dollar value of the relative vulnerability of structures. The following methodology was utilized: ' - Total tax value of structures in all "flood zones" as of 3/94 ' - Exposure to a strong Category #3 storm - 130 mph sustained winds, 9-12 foot storm surge ' - Average tide (no lunar tide event) - Does not include value of roads, waterlines, powerlines, telephone lines, etc. SUMMARY A ' Kill Devil ' i Hills Total Structure Value (3/94) $377,577,600.00 ' Structure value in Flood Zone "X"-$156,500,922.00 ' Total tax value of structures in all flood zones $221,076,678.00 (excluding zone x) (Property at risk of flooding - 58.5% of structure value) Utilizing methodology above and applying this information to the risk map, the following ' assumptions can be made: SUMMARY B ' Kill Devil Hills Total Structure Value 3/94 $377 577 600.00 2D ' Structure value in extreme risk areas $105,543,230.00 (Property at extreme risk - 28% of structure value) I Kill Devil Hills Total Structure Value (3/94) $377,577,600.00 Structure value in high risk areas $114,768,448.00 (Property at high risk - 30.4% of structure value) Kill Devil Hills Total Structure Value (3/94) $377,577,600.00 Structure value in moderate risk areas $156,500,922.00 (Property at risk - 41.4% of structure value) Kill Devil Hills Total Structure Value (3/94) $377-9577,600.00 Structure value in low risk areas $ 765,000.00 (Property at risk - .2% of structure value) * Refer to the Hazards Area Map to locate the individual risk zones i.e. extreme, high, moderate, low. LI Appendix S Training Program in the NORTH CAROLINA DAMAGE ASSESSMENT PROCESS STUDENT MATERIALS North Carolina Division of Emergency Management March 1991 C TRAINING PROGRAM IN THE ' NORTH CAROLINA DAMAGE ASSESSMENT PROCESS ' Year after year, natural disasters in North Carolina claim their toll in both lives lost and in properties destroyed. Furthermore, the potential for damage from a disaster is ' increasing. This is due to population growth in high hazard areas, increasing structural values, mounting investments and an ever-increasing economic interdependence be- tween businesses, communities and government. ' In the aftermath of a disaster, an impacted community looks to its government to reestablish services, remove and dispose of debris, and to ultimately ensure long-term restoration to its community. The first step towards this long-term restoration is called damage assessment. When disaster strikes, it is imperative that local and state government officials begin to assess the situation as soon as the immediate response is complete. Only by analyzing ' the disaster's full impact can government respond adequately and effectively. An effective damage assessment will give local government officials vital informa- tion on which to base decisions on prioritizing services, how best to commit resources and even where to begin. Damage assessment also gives local government the information it needs to justify ' requesting supplementary assistance from the state and federal governments. During this course, , local and state government officials and others assigned damage assessment duties are introduced to the importance and purpose of conducting ' and reporting damage assessments following a disaster. In addition, participants are introduced to the vocabulary of damage assessment, the difference between large and small intensity disasters, and the need for estimating damages in terms of numbers and ' dollars. The course will cover operating procedures and standards used to evaluate housing, business, and public sector losses.

Massive ' evacuation of residential area on low ground within 5 to 10 miles of shore possibly required. 4. Hurricane Warning. A hurricane is expected to strike your area within 24 ' hours or less. ' 5. Hurricane Watch: A hurricane may threaten your area within 24 to 36 hours. 6. Storm Surge: The strong winds associated with hurricanes and tropical storms ' cause the sea level to rise above normal tidal heights, with giant wind -driven waves and strong unpredictatable currents, sometimes covering 50 miles. ' 7. Tropical Depression: An area of low pressure rotary circulation of clouds and winds to 38 mph. ' 8. Tropical Storm: Counterclockwise circulation of clouds'and winds 39 mph to 73 mph. The storm is assigned a name. ' D. PRE-LAINDFALL: When the National Weather Service predicts that a hurricane may strike Dare ' County, and when gale force winds reach an area' 300 nautical miles from Dare County, all scheduled time off, vacation, and training shall be cancelled. ' Departmental personnel shall make themselves available immediately for recall to duty. Officers reporting in will have a fully -serviced -ready vehicle with a full gas tank. ' 1. Personnel not already on shift shall muster at the Kill Devil Hills Police Department. Assignments will be made at this muster. All divisions will be required ' to muster with the inclusion of the Animal Control Division. 2. Category IL III, IV and V hurricanes will dictate the division of the ' Department into Two Teams. The Team Commanders shall be the two most senior Officers under the Chief of Police or his Deputy Chief, in the absence of the Chief - of Police. ' 3. Cate gory I hurricanes will not require the division of the Department into ' teams unless an unexpected amount of damage occurs. 1 IJ 4. Detectives will integrate into the Patrol Division and the Administrative personnel will man phones and radios and provide information for the public and , direction to the Department. 5. In the event the Department goes into the Team Concept, each team will be ' on 8 hour shifts. If the storm is one of devastating nature, the recovery period may be days or even weeks. ' E. EVACUATION: The Control Group will notify the Department six hours prior to the Control Group's ' public announcement to evacuate. This alert gives law enforcement time to prepare and make Team assignments. ' 1. Category IV and V hurricanes will dictate that a complete evacuation from the area be conducted by all personnel in an orderly fashion. The evacuation of the Police ' Department will be done in an organized manner. . 2.- Category I and II hurricanes will demand that all Police Department ' personnel remain in the county with few exceptions. 3. Category III hurricane evacuation of law enforcement personnel will be ' determined by the Control Group as per instructions from the Kill Devil Hills Mayor, with few exceptions. ' 4. Equipment to remain behind if Police Department evacuates to be left at P designated sights: 1. Chevrolet Suburban ' 2. Honda A.T.V. (anchored) 3. 5 patrol cars (marked) , 4. Portable lights (3) 5. Portable Honda generator (bums 1 gal. per hr.) _ 6. Cache of gasoline , 7. Cache of water and food (20 persons for one day) 5. Traffic Assignments for Evacuation: ' -- * One man on foot at Ocean Acres Drive and By-pass * One man on foot at Colington Intersection and By-pass ' * One man on foot at Third Street and By-pass * Two, one man patrol cars roving evacuation route 4 .. ' L U J Traffic lights will be put on flashing yellow for caution and officers on foot at the three intersecting areas will direct traffic. The roving patrol officers will attend to traffic backed up on side streets and other problem areas on the evacuation route. Once evacuation has been completed, officers will return to Command Center for further assignment. 6. POLICE EVACUATION: All Police Department personnel not involved in traffic control or routine Police work, will involve themselves with the loading of essential equipment and necessary documents at the direction of the Team Commander of III, IV or V category hurricanes. ' When word comes from the Control Group, the Police Department will convoy to a designated area inland. At the designated area inland, the Department will marshall there for further instructions. 7. RE-ENI TRY: ' After the storm has' subsided, a re -entry -will begin. If bridges have been damaged, re-entry of essential personnel to undertake the task ahead, will be air- lifted in if and when those arrangements can be made i A. If an airlift -entry has to be made, Sworn Officers will be the only members of the Department to make re-entry immediately. Hopefully those members can be lifted to a point which has been designated for the Department's cache of equipment Once on the ground, the Officers will receive orders to conduct reconnaissance of the Town to locate the dead and injured and help coordinate medivacs for the injured. Observation of the devastation of the sector being reconnoitered will be a part of the assignment and reported back to Command Center. PERSONAL HURRICANE PLAN: PURPOSE: Itwill be necessary for all Police Department personnel to be involved in maintaining order during this time of confusion. You will discover that a great deal of stress will fall upon you and your family. 5 I To help reduce this stress, the Department has prepared a Hurricane Plan for each of its members to complete and have approved and placed in personnel file by the Deputy Chief of Police. This plan is basic, but will assists you with your planning. Once you have been called back to duty, you may be unable to return to your residence. 1. All members of the Police Department, Sworn and Non -Sworn are required to participate in filling out and completing a plan. 2. All personnel must have his plan approved and on file with the Deputy Chief of Police. 3. You will be responsible to complete your Hurricane Plan prior to recall to the Department 4. See Division Supervisors for your Personal Hurricane Plan forms and Hurricane Prepareness Information. 0 Section: A PERSONAL HURRICANE PLAN: INTRO D UCTIO N ' Each member of the Kill Devil Hills Police Department shall submit his or her Personal Hurricane Plan. It must be approved by the Deputy Chief of Police and filed. In this plan, ' he or she, must state how their family and property are to be secured before he or she reports for duty when the Police Department goes into the Hurricane Operational Mode. Each individual's Hurricane Plan will be a permanent fixture to his or her file. These plans shall be addressed accordingly, depending upon the category of the storm: CATEGORY: WINDS: STORM SURGE: ' I 74-95 mph 4-5 feet II 96-110 mph 6-8 feet ' III 111-130 mph 9-12 feet IV 131-155 mph 13-18 feet V 156- + 19- + It is imperative that the department member file his plan have it approved by the Deputy ' Chief of Police. Once the officer or member of the department has been placed into the Hurricane Team Status, he or she maybe -unable to return home until many hours after the storm has depleted itself: and the assignment of the member has been completed. ' Hurricanes are stressful events and the member sh ould not be burdened with more than necessary while in the performance of his or her duty. His or her stress level will be ' elevating the moment evacuation starts and will increase as the storm intensifies. If the hurricane is devastating and the aftermath requires long working hours for the teams, the stress level will increase even more. A good plan which secures your family and property ' will help to remove a great deal of worry about personal affairs and make you a more effective employee. ' Personal Hurricane Plan should include: ' * Evacuation Information and * How residence and yard are secured — * Shelter Information and ' * Rations (food and water) to be taken to shelter * In the event you family evacuates or goes to shelter, what special items will they take, bedding, medication, etc. 1 1 Name: Section: I HURRICANE PREPAREDNESS PLAN: Address: EVACUATION INFORMATION: Category I: Category II: Category III: Category IV a v• In the event my family leaves home, their destination will be: In the event I am injured, notify: Name: Phone #: Address: Name: Phone #: .

In the aftermath of a disaster, an impacted community looks to its government to ' reestablish services, remove and dispose of debris, and to ultimately ensure long-term restoration to its community. The first step towards this long-term restoration is called damage assessment. When disaster strikes, it is im erative that local and state government officials begin to assess the situation as soon as the immediate response is complete. Only by analyzing the disaster's full impact can government respond adequately and effectively. An effective damage assessment will give local government officials vital informa- tion on which to base decisions on prioritizing services, how best to commit resources and ' even where to begin. Damage assessment also gives local government the information it needs to justify requesting supplementary assistance from the state and federal governments. ' During this course, local and state government officials and others assigned damage assessment duties are introduced to the importance and purpose of conducting and reporting damage assessments following a disaster. In addition, participants are introduced to the vocabulary of damage assessment, the difference between large and small intensity disasters, and the need for estimating damages in terms of numbers and dollars. The course will cover operating procedures and standards used to evaluate housing, business, and public sector losses.

GENERAL PROVISIONS Sec. 21•7.1. Stormwater manngement. (A) The purpose of this chapter is to: (1) Mitigate damage to property caused by flooding; (2) Reduce existing and future maintenance of and capital expenditures for stormwater drainage systems; (3) Cooperate in the coordination of related goals expressed by state and federal regula- tions and that require certain actions with regard to, but not limited to, stormwater management, soil erosion and sedimentation control and flood plain management and Supp. No. 6 1304 ZONING § 21-7.1 ' (4) Guide growth in an orderly manner consistent with the Kill Devil Hills Land Use ' Plan. (B) For all development, other than one- or two-family dwellings, there shall be provided a comprehensive plan for the proper drainage of all surface water to systems on and off the ' property in question. The design criteria as stated in the following paragraphs or that as may be specified by state or federal agencies, whichever is the most restrictive, will be used. Every reasonable effort will be made to retain a maximum of the runoff on site to the extent feasible ' and practical. The Stormwater Management Plan shall be certified by a North Carolina registered professional engineer for compliance to requirements of this section. ' (C) All surface water drainage into the site being developed or generated on said site must be accommodated in accordance with these guidelines. All surface water drainage leaving the site shall be channelled to points of approved discharge, including but not limited to, a natural , or man-made watercourse, a lake, pond, ditch, stormwater drainage system or other appro- priate and approved points of discharge. ' (D) No surface water shall be channelled or directed into a sanitary sewer or septic tank system. Distances between open ditches and septic tank systems must be specified on the plans and approved by the Dare County Sanitarian. This approval must be obtained by the developer ' prior to approval of the drainage system by the town of Kill Devil Hills. (E) For management and control of stormwater runoff, techniques such as, but not limited to, retention, detention, and infiltration systems will be used. ' (F) The drainage design criteria for open and closed drainage systems shall generally conform to these guidelines, and the most recent editions of the Handbook of Design for ' Highway Surface Drainage Structures prepared by the NC DOT, the American Society of Civil Engineers Manual of Engineering Practice No. 37, and Urban Hydrology for Small Water- sheds (Technical Release No. 55) prepared by the Soil Conservation Service. ' (G) Development plans shall show the flow direction of stormwater on and off the prop- erty; size, slope, invert, and rim elevations of system components and ditch cross sections in , the vicinity of the development and/or to a distance as is necessary to evaluate the impact of runoff to existing surface water drainage systems. ' (H) Drainage calculation, drainage area maps, flood routing calculations, infiltration calculations, storm sewer back water curve calculations, and other information that may be required, from time to time, shall accompany or be a part of site plans submitted. ' (I) Estimated runoff calculations may be computed by the Rational Method (Q=CIA) (see below) or the Soil Conservation Service method in Technical Release No. 55, (SCS TR-56) , "Urban Hydrology for Small Watersheds" or other approved methodologies. Sizing of struc- tures will be based on the Manning Equation. Culverts shall be evaluated for inlet and outlet control as necessary. ' (1) Q means flow in cubic feet per second. (2) C means runoff coefficient. ' Supp. No. 6 1304.1 1 ZONING § 21-7.2 ' runoff hydrograph shall be computed using the tabular method as defined in the most recent edition of SCS TR-55 or other accepted engineering analysis. ' (L) All underground storm sewers, open drainage ways, and related strictures shall be constructed to the applicable provisions of the most recent edition of Roadway Standard Draw- ings and Standard Specifications for Road and Structures produced by the North Carolina Department of Transportation. (M During the construction, preparation, arrangement and installation of improvements ' and facilities in developments, the developer shall maintain each stream, creek, ditch, or channel contiguous to or located within the subdivision in a unobstructed state and shall remove from such watercourses and the banks of the watercourses all debris, logs, timber, and ' other accumulations that would, in time of flood, clog or dam the passage of waters in their downstream course. Installation of appropriately sized conduit, culverts, bridges or other required structures shall not be constructed in a way which will obstruct the flow of drainage. ' (N Responsibility for maintenance. During the development of a site, the person con- ducting the land -disturbing activity shall install and maintain all temporary and permanent ' erosion and sedimentation control measures as required by the approved plan or any provision of this chapter, the Act, or any order adopted pursuant to this chapter or the Act. After site development, the land owner or person in possession or control of the land shall install and/or maintain all necessary permanent erosion and sediment control measures, except those mea- sures installed within a road or street right-of-way or easement accepted for maintenance by a governmental agency. ' (0) Additional measures. Whenever the town determines that significant sedimentation is occurring as a result of land -disturbing activity, despite application and maintenance of protective practices, the person conducting the land -disturbing activity will be required to and ' shall take additional protective action. (P) In all cases, including one- and two-family dwellings, the developer shall be required ' to provide culvert pipes, and swales. (Ord. No. 91-08, 11-18-91) ' Sec. 21.7.2. Soil erosion and sedimentation control (A) Purpose. The purpose of this section is to: ' '1) Regulate certain land -disturbing activity to control accelerated erosion and sedimen- tation in order to prevent the pollution of water and other damage to lakes, water- courses, and other public and private property by sedimentation. ' (2) Establish procedures through which these purposes can be fulfilled. ' (B) Scope and exclusions. This section shall apply to land -disturbing activities undertaken by any person, with the following exclusions: (1) Those undertaken on agricultural land for the production of plants and animals useful to man, including, but not limited to, forage and sod crops, grain and feed crops, I Supp. No. 4 1305 § 21-7.2 KILL DEVIL HILLS TOWN CODE ;# tobacco, cotton and peanuts, dairy animals and dairy products, poultry and poultry ' products, livestock, including beef cattle, sheep, swine, horses, ponies, mules or goats, including the breeding and grazing of any or all such animals, bees and apiary , products, fur animals; (2) Those undertaken on forestland for the production and harvesting of timber and timber products and which are conducted in accordance with Forest Practice Guide- ' lines Related to Water Quality (best management practices) as adopted by the De- partment. If land -disturbing activity undertaken on forestland for the production and harvesting of timber and timber products is not conducted in accordance with Forest ' Practice Guidelines Related to Water Quality, the provisions of this chapter shall apply to such activity and any related land -disturbing activity on the tract; and ' (3) Activity undertaken by persons as defined in G.S. 113A-52 (8) who are otherwise regulated by the provisions of The Mining Act of 1971, G.S. 74-46 through G.S. 74-68; and ' (4) Land -disturbing activity over which the state has exclusive regulatory jurisdiction as provided in G.S. 113A 56(a). ' (C) General requirements. (1) Plan required. No person shall initiate any land -disturbing activity which uncovers more than one-half contiguous acre without having an erosion control plan approved by the town. (2) Protection of property. Persons conducting land -disturbing activity shall take all rea- sonable measures to protect all public and private property from damage caused by such activity. , (3) More restrictive rules shall apply. Whenever conflicts exist between federal, state, or local laws, ordinances, or rules, the more restrictive provision shall apply. ' (D) Basic control objectives. An erosion and sedimentation control plan may be disap- J P Y proved pursuant to subsection (o) if the plan fails to address the following control objectives: , (1) Identify critical areas. On -site areas which are subject to severe erosion, and offsite areas which are especially vulnerable to damage from erosion and/or sedimentation, are to be identified and receive special attention. , (2) Limit time of exposure. All land -disturbing activity is to be planned and conducted to limit exposure to the shortest feasible time. , (3) Limit exposed areas. All land -disturbing activity is to be planned and conducted to minimize the size of the area to be exposed at any one time. (4) Control surface water. Surface water runoff originating upgrade of exposed areas ' should be controlled to reduce erosion and sediment loss during the period of expo- sure. Supp. No. 4 1306 ' ' ZONING § 21-7.2 (5) Control sedimentation. All land -disturbing activity is to be planned and conducted so as to prevent off -site sedimentation damage. ' (6) Manage stormwater runoff. When the increase in the velocity of stormwater runoff resulting from a land -disturbing activity is sufficient to cause accelerated erosion of the receiving watercourse, plans are to include measures to control the velocity at the point of discharge so as to minimize accelerated erosion of the site and increased sedimentation of the stream. ' (E) Mandatory standards for land -disturbing activity. No land -disturbing activity subject to the control of this section shall be undertaken except in accordance with the following mandatory standards: ' (1) Buffer zone. .:(a) No land -disturbing activity during periods of construction or improvement to ' land shall be permitted in proximity to a lake or natural watercourse unless a buffer zone is provided along the margin of the watercourse of sufficient width to confine visible siltation within the twenty-five (25) percent of the buffer zone nearest the land -disturbing activity. Waters that have been classified as trout waters by the Environmental Management Commission shall have an undis- turbed buffer zone twenty-five (25) feet wide or of sufficient width to confine ' visible siltation within the twenty-five (25) percent of the buffer zone nearest the land -disturbing activity, whichever is greater. Provided, however, that the town may approve plans which include land -disturbing activity along trout waters when the duration of said disturbance would be temporary and the extent of the disturbance would be minimal. This subsection shall not apply to a land -disturbing ' activity in connection with the construction of facilities to be located on, over, or under a lake or natural watercourse. (b) The twenty -five-foot minimum width for an undisturbed buffer zone adjacent to ' designated trout waters shall be measured horizontally from the top of the bank. (c) Where a temporary and minimal disturbance is permitted as an exception by subsection (E) (1) (a) of this section, land -disturbing activities in the buffer zone ' adjacent to designated trout waters shall be limited to a maximum of ten (10) percent of the total length of the buffer zone within the tract to be distributed such that there is not more than one hundred (100) linear feet of disturbance in ' each one thousand (1,000) linear feet of buffer zone. Larger areas may be dis- turbed with the written approval of the planning director. (d) No land -disturbing activity shall be undertaken within a buffer zone adjacent to ' designated trout waters that will cause adverse temperature fluctuations, as set forth in 15 NCAC 2B.0211 "Fresh Surface Water Classification and Standards," ' in these waters. (2) Graded slopes and fills. The angle for graded slopes and fills shall be no greater than the angle which can be retained by vegetative cover or other adequate erosion, control devices or structures. In any event, slopes left exposed shall, within thirty (30) working I Supp. No. 4 1307 § 21-7.2 HILL DEVIL HILLS TOWN CODE days of completion of any phase of grading, be planted or otherwise provided with ground cover, devices, or structures sufficient to restrain erosion. (3) Ground cover. Whenever land -disturbing activity is undertaken on a tract comprising more than one-half acre, if more than one-half contiguous acre is uncovered, the person conducting the land -disturbing activity shall install such sedimentation and erosion control devices and practices as are sufficient to retain the sediment gener- ated by the land -disturbing activity within the boundaries of the tract during con- struction upon and development of said tract, and shall plant or otherwise provide a permanent ground cover sufficient to restrain erosion after completion of construction or development. Except as provided in subsection (F) (2) (e) of this section, provisions for a ground cover sufficient to restrain erosion must be accomplished within thirty (30) working days or one hundred twenty (120) calendar days following completion, whichever period is shorter. (4) Prior plan approval. No person shall initiate any land -disturbing activity if more than one-half contiguous acre is to be uncovered unless, thirty (30) or more days prior to initiating the activity, an erosion and sedimentation control plan for such activity is filed with and approved by the town. (F) Design and performance standards. (1) Except as provided in section (F) (2) (b) of this section erosion and sedimentation control measures, structures, and -devices shall be so planned, designed, and con- structed as to provide protection from the calculated maximum peak rate of runoff from the ten-year storm. Runoffrates shall be calculated using the procedures in the USDA, Soil Conservation Service's "National Engineering Field Manual for Conser- vation Practices," or other acceptable calculation procedures. (2) In high quality water (HQW) zones the following design standards shall apply: (a) Uncovered areas in high quality water (HQW) zones shall be limited at any time to a maximum total area within the boundaries of the tract of twenty (20) acres. Only the portion of the land -disturbing activity within a HQW zone shall be governed by this section. Larger areas may be uncovered within the boundaries of the tract with the written approval of the planning director. (b) Erosion and sedimentation control measures, structures, and devices within HQW zones shall be so planned, designed, and constructed to provide protection from the calculated maximum peak rate of runoff of the twenty -five-year storm which produces the maximum peak rate of runoff as calculated according to procedures in the United States Department of Agriculture Soil Conservation Service's "Na- tional Engineering Field Manual for Conservation Practices," or according to procedures adopted by any other agency of this state or the United States or any generally recognized organization or association. (c) Sediment basins within HQW zones shall be designed and constructed such that the basin will have a settling efficiency of at least seventy (70) percent for the forty (40) micron (0.04 mm) size soil particle transported into the basin by the Supp. No. 4 1308 J P n ZONING § 21-7.2 runoff of that two-year storm which produces the maximum peak rate of runoff as calculated according to procedures in the United States Department of Agricul- ture Soil Conservation Services "National Engineering Field Manual for Con- servation Practices" or according to procedures adopted by any other agency of this state or the United States or any generally recognized organization or asso- ciation. (d) Newly constructed open channels in HQW zones shall be designed and con- structed with side slopes no steeper than two (2) horizontal to one (1) vertical if a vegetative cover is used for stabilization unless soil conditions permit a steeper slope or where the slopes are stabilized by using mechanical devices, structural devices or other acceptable ditch liners. In any event, the angle for side slopes shall be sufficient to restrain accelerated erosion. (e) Ground cover sufficient to restrain erosion must be provided for any portion of a ' land -disturbing activity in a HQW zone within fifteen (15) working days or sixty (60) calendar days following completion of construction or development, which- ever period is shorter. ' (G) Stormwater outlet protection. (1) Persons shall conduct land -disturbing activity so that the post construction velocity of ' the ten-year storm runoff in the receiving watercourse to the discharge point does not exceed the greater of - (a) The velocity established by the table in paragraph (4) of this section; or (b) The velocity of the ten-year storm runoff in the receiving watercourse prior to development. ' If conditions (a) or (b) of this paragraph cannot be met, then the receiving watercourse to and including the discharge point shall be designed and constructed to withstand ' the expected velocity anywhere the velocity exceeds the "prior to development" ve- locity by ten (10) percent. ' (2) Acceptable management measures. Measures applied alone or in combination to sat- isfy the intent of this section are acceptable if there are no objectionable secondary consequences. The commission recognizes that the management of stormwater runoff ' to minimize or control downstream channel and bank erosion is a developing tech- nology. Innovative techniques and ideas will be considered and may be used when shown to have the potential to produce successful results. Some alternatives are to: ' (a) Avoid increases in surface runoff volume and velocity by including measures to promote infiltration to compensate for increased runoff from areas rendered im- pervious; (b) Avoid increases in stormwater discharge velocities by using vegetated or rough- ened swales and waterways in lieu of closed drains and high velocity paved ' sections; I Supp. No. 4 1309 § 21-7.2 HILL DEVIL HILLS TOWN CODE (c) Provide energy dissipators at outlets of storm drainage facilities to reduce flow velocities at the point of discharge. These may range from simple rip -rapped sections to complex structures; (d) Protect watercourses subject to accelerated erosion by improving cross sections and/or providing erosion -resistant lining. (3) Exceptions. This rule shall not apply where it can be demonstrated that stormwater discharge velocities will not create an erosion problem in the receiving watercourse. (4) The fallowing is a table for maximum permissible velocity for storm water discharges: Maximum permissible velocities Material F.P.S. M.P.S. Fine sand (noncolloidal) 2.5 .8 Sandy loam (noncolloidal) 2.5 .8 Silt loam (noncolloidal) 3.0 .9 Ordinary firm loam 3.5 1.1 Fine gravel 5.0 1.5 Stiff clay (very colloidal) 5.0 1.5 Graded, loam to cobbles (noncolloidal) 5.0 1.5 Graded, silt to cobbles (colloidal) 5.5 1.7 Alluvial silts (noncolloidal) 3.5 1.1 Alluvial silts (colloidal) 5.0 1.5 Coarse gravel (noncolloidal) 6.0 1.8 Cobbles and shingles 5.5 1.7 Shales and hard pans 6.0 1.8 Source —Adapted from recommendations by Special Committee on Irrigation Re- search, American Society of Civil Engineers, 1926, for channels with straight align- ment. For sinuous channels, multiply allowable velocity by 0.95 for slightly sinuous, by 0.9 for moderately sinuous channels, and by 0.8 for highly sinuous channels. (Id) Borrow and waste areas. When the person conducting the land -disturbing activity is also the person conducting the borrow or waste disposal activity, areas from which borrow is obtained and which are not regulated by the provisions of the Mining Act of 1971, and waste areas for surplus materials other than landfills regulated by the department's division of solid waste management shall be considered as part of the land -disturbing activity where the borrow material is being used or from which the waste material originated. When the person conducting the land -disturbing activity is not the person obtaining the borrow and/or disposing of the waste, these areas shall be considered a separate land -disturbing activity. (I) Access and haul roads. Temporary access and haul roads, other than public roads, constructed or used in connection with any land -disturbing activity shall be considered a part of such activity. (J) Operations in lakes or natural watercourses. Land -disturbing activity in connection with construction in, on, over, or under a lake or natural watercourse shall be planned and I r Supp. No. 4 1310 ' C ZONING § 21-7.2 conducted in such a manner as to minimize the extent and duration of disturbance of the stream channel. The relocation of a stream, where relocation is an essential part of the ' proposed activity, shall be planned and executed so as to minimize changes in the stream flow of characteristics, except when justification for significant alteration to flow characteristic is provided. (I) Responsibility for maintenance. During the development of a site, the person con- ducting the land -disturbing activity shall install and maintain all temporary and permanent erosion and sedimentation control measures as required by the approved plan or any provision ' of this section, the Act, or any order adopted pursuant to this section or the Act. After site development, the land owner or person in possession or control of the land shall install and/or maintain all necessary permanent erosion and sediment control measures, except those mea- sures installed within a road or street right-of-way or easement accepted for maintenance by a governmental agency. ' (L) Additional measures. Whenever the town determines that significant sedimentation is occurring as a result of land -disturbing activity, despite application and maintenance of protective practices, the person conducting the land -disturbing activity will be required to and shall take additional protective action. (M) Existing uncovered areas. ' (1) All uncovered areas existing on the effective date of this chapter which resulted from land -disturbing activity, exceeding one-half contiguous acre, are subject to continued accelerated erosion, and are causing off -site damage from sedimentation, shall be. ' provided with a ground cover or other protective measures, structures, or devices sufficient to restrain accelerated erosion and control off site sedimentation. (2) The town will serve upon the landowner or other person in possession or control of the . land a written notice of violation by certified mail, return receipt requested, or other means reasonably calculated to give actual notice. The notice will set forth the mea- sures needed to comply and will state the time within which such measures must be ' completed. In determining the measures required and the time allowed for compli- ance, the authority serving notice shall take into consideration the economic feasi- bility, technology, and quantity of work required, and shall set reasonable and at- tainable time limits of compliance. (3) The town reserves the right to require preparation and approval of an erosion control ' plan in any instance where extensive control measures are required. (4) This rule shall not require ground cover on cleared land forming the future basin of a planned reservoir. (N Permits. (1) No person shall undertake any land -disturbing activity subject to this chapter without first obtaining a permit from the town except that no permit shall be required for any land -disturbing activity: ' (a) For the purpose of fighting fires; I Supp. No. 4 1311 § 21-7.2 KILL DEVIL HILLS TOWN CODE M For the stock piling of raw or processed sand, stone, or gravel in material pro- cessing plants and storage yards, provided that sediment control measures have been utilized to protect against off -site damage; or (c) That does not exceed five thousand five hundred (5,500) square feet in surface area disturbed. In determining the area, contiguous lands under one (1) or diverse ownership being developed as a unit will be aggregated. (NOTE: THIS EXCLUSION FROM PERMITS SHOULD ALLOW LAND -DISTURBING AC- TIVITIES FOR CONSTRUCTION OF A SINGLE FAMILY RESIDENCE ON A SINGLE LOT, BUT MAY NOT EXCEED ONE-HALF ACRE.) (2) The town may establish a fee if considered necessary. (0) Erosion and sedimentation control plans. (1) An erosion control plan shall be prepared for all land -disturbing activities subject to this chapter whenever the proposed activity is to be undertaken on a tract comprising more than one-half acre, if more than one-half contiguous acre is to be uncovered. The plan shall be filed with the town and the Dare County Soil and Water Conservation District, at least thirty (30) days prior to the commencement of the proposed activity. (2) Persons conducting land -disturbing activity which uncovers one-half or more contig- uous acres shall file one (1) copy of the erosion control plan with the town at least thirty (30) days prior to beginning such activity and shall keep another copy of the plan on file at the job site. After approving the plan, if the town either upon review of such plan or on inspection of the job site, determines that a significant risk of accelerated erosion or off -site sedimentation exists, the town will require a revised plan. Pending the preparation of the revised plan, work shall cease or shall continue under conditions outlined by the appropriate authority. (3) Erosion control plans may be disapproved unless accompanied by an authorized state- ment of financial responsibility and ownership. This statement (see Appendix C) shall be signed by the person financially responsible for the land -disturbing activity or his attorney in fact. The statement shall include the mailing and street addresses of the principal place of business of the person financially responsible and of the owner of theland or their registered agents. If the person financially responsible is not a resident of North Carolina, a North Carolina agent must be designated in the state- ment for the purpose of receiving notice of compliance or noncompliance with the plan, the Act, this chapter, or rules or orders adopted or issued pursuant to this chapter. (4) The Dare County Soil and Water Conservation District within twenty (20) days of receipt of any plan, or within such additional time as may be prescribed by the town, shall review such plan and submit its comments and recommendations to the town. Failure of the soil and water conservation district to submit its comments and rec- ommendations within twenty (20) days or within the prescribed additional time will not delay final action of the plan. 0 1 Supp. No. 4 1312 ' 1 ZONING § 21-7.2 ' (5) The Kill Devil Hills Department of Planning and Development will review each complete plan submitted to them and within thirty (30) days of receipt thereof will ' notify the person submitting the plan that it has been approved, approved with modifications, approved with performance reservations, or disapproved. Failure to approve or disapprove a complete erosion and sedimentation control plan within ' thirty (30) days of receipt shall be deemed approval. Denial of a plan will specifically state in writing the reasons for denial. The town must approve or deny a revised plan within fifteen (15) days of receipt, or it is deemed to be approved. If, following com- mencement of a land -disturbing activity pursuant to an approved plan, the town determines that the plan is inadequate to meet the requirements of this section, the town may require such revisions as are necessary to comply with this section. ' (6) Any plan submitted for a land -disturbing activity for which an environmental docu. ment is required by the North Carolina Environmental Policy Act (G.S. 113A-1 et ' seq.) shall be deemed incomplete until a complete environmental document is avail- able for review. The town shall promptly notify the person submitting the plan that the thirty -day time limit for review of the plan pursuant to subsection (0) (5) of this ' section shall not begin until a complete environmental document is available for review. (7) The plan required by this section shall contain architectural and engineering draw- ' ings, maps, assumptions, calculations, and narrative statements as needed to ade- quately describe the proposed development of the tract and the measures planned to t comply with the requirements of this section. Plan content may vary to meet the needs of specific site requirements. Detailed guidelines for plan preparation may be obtained from the town on request. ' (8) An erosion control plan may be disapproved upon a finding that an applicant, or any parent or subsidiary corporation if the applicant is a corporation: ' (a) Is conducting or has conducted land -disturbing activity without an approved plan, or has received notice of violation of a plan previously approved by the commission or a local government pursuant to the Act and has not complied with ' the notice within -the time specified in the notice; (b) Has failed to pay a civil penalty assessed pursuant to the Act or a local ordinance adopted pursuant to the Act which is due and for which no appeal is pending; ' (c) Has been convicted of a misdemeanor pursuant to G.S.113A-64(b) or any criminal provision of a local ordinance adopted pursuant to the Act; or (d) Has failed to substantially comply with state rules or local ordinances and reg- ulations adopted pursuant to the Act. For purposes of subsection (8), above, an applicant's record may be considered for only ' the two (2) years prior to the application date. (9) Applications for amendment of an erosion control plan in written and/or graphic form may be made at any time under the same conditions as the original application. Until ' such time as the amendment is approved by the town, the land -disturbing activity Supp. No. 4 1313 § 21-7.2 KILL DEVIL HILLS TOWN CODE ' shall not proceed except in accordance with the erosion control plan as originally approved. ' (10) Any person engaged in land -disturbing activity who fails to file a plan in accordance with this section, or who conducts a land -disturbing activity except in accordance with ' provisions of an approved plan shall be deemed in violation of this section. (P) Appeals. (1) Except as provided in subsection (P) (2) of this section the appeal of a disapproval or ' approval with modifications of a plan shall be governed by the following provisions: (a) The disapproval or modification of any proposed erosion control plan by the town , shall entitle the person submitting the plan to a public hearing if such person submits written demand for a hearing within fifteen (15) days after receipt of a ' written notice of disapproval or modifications. (b) Hearings held pursuant to this section shall be conducted by the planning board within twenty (20) days after the date of the appeal or request for a hearing. ' (c) The planning board shall make recommendations to the board within ten (10) days after the date of the hearing on any erosion control plan. (d) The board of commissioners will render its final decision on any erosion control ' plan upon which a hearing is requested within ten (10) days of receipt of the recommendations from the planning board. (e) If the board of commissioners upholds the disapproval or modification of a pro- ' posed soil erosion and sedimentation control plan following the hearing, the applicant shall then be entitled to appeal that decision to the North Carolina Sedimentation Control Commission as provided in section 113A-61(c) of the Gen- , eral Statutes and Title 15 NCAC 4B.0018(b). (2) In the event that an erosion control plan is disapproved pursuant to subsection (0) (8) of this section, the town shall notify. the director of the division of land resources of ' such disapproval within ten (10) days. The town shall advise the applicant and the director in writing as to the specific reasons that the plan was disapproved. The applicant may appeal the town disapproval of the plan pursuant to subsection (0) (8) ' of this section directly to the commission. (Q) Inspections and investigations. , (1) Agents, officials, or other qualified persons authorized by the town will periodically inspect the sites of land -disturbing activity to determine compliance with the Act, this , section, or rules or orders adopted or issued pursuant to this section, and to determine whether the activity is being conducted in accordance with an approved plan and whether the measures required in the plan are effective in controlling erosion and ' sediment resulting from land -disturbing activity. Notice of the right to inspect shall be included in the notification of plan approval. (2) If, through inspection, it is determined that a person engaged in land -disturbing ' activity has failed to comply with the Act, this section, or riles, or orders adopted or ' Supp. No. 4 1314 IZONING § 21-7.2 ' issued pursuant to this section, or has failed to comply with an approved plan, a notice of violation shall be served upon that person by registered or certified mail or other ' means reasonably calculated to give actual notice. The notice shall set forth the measures necessary to achieve compliance with the plan, specify a reasonable time period within which such measures must be completed, and warn that failure to ' correct the violation within the time period will result in the assessment of a civil penalty or other enforcement action. However, no time period for compliance need be given for failure to submit an erosion control plan for approval or for obstructing, ' hampering or interfering with an authorized representative while in the process of carrying out his official duties. If the person engaged in land -disturbing activity fails to comply within the time specified, enforcement action shall be initiated. ' (3) The town shall have the power to conduct such investigation as it may reasonably deem necessary to carry out its duties as prescribed in this section, and for this ' purpose to enter at reasonable times upon any property, public or private, for the purpose of investigating and inspecting the sites of any land -disturbing activity. No person shall refuse entry or access to any authorized representative or agent of the ' town who requests entry for purposes of inspection, and who presents appropriate credentials, nor shall any person obstruct, hamper, or interfere with any such repre- sentative while in the process of carrying out his official duties. (4) The town shall also have the power to require written statements, or the filing of reports under oath, with respect to pertinent questions relating to land -disturbing ' activity. (R) Penalties. ' (1) Civil penalties. (a) Any person who violates any of the provisions of this section, or rules or orders adopted or issued pursuant to this section, or who initiates or continues a land - disturbing activity for which an erosion control plan is required except in accor- dance with the terms, conditions, and provisions of an approved plan, shall be ' subject to a civil penalty of not more than five hundred dollars ($500.00), except that the penalty for failure to submit an erosion control plan shall be as provided in subdivision c. of this subsection. No penalty shall be assessed until the person ' alleged to be in violation has been notified of the violation by registered or certified mail, return receipt requested, or other means reasonably calculated to give actual notice. The notice shall describe the violation with reasonable par- ticularity, specify a reasonable time period within which the violation must be corrected, and warn that failure to correct the violation within the time period will result in the assessment of a civil penalty or other enforcement action. ' However, no time period for compliance need be given for failure to submit an erosion control plan for approval or for obstructing, hampering or interfering with an authorized representative while in the process of carrying out his official ' duties. Each day of continuing violation shall constitute a separate violation. I Supp. No. 4 1315 § 21-7.2 KILL DEVIL HILLS TOWN CODE (b) The board of commissioners shall determine the amount of the civil penalty to be assessed under this subsection and shall make written demand for payment upon the person in violation, and shall set forth in detail a description of the violation for which the penalty has been imposed. In determining the amount of the pen- alty the governing body shall consider the degree and extent of harm caused by the violation and the cost of rectifying the damage. Notice of the assessment shall be by registered or certified mail or other means reasonably calculated to give actual notice. If payment is not received or equitable settlement reached with thirty (30) days after demand for payment is made the matter shall be referred to the town attorney for institution of a civil action in the name of the town in the appropriate division of the General Courts of Justice for recovery of the penalty. (c) Any person who fails to submit an erosion control plan for approval as required by this section shall be subject to a single, noncontinuing civil penalty of not more than one thousand dollars ($1,000.00). Any person who is subject to a civil penalty under this subsection may be subject to additional civil penalties for violation of any other provision of this section, or rules or orders adopted or issued pursuant to this section. (d) Civil penalties collected pursuant to this chapter shall be used or disbursed as directed by G.S. 113A-64(a). (2) Criminal penalties. Any person who knowingly or willfully violates any provision of this section, or rule or order adopted or issued pursuant to this section, or who know- ingly or willfully initiates or continues a land -disturbing activity for which an erosion control plan is required except in accordance with the terms, conditions, and provi- sions of an approved plan, shall be guilty of a misdemeanor punishable by imprison- ment not to exceed ninety (90) days, or by a fine not to exceed five thousand dollars ($5,000.00), or by both, in the discretion of the court under GS 113A-64(b). (S) Injunctive 1-elief. (1) Whenever the governing body has reasonable cause to believe that any person is violating or threatening to violate this section or any rule or order adopted or issued pursuant to this section, or any term, condition, or provision of an approved erosion control plan, it may, either before or after the institution of any other action or proceeding authorized by this section, institute a civil action in the name of the town for injunctive relief to restrain the violation or threatened violation. The action shall be brought in the Superior Court of Dare County. (2) Upon determination by a court that an alleged violation is occurring or is threatened, it shall enter such orders or judgments as are necessary to abate the violation or to prevent the threatened violation. The institution of an action for injunctive relief under this section shall not relieve any party to such proceedings from any civil or criminal penalty prescribed for violation of this section. (T) Severability. If any subsection or subsections of this section is,;are held to be invalid or unenforceable, all other subsections shall nevertheless continue in full force and effect. Supp. No. 4 1316 ZONING § 21-7.3 (U) Effective date. ' November 18, 1991. (t) Revisions.

No. 91-08, 11-18-91) U Appendix 11: Citizens Guide To Lessening Storm Vulnerability F Appendix 11 CITIZENS GUIDE TO LESSENING STORM VULNERABILITY Stormproofing Techniques The most practical stormproofing measures a property owner can institute ' to an existing structure are installation of storm shutters or plywood cut to fit over windows and doors in the event of a hurricane warning. This 'improvement protects the integrity of the "building envelope" from flying debris common in high winds. Other measures include affixing roof rafter tie -down devices to top plates of framing members, increased nailing size ' and schedule for siding and roofing (particularly around perimeter and seams) and elevating structures above flood waters. Updating homeowners and flood insurance policies (flood damage is not covered by homeowners insurance) on an annual basis is another practical measure property owners can undertake. The following pages provide additional information on lessening storm ' vulnerability. 7 u 1 .. HURRICANE WIND HOME SELF INSPECTION Will your house stand up to the forces of a catastrophic hurricane (strong Category 3 or greater)? Here is a check list that can help you make your home more resistant to hurricane force winds. To answer some of these questions may require you to get up into your attic crawl space with a flashlight. You may feel more comfortable with an experienced engineer or contractor inspecting your home. Whatever choice you make, take some time to do this well before the storm strikes. ROOF DESIGN * Low pitched roofs are more vulnerable than steeper roofs because the some factors that make an airplane fly can help lift this roof type off the house. * Is your roof pitched less than 30 degrees from horizontal? _yes _no * Hip roofs seem to reflect winds better than gable designs. Is your roof hipped? _yes _no * Gables of masonry construction seem to perform better. If your roof is gabled, are the gabled ends of masonry construction? _yes no" * If your roof is gabled, are there braces behind the trusses at both ends, holding them in place? __yes _no * If your roof is gabled, are the ends of the trusses along the outside walls attached to the tops of the wall at all points with metal hurricane straps? _yes no DID YOU KNOW? * Steep roofs often experience structural failure at the ridges or gable ends where the wind's suction forces are high. Lower or gradually sloped roofs receive damage at roof corners. ROOF BRACING Are the roof trusses braced independently; that is, are their braces that connect the trusses together rather than the roof sheathing connecting the trusses together? _yes _no Mpi--_ON CONTINUOUS PATH CNN C1CgC M This connection system shovl+s an exainp a"of a h continuous Ioad transfer' path IA''r two-stor-y: ,�; .� house.

Sometimes failure occurs due to installation damage (i.e. small tears left by staple guns or misplaced nails not allowing the next shingle layer to lay flat) ' * Clay tiles - This roof covering is good by apt to shatter if hit by flying debris. Loose tiles can become projectiles and damage others. * Concrete flat tiles - This roof covering also does well if it was well bonded to the mortar on the roof. Tiles that become loose can also become projectiles. * Gravel - This roof performs well if properly maintained, however, gravel can become projectiles in extreme conditions. They should be recoated with asphalt and gravel periodically.

The 75-160 mile per hour winds of a hurricane can extend 1 inland for hundreds of miles. Hurricanes cari spawn tornadoes, which add to the destructiveness of the storm. Floods and flash floods generated by torrential rains also cause damage and loss i of life. Following a hurricane, inland streams and rivers can flood and trigger landslides. i - Z. When a hurricane watch is issued, the best response is to protect your property by boarding up windows, bringing in outside items and being prdpared to evacuate fire area as soon as officials so advise. i 3.

These policies and actions comprise an integrated strategy for reducing death and destruction related to major storm events. For convenience, policies and actions are presented in two general categories according to whether their effect is felt before the storm or after. The easiest way to determine this is to apply one of two questions to each policy or action: 1. Will this policy or action help mitigate storm damage? or 2. Will this policy or action help with post -storm reconstruction? In each category, the party responsible for carrying out the item is identified, and an approxi- mate time frame for seeing it done is suggested. This summary provides a convenient check- list for the Town as it pursues each element of the overall strategy. ■ w■r w �� ■ ■� ■ r� w �� ■ ■■� ■ ws ■ .�i w s „anW'An r w a a rra a a r■ wsw. ■ —s w w —. ■ �, a o■■ ■ ■ar ■ a � ■ w a a way a a awe a w ® a rrr a w ■ a ems. ■ w �■ w i ■ ! 1 ! 1 r I J Wit: I I I I ■ I r ■ i I ■ t i I I r I i I ■ I r I I i ■ I 1 I Policy or Action Responsibility Time 1 The Town shall continue to enforce existing rules and regulations including NC Building Planning and On - Codes, the Flood Damage Prevention Ordinance, Chapter 21 Zoning & utilize policies Development going stipulated in the Land Use Plan.

Copies of the complete Plan are available at the Town's Planning and Development Department. Main Objectives of the Plan This Plan is part of the Town's comprehensive strategy for dealing with the long term consequences of a major storm. More specifically, the mitigation actions set forth in this Plan are intended to: 1. Protect human life and health. 2. Facilitate evacuation. 3. Promote rebuilding and reconstruction in a prompt and orderly manner. 4. Reduce damages to existing and future development. . 5. Reduce damages to existing and future public facilities and structures. 6. Minimize expenditures of public and private money for repetitive repairs and reconstruction. 7. Minimize need for emergency actions associated with storm events which are usually under- taken at public expense. 8. Minimize prolonged business interruptions, especially involving businesses providing critical supplies and services. 9. Assist in maintaining a stable tax base by providing for sound use of land which may be located in storm hazard areas. 10. Lessen exposure of the Town to liability claims. 11. Balance the need to rebuild infrastructure and buildings with the need to preserve and enhance the beaches, dunes and other natural features of the Kill Devil Hills environment. Other Objectives of the Plan In addition to the above -noted primary objectives, there are a number of other beneficial objectives that this Plan helps to achieve, but that do not relate directly to the mitigation of destructive storm effects. These objectives include: 1. Enhance local recreational and open space opportunities including enhancement of public access to beach, ocean and sound. 2. Enhance and restore local, natural ecosystems. 3. Reduce traffic congestion, noise and other transportation generated problems. 4. Enhance the long-term economic vitality of the town. 5. Improve the efficiency in delivery of public services. 6. Protect and improve the aesthetic and scenic characteristics of the town's environment. Citizens Guide to Lessening Storm Vulnerability STORM PROOFING TECHNIQUES The most practical storm proofing measures a property owner can do to an existing structure in the event of a hurricane warning are the installation of: • storm shutters, or • plywood over windows and doors. Other measures that may aid in lessoning storm vulnerability and risk of loss include: • Affixing rafter tie -down devices to top plates of framing members • Increase nailing schedule and size for siding or roofing repairs (particularly around perim- eter and seams) • Elevating structures above flood waters • Videotaping the property, structure and pos- sessions, and • Updating homeowners and flood insurance policies (flood damage is not covered by homeowners insurance) on an annual basis. The following provides additional information on lessening storm vulnerability. HURRICANE WIND HOME SELF INSPECTION Will your house stand up to the forces of a cata- strophic hurricane (strong Category 3 or greater)? Following is a check list that can help you make your home more resistant to hurricane force winds. To answer some of these questions, you may have to get up into your attic with a flashlight. Or, you may feel more comfortable with an experienced engineer or contractor inspecting your home. Whatever choice you make, examine your house thoroughly and make the necessary adjustments before a storm strikes. ROOF DESIGN • Is your roof pitched less than 30 degrees from horizontal? yes —no (Low pitched roofs are more vulnerable than steeper roofs because the same factors that make an airplane fly can help lift this roof type off the house.) • Is your roof hipped? yes no (Hip roofs seem to reflect winds better than gable designs.) • If your roof is gabled, are the gabled ends of masonry construction? yes no (Gables of masonry construction seem to perform better.) • If your roof is gabled, are there braces behind the trusses at both ends, holding them in place? yes no • If your roof is gabled, are the ends of the trusses along the outside walls attached to the tops of the wall at all points with metal hurricane straps? yes no ROOF BRACING • Are the roof trusses braced independently; that is, are there braces that connect the trusses together rather than the roof sheathing connecting the trusses together? yes no ROOF SURFACE What kind of surface covers your roof? • Asphalt or composite shingles - This common roof covering may start tearing off when winds reach 60 mph. Sometimes failure occurs due to installation damage (i.e. small tears left by staple guns or misplaced nails not allowing the next shingle layer to lay flat) • Clay tiles- This roof covering is good but likely to shatter if hit by flying debris. Loose tiles can be- come projectiles and cause even more damage. What This Plan Is and What It Is Not This Plan is not an emergency operations plan (EOP). EOP plans are prepared by the Town and the County to respond on a short term basis to crisis situations, ranging from hazardous waste spills to major storm events. As the EOP name implies, these plans are operational in nature, oftentimes setting emer- gency procedures for marshaling people and equipment in very rapid order to deal with the immediate needs of those persons affected by the emergency event.

In addition, this Plan sets forth post -storm policies and standards to guide reconstruction in a pre -planned, orderly way. Such reconstruction may take months or even years to complete, depending upon the severity and ultimate impact of the storm. • Concrete flat tiles - This roof covering does well if it is well bonded to the mortar on the roof. Tiles that become loose can also become projectiles. • Gravel - This roof performs well if properly main- tained, however, gravel can become projectiles in extreme conditions. They should be recoated with asphalt and gravel periodically. SUB ROOFING MATERIAL Is your subroof material plywood sheathing? yes no ROOFING CONNECTIONS • Is the roofing material nailed or stapled? nailed stapled • Do the nails or staples actually connect the sheathing to the roof trusses? yes no • Do hurricane straps or clips anchor the roof to the walls? yes no Tl� ���E`}f� II If you have a wind turbine on your roof, can it be removed, and the opening capped? yes no (Wind turbines on roofs can be dangerous if not capped and secured during severe winds.) 8 ,(r it N D 0' 8 , il\'' U1, 'E 0 l yl l i+ Do you have hurricane shutters installed on your windows or plan to board up your windows? yes no (Properly installed hurricane shutters or boards keep winds out of the house, which in turn, places less uplift pressure on the roof.) If you answered "no" to many of these ques- tions, you should investigate the feasibility of strengthening your home to survive high winds. Consult a qualified contractor, archi- tect, or professional engineer for further information. The above information concerning Storm Proofing Tech- niques was adapted from material provided by the Division of Public Safety, Emergency Management Program. Additional information can be obtained from the Kill Devil Hills Planning and Development Department. Storm Preparedness Tips Hurricanes can be damaging and life threatening. Paying attention to hurricane warning messages and planning ahead can reduce chances of injury or major property damage. BEFORE THE STORM Plan an evacuation route. Contact the local emergency management office and ask for the community hurricane preparedness plan. This plan should include information on the safest evacuation routes and nearby shelters. Learn safe routes inland. Be ready to drive 20 to 50 miles inland to locate a safe place. Have emergency supplies on hand. • Flashlight and extra batteries • Portable battery -operated radio and extra batteries • First -aid kit and manual • Emergency food and water • Portable can opener • Essential medicines • Cash and credit cards • Sturdy shoes Make arrangements for pets® Pets may not be allowed into emergency shelters for health and space reasons. Contact your local humane society for information on local animal shelters. Why Prepare This Plan Now ? Unless a suitable plan for reconstruction has been prepared preceding a disaster, the pressure and ur- gency to rebuild damaged properties and facilities after the storm may create a pattern of construction and land use even more susceptible to destruction than the previous pattern. Unless a pre -planned effort has been made to correct inappropriate development patterns, reconstruction may be unimaginative and lengthy, and provide inadequate relief from future damaging occurrences. Two Phases of Hazard Mitigation Hazard mitigation occurs in two distinct phases of disaster planning— the pre -disaster phase and the post - disaster reconstruction phase. These two phases may be described as follows: Pre -Disaster Mitigation Pre -disaster mitigation involves the identification of public policies and actions which can be taken today which reduce future disaster impacts, including injury or loss of life, and the extent of damages to public and private property. The overriding goal is to make new development and redevelopment less suscep- tible to future disaster damages. Pre -disaster mitigation offers the opportunity to develop policies and programs in the relative calm between storm events —without the duress and pressure that accompany immediate, post -disaster decision -making. Pre -disaster planning also promotes a more rapid and efficient recovery, while at the same time making the most of post -disaster opportunities for safety improvements. Post -Disaster Mitigation Post -Disaster mitigation involves the implementation of policies to guide the reconstruction of the commu- nity in a way which seeks to eliminate or reduce those development and building practices which make the community especially susceptible to storm damage. The need for post -disaster mitigation is often best understood by the public immediately following a storm event, when the reality of the disaster threat is fresh in people's minds. Following a hurricane or major coastal storm, damage may be widespread. Numer- ous opportunities will be available during reconstruction to promote hazard mitigation, as well as to achieve other local land use objectives. Experience in other coastal states and localities hit by hurricanes indicates that reconstruction and rebuild- ing can occur very quickly and that mechanisms must be put into place prior to the storm which will serve to coordinate and manage the reconstruction process. Such a system will insure that significant opportuni- ties for mitigation are not overlooked or lost in the haste to rebuild, while facilitating swift reconstruction and recovery for those structures or portions of the community not as heavily damaged. Post -disaster mitigation can also be greatly aided by the abundance of technical and financial assistance that is often available. It is important that the mitigation Plan set forth specific policies and actions that position the Town to take advantage of every form of assistance to which the community may be entitled. Finally, post -disaster reconstruction, if handled correctly, is actually pre -disaster mitigation, in terms of the next event. And there will always be a next event. Protect your windows® Permanent shutters are the best protection. A lower -cost approach is to put up plywood panels. Use 1/2" plywood— marine plywood is best —cut to fit each window. Remember to mark which board fits which window. Pre -drill holes every 18" for screws. Trim back dead or weak branches from trees. Maintaining your trees will not only help prevent damage to your house but to your neighbor's property as well. Know the difference between a "hurricane watch and a "hurricane warning." A hurricane watch is issued when there is a threat of hurricane conditions within 24-36 hours. A hurricane warning is issued when hurricane condi- tions (winds of 74 miles per hour or greater, or dangerously high water and rough seas) are ex- pected in 24 hours or less. Check into flood insurance. You can find out about the National Flood Insur- ance Program through your local insurance agent or emergency management office. There is nor- mally a thirty -day waiting period before a new policy becomes effective. (Remember, flood damage is not covered by homeowners insurance) DURING A HURRICANE WATCH • Listen to the radio or television for hurricane progress reports. • Check emergency supplies. • Fuel car. • Bring in outdoor objects such as lawn furniture, toys and garden tools, and anchor objects that cannot be brought inside. • Begin shuttering or boarding up windows. • Turn refrigerator and freezer to coldest settings. Open only when necessary and close quickly. • Review evacuation plan. • Attach boat securely or move it to a designated safe place. Use rope or chain to secure boat to trailer. Use tie -downs to anchor trailer to the ground or house. DURING A HURRICANE WARNING • Listen constantly to the radio or television for official instructions. Make sure you have a battery operated radio, in case power goes out. • Secure buildings by closing and boarding up windows. Remove outside antennas. • If in a mobile home, check tie -downs and evacu- ate immediately. • Store valuables and personal papers in a water- proof container on the highest level of your home. • Avoid elevators. • Stay inside, away from windows, skylights and glass doors. • Store drinking water in clean bathtubs, jugs, bottles and cooking utensils. • Keep a supply of flashlights and extra batteries handy. Avoid open flames, such as candles and kerosene lamps, as a source of light. • If power is lost, turn off major appliances to reduce power surge when electricity is restored If officials indicate evacuation is necessary • Leave as soon as possible. Avoid flooded roads and watch for washed out bridges. • Before leaving, unplug appliances and turn off electricity/propane and the main water valve. • Tell someone outside of the storm area where you are going. • Secure yard furniture, outdoor storage sheds, etc. • Elevate furniture to protect it from flooding. • Bring pre -assembled emergency supplies and warm protective clothing. • Take blankets and sleeping bags to shelter. • Lock up home and leave. — From the Federal Emergency Management Agency, TOWN OF KILL DEVIL HILLS USEFUL NUMBERS General Information ..................480-4000 Planning and Development ......480-4050 Public Works..............................480-4040 Fire Department ........... 9-1-1 or 480-4060 Police Department ....... 9-1-1 or 480-4036 Utilities ........................................ 480-4080 Storm Hazard Mitigation and Post -Disaster Reconstruction Plan Town of Kill Devil Hills, North Carolina 1996 Town of Kill Devil Hills, North Carolina 1996 STORM HAZARD MITIGATION AND POST -DISASTER RECONSTRUCTION PLAN BOARD OF COMMISSIONERS F.
