PROJECT SUNIMARY: The North Carolina Wildlife Resources Commission constructed a public boat ramp with limited parking under State Permit #47-01. In July of 2004, they obtained a modification to the low-density stormwater plan to enlarge the parking area. Construction began without modifying State Permit #47-01, and the applicant received a Notice of Violation. The application at hand is a result of the need to complete the expansion of the parking area, and will be handled as a Major Modification to the existing CAMA Permit, which is set to expire on December 31, 2006. NC WRC April 1, 2005 Page 02 9. NARRATIVE DESCRIPTION: This proposal represents a Major Modification to State Permit #47-01, expiration 12/31/06. The project site is a 2.56-acre tract, averaging +7' msl in elevation, currently developed as a public boat launching facility. The property is owned by the State of North Carolina, and lies within the Carteret County community of Straits, on the northwest side of the SR 1335 bridge to Harker's Island. Visibility upon encroaching the site is low and potential for seeing turning vehicles poor, due to the wooded area immediately preceding the property. The project site fronts the North River at its confluence with Straits. An Environmental Assessment was prepared, circulated, and a FONSI accepted for the original proposal on 10/11/00. The project has been constructed in its entirety. Both a stormwater plan (SW8 001243) and a sedimentation/erosion control plan (9187 S 1) were submitted and approved for the original project, and each has been modified for this proposed expansion. The property has a sandy beach adjacent to Straits that is conducive to public use, and consequently, is a popular local fishing spot. The vegetation on site is sparse, consisting mostly of stressed shrub/scrub species above the zone of tidal influence. The shoreline of the property is vegetated sporadically with S artina alterniflora. Submerged aquatic vegetation is present adjacent to the site, more to the west side than closer to the bridge. The North River and Straits systems in this area are open to the taking of shellfish for consumption; the DWQ Water Quality Classification is SA; the waters are not designated as Primary Nursery Area by the DMF; and the Carteret County Land Use Plan classifies this area of the county as Rural, with all AEC's classified Conservation. The body of water at the project site is stated as .7 mile in width. Current soundings within the North River at the project location range from -.8' nlw to -5' nlw. As stated above, the previous permit authorized a boat ramp with access docks, a short access channel, and low-density 140' x 125' crushed stone parking that accommodates 26 vehicles. A vinyl bulkhead was constructed landward of the wetlands along the perimeter of the property under the original permit, as was a system of breakwaters along the ramp. The site has proven to be popular for launching use, and has necessitated enlarged parking. The proposal at hand is to request a modification to the permit to allow for this parking expansion. The WRC is proposing to grade 1.4 acres of high ground for the construction of an expanded parking and maneuvering area. Designing to contain stormwater onsite, the applicant has devised a "pervious" parking area that will be 220' x 125' in size. Construction will consist of subsurface Geoweb system to allow for infiltration through stone, with an earthen berm surrounding the parking lot to reduce flow to the adjacent waters. The Geoweb liner will be placed at the +5.1' elevation, with 4" of collapsed Geoweb, capped with 1" stone for a finished elevation of +5.6' msl. NC WRC April 1, 2005 Page 03 Because this type of system is experimental in nature, it must be considered impervious by the DCM for purpose of AEC coverage determinations. The applicant's engineer has evaluated the innovative stormwater system and has determined that the 6155 sf of stone parking within the Estuarine Shoreline AEC will function with an 18% stormwater runoff rate. A weir on the western end of the parking lot will allow for sheet overflow through a 20' x 50' vegetated swale. The existing parking area extends to within 73' of the nhw contour. The western 40' of the proposed parking area will extend to within 30' from the nhw contour, and to 8' at its closest point, resulting in approximately 500 sf of parking area within 30' of the nhw contour line. The vegetated swale will terminate 20' landward of the nhw contour. The expanded parking area will accommodate 39 vehicles, or 50% more than does the existing. 10. ANTICIPATED IMPACTS: The proposal will require the grading of 1.4 acres of high ground, to be surfaced with a Geoweb "pervious" parking area. Impervious area within the Estuarine Shoreline AEC will total 18% based on the innovative stormwater design submitted. Parking for the public ramp will increase from 26 spaces to 39 spaces. Turbidity concerns during construction can be addressed through proper sedimentation/erosion control measures. Approximately 500 sf of the parking area designed as "pervious" will be constructed within 30' of the nhw contour. Use of the facility should not change or volumes increase. Public safety should improve by the elimination of parking on the road shoulders. Tere Barrett April 01, 2005 Morehead City Form DCi1I-ivIP-1 A PPLIC A ra"ff 0 (To be completed by all applicants) 1.

N/A Straits Landing Boating Access Area Applicant or Project Name gnaturc February 4, 2005 Date Narrative for Straits Landing BAA Pervious Parking Lot Proposal Project Description The North Carolina Wildlife Resources Commission (NCWRC) is proposing construction of a new pervious parking area on a 2.56-acre tract of land that provides free public boating access to North River, Back Sound, The Straits, and Core Sound. The proposed location is approximately 6.5 miles from the Atlantic Ocean and 10 miles from the Intracoastal Waterway. The existing facility includes two single lane concrete boat ramps, two fixed docks, one floating dock, a vertical breakwater, two vinyl retaining walls, and a bulkhead along the shoreline. Currently, there is a 140' x 125' (approx) crushed stone parking lot on approximately 1.6 acres of land. Entrance to the access area is directly from SR 1335. The existing parking area was designed to conform to permit requirements, but limited the number of spaces that could be made available to the boating public. Since its opening, the BAA has seen use much greater than planned, which has lead to parking in non-designated areas, to include off site on DOT right-of-way, which presents serious hazards to the public, as they are required to cross a highway to get to the launch area. The NCDENR Division of Water Quality's stormwater regulations require that high density areas (more that 25% impervious) have a best management practice utilized on-site as part of the stormwater plan. An approved stormwater permit has been issued. The attached plats show the layout features that tailor to a more effective means of stormwater control. This narrative proposes a design that will reduce the stormwater runoff by utilizing the entire parking area as a system to allow the stormwater to infiltrate, and increase the number of spaces for additional use. Site Description North River, Back Sound, and Core Sound are classified as SA waters, and portions of Back and Core sounds are further classified as ORW. North River has an average width of 0.7 mile at the location of the proposed ramp, which will be just over 1 mile to Back Sound and approximately 0.5 mile from The Straits. The project site is located on the north side of the Harker's Island Bridge on SR 1335 approximately 4 miles south of Highway 70 via SR1332 near the community of Otway. Current land uses of the project area are as a North Carolina Wildlife Resources Commission Boating Access Area. Current land uses adjacent to the project area include forested areas and private property. Adjacent Property The adjacent property consists of the following: 1. North boundary - Adjacent to landowner Fannie Watson 2. East boundary - NCDOT maintained SR 1335 3. Southwest boundary - North River which is under USACE jurisdiction Soils A Carteret County Soil Survey Field Sheet delineates the project site with Altavista loamy fine sand, which is moderately well drained. Due to the site being previously disturbed and used to store excess soil, several soil profiles have been conducted on the site in the vicinity of the proposed infiltration basin to determine the soil type and permeability rate. A soil infiltration rate of 0.52 inches per hour has been designated as necessary to obtain proper infiltration based on the design storm. The reports determined that the rate is obtainable from design grade to a depth of 16-18" minimum, with a maximum depth to the water table. Copies of the soils reports are included for review. Redevelopment of this access area will not require the clearing of any wooded areas. Wooded areas adjacent to the project site will not be disturbed. No sitework is to be undertaken waterward of the existing bulkhead, and no wetlands are to be impacted. Hydrology The drainage area of the 2.56-acre property has been divided into two sub-drainage areas. This plan will give specific details for each drainage area. The first drainage area is titled "tract 2" on page C-2. It conveys the rainwater through sheet flow to a vegetated buffer with a minimum length of 50'. Per the stormwater permit requirements, this area will require minimal regarding in order to obtain proper flow to the vegetated buffer. The second and larger drainage area, "tract I," is where most of the construction is to take place. Proposed final elevation of the parking lot is 5.6, although through the use of Geoweb and 67 stone, actual soil elevation is 5.2. There is a compacted earth berm around almost the entire site, with an elevation of 6.0, , which allows the entire parking lot to act as a "tub," trapping stormwater and allowing it to infiltrate at a rate of at least 0.52" per hour. There is a weir on the western edge of the parking lot with an elevation of 5.9, so that in the event that rainfall exceeds the infiltration rate, and the "tub" fills, water flows over the weir section and into a vegetated filter Swale. This grassed swale is designed to convey overflow runoff from a rain event in case the infiltration basin is overloaded. The proposed swale has a gentle slope that naturally drains stormwater to a grassed buffer area at the westernmost area of the property, which is at least fifty feet long. Straits Landing Boating Access Area Innovative Stormwater Design Narrative and Calculations Located just before the first Harker's Island bridge, off of SR 1335 in Carteret County, NC, is the Straits Landing Boating Access Area. Existing Development on this site consists of a boat ramp and a small gravel parking lot. This site is located within the White Oak River Basin, with stormwater runoff draining to the North River, stream Class SA. A stormwater management permit has been issued to allow for proposed expansion of the gravel parking lot, which takes the area from a low-density to a high-density category. The overall area of the site is 2.56 Acres, with the Area of Environmental Concern consisting of 0.81 acres, or 35,284 SF. Previously, the impervious area of development within the AEC was 6,155 SF, or 17%. The proposed parking lot, since not recognized as an accepted pervious structure by the Division of Coastal Management, will be classified as impervious for calculating the proposed impervious area. The proposed parking area adds 5,738 SF to the existing, for a total of 11,893SF of impervious area, or 34%. Although DCM requires that only the 4% over the maximum 30% impervious be shown to act as pervious type of proposed structure, the Geoweb parking system, allows for complete infiltration, which will reduce the amount of impervious area to the existing 17%. The parking lot expansion at the BAA is proposed to be a porous parking lot system that will allow stormwater runoff from the first 1.5 inches of rainfall to infiltrate, as required for areas draining to SA waters. However, since an offline bypass in not provided for this system, NCDENR has required a storage volume three times the design storm, or 4.5 inches. This will be accomplished with a porous parking lot system with additional storage located above the surface of the parking lot. The proposed porous system will consist of a product by Presto Products Company called Perforated Geoweb. This product will be filled with 67 Stone (void space -35-45%) that will allow water to infiltrate to the subgrade. It is proposed to replace the existing gravel parking area with this porous system. Another important aspect of the proposed porous parking lot system will be to remove 85% of the total suspended solids (TSS) resulting from the first 1.5 inches of rainfall on the runoff. Referring to the enclosed calculation, since all of the runoff from the first 1. inches of rainfall will be stored within the Geoweb parking system; the TSS removal efficiency will be 100%, assuming the proposed system functions properly.

You provided a map showing fifteen locations where soil borings were to be performed. At the fifteen locations shown on the attached map, which were flagged and approximately located with a GPS receiver, the following were performed: a profile description to seven feet (or as deep as possible with hand augers), measurement of the observed water table, estimated permeability, and estimated hydraulic conductivity. We were unable to estimate depth to seasonal high water table by using low chroma colors on this site due to the varying amounts of fill material present, however, we did note depth to saturated soil on our profile descriptions. If more detailed water table information is needed, we recommend installing monitoring wells in order to measure the actual water table. The purpose of this evaluation was to provide you with additional information for designing a porous parking lot system consisting of 4" Geoweb material filled with stone, over a - subgrade with a minimum estimated hydraulic conductivity of 0.52 inches/hour. The following is a brief report of the methods utilized in this evaluation and the results obtained. Soil/Site Evaluation Fifteen borings were performed across the parking area (borings 1-15), and are shown on the attached map. The depth to the measured water table observed on November 11, 2004 is shown on the profile descriptions, and the soil boring map. The soils varied over the site, however most borings revealed soils consisting of loamy sand and sandy loam fill material surface horizon, which contained dark colored soils with varying amounts of shells, woody debris, etc. These soils contained a clayey Charlotte Office, Greensboro Office: 236 LePhillip Court.

The lower portion of the profile consisted of fine to coarse sand that was saturated in most cases. The soil beneath the fill appeared to be most like the Altavista Soil Series (fine loamy, mixed, thermic Aquic Hapludults) or taxadjuncts of that series. The Altavista Series is typically moderately well drained and formed on low terraces. The soil is strongly acid to medium acid, with low shrink-swell potential. Soil borings 3,4,6,7,8,11,12,13, and 15 all had sandy clay subsurface horizons that have estimated hydraulic conductivities of less than 0.52 inches per hour, and would therefore need to be removed and backfilled with suitable material. Soil Borings 1,2,9, and 10 all had a sandy clay loam layer that has an estimated hydraulic conductivity of. 14 to 1.4 inches/hour. Measurements would be needed to definitively show that these layers are above the 0.52 inches/hour threshold. The permeability estimates are based on the soil texture and are obtained from the USDA-NRCS (United States Department of Agriculture - Natural Resource Conservation Service) "Field Book for Describing and Sampling Soils". No actual site specific testing of hydraulic conductivity was performed. Since the rules require hydraulic conductivity of 0.52"/hr, the permeability estimates were converted to conductivity on the profile description tables. Depending on which location is chosen some clayey layers may have to be removed to meet the 0.52"/hr hydraulic conductivity threshold.. Soil & Environmental Consultants, PA is pleased to be of service in this matter and we look forward to assisting in the successful completion of the project.
