NEIL VESTER, MAYOR LO STEVENS HELL E SUTPHEN �DA URNEY OHV WOOD FIRST DRAFT JULY, M1 FINAL DRAFT JUKE • 19M D. Current Plans, Policies and Regulations Plans The only plan which Indian Beach has adopted is the 201 Wastewater Facility Plan. Indian Beach and western Carteret County are a part of the Swansboro 201 Facilities Plan. The selected plan recommends that wastewater treatment be provided for the Torun of Cape Carteret and West Bogue Banks as soon as possible because of existing water quality problems in these areas. However, because of the projected high local costs associated with the selected plan, it was determined that the plan could not be implemented at this time. Therefore, it was recommended that the project be re-examined at regular intervals to determine when or if a wastewater treatment system could be feasibly implemented in the area. The N. C. Division of Environmental Management concurs with the basic premise of the recommendations but must insist that alternative systems and methods of wastewater treatment be evaluated at intervals along with the implementation feasibility of any proposed project.' The plan was approved by the Town on January 12, 1978. Since construction costs are escalating so fast, it is doubtful the Towns would ever be able to afford their share (12.5% local, 75% Federal, 12.5% State) of the cost. In addition, EPA has all of North Carolina's barrier island communities' 201 facilities plans on hold until they complete the barrier island study. The study is designed to determine the impact federally funded subsidies (utilities, flood insurance) are having on these communities. * Letter dated AUgust 25, 1978, to Mr. A. B.

Areas of Environmental Concern (AECs) The AECs applicable to Indian Beach are described in detail in Appendix A. They are mapped on Map I. According to the "State Guidelines for Areas of Environmental Concern" (15 NCAC 7H), there are five distinct AECs in Indian Beach. These are: Estuarine Waters, Coastal Wetlands, Public Trust Areas, Estuarine Shorelines and Ocean Erodible Area. The importance of these areas and general discussion is found under I. E. 1. a. Hazard Areas on page 15 and I. E. 1. e. Fragile Areas on page 41. However, all hazard and fragile areas have not been designated as AECs. 10 t , r NC 5 _ 8 --�- _:_-- -- - _ �7. �( l O t I 1tt / It J Salter Path T15,9z TOWN OF INDIAN BEACH .CARTEREI COUNTY, NOR1H CAROLIUA ` V 000 00 lown of 1 _ rald Isle , -- ^- ^ ^ TONN LIHIT 6OCNCAF.Y SCALE 1• •1320, t EXISTING LAND USE MAP 1 _ ' 0 Residential, Single -Family t __O Residential, Multi -Family t_�.� Residential, Mobile Home Park ' - -- - Commercial Institutional • Town Hall Post Office + Baptist Children's Home Vacant/Maritime Forest The Maritime forest offers not only an aesthetic value but functions to retain rainfall in subsurface groundwater and stabilizes loose sandy soils. See discussion on page 51. Maritime forests con- tribute to the attractiveness of the barrier islands which is a fun- damental reason for its growth. Excessive mobile home development is a problem because mobile homes like conventional dwellings require the same amount of services from local government but unlike conventional dwellings do not provide proportionate tax revenue to pay for the services. Mobile homes are valued for tax purposes as personal property which diminishes in value each year. Consequently, mobile homes generate less tax revenue each year. Satellite annexation areas present problems of efficiency in municipal services unless the unincorporated "islands" are later in- cluded. Since Indian Beach offers few municipal services, ineffi- ciency is reduced. Only police must travel through the intervening area to get to the eastern satellite area. Identification of Areas Likely to Experience Changes in Predominant Land Use For Indian Beach, the areas likely to experience changes are those areas presently undeveloped with their dense vegetation cover of mari- time forest. Destruction of these areas will change drastically the character of the present settlement pattern, and it risks the very reasons why the area was settled initially. Also, a not so subtle change may result from an escalating land cost. As land becomes more expensive, the economic justification for single-family homes becomes more difficult. Consequently, more multi -storied, multi -family development will be proposed. This will Transportation as a land use is included in Urban and Built-up. Also, according to N.C. Department of Transportation, there are no facility improvements for Indian Beach scheduled in the seven year Transportation Plan. Future population growth is expected to create additional bi- cycle traffic, and this form of transportation needs to be considered. Significant Land Use Compatibility Problems Land use compatibility is the absence of adverse impact on two adjoining pieces of property. The classic example is a service station adjacent to a residential dwelling. Generally, similar uses make the best neighbors. Indian Beach's land use compatibility problems will increase in the future. As more people are attracted to the com- munity, the demand for services will increase. Businesses will want to locate as close to the demand as possible. The western portion of Indian Beach already has two focal points for trade and services. These are located at the Town Hall along N.C. 58 and at the fishing pier. As more residential development locates nearby, conflict will increase. Appropriate yard requirements and buffer space provision in the Zoning Ordinance should, if properly enforced, lessen the potential conflict. Problems and Implications From Unplanned Development Major problems and implications from unplanned development in Indian Beach include those associated with "finger" canals, maritime forest and vegetation removal, excessive mobile home development, and difficulty in providing services in satellite annexation areas. Finger canals are problems because they not only destroy valuable natural habitat and productive resources, they are expensive to maintain and almost always poorly designed. C. Existing Land Use The following chart illustrates approximate land use characteristics in Indian Beach. Land Use Acres q of Developed % of Total Urban and Built-up 134.6 100 37.0 Residential 121.0 89.9 33.0 Commercial 13.5 10.0 3.7 Governmental .1 .1 .3 Undeveloped 228.8 - 63.0 Total Land Area 363.4 - 100.0 As can readily be seen residential land use is the predominate land use. There are approximately 1,329 living spaces on 121 residential acres. Living spaces consist of mobile homes (815), camp spaces (489), and conventional homes (25). There are five mobile home parks and three camp parks. Commercial and governmental activities account for a nonimal amount of land use in Indian Beach. Undeveloped land includes land available for development both in the original corporate limits and in the satellite area. Without a doubt, the most significant aspect.of land use in Indian Beach is the 1,329 living spaces on only 121 acres which equals approximately 11 living units per acre. A very intensive land use without water and sewer . . . it has been estimated that at peak seasons, these 1,329 living units may contain as many as 2 to 4 persons per unit. This would yield anywhere from 2,658 to 5,316 persons on only 121 acres. 7 -t. Unfortunately, widespread media accounts of the report emphasized that, "North Carolina coast shows no widespread closures which can be attributed to septic tank failure." This came as good news to proponents of traditional septic tanks and developers who are not genuinely concerned about the environment. Yet, the report was very pointed if,one read beyond the headline. Areas such as Indian Beach must begin to deal with the problems rather than wait for some governmental agency to solve their own problems. It is no longer reasonable to wait for Federal and State agencies to fund wastewater treatment plants. M. Tourism is extremely important in the coastal area, particularly in Indian Beach because of the abundant natural resources that attract people to the coast. However, as can be seen in Indian Beach, the development necessary to serve vacation -tourist industry can often have.an adverse impact on the fishing industry. Dredging of finger canals, improper use of septic tanks, and marina construc- tion in coastal marshes have the potential for degrading the very attributes which originally attracted visitors to the coast. Inadequate wastewater systems and urban runoff have resulted in the closure of public waters to the harvest of clams and oysters, denying these resources to commercial and recreational fishermen alike. The Atlanta office of the U.S. Environmental Protection Agency (EPA) in January, 1981, released, "Preliminary Findings of the N. C. Barrier Islands EIS on the Closing of Shellfishing Waters Near Barrier Islands." The report stated that many coastal 201 wastewater treatment plans alleged that the contamination and resulting closing of shellfish waters was because of septic tank failures. EPA's "preliminary review of data on the status of shellfishing waters along the North Carolina coast shows no widespread closures which can be attributed to septic tank failures on the barrier islands. Water quality data from other monitoring stations along the coast appear to support these preliminary findings. Only in isolated areas such as finger -fill canals can septic tank failures be documented as the cause for the closing of shellfishing waters." The report goes on to identify shellfishing areas which have been closed potentially due to activities origina- ting on the barrier islands of North Carolina. One of those areas is Salter Path on Bogue Sound. •Area E-2 Bogue Sound (136 acres closed, 1.8% of 7200 acres available) Salter Path (136 acres): Man-made canals in this area have shown elevated coliform levels -- probably due to marine head effluent and septic tank leaching. 5 B. Present Conditions and Economy Indian Beach is a vacation -resort community. Year round (permanent) residents are either retired persons or are employed by vacation related businesses. The permanent population of 61 residents in 1980 is small in comparison to what is thought to be the summer peak population of 2,624. Because of its size, there is very little published data available for Indian Beach. The economy of Indian Beach is almost totally vacation oriented. There are five mobile home parks, three travel trailer parks and seventeen commercial establishments. The commercial establishments are designed to provide necessary services and entertainment for seasonal population of Indian Beach. The development of the vacation -tourist industry in Carteret County has been of great importance to Indian Beach. The growth of tourism during the late sixties and early seventies stimulated the economic desirability of Indian Beach. Indian Beach is presently an intergral part of the overall tourist industry in the County. Another important segment of the economic picture is,the fishing industry. Carteret County leads the state in total pounds of coastal fisheries caught and total commercial vessels licensed. Commercial fishing is big business in Coastal North Carolina with an estimated gross product of 325.6 million dollars in 1978. This figure includes all revenues generated by and spent on commercial and recreational fishing; vessel and boat construction, operation and maintenance; shore facilities including fish houses, processing facilities, piers, marinas, and seafood restaurant.. operations in Coastal North Carolina. 4 • The Town provides only police protection and some adminis- trative services to its residents. • The Town probably has more mobile homes per acre than any other beach community in the State. • The Town has not been designated as having a flood hazard when its neighboring communities and the County have been designated as having flood hazards. • The Town should investigate thoroughly the alternative wastewater treatment solutions presently available since the conventional wastewater treatment plant alternative is too costly. 3 I. DATA COLLECTION AND ANALYSIS A. Information Base This Land Use Plan for Indian Beach was prepared in accordance with CAMA Land Use Planning Guidelines (15 NCAC 7B). This plan utilizes inventory type planning work completed in 1976 in order that this major effort could be concentrated towards the development of policy statements for the Town. Essentially, the process of developing policy statements was as follows: 1) identify land use issues; 2) determine alternative solutions; 3) select most viable alternative; 4) draft policy statement reflecting selected alternative; 5) draft implementation strategy. The major conclusions of this plan are: • .Indian Beach is a very young community having been incorporated only since 1973. • Indian Beach is a vacation resort community and noted for its exceZZent fishing. • The community has five Areas of EnvironmentaZ Concern and two other fragiZe naturaZ systems, maritime forest and primary sand dunes. • The Town has experienced growth over the Zast 8 years and there is at Zeast one indication that growth may have adverseZy affected its environment. Introduction Indian Beach (western section) was incorporated by Legislative Act in 1973. The reason for incorporating was because of the unavaiZ- ability of land for commercial purposes in ac acent communities. Adjacent communities would not permit commercial uses or mobile home based on local police power ordinances (zoning) or deed restrictions. Most of the residents of the community of Salter Path being independent, were not interested in becoming a part of the new town. The boundary was drawn to exclude the community of Salter Path and extended 2,640 feet from mean high water into Bogue Sound and Atlantic Beach. In June 24, 1975, the N. C. General Assembly (Chapter 811, Session Laws, 1975) ratified an act to annex a certain non-contiguous area (eastern section) to the Town of Indian Beach as "satellite corporate limits." The boundary excluded Salter Path and utilized the high water mark as the boundary. It is thought that the satellite area was incorporated because of the approaching town limits from another community and the owners preferred the low taxes and less red tape of Indian Beach. It is unknown as to why the boundary used was not the same in regard to the waterfront as in the earlier incorporation. 1 TABLE OF CONTENTS LAND USE PLAN Page Introduction . . . . . . . . . . . . . . . . . . . . . . . . . 1 I.

It contains four districts: B-1 General Business, CM Civic and Municipal, R-15 General Residential and R-25 Single Family Residential. By today's standards and current practices, this Ordinance has some major deficiencies. Part of the problem is -format. In each district, there should be three sub- headings: Permitted Uses, Conditional or Special Uses and Dimensional Requirements. In this Ordinance, it is difficult to tell where Permitted Uses end and Conditional Uses -begin. This distinction is important because permitted uses are permitted by right, whereas, conditional uses are reviewed individually by the Board of Adjustment on a case by case basis. Mobile home parks are permitted uses in the Business District. While the majority of homes in Indian Beach are rented or leased, they are residential by every account. The State Supreme Court in North Carolina, in previous cases, has declared mobile homes to be single family residential structures. To classify them otherwise is to risk a declaration of the Ordinance as invalid. This Ordinance should acknowledge this fact and have a separate residential district for mobile homes. There is no difference between the R-15 and R-25 except that the former requires 15,000 square feet and the latter 25,000 square feet minimum lot size. Since both districts permit "single family dwellings" mobile homes on individual lots must be allowed since the Supreme Court has already declared them to be single family structures. Also, while 12 the lot sizes may be desirable, as a practical matter they are inappropriate. Almost all existing residential lots do not conform to these established dimensions. The section on non -conforming uses on page 9 is inadequate because of inconsistencies of use, dimensions, and structures. "Bona fide farms" on page 25 is inappropriate in a municipal zoning ordinance. Finally, motels are listed twice on pages 13 and 14. The Zoning Ordinance is being updated. Mobile Home and Travel Trailer Park Ordinance This Ordinance was adopted October 29, 1975. It requires a review of the preliminary plan and site specifications for mobile home and travel trailer parks. There are some serious deficiencies in this Ordinance dealing primarily with water and sewer requirements. The minimum mobile home park size is three acres. If public water and sewer are available, then the mobile home stall in a park requires 3,000 square feet. Since sewer is not available, this is not applicable. If neither public water or sewer is available, then the stall space is 15,000 square feet in a park. There is no provision for stall space where only public water is provided. There is a provision for mobile homes on individual lots if public water or sewer is available and requires 5,000 square feet per stall. Consequently, a.large void exists in the Ordinance since most parks have public water only. According to this Ordinance, these are unregulated. The Ordinance required 13 that all mobile homes and parks be in compliance by April 29, 1976. "Adjustment Procedures" in the ordinance are con- fusing since both the Board of Commissioners and Board of Adjustment are authorized to hear appeals. Subdivision Regulations are currently under consideration for adoption by the Town of Indian Beach. A listing of applicable State and Federal regulations appears in Appendix B. Policies The previously mentioned plans and regulations together with the Town Charter constitute the known policies under which Indian Beach operates. There could be unwritten policies which guide the Town's decision makers. 14 I. E. Constraints There are two major constraints to development on Indian Beach: (1) physical limitations owing to the land itself, and (2) the capacity of community facilities to support man's activities. These constraints are discussed below. I. E. 1. Physical Limitations to Development a. Hazard Areas - While there are no manmade hazard areas on Indian Beach, there are three natural hazards. These are: ocean hazard areas, estuarine shoreline areas, and flood hazards. In order to appreciate ocean hazard areas, it is necessary to discuss in detail the critical factors of it. ocean hazard areas* - This area consist of the beach and shore dynamics. Differences between beaches are apparent in their profile. The shape of this profile is controlled primarily by grain size, wave energy, and sediment input. The effect of grain size is relatively simple - the coarser the sediment, the steeper the beach. North Carolina beaches are rarely steeper than about 10%. The beach profile will vary in response to wave energy. The critical factor is the rate of delivery of wave energy to a beach. Wave steepness is measured by a ratio of wave's deepwater height to its length. As normal sea swells with low heights and relatively long distances between crests move onto shore, sand grains are picked up and moved landward a short distance. Drag against other sand grains and non -turbulent flow in the near bottom region prevent the grains from flowing Ecological Determinants of Coastal Area Management, Volume II, Val K ump and Johanna Smit Sea Grant Publication April, 1976. 15 back. The result is a net movement of sand on shore, -steepening the nearshore profile and shifting the berm seaward. The elevation of the berm is increased and widened as waves top it and transport sand over its crest. On the shore winds can in turn, carry this sand into the dune zone. As wave steepness and frequency increase as is common under winter storm conditions increased turbulence in the surf zone is encountered, keeping the sand in suspension. Material is eroded out of the berm and is transported offshore where it is deposited as an offshore sand bar or series of bars. The shore profile is flattened, causing waves to break further offshore dissipating their energy and slowing beach erosion. Thus, the beach responds to high wave energy by acting to relieve that energy. Manmade structures frequently interfere with this natural process by attempting to maintain a constant profile. The third factor, sediment input, is critical to the beach profile. High rates of sediment input usually allow a beach to build seaward. Beaches which experience a net loss of sediment, on the other hand, tend to erode and retreat. Whether a particular section of coastline is undergoing a net gain or loss of sediment depends upon a large number of interrelated factors that vary in time and importance, which are not accurately understood. However, the general trend along the North Carolina coast is erosion. Since grain size is essentially uniform along North Carolina barrier islands, the major factors controlling the beach profile are wave energy and sediment input. MI Furthermore, one geologic phenomenon which aggravates these factors is the rising sea level. Storm and wind generated surges coupled with rising sea level raise the water level, thereby exposing dune protection. Develop- ment near these areas is risky. It is curious to note that erosion is of little concern until man builds near the beach. Once the investments have been made, it then. becomes necessary to protect them. For regulatory purposes, Ocean Hazard areas have been delineated as areas above mean high water where excessive erosion has a high probability of occurring. See Appendix A. The basis for this AEC came from a study by the Center for Marine and Coastal Studies at North Carolina State University. It identified a probable recession line from the toe of the dune for one in twenty-five year storm return frequency at Emerald Isle as approximately 66 feet. A one hundred year frequency is estimated at approximately. 98 feet.* For regulatory purposes the Ocean Hazard for Indian Beach is a 60 foot area for the 30 year long term annual erosion rate plus an additional 50 foot area for the 100 year storm erosion rate. Together, this AEC is 110' from the stable vegetation. estuarine shoreline erodible areas - These areas are defined as the areas above ordinary high water where excessive erosion has a high probability of occurring. In the landward extent of this area, a reasonable 25 year recession line shall be determined using the best avail- able information. A Preliminary Study of Storm -Induced Beach Erosion :f Carolina C. E. Knowles, Jay Langfelder and et. al. October, 1973. 17 A method for determining estuarine shoreline erosion rates has been developed. A specific shoreline segment is directly dependent upon the following characteristics: average distance of open water in front of the shoreline; depth of water and slope of the bottom in the nearshore; height of bank; composition of bank sediments; vegetation - type and abundance; shape and regularity of shoreline; orientation of shoreline; and proximity to channel. Given these factors and a rated value, one can calculate an approximate erosion potential of any given shoreline.* This area has uniformly been determined under Coastal Area Management Act standards (15 NCAC 7H .0209) as 75 feet landward. This figure represents not a setback distance but a jurisdictional boundary on dry land. flood hazard areas - There are two types of flooding: "riverine" which is caused by precipitation and "coastal flooding", caused by wind driven water by the coincidence of storm and high tides. There is no coastal hazard area comparable to the riverine "floodway" which must be main- tained free of obstructions to convey flood flows. This is perhaps the most important difference between coastal and riverine-flood regulations. Coastal flood regulations are not designed to preserve flood flows. They are designed to preserve dunes and maintain the integrity of structures which are buffeted by high energy waves. Many communities already in the regular phase of the National Flood Insurance Program will be re-evaluated in order to consider wave heights which were not included in earlier base flood elevations. * 'Relative Estuarine Shoreline Potential in N. C." Michael P. O'Connor, Stanley R. Riggs, and Vincent J. Bellis East Carolina University, Greenville, N. C. April 14, 1978. Indian Beach is not participating in the National Flood Insurance Program nor has the community been identi- fied as having a flood hazard. No doubt, the identification is an oversight since both adjoining communities and the County have been identified and are in the regular phase. Once the Federal Emergency Management Agency (FEMA) identifies the flood hazard and the velocity zone, then CAMA's High Hazard Flood AEC will have been designated. Until then CAMA's High Hazard Flood AEC regulations are not in effect. However, since the V-zone exist in adjacent communities and in the county, it is an apparent oversight on the part of FEMA. Nevertheless, a flood hazard still exist and property owners should be forewarned. I..E. 1. b. Soil Limitations* The soils of an area determine the extent of present development and suitability for future growth. Probably all soils in Indian Beach could be modified to accommodate any selected use, but in many cases the cost (environmental, social and monetary) would be excessive. Since misuse can lead to severe environmental problems, the cost of improperly planned modification is often borne not only by the developer, but also by the public. Therefore, it is desirable to recognize the limitations of certain soils and to evaluate their potential or suitability for uses such as septic tanks, streets, piling foundation and others. For example, on -site disposal of septic tank effluent may create problems.,on the barrier islands. 'Utilizing Soil Surve , Outer Banks, N. C. Dept. of Agriculture Soil conservation Service an . Department of Natural Resources and Community Development and North Carolina State University June, 1977. 19 existing septic tank technology, many wet and/or impermeable soils in the area have severe limitations. In some dry, sandy soils --such as dune sand --the soil is too permeable to accommodate effluent; thus, pollution of groundwater and adjacent estuarine water is a problem. Even using current technology, it is difficult and/or expensive to overcome these limitations in a way that is not damaging to the environment. But when officials know these problems exist, requirements for development, such as minimum lot size or specifications for package wastewater treatment facilities, may be imposed. Soil Interpretation Interpretation sheets which follow the soil maps will not eliminate the need for on -site sampling, testing and study of specific sites for design and construction of engineering works and various uses. However, the information is useful for: (1) those who want a general idea of the soils, (2) those who want to compare the potential of different parts of the community, or (3) those who seek the location of areas suitable for specific types of land use. 20 is- F �•�Q d1 i` V 34 t E ,is advance copy of the Outer Banks Soil Survey has not been correlated and is subject to future finement.

A combination of all of these observations and measure- ments of soil features provides the basis for predicting their behavior and effects for a specific land use (see Tables 3, 4, and 5). Terms used in these tables are defined in the following paragraphs. Depth to the seasonal hi h water table (SHWT) - is the vertical distance from the surface of the soil to the highest level that groundwater (at atmospheric pressure) reaches in the soil in most years. Surface ponding is common in those soils that begin with zero inches in Table 3. It was not practical to provide measurement for water table depths that extend below 6 feet. Flooding - refers to water that stands or flows on the su— r ce as the result of ocean.or sound overflow or seep ponding. Terms for the frequency of flooding for a natural unprotected soil are as follows: None------ no reasonable possibility of flooding. Rare--- -- flooding unlikely but possible under abnormal conditions. Common---- flooding likely under normal conditions. Frequent-- more often than once in 2 years. This frequency for the marsh soils ranges from daily to monthly. Regular flooding results from lunar tide overwash. Irregular flooding is caused by overwash of sound and ocean waters as strong westerly or easterly winds from storms push these bodies of water over grounds above the mean high water mark. Frequency of flooding varies with fluctuating weather conditions.* Estimates of permeability - natural state and are based limited laboratory data. are for soil material in its on field observations and on 25 These areas usually revegetate naturally with smooth cordgrass, largeleaf pennywort, and other grasses and sedges, if landowners have not attempted to establish lawns or other kinds of vegetation. 18) Carteret soils high - This mapping unit consists of irregu ar y flooded -salt marshes. They have been formed in sandy marine sediments, and the soils have variable amounts of shells. The largest areas of this soil start near Bogue Inlet and extend north to the Roanoke Sound. Most areas lie about 1 to 14 feet above sea level. They flood at least monthly and in some areas may flood weekly with storm or wind tides. Salt contents that range from about 15 to 30 parts per thousand were measured in typical areas of this unit. The surface layer commonly contains a thick root mat. Where the soil material is exposed to the air, it gives off a sulfur odor. 5" to 0; black live and dead roots 0 to 5"; dark gray loamy sand 5 to 24"; gray sand 24 to 55"; dark gray sand Organic Material Soil Horizons: A Soil profile drawing of Carteret soils, high. The dominant vegetation is black needlerush; but some areas have scattered patches of saltmeadow cordgrass, bulrush, sea oxeye, marshelder, saltgrass, eastern baccharis, and three -square. These areas are significant in the life cycles of some forms of marine life. They have a low support capacity for structures. 35 0 to 3"; very dark grayish brown fine sand 3 to 8"; dark grayish brown fine sand 8 to 13"; light brownish gray sand 13 to 17"; dark gray sand 17 to 60"; gray sand Soil Horizons: A 'C f� Soil profile drawing of Duckston fine sand. Water moves readily through this sandy soil. Depth to the seasonal high water table is variable. During wet seasons, water is at or near the surface, as compared to depths of 2 to 5 feet when rainfall is limited. A few of the lower -lying areas may have water standing on the surface after high -intensity rains. Areas of this soil that are behind breaches in the foredunes are flooded by salt water during storms. In addition, areas adjacent to the sound are occasionally flooded by high wind tides. - 17) Madeland - This mapping unit is adjacent to the water . on the soup side of the islands. The soil material has been pumped or dredged during the construction of canals and has been deposited between the canals to be used as building sites. Essentially, all of the material has been deposited over marsh. The average thickness of the soil material ranges from 3 to 6 feet. The water table fluctuates with changes in tide level; however, most areas have a water table 2 to 4 feet below the surface during high tide. The material is mainly sandy, but some areas contain up to 10 percent shells. Water moves through the material readily and most areas are droughty. They generally have poor filtering capacity for septic tank effluent, and the potential hazard of groundwater pollution is high. These areas are commonly used for homesites because of the access to the water. Landscaping of these areas usually requires technical assistance to help solve the associated problems. 34 y .0 to 411; dark grayish brown loamy sand 4 to 10"; dark gray loamy sand 10 to 34"; gray loamy sand :r: -34._to...8011; greenish gray sand Soil Horizons: A C Soil profile drawing of Carteret soils, low. Salt contents that range from about 20 to 35 parts per thousand were measured in typical areas of this soil. Sulfur odor was also evident when the soil material was exposed to the air. Laboratory data of several samples showed a sulfur content of 0.01 percent or less in these sandy marsh soils. 12) Duckston fine sand - This mapping unit consists.of poorly draine-Usoils. hey occupy the nearly level to slightly depressional flats that extend inland from the frontal dunes. Also, they are in the small, irregularly - shaped depressions between the Corolla and Newhan soils. The soils are sandy throughout. They contain a high percent of coarse sand, few to many fragments of shells, and a buried surface layer within 80 inches of the surface. Native vegetation is dependent on proximity to the ocean. Areas affected by salt spray are dominantly vegetated by dense stands of saltmeadow cordgrass and scattered waxmyrtle. As the distance from the ocean spray increases, less salt -tolerant grasses and sedges occur along with greenbrier, eastern baccharis, black willow, redbay, three -square, scattered cattails, blueberry, wild olive, and Virginia creeper. 33 Soil Units 3) Beach-Foredune Association - This mapping unit is mainly on the ocean side of the an s" and islands; however, a few areas of beach are adjacent to the inlets. It is long and narrow and includes both the beach and the "frontal dune." A major portion of the foredune is covered with vegetation, consisting mainly of American beachgrass, sea -oats, coastal panicgrass, and bitter panicum. The beaches are low-lying and are flooded daily by tidal action. The sand ranges from fine to very coarse in size but is chiefly fine. Shell fragment content ranges widely. The back portion of the beach (berm) is slightly higher and is less affected by normal tidal action. It also contains shell fragments and varies in sand sizes. The berm portion is quite variable and, in places, is practically nonexistent. The soft, fluffy, loose sand is susceptible to severe blowing, particularly in the broader areas. In some areas, this blow- ing supplies fine sand to the adjacent dunes. The beach is invariably void of vegetation. The foredune portion consists of a dune just landward and parallel to the beach. Its height ranges from about 3 to 20 feet. In some places it is absent or has been breached by tidal or wind action. Since the frontal dune serves as protection for the more landward areas during storm attack, some foreduners have been artifically constructed.to function as such barriers. Tidal flooding of the beaches is a severe limitation to all uses .other than beach -related recreational activity. The foredune is subject to excessive erosion by wind and wave action unless vegetation can be established and maintained. In this survey area, a line was not drawn between the beach and foredune because this area is changing constantly. 6) Carteret soils low - This mapping consists of very poor y ra ne , sandy, marsh soils. They occur from the South Carolina line to the Roanoke Sound but are more extensive in the southern part of the survey area. These Carteret soils have formed on the sound side of the barrier islands. They are flooded daily by ocean tides and are vegetated mainly with pure stands of smooth cordgrass. 32 The climate of the barrier islands is modified by its proximity to the Atlantic Ocean. Temperatures are not as cold in winter and not as hot in summer as they are on the mainland. Winters are generally mild, and the freeze -free period is about 290 days. Rainfall is well -distributed throughout the year, with summer rainfall the greatest. The fall of the year is usually the driest period. The only weather station on the barrier islands is at Cape Hatteras; but data from Norfolk, Virginia, and Wilmington, North Carolina, may be used for general comparison of north to south differences. Tropical hurricanes are an important influence on the islands and come close enough to effect them on an average of about twice a year. This type of storm strikes the state with enough force to do damage to property on the average of about once in ten years. The climate of North Carolina's coastal barrier islands probably does not vary enough from north to south to produce different soils. The vegetation differences from Currituck Banks to Smith Island do, however, provide an indication of climate differences. Sea -oats reaches its extreme northern limit on Currituck Banks where American beachgrass reaches its southern limit. Northern bayberry ranges only as far south as Oregon Inlet, while on the extreme southern coast, Smith Island has some semi -tropical species such as cabbage palmetto. In summary, the islands and their soils are not static but are subject to frequent changes, as a complex combination of environmental factors produce a dynamic landscape subject to rapid changes.

The soil forming factors are parent material, climate, organisms, relief, and time. The influence of these factors is interde- pendent but by no means equal. In the barrier islands soil survey area, these factors influence soil formation in varying degrees. Parent material, time, relief, and organisms (plants) are the factors which account for most of the soil differences and are interrelated in a complex manner. The climate affects soil development, but it is relatively similar over the survey area. The parent material of most of the soils in the area is sand of marine origin. Several hypotheses regarding the formation of the barrier islands have been proposed, and recent evidence indicates that land features may be only several thousand years old. The relief of the sand deposits and the length of time they remain in place are effected greatly by wind and water. Examples are dunes which are frequently shifted by wind and sand which is transported by water. These processes occur during storms when overwash may occur and during the opening and closing of inlets. Numerous buried surface horizons provide evidence of these rapid changes in land form. This lack of stability limits the time available for soil development. The relief effects moisture available for plant growth since elevation changes of a few inches influence the vegetative types which occur in both the marsh and the dune areas; and the plants, in turn, influence soil development. Plants are the most obvious organisms which effect soil formation; and their distribution on the barrier islands is affected by environmental factors such as shifting sand, salt spray, and relief. On the islands, stabilization by plants is necessary for soil development to occur. In the foredune area, only salt tolerant grasses such as sea -oats and American beachgrass can survive. On the landward side of the dunes, shrubs such as live oak, yaupon holly, and waxmyrtle are able to grow, usually exhibiting a characteristic sheared appearance due to windborne salt spray. Where the barrier islands are sufficiently wide, forests develop that are similar in vegetative species and appearance to those on the mainland. Thus, position of vegetation on the landscape has an important influence on soil formation. A dune field close to the ocean supports only grass vegetation while the same parent material farther from the ocean eventually supports trees. Different soils develop in the two locations due to the influence of the vegetation and the longer period available for soil development at the stabilized wooded site. 99 TABLE 3.

The soils are droughty, and the natural fertility is low. They have a thin surface layer which contains a low amount of organic matter and plant fibers. The soils have formed in stratified sandy deposits that range from fine to course; sand with varying amounts of shells. 0 to 2"; grayish brown fine sand 2 to 50"; light gray fine sand 50 to 12" ; light gray sand Soil Horizons: A C Soil profile drawing of Newhan fine sand. These soils usually occur in long ridges on dunes that parallel the ocean. Elevations range from 5 to 60 feet or more. Slopes vary from nearly level and smooth to steep and complex. Typically, each mapping unit has more than 50 percent plant cover. The principal plants include American beachgrass, seashore elder, searocket, sea -oats, smooth cordgrass, bitter panicum, bluestem, and other species adapted to the effects of salt spray, blowing sand, and droughty soil conditions. The percolation of water is very rapid in the Newhan soils. Areas of this soil that are void of vegetation are subject to severe blowing. In order to stabilize these soils and prevent bare spots from blowing, a vegetative cover must be established and maintained. American beachgrass and bitter panicgrass are suitable for this purpose. After grasses 36 have been established, shrubs can be planted in areas protected from salt spray. These species include waxmyrtle, northern bayberry, yaupon holly, and flameleaf sumac. These shrubs will provide a more permanent cover than the grasses, as well as an environment within which other native plants can become established. 22) Newhan-Corolla complex - This mapping unit consists of two soils, the dominant Newhan soils and the minor Corolla soils. They occur in such an intricate pattern on the landscape that it was not feasible to separate them at the scale used in mapping. In many places, this unit. actually occupies the transitional zone between the higher - lying dunes to the east and the broad flats to the west. It consists of low dunes with short, complex slopes and the nearly level, intervening basins that separate the dunes. The Newhan soils are on the low dunes. They are well -drained to excessively drained, droughty, and have low natural fertility. They have a thin surface layer that is low in organic matter content and plant fibers. The soils have formed in stratified sandy deposits that contain mostly coarse sand and varying amounts of shell fragments. The water table is more than 7 feet below the surface. Vegeta- tion common to the Newhan soils includes American beachgrass, seacoast bluestem, coastal panicgrass, bitter panicum, largeleaf pennywort, and ragweed. The Corolla soils occupy the irregularly -shaped basins. They are moderately well -drained and sandy throughout and generally contain an older buried surface layer within 80 inches of the surface. The sandy material contains a high percent of coarse sand, along with varying amounts of shells or fragments of shells. During the winter, the Corolla soils typically have water within 15 to 20 inches of their surface. However, small areas where the seasonal high water table is at or near the surface are included in the mapping units. The common vegeta- tion includes saltmeadow cordgrass, live oak, waxmyrtle, seashore elder, searocket, eveningprimrose, and largeleaf pennywort. The soils that lack sufficient vegetative cover are subject to soil blowing. To stablilize and prevent the soils from blowing, a vegetative cover must be established and maintained. American beachgrass and bitter panicum 37 are suitable for this purpose. After stabilization has been accomplished, shrubs can be planted in areas protected from salt spray. Suitable species are waxmyrtle, northern bayberry, yaupon holly, ragweed, flameleaf sumac, and seacoast bluestem. The shrubs will provide not only a more permanent cover than the grass.but also an environment within which other native plants can become established. 24) Newhan-Urban land complex - This mapping unit consists of areas of Ne-Ran soils and urban land that are too intricately mixed to be separated at the scale used in mapping. They occupy developed areas such as Nags Head. Newhan soils occupy more than half of the mapping unit. Their soil properties and interpretations are similar to those given for Newhan fine sand, unit 21. The urban land portion of this mapping unit includes the area covered with buildings, driveways, streets, and parking lots. In these areas, the surface is covered with impervious material. Slope is generally modified to fit the site needs. The extent of site modification is variable. Many areas have had little disturbance while other areas have been cut, filled, or both. The urban land part of this mapping unit ranges from 15 to 50 percent, but typically covers about 20 percent of the land area. 38 I. E. 1. c. Water Supply Appraisal* Since no fresh surface water bodies exist in or near Indian Beach, the Town is not located in a designated public water supply watershed. Practically speaking, groundwater is the only available source of water supply that can be developed to meet the Town's present and future demand for water. While there is a paucity of specific well data from Indian Beach, the generalized data suggests that usuable water can be obtained from wells exposed either to the Surficial Aquifer or the Limestone Aquifer. The Surficial Aquifer, commonly known as the water table aquifer, exists from a few feet below land surface to a probable depth of sixty feet. The geologic formations that comprise the aquifer framework consists of sand and semi -consolidated sandy shell. The quality of water derived from this aquifer is fair to good: iron is the most objectionable constituent in the water. Wells exposed to.this aquifer are capable of yielding up to 100 gallons per minute of water. However, overpumping of this aquifer should be avoided to prevent saltwater intrusion problems. The Surficial Aquifer is replenished by rainfall that falls on the sandy land surface. Therefore, a considerable portion of Indian Beach is located over a recharge area. Since waste- water effluent from septic tanks is also a source of recharge to the Surficial Aquifer, every precaution must be exercised in the location and construction of a water supply well in this aquifer. * Memorandum from Richard S. Shiver, Wilmington Regional Hydrologist, N. C. Department of Natural Resources and Community Development, Wilmington, N. C. April 13, 1981. 39 1.. t Underneath the water table aquifer, and separated from it by a mud layer, the Limestone Aquifer is an artesian aquifer that extends from 200 feet to 400 feet below land surface. At depths below 400 feet, the Limestone Aquifer still exists but the water is believed to be brackish. The potable portion of this aquifer contains enormous quantities of water stored in the pores and cracks of a semi -consolidated to consolidated shell limestone. The quality of water from the Limestone Aquifer is good to very good: iron is an occasional nuisance -causing constituent, however. Wells exposed to this limestone are capable of yielding 300 gallons per minute of water. Saltwater intrusion does not now threaten to deteriorate the good quality of water from this aquifer. By basing water usuage on 1980 population estimates, Indian Beach's water demand varies from 4,000 to 169,000 gallons per day of water. Maximum usage, of course, occurs during the peak tourist season. Presently, there is no data to substantiate any quality - or quantity - related problems with the Town's groundwater resources. However, with increasing growth, water supply problems may occur - especially during the Town's peak tourist season. Therefore, as an element of prudent planning, the Town officials are . encouraged to monitor and assess their water supply needs in terms of viable options that would assure the Town of a continual supply of usuable water. 40 I. E. 1. d. Excessive Slope Indian Beach does not have any areas where the predominate slope exceeds 12 percent. However, there are some isolated spots where sand dunes may approach this degree of steepnees. These areas are subject to migration where they are not sta- bilized due to wind erosion. I. E. 1. e. Fragile Areas An understanding of the biological components of fragile areas is the key to understanding barrier islands and areas of environmental concern. This information is included be- cause of the educational value the Land Use Plan serves in Indian Beach. The following is a detailed discussion of the biological components of barrier islands. Some of the components are also a part of various areas of environmental concern (AEC). For example, the estuarine system, the mud and sand flats, the oyster rocks and the salt marshes are biological compo- nents of the Coastal Wetlands AEC and the Estuarine Waters AEC. The biological importance of these areas can not be over- stated. These biological components are the reasons for these areas being fragile. The maritime forest is a fragile area but not an AEC. 41 The estuaries represent some four thousand miles of shoreline --an area unsurpassed in terms of development potential which requires careful planning. And finally, the estuaries are interconnected with the intracoastal waterway and an important thoroughfare, commercially and recreationally. The estuarine system is further divided into the brackish water and mid -salinity systems. Brackish water systems are located at the point of contact between freshwater and saltwater and generally have 8 parts per thousand or less salinity. The mid -salinity systems which include Bogue Sound have anywhere from 8 to 30 parts per thousand salinity. Differences in -size, amount of freshwater input, and access to the sea produce varying acreages of mid -salinity waters. Mid -salinity systems, like all estuaries, are the result of interactions between tidal currents, river flow, temperature, wind, rainfall, sunlight and the physical shape of the estuary itself.* Most of these exhibit a great deal of variation daily as well as seasonally. For example, the combination of river flow and tidal currents produce a two layered system of circulation within most estuaries, a system vital in transporting those organisms which utilize the estuary as a nursery area. Denser salt water, energized by the tides, moves upstream underneath the lighter river water flowing downstream, creating a net downstream movement at the surface and a net upstream move- ment along the bottom. This circulation pattern transports larval and juvenile organisms from both offshore and upriver, carrying them into the nutrient -rich marshes and tributaries. Ecological Determinants of Coastal Area Management, Volume II Wilson Laney. 42 When they leave the estuary as elder juveniles or sub -adults, they ride the high -velocity surface currents out into the ocean. Consequently, it should be noted that if one component of such a complex relationship is damaged or destroyed, the entire relationship could be altered or affected in ways which could be irreversible. Data for 1974-78 clearly demonstrates that North Carolina commercial fisheries are based almost entirely on estuarine dependent species.* Secondary benefits are revenues derived from operation and maintenance of the gear required for the commercial and sport fisheries, marinas, boat yards and other repair and supply facilities and processing plants. Furthermore, no one can accurately assess the value associated. with recreational purposes from using the mid -salinity system. One indication of how much they are enjoyed is the increase in visitors and permanent residents each year. A sample of the consequences of man's activities and impact upon the environment is illustrated in the chart on the following pages. The single -most important point to remember is that the estuary has many components and any alteration to one is likely to upset another. *North Carolina's Coastal Fishing Industry, Michael W.

Mud flats along a particular shore are dependent upon bottom topography and speed of water currents carrying suspended sediments. Just how shallow the bottom has to be is determined by the tidal difference for a particular body of water. Deeper bottom areas can become flats in sounds with larger tidal ranges than those with smaller ones. An important food source for animals living in mud flats is decaying plant and animal matter called detritus. Animals composing mud and sand flats communities can be divided into two major groups --temporary and permanent members. Permanent members are the snails, worms and clams who spend their whole adult lives on the flats. Temporary members are bacteria, algae and micro organisms. The most commonly known animals living in tidal flats are claims and crustaceous. However, during high tide the mud and sand flats become feeding grounds for fish and crabs. During low tide predators of the flats include raccoons, rats, otters and especially birds. In addition to the direct value of clams, fish and wildlife, the mud flats have indirect value due to trapping and cycling nutrients. This helps supply necessary amounts of nitrogen, phosphorus and other elements to the overlying waters to be utilized by organisms vital to estuarine food chains. The most serious impact of man's activities is that of dredging coastal intertidal areas and expanding permanent shoreline through bulkheading. Other activities such as runoff reduce oxygen levels which suffocates the bottom organisms. * Ecological Determinants of Coastal Area Management, Volume II o n B. Williams. 47 3) oyster rocks* - While not a true geographic hazard area, oysters are reef organisms which grow on their own shells. Under suitable conditions of temperature, salinity and water flow, a single oyster will attach itself to any solid material such as a rock, stick or underwater structure. Other oysters then continue to attach to one another until the cluster gradually increases forming a reef, bar or oyster bed. Large reefs provide the basis for multi -million dollar farming operations, as those living singly and widely dispersed do not offer much commercial value. Oysters depend on moving water to provide oxygen and food as well as to carry away the waste products of their metabolism. It has been calculated that an average oyster will filter approximately 15 liters of water per hour, and a volume of water at least equal to this amount must be provided to each living oyster on the reef in order that the reef be maintained. Ideal current conditions are a steady non -turbulent flow of water over the oyster bed. Sedimentation, parasites, predators, and man's activities are the threats to oysters. Man's impact can be divided into three basic categories: overfishing, pollution and dredging. Overfishing continues today and will in the future as long as we ignore the principle, "in order for any natural resource to be maintained, the amount of it which is harvested must not exceed the amount regenerated annually." Pollutants which are lethal and those less toxic affect both adults, larvae and juveniles. Because oysters are filter feeders, they collect pollutants in concentrations many hundreds of times greater than the levels found in the surrounding environment. * Ecological Determinants of Coastal Area Management, Volume II Ronald Fiore. 48 The discharge of untreated domestic waste has a threefold effect upon oyster reefs. It covers the bottom with sludge that smothers the oyster bed, affects functions due to decreased oxygen in the water and greatly increases the water's bacterial and viral content. This type of contamina- tion eliminates the grounds as a commercial fishery because it creates a health hazard to humans using oysters as a food source. However, the growth and development of the oysters themselves may not be materially affected. Other forms of pollution such as thermal, toxic, radio- active and oil all have adverse effects. Dredging for the purpose of digging a channel or filling in a marshland may obliterate an oyster population by depositing sand and silt. However, it has been determined that controlled dredging operations taking place at least 400 yards from live oyster reefs are possible without causing too much harm. Annual oyster landings remained upwards of 1 million pounds until 1962, but have not reached that figure since in North Carolina. 4) saZt marshes* - Salt marshes are fairly flat beds of salt -resistant vegetation that are alternately flooded and drained by salt or brackish water. The frequency, duration and salinity of the water that floods a marsh determine the plant species and the characteristics of that marsh. In North Carolina, salt marshes are of two kinds: regularly and irregularly flooded marshes. Vegetation dominating each marsh is different. Generally, from the Cape lookout area south, the majority of the salt marshes are regularly flooded ological Deteminants`of,Coastal'Area,Management, Volume II ren Bolster. 49 S artina marshes. The unique productivity of the estuarine system is supported by detritus. Several small species of fish live in the marsh and are preyed upon by larger fish of commercial importance. The marsh serves as valuable habitat for a variety of animals. These include mice, rats, muskrat, mink, otter. These animals feed on the roots, rhizomes, stems and seeds of marshes. In its function as a buffer zone between high ground and the estuary, the marsh is believed to act in many cases as a moderating factor on the impacts of the two environments on each other. Thus, the marsh serves to protect uplands from storm and flood damage by the estuarine water by slowing the velocity of the water and therefore, dissipating wave energy. Because the marsh slows the velocity of water movement, it also serves as a "sediment tray" for the estuary. As water is slowed by passing over the marsh, particles fall out of the water and are deposited on the marsh. In this way, the marsh cleanses the water by decreasing its turbidity or particulate load. Consequently, the marshes act as a filter and stabilizer of erosion forces. From the above, we see that marshes have primary value (value harvested directly) since it serves as habitat for commercially important species such as muskrat, otter, mink and oyster. Secondary value (value harvested indirectly) are of greatest value to man. The marsh is a source of nutrients and detrital material. The marsh serves as a nursery ground for commercially valuable species such as shrimp, mullet, menhaden and striped bass. It also serves as a habitat for small fish which are a source of food for 01 larger forms. It is believed that the marsh acts in a manner similar to a tertiary sewage treatment plant because of its efficient nutrient recycling. The expense of building tertiary treatment plants to function similarly would be enormously expensive. Marshes act as "sediment traps" by slowing the water flowing over them and protect uplands from storm damage. The tertiary value of marsh is difficult to evaluate in a monetary scheme in that it contributes to the aesthetic, recreational, scientific and educational use. 5) maritime forest* — A significant portion of North Carolina's tourist income is derived from providing a pleasant beach experience. Poets, artists, and persons from all walks of life find inspiration in the varied landscapes. The maritime forest soils are relic ocean sediments. Most of the mineral elements required for forest nutrition are derived from salt spray. Even the sculptured appearance is in direct response to salt blown in from the sea. Thus, the maritime forest contributes to the visitors' enjoyment of the seashore. Other functions are less obvious, but in fact may be vital in holding the barrier islands in equilibrium with erosion forces. These functions are: retention of rainfall as subsurface groundwater, stabilization of loose sandy soils in the face of frequent strong winds and conservation of scarce nutrients (potassium, calcium) from salt spray and rain. Dominant tree species in relatively undisturbed areas are usually live oak, laurel oak, or yaupon. Associates usually include wax myrtle, red cedar, red bay and American holly. The maritime forest originated by adaption * Ecological Determinants of*Coastal-Area-Management, Volume II Vincent Bellis and EdwardProffitt. 51 of salt -tolerant components of the Coastal Evergreen Forest. Salt spray effects are most severe along the seaward edge of the forest. Here the forest canopy is kept compact and low because upward dominance of the branches is destroyed whenever terminal buds are destroyed. This stimulates lateral buds. Such tree development provides an effective wind barrier. Most of the mineral inputs are derived from salt spray. Unlike the adjacent salt marshes, the maritime forest does not appear to be highly productive due to salt stress and low mineral base. Along Bogue Banks, it has been common practice to establish trailer parks by pushing the toe of parallel dune ridges into the intervening swale ponds. Destruction of the forest canopy during this process results in increased evaporative water loss from the soil, while subsequent removal of the tree deposits by lot owners further increases evaporation. Filling of the swale ponds results in loss of water -holding capacity. Human population demands upon the freshwater supply increases even as man's activities function to reduce water trapping and holding capacity of the natural system. The impact of human disturbance is likely to be cumulative and may be largely reversible. 6) other fragiZe areas - Another fragile area involves cultural resources. These are more site specific when located. However, in the case of Indian Beach only two archaeological sites are documented. Recent correspondence with the N. C. Division of Archives and History revealed the following. "According to our initial review, sites 31CR29 and 32 are located in the planning area. It was our assessment that other sites are likely to occur, especially in areas indicated as "transition" on the Indian Beach map provided with the plan. Both recorded sites are now mostly or completely destroyed. 52 Site 31CR29 was located at the northwesternmost extremity of Salter Path (adjacent to Bogue Sound) on a twelve foot brush -covered dune. The site, consisting of several burials, was discovered during removal of the dune by the landowner. Eventually, about 90% of the dune was removed to make way for a moorage channel. A small portion (unspecified on the site form) of the dune lies on Salter Path community property. Because of its probable total destruction, site 31CR29 is of limited research importance. Yet, it does serve to draw attention to the fact that other such sites may exist undisturbed in the area. Located in the general vicinity, but.about 0.4 mile from the new moorage channel, site 31CR32 is unfortunately of similar informational potential. Its finding is from collectors' word-of-mouth accounts about artifacts discovered in the area. A site check confirmed the location since flakes and portions of pipes were found. The area is a large one subject to "obliteration due to loose blowing sand. While both 31CR29 and 32 had the.potential to yield archaeological data pertinent to the early settlement of the area, both are now of limited informational importance due to their destruction by both artificial and natural means. The sites are, however, important for the precedent they set for the probable location of other such sites in the area."* Consequently, these sites serve as an indication of the potential for similar resource sites. I. E. 1. f. Areas with Resource Potential Indian Beach does not have any known areas of resource potential as described in 15 NCAC 7B .0202 (c) (3). * Letter dated January 11, 1982, from Mr. John J. Little, Deputy, State Historic Preservation Officer. 53 I. E. 2. Capacity of Community Facilities The Town of Indian Beach does not own or operate either a water or sewer system. However, the western area (adjacent to Emerald Isle) is served by the Bogue Banks Water and Sewer Corporation. This is a private non-profit corporation which provides water to its . customers in Emerald Isle, Indian Beach and Salter Path. Service to Indian Beach is provided by a 6 and 8 inch waterline which lies under N.C. 58. The corporation does not construct extensions. That is the responsibility of the property owner. Recently, an extension was added.to serve the Colony by the Sea Condominiums in the eastern area of Indian Beach. Since the water system is not owned or operated by the Town of Indian Beach and it serves a much larger area than Indian Beach's corporate limits, the capacity is not a responsibility of the Town of Indian Beach. Nevertheless, it should be an important planning consideration for the Town. 54 I. F. Estimated Demand 1. Population Estimate Due to the small size and lack of historical data for Indian Beach, forecasting population is at best guess work. The following does not account for any future economic change as brought about by location of a major industrial employer nearby or a national recession. Historic Population Percent Change Actual Decrease 1960 1970 1980 1970 - 80 1970 - 80 Indian Beach - 60* 54 -10 - Carteret County 30,940 31,603 40,794 29 9,191 In- crease Source: U.S. Census of Population * 1973 estimate at incorporation Indian Beach Population ProJ ections 1990 Permanent Seasonal 500 2,500 Source: 1976 Indian Beach Land Use Plan (unadopted); combination arithmetic and percentage adjustment 55 I. F. 2. Future Land Needs Indian Beach has over 60 percent of its total land area undeveloped (228.8 acres). There appears to be sufficient land available to accommodate future land needs but not at the same intensity as present development levels. It is doubtful that the natural carrying capacity of the barrier island could absorb the waste generated if the remaining land is developed at the same intensity as the existing development of 11 living units per acre without the necessary facilities. Future de- velopment is not as intensive as existing residential land use and if land use control measures are implemented which prohibit development at the present density, adequate land for develop- ment will be available. Obviously, using more land area per residential unit may not permit that residential use (mobile home) to be economically feasible. In fact, tighter controls may cause the land value to increase and effectively eliminate mobile homes as an alternative residential land use. By the same token, the community cannot continue its present course of intensive residential land use without requiring the necessary water, sewer and other municipal services. The provision of basic municipal services alone will not eliminate all forms of environmental degradation. It is now well recog- nized that "non -point" discharges such as urban runoff and agriculture contribute greatly to the total pollution problem. -56 I. F. 3. Community Facilities Demand As previously stated, water is available to Indian Beach citizens from Bogue Banks Water and Sewer Corporation but the town has no municipal sewer service... A public/community sewer system is imperative if the community is going to continue to grow and attract vacationers and fishermen from across the State and Nation. This facility could be provided more economically with a cooperative agreement with neighboring communities also needing sewer service. Sewer systems are very expensive and would probably not be cost- effective for Indian Beach at this time. However, the risk to health is too important not to be doing anything about it. The Town could begin by requiring proven alternative septic tank systems (i.e., low pressure mound and package plants with subsurface discharge for larger projects) and monitoring closely their installation and operation. The county health department has jurisdiction over small waste water disposal systems. However, the county's concern is from a broader perspective and it must deal with the mainland as well. Indian Beach must ultimately be responsible for its own health, safety and welfare. 57 II. POLICY STATEMENTS In order to avoid any misunderstanding, the frequently used terms of goal, objective and policy are defined as follows: GoaZ--a desired future condition; Objective --a task or course of action to be performed; and PoZiczy--a commitment to action to reach a goal. Policy statements are the most important aspect of land use planning. According to the CAMA Land Use Planning Guidelines (15 NCAC 7B effective September 1, 1979),policy statements must be included which cover four broad categories. In order to accomplish this and to provide the reader with the necessary information, the following format is used. First, under each of the four categories there is a listing and where appropriate, a discussion of the current and future planning issues confronting the Town of Indian Beach. Second, immediately following the issues, there is a discussion of various alternative solutions. Third, considering all information presently available and the best interest of the whole community, a statement reflecting the selected alternative is made. Once this Land Use Plan is adopted by the Indian Beach Board of Commissioners, the statements become the Town's land use policy. A. Resource Protection The most important natural resource in Indian Beach is the island itself, which contains five areas of environmental concern which fall under two systems: Ocean Hazard System and Estuarine System. These systems are dynamic, hazardous to certain kinds of development; and, yet, responsible for the island's attractiveness. Ocean Hazard System represents a dynamic zone due to the constant forces exerted by waves, winds, and currents upon the unstable sands that form the shore. During storms, these forces are intensified and cause significant changes. Hazard area property is in the ownership of a large number of private individuals as well as public agencies and is used by a vast number of visitors. Thus, the Ocean Hazard System is critical because of both the severity of hazard and the intensity of interest. The Estuarine System which.has several components, is the most biologically productive region in this state and nation. It supplies the source of food for fish and shellfish which makes up over 90% of the total value of North Carolina's commercial catch. The system acts as a filter causing suspended organic.and inorganic particles to settle out. The system is also a source of food for native wildlife. Please refer to the detailed discussion under Section I. E. Constraints. Issue A-1. What is the impact of continued deveZopment in the Areas of EnvironmentaZ Concern (AECs)? As noted in Section I. E. 1. a. Ocean Hazard and Estuarine Systems cover a very small geographic area within Indian Beach. Development within the Ocean Hazard System risks life and property. There are standards which if followed will minimize the risk. However, development within the Estuarine System presents a larger risk to the community. Carteret County and Indian Beach have a great deal at stake when activities affect its fishing economy. While in the short term, it may not be noticeable, in the long term, it could be devastating. There are standards which apply to this area too. Enforcement continues to play an important part. 59. Alternative Solutions - Alternative solutions range from no development in an AEC to "business as usual" without an adopted CAMA implementation program. If one feels that natural resources can protect themselves or that a community can survive a "no -growth" policy, then they are apt to select one of these alternatives. The preferred alternative is one that permits development, yet does not ruin the community's future. A-1 POLICY STATEMENT. IN RECOGNITION OF THE ISLAND'S VULNERABLE OCEAN HAZARD SYSTEM AND THE BIOLOGICALLY IMPORTANT ESTUARINE SYSTEM, THE TOWN OF INDIAN BEACH SHALL SUPPORT THE STATE GUIDELINES FOR AREAS OF ENVIRONMENTAL CONCERN (15 NCAC 7H) AND WORK TOWARDS IMPLEMENTING THE MINOR PERMIT PROGRAM (15 NCAC 7E). Issue A-2. What is the impact of continued deveZopment on soiZs unsuitable for urban type deveZopment without the necessary facilities? Most of the undeveloped land in Indian Beach consists of two soils: Newhan fine sand (#21) and Newhan-Corolla Complex (#22). From the interpretive chart, we see that these soils for urban use are rated "slight" for Newhan fine sand, although sandy soils are highly pervious with questionable filtering capacities and "slight" and "severe" for Newhan-Corolla Complex depending on which particular soil is most present. "Slight" means that soil properties are generally favorable for the stated use. Severe means that soil properties are unfavorable and that limitations resulting from the properties may be too difficult to correct or overcome. Soils having this rating require major soil reclamation or special design for stated uses. Soils rated slight are qualified because of the highly pervious sand and consequently, questionable filtering capacity. The cost of property on Barrier Islands may make the modification more economically feasible. Indian Beach's economy is tourism and commercial and port fishing related. All of the community's water supply comes from ground water resources. The agency charged with protecting the community's health at the local level is the Carteret County Health Department. However, the Town has the authority to adopt and enforce stricter standards in order to protect its health. Generally, when the problem becomes known --it's too late. Alternative Solutions - Alternative solutions to minimize risk include eliminating conventional septic tanks as a means of waste disposal and requiring a public sewer system or do nothing. Considering the size of Indian Beach, neither one of these options offer a realistic solution to a sub- stantial health risk. However, the community could demonstrate a greater concern for this potential problem. The Town has the authority to adopt and enforce stricter standards than those used by the County Health Department. Standards could be added to account for high water table, pervious soils and others. While the County Health Department rules are State Regulations, their interpretation and enforcement must by necessity encompass a large area which may not in the long term be in the best interest of Indian Beach. At a minimum, the Town could, through the building inspection permit system, review current application of standards. Newly designed individual waste disposal systems, so called, "experimental system" such as "low pressure", "mound system" and others offer possible solutions. As for multi -family and large development projects, the Town should require package treatment plants. A-2 POLICY STATEMENT. THE TOWN OF INDIAN BEACH IS AWARE OF ITS SOIL LIMITATIONS AND THE POTENTIAL RISK ASSOCIATED WITH WATER SUPPLY. CONSEQUENTLY, THE TOWN WILL REVIEW WITH THE CARTERET COUNTY HEALTH DEPARTMENT ITS CURRENT STANDARDS AND THEIR APPLICATION TO INDIAN BEACH. ADDITIONALLY, THE TOWN WILL SEEK FROM LOCAL, STATE AND FEDERAL AGENCIES ALL AVAILABLE INFORMATION REGARDING THE NEW "EXPERIMENTAL SYSTEMS." IT SHALL BE THE POLICY.OF INDIAN BEACH TO PROTECT ITS GROUND- WATER RESOURCES BY THOROUGHLY CONSIDERING SOIL LIMITATIONS WHEN ISSUING PERMITS. Issue A-3. What is the impact of a continuous Zoss of maritime forest? As noted under Section I. E., maritime forest play an indispensable role in supplying groundwater and holding the island together. Inhabitants of the island should no longer consider these forest as scrub thickets which serve no useful purpose. 61 Alternative Solutions - Alternative solutions are a matter of an adjustment in attitude. We either recognize their importance or continue to disregard current information. Maritime forest are not currently classified as an AEC because of problems in delineation and uniform application of standards to protect various tree species. The future growth and development of the community will require the loss of some vegetation. A-3 POLICY STATEMENT. INDIAN BEACH RECOGNIZES THE IMPORTANCE AND VALUE OF THE MARITIME FOREST. THE TOWN WILL MINIMIZE TO THE EXTENT PRACTICAL THE LOSS OF THE MARITIME FOREST. THE TOWN WILL ENCOURAGE PRIVATE PROPERTY OWNERS TO DISTURB ONLY THAT AREA REQUIRED FOR BUILDINGS, ACCESS, PARKING, AND WASTE DISPOSAL. Issue A-4. To what extent is the threat to life and property in the event of a hurricane due to limited evacuation routes, numerous mobile homes and structures which do not meet State Building Codes? Indian Beach is located on Bogue Banks. This island is fortunate to have higher elevation than other barrier islands. Also, in its favor are the recent road improvements to N.C. 58. However, this road is the only route available in order to leave the island. On the negative side is the doubt whether the improved road facility has the capacity to accommodate the seasonal peak population during late summer and early fall. Past building and development practices which allowed the complete leveling of the island from ocean to sound (i.e., pier) severely weakened the island. In fact, this may have created a manmade washover. Furthermore, Bogue Banks faces north -south and generally hurricanes originate in the south and travel in mostly a norther%y direction. Should a hurricane hit the island directly, it has the potential for intense destruction compared to those islands which face east -west. There has been and probably will continue to have a group seeking an additional bridge from the mainland to Bogue Banks. Recent N.C. Department of Transportation planning studies have shown a proposed crossing near Morehead City and Pine Knoll Shores. While this would improve the evacuation of the island with continued growth and development, it may not be that much of an improvement for Indian Beach. 62 The sheer number of mobile homes in Indian Beach is not comforting in regard to safety from hurricanes. New mobile homes on new lots are required to meet certain standards which they may meet. Are mobile homes which replace previously existing ones required to meet these standards? Alternative Solutions - Indian Beach can recognize these risk or pretend they don't exist. There can be no mistake that living on a barrier island imposes some risk. A-4 POLICY STATEMENT. THE TOWN OF INDIAN BEACH ACKNOWLEDGES THE RISK TO LIFE AND PROPERTY ON THE BARRIER ISLANDS. AS A CONSEQUENCE, INDIAN BEACH SHALL VIGOROUSLY ENFORCE THE STATE BUILDING CODE PARTICULARLY APPENDIX D - WINDSTORM RESISTIVE AMENDMENTS: AND CONDUCT INFORMATION AND EDUCATION.PROGRAMS TO ALERT CITIZENS OF THE HAZARDS AND EVACUATION PLANS. Issue A-5. Are existing Zand use controZ measures adequate to require appropriate uses and activities on the island? Land use control measures are the tools used by local governments to implement policy. The measures are not generally designed to stop development as its critics claim. They are designed to give order and guidance to growth so local government can make the needed improvements and adjustments to provide necessary services. Alternative Solutions - As was discussed under Section I. D., Current Plans, Policies and Regulations, there are serious flaws in the two land use control ordinances. These deficiencies can easily be corrected. A-5 POLICY STATEMENT. THE TOWN OF INDIAN BEACH SUPPORTS THE DEVELOPMENT CONTROL PROVIDED BY LAND USE CONTROL ORDINANCES. IT IS THE POLICY OF THE TOWN TO PERIODICALLY REVIEW THESE ORDINANCES TO ELIMINATE ANY SHORTCOMINGS WHICH LESSEN THEIR EFFECTIVENESS. 63 Issue A-6. Is there management capability to insure the wise use of the istand's resources? This is a very sensitive question since it deals with people and their performance. The management capability of the Town is not confined to just the Town Board. While they. shoulder the ultimate responsibility, full-time personnel, advisory groups and the general populace all have responsi- bility in this area. Considering all factors such as the size of the community, its history, the tax rate and the reason for incorporation, it is doubtful that Indian Beach has the management capability to insure the wise use of the island's resources. Alternative Solutions - There are many alternatives available. They range from the results of voting booth action to the hiring of qualified personnel and consultants. In between, there are less forceful actions which over a longer period may provide the needed change. One possibility is the formation of a Property Owners Association. The Property Owners Association could be the needed stimulus to improve management. Another possibility is to share resources with other Bogue Banks communities. Problems facing Indian Beach are not confined to just this Town. There are problems facing all beach communities. If properly organized, communities can benefit from joint management teams, building inspection and many other services. A-6 POLICY STATEMENT. IN THE FUTURE, INDIAN BEACH SHALL INVESTIGATE THE ADVANTAGES FROM INTERGOVERNMENTAL COOPERATION AGREEMENTS FOR ALL SERVICES. Issue A-7. Does the community suffer from the unavailabitity of flood insurance and fZoodpZain management techniques because of non -designated flood hazards (FederaZ Emergency Management Agency)? Federal Flood Insurance is presently not available to property owners in Indian Beach. First, FEMA must designate the community as having flood hazards. Once designated, the community must enroll in the program. If that enrollment does not take place, then the community would not be afforded direct federal grants and loans (FHA and VA) nor would 64 disaster assistance for permanent reconstruction be available for flood prone areas of the community. With the insurance available, the community has to adopt floodplain management criteria to reduce potential loss of life and property. What the community suffers in the short-term is the security provided knowing flood insurance will reduce one's loss of property. In the long-term, the community may be allowing development which would have the effect of increasing the damage and loss should a hurricane hit. Alternative Solutions - Since the community is on a barrier island, in all probability, it does have a flood hazard. The community could probably enroll in the program without the lengthy process of identifying hazards in a Flood Hazard Boundary Map. This would afford a minimal amount of insurance available before FEMA conducts further study. Some would argue the wisdom of flood insurance because it is a federal program utilizing tax dollars to lessen the risk for people who build in hazardous places. However, as long as disaster assistance is available and costing millions, this program is the only preventive medicine available. It is not likely in the foreseeable future that the demand for waterfront property will wane. A-7 POLICY STATEMENT. THE TOWN OF INDIAN BEACH SHALL CONTACT THE FEDERAL EMERGENCY MANAGEMENT AGENCY ABOUT ENROLLING IN THE NATIONAL FLOOD INSURANCE PROGRAM. Issue A-8. Are the community's cuZturaZ resources being managed? There are several types of cultural resources: archaeological, architectural and historical. Archaeological resources appear to offer the greatest potential to present day Indian Beach. A-8 POLICY STATEMENT. THE TOWN OF INDIAN BEACH RECOGNIZES THE IMPORTANCE OF ITS ARCHAEOLOGICAL REMAINS, BOTH HISTORIC AND PREHISTORIC. IT IS THE TOWN'S POLICY THAT ALL LAND DISTURBING ACTIVITY SHALL GIVE DUE CONSIDERATION TO THE POTENTIAL EXISTENCE OF ARCHAEOLOGICAL REMAINS. IF FOUND, THE TOWN WILL ENCOURAGE THE PRESERVATION OF SUCH RESOURCES. 65 B. Resource Production Resource production at Indian Beach acknowledges the relationship between our natural environment and our man-made environment. Resource production refers to the harvesting of marine resources in the waters of Indian Beach and the intangible resources of the "beach" which provides pleasure to so many. It is important that man's activities are in harmony with the natural conditions. Issue B-1. Does the Town recognize the value of commercial and recreational (sport) fisheries to the community, county, state and nation? Conversations with permanent residents reveal that while they are not knowledgeable about all the biological intricacies, they are informed about certain aspects. The value of recreational fisheries and tourism as a result are more difficult to pin- point. In 1979, the commercial value of marine fisheries excluding menhaden and threat herring in Carteret County equalled 47 million pounds and was valued over 15 million dollars. Consequently, fisheries resources is important to the municipality's and county's economy. Alternative Solutions - Whether it is considered a problem or an opportunity, before one can capitalize - on opportunities, one must recognize its full potential. B-1 POLICY STATEMENT. IT IS THE POLICY OF INDIAN BEACH TO BE COGNIZANT OF THE VALUE OF COMMERCIAL AND RECREATIONAL FISHERIES TO THE COMMUNITY, COUNTY, STATE AND NATION. TO THIS END, THE TOWN WILL SOLICIT THE PROGRAMS OFFERED TO THE COMMUNITY BY VARIOUS INSTITUTIONS AND AGENCIES IN CARTERET.000NTY TO KEEP THEM INFORMED ON THE VALUE OF THESE RESOURCES. Issue B-2. What are the most productive areas? Where are they Zocated? . The most biologically productive area is the estuarine system as noted in Section I. E. 1. e. Also, the public trust waters of the ocean are biologically productive but to a lesser extent. Equally important as a productive area is the entire barrier island, which enables our tourism and leisure time activities to flourish while other sectors of the economy are less fortunate. Even though tourism and leisure are less dependent on natural resources, their successfulness is directly related to the condition of the natural resources. Alternative Solutions - Alternative solutions to preserving the productivity of these resources involve governments at all levels. At the local level, an awareness of the importance of these resources initially may have more influence than the most eloquent worded resolution. The lack of interest on the part of municipal government is just as much policy and direction to other governmental entities as a well written ordinance. B-2 POLICY STATEMENT. INDIAN BEACH IS WELL AWARE OF ITS MARINE AND AESTHETIC RESOURCES. BECAUSE THE COMMUNITY IS A SEASONAL HOST TO RESIDENTS OF OUR STATE AND OTHER STATES BY NECESSITY, IT MUST BE DILIGENT AT EFFORTS TO MINIMIZE ADVERSE IMPACTS ON THESE RESOURCES. Issue B-3. How important is.access and the use of off -road vehicZes in Indian Beach? Section I. B. Present Population and Economy, describes the seasonal economy particularly, the recreational (sport) fisheries and tourism. While many fishermen utilize the piers just as many enjoy surf fishing. Therefore, beach access and associated off -road vehicle (ORV) use is an attraction upon which Indian Beach depends. Nevertheless, vehicular and pedestrian paths cause degradation to sand dunes and vegetation and in certain cases are disruptive to wildlife. Alternative Solutions - Alternative solutions are: ban off road vehicles and pedestrian crossings altogether; designate specific accesses and construct walkovers and parking areas and all-weather road bases; or do nothing. 67 B-3 POLICY STATEMENT. INDIAN BEACH RECOGNIZES ITS ATTRACTION TO RECREATIONAL FISHERMEN BECAUSE OF ITS ACCOMMODATION FOR BEACH USERS AND SURF FISHERMEN. HOWEVER, INDIAN BEACH HAS ONE VEHICLE ACCESS ON BOGUE BANKS AND IT DOES NOT DESIRE TO HAVE MORE OF THEM. INDIAN BEACH SHALL SUPPORT AND CONTINUE TO COOPERATE WITH CARTERET COUNTY OFFICIALS IN THE "POLICING" AND ADMINISTERING THE ONE PUBLIC VEHICLE ACCESS POINT. Issue B-5. Hots can Indian Beach maintain its attractiveness in the face of increasing leisure time activities? Is the community's liveability being threatened? These is no doubt that growth and development change communities --sometimes for better, sometimes for worse. Development in communities tends to be incremental -- one project at a time. If not considered carefully, the cumulative effect can be drastic. Depending on one's definition of liveability and perception of the community, any change could threaten a community. Indian Beach's attractiveness is its abundance of commercial establishments, pier, and pier related businesses, avail- ability of mobile homes sites, residential commercial fishermen and self-reliant natives, and beach access. While these characteristics are not attractive to everyone, they are obviously attractive to those who have settled there. Considering this fact, the only threat is the congestion brought about by increasing numbers of people and the pollution which results. Alternative Solutions - If Indian Beach opted for a "no -growth" policy, there probably wouldn't be the need to do anything. This is very unlikely. We know that the island will grow and develop. In fact, the community wants this to occur. Consequently, our existing and new regulations will by necessity require increased protection to the natural systems which support our lifestyle. Not only will we have to be concerned with the traditional (i.e., building codes, water supply, sewer disposal, wetland protection), but, also storm water runoff, compatibility, intensity, and spacial arrangement of land uses, parking space, and vehicular circulation patterns. B-4 POLICY STATEMENT. THE TOWN OF INDIAN BEACH IS AWARE OF ITS ATTRACTIVENESS AND THE REASONS BEHIND IT. THE TOWN RECOGNIZES THAT WITH ANY GROWTH, ONE'S LIVEABILITY IS THREATENED. IT SHALL BE A POLICY OF INDIAN BEACH TO ELIMINATE THOSE ACTIVITIES WHICH DO NOT COMPLEMENT ITS GOALS AND OBJECTIVES. FURTHERMORE, THE TOWN SHALL BEGIN IN EARNEST TO REVIEW ITS EXISTING REGULATIONS TO PROTECT THE ISLAND'S NATURAL SYSTEMS. NEW REGULATIONS WILL BE REVIEWED TO PROVIDE PROTECTION OF HEALTH, SAFETY AND WELFARE FOR PRESENT AND FUTURE GENERATIONS. 69 C. Economic and Community Development The livelihood of the community's citizens determines much of what kind of place it is and what future shape to expect. Before there is a discussion of specific issues, there should be an under- standing about the origin of the Town of Indian Beach. Indian Beach was incorporated in 1973. The paramount reason for incorporating appears to have been in order to provide available land for the establishment of commercial land uses. It.seems that neighboring communities --Emerald Isle and Pine Knoll Shores --have restrictive covenants and local land use controls which prohibited commercial property -except where it already existed. Thus, the lack of commercial property and the defining of rented mobile homes as a commercial use effectively prohibited the placement of mobile homes on much of the barrier island. With the increasing demand for commercial services and the possibility of annexation by Emerald Isle, Indian Beach became a reality. It should be pointed out that while it is referred to as commercial land uses, the major activity of renting and leasing of mobile homes is residential in use. In actuality, the renting or leasing of a mobile home does not constitute commercial enterprise for land use purposes. According to various North Carolina court cases, mobile homes are considered single family dwellings. Industrial development is not permitted since the Zoning Ordinance does not contain an appropriate district. Even if it did, it is highly unlikely to occur in view of the cost of land. Issue C-1. How much growth and development does the Town desire? According to the 1976 Land Development Plan, when citizens were questione"Would you like to see Indian Beach remain much the same as it is now?"-- 70 118 said yes while only 24 said no. In conversations with the same residents today, it seems that they share the same feelings as in 1976. Yet, by all indications, the island and the Town continue to develop at full speed. Probably more important is the question, "How much development can the Town of Indian Beach withstand? This is a difficult and complex question because there appears to be no authority on "carrying capacity." "Carrying capacity means the ability of natural and man-made systems to support the demands of various uses and that it refers to inherent limits in the system beyond which change cannot be absorbed without producing instability, degradation or irreversible damage." The most difficult task is to determine the relation- ship between the resources and the waste loads which can be absorbed in advance.* That would require the capability beyond the scope of this land use plan. However, we can observe and monitor indicators of environmental degradation. One such indicator might be the closure of shellfish waters along our sounds and creeks. Alternative Solutions - There are two basic alternatives. One alternative is to do nothing. A second alternative is to provide the basic services in which an urban set- ting demands. In between is an option which doesn't eliminate the problem but is in keeping with the resources at hand. This option involves the planning for municipal services to support present and future generations. This would include the revising and adopting of new land use controls which are designed to protect the natural re- sources system upon which the island is so dependent. C-1 POLICY STATEMENT. THE TOWN OF INDIAN BEACH SUPPORTS THE CONTINUED GROWTH AND DEVELOPMENT OF THE COMMUNITY. HOWEVER, THE TOWN RECOGNIZES ITS ROLE AND RESPONSIBILITY. * Journal of Soil and Water Conservation, "Carrying Capacity: A Key to Environmental Planning? Ju y-August 1975, David R. Godschalk and Francis H. Parker 71 TO PROTECT THE PUBLIC HEALTH, WELFARE AND SAFETY. CONSE- QUENTLY, THE TOWN IS COMMITTED TO THE PROVISION OF BASIC MUNICIPAL SERVICES. TO THIS END, THE TOWN SHALL CONSIDER AS AN INTERIM POLICY THE FEASIBILITY OF ALTERNATIVE WASTE DISPOSAL MEANS AND THE REVISION OF LAND USE CONTROLS WHICH WILL PROTECT THE NATURAL RESOURCES. Issue C-2. What type of commercial uses are desired? Commercial activities are important in defining the type of community. Obviously, there is quite a difference between family -oriented billard halls and the.traditional poolroom/ tavern. Furthermore, these two examples attract different clientele. Motels and boarding houses tend to attract more overnight guests than beach cottages and condominiums. Indian Beach is noted for its excellent fishing. Restaurants and marine accessory or related activities compliment the existing tourist/fishing visitor. Other possibilities are sail and power boat rentals, marine gift shops, and laundry facilities that are water dependent or related. Alternative Solutions - Alternative solutions differ only in the degree of commitment to solving the problem. Beyond just recognizing the issue that commercial activities have a lot to do with the type of people and activities that the community attracts, Indian Beach can modify its permitted and conditional uses in the commercial zoning districts to reflect the preferred activities. C-2 POLICY STATEMENT. INDIAN BEACH RECOGNIZES THE LINK BETWEEN PERMITTED COMMERCIAL ACTIVITIES AND THE FUTURE TYPE OF COMMUNITY RESULTING THEREIN. INDIAN BEACH SHALL REVIEW VERY CRITICALLY ITS PERMITTED AND CONDITIONAL USES OF THE COMMERCIAL ZONING DISTRICTS. IT IS THE POLICY OF INDIAN BEACH TO ENCOURAGE AND PERMIT ONLY THOSE COMMERCIAL ACTIVITIES WHICH COMPLIMENT A FAMILY VACATION RESORT COMMUNITY. Issue C-3. Where shouZd growth and deveZopment occur? Indian Beach is a small community within which a limited amount of new.growth can occur. We have seen from the section on 72 Constraints that there are a number of limiting factors: soils; natural systems, i.e., dunes, estuarine waters, maritime forest; limited facilities and little growth management capability. Consequently, the question is not so much where growth and development occur but should it occur with all the limiting factors at work. Alternative Solutions - This issue as in many cases becomes one of economics. Indian Beach would have less worry if all basic municipal services were in operation. Since that is not the case, then there are two options: a non -growth policy or an interim policy until the basic services and facilities are available. The latter is possible only if private development shares in providing those services and facilities. For instance, it may be possible to have several packaged wastewater treatment and disposal plants rather than the traditional, one -large municipal system. To enable the development of these "new" systems, the Town will have to give careful consideration to the existing development pattern and the resulting high densities. Higher densities make the packaged plants economically feasible. C-3 POLICY STATEMENT. IT IS THE OBJECTIVE OF INDIAN BEACH TO PROVIDE THE BASIC MUNICIPAL SERVICES REQUIRED OF AN URBAN DEVELOPMENT PATTERN. UNTIL SUCH TIME THAT PUBLIC WASTEWATER TREATMENT AND DISPOSAL ARE AVAILABLE, INDIAN BEACH SHALL VIGOROUSLY ENFORCE PLANNING AND DEVELOPMENT STANDARDS REQUIRED OF LOCAL, STATE AND FEDERAL AGENCIES. ALSO, INDIAN BEACH SHALL REVIEW ITS LAND USE CONTROLS TO DETERMINE THEIR CONSISTENCY WITH CAMA AND OTHER REGULATORY PROGRAMS. FURTHERMORE, INDIAN BEACH SHALL RECONSIDER THEIR DENSITY STANDARDS (ZONING - LOT SIZE) AND THE EFFECT THAT THEY PLAY ON THE AVAILABILITY OF PRIVATE PACKAGED WASTEWATER TREATMENT AND DISPOSAL PLANTS. Issue C--4. Since mobile homes are the least permanent structures, what effect will increasing land value have on them? We have noted that mobile homes are classified as personal property under North Carolina tax law. From the community's viewpoint, this is unfortunate because personal property declines in value each year. Therefore, the community would receive less tax revenue each year. While the mobile home is decreasing in value, the land that it occupies is increas- ing in value. This is evident by the recent (1981) Carteret County reevaluation. As a consequence, mobile homes in years to come may not provide the return on investment as the land increases in value. Present undeveloped land is just too expensive to locate mobile homes on. It is not clear that increasing land value is necessarily 73 a problem. However, it does pose a dilemma to mobile home park operators and owners. Investments in facilities made by the owners and operators for mobile homes may not be suitable for other more permanent type residential land use. As a result, the mobile home park owners and operators or the Town.can be proactive and determine what is best for the community as a whole. C-4 POLICY STATEMENT. THE TOWN OF INDIAN BEACH RECOGNIZES THAT MOBILE HOMES ARE NOT ONLY VULNERABLE TO NATURAL FORCES BUT ECONOMIC FORCES AS WELL. THUS, THE TOWN CONSIDERS MOBILE HOMES AS AN INTERIM TYPE LAND USE ACTIVITY AND THAT FUTURE PLANS WHICH INVOLVE THE TOWN WILL TAKE THIS INTO ACCOUNT. Issue C-5. To what extent is the local government committed to providing services? Local government in a nutshell is founded to provide services that private interests are unwilling to provide. Their motive is to provide services at a reasonable cost. Like all businesses, it costs money to operate and generally a limited amount of revenue is. available. Local government through the democratic process has to detrmine its own priorities of -service. Alternative Solutions - There are three basic levels of commitment as described as follows. First, plans and studies some of which cost money to the Town represents one level of commitment. Adopted policies and the will to carry them out are another. The strongest commitment that the Town can have is to levy a tax to provide a facility or service. C-5 POLICY STATEMENT. THE TOWN OF INDIAN BEACH IS COMMITTED TO PROVIDING BASIC SERVICES AS DEMANDED BY AN URBAN DEVELOPMENT PATTERN. THE TOWN SHALL CONTINUE TO INVESTIGATE THE COST EFFECTIVE ALTERNATIVES TO PROVIDING THESE SERVICES. Issue C-6. What is Indian Beach's ability to provide the services and facilities? What effect does personal property vs. real property have in terms of ability to pay? Indian Beach was incorporated in 1973. As recently as 1978, 74 Indian Beach was considered an inactive community because it did not perform those municipal functions necessary to qualify for State Street - Aid Allocation. In 1979, the Town's total valuation amounted to 6.6 million dollars. Combined with a 25� tax levy, this contributed $16,617 revenue to the general fund. As noted earlier, Indian Beach is primarily a residential resort community with a preponderance of mobile homes. Mobile homes are classified as personal property which decline in value. Alternative Solutions - There does not appear to be any short term solution. In the long term, the community can either disregard these basic facts of local government financing or they can be given due consideration in the course of evaluating future development decisions which impact the entire community. C-6 POLICY STATEMENT. INDIAN BEACH RECOGNIZES ITS CONSTRAINTS TO PROVIDING SERVICES. IT SHALL BE THE POLICY OF INDIAN BEACH TO ENCOURAGE A VARIETY OF PERMANENT RESIDENTIAL AND COMMERCIAL STRUCTURES TO LOCATE WITHIN THE TOWN'S BOUNDARIES.. Issue C-7. How committed is Indian Beach to various State and Federal programs such as flood disaster assistance, erosion control and beach nourishment, pubZic access, dredging, channeZ maintenance and waste water control? With the exception of public access, all require large outlays of public money generally only available from Federal and State governments. Unless the local government can provide the funding, its only recourse is to prevent a situation from occurring which would result in the need to spend large sums of money. Obviously, natural events cannot be prevented. Steps can be taken to limit damage in the event of a disaster. Alternative Solutions - As was noted earlier, there are several levels of commitment. To date, Indian Beach has participated in wastewater control planning (201) and has cooperated with Carteret County in public access. 75 C-7 POLICY STATEMENT. CONSIDERING ALL THE NEEDS OF INDIAN BEACH, THE LIMITED RESOURCES AVAILABLE AND THE LONG-TERM IMPACT, WASTEWATER CONTROL HAS TO BE A TOP PRIORITY FOR FUNDING. OTHER PROGRAMS CAN BE INITIATED WHICH ARE NOT CAPITAL INTENSIVE AND CAN BE IMPLEMENTED WITH THE FOLLOWING INDIAN BEACH POLICIES ON FEDERAL AND STATE ASSISTANCE. FLOOD INSURANCE. INDIAN BEACH SHALL FORMALLY REQUEST FROM ! THE ODE L EMERGENCY MANAGEMENT AGENCY, THE DETERMINA- TION OF THE DEGREE OF FLOOD HAZARD TO THE COMMUNITY IN THE EVENT OF A 100 YEAR STORM. EROSION CONTROL AND BEACH NOURISHMENT. INDIAN BEACH SHALL IMPLEMENT HE MINOR PERMIT PR CEDURES OF THE COASTAL AREA MANAGEMENT ACT AND THE DEVELOPMENT STANDARDS REQUIRED IN AREAS OF ENVIRONMENTAL CONCERN. THIS WILL REDUCE THE NEED FOR EROSION CONTROL AND BEACH NOURISHMENT. PUBLIC ACCESS. INDIAN BEACH SHALL SUPPORT THE PUBLIC'S RIGHT TO ACCESS AT DESIGNATED POINTS. DREDGING AND CHANNEL MAINTENANCE. INDIAN BEACH RECOGNIZES HE NEED FOR PERIODIC MAINTENANCE DREDGING. THIS COST SHALL BE BORNE BY THE PRIVATE INTEREST WHICH IT SERVES. WASTEWATER CONTROL. INDIAN BEACH REALIZES THE IMPORTANCE AND PRIORITY OF THIS FEDERAL AND STATE ASSISTED PROGRAM. INDIAN BEACH SHALL WORK DILIGENTLY TO FULFILL THIS NEED AS COST EFFECTIVE AS POSSIBLE. Issue C-8. What is the community's reaction to finger canaZ development? Finger canal development increases the number of waterfront lots. They also destroy natural habitat for wildlife and marine organisms. They reduce the area which buffers the island in storm conditions and increase the chance of overwash. They lessen the natural physiological capacity of wetlands to assimilate waste attributed to runoff. They eventually need to be maintained which often times is overlooked by both the developer and property owner. Alternative Solutions - They are really only two alterna- tives available. Either they are permitted or prohibited. 75 C-8 POLICY STATEMENT. IT IS THE POLICY OF INDIAN BEACH TO PROHIBIT THE CONSTRUCTION OF ANY NEW FINGER CANAL DEVELOPMENTS. Issue C-9. Horn does the eonmrunity regard energy facility siting such as nueZear poser pZants, oiZ refineries and oiZ transportation facilities? Owing to geography, it is very doubtful Indian Beach or Bogue Banks for that matter would be the site for a nuclear power plant or oil refinery. It is conceivable that Indian Beach could be in the right -a -way path for energy products transmission lines such as oil or gas pipelines. These facilities can be very disruptive to a residential beach community. Alternative Solutions - The general welfare and public interest of the nation, state and community require that a reliable source of energy be made available to its citizens. However, unwise development of energy facilities can have an adverse effect upon the local community. Thus, there are two very strong interests to be served. Any solution would have to entail a balance between the public benefits of energy development and protection of our valuable coastal resources. C-9 POLICY STATEMENT. APPLICANTS FOR ENERGY FACILITY SITING IN INDIAN BEACH SHALL DISCLOSE TO THE TOWN ALL COSTS AND BENEFITS (ECONOMIC, SOCIAL, ENVIRONMENTAL) ASSOCIATED WITH THE PROJECT. SHORELINE SITING OF FACILITIES WILL BE ACCEPTABLE ONLY IF IT CAN BE DEMONSTRATED THAT COASTAL WATERS WILL BE ADEQUATELY PROTECTED, THE PUBLIC'S RIGHT TO ACCESS WILL NOT BE UNREASONABLY RESTRICTED AND ALL REASONABLE MITIGATING MEASURES HAVE BEEN TAKEN TO MINIMIZE IMPACTS TO AECs. 77 D. Public Participation Public participation is more than a worthy goal. Public participation insures that the best decision will be made by first, informing the public --and then, soliciting their involvement. The right for public participation is mandated to a limited extent in the state's open meetings law. Public participation should be pur- sued not only in land use planning but in all local government decision making. This Land Use Plan for Indian Beach was developed with the benefit of two participatory techniques --a survey/questionnaire and advertised public meetings. The survey was conducted several years ago. In view of the size of Indian Beach (1980 population - 54, and 1979 budget - $16,617) and the average return rate for surveys, it was decided that the advertised public hearing would be the best method. The results of the earlier survey and a current discussion of issues were the agenda for the advertised public meeting. Approxi- mately 25 percent of the Town Is permanent residents were in attendance. This public meeting took place on February 3, 1981. Response from that meeting was incorporated into the draft land use plan. Another public meeting was held August 12, 1981, to discuss the pre- liminary draft of the Indian Beach Land Use Plan. Members of the Town Board of Commissioners and interested citizens and property owners asked many questions and suggested several changes. Subsequent to that meeting, the Mayor and the Planner -in -Charge drafted revisions to the preliminary draft. The preliminary draft with revisions was submitted to the Coastal Resources Commission on September 29, 1981. Comments from the Coastal Resources Commission on the pre- liminary draft were received December 18, 1981. Corrections, suggest- ions and revisions were incorporated into a revised draft dated March 1982. A public hearing was advertised March 24, 1982, and held by the Town on April 21, 1982. Comments were received and made a part of the Land Use Plan as an addendum. Another public hearing was advertised May 5, 1982, and held on June 9, 1982. 78 Issue D-1. How can Indian Beach best educate the public of the issues? The better informed the community, the more likely that there will be better decisions. The task is not easy in a beach community because of absentee property owners. 78A Alternative Solutions - Beside the traditional questionnaire surveys and plan summaries, the community could benefit from an active property owners association and/or planning board. These organizations could meet on weekend holidays semi-annually to discuss important issues in the community. D-1 POLICY STATEMENT. INDIAN BEACH SHALL APPOINT ACTIVE COMMUNITY MINDED CITIZENS TO ITS ADVISORY BOARDS SUCH AS THE PLANNING BOARD. THE TOWN WILL ALSO ENCOURAGE THE FORMATION OF A PROPERTY OWNERS ASSOCIATION. Issue D-2. How can Indian Beach soZicit the individuaZ's invoZvement? Unless an issue affects an individual, they are not likely to become involved. Alternative Solutions - Traditionally, advertisements, night meetings and spot announcements on the electronic media have been utilized to solicit involvement. These efforts along with a better description of problems confronting the community could increase attendance at public informa- tional meetings. D-2 POLICY STATEMENT. INDIAN BEACH RECOGNIZES THE BENEFITS - DERIVED FROM AN INFORMED POPULACE. INDIAN BEACH SHALL SPONSOR MEETINGS (OTHER THAN REGULARLY SCHEDULED MEETINGS) TO SOLICIT CITIZENS' OPINIONS ON ISSUES. THESE MEETINGS WILL BE GIVEN ADVANCED NOTICE. Issue D-3. How can Indian Beach have pubZic participation on a continuing basis? A lot depends on the officials' attitude toward public participation. If the Town welcomes and even encourages public participation, it will most likely increase. D-3 POLICY STATEMENT. IT IS THE POLICY OF INDIAN BEACH TO WELCOME AND SOLICIT THE PUBLIC'S INVOLVEMENT IN REGARD TO THE TOWN'S BUSINESS ON A CONTINUING BASIS. 7.9 III. LAND CLASSIFICATION The land classification system provides a framework to be used by local government to identify the future use of all lands in their jurisdiction. The designation of land classes allows the local government to illustrate their policy statements adopted in Section II. This illustration describes where and to what density (intensity) Indian Beach wants growth to occur and where they want to conserve natural and cultural resources by guiding growth. Although specific areas are outlined on the Land Classification Map, it must be remembered that land classification is a tool to help implement policies and'since it requires local government and Coastal Resources Commission's approval for amendments, it has the effect of a regulatory mechanism. It also provides guidance to regulatory agencies for permit issuance. The Land Classification System includes five broad categories. Local governments can further subdivide these broad classes into more specific classes if they desire to do so. The five classes are: Developed, Transition, Community, Rural and Conservation. For Indian Beach only three classes: Developed, Transition, and Conservation are applicable. Developed. The purpose of this classification is to provide for continued intensive development and redevelopment of existing cities. Developed is defined as lands currently developed for urban purposes at or approaching a density of 500 dwellings per square mile that are provided with usual municipal or public services including at least public water and sewer, recreational facilities, police and fire protection. Areas which exceed the minimum density but do not have public sewer services may be divided into a separate class. Indian Beach meets the density requirement easily, however, the Town only provides police protection. Water service is provided by Bogue Banks Water and Sewer Authority. Transition. The purpose of the transition class is to provide for future intensive urban development within the ensuing ten years on lands that are most suitable and that will be scheduled for provision of necessary public utilities and services. Lands classified transition may include: (1) lands currently having urban services, and (2) other lands necessary to accommodate the urban population and growth anticipated within the planning M jurisdiction. The existing development in Indian Beach does not qualify for the Developed class and it does not exactly fit the Transition class definition either. Then by necessity, it must be somewhere in between. For our purposes, we will designate this land as Developed without Services (D w/o Ser.). Conservation. The purpose of the Conservation class is to provide for effective long-term management of significantly limited or irreplaceable areas. This management may be needed because of its natural, cultural, recreational, produc- tive or scenic values. The Conservation class should be applied to lands that contain: major wetlands; essentially undeveloped shorelands that are unique, fragile or hazardous for development; necessary wildlife habitat or areas that have a high probability for providing necessary habitat conditions; publicly owned water supply, watersheds and aquifers; and forest lands that are .undeveloped and will remain undeveloped for commercial purposes. In Indian Beach, all applicable Areas of Environmental Con- cern (AECs) are designated or are intended to be designated as Conservation. This would include the Ocean Hazard System AECs and Estuarine System AECs. LAND CLASSIFICATION: RELATIONSHIP TO POLICIES AND APPROPRIATE USES Conservation (C) It is the intent of this Land Use Plan that those lands designated as AECs (15 NCAC 7H) should be designated as Conservation for land classi- fication purposes. This does not preclude development. It does require that uses of land must meet the performance criteria and standards required of the applicable AEC. Moreover, some AEC performance criteria and standards are more strigent than others. For example, the Estuarine Shoreline AEC standards permit single family residential uses whereas the Coastal Wetlands or Public Trust areas would not. However, there is one exception to this Conservation classification and AEC designation which does not appear on either map. There may be an instance where an on -site inspection would reveal the need for a U.S. Army Corps of Engineers' wetland permit (404) which would be beyond the AEC jurisdiction. Since these areas are very site specific, they are not designated as conservation. Appropriate development standards of the U.S. Corps of Engineers would be applicable. Acceptable uses of land in Conservation will vary depending upon the particular AEC represented. See Appendix II. It should be emphasized that Coastal Wetlands and Public Trust Areas would support water dependent uses meeting applicable AEC standards as docks and piers. Whereas, the Estuarine Shoreline Areas and Ocean Erodible Areas would support single family structures meeting applicable AEC standards. 81 Developed without Services (Dev. w/o Ser.) It is the intent of the Indian Beach Land Use Plan that those high - ground areas beyond AECs that are already disturbed or occupied with structures be classified as Dev. w/o Ser. Dev. w/o Ser. is a variation of the Developed category which recognizes the limited services provided by the municipality. Water is available from the Bogue Banks Water and Sewer Corporation. Community sewer service is not available from either the. Town or the Corporation. The lack of a municipal treatment plant and collection system does not automatically mean existing widespread pollution problems for Indian Beach. Much depends on the carrying capacity of the natural system, monitoring by the Town on the installation of septic tanks, periodic maintenance of homeowners with septic tanks and density permitted. The Town must be dilligent in its effort and not take lightly the indicator of pollution (closing of shellfish waters). This is reflected in the Town's policies Section II. 11 Also, this category covers land rated as having very severe soil limitation. This rating is based upon soil characteristics which exist in the soil's natural state. As noted on pages 1g through 26, soil characteristics can be modified. The modification for various uses makes it more expensive to develop. In resort areas such as Indian Beach with skyrocketing property cost, this added cost is not prohibitive. Finally, soils are but one limiting factor and as an individual factor do not constitute "severe physical limitations for urban development". Appropriate uses of land in this category are identified in the land use control ordinances (Zoning, Subdivision Regulations and Mobile Home Ordinance), already adopted by the Town. Generally, a variety of residential, commercial, institutional and recreation uses are permitted. As stated earlier in the discussion above and in Section II, Policies A-1, A-2, A-3, A-4, A-5, A-6, B-2, B-4, C-1, C-2, C-3, C-4, C-5, C-6, C-7 and C-8, the Town seeks to improve its own situation. Transition'(T) The Transition category is all those lands not designated as Conserva- tion or Developed without Services. Essentially, Transition areas are the highground areas which are presently undisturbed, but due to anticipated development in the next twenty years, these areas are logical areas for development and for the provision of services. Some of the area designated as Transition contains soils having severe soil limitation. Please see previous discussion under Developed without Services.There is also a considerable amount of Transition area which contains maritime forest. Maritime forest is not an AEC but is worthy of protection and conservation practices. See discussion on page 51 and Policy A-3 on page 61• 82 Appropriate uses of land in this category are identified in the land use control ordinances (zoning, subdivision regulation, and mobile home ordinance) already adopted by the Town. Generally, a variety of residential, commercial, institutional and recreational uses are permitted. The Town must balance the aspirations and needs of its citizens with the constraints, limitations and resources available to the community. The Policies set forth in Section II is an attempt to balance all these factors.

September 9, 1977. 216 1. .0205 COASTAL WETLANDS 220 la) Descr p on.-- Coastal wetlands are defined as any salt 222 marsh or other marsh sgbject to regular or occasional flooding by 223 tides, including wind tides (whether or not the tide waters reach 224 the marshland areas through natural or artificial watercourses), provided this shall not ,include hurricane or tropical storm 225 tides. goastal wetlands contain some, but not necessarily ail, of the 226 following marsh, plant §pecies: 227 (1) Cord Grass (Spartina alterniflora) , 229 (2) Black Needlerush (Juncas roemerianus), 230 (3) Glassvort (Salicornia spp.) , 231 (4) Salt Grass (Distichlis spicata) , 232 (5) Sea Lavender (Limonium spp.), 233 (6) Bulrush (Scirpus spp-),, 234 (7) Saw Grass (Cladiva jamaicense) , 235 (8) Cat -tail (Typha spp.), 236 (9) Salt Meadow Grass (Spartina patens) , 237 (10) Salt Reed Grass (Spartina cynosuroides(. 236 Included in this definition of coastal wetlands is *such 240 contiguous land as the Secretary of JRSCD reasonably deems 241 necessary to affect by any such order, in carrying out the purposes of this §action. [ G. S. 113-230 (a) ] 242 1b) Significance. The unique productivity of the estuarine 243 system is supported by detritus ,(decayed plant material) and 244 nutrients that are exported frog the coastal marshlands. The .gmount of exportation and degree of importance appears to be 245 variable from marsh to marsh, depending primarily upon its 246 frequency of inundation and inherent characteristics of the various Plant species. Without the marsh, the high productivity 247, levels and complex food chains typically found in the estuaries 249 could not be maintained. ' jjan harvests various aspects of this productivity when he 249 fishes, bunts, and gathers shellfish froa the estuary. Estuarine 250 dependent species of fish and shellfish such as menhaden, shrimp, NORTH CAROLINA ADMINISTRATIVE CODE 06/12/81 7-7 NI&CD - COASTAL MANAGEMENT T 15: 07H .0200 flounder, oysters, and crabs currently sake up over 90 percent of 251 the total value of North garolina°s commercial catch. The 252 marshlands, therefore, support an enormous amount of commercial and recreational businesses along the seacoast. 253 The roots, rhizomes, stems, and seeds of coastal wetlands act 255 as good quality waterfowl Ind wildlife feeding and nesting 256 materials. In addition, coastal wetlands serve as the first line 257 of defense in retarding estuarine shoreline erosion. The plant stems and leaves tend to dissipate gave action, while the vast 258 network of roots and rhizomes resists soil erosion. In fhis way, 259 the coastal wetlands serve as barriers against flood damage and control erosion between Jhe estuary and the uplands. 260 marshlands also act as nutrient and sediment traps by slowing 262 the water which floes over then and causing suspended organic and 263 inorganic particles to settle oat. In this manner, the nutrient 264 storehouse is maintained, and sediment harmful to marine organisms is removed. Also, pollutants and excessive 'nutrients 265 are absorbed by the marsh plants, thus providing an _inexpensive 266 water treatment service. lc) !Management objective. To give highest priority to the 268 protection and management of coastal wetlands so as to safeguard 269 and perpetuate their biological, social, economic and aesthetic values; to coordinate and establish a management system capable 270 of conserving and utilizing coastal wetlands as a natural 271 resource essential to the functioning of the entire estuarine system. 272 ,jd) Use Standards. Suitable land uses shall be those 273 consistent with the management objective fn this Rule. Highest 274 priority of use shall be allocated to the conservation of existing coastal wetlands. Second priority of coastal wetland 275 use shall be given to those types of development gctivities that 276 require water access and cannot function elsewhere. Qnacceptable land uses may include, but would not be limited 277 to, the following examples: restaurants and businesses; 278 residences, apartments, motels, hotels, and trailer parks; parking lots and private roads and highways; and factories. 279 Examples of acceptable land uses may include Itility easements, 280 fishing piers, docks, and agricultural uses, such as farming and forestry drainage, as permitted under North Carolina's Dredge and 281 Fill Act and/or other applicable laws. In every instance, the particular location, use, and design 282 characteristics shall be in accord with the general use standards 283 for coastal wetlands, estuarine waters, and public trust areas described in Rule .0208 of this Section. 284 History Rote: Statutory Authority G.S. 113A-107 (a) ; 287 113A-107 (b) ; 113A-113 (b) (1) ; 288 NORTH CAROLINk ADRIHISTRATrVE CODE 06/12/81 7-8 WR&CD - COMAL.

Estuarine waters are defined in G.S. 113b- 294 113 (b) (2) as Nall the rater of the Jtlantic Ocean within the 295 boundary of north Carolina and all the waters of the bays, sounds, rivers, and tributaries thereto seaward of the dividing 296 line between coastal fishing waters and inland fishing waters, as 297 set forth in an agreement adopted by the Vildlife Resources Commission and the Department of natural Resources and Community 298 Development filed with the Secretary of State, entitled 'Boundary 299 Lines, North Carolina Commercial Fishing -- Inland Fishing 300 haters,' Revised to !larch 1, 1065.0 1b) Significance. Estuarine waters are the dominant component 302 and bonding element of the entire estuarine system, integrating 303 aquatic influences from both the land and the sea. Estuaries Ire 304 among the most productive natural environments of North Carolina.. They support the valuable commercial and sports fisheries of the 305 coastal area which are comprised of estuarine dependent species 306 such as menhaden, flounder, shrimp, crabs, and oysters. These species must. spend all or some part of their life cycle within 307 the estuarine raters to mature and reproduce. of the 10 leading 308 species 'in the commercial catch, all but one are dependent on the estuary. This high productivity associated with the estuary results from 310 its unique circulation patterns gaused by tidal energy, fresh 311 water flow, an3 shallow depth; nutrient trapping mechanisms; and 312 protection to the many organisms. The circulation of estuarine waters transports nutrients, propels 'plankton, spreads seed 313 stages of fish and shellfish, flushes wastes from animal and plant life, cleanses the system of pollutants, controls salinity, 314 shifts sediments, and mikes the water to create a multitude of 315 habitats. Some important features of the estuary include mud and sand flats, eel grass beds, salt marshes, submerged vegetation 316 flats, clam and oyster beds, and important nursery areas. 317 Secondary benefits include the stipulation of the coastal 319 economy from the spin' off operations required to service 320 commercial and sports fisheries, waterfowl hunting, marinas, boatyards, repairs and supplies, processing operations, and 321 tourist related industries. In addition, there is considerable 322 nonmonetary value associated with aesthetics, recreation, and education. jc) Management objective.

Public trust areas are all raters of the 347 Atlantic ocean and the lands thereunder from the mean high water 348 mark to the seaward limit of state jurisdiction; all natural bodies of Water subject to measurable lunar tides and lands 349 thereunder to the mean high water mark; all navigable natural 350 bodies of water and lands thereunder to the mean high water level Sr mean water level as the case may be, except privately -owned 351 lakes to which the public has no right of access; all water in 352 artificially created bodies of water containing significant public fishing resources or other public resources which are 353 accessible to the public by navigation from bodies of water in 354 which the public has rights of navigation; and all waters in 355 artificially created bodies of water in which the public has acquired rights by prescription, custom, usage, dedication, or 356 any other means. In determining whether the public has acquired rights in artificially created bodies of rater, the following 357 factors shall be considered: (1) the use of the body of water by the public, 359 (2) the length of tine the pablic has used the area, 360 (3) the value of public resources in the body of water, 361 S4) whether the public resources in the body of water are 363 mobile to the extent that they can move into natural 364 bodies of water, NORTH CAROLINA ADMINISTRATIVE CODE 06/12/81 7-10 116CD - COASTAL MANAGEMENT T15: 07H .0200 15) whether the creation of the artificial body of dater 365 required permission from the state, and 366 ,J6) the value of the body of water to the public for 367 navigation from one public area to Pnother public area. 368 Sb) Significance. The public has rights in these areas, 370 including navigation and recreation. _Tn addition, these, areas 371 -support valuable commercial and sports fisheries, have aesthetic value, Ind are important resources for economic development. 372 jc) Management objective. To protect public rights for 373 navigation and recreation and to Preserve and manage the public 374 trust_ areas so as to safeguard and perpetuate their biological, econaaic and aesthetic value. 375 sd) Use Standards. Acceptable uses shall be those consistent 376 with the management objectives is 1c) of this Rule. in the 377 absence of overriding public benefit, any use which significantly interferes yith the public right of navigation or other public 376 trust rights which the public may be found to have in these areas 379 shall not be allowed.

As an AEC, estuarine shorelines, although 560 characterized as dry land, are considered a component of the 561 estuarine system because of the close association with the adjacent ,gstuarine waters.- This Section defines estuarine 562 shorelines, describes the significance, and &rticulates standards 563 for development. ,(b) Description. Estuarine shorelines are those non -ocean 564 shorelines which are especially vulnerable to erosion, flooding, 565 or other adverse effects of wind and water and are intimately connected to the estuary. This area extends from the mean high 566 water level or normal water level along the estuaries, sounds, 567 bays, and brackish waters as set forth in an agreement adopted by 568 the. Wildlife Resources Commission and the Department of Natural Resources and Community Development [described in Regulation 569 .0206 (a) of this Section] for a distance of 75 feet landward. 570 NORTH CAROLIHI sDRINISTRATivE CODE 06/12/81 7-16 NBbCD - COASTAL eimieEMENT T15: 07H .0200 ,ic) Significance. Development within estuarine shorelines 571 influences the quality of estuarine life and is subject to the 572 damaging processes of shore front erosion and flooding. ld) Hanagement objective.

The erosion setback line shall 793 be set at a distance of 30 times the long-term annual erosion rate from the first line of stable natural 794 vegetation. In areas where the rate is less than 2 feet per year, the setback line shall be 60 feet from 795 the vegetation line. 42) If a primary dune exists in the ABC on or behind the 796 lot on which the development is proposed, the 797 development shall be landward of the crest of the primary dune or the long-term erosion setback line, 798 whichever is farthest from the first line of stable natural vegetation. For existing dots, however, where 799 setting the development behind the crest of the primary dune would preclude any practical use of the lot, 800 development may be located seaward of the primary dune.

Se) "Vegetation Line" means the first line of stable natural 767 vegetation, which shall be used as the reference point for 768 measuring oceanfront setbacks. This line represents the boundary between the normal dry -sand beach, which is subject to constant 769 flux due to waves, tides, storms and wind, and the pore stable 770 upland areas. It is generally located at or immediately oceanward of the seaward toe of the frontal dune and/or erosion 771 escarpment. In areas where there is no stable natural vegetation 772 present, this line shall be established by connecting or extending the lines from the nearest adjacent vegetation on 773 either side of the site and extrapolation (either on -ground observation or by aerial photographic interpretation) to 774 establish the line.

Any building constructed within the ocean hazard area shall 985 comply with Appendix D, "Windstorm Resistive Construction," of the North Carolina Residential 986 Building Code, except that when any provisions of that mppendix are inconsistent with any of the following ABC 987 standards, the more restrictive provisions shall 988 control. .12) All structures in the ocean hazard area shall be on 989 pilings not less than eight inches in diameter if round 990 or eight inches to a side if square. ,( All pilings shall have a tip penetration greater than 991 eight feet below the lowest ground elevation under the 992 structure. For those structures so located on the 993 primary dune or nearer to the ocean, the pilings 7 roust extend to four feet below mean sea level. j). All foundations shall be adequately designed to be 994 stable during applicable fluctuations in ground 995 elevation and rave forces during a 1.00 year storm. gantilevered decks and walkways shall meet this 996 standard. or shall be designed to Jireak-away without 997 structural damage to the main structure. sS). All pilings shall be appropriately treated to resist 998 decay, insects And corrosion. 999 J6)_ The lowest portion of the structural member of the 1000 lowest floor (excluding the pilings or columns) shall 1001 be elevated to or above the 100 year storm elevation. 17) All exposed structural connections shall be adequately 1002 rustproofed or enclosed. 1003 All utility systems shall be located and constructed so 1004 as to minimize or eliminate storm damage. 1005 NORTH CAROLINA ADBINISTRATIVE CODS 06/12/81 7-28 MRSCO - COASTAL MANAGEMENT T 15: 07H .0300 ,S9) All walls below 100 year base flood level shall be 1006 designed and installed _to: (A) allow storm waters to 1007 rise and flow freely under the structure, JB) not 1008 permit the breakaway walls themselves to become water- borne debris, and JC) not cause the accumulation of 1009 water -borne debris. Break -away walls shall be intended 1010 to collapse under stress without jeopardising the structural support of the structure. _ (10) No impermeable (such as asphalt or cement) surfaces 1011 shall be allowed over any functional part of a complete 1012 septic tank system.
