INTRODUCTION The Town of Beaufort received a Fiscal Year 1996/1997 CAMA Technical Assistance Grant of $29,346.00 to undertake a transportation corridor study and impact analysis for relocation of the Gallants Channel Bridge and the U.S. 70 Corridor. The state grant was ' matched with $14,454.00 in local funds. This analysis will include analysis of both primary and secondary areas of impact. At the request of the Town of Beaufort, the secondary impact area was expanded to include all of the potential route for the relocation of NC 101. This relocation may occur as the result of the extension of runway 8-26 at the Beaufort Airport. The following summarizes the goals for the study: ' — Identify the appropriate structure for effective citizen participation. ' — Provide a specific forecast of land use and demographic growth and development in both the primary and secondary impact areas. ' — Identify existing land use composition. — Provide mapping of significant land use factors (i.e., soils, floodplain, etc.). ' - Develop specific land use and zoning plans for the primaryand secondary areas. ' — Identify land use concepts which should be implemented within the study area. — Identify infrastructure improvements (water, sewer, drainage, etc.) which must be accomplished to accommodate growth within primary and secondary impact areas. i— Identify changes which should be made to the Town of Beaufort zoning ordinance as a result of development of the primary and secondary impact ' areas. Identify changes which should be made to the Town of Beaufort CAMA ' Land Use Plan, as a result of the new U.S. 70 corridor and relocated NC 101. — Identify opportunities for locating public parks and recreational facilities ' within both the primary and secondary impact areas. This study will result in a comprehensive analysis of the social, economic, land use, and ' environmental impacts resulting from the relocation of the Gallants Channel Bridge, U.S. 70 corridor, and NC 101. 1 II. HIGHWAY CORRIDOR LOCATIONS Map 1 delineates the routes for the relocation of U.S. 70 and NC 101. These locations have been proposed in feasibility studies conducted by the North Carolina Department of Transportation. The North Carolina Department of Transportation has provided the following project ' description: "The 'recommended improvement would consist of a four lane high rise ' structure to replace the existing Gallants Channel Bridge. The remaining roadway is recommended to be four lanes divided (at grade intersections ' where needed) on new location (see Map 1). Right of way should be adequate to contain the roadway and structure and should have limited control of access to prevent strip commercial development. ' Sidewalks should be provided across the bridge and possibly along Turner Street. Before final design, possible bicycle routes should be investigated ' by the town and NCDOT. A flyover type approach should be provided onto Turner Street from the ' western approach and a flyover or ramp provided to allow access from Turner Street east onto the proposed roadway. Traffic coming in from the east will not have access to Turner Street. Intersections which should have t access are Beaufort Road (realigned to provide a crossing). A new frontage road should be constructed to allow access to the industry located at the western end of Beaufort Road. An at grade intersection with NC 101 should ' also be provided. No other existing routes should have access at this time. Limited control of access along the proposed route would check unrestricted commercial and residential development by not allowing direct access. Controlled development would assure that the facility will continue to ' provide adequate travel service throughout the design period." The relocation of NC 101 will be triggered by the extension of the Beaufort Airport runway ' 8-26. The environmental impact analysis for the runway extension has not been prepared. Thus, relocation of NC 101 is not included in the 1995-2001 Transportation Improvement , Program. Ill. TRAFFIC VOLUMES In 1993, approximately 20,700 vehicles per day (vpd) crossed the draw bridge at Gallants ' Channel. Traffic is estimated to reach 40,000 vpd by the year 2010. 1 1 t1Yt IF/M PRIMARY IMPACT AREA SECONDARY IMPACT AREA NEW ROAD CORRIDORS MAP 1 U.S. 70 PRIMARY AND SECONDARY IMPACT AREAS 3 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 IV. PRIMARY AND SECONDARY IMPACT AREAS The primary and secondary impact areas are delineated on Map 1. The primary impact area includes: — A 600 foot wide corridor located along the U.S. 70 corridor. — An expanded area of 1,000 feet around the major intersections of old and new U.S. 70, new NC 101 and U.S. 70 connector, U.S. 70 connector and old U.S. 70, new U.S. 70 and relocated NC 101, and intersection of old and new NC 101. — All of the area within the triangle formed by the new NC 101, new U.S. 70, and U.S. 70 connector. The primary impact area includes approximately 290 acres. It is understood that this area may increase/decrease in size depending upon property line configurations and other factors. The secondary impact area includes approximately 1,351 acres. This area includes: — The Turner Street corridor north of Cedar Street (existing U.S. 70) because Turner Street provides an east flow connector to the new U.S. 70. - All of the Beaufort Airport because of the impact of an extended runway 8- 26 on the area. — Generally, all properties or portions of properties which are adjacent to the new highway corridors. -- Areas which may be altered by the highway relocations, i.e., decreased traffic on the existing U.S. 70 north of Beaufort to its intersection with the new U.S. 70. V. EXISTING LAND USE The existing land use is depicted on Map 2 and summarized on Table 1. The majority of the land in both the primary and secondary impact areas, over 56%, is vacant. The largest usage is transportation/utilities. This is because of the location of the airport in the secondary impact area. The second largest developed category is residential. In the combined primary and secondary areas, approximately 12.3% of the areas are committed to single family, multi -family, and mobile home residential usage. It is significant that the relocated highway corridors are primarily located on vacant land. This provides the town with an opportunity to control how and where growth will occur. 4 JDARY AREAS 5 Table 1 U.S. 70 Corridor Study Primary and Secondary Impact Areas ' Existing Land Use* ' Primary Secondary Land Use Category Impact Area Impact Area Total ' Acreage % Acreage % Acreage % Single -Family 27.8 9.6 110.7 8.1 138.5 8.4 Duplex/Multi-Family 9.5 3.3 16.6 1.2 26.1 1.6 Mobile Home 11.9 4.1 ; 22.8 1.8 34.7- 2.3 ' Commercial Institutional 4.9 1.7 45.1 3.3 50.0 3.0 3.1 1.1 30.7 2.3 33.8 2.2 ' Transportation/ Utilities 5.9 2.0 364.3 27.0 370.2 22.6 Publictinstitutional 4.3 1.5 31.6 2.3 35.9 2.2 ' Open Space 0.8 0.3 15.7 1.2 16.5 1.0 Vacant 221.8 76.4 713.5 52.8 935.3 56.7 ' TOTAL 290.0 100 1,351.0 100 1,641.0 100 ' * Approximate acreages, not based on survey by licensed surveyors. Source: Holland Consulting Planners, Inc. L VI. FLOODPLAIN Except for the Beaufort Airport, only limited areas of the primary and secondary impact areas are located within a 100 year floodplain. The largest developed area within the 100 year floodplain is in the primary impact area south of the airport along West Beaufort Road. Thus, floodplain areas will not be a limiting factor for development within the primary and secondary impact areas. The 100 year floodplain areas are delineated on Map 3. VII. SOILS Map 4 delineates the soils which are located within the primary and secondary impact areas. Table 2 provides a summary of the soil conditions. Almost all of the soils within the primary and secondary impact areas exhibit severe wetness conditions for construction. There are only limited prime farmland soils (AaA and StA) located within the impact areas. Most of the prime farmland soils are located in areas which have already been developed. As development occurs within the primary and secondary areas, the provision of adequate drainage will be a major issue. VIII. UTILITIES Map 5 delineates the portions of the primary and secondary impact areas which are served by central water and sewer. All sewer lines are 8" or larger. The majority of the waterlines are 6" or larger. The following areas have 2-inch waterlines: Crescent Drive, Jill Road, Camp en Road, and a portion of Bunches Road. The line sizes and exact locations may be determined through the Town of Beaufort Public Works Director. IX. POPULATION There are approximately 67 dwelling units located within the primary impact area and 304 within the secondary impact area. Based on the 1990 average household size of 3.3 and a vacancy rate of 10%, the existing total population in the primary and secondary impact areas would be 198 and 900, respectively. The combined existing population is approximately 1,098. This population is disbursed throughout the primary and secondary impact areas. 7 "a "a'oratlon al Ihb mop was 1lnanead In port IMouga grant prorlded by the Norlh CarcHno Co..: MonoQQement Proyqrom, through lands Prorlded by the Coadd Zone Management Ad of 972 as amended. wMch Is adm4iafered by the Office of Ocean and Coastal Resource Me wont, National Oceanic and Atmospheric AdmhdslrallarL INSERT MAP LEGEND -••••-••..

The impact areas include: Developed, Urban Transition, Limited Transition, Rural with Services, and Conservation. The following defines these land classifications: Developed: Areas included in the developed land classification are currently urban in character, with no or minimal undeveloped land remaining. Municipal types of services are in place or are expected to be provided within the next five to ten years. Land uses include residential, commercial, industrial, and other urban land uses at high or moderate densities. With the exception of R-5 Cluster Development, residential densities are allowed in excess of an average of three dwelling units per acre, with a minimum lot size of one acre and a minimum single-family residential lot size of 5,000 square feet. Cluster developments shall not exceed eight units per acre, with a minimum lot size of one acre. Urban Transition: Areas included in the urban transition classification are presently being developed for urban purposes, or will be developed in the next five to ten years. These areas should eventually require complete urban services within the planning period. The urban transition areas include mixed land uses such as residential, commercial, institutional, industrial, and other uses approaching high to moderate densities. Residential densities are allowed in excess of an average of three dwelling units per acre, with a minimum single-family residential lot size of 10,000 square feet. 13 ' LEGEND DEV DEVELOPED ' URBAN TRAN URBAN TRANSITION LIMITED TRAN LIMITED TRANSITION ' RURAL WITH SERVICES RURAL WITH SERVICES CON CONSERVATION ' CITY LIMIT BOUNDARY -••• --•• •- NpP� J EXTRA -TERRITORIAL BOUNDARY CON i 1 The preparation of this map was financed in \ �� part through a grant provided by the North Carolina Coastal Management Program.

Some municipal type services will be required. The limited transition classification is intended for ' predominantly residential use. However, some commercial, office, and institutional uses may be allowed. Residential densities at an average of three units per acre or less are acceptable. Densities within some areas of the limited transition classification may be ' higher. The minimum lot size shall be 10,000 square feet. Clustering or development associated with planned unit developments are acceptable in this classification. ' Rural With Services: Areas included within the rural with services classification are developed at low density. Land uses include residential use where limited water services are provided in order to avert existing or projected health problems. Lot sizes will be large ' and the provision of services will not disrupt the primary rural character of the landscape. The provision of services should not be designed to serve as a catalyst for development. ' Conservation: The following areas of environmental concern are included in the conservation classification: Coastal Wetlands: This classification includes all areas of coastal wetlands which ' include any salt marsh or other marsh subject to regular or occasional flooding by tides, including wind tides. However, tidal flooding is understood not to include hurricane or tropical storm tides. Uses will be allowed within the coastal wetlands ' areas that are consistent with the 15A NCAC 7H use standards. In addition, the town supports possible expansion of the Michael J. Smith Airport into coastal wetlands areas. ' Estuarine Shorelines: All areas lying 0-75 feet landward of the mean high water level of estuarine waters not designated as Outstanding Resource Waters are ' classified as estuarine shorelines. Because of map size and scale, these areas cannot be accurately mapped. Precise locations must be determined in the field. Uses will be allowed within the estuarine shoreline areas that are consistent with ' the 15A NCAC 7H use standards. Estuarine and Public Trust Waters: All public trust areas and estuarine waters are ' included in this classification. All waters of Carteret County are classified as estuarine waters as described by 15A NCAC 7H.0206 or public trust areas as described by 15A NCAC 7H.0207. With the exception of floating structures, uses ' consistent with 15A NCAC 7H.0207 will be allowed. The town opposes the permanent location of floating structures in estuarine and public trust waters ,and in marinas. Except for floating structures policies, the Conservation policies are not ' more restrictive than the use standards included in 15A NCAC 7H. The Developed and Rural with Services are the two largest classifications. There are no conservation areas located within the primary and secondary impact areas except for the ' limited areas alongTown Creek and the Newport River Shoreline. p t 15 XII. EXISTING ZONING The existing Town of Beaufort Zoning Ordinance has 14 separate zoning districts. Of this total, five are residential; five are commercial; two are industrial; and one is open space. ' There is no historic district. Six of the zoning districts are located within the primary and secondary impact areas. t These include: ' R-20 - Single family Residential R-15 Single-family Residential , R-8 Multi -family Medium Density Residential B-1 General Business B-3 Marina Business ' I-W Industrial Warehouse Most of the primary and secondary areas are zoned in a residential classification. The ' majority of the residential property is zoned R-20. Business zoning, primarily B-1, is scattered along NC 101, U.S. 70, and the west end of West Beaufort Road. An area of ' B-3 zoning is located between the airport and Town Creek. The zoning patterns are depicted on Map 7. ' The following provides summary descriptions of these zoning districts: ' R-8 Multi -family Residential Purpose. ' The R-8 Multi -family Residential District is established as a medium to high 9 density district in which the principle use of the land is for single-family, two-family, and multi -family residences.

Introduction As indicated in the discussion of existing land use, the majority of the land within the primary and secondary impact areas is vacant. Thus, as the new highway corridors are constructed, the Town of Beaufort will have an opportunity to adequately plan for and control the quality of development in these areas. Failure to implement sound planning will result in inefficient land use and the improper allocation of both fiscal and physical resources. B. Highway Corridor Classifications The function of highway corridors strongly influence the types of land use which occur adjacent to them. These corridors often create "spines" of high intensity land use located on either side of the adjacent highway. Scattered along these corridors are focus areas which normally contain an area's highest intensity land uses. These focus areas are usually located at the intersections of highway corridors. Normally focus areas should be located one mile or more apart. There are eight new intersections which will exist as a result of the construction of the new highway corridors. Highway corridors are hierarchial. They may be classified as one of the three following types: Major Thoroughfares: These include freeways (limited access roads which primarily carry through traffic) and "other" major thoroughfares (high traffic volume roadways which cant' both local and through traffic). The new U.S. 70, new NC 101, and NC 101/U.S. 70 connector should be considered major thoroughfares. Minor Thoroughfares: These roads primarily carry local traffic and typically serve residential land uses. Collector Streets: These streets are intermediate size streets designed to provide appropriate connections between the thoroughfare system and the remainder of the local street system. Collector streets should be constructed both within and between subdivisions (both residential and nonresidential). Collector streets facilitate more efficient movement within an area. The collector street system should develop as land is subdivided. An integrated collector system will enable the town to avoid "dumping" all traffic from residential and commercial areas onto adjacent thoroughfares. 23 ' C. Highway Corridor Transition Areas ' Highway Corridor Transition Areas lie along thoroughfares between focus areas. These focus areas are desirable locations for commerce, and will become increasingly important to the development of the primary and secondary impact areas as development fills in the ' network of roadways. Commercial or retail centers should be encouraged to located within the focus areas. They should be distinct from surrounding lower intensity areas. These ' transition areas adjoin transportation corridors. The land uses located within transition areas should be significantly less intense than those in the focus areas. Transition areas ' should serve to buffer the activity on the roadway from adjacent residential areas. Land uses in the corridor transition areas should vary according to the function of the roadway. Vegetation, screening, lower building densities, and a general "green" appearance should characterize these areas. Landscaping, sign control, lighting, curb cuts, and buffering should be emphasized and carefully regulated in transition areas. ' Land uses in transition areas along nonresidential corridors should primarily consist of low intensity office and institutional uses and medium to high density residential uses. Low ' density residential uses and retail uses should not be encouraged. ' Land uses in transition areas along residential corridors should be primarily residential in nature with medium intensity residential preferred. Low density residential is also desirable if individual lot access onto the thoroughfare is restricted. Low density office uses may ' also be appropriate in some situations. ' It is important to remember that NC 101 and U.S. 70 serve as "gateways" to the Beaufort area. Thus, these highway corridors should be carefully designed and developed to reflect their importance as entranceways to Beaufort's planning jurisdiction. When adjacent land ' is subdivided/developed, the town should consider requiring that additional yard set backs be required to allow for future road widening. Curb cuts should be strictly controlled to ' facilitate smooth traffic flow. A uniform landscaping plan should be developed. Canopy trees should be utilized whenever feasible. Attractive, uniform signage should be required. D. Corridor Design Actions ' The following design actions should be considered by the Town of Beaufort to protect the traffic carrying capacity of the roadways and to protect properties adjacent to the corridors: 24 -- Review driveway regulations so that requirements are based on street classification and street frontage. Very few curb cuts should be permitted along the new thoroughfares. -- As land subdivision progresses, develop a collector street plan. Ensure adequate road connections between existing and future residential development; development should have more than one entrance/egress. -- Include sidewalks and widened outside curb lanes as part of design and construction of new publicly -funded thoroughfares. -- Encourage the development of joint or shared driveways. -- Place utilities underground when thoroughfares are constructed or widened. — Discourage strip commercialization. — Encourage/require parking lot connections between commercial development. Limit the development of focus areas. All new intersections can not become high intensity focus areas. If all new intersections are permitted to develop as major focus areas, the entire U.S. 70 and NC 101 corridors will "in -fill' and the result will be continuous strip commercialization. In the deliberations of rezoning requests, the Beaufort Board of Adjustment and Board of Commissioners should carefully consider the following: -- All uses which are allowed in a zoning district must be considered. A decision to rezone or not to rezone a parcel or parcels of property cannot be based on consideration of only one use or a partial list of the uses allowed within a zoning district. -- Zoning decisions will not be based on aesthetic considerations. Requests for zoning changes will not be approved if the requested change will result in spot zoning. Spot zoning is a form of discriminatory zoning whose sole purpose is to serve the private interests of one or more landowners instead of furthering the welfare of the entire community as part of an overall zoning plan. Although changing the zoning classification of any parcel of land to permit a more intensive use could possibly constitute spot zoning, the test lies in its relationship to the existing zoning pattern and guidelines of the local comprehensive plan. Spot zoning is based on the arbitrary and inappropriate nature of a rezoning change rather than, as is commonly believed, in the size of the area being rezoned. -- Zoning which will result in strip development will be discouraged. Strip development is a melange of development, usually commercial, extending along both sides of a major street. Strip development is often a mixture of 25 ' auto -oriented enterprises (e.g., gas stations, motels, and food stands), truck -dependent wholesaling and light industrial enterprises along with the once -rural homes and farms that await conversion to commercial use. Strip ' development may severely reduce traffic -carrying capacity of abutting streets. ' -- The concept of uniformity will be supported in all zoning deliberations. Uniformity is a basic premise of zoning which holds that all land in similar circumstances should be zoned alike; any different treatment must be justified by showing different circumstances. -- Zoning regulations will be made in accordance with the Town of Beaufort ' Comprehensive Plan and Gallants Channel Bridge/U.S. 70 Transportation Corridor Study and Impact Analysis. These regulations shall be designed to lessen congestion in the streets; to secure safety from fire, panic, and ' other dangers; to promote health and the general welfare; to provide adequate light and air; to prevent the overcrowding of land; to avoid undue concentration of population; and to facilitate the adequate provision of transportation, water, sewerage, schools, parks, and other public ' requirements. The regulations shall be made with reasonable consideration, among other things, as to the character of the district and its peculiar suitability for particular uses, and with a view to conserving the ' value of buildings and encouraging the most appropriate use of land throughout the Town of Beaufort planning jurisdiction. -- Specifically, the Board of Adjustment and Board of Commissioners should ask the following questions: ' -- Does the town need more land in the zone class requested? Is there other property in the community that might be more ' appropriate for this use? -- Is the request in accordance with the town plan? i-- Will the request have a serious impact on traffic circulation, parking space, sewer and water services, and other utilities? -- Is there a good possibility that the request, as proposed, will result in lessening the enjoyment or use of adjacent properties? — Will the request, as proposed, cause serious noise, odors, light, activity, or unusual disturbances? ' — Does the request raise serious legal questions such as spot zoning, hardship, violation of precedents, or need for this type of use? W E. Land Use Plan Map 8 delineates the recommended future land use for both the primary and secondary impact areas. The land use patterns are color coded as an 'overlay" on the existing land , use patterns for comparison. Table 5 summarizes the vacant and developed acreages within each land use category. Table 5 U.S. 70 Corridor Study Primary and Secondary Impact Areas Future Land Use Acreage* Category Developed Vacant Total ' Residential Corridor 31.3 67.9 99.2 Medium to High Density Residential 153.7 95.6 249.3 ' Low Density Residential 98.5 321.3 419.8 Nonresidential Corridor Area 18.9 129.5 148.4 ' Commercial High.

The airport/utilities category assumes that approximately 9.5% of the vacant land within the primary and secondary impact areas will be developed as right-of-way to serve the developed property. This is approximately the percentage of land committed to right-of- way usage with the existing primary nd secondary areas (excluding airport and utilities usage). Table 5 includes the category existing commercial sustained. This category identifies commercial land uses which will remain along the existing U.S. 70 highway corridor, the vicinity of the West Beaufort Road/Tumer Street intersection and the north side of Cedar Street west of the Craven Street/Cedar Street intersection. While commercial areas exemplify some of the worst aspects of strip commercialization, it would be very difficult, if not impossible, to eliminate them. Thus, the plan accepts their continuation. However, these commercial areas should be contained and not allowed to further intrude on adjacent residential areas or spread along highway corridors. The existing commercial area located along the U.S. 70 highway corridor may be considered an extension of the commercial 27 LEGEND ' SINGLE FAMILY RESIDENTIAL TRANSPORTATION 8 UTILITIES ��..

The high intensity focus areas which are recommended for the intersections of the NC 101/U.S. 70 connector and new NC 101 and old U.S. 70 are only one-half to one -quarter ' of a mile apart. Great care must be taken to ensure that commercial in -fill or strip commercialization does not occur along the NC 101 connector. If this is permitted to ' happen, congestion at the new U.S. 70/NC 101/U.S 70 connector road will occur. The primary purpose of this plan is to protect the traffic carrying capacity of both the new NC 101 and new U.S. 70 highway corridors. Nonresidential corridor areas are indicated along: -- The NC 101/U.S. 70 connector road including and area extending north to an existing commercial area. ' — The east/northeast side of the new NC 101 from its intersection with the old NC 101 to the high intensity focus area located at the new NC ' 101/connector road intersection. — Along both sides of existing NC 101 corridor north of the airport. -- South of the high intensity focus area located at the new NC 101/connector road intersection and within most of the triangular area bounded by new NC ' 101, new U.S. 70, and the connector road. — Southeast of the existing commercially zoned property located along the 1 existing U.S. 70 corridor. These nonresidential corridor areas are important for the protection of adjacent residential ' areas. This is especially true along the existing and new NC 101 corridors where these "buffers" will serve to separate residential areas from industrial development proposed for ' location east/northeast of the airport. In addition, a commitment to develop these areas as nonresidential corridors will maintain low density non-commercial development which will be less disruptive to efficient traffic flow. 1 Industrial development is indicated for most of the area east/northeast of the airport and ' between the existing and new NC 101 corridors. This area should be limited to light industrial usage which is compatible with safe aircraft operations. Location of this industrial ' area in between the existing and new NC 101 highway corridors affords excellent transportation accessibility. Most of the existing residentially zoned property which is located east of the airport along the existing NC 101 and south/southeast of the airport 29 along West Beaufort Road is recommended for medium to high density residential. This area includes some commercially zoned properties which are dispersed along the existing NC 101. These areas should be phased out if the existing commercial uses are discontinued. Further commercialization along NC 101 should not be permitted. In addition, caution should be taken to protect existing high density residential areas along Turner Street and between Turner and Craven Streets. With Turner Street serving as an east flow connector to the new U.S. 70 corridor, there may be some pressure for conversion to commercial usage. The primarily undeveloped areas located west of the existing NC 101 nonresidential corridor and north/northeast of the new NC 101 nonresidential corridor are committed to low density residential usage. These areas should be developed with subdivisions containing interconnected street systems which will allow for the development of a collector street system. A residential corridor area is recommended for the areas along both the existing and new U.S. 70 corridor areas north of the existing U.S. 70/connector road intersection and the connector road nonresidential corridor area. In addition, a small residential corridor area is recommended along vacant property located on the west side of the existing U.S. 70 highway immediately south of the existing U.S. 70/connector road high intensity focus area. A generalized area is indicated for expansion of the airport and establishment of anew runway protection zone (RPZ) which is the trapezoidal shaped area at the end of the extended runway. This airport expansion is necessary to accommodate the extension of runway 8-26. The area of airport expansion is estimated. The environmental assessment for the runway extension and final plans and drawings have not been completed. Therefore, the actual area of acquisition may vary some from that which is indicated. The RPZ is shown as an acquired area. While fee simple acquisition of the RPZ is not required, it is recommended by the Federal Aviation Administration (FAA). Even if the RPZ is not acquired fee simple, the height of structures within the area should be controlled with avigation easements. The reader is cautioned that the areas delineated for each land use category should be utilized as a guideline. The exact boundaries will vary some as land is subdivided. The exact land use boundaries will fall along new and/or existing parcel boundary lines. However, care should be taken to adhere to the recommended boundaries as closely as possible. 30 i ' F. Parks and Recreation Recreational facilities maintained by the Town of Beaufort include: Waterfront Park; ' Grayden Paul Park; the Taylor's Creek Town Dock; Randolph Johnston Park; and a park at the end of Front Street, which includes tennis courts and a boat launch. Other ' recreational facilities located within the town's planning jurisdiction include Freedom Park and Beaufort Elementary School recreational area. The North Carolina Division of Parks maintains recreation facilities standards. The following table, taken from the 1995 Town of Beaufort Land Use Plan, provides a ' comparison of town maintained facilities and the states standards.

Source: 1995 Town of Beaufort Land Use Plan. ' Based on the comparison provided in Table 6, the Town of Beaufort meets or exceeds the state recreation standards except for swimming pools and neighborhood centers. Because of the outdoor water activities which exist in Carteret County, it should not be necessary for Beaufort to provide swimming pools. 31 The Town of Beaufort land use plan also indicates that by the year 2005, the town's population is expected to reach 4,600. This figure represents an increase of approximately 600 permanent residents since 1994. Based on the state's standards, the population increase that has been forecast does not create any additional demand for recreational facilities prior to the year 2005. However, once the Gallants Channel Bridge/U.S. 70 relocation project is completed, changes in the geographic location of development will occur. As a result, the Town of Beaufort may gain interest in annexing portions of the primary and secondary impact areas. If Beaufort's town limits are extended into the primary and secondary impact areas, an imbalance in the location of the town's recreational facilities will occur. Therefore, in order to accommodate future annexations and the possibility that population growth may exceed that which has been forecast, additional recreational areas should be considered. One specific site to be considered for parks and recreational use is located in the primary impact area where a "triangle" is formed by the proposed U.S. 70, NC 101, and U.S. 70/NC 101 connector. Other areas may also be desirable for future parks and recreational use. Generally, areas where coastal and 404 wetlands are present provide good opportunities for the provision of open space because these areas are not suitable for development. One popular way of providing open space areas is through the use of greeways. The following provides a general definition of a greenway: A greenway is a continuous strip of vegetated land protected for special uses, extending through an urban area or area targeted for future development. Various segments of a greenway should perform one or more of the following functions: beautify the city, preserve open space, maintain wildlife habitat, provide paved foot trails/bikeways, manage floodplains and stormwater, control sedimentation, provide a park -like environment, provide access to surface drainage systems and service distribution lines, reduce air pollution, absorb noise, and cool the urban atmosphere. In the event that the Gallants Channel Bridge/U.S. 70 Relocation project becomes a reality, the Town of Beaufort will further investigate the possibilities and opportunities of providing additional recreational facilities within the impact areas. 32 I G. Zoning ' As described in the existing conditions section of this study, the Town of Beaufort Zoning Ordinance includes 14 zoning districts. Not all of these districts should be allowed within the primary and secondary impact areas. In addition, the existing Town of Beaufort Zoning Ordinance does not include some zoning provisions/regulations which would be vital to implementing the recommended land use patterns. The land use ' categories should include the following existing and proposed zoning districts: LOW DENSITY RESIDENTIAL ' — R-20 Single-family Residential — R-15 Single-family Residential — Medium to High Density Residential — R-5 Residential Cluster Development — R-10 Single-family Residential and Mobile Home/Travel Trailer Park District — R-8 Multi -family Medium Density Residential District ' RESIDENTIAL CORRIDOR AREA — R-15 Single-family Residential District - 0-1 Office and Institutional (proposed) ' NONRESIDENTIAL CORRIDOR AREA — R-5 Residential Cluster Development — R-8 Multi -family Medium Density Residential District ' — R-10 Single-family Residential and Mobile Home/Travel Trailer Park District — 0-1 Office and Institutional (proposed) ' COMMERCIAL HIGH INTENSITY FOCUS AREA Business Planned Building Group (proposed) — B-I General Business District (with minimum lot sizes and yard requirements provided) ' — B-3 Waterfront Commercial (with minimum lot sizes and yard requirements provided) — 0-1 Office and Institutional (proposed) INDUSTRIAL — L-I Light Industrial — Industrial Park Regulations (with multi -family dwellings eliminated as a special use) (Proposed) Some of the existing zoning ordinance regulations may remain intact. However, in order ' to accomplish the recommended land use plan, revisions to the existing regulations and the addition of some new zoning provisions will be necessary. 33 H. Zoning Revisions 1. General Zoning Ordinance Revisions With or without the construction of the new U.S. 70 and NC 101 highway corridors, the Town of Beaufort zoning ordinance needs to be rewritten. The following provides a general summary of the changes which should occur. — Provide a definitions section. I — The number of existing zoning districts should be reduced and consolidated I especially the residential and commercial districts. — The zoning ordinance should be updated to be consistent with current North ' Carolina General Statutes including but not limited to: vested rights, incorporated area/extraterritorial area, Board of Adjustment representation, notification of property owners of pending rezoning actions, historic , preservation regulations, zoning and ABC permit regulations, etc. Significant changes have occurred within the past four years which may not be reflected in the town's current zoning ordinance. — Minimum lot sizes and yard area and height requirements should be ' 9 provided for all nonresidential zones. — Parking lot standards should be revised to allow alternatives to impervious ' paving to reduce runoff. — Landscaping requirements should be provided. ' — Revise the mobile home and travel trailer park regulations. ' — All performance standards such as parking and signage should be reviewed. , — Provide a table of permitted uses which will consolidate all uses by district on one consolidated section. This will make the zoning ordinance easier to ' use and understand. In addition, the following regulations should be added to aid in the regulation of development within the town's ETJ: — Establish commercial, office and institutional, and multi -family planned , building group regulations. Planned building group regulations will provide specific performance standards for the construction of multiple buildings ' and/or multiple uses on a single parcel of property. 34 � Establish an office and institutional zoning district. Establish an industrial park zoning district. Establish airport height restriction zoning. Eliminate residential uses as a special use in the B-1, General Business District. Reduce the number of uses permitted in the General Business District (B-1). Uses which will/may be objectionable to residential uses should be eliminated. These may include, but not necessarily be limited to: automobile repair and paint shops, bus terminals, building supply or equipment sales, fabricating shops, mobile home park or travel trailer park, tire recapping and retreading, and wholesale and warehouse establishments. These uses may be deleted or moved to the B-2 Highway Business district or an industrial district. Consolidate the WC Waterfront Commercial and B-3 Marina Business Districts. Specific Zoning Ordinance Revisions a. Office and Institutional Zoning The Town of Beaufort should have a more comprehensive Office and Institutional Zoning District. This district would provide for an orderly transition from the highway corridor areas to adjacent low density residential areas. Office and Institutional zoning would be utilized in the residential corridor, nonresidential corridor, and commercial high intensity focus areas. In the high intensity focus areas, 0-1 zoning should be utilized only as a transitional buffer to provide some protection for adjacent residential areas. The following describes the structure of the 0-1 zoning district: Definition: The 0-1 zoning district is defined as certain land areas with structures that provide office space for professional services, institutional functions, and normally medium to high density residential accommodations. The district is normally small and limited to transition areas between major highway corridors, high density commercial areas, and adjacent low to medium density residential areas. The district's zoning regulations are designed to permit development of the permitted functions and still protect and be compatible with nearby residential districts. 35 PERMITTED AND SPECIAL USES Use Permitted Use Special Use Accessory Building x Accessory Uses (incidental to permitted use) x Advertising Agency x Animal Medical Care x Assembly Hall x Art Gallery x Artists, Commercial x Associations or organizations; civic, social, and fraternal x Automobile off-street parking (commercial lots) x Bank, Savings and Loan, and Other Financial Activities x Barber or Beauty College Instruction x Barbering or Beauty Salons x Cemetery x Chiropractor x Church x Clinic Services, Medical and Dental x Club or Lodge x Contractors (including outside storage of materials, supplies, or equipment) x Copy and duplicating services x Credit Agencies x Cultural Arts Center (including theaters, offices, classrooms, etc.) x Dance Studios and Schools x Day Care Center (including Kindergarten) S Day Care Facilities (adult and child) x Dentist and Dental Laboratories x Dwelling, Single-family x Dwelling, Two-family x Dwelling, Multiple family (includes condominiums and attached units for individual ownership) S Employment Agencies x Employee Services (not available to general public) x Engineering; Architectural and Survey Offices x Family Care Home x Fill (earth elevation) x 36 1 Use Permitted Use Special Use Fire Station Operations X Funeral Home X Golf Course (public or private) X Health Services, doctor's offices and clinics X Home for the Aged X Home Occupations X Hospitals (excluding hospital) X Insurance Agencies X Interior Design or Decorator Shop X Labor Unions X Laboratory Operations, medical or dental X Law Offices X Library X Manufactured Building Home (individual for office and exhibition) X Motels and Hotels X Nursing and Personal Care Facility X Offices not elsewhere classified (with no on -premises stock of goods for sale to the general public) X Parks and Recreation areas (non-commercial public) X Personal Services not elsewhere classified X Photography Studios X Post Office X Private Recreation Club or Swimming Club (activities not operated as a business for profit) X Printing and Reproduction .

Commercial Planned Building Group Requirements Commercial Planned Building Group requirements should be incorporated into the Town of Beaufort zoning ordinance to regulate the development of multiple commercial building uses on a single parcel or when construction involves a building of or greater than 7,000 square feet. This will provide the town control for shopping center development and significantly assist in the prohibition of strip commercialization. In addition, planned building group regulations will aid in regulating: points of ingress and egress, signage location, on -site traffic circulation, vegetation, building orientation, buffering adjacent to or near residential areas and lighting. The commercial planned building group requirements should apply in the O-I, B-1, and B-3 zoning districts. The following summarizes the recommended commercial planned building group regulations: Screening and fencing: A screen not less than six (6) feet high of dense plant material and/or fence where the lot abuts a residential lot. Lots fronting on a public street: The planning board may approve plans with lots located in the interior of a business planned building group project provided that the board finds that adequate access is assured by the design of the planned building group.

Industrial Park Zoning Much of the property proposed for industrial usage is located within close proximity to residential property. Thus, to ensure compatible development and prohibit the development of conflicting land uses, industrial park zoning will impose stricter development standards than are proposed for other industrial areas within the town's planning jurisdiction. The following provides a description of the proposed industrial park district: Definition: This district is defined as certain lands more suited for industrial uses than other land uses as a result of proximity to major utility lines and transportation arteries, but situated where residential or office -institutional development is, or may be, in close proximity to one or more sides of the district. The purpose of this district is to permit selected quality industries in a planned physical setting for manufacturing establishments.

The reduction shall be limited to a maximum credit of two (2) percent or four (4) regulated trees retained. Where screening is required under Section 7 to separate a parking facility from an area which is in a different zoning district, the requirements of Section 7 or those of this section, whichever are more stringent, shall apply. When a parking facility is within 50 feet of the public right-of-way a perimeter planted strip shall be installed, consisting of a low buffer incorporated into the streetyard. The Director may waive all or part of the requirements of this section for any facility which is limited to periodic or intermittent use for vehicular parking, such as parking lots for churches or recreational facilities, provided the facility is completely covered by grass or otherwise presents a landscaped effect. The Director may waive the requirements of this section for temporary parking lots when he finds that a waiver is necessary to relieve hardship and will not violate the purposes of this section. Any such waiver shall not exceed one year. 7. Bufferyards Purpose. A screening buffer is intended to protect adjacent residential areas from excessive heat, dust and winds; illumination from car headlights, elevated yard lights, building lighting and electric signs; noise from mechanical equipment clusters, vehicular traffic and concentrations of people; fumes and odors from automobile exhaust emissions and other such characteristics of intensive and extensive development. The screening buffer shall provide necessary visual and acoustical privacy so that home life may be conducted in an undisturbed and unthreatened residential environment and shall provide for the protection and preservation of property values for the adjoining property. I Screening buffer standards: t Bufferyard required. In the B-1, B-2, B-3, L-1, 1-W, and IP districts when a new principal structure is built, and/or an existing principal structure is renovated or expanded sufficiently to increase its physical gross floor area by fifty (50) percent or more as determined by the ' code enforcement officer, in any one or more expansions, a screening buffer must be provided along all side and rear property lines abutting a residential district or use. Types of screening. The following standards shall be applied to provide the highest ' protection for affected property. The highest side of any two properties at their common property line shall be used in determining the minimum height of a screening buffer. The degree of effectiveness for opacity shall be judged from the residential property being ' screened. ' (A) Planted (living) Screening. The minimum height of trees used in a planted screen shall be eight feet in initial planting and fifteen feet at maturity; the minimum height of evergreen shrubs used in a planted screen shall be thirty-six (36) inches at initial ' planting and six feet at maturity. These requirements are illustrated in the following diagram: n BUFFERYARD HEIGHT REQUIREMENTS TRESS 8' MININIUM INSTALLED HEIGHT 15' MINIMUM MATURE HEIGHT WING I 4ERS EVERGREEN SHRUGS 360 MINIMUM INSTALLED HEIGH T 6' MINIMUM MATURE HEIGi .? 69 (B) When more than one row of planting is required by this section, such planting shall be arranged in an alternating fashion to form a continuous opaque screen. If approved by the Director, regulated trees as defined in Section 4 within the required bufferyard may be included in computing the required bufferyard plantings. Berms may also be used to satisfy the requirements hereunder. The height of the berm and plant material used thereon shall be at least eight feet at maturity. Any plant material used in connection with a berm must meet all minimum height requirements specified above. Screening types: Plants. — Type A. This is a medium density screen intended to block visual contact between uses and to create spatial separation. The bufferyard shall be at least ten feet wide, and shall consist of plant material which at maturity creates a screen which is at least 75% opaque. For every linear one hundred (100) feet, or fraction thereof, the screen shall consist of a combination of at least two (2) canopy type trees planted 40-60 feet on center and ten (10) evergreen shrubs eight (8) feet on center. New trees and shrubs shall be evenly spaced at planting, with trees having an 8-foot minimum installed height, and shrubs having a 36-inch minimum installed height. An example site plan is illustrated below: TYPE A BUFFERYARD AF=CTE] PROPERTYOWNER 100 FEE EVERGREENS: SINGLE ROW.

This is a high density screen intended to exclude all visual contact between uses and to create a spatial separation. The bufferyard shall have a minimum width of fifteen feet, and shall consist of plant material which at ' maturity creates a screen which is 100% opaque. For every linear one hundred (100) feet, or fraction thereof, the screen shall consist of a combination of at least three (3) canopy type trees planted 20-40 feet on ' center and thirty-four (34) evergreen shrubs in a double -staggered row six (6) feet on center. New trees and shrubs shall be evenly spaced at planting, with trees having an 8-foot minimum installed height, and shrubs t having a 36-inch minimum installed height.

Vested Right Provisions In 1990, the North Carolina General Assembly enacted legislation providing vested rights in the zoning process to protect property from subsequent zoning changes for up to three years. The following regulations should be incorporated into the town's zoning ordinance to provide for vested rights procedures. 1. Purpose The purpose of this section is to implement the provisions of G.S. 160A-385.1 pursuant to which a statutory zoning vested right is established upon the approval of a site specific development plan. Neither a variance, a sketch plan nor any other document that fails to describe with reasonable certainty the type and intensity of use for a specified parcel or parcels of property shall constitute a site specific development plan. Establishment of a Zoning Vested Right (a) A zoning vested right shall be deemed established upon the valid approval, or special use approval, by the Board of Commissioners or Board of Adjustment, as applicable, of a site specific development plan, following notice and public hearing. 75 3. (b) The approving authority may approve a site specific development plan upon ' such terms and conditions as may reasonably be necessary to protect the public health, safety, and welfare. (c) Notwithstanding subsections (a) and (b), approval of a site specific development plan with the condition that a variance be obtained shall not , confer a zoning vested right unless and until the necessary variance is obtained. (d) A site specific development plan shall be deemed approved upon the effective date of the approval authority's action or ordinance relating thereto. ' (e) The establishment of a zoning vested right shall not preclude the application of overlay zoning that imposes additional requirements but does not affect the allowable type or intensity of use, or ordinances or regulations that are general in nature and are applicable to all property subject to land -use regulation by the Town of Beaufort, including, but not limited to, building, fire, plumbing, electrical, and mechanical codes. Otherwise applicable new or amended regulations shall become effective with respect to property that is subject to a site specific development plan upon the expiration or termination of the vested right in accordance with this chapter. (f) A zoning vested right is not a personal right, but shall attach to and run with the applicable property. After approval of a site specific development plan, all successors to the original landowner shall be entitled to exercise such right while applicable. Approval Procedures and Approval Authority (a) Except as otherwise provided in this section, an application for site specific development plan approval shall be processed in accordance with the procedures established by ordinance and shall be considered by the designated approval authority for the specific type of zoning permit, special use permit, building permit, or variance approval for which application is made. (b) Notwithstanding the provisions of subsection (a), if the authority to issue a particular zoning or special use, building, or variance permit or approval has been delegated by ordinance to a board, committee or administrative official 76 other than the Town of Beaufort Board of Commissioners, Board of Adjustment, or other planning agency designated to perform any or all of the duties of the Board of Adjustment, in order to obtain a zoning vested right, the applicant must request in writing at the time of application that the application be considered and acted on by the Town of Beaufort Board of Commissioners or Board of Adjustment, following notice and a public hearing as provided in G.S. 160A-364. (c) In order for a zoning vested right to be established upon approval of a site specific development plan, the applicant must indicate at the time of application, on a form to be provided by the Town of Beaufort, that a zoning vested right is being sought. (d) Each map, plat, site plan or other document evidencing a site specific development plan shall contain the following notation: "Approval of this plan establishes a zoning vested right under G.S. 160A-385.1. Unless terminated at an earlier date, the zoning vested right shall be valid until (date)." (e) Following approval or conditional approval of a site specific development plan, nothing in this chapter shall exempt such a plan from subsequent reviews and approvals to ensure compliance with the terms and conditions of the original approval, provided that such reviews and approvals are not inconsistent with the original approval. (f) Nothing in this chapter shall prohibit the revocation of the original approval or other remedies for failure to comply with applicable terms and conditions of the approval or the zoning ordinance. Duration (a) A zoning right that has been vested as provided in this chapter shall remain vested for a period of two years. This vesting shall not be extended by any amendments or modifications to a site specific development plan unless expressly provided by the approval authority at the time the amendment or modification is approved. (b) Upon issuance of a building permit, the expiration provisions of G.S. 160A- 418 and the revocation provisions of G.S. 160A-422 shall apply, except that 77 a building permit shall not expire or be revoked because of the running of I time while a zoning vested right under this section is outstanding. 5. Termination I A zoning right that has been vested as provided in this chapter shall terminate: ' (a) at the end of the applicable vesting period with respect to buildings and uses for which no valid building permit applications have been filed; ' (b) with the written consent of the affected landowner; ' (c) upon findings by the Town of Beaufort Board of Commissioners, by ordinance after notice and a public hearing, that natural or man-made , hazards on or in the immediate vicinity of the property, if uncorrected, would pose a serious threat to the public health, safety, and welfare if the project ' were to proceed as contemplated in the site specific development plan; ' (d) upon payment to the affected landowner of compensation for all costs, expenses, and other losses incurred by the landowner, including, but not limited to, all fees paid in consideration of financing, and all architectural, , planning, marketing, legal, and other consultant's fees incurred after approval by the Town of Beaufort, together with interest thereon at the legal ' rate until paid. Compensation shall not include any diminution in the value of the property which is caused by such action; (e) upon findings by the Town of Beaufort Board of Commissioners, by ordinance after notice and a hearing, that the landowner or his ' representative intentionally supplied inaccurate information ormade material misrepresentations which made a difference in the approval by the approval ' authority of the site specific development plan; or (f) upon the enactment or promulgation of a state or federal law or regulation ' that precludes development as contemplated in the site specific development plan, in which case the approval authority may modify the , affected provisions, upon a finding that the change in state or federal law has a fundamental effect on the plan, by ordinance after notice and a hearing. ' 78 ' 6. Voluntary Annexation A petition for annexation filed with the Town of Beaufort under G.S. 16OA-31 or G.S.160A- 58.1 shall contain a signed statement declaring whether or not any zoning vested right with respect to the properties subject to the petition has been established under G.S. 160A- ' 385.1 or G.S. 153A-344.1. A statement that declares that no zoning vested right has been established under G.S. 160A-385.1 or G.S. 153A-344.1, or the failure to sign a statement ' declaring whether or not a zoning vested right has been established, shall be binding on the landowner and any such zoning vested right shall be terminated. ' 7. Limitations ' Nothing in this chapter is intended or shall be deemed to create any vested right other than those established pursuant to G.S. 160A-385.1. 8. Repealer ' In the event that G.S. 160A-385.1 is repealed, Section 15.0 shall be deemed repealed and the provisions hereof no longer effective. ' K. Airport Zoning ' Airport height restriction zoning should be incorporated into both the Town of Beaufort and Carteret County zoning ordinances. Development of such a regulation must be closely coordinated with the Airport Commission. The regulations must be designed to protect the integrity and safety of the FAA mandated approach and transitional surfaces for the airport. ' Draft airport height control zoning regulations are not provided because such regulations should be provided by the airports planning/engineering consultants who will be familiar with the technical specifications for the airport. L. Nonresidential Zones Minimum Lot Sizes and Yard, Area and Height Requirements The Town of Beaufort zoning ordinance does not provide minimum lot performance standards for nonresidential lots. Except for this C-D district, this deficiency should be ' eliminated. The following lot standards are recommended. 79 Minimum Minimum Minimum Zoning Minimum Minimum Front Side Rear District Lot Size Width Yard Yard* Yard Maximum Height C-D 0 0 0 0 0 B-1 6,000 60 30 5 10 B-2 7,500 65 35 7 15 B-3 7,500 65 35 7 15 L-1 10,000 50 20 35 I-W 10,000 50 20 35 IP 25 acres 50 30 50 35 35 35 35 35 35 See recommended IP regulations * Side yards on the street side of corner lots should be increased one and one-half times. XIV. STORMWATER MANAGEMENT Approximately 56% of the primary and secondary impact areas are vacant. Thus, it is imperative that an effective and enforceable control strategy be developed by the town as soon as possible to provide for the regulation of stormwater runoff. A storm water control ordinance should -- Protect the absorptive, purifying, and retentive functions of natural systems. Provide for post development stormwater runoff characteristics which resemble the conditions that existed before the sites alteration. The following draft stormwater control ordinance is recommended for adoption by the Town of Beaufort: SECTION ONE: SHORT TITLE This ordinance shall be know as the "Stormwater Control Ordinance for Beaufort, NC." SECTION TWO: FINDINGS OF FACTS The Board of Commissioners of the Town of Beaufort finds that uncontrolled drainage development of land has a significant adverse impact upon the health, safety, and welfare of the community. More specifically, :1 (a) Stormwater runoff can cant' pollutants into receiving water bodies, degrading water quality and result in closures of shellfishing waters; ' (b) The increase in nutrients such as phosphorus and nitrogen accelerates eutrophication of receiving waters, adversely affecting flora and fauna; ' (c) Improperly channeling water increases the velocity of runoff, thereby increasing erosion and sedimentation; ' (d) Construction requiring the alteration of natural topography and removal of vegetation tends to cause a loss of natural recharge areas and increase erosion; ' (e) Siltation of water bodies resulting from increased erosion decreases their capacity to hold and transport water, interferes with navigation, and harms flora and fauna; ' (f) Impervious surfaces increase the volume and rate of stormwater runoff and allow less water to percolate into the soil, thereby decreasing groundwater recharge; (g) Improperly managed stormwater runoff can increase the incidence of flooding and the level of floods which occur, endangering property and human life; (h) Improperly managed stormwater runoff can interfere with the maintenance of optimum ' salinity in estuarine areas, thereby disrupting biological productivity; (i) Substantial economic losses result from these adverse impacts on community waters; ' Q) Many future problems can be avoided if land is developed in accordance with sound stormwater runoff management. ' SECTION THREE: OBJECTIVES t In order to protect, maintain, and enhance both the immediate and the long term health, safety, and general welfare of the citizens of the Town of Beaufort, NC, this ordinance has the following objectives: ' (a) To encourage productive and enjoyable harmony between humanity and nature; (b) To protect, restore, and maintain the chemical, physical, and biological integrity of the ' waters of its tributaries. ' (c) To prevent individuals, business organizations, and governments from causing harm to the community by activities which adversely affect water resources; ' (d) To encourage the construction of drainage systems which aesthetically and functionally approximate natural systems; (e) To encourage the protection of natural systems and the use of them in ways which do not impair their beneficial functioning; 1 81 (f) To encourage the use of drainage systems which minimize the consumption of ' electrical energy or petroleum fuels to move water, remove pollutants, or maintain the systems; (g) To minimize the transport'of pollutants to area surface waters; , (h) To maintain or restore groundwater levels; (i) To protect, maintain or restore natural salinity levels in estuarine areas; 0) To minimize erosion and sedimentation; ' (k) To prevent damage to wetlands and to the local natural recharge areas know as interdunal troughs; ' (1) To prevent damage from flooding, while recognizing that natural fluctuations in water levels are beneficial; - I (m) To protect, restore, and maintain the habitat of fish and wildlife; and (n) To ensure the attainment of these objectives by requiring the approval and implementation of stormwater management plans for all activities which may have an adverse impact upon community waters. , SECTION FOUR: DEFINITIONS Unless specifically defined below, words or phrases shall be interpreted so as to give them ' the meaning they have in common usage and to give this ordinance its most effective application.

The appeal shall be filed in writing within twenty (20) days of the date of official transmittal of the final decision or determination to the applicant, shall state clearly the grounds on which the appeal is ' based, and shall be processed in the manner prescribed for hearing administrative appeals under local and NC State Statutes. ' SECTION EIGHT: PERFORMANCE STANDARDS The Stormwater Management Plan must demonstrate the proposed development or activity ' has been planned and designed and will be constructed and maintained to meet each of the following standards: (a) Ensure that after development, runoff from the site approximates the rate of flow, volume and timing of runoff that would have occurred following the same rainfall under existing conditions and to the extent practicable, predevelopment conditions, unless runoff is discharged into an Off -site Drainage Facility as provided in Section Ten;- (b) Maintain the natural hydrodynamic characteristics of the watershed; (c) Protect or restore the quality of ground and surface waters; (d) Ensure that erosion during and after development is minimized; (e) Protect groundwater levels; (f) Protect the beneficial functioning of wetlands as areas for the natural storage of surface waters and the chemical reduction and assimilation of pollutants; (g) Prevent increased flooding and damage that results from improper location, construction, and design of. structures in areas which are presently subject to an unacceptable danger of flooding; (h) Prevent or reverse salt water intrusion; (i) Protect the natural fluctuating levels of salinity in estuarine areas; 0) Minimize injury to flora and fauna and adverse impacts to fish and wildlife habitat; (k) Otherwise further the objectives of this Ordinance. SECTION NINE: DESIGN STANDARDS To ensure attainment of the objectives of this Ordinance and to ensure that performance standards will be met, the design, construction, and maintenance of drainage systems shall be consistent with the following standards: (a) Channeling runoff directly into waterbodies shall be strictly prohibited. Instead, runoff shall be routed through swales and other systems designed to increase time of concentration, decrease velocity, increase infiltration, allow suspended solids to settle, and remove pollutants; (b) Natural watercourses shall not be dredged, cleared of vegetation, deepened, widened, straightened, stabilized, or otherwise altered. Water shall be retained or detained before it enters any natural watercourse in order to preserve the natural hydrodynamics of the watercourse and to prevent siltation or other pollution; (c) The area of land disturbed by development shall be as small as practicable. Those areas which are not to be disturbed shall be protected by an adequate barrier from construction activity. Whenever possible, natural vegetation shall be retained or protected; (d) No grading, cutting or filling shall be commenced until erosion and sedimentation control devices have been installed between the disturbed area and waterbodies, watercourses, and wetlands; (e) Land which has been cleared for development and upon which construction has not commenced shall be protected from erosion by appropriate techniques designed to revegetate the area; (f) Sediment shall be retained on the site of the development; (g) Wetlands and other waterbodies shall not be used as sediment traps during development; (h) Erosion and sedimentation facilities shall receive regular maintenance to insure that they continue to function properly; .0 7 (i) Artificial watercourses shall be designed, considering soil type, so that the velocity of flow is low enough to prevent erosion; 0) Vegetated buffer strips shall be created or, where practicable, retained in their natural state along the banks of all watercourses, waterbodies, or wetlands. The width of the buffer shall be sufficient to prevent erosion, trap the sediment in overland runoff, provide access to the waterbody and allow for periodic flooding without damage to structures; (k) Intermittent watercourses, such as swales, should be vegetated; (1) Retention and detention ponds shall be used to retain and detain the increased and accelerated runoff which the development generates. Water shall be released from detention ponds into watercourses or wetlands at a rate and in a manner approximating the natural flow which would have occurred before development; ' (m) Although the use of wetlands for storing and purifying water is encouraged, care must be taken not to overload their capacity, thereby harming the wetlands and transitional vegetation. Wetlands should not be damaged by the construction of detention ponds. ' (n) The first one and one-half (1.5) inch of runoff from impervious surfaces shall be retained on the site of the development; ' (o) Detention and retention areas shall be designed so that shorelines are sinuous rather than straight and so that length of shoreline is maximized, thus offering more space for the growth of littoral vegetation; ' (p) The banks of detention and retention areas shall a slope at gentle grade into the water 9 as a safeguard against drowning, personal injury, or other accidents, to encourage the ' growth of vegetation and to allow the alternate flooding and exposure of areas along the shore as water levels periodically rise and fall; ' (q) The use of drainage facilities and vegetated buffer zones as open space, recreation and conservation areas shall be encouraged. ' SECTION TEN: OFF -SITE DRAINAGE FACILITIES (a) The Town of Beaufort may allow stormwater runoff that is otherwise of unacceptable ' quality or which would be discharged in volumes or at rates in excess of those otherwise allowed by this Ordinance, to be discharged into drainage facilities off the site of. development if each of the following conditions is met: ' (1) It is not practicable to completely manage runoff on the site, in a manner that meets the Performance Standards and Design Standards; ' (2) The off -site drainage facilities and channels leading to them are designed, constructed, and maintained in accordance with the requirements of this ordinance; 91 (3) Adequate provision is made for the sharing of construction and operating costs of the facilities with the town. The developer, may be required to pay a portion of the cost of constructing the facilities as a condition to receiving approval of the drainage plan; (4) Adverse environmental impacts on the site of development will be minimized. (b) At request to use off -site drainage facilities and all information related to the proposed off -site facilities should be made a part of the developer's Stormwater Management Plan. Guidelines for the consideration of off -site facility use will be defined in the Manual of Stormwater Management Practices. SECTION ELEVEN: MANUAL OF STORMWATER MANAGEMENT PRACTICES (a) The Town of Beaufort shall compile a manual of Stormwater Management Practices for the guidance of persons preparing Stormwater Management Plans, and designing or operating drainage systems. The Manual shall be updated periodically to reflect the most current and effective practices and shall be made available to the public. (b) The Manual shall include guidance and specifications for the preparation of Stormwater Management Plans. Acceptable techniques for obtaining, calculating, and presenting the information required in the Stormwater Management Plans shall be described. (c) The Manual shall include guidance in the selection of environmentally sound practices for the management of stormwater and the control of erosion and sediment. Specific techniques and practices shall be described in detail. The development and use of techniques which emphasize the use of natural systems shall be encouraged. (d) The Manual shall also establish minimum specifications for the construction of drainage facilities. Construction specifications shall be established in accordance with current good engineering practices. (e) The Building Inspector shall submit the Manual and subsequent revisions of it to the Town Board and Planning Board for review and approval. SECTION TWELVE: MAINTENANCE (a) Drainage facilities shall be dedicated to the Town of Beaufort where they are determined to be appropriately a part of the town's maintained system or are unlikely to be adequately maintained by the developer or owner of the property. (b) The systems maintained by the owner shall have adequate easements to permit the town to inspect and, if necessary, to take corrective action should the owner fail to properly maintain the system. Before taking corrective action, the town shall give the owner written notice of the nature of the existing defects. If the owner fails within thirty (30) days from the date of notice to commencement corrective action or to appeal the matter to the Town Board of Commissioners, the town may take necessary corrective action, the cost of which shall become a lien on the real property until paid. lj ' SECTION THIRTEEN: ENFORCEMENT (a) Nuisance: Any development activity that is commenced without prior approval of a ' Stormwater Management Plan or is conducted, contrary to an approved Stormwater Management Plan as required by this Ordinance, shall be deemed a public nuisance and may be restrained by injunction or otherwise abated in a manner provided by law. (b) Civil and Criminal Penalties: In addition to or as an alternative to any penalty provided herein or by law, any person who violates the provisions of this Ordinance shall be ' punished by a fine of not less than One Hundred Dollars ($100) nor more than One Thousand Dollars ($1,000) or by imprisonment in the county jail for a period not to exceed sixty (60) days, or by both such fine and imprisonment. Such person shall be guilty of a separate offense for each day during which the violation occurs or continues. (c) Any violator may be required to restore land to its undisturbed condition. In the event ' that restoration is not undertaken within a reasonable time after notice, the town may take necessary corrective action, the cost of which shall become a lien upon the property until paid. ' (d) Notice of Violation: When the Town Building Inspector determines that development activity is not being carried out in accordance with the requirements of this Ordinance, it shall issue a written notice of violation to the Owner of the property. The notice of violation ' shall contain: (1) the name and address of the owner or applicant; ' (2) the street address when available or a description of the building structure, or land upon which the violation is occurring; (3) a statement specifying the nature of the violation; ' (4) a description of the remedial actions necessary to bring the development activity into compliance with this Ordinance and a time schedule for completion of such remedial action; ' (5) a statement of the penalty or penalties that shall or may be assessed against the person to whom the notice of violation is directed; (6) a statement that the town's determination of violation may be appealed to the Town Board of Commissioners by filing a written notice of appeal within fifteen (15) days of service of notice of violation. The notice of violation shall be served upon the person(s) to whom it is directed either personally, in the manner provided for personal service of notices by the court of local jurisdiction or by mailing a copy of the notice of violation by certified mail, postage prepaid, return receipt requested to such person at his or her last known address. A notice of violation issued pursuant to this section constitutes a determination from which an administrative appeal may be taken to the Town Board of Commissioners. 93 SECTION FOURTEEN: SEVERABILITY Each separate provision of this Ordinance is deemed independent of all other provisions herein so that if any provision or provisions of this Ordinance be declared invalid, all other provisions thereof shall remain valid and enforceable. SECTION FIFTEEN: EFFECTIVE DATE This Ordinance shall become effective on Adopted this the day of , 19 Mayor Reviewed for Legal Consistency: Town Attorney Date XV. PARKING LOT PAVING As an additional aid to the control of stormwater runoff, the town should consider not requiring parking lots with 25 spaces or less to be paved. In addition, the town should consider allowing parking lots which are infrequently used, one day or less per week, to be constructed with pervious surfaces. Large infrequently utilized parking lots (greater than 25 spaces) should be treated as special uses and approved on a case by case basis by the Town of Beaufort Board of Adjustment. Drawings 1 and 2 provide example details for unpaved parking lots. These details are presently being utilized by the City of Wilmington, North Carolina. 94 1 1 Drawing 1 Typical Unpaved Parking Facility Under 25 Stalls 1 1 1 1 1� 1 1 1 1 1 1 1 . 1 1 f►� r a 1 � 41TE PAINT ON •- AND FACE PERIMETER ;••aD. 24- DRAINAGE TRENCH 14AWICAP PAVED 1 7 tjA I -a -�/ ■ F_i=1_ ;1 A t • GRID RE INFORCE30417 to DIA ROD • 1 •1 •iWit I it :!a • • (RPNE9•�:• 6'0 ouo NONWOI � o v°` o°o REOiEXTL Tz'�" C EFAR I .57 o ANo. °o0o' °°o GRAVEL.

' XVI. SUBDIVISION ORDINANCE ' The Town of Beaufort Subdivision Ordinance should be updated and rewritten. This should be done to respond to changes in the state's enabling legislation regulating land subdivision and to coordinate the subdivision ordinance with revisions to the Zoning ' Ordinance and the new Stormwater Control Ordinance, if adopted. In 1991, the legislature adopted revisions to the state's platting requirements. The state's recordation requirements were revised in 1993. Specifically, the following zoning ordinance revisions may require modifications to the town's subdivision ordinance: ' — Industrial Park regulations. — Landscaping requirements. ' — Establishment of nonresidential minimum lot sizes. — Establishment of nonresidential yard requirements. — Zero lot line/townhouse for individual ownership requirements. XVII. DEMOGRAPHIC FORECAST From 1995 to 2005, the Town of Beaufort and the unincorporated areas of the Beaufort township are expected to grow 15.08% and 30.16%, respectively. These growth rates are expected to continue through the 10-year planning period as defined by the Town of Beaufort 1996 CAMA Land Use Plan. In 1996, the total population within the primary and ' secondary impact areas was 1,098. At the forecast growth rate of 30.16%, the total 2005 population should be approximately 1,429. At an average household size of 3.3, the ' resulting number of households is approximately 433. ' Long term build out of the primary and secondary areas based on the proposed Land Use Plan (see page 28) will require considerably longer than 2005. The proposed plan provides residential development in residential corridor areas, medium to high density ' residential areas,and low density residential areas. The following provides the average densities for each of these areas: Residential Corridor 3.5 dwelling units/acre Medium to High Density Residential 5.5 dwelling units/acre ' Low Density Residential 3.5 dwelling units/acre I NOTE: Densities have been adjusted to accommodate road right-of-ways. 97 The residential density for the residential corridor area is only 3.5 dwelling units per acre because 50% of the area is expected to be developed for office and institutional usage. Those residential corridor areas which are developed for residential usage should have an average residential density of seven dwelling units per acre. Based on these average densities, the following total dwelling units may be constructed: Residential Corridor 71 dwelling units Medium to High Density Residential 525 dwelling units Low Density Residential 1123 dwelling units 1719 total dwelling units Total build -out would result in a population base of 5,672 (1,719 x 3.3 average household size). At the current growth rate of 30.16% per ten year period, build -out would require in excess of 60 years. Table 7 summarizes population growth at a sustained 30.16% growth rate per ten year period. Table 7 U.S. 70 Corridor Study Primary and Secondary Impact Areas Long Term Forecast Growth 2005 1,429 2015 1,859 2025 2,420 2035 3,151 2045 4,101 2055 5,338 XVIII. TRIP GENERATION The traffic/transportation implications of population growth will be significant. Normally a household will generate an average of eight vehicular trips per day. Thus, the existing 331 households generate approximately 2,648 vehicular trips. By 2005 and 2015, the total number of trips will have increased to approximately 3,464 and 4,506 per day, respectively. These figures do not reflect transient traffic which will be moving through the area. XIX. WATER AND WASTEWATER UTILITY DEVELOPMENT ' A. Introduction Estimation of full development utility demands in the primary and secondary impact areas ' are based upon projected land use patterns as indicated on Map 8. Water/wastewater demands allocated to the various projected land uses and applied to utility design requirement projections are as follows: Residential Corridor 400 gpd/acre Low Density Residential 400 gpd/acre Medium to High Density Residential 800 gpd/acre ' Non -Residential Corridor 500 gpd/acre High Density Commercial 500 gpd/acre Industrial 200 gpd/acre For each land use, it is estimated that 10 percent of the acreage will be utilized for right-of- ways and other public use purposes. Therefore, the above flow rate demands will be applied to 90 percent of each land use total acreage. Several areas within and adjacent to the southernmost boundary of the impact areas are presently served by public water, sewer or both. However, the majority of the impact area ' is not served with such utilities and a master plan for such service is desirable. A master plan for water and wastewater service to the approximately 1,500 acres of impact area should set the course to enable future development to ultimately result in the most long- term cost-efficient utility systems to operate and maintain. ' B. Water ' 1. General ' A public water supply system to serve the impact area will consist of three major components: a water distribution system; water supply source and treatment capacity; and water storage capacity. a. Distribution in General The distribution system is a piping network consisting of trunk mains and distribution mains which transport the potable water supply to the individual users from the 99 source or storage location. Trunk mains are the larger sized lines designated primarily to move water from its source to and through the service area. Distribution mains are smaller lines primarily intended to distribute and deliver water to individual users in any locale within the water system's service area. The distribution system should contain "looping" connections in as much as possible to provide assurance for continued service even in the event of unexpected disruption. However, this is not always initially possible as systems expand into adjacent unserved areas, as is the case in the instance of the impact area. Transportation corridors will directly impact location of the primary (trunk) lines. Hydrants are placed at strategic locations throughout distribution systems, including trunk mains, to provide mechanisms for flushing maintenance of the pipeline network. Spacing is normally driven by economic and political considerations. Traditionally, hydrant placement is interpreted as being primarily for community fire protection. As a result, placement for this maintenance necessity benefits from the locally desired frequency of water sources for community fire protection. In the Beaufort water system, current policy places hydrant spacing at 500 feet within the Town's corporate limits and 2,500 feet beyond the corporate limits. Valves should be placed liberally in the construction of extensions to allow isolation of various lines of the distribution network without disruption to large portions of the system. b. Water Supply/Treatment in General Water supply sources normally include: groundwater, surface water; reuse; and purchase from a regional supplier. In coastal North Carolina, water supply sources are typically groundwater, either directly or indirectly through a regional supplier. Required treatment normally includes any combination of iron removal, softening, reverse osmosis, fluoridation and disinfection. C. Water Storage in General Storage of water is regulated by the State of North Carolina to be the equivalent capacity of one-half of the annual average day supply. Storage is provided in both ground and elevated storage tanks. Elevated tanks tend to be the preferred choice as they also provide for sustaining the desired system operating pressure throughout the distribution network. 100 ' 2. Water Distribution System Expansion The objective of the water distribution network expansion will be to provide appropriate ' conduits within which to transmit maximum day water demands to the various portions of the impact area, and to a reasonable extent, for future service beyond the impact area. ' Minimum water line size recommended is 6 inch so as to be capable of accommodating installation of hydrants. Hydrant spacing is initially recommended at the current town policy of 2,500 feet for out-of-town locations (of which is the case for the majority of the ' impact area). ' A schematic plan for the primary piping of a water distribution network expansion as well as identification of existing water distribution renovations required by new highway construction are shown on Map 9. The plan is not intended to depict the actual location ' of lines, hydrants and valves, but instead to illustrate a proposed concept. ' A preliminary opinion of probable cost for these water system extensions and renovations is shown on Table 8. The generally estimated project cost for all improvements is ' $1,335,000 as expressed in 1997 dollars. This cost, or any portion thereof, adjusted for inflation, should only be used for planning purposes. For budgeting, it is recommended that the individual project to be implemented be specifically evaluated for actual proposed ' cost. 1 101 � 'I � III 1 1 1 1 i 1 1 1 -Lamm POAVY AFACr AREA SOUNDAV SECCAIDARY AkVACT AREA BOUNDARY PROPOSED kfChVAY COARVOR AND ACCESS LOCAVOV Emma Z)WR (87 DUSW FORCE AMN PROPOSED SENN —FM— PROPOSED FORCE "W PRoPosm vAam mw srAwv EVSIM WA IV PROPOSED WA MR 1p WR-3 RELOCATE HATER GR-2 MUCATE GRAVITY SEIM— *R-2 RKWCATZ HATER G7-1TE RUWa GR4 VTTr R CA =7 KWAO SZW LFR LS #1" M Tf m.,,o LS, ► LI LIS 0 WEST #7 ig N MAP 9 TOWN OF BEAUFORT S 70 PRIMARY AND SECONDARY -T�uS IMPACT AREA PROPOSED PRIMARY WATER AND WASTEWATER SYSTEMS EXTENSIONS AND RENOVATIONS C4RTERET COUNTY NORTH CAROLMA 6 L S u 3\1)" x/. 0.3 MG GROUND STORAGE TANK,' LS #12 WATER TREATMENT PLANT NO. 800 qpm--lrAL- 717 7-1 --1 NEW rm 70 iWrTP X, am 14 mor Nam m or- mw Entineers 107 Seat Seemed 3L Planners Since gremvm*l N.C. 279" 1918 (919) 752-4136 Surveyors DRAWING NO.

Water Storage Capacity The Town of Beaufort's installed water storage capacity far exceeds the regulatory ' requirement. The existing capacity will also provide for the demands projected at full development of the impact area. Table 9 includes a summary of existing storage capacity ' versus projected demands resulting from full development in the impact area. C. Wastewater 1. General A central sewer system to serve the impact area will consist of two major components: a 1 wastewater collection system; and wastewater treatment system capacity. The collection system is a piping network consisting of collector mains and interceptor mains which receives the generated wastewater from individual users and transports it to the treatment location. Collector mains are the smaller pipelines designated to receive the ' wastewater from the individual users, while the interceptor mains are the larger pipelines primarily designated to transport collected wastewater to the wastewater treatment plant ' or a collection system pump station. In this instance, wastewater collected from the impact area should be transported directly to the wastewater treatment plant to avoid overloading the multiple pumping stations in the existing wastewater collection system. The treatment system receives the transported wastewater and subjects it to various ' degrees of physical, biological and (in some cases) chemical treatment processes to reduce the water borne waste constituents to acceptable levels prior to discharge onto land or into surface waters. 2. Wastewater Collection System Expansion ' a. General ' There are various methods by which wastewater collection can be satisfactorily accomplished. Each method can have "pro and con" features which may result in one 1 option having an advantage for its utilization in a particular community. Therefore, at a minimum, a general evaluation of potential methods should be conducted. b. Gravity Collection Alternative ' A gravity collection system has one primary component, that being a piping network designed at a slope to utilize the earth's gravitational pull to cause the wastewater from ' each user to "run" downhill away from the home (or business). The wastewater flows through the piping network en route to its ultimate destination. There is no special ' equipment, valve, pump, tank, etc. required at the user's location or at other locations to remove the user's wastewater. ' However, in coastal North Carolina communities, where topography is essentially non-existent, the required sloping of the pipeline creates an ever deepening pipeline trench, thus encountering groundwater, unsuitable soils, hazardous working conditions, and other unforgiving obstacles. These problems can only be overcome by construction of , expensive lift (or pump) stations. In areas such as the impact area where topography does not exist and groundwater ' tables are shallow due to the low elevation relative to mean sea level, the frequency of pump stations is accelerated due to its cost-effectiveness over extension of ever -deepening , gravity pipelines. In general, this results in a maximum reach of approximately one -quarter to one-half mile of gravity sewer in either direction from a pump station. ' Additionally, gravity sewer pipeline construction typically requires extensive area for construction of the deep trenches. Many times, this occurs through areas with developed , surface features which must be replaced or through limited space areas. Both situations result in increased cost of construction. C. Low Pressure Collection Alternative ' A low pressure collection system consists of individual service pumps and a small diameter pressure piping network. Each individual user's service connection includes ' either a new septic tank with "effluent" pump (in the case of a STEP system) or a liquid chamber containing a "grinder" pump (in the case of a grinder system). The STEP system retains solids in the septic tank for separate disposal, while the grinder system converts ' biosolids into a slurry which is pumped through the collection system. An electri cal connection is required for each user's pump. In instances of older structures, the electrical service usually requires upgrading to handle the electrical load of the pump. , 106 ' The pumps are low horsepower submersible effluent pumps with controls installed at the user's location. Minimal emergency storage is provided in each tank along with entry ports for maintenance and sludge removal (STEP only). The service lines and force mains are installed with 3 to 7 feet of cover, thereby ' eliminating deep trench cuts and minimizing potential groundwater table conflicts. This is accomplished as a result of the "pressure" operation, which provides the ability to overcome terrain and underground obstacles. Due to acceptable velocity operating ranges of 1-4 feet per second at average flow, small diameter piping can be utilized. For a grinder system, the minimum pipeline velocity is 2 feet per second. In STEP systems, accumulated sludge must be removed from the septic tanks on ' a routine basis (normally 3-8 year cycle). This requires either: contracted sludge pumping and hauling; or the purchase and maintenance of a sludge pumping vehicle. For either STEP or grinder systems, special equipment is required for high pressure cleaning of the -collection piping network and _maintenance responsibility for the users' ' pumps and control should be with the operating entity to ensure reliability and emergency response preparedness. ' d. Vacuum Sewer Collection Alternative ' A vacuum sewer operates exactly how its name implies - sewage is transported from the user via vacuum. There are three primary components to the system: the interface valve and collection pit package, the vacuum collection piping, and the vacuum ' collection pump station. Sewage flows from a user's waste plumbing by gravity yard piping to the collection pit, located underground, typically alongside the street. When the pit collects approximately ten gallons, the valve opens and the sewage is then transported by vacuum to the collection pump station. The vacuum collection pump station contains three ' major equipment items: the vacuum pumps, the collection tank and the pressure effluent pumps. The vacuum pumps provide the system vacuum and pull the wastewater to the collection tank. When the collection tank is full, the pressure pumps transmit the wastewater to the treatment plant or other downstream collection station. Electrical hook- ups are not required at the individual user collection pit packages, only at the vacuum F collection station, where stand-by generators can assure operation in the event of power outages. 107 Economic efficiency is the most obvious advantage of the vacuum sewer system, especially in coastal areas where high water tables prevail. Like the low pressure systems, the vacuum system trenches are only 3 to 7 feet deep. The shallow piping system can be installed since the sewage is being pulled by vacuum to the collection station. The system also allows sewage to be lifted uphill to match ground contours and underground obstacles, and is very important in areas with high groundwater tables. The vacuum technology allows utilization of smaller piping diameters than does gravity collection systems. And as opposed to individual septic tank/effluent pump or grinder pumps required in low pressure collection systems, a standard vacuum sewer collection pit package can accommodate up to four adjacent residential users. Special collection pit packages are utilized for larger flow users. While vacuum technology allows utilization of smaller piping diameters than comparatively required for gravity collection systems, lines may initially be designed larger than required for low pressure collection systems. Consequently, the vacuum system is less vulnerable to initial flow design requirements becoming inadequate as a result of progression towards full anticipated development. Vacuum collection systems are limited only by the physical limitations of the vacuum collection pump station design. Properly designed to its feasible limits, vacuum collection pipelines have a maximum reach of approximately one mile in either direction from the vacuum collection pump station. e. Wastewater Collection System Plan Selection Each of the three alternatives have their unique "pros and cons". To determine the most appropriate alternative for implementation, it is necessary to compare the basic features of each. To do so, it is useful to utilize a rating system as follows: +3 Highly Favorable +2 Favorable +1 Moderately Favorable 0 Neutral -1 Moderately Unfavorable -2 Unfavorable -3 Highly Unfavorable Public disruption - gravity collection rates as highly unfavorable (-3) due to massive trenches required as opposed to shallower trenches similar for low pressure and vacuum. Pump tank excavations on each user's property result in a moderately 108 ' unfavorable (-1) rating for low pressure while vacuum rates as moderately favorable (+1). ' Ease of Construction - Construction methods required to construct gravity sewer cause this parameter to be rated as highly unfavorable while both low pressure and vacuum sewer rate as favorable (+2). Expansion Capability - Within the impact area, gravity sewer and vacuum sewer are expandable without retrofitting existing pipelines as might be required for low pressure sewer. Depending on location, an additional pumping station could be trequired for gravity sewer. Vacuum will be rated highly favorable (+3), gravity as moderately favorable (+1) and low pressure as unfavorable (-2). Requirement of Improvements On/For Private Property Service - Low pressure systems require new tankage/pumps and electrical service to pump motor at each user (-3) in addition to the gravity yard piping required for gravity (-1) and vacuum. Vacuum requires a collection valve pit that serves up to four users (-2) in addition to the gravity yard piping. Operation and Maintenance - Gravity sewer rates as moderately favorable (+1) since at least four pump stations would be required to service the impact area. Vacuum sewer rates moderately unfavorable (A) as vacuum collection pits equivalent to at least 25 percent of the users will be required in addition to the main vacuum collection pump station. Low pressure sewer rates highly unfavorable (-3) as there exists a pump, control panel enclosure, float control switches and potentially a septic tank (for a STEP system) at each user location. Environmental Issues - Each alternative will resolve potential site specific environmental wastewater problems while increasing the wastewater loading at the wastewater treatment plant. The rating for each alternative is therefore neutral (0). ' Reliability - the vacuum sewer system has one location to ensure reliability against spills. This location is the vacuum collection pump station which has stand-by power on -site to ensure continued service (+3). Gravity sewer is similar but ' requires permanent auxiliary equipment at multiple facilities or portable equipment to attempt sharing between the multiple facilities, resulting in a moderately favorable rating (+1). Low pressure sewer service is disrupted at each user during commercial power failure (-3). 109 Financial - Surveys conducted of the three alternative systems on projects , constructed in eastern North Carolina in the early 1990's indicate that gravity systems are the most expensive to construct ($49/1-F average), therefore rating as highly unfavorable (-3), followed by low pressure ($44/1-F average) and vacuum ' ($31/LF average). Low pressure will be rated as neutral (0) while vacuum sewer will be assigned a highly favorable (+3) rating. ' Composite Rating Matrix Low ' Gravity Pressure Vacuum Public Disruption -3 -1 +1 Ease of Construction -3 +2 +2 Expansion Capability +1 -2 +3 Required Improvements On/For -1 -3 -2 ' Private Property Service Operation and Maintenance +1 -3 -1 Environmental Issues 0 0 0 ' Reliability +1 -3 +3 Financial -3 0 +3 ' Totals -7 -10 +9 , Composite Ranking 2 3 1 The low pressure alternative ranks as least favorable in terms of the parameters ' considered. This alternative is attractive to accommodate sparsely located cluster development and small towns. However, it is a less than desirable alternative for a large ' developing area as the pressure piping network (which must be designed for initial flows) can accommodate growth only up to the maximum desired design flow velocities. Further, as growth development occurs, available emergency storage decreases. Therefore, ' pipelines designed to accommodate initial flows are normally insufficient to provide for demands at full development. I Gravity sewer ranks as a slightly more favorable alternative than low pressure sewer in terms of the parameters considered. While it ranks positively in terms of , reliability, operation/maintenance and expansion capability, it is the least desirable in terms of ease of construction, public disruption and resulting cost of financial resource I investment. 110 ' Vacuum sewer ranked far above the other alternatives in terms of the parameters considered. It rated as high or higher than the other alternatives for most of those ' parameters. It offers the greatest ease of construction, the least public disruption, the greatest ease of expansion capability, and the greatest reliability as well as being the most cost-effective to construct based on comparative surveys. ■ Several minor areas can be served by extension of existing gravity sewer mains and should be so served. Two areas require relocation of existing gravity sewer mains, pump station and/or force main to maintain existing service as a result of proposed highway construction. Beyond such extensions and relocations, a vacuum sewer system is recommended for implementation in areas currently without service. This recommendation is based upon evaluation of all aforementioned considerations. ■ A schematic plan for the primary piping of a vacuum sewer system as well as identification of existing gravity sewer renovations required by new highway construction is shown on Map 9. The plan is not intended to depict the actual location of lines, pump stations and appurtenances, but instead to illustrate a proposed concept. A preliminary opinion of probable cost for these sewer system extensions and renovations is shown in Table 10. The generally estimated project cost for all improvements is $2,703,000 as expressed in 1997 dollars. This cost, or any portion thereof, adjusted for inflation, should only be used for planning purposes. For budgeting, it is recommended that the individual project to be implemented be specifically evaluated for actual proposed cost.

Wastewater Treatment The existing wastewater treatment plant easily accommodates existing flows. However, tbased on projected flow demands from the proposed land uses in the impact area, the existing permitted capacity will not be sufficient to accommodate the total projected WWTP ' demands of 1.75 MGD for maximum month average day flow. Table 11 illustrates various hydraulic requirements for the Beaufort WWTP as well as the impact area.

Source: Rivers & Associates, Inc. The Beaufort WWTP currently has a stream discharge. Present inclinations are that expansion of the current 1.5 MGD permit will likely not be looked favorably upon by the State of North Carolina's Division of Environmental Management, which is the regulatory 113 agency. With the availability of ocean outfall disposal seemingly still years into the future for North Carolina, land application appears to be the only viable opportunity for expansion. However, without detailed engineering studies and permits issued by the State regulatory agency, evaluation of treatment costs associated with the impact area and WWTP expansion are based upon the generally accepted value of $3.00 per gallon for advanced treatment facilities with stream discharge. This value could increase to over $5.00 per gallon should additional nutrient removal under consideration by the state regulatory agency be implemented. For land application, a value of $10.00 per gallon will be utilized. Impact Area WWTP Flow Demand Costs: 418,000 GPD @ $3.00/gal. _ $1,254,000 Stream Discharge @ $5.00/gal. _ $2,090,000 Stream Discharge with Nutrient Removal @$10.00/gal.= $4,180,000 Land Application WWTP Expansion Cost to Accommodate Impact Area: 250,000 GPD @ $3.00/gal. _ $750,000 Stream Discharge @ $5.00/gal. _ $1,250,000 Stream Discharge with Nutrient Removal @$10.00/gal. = $2,500,000 Land Application When WWTP expansion planning and construction is required will be a function of how quickly development occurs in the impact area and how that developmental growth impacts the "80/90" rule from North Carolina's Administrative Code. 15A NCAC 2H.0223 requires that engineering studies for provision of future wastewater treatment needs to be completed and submitted for approval prior to the annual average day flow reaching 80 percent of the treatment facility's permitted capacity. The code also requires that construction plans be prepared and applicable construction permits received for any required expansion or improvements necessary to meet those future needs prior to the annual average day flow reaching 90 percent of the treatment facility's permitted capacity. To avoid violations of the NPDES discharge permit and moratoriums on future service connections to the wastewater system, plans for expansion/improvements must be constructed and operational prior to the maximum month average day flow to the WWTP exceeding the facility's permitted capacity. 114 XX. STORMWATER SYSTEM DEVELOPMENT A. Introduction That portion of precipitation which does not infiltrate into the soil or remain in surface tdepressions is generally referred to as stormwater runoff. Stormwater runoff from the impact areas gradually drains towards the Newport River to the west, Gibbs Creek to the east, Turner Creek to the southeast and Town Creek to the southwest. The ground elevation is very near mean sea level throughout the impact areas with very little ' topographical relief. As a result, stormwater is slow to drain from the existing ground surface. As a large majority of the existing land use in the impact area is vacant, slow or impeded drainage is not normally a problem except perhaps to farming and septic tank operations. B. Stormwater Design Considerations The extreme southern portions of the impact areas currently contain concentrated development and are already provided with various methods of stormwater drainage. Other portions of the impact areas are either currently vacant or developed to a minor ' degree in terms of overall effect on area -wide stormwater management planning. ' Accomplishing the transportation of stormwater from any number of various specific sites to one or more primary surface water discharge locations is difficult to evaluate. Many factors influence the design of storm sewer conduits and open channels, such as: 1. Desired return frequency of storm event. 2. Precipitation intensity and duration. 3. Land uses in drainage area. 4. Nature of specific site(s) (pervious vs. impervious surface area). 5. Topographic relief from collection point to discharge point. 6. Soil types. ' 7. Maximum length of travel. 8. Type(s) of conduit or channel. The desired return frequency is the frequency with which a given event is equaled or exceeded on the average. Five or ten year frequencies are normal for storm sewer ' designs. The less frequent the event, the more intense the precipitation. A 10-year storm event would be expected to be equaled or exceeded 10 times in 100 years, or may be said ' to have a 10 percent chance of being equaled or exceeded in any given year. 115 Type of land use and resulting site specific development will impact the amount of runoff occurring from impervious surfaces. Those impervious surfaces will also affect how quickly the runoff collects at a given location, or the time of concentration. The lack of topographical relief aids in decreasing the resulting time of concentration for runoff which decreases required conduit or channel size, yet the essentially flat terrain causes slow runoff resulting in localized flooding during higher intensity precipitation. Virtually all of the soils in the impact areas are classified as wet and subject to flooding. This negatively impacts stormwater runoff by limiting the amount of infiltration and thereby increasing volume of runoff. The type of conduit or channel affects the ability of collected stormwater to pass through it. The various shapes and materials have unique characteristics which affect their hydraulic capacities. The length of travel through the conduit or channel has an aggregate effect on the hydraulic capacity limitations. To determine the quantity of stormwater runoff, use of the Rational Method is generally accepted: Q=CiA where, Q = peak runoff rate, cfs C = runoff coefficient i = average rainfall intensity, in/hr A = drainage area, acres The rainfall intensity is a function of topographical relief, horizontal travel, travel surface, resulting time of concentration and the desired design storm event return frequency. The runoff coefficient is a function of the runoff surface characteristics and is the variable that is most susceptible to varying factors, especially in widespread application (in lieu of site specific application). The runoff coefficient multiplier varies from as low as 0.1 for unimproved open space to as much as 0.95 for heavily developed commercial land use. Suggested runoff coefficients for the proposed general land uses in the impact areas are: Proposed Land Use Rational Method Classifications Runoff Coefficient Low Density Residential 0.30 Residential Corridor 0.40 Medium to High Density Residential 0.75 Non -Residential Corridor 0.75 Commercial High Intensity Focus Area 0.95 Industrial 0.80 Airport 0.30 116- ' C. Types of Stormwater Svstem Improvements ' Stormwater is generally transported through variations of two basic types of improvements: conduit or channel. Conduits typically include closed structures such as piping or culverts. Channels are normally considered as open systems with either vegetative, protected or ' impervious liners. For the impact area, some combination of conduits and channels will most likely be required to provide for development of a stormwater sewer system. Conduit ' systems, starting at costs of approximately $25 per linear foot of pipe installed, are generally more expensive to build per unit of hydraulic capacity but are more manageable and aesthetically pleasing than open channels in many instances. Unlined open channels, costing approximately $9 per cubic yard of channel volume, are primarily used in underdeveloped areas and as the major artery to transport stormwater collected from multiple conduits away from a general area to the ultimate discharge location. The aesthetics and maintenance performance of open channels can be enhanced by ' installation of channel liners at an approximate cost of $345 per square foot of channel surface area. D. Recommendations for Stormwater System Development The impact areas contain over 1,500 acres with proposed land uses of various development intensities. The area is generally flat with drainage patterns that are not always obvious and consists of saturated soils not conducive to infiltration of precipitation. As future development begins to occur, patterns will begin to emerge for accommodating site specific drainage needs. The object of the Town of Beaufort's goals for facilitating future drainage needs in the impact areas should be to outline primary drainage corridors which will accommodate the site specific needs. To do so will require a separate detailed study to: determine appropriate hydraulic capacities; evaluate topographical features and existing physical improvement limitations; preliminarily identify primary drainage corridors; prepare a stormwater design matrix for the primary drainage corridors; and determine the Icost of development for each corridor. ' Due to the negative impacts associated with lack of topographical relief, poor soil conditions and the sensitivity of receiving waters, the Town should consider adopting regulatory control for on -site detention of stormwater as a method to minimize the ' requirements for stormwater transportation facilities and environmental impact. Adoption of such control conforms to the recommendations of Section XIV. STORMWATER ' MANAGEMENT of this report. 117 XXI. WATER, WASTEWATER AND STORMWATER IMPLEMENTATION A. Summary 1. General Development "driven" by planned strategy tends to be more beneficial than development which "drives" strategy. While the initial cost/benefit of development is often the primary factor in determining implementation plans, the primary factor should be the goal to develop for the future. Comprehensive master plans should include: identification of methods to create administrative strategies to facilitate implementation; identification of phasing plans; development of funding strategies; creation of planning/public works tools and documents to facilitate implementation policies; and set capital improvement priorities for investment of public funds. There are no physical obstacles that cannot be overcome to provide water, wastewater and stormwater infrastructure within the primary and secondary impact areas. Cost efficient development of the areas will normally demand that the primary infrastructure facilities be initially sufficient so as to eliminate costly retrofit construction of those same facilities at a later date. 2. Water The Town of Beaufort's water supply and storage is currently sufficient to provide for the projected demands of the impact areas. However, as the Town develops within these areas, the water distribution network will expand, creating new demands for transmission of water between older and new portions of the piping network. Development of an overall computer database mapping system and an evaluation of the hydraulic characteristics of the water system will create tools for identifying any existing deficiencies, for future water system planning and for evaluation of the effects of new requests for major water service demand. 3. Wastewater The Town's wastewater treatment facility annual average day flow is nearing the "80 percent" rule by which the Town should develop a strategy to show how it intends to either reduce its waste flow or expand its facility to accommodate future growth. Development of this strategy should occur in the immediate future so as not to impede the Town's normal growth, even without development of the impact areas. Initial review of basic 118 ' water/wastewater data indicates a tremendous problem with infiltration. Approximately fifty- three (53) percent of the annual average daily flow received at the wastewater treatment ' plant is a result of infiltration of groundwater and/or inflow of surface (or rain) water. An effective strategy for wastewater planning will begin with preparation of an overall ' computer database mapping system and evaluation of the integrity of the existing collection system. Identification of sources for extraneous water entry may lead to a cost-effective ' solution for treatment capacity needs to accommodate normal growth as well as development of the impact areas. 4. Stormwater The geography of the area basically sets the perimeters within which solutions to surface drainage can be determined. Not unlike other coastal Carolina communities, the limitations ' established by these perimeters are severe. Left undeveloped, drainage of the land is not a primary concern to the human environment. However, as development begins and then desires to continue, two primary changes occur. First, the geography is changed by man's "improvements" to the land. Contouring and ' creation of impervious surfaces increases and accelerates surface runoff, creating the potential for new problems downstream of the developed site. As development continues, ' this problem potential multiplies. Second, as the potential for development created drainage problems continues to grow, ' proper drainage (or the lack thereof) increasingly will become a primary concern to the human environment. Those directly affected will rightly demand a proper response that in some instances may be too costly to implement in retrospect. Comprehensive planning for development strategy should therefore include detailed evaluation of existing and proposed drainage watersheds with plans for existing upgrades where required and plans for future primary drainage patterns for development ' projections. B. Recommendations To develop a comprehensive plan for its future, the following items are recommended for ' implementation by the Town of Beaufort. The Town should consider implementation of as many of these recommendations as possible in the near future. In place policies, 119 ordinances, tools, documents and plans can guide the Town to its desired future without , unexpected costly obstacles, deterrents or retrofitting. The recommendations will involve either water, wastewater or stormwater infrastructure ' and are categorized as either "administrative/operational needs" or "public works engineering needs". The items listed in each category are prioritized according to their projected importance to the Town's future. For planning purposes, an approximate cost for each item is provided. Either item for which the Town desires to budget appropriations should be independently evaluated with an identified scope of work for a more exact ' budget cost. Administrative/Operational Priority Needs 1. Public Works Standard Specification $6,000 Have document prepared and adopted which addresses Town standards for water, sanitary sewer, storm sewer and street construction. Sets minimum acceptable standards. Used primarily as a tool for , developers, engineers, planners and builders. Helps ensure integrity and compatibility of new installations. 2. Stormwater Management Plan $6,000 Have document prepared and adopted which addresses standards for design, development and implementation of surface water runoff, containment , and control. 3. Geographic Information System - Land Use & Zoning $25,000 ' Establish layers with database limited to available existing inventory data. Public Works Engineering Priority Needs ' *1. Geographic Information System - Water & Sewer $30,000 Establish initial layers with database limited to available existing data for water and sanitary sewer systems. *1. Infiltration/Inflow Study $45,000 Evaluate existing condition of sanitary sewer collection , system with emphasis on identification and quantifying groundwater and surface water entry. Establish costs for rehabilitation and recommend cost-effective actions to decrease flow to existing WWTP. , 120 1 "1. Comprehensive Water Study $30,000 Prepare a hydraulic computer model of the existing water distribution system and analyze water production/ consumption records. Evaluate existing various critical ' fire flow requirements, projected 20-year expansions and resulting demands upon existing piping network. ' Prepare preliminary corrective action plans with cost estimate for noted deficiencies. Use model to analyze and plan all future expansions and connections. ' 2. Stormwater Drainage Study $30,000 Conduct semi -detailed hydrological study of watersheds serving US 70/NC 101 primary and secondary impact areas. Establish preliminary plan for primary drainage in these areas along with estimated costs. 3. Geographic Information System - Drainage $25,000 Conduct field survey and establish layer with database limited to available existing data for storm sewer system. 'Based on the data contained in its 1992 Water Supply Plan and the development potential from normal growth as well as from the impact areas, it is considered that the Town of Beaufort is in a situation where an immediate response is necessary for implementation of a GIS system for water and sanitary sewer, an infiltration/inflow study and a comprehensive water study. Therefore, all ' three items are rated as a number 1 priority for public works engineering needs. XXII. ALTERNATIVE CORRIDOR LOCATION The concepts and recommendations contained in this report are based on the preliminary corridor locations which have been proposed in feasibility studies conducted by the North Carolina Department of Transportation. While the proposed corridor locations offer many positive improvements for Beaufort's planning jurisdiction, the town has identified alternative corridor locations which it believes will be more beneficial. This alternative corridor location is delineated on Map 10. The town believes this to be the preferred location for the following reasons: ' -- The revised corridor locations will be less disruptive to existing development. — The revised corridor locations will better serve undeveloped sections of Beaufort's planning jurisdiction. 121 1 1 1 1 1 1 praparallon of ihlo mop wot llnoncad in part iqh a ipanl provldod by Iho North Caro'" I' Manayyomonl Progqrrom, through Ivndo I'd 6y Ibo Coadol Zona'ane99amanl Ad of ao amandad, •hlch b odmWolind by IM :o of Ocaan and Coadat Ruaurco igamonl, Natlonal Oceanic and Almotphorlc SCALE a too• we ow rtaa INSERT MAP MAP 10 ALTERNATIVE HIGHWAY CORRIDOR LOCATIONS 122 — The intersection of the new US 70 corridor and the existing US 70 is further north of Beaufort which will provide an inducement to spread development further north. Better interconnections of new US 70, old US 70, and NC 101 are provided. A revised corridors) location(s) would not invalidate this study. The development concepts, regulatory controls, and infrastructure improvements recommended by this report would apply to the new corridor(s) location(s). XXII. REQUIRED REVISIONS TO THE TOWN OF BEAUFORT 1997 CAMA LAND USE PLAN The 1997 CAMA Land Use Plan addressed the construction of a new US 70 corridor. Thus, the issue has been generally addressed. Modifications to the CAMA Land Use Plan should be minimal. However, the following revisions should be undertaken: — The ultimate corridor(s) location(s) should be added to the town's CAMA Land Use Plan. The policy statements should be revised to support the recommendations contained in this report. — When finalized, the transportation improvement program which addresses the final corridor location should be incorporated into the CAMA Land Use Plan. — Ultimately, the land classification map should be revised to reflect the development scheme proposed for the US 70 corridor study area. However, construction will not occur during the five-year planning period for the 1997 CAMA Land Use Plan. Therefore, the current land classification map should not be revised. 123
