The first European settlement in North Carolina was located on one of North Carolina's coastal islands, and from the colonial,and revolutionary periods on the coastal - sounds and rivers have served as ports of entry and major routes of commerce. As transportation routes moved inland population and economic centers did also and_the coastal region did not experience the same degree of growth as other areas of the state. However, in more recent years increases in tourism, second home development and industrial locations have created a new growth trend in North Carolina as well as other coastal states. Recent census data indicates that more than half of the nations population is within 50 miles of the beach. This trend led both State and Federal governments to the conclusion that if the vast natural and economic resources represented in the coast were to be managed wisely new institutional frameworks were needed. This realization led directly to the development of a new area of public policy and concern known generally as coastal planning. Coastal planning and -its programs are most vis- ibly and concretely articulated at the Federal.level by the Coastal Zone Manage- ment Act of 1972, and at the State level by the Coastal Area Management Act of 1974. 1.2 LEGISLATIVE INITIATIVES: FEDERAL The Federal effort to promote coastal planning began with the passage of the Coastal -Zone Management Act of 1972 (Public Law 92-583). Its major objective is to encourage.coastal states to develop a management program to guide the pub- lic and private use of lands and waters in the coastal zone. State programs are to be carried out in two phases -.one, development of the management program, and two, actual management of the program in the sense of administrative and regu- latory procedures. North Carolina's coastal program is now in phase two. The Federal Act is administered by .the U.S. Department of Commerce which is author- ized to make grants to coastal states for development and administration on their program. 1 1.3 LEGISLATIVE INITIATIVES: NORTH CAROLINA The origins of the North Carolina Coastal Area Management Act (CAMA) began in the 1969 General Assembly. After enacting the dredge and fill law (now ab- sorbed into CAMA), the General Assembly directed that'a study be made with a view to the preparation of a plan for the development and conservation of the state's coastal resources. At least 4 drafts of proposed legislation were pre- pared with the final draft introduced in the General Assembly in March 1973. After five hearings on the coast, days of floor debates and committee hearings,. the Act was ratified on April 12, 1974, one day before the end of.the session.. CAMA's unique feature is that it is a joint undertaking between local and State. interests. Thiq is accomplished by giving the authority for planning to local governments and delegating to the State the responsibility for defining Areas of Environmental Concern (AEC's). Regulation of development within AEC's is a, State -local effort. Each local government within the 20 county coastal area is. required to prepare a land use plan in accord with guidelines prepared by the Coastal Resources Commision (CRC); a 15 member policy -making body created by the Act. After adoption of the plan by the local government and approval by the CRC, no development within an AEC will be permitted unless it is consistent with the local land use plan. The following paragraphs summarize the 4 major parts of the Act. PART ONE - ORGANIZATION AND GOALS - This part sets out goals of the. Act, defines terms, and establishes the Coastal Resources Commission and the Coastal Resources Advisory Council. The Advisory Council is a 47 member advisory group that provides technical assistance to the CRC. Briefly, the goals .of CAMA are as follows: 1)` To.'provide a management system capable of preserving and managing the natural ecological conditions of the estuarine and barrier dune system, and beaches; 2) to insure that the development or preservation of coastal lands and waters is consistent with their capability to absorb change; 3) to insure the orderly and balanced use and preservation of coastal re- sources on behalf of the State and nation;. 4) to establish planning policies and guidelines.for the use and development of coastal lands and waters. 2 i PART TWO - PLANNING PROCESSES - This part requires the CRC to prepare and adopt guidelines for the preparation of land use plans, which plans will. then serve as guides for the issuance or denial of development permits within AEC's. PART THREE - AREAS OF ENVIRONMENTAL CONCERN - Part 3 requires the CRC to designate AEC's and establish standards for the land uses which may occur within these areas. These standards will be used in conjunction with theland use plans to determine whether or not development will be permitted in an AEC. AEC's will fall within one of the following four categories: Estuarine System, Ocean Hazard Areas, Public Water Supplies, and Fragile Coastal Natural.and Cultural Resource Areas. PART FOUR - PERMIT LETTING AND ENFORCEMENT - This final part of CAMA establishes the administrative procedures for enforcement. Since March 1, 1978, no development is permitted within an Area of Environmental Concern without a permit. Local governments may assume authority for permit letting in AEC's for minor developments, but permit letting authority for major developments is reserved to the.CRC. 1.4 PROGRAM ADMINISTRATION - 1974 TO DATE North Carolina's Coastal Management Program has focused on meeting the requirements of CAMA and the Federal Coastal Zone Management Act. Within the framework of these two statutes, two phases evolved. Phase I is concerned with planning and Phase II with implementation. In accordance with the requirements of Part 2 of CAMA, and assisted by grants from the U.S. Department of Commerce, local governments (including Surf City) began preparation of their land use plans in January of 1975. Final plans from all but 2 of the 52 local governments were submitted to the CRC on May 21, 1976, for review. All of these, including Surf City's, were approved, or approved with conditions. The State Guidelines for Local Planning under which the plans were prepared required that all plans be updated every 5 years. One of the major purposes of the present planning effort is to comply with this requirement. However, since the submission and approval of the first land use plan in 1976, the Guidelines have been revised to reflect a new emphasis on policy formulation by the local governments. 3 1.5 LAND USE PLANNING GUIDELINES These Guidelines are adopted by the CRC and codified in Chapter 15, Subchapter 7B, of the North Carolina Administrative Code. Their purpose is to define a planning process in which local governments will identify land use problems and issues, collect and analyze data bearing on possible solutions, develop alternative strategies for resolving the issues, formulate policies, and select methods of implementation. The minimum requirements of any plan are: (1) a summary of data collection and analysis, (2) an existing land use map, (3) policy discussion, and (4) a land classification map.. Central to each of these requirements is a citizen participation program which seeks to involve residents and property owners in each step to the planning process. The Surf City Land Use Plan is organized within this framework. 1.6 PURPOSES OF LAND USE PLAN The most frequently heard reason for preparing land use plans under the Coastal Area Management Act is that plans are required by the Act and the failure to prepare a plan will result in the State substituting its judgment for that of local government. While this remote possibility does exist, there are better and more practical reasons for preparing a land use plan. As is true for most local units of government in this country, the real property tax is the major generator of revenues for financing services and facilities for the community; and since the amount of the tax is a function of the market value of the property, the ability of the local government to provide services and facilities is largely dependent upon maintaining a strong market value of the land within its juris- diction. Thus, the well-being of the Town's residents will depend in part on how wisely the land resource is governed, so that values and the underlying..tax base remain strong. This issue is at the center of the major purpose of the land use planning process --to influence and direct the determinants of land use change and, thus, of market value, so that the well-being of Town residents is protected and improved. 1.7 PLAN ORGANIZATION The organization of the plan closely follows the outline suggested by the State Guidelines. First, existing land use, natural resource and community facilities data is summarized and analyzed;.included in this step is the 4 preparation of the required existing land use map. Second, land use issues are identified, alternatives suggested, and policies formulated. Finally, the policies are graphically expressed in the land classification map. Supplementary information is included in the technical appendices. 9 2.0 DATA COLLECTION AND ANALYSIS 2.1 PRESENT CONDITIONS The purpose of this subsection is to provide a basic information base to Town officials for making land use decisions. The information is grouped into three categories --population and economy, existing land use, and current plans and policies. 2.1.1 POPULATION AND ECONOMY Towns such as Surf City with resort oriented economies are concerned with two basic segments of their population --the permanent year-round resident, and the seasonal visitor. The permanent population is counted by the U.S. Bureau of the Census every 10 years. The seasonal population is not counted systemati- cally, but several agencies (the Cape Fear Council of Governments, Army Corps of Engineers, and the Town's consulting engineer) have conducted periodic surveys and have achieved results which are considered reliable enough for projection purposes. The following tables summarize the results of the census count and surveys, and the projections made based on those current estimates. U.S. CENSUS COUNT Population % Increase Housing Units % Increase 1970 166 NA 255 NA 1980 390 135 1,037 307 1975 SURVEY BY LOCAL REALTOR Single and Multi -Family Dwelling Units 730 Mobile Homes 365 Motel Units 208 DWELLING UNIT OCCUPANCY SURVEY, BY CAPE FEAR COG - SUMMER 1975 Units Surveyed Occupied % Occupants Occupants/Unit 355 273 77 1,136 4.2 6 s MOTEL UNIT OCCUPANCY. SURVEY BY CAPE FEAR COG - SUMMER 1975 Week Day 1.5 Weekend 3.6 Using these surveys and counts, the Town's consulting engineer developed permanent, peak and average seasonal population projections through the year 2,000. A review of this methodology indicates that the seasonal population projections are reliable; however, the 1980 census count was significantly higher than that estimated and requires modification based on this more recent information. According to the 1980 Census, 78 new dwelling units were added each year between 1970 and 1980. Surveys have shown that approximately 25 percent, or 20, of these new units will be permanently occupied. At the current permanent occupancy rate of 2.5 persons per dwelling unit (1,037 dwelling units divided by 390 per- sons), this would indicate an annual increase of 50 persons to the year-round population, or an additional 500 persons by the year 1990. SUMMARY OF POPULATION PROJECTIONS 1980 % Increase 1990 % Increase 2000 Permanent 390 128 890 56 1390 Peak Seasonal 6010 22 7340 18 8670 Average Seasonal 4310 22 5250 18 6180 Seasonal populations have two direct impacts on the Town --economic and environmental., The economic impact is discussed in the following paragraph. The environmental impact is discussed in several of the sections which follow. How- ever, the importance of the relationship between these two effects cannot -be overstated. While the Towns economy is heavily dependent on the tourist and seasonal resident populations, the main factor that attracts these populations is an attractive environment. Thus, policies and controls which will accommodate increasing population growth, while protecting the environment which encourages this growth, is a major objective of this plan. Segments of the Surf City economy are closely related to the various segments of the population. Motels, restaurants, fishing piers, service stations and other tourist -oriented business are heavily dependent on the tourist season, which generally extends from mid -April through October, with June, July and August 7 being the peak months. A second segment of the economy with significance for Town financial planning is the building business. Most of the current building is for second home, single-family developments. While not a large source of employment, the building of second homes for the seasonal resident adds substan- tially to the.Town's tax base. 2.1.2 EXISTING LAND USE CAMA guidelines require that existing land use be mapped and analyzed with particular attention given to significant compatibility problems, major problems caused by unplanned development, areas experiencing or likely to experience change and areas of environmental concern. Existing land use was mapped from 1978 aerial photography which is available for inspection at Town Hall. Since no previous mapping or analysis of existing land use has been done, no trends can be established. The following table summarizes the results of the land use survey. EXISTING LAND USE SURVEY Land Use Category Acres % of Total Spoil Islands 146 5 Water and Wetlands 2,152 74 Beach 34 1 Developed 4 Residential Conventional 54 Mobile Home 38 Commercial & Institutional 30 Vacant Developable 470 16 TOTAL 2,924 100 Two significant land use patterns are apparent from the preceding table. First, three -fourths of the total land area is in the AEC categories of estuarine systems (water and wetlands) and public trust areas (beaches). Further, an additional 5 percent is subject to Army Corps of Engineers easements (spoil islands), making these areas mostly undevelopable. Thus, at least 80 percent of the total land area in Surf City is subject to severe development restraints from govern- E? ment regulations and physical limitations. The second significant land use pattern -is that almost 80 percent of the developable land is vacant. Most of this undeveloped area lies in the southern portion of Surf City, i.e., south of Charlotte Avenue. This area is characterized by limited commercial uses, almost entirely conventional homes, and large areas of maritime forest. The central portion of the Town, from Charlotte Avenue north to Mecklenburg and including the area extending west over the Intracoastal Waterway, is -a mixture of commercial uses, conventional homes, mobile homes and trailer parks. North of Mecklenburg, the pattern of limited commercial uses and conventional housing is resumed. Because of the small permanent population, what might be considered signifi- cant compatibility problems in other communities are less significant in Surf City. The most apparent example of this is the inconsistent mix of land use. type in the central area. Because the commercial uses are inactive most of the year, conflict is minimized; and, further, most nonresident owners are less concerned about neighboring commercial uses. To some, the most significant compatibility problem is an esthetic one. Several trailer parks and some dilapidated buildings in the central area have created a less than, pleasing appeal to some persons' conception of a resort community. However, this is a ; subjective judgment, and much of this problem has been contained in and around the central business areas. The most serious problems that will impact future land use occur primarily from the increasing tourist traffic. This has resulted in competition for parking spaces, traffic congestion, and increased demand for beach access and related facilities. This problem was discussed in the recently completed Surf City Beach Access Plan which is discussed in the following section and whose policies are incorporated into Section 3.0. An additional problem has been the proliferation of development in and around estuarine waters. Concentrations of septic tanks on fill and soils with poor filtering capacity for sewage disposal have posed a threat to surrounding water quality. While the majority of this type of development has occurred along a series of finger canals north.of the Surf City Town limits, some has occurred along the Intracoastal Waterway in. Surf City. The major area that is likely to experience future change in Surf City, assuming no drastic change in economic demand, will be the southern area from Charlotte Street south to the Surf City -Town of Topsail Beach.corporate limits. 0 If past trends continue, this area should gradually develop with conventional single family homes. As stated above, approximately 75 percent of the total area within the Town's jurisdiction falls within an Area of Environmental Concern. These AEC's are entirely within either the estuarine system or the ocean hazard system. AEC's in the Town's jurisdiction included in the estuarine system are coastal wetlands, estuarine waters, public trust areas, and estuarine shorelines. Collectively, these areas provide critical biological functions which translate into economic benefits. These functions include processes such as water purification, breeding and hatchery areas for fish and wildfowl, and esthetic benefits. Within the ocean hazard area are the frontal dunes and the beaches. The main functions of these two AEC's are protection from excessive erosion and flooding, prevention of encroachment on public beach areas, and reduction of the public costs of inappropriately sited development. The significance of each of these areas is more completely discussed under Section 2.2, CONSTRAINTS. 2.1.3 PLANS, POLICIES AND REGULATIONS The following is a summary of current plans and regulations affecting land use in Surf City. SURF CITY LAND USE PLAN - 1976 - Original CAMA land use plan estab- lishing issues, objectives and standards for future development. TOPSAIL BEACH -SURF CITY 201 FACILITIES PLAN - Prepared in July of 1977 and revised in January 1980, this plan recommends the most environmentally sound, economically feasible alternative for sewage disposal for the Town of Topsail Beach, Surf City and the unincorporated area of Onslow County known as West Onslow Beach. The plan recommends a combination gravity/pressure collection system for transportation of wastewaters to a regional treatment facility on the mainland. A 1.15 MGD capacity stabilization lagoon with spray irrigation -is the recommended method of treatment. Implementation of this plan has been indefinitely postponed because of several recent developments. First, the planned spray irrigation site has been withdrawn by the property owner, International Paper Company. At present, no alternative site has been found. Second,,funding for 201 sewage disposal and other projects for barrier islands has been suspended pending completion of an environmental impact statement required to assess the impact of development on barrier islands. This statement is scheduled for completion in April 1982. Finally, rising construction costs, estimated at $14.9 10 million in 1979 dollars, and severe budget reductions at the state and federal levels may make future construction prohibitively expensive. If all legal, environmental and .financial problems could be resolved immediately, it is doubtful such a system could be in operation in less than five years. Given the complexity of these problems, a much longer period appears likely. SUBDIVISION REGULATIONS - These regulations establish standards for the sub- division of land. Approval procedures are established and standards for required improvements, including requirements for dedicated public access, are set out. SURF CITY COMMUNITY FACILITY STANDARDS - This plan establishes standards for various community facilities, including water supply, storm water management, recreation and solid waste management, and evaluates the Town's facilities against those standards. - SURF CITY BEACH ACCESS PLAN - This plan establishes standards for beach access in the categories of legal availability, parking, facilities, and number of access points and evaluates the Town's access with regard to these points. Recommendations are made for dividing the Town according to intensity of use and providing appropriate facilities according to the degree of use. ZONING ORDINANCE - This ordinance divides the Town into use districts and sets standards for lot size, building height and setbacks and parking require- ments within each district. The Town zoning ordinance and subdivision regulations are enforced by the Town Building Inspector, the Town Planning Board and the Town Council. Each of these.individuals and bodies has authority for various stages of the permit pro- cess for zoning changes or subidivision approval. The building inspector is primarily responsible for permit administration and inspection-, while the Planning Board is responsible for review and recommendation of proposed zoning amendments or new subdivisions. The Town Council retains final authority for denial or approval of amendments or plats. A listing of applicable state and federal regulations is included in the Appendix. 2.2 CONSTRAINTS - LAND SUITABILITY ' The State guidelines for preparation of local land use plans require that many areas that may pose constraints to development be identified and that possible development impacts be discussed. However, many of these areas do not exist in the Town of Surf City and, thus, no discussion is necessary. Such areas include man-made hazard areas, public water supply watersheds, areas with slopes greater than 12 percent (sand dunes could be included in this class, but are discussed under their own class), areas containing unique geologic formations, registered natural landmarks, wooded swamps, and areas with resource potential. Those areas that exist within Surf City's jurisdiction are discussed in.the following paragraphs. 2.2.1 PHYSICAL LIMITATIONS: HAZARD AREAS, SOILS, WATER SUPPLY HAZARD AREAS - Two classes of hazard areas exist in Surf City -- ocean erodible areas and flood prone areas. Previous studies, and recent observa- tion, show relatively minor erosion rates along Surf City's oceanfront. Over the 34 year period between 1938 and 1972, the high water line of Surf City was found to be receding at the rate of one -tenth of a foot per year, while the dune line accreted at the rate of one-half a foot per year. Thus, at present, Surf City's shoreline is not subject to the accelerated erosion occurring futher south in the Town of Topsail Beach. However, because of the northward movement -of the erosion.problem, rates should be monitored closely in Surf City and all setback and flood protection regulations carefully observed. The second type of hazard area is the flood prone area, or that area subject to flooding from a flood of the magnitude that occurs every 100 years. Within the flood prone areas, two distinct zones exist --the V zones, or velocity areas, and the A zones. Within the V zones, buildings are subject to tidal surges with velocity wave action and must be securely fastened to adequately anchored pilings. In the A zone, buildings are subject to less turbulent wave action but may be subject to the forward momentum of breaking waves. In either zone, a building's lowest support- ing structural member must be at or above the minimum base flood elevation. All of Surf City falls within one of these zones, and enforcement of Federal Flood Insurance Administration building regulations within these zones is accomplished by the Surf City Building Inspector. SOILS - According to the Soil Survey of the Outer Banks of,North Carolina, eight dominant soils are found within Surf City's jurisdiction. The approximate locations of these soils are shown on the maps included in the Appendix; however, decisions concerning construction at a particular site should be made only after consultation with a soil scientist and testing of the particular 12 site. The following paragraphs describe the soils most commonly found in. -Surf City. Beach-Foredune Association - This soil is found mainly on the ocean side of.the island and is the long, narrow area comprising the frontal dune and beach. The beaches are flooded daily, and sand sizes range from fine -� to very coarse, but chiefly fine. Because of the tidal flooding, activities other than beach -related recreation are severely limited. _ Carteret Soils - Low - This is a poorly drained, sandy marsh soil found on the sound side of barrier islands. It is flooded daily and has severe limitations -for all types of active, primary uses. Corolla - Fine Sand - These are the soils found on the broad, level -to -slightly -sloping flats behind the foredunes. They have a thin organic layer and are moderately drained throughout, although during the wetter.seasons the water table may be within 12 feet of the surface, thus posing problems for on -site sewage disposal. Dredge - Spoil - These are the soils created by dredging and con- sist mainly of sand and shells. These soils are droughty because of the texture and shell fragments and have a poor filtering capacity for septic tank effluent, thus posing a threat to surrounding estuarine waters. Duckston - Fine Sand - This is a poorly drained soil occupying the flats extending inland from the primary dunes. It has a high percentage of.coarse sand with a depth to water table that may vary from 2 to 5 feet, to several inches, thus posing potential problems for on -site sewage disposal. Madeland - These soils are generally found on the sound side of the island and result from dredging for homesites. They are similar to the Dredge - Spoil soils, with poor filtering capacity for septic tank effluent. Carteret Soils - High - These are the irregularly flooded salt marshes which are covered by tides at least once a month and sometimes weekly. They are significant in the life cycles of many forms of marine habitat and have a low support capacity for structures. Newhan-Corolla Complex - These two soils are consolidated and cannot be separated in most places. They are the low dunes and intervening basins that separate the dunes. The Newhan soils are mostly on the low dunes, with coarse sands, and water tables below 7 feet. The Corolla soils occupy the basins and may have seasonal water tables within 1 to 2 feet of the surface. 13 WATER SUPPLY - Ground water comprises the sole source of water supply for both public and private systems in Surf City. Pender County is underlain by a vast aquifer system, two strata of which are important in the Surf City area as sources of ground water. Pleistocene and recent surficial sands cover the beach areas of the county and constitute the principal water source for most private wells. In the surficial sands, water usually occurs under water table conditions within 15 feet of the land surface, but may be partially confined by clay in the lower part of the aquifer. The productivity of this aquifer is limited primarily by its thickness; it is recharged by rainfall and easily subject to contamina- tion. The Castle Hayne limestone is not extensively used for water supply in the beach area, but is potentailly valuable as a large, long-term supply. The forma- tion begins.at 35 feet below mean sea level, where its waters occur under artesian conditions. Recharge to the Castle Hayne would,.therefore, not be expected to occur in the immediate beach area and its waters would not be as vulnerable to contamination as those of the surficial sands. The quality and quantity of water from the Castle Hayne vary locally. In the Surf City Area, it is generally high in iron, low in chlorides, with a pH of 7-8; at Holly Ridge, indications are -that a specific capacity -of 50-70 gallons per minute per foot drawdown can be obtained. Most attempts to obtain good water from the Castle Hayne in the immediate beach area have proved unsuccessful thus far. 2.2.2 FRAGILE AREAS Significant fragile areas within the Surf City limits are coastal .wetlands, public -trust areas, estuarine waters, dunes and beaches, and the maritime forest. COASTAL WETLANDS_- Coastal wetlands are generally composed of estuarine. tidal marshes and mud flats that cover all but the high sand ridges, dunelands and maritime forests of Surf City along its sounds, creeks and bays. The soils are poorly drained (see 2.2.1, PHYSICAL LIMITATIONS: HAZARD AREAS, SOILS, WATER .SUPPLY) and.are subject to daily and frequent tidal flooding. Tidal marshes are of two types --low tidal and high tidal. Low tidal marshland consists mostly of Spartina alterniflora and is usually subject to inundation by the normal rise 14 and fall of lunar tides. They are particularly significant because of the high yield inorganic detritus which serves as a primary food source for various species of fish and shellfish such as menhaden, shrimp, flounder, oysters and crabs. The roots and rhizomes of Spartina alterniflora serve as waterfowl food, and the stems as wildlife nesting material. Low tidal marshes also help to retard shoreline erosion. High tidal marshland is subject to occasional flooding by tides, including wind tides, and is characterized by Juncus roemarianus and various species of Spartina. These marshes have many of the same functions as the low tidal marshes --food supply for the estuarine system, wildlife habitat,. sediment trap, and deterrent to shoreline erosion. ESTUARINE WATERS Estuarine waters are defined as all the waters of the Atlantic Ocean within the boundary of North Carolina and all the waters of the bays, sounds, rivers, and tributaries thereto seaward of the dividing line between coastal fishing and inland fishing waters. They are the dominant com- ponent of the entire estuarine system and are the most productive natural environment in North Carolina. They support the commercial and sport fishing industries, since these species must spend all or part of their life cycle within the estuarine system to mature and reproduce. The high productivity of the system results from the circulation patterns caused by tidal energy, fresh water. flow and tidal depth. The circulation transports nutrients, propels plankton, spreads seed stages of fish and shellfish, flushes waste from animal and plant life, cleanses the system of pollutants, controls salinity, shifts sediments, and mixes the water to provide a multitude of habitats. Important features are mud and sand flats, eel grass beds, salt marshes, submerged vegetation flats, clam and oyster beds and nursery areas. ESTUARINE SHORELINES.- The importance of estuarine shorelines arises because of the close relationship of each component.of the estuarine ecosystem with all other components. Estuarine shorelines may be defined as non -ocean shorelines which are especially vulnerable to erosion, flooding or other adverse effects of wind and water. While estuarine shorelines are.generally characterized by dry land, their close association with the estuarine system from groundwater and overland flow incorporates them as a vital part of this system Thus development occurring within the estuarine shoreline should be 15 designed and located so as to minimize any adverse effects on surrounding estuarine waters. PUBLIC TRUST AREAS - Generally, public trust areas within the juris- diction of the Town of Surf City are all waters of the Atlantic Ocean and the lands thereunder from the mean high water mark to the seaward limit of the state's jurisdiction; all natural water bodies subject to measurable lunar tides.and A lands thereunder to the mean high water mark; and all navigable natural bodies of water and'lands.thereunder to the mean high water level. A more complete, and controlling, description is found at 15 NCAC 7H.0207. Their significance is that the public has rights in these areas including navigation and recreation. In addition, they support commercial and sports fisheries, have esthetic value, and are important resources for economic development. OCEAN HAZARD AREAS - Ocean hazard areas may be described as areas along Surf City's shoreline where erosion and other adverse effects of wind and water could unreasonably endanger life or property if development is not compatible with natural forces. There are three major landforms which provide protection to development, but which are also in a constant state of change due to the action of wind and waves. These are the beaches, dunes and inlets. There are no inlet areas in Surf City, but the beaches and dunes are critical to protecting; property situated landward of them. The.geographical extent of ocean hazard areas may be better described in terms of areas subject to potential -damage, rather than the physical extent of the particular landform. These areas are the ocean erodible area and the high hazard flood area. The ocean erodible area is the area in which there exists a substantial possibility of excessive erosion and significant shoreline fluctuation. Studies of historical erosion rates indicate that this area extends about 135 feet landward from the first line of stable natural vegetation. High hazard flood areas are subject to high velocity storm waters from a one -hundred year storm (a storm with a one percent chance of being equalled or exceeded in a given year). This,area is identical to the VI-30 Zones identified on the flood insurance rate maps of the Federal Insurance Administration. The geographic extend of this area is an additional 60 feet* landward of the landward boundary of.the ocean erodible area. Thus, the total area covered by ocean hazard areas extends 195 feet landward from the first line 16 of stable natural vegetation. Along Surf City's 5.5 miles of shoreline, this encompasses approximately 130 acres. MARITIME FORESTS - One significant area that is fragile in the sense of its,vulnerability to development is the maritime forest that exists primarily on the western side of N.C. 50 towards the southern limits of Town. It is a highly variable complex of upland, intermediate, and wet forest dominated largely by hardwood tree species. It is thought to be the ultimate phase of forest succession common to the barrier islands and may take up to 1,000 years to develop. The shape and structure of the forest are governed by the inter- action of salt spray kill and soil growing conditions. In some areas, such as those found at Surf City, stunting from salt spray and poorly developed soils have produced a very low canopy, and species usually characteristic of the sub - canopy have become part of the canopy. Some of the subcanopy species are American Holly, yaupon, hornbeam, hop hornbeam, and flowering dogwood. The maritime forest is significant for its esthetic appeal, wind buffering ability, sand trapping capability, and as habitat for many bird and animal species. 2.3 CONSTRAINTS - COMMUNITY FACILITIES 2.3.1 WATER AND SEWER The Surf City water system consists of 2 wells, an elevated storage tank, a groundwater storage tank, and distribution lines providing -service to all residences and businesses within the Town. Both of the wells are located on the mainland between the Intracoastal Waterway and the intersection of Highways 210 and 50. Each well provides a capacity of 350 gallons per minute, or a total of 700 GPM. This provides the Town with a capacity of slightly over 500,000 gallons per day based on a pumping time of 12 hours. This is more than adequate to . handle the approximately 600 customers. Peak demand from the influx of tourists, as well as increased usage during the summer months, reaches approximately 200,000 gallons per day. Thus, even for peak demand periods, total capacity _is over twice that required. Storage is provided by a 100,000 gallon elevated storage tank constructed in 1968 and a 75,000 gallon ground storage tank. Because both of the wells are located on the mainland, little danger exists from possible pollution from septic tank failures. Pollution of.individual.wells has 17 occurred in the Old Settlers Beach area from septic tank failures, with "boil water" notices issued periodically by the local health department. Thus, the mainland location provides not only protection from this source but also from potential saltwater intrusion. While this is not a serious possibility on the beach because of the relatively low rate of withdrawal, there is a greater possi- bility of encountering brackish water. The Town provides chlorination as required by the state standards but does not provide softening, with the result that the "finished" water is slightly hard.,In summary, the water supply, storage, and distribution system of the Town is in conformance with the standards and design guidelines established by the North Carolina Department of Human Resources. Sewage disposal in Surf City is by individual on -site systems, or septic tanks. This method of disposal has created serious water quality problems in a development immediately adjacent to the northern Town limits. Finger canals were excavated, with homes placed on the fill. A joint study undertaken by the North Carolina Departments of Natural Resources and Human Resources and the U.S. EPA concluded that high water tables and poor soil characteristics have resulted in pollution of surrounding estuarine waters, as well as possible contamination of drinking water supplies. While the study focused on the problem in this particu- lar development, it seems apparent that similar soil conditions exist in other areas contiguous to estuarine waters. This conclusion is confirmed in the analysis of soil conditions (Section 2.2.1). The obvious solution to this problem is a central collection and treatment system. However, it appears almost impossi- ble that such a system could be operational in less than five years, or.even ten years (see Section 2.1.3). This constraint indicates that realistic policies for the Town must accept the limitations and hazards of septic tanks as a method of sewage disposal. 2.3.2 ROADS The transportation system in Surf City consists primarily of State Roads NC_50 and 210 which provide access to the beach and major transportation 0 18 routes north and south. These major routes, supplemented by minor collector streets and service roads, are adequate to move traffic even during peak times.. Two related problems may occur during peak hours --parking and evacuation during.. storm warnings. The first problem, parking, is common to all urbanized barrier. islands in North Carolina and will probably be solved only when saturation points are reached and visitors begin to use alternative transportation modes, such as bicycling. The Town established policies for parking in its Beach -Access Plan, and these are incorporated into this plan in Section 3.0. The problem of evacua- tion is provided for in the Town's Evacuation Plan. The possibility of severe traffic jams hindering evacuation is reduced or eliminated by the excellent advance warning systems provided by the National Weather Service and the U.S. Coast Guard. While the bridge over the Intracoastal Waterway provides some inconvenience to motorists when swung for boats, it is sufficient for peak and normal traffic flows. 2.3.3 SCHOOLS Surf City school children attend Topsail High or Topsail Middle Schools located on U.S. 17 about 10 to 15 miles from the Town. A county school bus is available for grades K through 12. 2.3.4 ESTIMATED DEMAND Based on the 1990 population projection of 890 persons, or an increase of 500 persons over the 1980 census count of 390 persons, an additional 29 acres of land would be required to accommodate this increase in new permanent residents. 500 new residents 2 persons per household = 250 new families and needed lots x 5,000 1,250,000 43,560 28.7 29 approximate average lot size needed square footage square feet per acre. acres needed rounded According to the 1980 census count and existing land use survey, about 30 acres of commercial land is used to support the demand justified by the total 19 4,700 average seasonal and permanent population, which is the effective market for tourist oriented economies. Assuming this rate of 278 acres per person (i.e., total permanent and average seasonal) remains constant through 1990, an additional 9.2 acres of commercial land will be required. 1990 permanent population increase 500 1990 average seasonal population increase 940 1990 additional "demand market" 1,440 x 278 square feet = 400,320 43,560 sq. ft. 9.2 acres Thus, a total of 38.2 gross acres of land will be required to accommodate new permanent residents and supporting commercial uses by 1990. Since there are 470 acres of vacant undeveloped land in Surf City, zoned both residentially and commercially, there is more than adequate space for the projected land demand. Because of the considerable excess capacity of the water system, no expansion will be required. Transportation and parking spaces will become more congested but are sufficient to accommodate the additional use. Observance of local health regulations and state requirements for the siting and installation of septic tanks will mitigate the possibility of groundwater contamination or estuarine pollution. at, 3.0 POLICIES Land use policies serve several purposes. First, they act as guides for desired future development and land use changes. In this sense, they may be followed directly or used to interpret the more specific standards set out in Town ordinances, such as the zoning ordinance. When used to interpret ordinances, their function is to provide insight into the desired purpose of a particular regulation, so that its spirit is observed as carefully as its letter. However, policies are not intended to take precedence over Town ordinances and do not have the effect of ordinances. A second purpose is to serve as an expression of Town opinion on land uses permitted within Areas of Environmental Concern. They act as an accepted point of compromise between federal and state agencies and the Town. Broad community needs and needed cooperation from these agencies are expressed in the policies. This purpose is central to the Coastal Area Manage- ment Act's mandate of a land use planning process involving a partnership bretween state and local governments. A third and related use is as a component of state and federal review of permits or grant applications. Development permits must be consistent with local land use plans, as must the expenditure of federal or state funds. These last two purposes pose potential sources of conflict and of opportunity in the land use planning process. The State Guidelines for Land Use Planning require that four major types of policies be formulated where appropriate for the particular locality. These are resource protection, resource production and management, economic and community development, and continuing public participation. Within each of these areas issues are to be defined, alternatives considered and policies and methods of implementation selected. Specific policies are to be stated on certain issues within each of the broad policy areas Small geographical area and relatively few AEC's make many of these issues inapplicable to Surf City (for example, importance of productive agricultural lands or mineral sites). 21 3.1 PUBLIC PARTICIPATION POLICIES The most fundamental objective of democratic practice is to insure that public policies correspond closely with the needs and preferences of.affected citizens, and to prevent government from overstepping the bounds of its limited authority. Such an objective must acknowledge and respect the primary purpose of public participation --increasing the responsiveness and accountability of government to citizens affected by public decisions. Because of the great sensi- tivity.to land use governance, public participation programs should be responsive to the individual property owner as well as special interest groups and the general public. .A public participation program consists of three basic components: (1) education, (2) public participation, and (3) governmental accountability. In preparation, the public must be educated on the basic concepts and process of decision making, and notified of opportunities to participate. The primary objective of the education component is to improve comprehension and communica- tion between affected citizens and local officials. The second component, public participation, requires two things: first, identification of policy options, and second, estimating support from the public for each alternative. The planners' responsibility is to help structure the public debate by highlighting common viewpoints and weeding out policy options that are not feasible on technical, legal or other grounds. The final component, accountability, requires that the rationale for particular policy decisions be explained and opportunities be pro- vided for testing decisions for fairness and responsiveness. Within this framework, several issues must be addressed in establishing policies for public participation. First, who is the "public" toward which participation efforts will be directed. In a typical beach community, the affected may include such groups as property -owning residents, non -property - owning residents (renters and persons living with their partents or relatives), and non-resident property owners (absentee owners). Each of these segments of the public will be affected to some degree by the actions and policies of the Town and each has certain participation rights. The second issue in designing a mechanism for participation is what priorities should be given to each of the - affected groups in allocating time and resources. While each group is entitled to participate and express an opinion, resources for participation are not unlimited and efforts must be directed toward the public most immediately affected. Finally, given the resources available and the social and economic 22 composition of the particular locality, the issue of what methods will most efficiently and effectively gain the needed participation from the various ele- ments of the public must be decided. Methods used by other agencies and local governments in the past have included such diverse techniques as: speakers' bureaus, brochures, new media coverage, depositing information in local public places, public notices, registries of interested individuals, mass mailings, planning information centers, mobile exhibitions, planning workshops, advisory groups, nominal group technique, gaming and simulation, surveys, and systematic distribution of successive draft plans to a panel of citizen reviewers. Many of these methods will have only limited application, if any, to the Town of Surf City. The policies that follow are intended to address the issues defined above and select methods suitable to the Town political character and population size. POLICY - It is the policy of the Town to assure that all resident property owners have equal participation status in land use or other public decisions that may affect them. 3.2 NATURAL RESOURCE POLICIES The Guidelines for local planning require discussion and formulation of policies for a wide range of issues, several of which are not applicable to the Town of Surf City. These issues include productive agricultural lands, commercial forest lands, mineral production areas, and freshwater swamps. CONSTRAINTS TO DEVELOPMENT - Most of the major constraints to development and policies that recognize these constraints fall within the sections that follow. However, one major constraint not specifically covered in the following sections is that imposed by the generally poor soil conditions found within the Town. Failure to recognize this limitation in the past and adequately condition development has resulted in pollution of surrounding estuarine waters and poten- tial health hazards to homeowners. To mitigate similar situations in the future, it shall be the,policy of the Town to insure that new -development complies with all state, federal and local rules concerning the installation and operation of on -site sewage disposal systems; and, further, to the extent that such action does not substantially interfere with an owner's use of his property, the Town's policy shall be to encourage new development to locate in areas with the best on -site disposal capability. 23 AREAS OF ENVIRONMENTAL CONCERN - Among the most important natural resources within Surf City's jurisdiction are the Areas of Environmental Concern which are specifically described in the State Guidelines for Areas of Environmental Concern (15 ACAC 74). While other AEC's may later be nominated and designated as fragile coastal natural resource areas under Section .0500 of the Guidelines, the two areas that predominate within the Town are the estuarine system and the ocean hazard areas. Alternatives to development within Areas of Environmental Concern are strictly limited by the regulations governing use of these areas promulgated under the Coastal Area Management Act. The major policy choices and issues that the Town must consider in developing land use policies for Areas of Environmental Concern are: (1) The degree to which these regulations may restrict or prevent uses within AEC's that may have importance for the entire community, or (2) Whether the regulations are strict enough to protect the natural and protective values found in the Areas of Environmental Concern. The following policies further define these issues and establish the Town's policies toward acceptable land uses within these areas. ESTUARINE SYSTEM - Within the estuarine system are included the coastal wetlands, estuarine waters, estuarine shorelines and public trust areas. The significance of these areas and their descriptions are set out in Section 2.2.2,, FRAGILE AREAS. The overriding issue with regard to establishing land use policies for development within the estuarine system is what uses will interfere least with the interdependent components of the system and will not upset the natural balance and relationship of these components that create public, social and economic values; and, to the extent that uses are permitted, how can these uses be controlled, so that if the natural working system is interefered with, superior public and economic values will be created by the allowed use. The determination of these issues shall be governed by the following policies. ESTUARINE SYSTEM POLICIES (1) It shall be the policy of the Town to give high priority to the protection and coordinated management of the estuarine system, so as to safeguard and perpetuate its biological, social, economic and esthetic values; and to insure that any development occurring within the system is compatible with natural characteristics, so as to minimize the likelihood of significant loss of private property and public resources. 24 (2) Uses shall be those consistent with the above policy, and highest. priority shall be given to uses consistent with the conservation of the estuarine system. Priority will be given to those types of development that require water access but cannot function elsewhere. Examples of acceptable uses include utility easements; fishing piers and docks (public or commercial); structures to prevent erosion; access channels; navigational channels; and private boat ramps. Equal priority will be given to grounds and facilities for public recreation, such as community center buildings, parks and playgrounds and similar facilities operated on a nonprofit basis; and to public or private piers allowable under the Town Zoning Ordinance. POLICY IMPLEMENTATION (1) The Town will enforce as part of its zoning ordinance and map a conservation zone which will permit only those uses consistent with the estuarine system policies. (2) The Town will require that all building construction conform to applicable state building codes and acceptable marine construction techniques. OCEAN HAZARD AREAS - The ocean hazard system consists of two areas -- ocean erodible areas and high hazard areas. The ocean erodible areas are areas in which there exists a substantial possibility of excessive erosion and signifi- cant shoreline fluctuation. The high hazard flood areas are those areas subject to high velocity waters in a storm having a one percent chance of being exceeded or equaled in any given year as identified on flood insurance rate maps or other approved flood elevation data. These areas are considered hazardous because of their susceptibility to change from the constant forces of waves, winds and water upon the unstable sands that form the shore. During storms, these forces are magnified and can cause.significant changes in bordering land forms (dunes and beaches) and to structures located thereon. For this reason, the appropriate location of structures on and near these land forms must be reviewed carefully to avoid their loss or damage. The flexible nature of the land forms, which is hazardous to development located immediately on them, also offers protection to development located behind them. The most essential function of these land forms is their capacity to store sand and dissipate wave and wind energy. Establishing policies for ocean hazard areas is complicated by the fact that many of these areas are in private ownership and, because of their proximity to the beach and ocean, are considered prime building sites. The most critical issue with regard 25 to land use policies is what development controls and building requirements are necessary to insure that construction in these areas does not endanger the lives or property of ocean hazard area property owners or other property owners who may depend upon the protection of land forms associated with the ocean hazard areas,, but will not deprive existing or future property owners of the reasonable use of their property. POLICIES .0) To the maximum extent feasible, and consistent with a property owner's right to reasonable use of his property, uses of land in ocean hazard. areas shall be located, designed and constructed so as to maximize a structure's protection from wind and water and to minimize damage to the protective land forms of dunes and beaches. (2) Preferred erosion control measures to combat oceanfront erosion shall be beach renourishment projects and comprehensive shoreline management, which shall.be preferred over small-scale methods. (3) Newly created dunes shall be aligned, if possible, with existing adjacent dune ridges and shall be of the same general configuration. (4) Adding to dunes shall be accomplished in such a manner that the damage to existing vegetation is minimized. Filled areas shall be immediately replanted or temporarily stabilized until planting can be successfully completed. OCEAN ERODIBLE AREAS - Land uses permitted in the ocean erodible areas shall be those uses permitted by the Town Zoning Ordinance. FLOOD HAZARD AREAS - Land uses shall be those permitted by the Town Zoning Ordinance, which shall include residential, commercial and institutional; provided, however, that all new construction shall meet reasonable requirements of the Federal Flood Insurance Administration as interpreted by the Town Building Inspector. AREAS OF LOCAL CONCERN - In addition to Areas of Environmental Concern, certain areas exist within the Town that have significant esthetic and ecological values*of local concern which could be lessened by careless development. In particular, these areas include the spoil islands found along the Intracoastal Waterway and the maritime forest. The significance of.these areas and their 26 importance is discussed under Section 2.2, FRAGILE AREAS. It shall be the policy of the Town to provide the same degree of protection and priority of use as that afforded the estuarine system areas and to include them in the Conserva- tion Zone in the Town Zoning Ordinance. The major value of the maritime forest is esthetic, although it is an impor- tant component of the barrier island eco-system that provides wildlife habitat and helps to stabilize the soil and sand. The basic issue is how much protection should be provided to these areas --none, total, or limited. Since the.maritime forest does not have*the same significance in terms of protective value that the dune system does, all types of development currently permitted should be allowed but should be controlled so that the least disturbance occurs from development. Therefore, of the three alternatives, limited protection is the preferred choice and*-tne following policy is adopted as a guideline for this. choice. POLICY - It shall be the policy of the Town to encourage the mainte- nance of the existing maritime forest by allowing only that development that will cause the least practicable disruption to the maritime forest cover. All uses currently permitted under the Town Zoning Ordinance will be allowed in areas with maritime forest,.but only if consistent with the above policy. IMPLEMENTATION - The Town will adopt as a part of its zoning ordinance a standard for evaluation of multi -family dwellings that will require the avoid- ance of removal of any part of the maritime forest except.that which is the absolute minimum to allow reasonable use of the site. The Town will adopt as a part of its procedures for the administration of its building code requirements that plans submitted to the building inspector show maritime forest areas and construction procedures that will cause the least practicable disruption to these areas. RECREATIONAL FISHERIES - While the Town has little influence over the quantity of fish caught, it does have a vital. interest in assuring that recreational fishermen have access to the ocean, beaches, and sounds. Access policies to the beach are discussed in following sections. To assure continued access for fishing to the ocean and sound, the Town adopts the following policy. POLICY - It is the policy of the Town that existing and future piers constructed within the Town will be open to the public at reasonable fees and shall be constructed according to the Town's construction standards for piers and docks set out in Chapter 6 of the Town Code. 27 OFF -ROAD VEHICLES - It shall be the policy of the Town to allow vehicles on the beach between September 10 and May 15, provided such vehicles are used only for fishing purposes, cross at designated crossover points, and are manufactured four-wheel drive vehicles. 3.3 DEVELOPMENT POLICIES Surf City's development policies are established to provide a general guide to resolving the basic land use issues of the type, timing, location and density of growth. As such, they are an extension and expansion of the Natural Resource policies, a confirmation of existing policies and ordinances, and an expression of public opinion. Timing of development, or when development will occur, is largely dependent upon the availability of facilities. Location is determined by the desired spatial relationship between land uses and is influ- enced heavily by natural constraints. Density of -development is a function of the ratio of population and number of dwelling units per unit of land. The inter- action of each of these determinants of land use shapes the pattern and character of the Town and its environs. Formulation of policies for each of these issues requires consideration of broad alternative growth patterns and selection of a general growth objective. Citizen input becomes extremely important; and to obtain this input, a survey was conducted of all Town property owners, the results of which are included in the Appendices. ALTERNATIVES - The degree or amount of growth that any community chooses to accept is generally stated in broad terms of no growth, unlimited growth, and controlled growth between the two extremes. A more specific state- ment and definition of these choices is generally expressed by the terms and restrictions of land use ordinances, such as zoning ordinances and subdivision regulations. GENERAL DEVELOPMENT OBJECTIVE - It is the objective of the Town to adopt policies and ordinances and take appropriate actions to promote the growth and development of the Town as a predominantly single-family residential community with limited supporting retail services and tourist oriented uses. The term "single-family residential" includes multi -family ownership units (for example, condominiums), provided such development is consistent with other Town policies and ordinances. TYPES OF DEVELOPMENT - It shall be the policy of the Town to permit single-family, commercial, and institutional land uses within the Town under the terms,of the zoning,ordinance and -in accord with the Natural Resource Policies. Preferred commercial uses are those necessary to provide limited retail and professional services to tourists and permanent residents. LOCATION OF DEVELOPMENT - The location of development shall be con- sistent with the Town Zoning Ordinance and the Natural Resource.Policies. Commercial, multi -family or single-family attached developments shall be planned and located so as not to interfere with surrounding residential development. TIMING AND DENSITY OF DEVELOPMENT - The timing of development shall be consistent with the Natural Resource Policies and the capacity of the Town to provide water and sewer services to additional projected development. Water, and sewer facilities should not be expanded to a capacity greater than that required to accommodate projected permanent or peak populations; that is, no facility expansions should be provided to induce or promote growth beyond that projected in the section on ESTIMATED DEMAND. The density of development shall be consistent with that allowable in the Town Zoning Ordinance. One particular issue with regard to density is the distinction between peak and permanent density, because each poses separate problems with different solu- tions. Peak density is density that occurs because of influx of visitor popula- tion, either overnight or day visitors. The peak density tends to greatly over- load the access system, i.e, roads and points of access to the beach and while adding some additional load on the water system, it is the permanent population. that has the greatest permanent impact on these facilities. The methods of implementation that follow these policies provide different techniques for solving each of these issues. CARRYING CAPACITY - One of the most important issues concerning Surf City is the relationship between the type, timing, location and amount of future growth and the capacity of the Town's natural systems to absorb this growth. Realistically, this translates into the capacity of the Town's soils to accept septic tank effluent without degrading surrounding estuarine waters or creating 29 a public nuisance or health hazard. The problem has been created in the past when septic tanks were poorly designed and installed and, most importantly, were located either in areas with high water tables which brought effluent to the sur- face during wet periods or in areas with rapid percolation rates which allowed effluent to reach ground waters. In either case, lateral movement, either across the surface of the ground or in the groundwater system, of the inadequately treated effluent reached surrounding estuarine waters, resulting in pollution and eventual _ closing of shellfishing areas. This effect was documented in a joint study con- ducted by the U.S. Environmental Protection Agency, the N.C. Department of Natural Resources and Community Development, and the N.C. Department of Human Resources which,focused on the h Old Settlers Beach area immediately north of Surf City's town limits. This study, and similar occurrences in other areas on the North Carolina coast led to the enactment of several rules and regulations for the loca- tion and installation of septic tanks. Generally, those rules require, for both single-family detached dwellings and for multiple family and commercial structures, that septic tank systems be located away from shellfishing waters and in areas with suitable percolation rates and low water tables. The enforcement of these rules is primarily in the N.C. Division of Environmental Management and county health departments. In addition, the CAMA AEC,requirements impose stricter requirements on portions of systems that may approach shellfishing waters. Sites not meeting these requirements must be modified, or the proposed development must be reduced in scope or abandoned. The Town of Surf City, and all development occurring therein, must conform to these regulations; thus, assuming the regulations and their enforcement are adequate, future development should not result in pollution of either groundwater or surrounding estuarine waters. The -issue in Surf City, as in other barrier island towns in North Carolina, is whether future development goals at projected densities will result in groundwater or estuarine pollution despite adherence to applicable on -site sewage disposal regulations. Alternative solutions to this possibility are as much, or more, a state responsibility as a local one --first, because of the complexity of the problem and highly technical information needed to determine optimum densities, and second, because the pollution of surrounding estuarine waters has more than local significance. The Town is equally concerned because of possible health hazards and also because of the potential loss in a valuable economic resource. However, at the present time, the state has yet to require or recommend optimum densities on a city-wide scale, 30 07 but has chosen to follow the current approach of requiring adequate sites under. the assumption that adequately designed sites will not collectively result in the pollution to be avoided. Without adequate information to indicate otherwise, the Town has no authority to restrict projected densities through zoning or other means as long as property owners are adequately complying with existing regulations. Further, given the low projected rate of future development, 38 acres of the 470 developable (8%) over the next 10 years, it is doubtful, in the absence of other information, that the problem will occur. Therefore, for the purpose of preventing future pollution of groundwater or surrounding estuarine water, the following carrying capacity policy is adopted. POLICY - It shall be the policy of the Town to insure that all future development adheres to all applicable local and state regulations governing the operation, location, and installation of on -site disposal systems. It shall further be the policy of the Town that any action by the Town that may result in an increase in density above that currently permitted under existing ordinances will consider the effects of such action on water quality; and should such effects be negative, the Town will take whatever action is required to mitigate those effects. BEACH ACCESS, PRESERVATION AND EROSION CONTROL - The basic issue is which of the alternative methods of beach preservation and erosion control will, consistent with state and local policies, provide the most economical, safe and environmentally acceptable protection. The two basic alternatives are struc- tural measures, such as bulkheads or groins and renourishment, and non-structural methods, such as vegetation maintenance and access control. The following policies are adopted for this issue. POLICY - Renourishment, supplemented by land use controls, access control and vegetation maintenance, is.the preferred alternative for erosion control. POLICY - Since the dune and berm is a resource used by persons through- out the region and state, the cost of its maintenance should be distributed among the user -beneficiaries in equal proportion to the benefit received. POLICY - The expenditure of public funds for dune and berm protection must be complemented by the provision of public access to the beach and shore. POLICY - To protect the dune system and its stabilizing vegetation by (1) routing the flow of pedestrian traffic to central points of access to the water, and (2) enforcing dune protection ordinances. 31 POLICY To implement the policies and recommendations of the Surf City Beach Access Plan. CULTURAL, HISTORICAL, AND ARCHEOLOGICAL RESOURCES - While there are no known or identified significant cultural, historical, or archeological resources within the Town, the Town recognizes that there may be significant resources that may be identified in the future in.the course of development. In an effort to recognize these potential resources and provide protection to the extent feasible, the following policy is adopted. POLICY - It shall. be the Town's policy to cooperate with state and federal agencies or other individuals and institutions in the protection and identification of significant existing or unidentified cultural, historical or archeological resources. HURRICANE AND EVACUATION POLICY - Recognizing the danger to lives and property from hurricanes and other severe storms, it shall be the policy of the. Town to maintain an evacuation plan for the Town at all times and to keep such plan updated to assure the safe and efficient evacuation of Town residents in the.event of storm threat. (A copy of the current plan may be found in the Appendices.) 32 4.0 LAND CLASSIFICATION 4.1 PURPOSE The land classification map is intended to serve as a graphic illustration of the Town's adopted policies. By delineating the classes on a map, policies (local, state and federal) can be designed for specific areas. However, land classification is not a regulatory mechanism, but is only a tool to help implement policies. It provides a framework to be used by local governments to identify future land uses and as a guide to where natural and cultural resources will be preserved. 4.2 LAND CLASSES The state guidelines define five land classes for local governments to use in further clarifying their policy statements. These are briefly summarized as follows: Developed - To provide for continued intensive development in cities -at or approaching densities of 500 dwellings per square mile and that provide major municipal services. Transition - To provide for future intensive development during the next 10 years on lands which are or can readily be served by major public services and which are free from severe development constraints. Community - To provide for clustered development in rural areas so as to facilitate the provision of public services. Rural - To provide for agriculture, forest management, and mineral extraction in low intensity areas. Conservation - To provide for long-term management of limited or irreplaceable areas, and generally should apply to important wildlife habitats, fragile resource areas, hazardous areas and public parks. There are two categories of land classification with significance for Surf City. These are the Developed and Conservation classes. Both of these require some modification in definition in order to be of use to the Town of Surf City. The Developed class, as explained above, is to provide for continued intensive development of areas currently developed at a density of 500 dwelling units per square mile, or at 1.28 dwelling units per acre; further, such areas should be 33 provided 'public water, sewer, fire and police protection and recreational facilities. Virtually all land within the Town falls within this classification, since the density ratio is_1.75 dwelling units per developable acre and all services except public sewer are provided. However, the guidelines do permit areas which exceed the minimum density but which lack public sewer to be divided into a separate class to indicate that although they have a developed character, they will need sewers in the future. The intent is to establish a modification of the Developed class that will recognize the constraints to development --both natural and community facility constraints --as well as the citizens' desire that the Town's future development proceed at current rates. The second category of land classifi- cation which requires recognition within the Town is the Conservation class. The purpose of this class is to provide for effective long-term management of signifi- cant limited or irreplaceable areas. Three such areas occur within the Town and will fall within one of the subclasses of Developed. These are the marshlands, the beaches, and the maritime forests. The degree to which development should be permitted in any of these areas is described in the following description of the land classes. DEVELOPED - The purpose of the DEVELOPED classification is to insure that future development within the Town occurs at rates and densities that are consistent with the Town's capacity.to provide necessary sewage disposal facilities and protect_ surrounding estuarine waters. Thus, it is intended that the rate and densities of development within this classification shall proceed at the current rate of development as established in Section 2.3.4, ESTIMATED DEMAND, and at the densities permitted under the Town Zoning Ordinance until sewage disposal facilities are available. All uses permitted under the Town Zoning Ordinance shall be permitted in this classification, in its appropriate district. This district is established for the purpose of promoting the ESTUARINE SYSTEM POLICIES, and the DEVELOPMENT POLICIES, all found under Section 3.0. It includes all areas in Town currently zoned for business or residential uses, but excluding marsh and wetland areas, beach area from mean high tide east, and the DEVELOPED - MARITIME FOREST. CONSERVATION - PUBLIC ACCESS - The purpose of this classification is to preserve the public rights of access to and along the beach and to protect the dunes and wildlife. Specifically, this classification is designed to implement the following 34 policies: BEACH PRESERVATION, BEACH ACCESS, RECREATIONAL FISHERIES, and covers the area between the toe of the dune and mean low water. CONSERVATION - MARSHLAND - This classification is established to include the coastal wetlands, estuarine waters, estuarine shorelines and public trust areas and spoil islands. It is specifically included to implement the ESTUARINE SYSTEM POLICIES and covers all the marshland areas. It includes all areas falling within the estuarine system or defined by the guidelines for Areas of Environmental Concern.

All uses currently permitted under the Town Zoning Ordinance will be allowed in areas with maritime forest, but only if con- sistent with this policy. RECREATIONAL FISHERIES It is the policy of the Town that existing and future piers constructed within the Town will be open to the public at reasonable fees. DEVELOPMENT POLICIES Surf City's Development Policies are established__. to provide a general guide to resolving basic land use issues concerning the type, timing, location, and density of growth. Citizen input becomes extremely important in formulating these issues and policies.. To obtain this input a citizen survey was conducted. The significant results of the survey were that 86 percent;of those responding want population to increase slowly or remain the same and 93 percent preferred single-family detached housing for future develop- ments with limited supporting retail and tourist -oriented uses. GENERAL DEVELOPMENT OBJECTIVE It is the objective of the Town to adopt policies and ordinances and take appropriate actions to promote the growth and development of the Town as a predominantly single-family residential com- muni.ty with limited supporting retail services and tourist oriented uses. TYPE OF DEVELOPMENT It shall be the policy of the Town to permit single- family, commercial and institutional land uses within the Town under the terms of the zoning ordinance and in accord with the Natural Resource Policies. Preferred commercial uses are those necessary to provide limited retail and y professional services to tourists and permanent residents. t LOCATION OF DEVELOPMENT The location of development shall be con- sistent with the Town Zoning Ordinance and the Natural Resource Policies. Commercial, multi -family or single-family attached developments shall be planned and located so as not to interfere with surrounding residential developments. TIMING AND DENSITY OF DEVELOPMENT The timing of development shall be consistent with the Natural Resource Policies and the capacity of the Town to provide water and sewer services to additional projected development. Water and sewer facilities should not be expanded to a capacity greater than J that required to accommodate projected permanent or peak populations. CARRYING CAPACITY It shall be the policy of the Town to insure that all future development adheres to all applicable local -and state regulations governing the operation, location, and installation of on -site disposal systems. It shall further be the policy of the Town that any action by the Town that may result in an increase in density above that currently permitted under existing ordinances will consider the effects of such action on water quality; and should such effects be negative, the Town will take whatever action is required to mitigate those effects. BEACH ACCESS, PRESERVATION AND EROSION CONTROL Renourishment, supplemented by land use controls, access control and vegetation maintenance, is the pre- ferred alternative for erosion control. Since the dune and berm is a resource used by persons throughout the region and state, the cost of its maintenance should be distributed among the user -beneficiaries in equal proportion to the benefit received. The expenditure of public funds for dune and berm protection must be complimented by the provision of public access to the beach and shore. { To protect the dune system and its stabilizing vegetation by (1) routing the flow of pedestrian traffic to central points of access to the water, and (2) enforcing dune protection ordinances. To implement the policies and recommendations of the Surf City Beach Access Plan. CULTURAL, HISTORICAL, AND ARCHEOLOGICAL RESOURCES -It shall.be the Town's policy to cooperate with state and federal agencies or other individuals and institutions in the protection and identification of significant existing or unidentified cultural, historical or archeological resources. HURRICANE AND EVACUATION POLICY Recognizing the danger to lives and _ property from hurricanes and other severe storms, it shall be the policy of the town to maintain an evacuation plan for the Town at all times and to keep such plan updated to assure the safe and efficient evacuation of Town residents in the event of storm threat. LAND CLASSIFICATION A system of land classification is intended to serve as a graphic illustration of the Town's policies; however, land classification should not be confused with the zoning map which is a regulatory mechanism.
