Tract located at 101 Salter Path Rd, west Atlantic Beach area, Morehead Township, Carteret County, North Carolina. TO: Pine Knoll Shores Hotel Mr. Fred Bunn FMB, Inc. 2207 West Nash Street Wilson, NC 27893 (919) 291-9000 Mr. Ron Cullipher, PE Stroud. Engineering Company, PA 151-A NC Hwy 24W, Hestron Plaza II -A Morehead City, NC 28557 (252) 247-7479 The land & soils of the Pine Knoll Shores Hotel Tract (-2.3 acres) were evaluated and mapped to determine general usability for on -site, subsurface waste treatment. The rules & regs of NCGS 130-A and NCDENR-DHS NCAC T15A:18A-.1900 were used as guidelines in this evaluation. This evaluation and mapping were completed through transecting the geomorphic landscape positions, free soil survey techniques, and aerial photo interpretations. Soil borings/probes were made from the present ground surface to -120" depths to verify soil compositions and characteristics. Soil characteristics were grouped into soil map units that will function in a similar manner for spray irrigation usage. The resulting land & soils map shows the locations of the respective soil map units. The tract is located on the maritime barrier island of Bogue Banks adjacent to the Atlantic Ocean, with typical ridge/slough landscape postions. Elevations range from sea level (0 ft amsl) to -20 ft amsl, with the the area for future waste treatment usage between 13-15 ft (amsl). A major portion of the tract has been historically (<1975) cut & filled based upon 1975 aerial photos, with the higher sandy dunes having been cut -down to fill lower elevations landscape positions. These lower elevations appear to have natural soils (Leon and Corolla) that are somewhat poorly to moderately well drained, and now have 1-6 ft of sandy historic fill over them. - The enclosed land & soils map shows the various classifications of lands as to waste treatment suitability and their relative locations. The following is a brief description of each land & soil classification: The "GREEN" Soil Areas (see map) are relatively undisturbed sandy soils. These soils have deep +120" fine to medium sand textures. The soils are excessively well drained with an estimated seasonal high static water table 100 -180" from the soil surface or at -5-6 ft elevations, based upon soil wetness indicators and relative elevation levels. Estimated permeability to <2-5 min/in (+12-30 inlhr) to +120" depths, based upon soil texture and structure. Present surface elevations range from -15 - 20 ft amsl. Soil types found are Newhan. These sites should have Page 1 of 2 few limitations for waste treatment or stormwater usage, except for normal buffer set -backs and contouring of slope areas to provide a relative uniform site. The "BROWN' Soil Areas (see map) are historically (<1974) cut -down and excavated areas. These were former sand dunes and sideslopes that have been excavated down -1-6 ft so that they are relatively level areas.ed sandy soils. These soils have deep +120" fine to medium sand textures. The soils are excessively well drained with an estimated seasonal high static water table +105 - 120" from the soil surface or at -5-6 ft elevations, based upon soil wetness indicators and relative elevation levels. Estimated permeability to <2-5 min/in (+12-30 in/hr) to +120" depths, based upon soil texture and structure. Present surface elevations range from -13.5 -15 ft amsl. Soil types found are Newhan-Cut phase. These sites should have few limitations for waste treatment or stormwater usage, except for normal buffer set -backs. The "YELLOW" Soil Areas (see map) are historically (<1974) cut & filled areas. These were former lower sideslope and dry -slough areas that have been filled +1-6.5 ft so that they are now relatively level to adjacent cuttexcavated areas from where the sandy fill materials were borrowed. These soil areas appear to be deep +120" fine to medium sand textures, with no debris or significant shell content. The soils are excessively well drained with an estimated seasonal high static water table +90 -100" from the soil surface or at -5-6 ft elevations, based upon soil wetness indicators and relative elevation levels. Estimated permeability to <2-5 min/in (+12-30 in/hr) to +120" depths, based upon soil texture and structure. Present surface elevations range from -13 - 14.5 ft amsl. Soil types found are Historic Sandy Fill over natural soils of Corolla and Leon -dry non-restrictive phase. The buried natural soils appear to have a seasonal high static water table 12-35" from their natural surfaces. These sites should have few limitations for waste treatment or stormwater usage. NCDENR-DHS rule (.1957-b-2-E) only allows a maximum of 480 gal/day flow into historic fill that meets the historic fill rule criteria, but the underlying natural soils appear be usable for new fill system (.1957-b-1). 1n addition, rule .1957-b-3 allows for other fill systems to be approved on a site specific bases in accordance with rule .1948-d. Addition site testing is usually required to characterize and quantify the soil/site parametersfor large (+1500 gal/day/field or +3000 gal/day/system) subsurface waste treatment systems. This is a preliminary and qualitative land & soils evaluation of this tract for subsurface waste treatment or stormwater usage. This report and map should be used for planning purposes only. Final permitting is subject to NCDENR-DHS and/or other regulatory agency applications, reviews, and approvals. The respective agencies should be contacted before initiating any construction or investing significant time and monies.

',Description of Project ype-of Development'. The proposed project is for the construction of eight, three bedroom condominiums. The project is located at 101 Salter Path Road, in Pine Knoll Shores, Carteret County, North Carolina. The project is to be developed in accordance with the approved plans -and specifications for the construction of .streets and drainage improvements. 2. Earth Disturbing Activities a Excavation -and grading.for the,installation of roads and drainage improvements. 3. 'Drainage The site presently does not drain offsite. Water stays on site and infiltrates into the ground. The proposed plan is for parking and drive are to drain to drop inlets and then infiltrate into the ground through 36" perforated corrugated plastic pipe. The drainage for the buildings is to'be diverted to the area behind the buildings to infiltrate into the ground. B. Erosion and Sediment Control Measures Various levels of erosion control are proposed on the plan. If it becomes evident that additional erosion and sediment control measures are needed, they shall be installed immediately. It is intended that all grading and excavation activities within a certain area will be protected. as soon as that activity is complete. l . ' Silt Fence — Silt fence will be ,utilized as necessary in location shown on the plans or as deemed necessary by the engineer to ensure that off -site sedimentation is controlled. 2. Seeding — All disturbed areas will be seeded within 14 days following construction in accordance with the seeding schedule shown on the plans. 3. Sediment traps.. C... Time Sequence of Operation 1. Obtain Plan approval and any other necessary permits. 2. Initiate clearing and grubbing operations in applicable areas. 3. Install temporary stone construction entrance. 4. Complete clearing and grubbing operations. 5. Install silt fence at location shown on plans. 6. Construct infiltration system. 7. Rough grade site. 8. Install subsurface utilities & drainage features, construct building 9. Construct parking Iot and drive. 10. Seed all area not to be paved within l4days of land disturbance. 11. -Pave parking lot and drive. 12. After site is stabilized, remove remaining temporary measures and install permanent vegetation on disturbed areas. D. Design Assumption 1. Design storm is ten years 2. The rational method was used for design. E. Coastal Stormwater Regulations -The North Carolina Division of Environmental Management implemented coastal stormwater regulation in coastal counties on January 1, 1988. These regulations are detailed in 15 NCAC 214.1000 Stormwater Runoff Disposal, These rules allow for a development to consider density options as a passive means to reduce water quality impact.
