Taft, Sr., Manager Street Address. 2217 Stantonsburg Road Greenville, NC 27834 Mailing Address: P.O. Box566 Greenville, NC 27835 (252) 752-7101 Engineer: Stroud Engineering, P.A. 151-A Highway 24 Morehead City, NC 28557 (252) 247-7479 License Number: C-0647 I. General Information Compass Landing Apartment Homes located off Old Fashion Way in Newport, Carteret County is a 22.1 acre tract. The wetlands have been delineated and approved by the U.S. Army Corps of Engineers (please see attached wetlands plat). This tract is being proposed as a three hundred and twelve (312) unit multi -family apartment project associated parking, club house and pool. There are thirteen (13) three-story building each with twenty-four (24) units. The project is to be serviced by the Town of Newport for both water and sewer. Access to the project via state or town roads, therefore construction across other property is not necessary or proposed. The modification includes redesign of the wet detention pond and routing of pipes discharging into the pond. The wetland to the east of the permitted pond has been determined as an isolated wetland, therefore allowing 1/3 of an acre of impact without written concurrence from DWQ. The pond has been enlarged and the vinyl retaining walls removed. MAR 2 8 2011 r. II. Stormwater Information The project is located within the White Oak River basin and currently drams westerly to Shoe Branch Class C, 21-6, a tributary of the Newport River. This project is being submitted as a high density residential commercial project under the current Coastal Stormwater Rules. Stormwater will be treated by a wet detention pond to 90% TSS. III. Erosion and Sedimentation Control Measures The following measures are proposed for the site. If it becomes evident that additional erosion and sedimentation 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. 1. Sediment Fence - Sediment fence will be utilized as necessary in locations as shown on plans or as deemed necessary by the engineer to insure 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. Stone Construction Entrance - Stone construction entrance will be used to reduce transport of sediment off site. 4. Sediment Basins- The detention pond to be constructed will serve as a sediment basin during construction. This project requires a storage sediment rate at 3600 cf/acre of disturbance and required surface area is based on the 10-year storm. Sediment volume from the earth disturbing activities draining to the pond is estimated to be 68,400 cubic feet based on 19.0 acres of disturbance. The forebay will have 24,527 cf and the main basin 129,880 cf of sediment storage capability totaling 154,508 cf exceeding the required volume. The surface area required of 18,142 sf is also exceeded providing a total surface area of 24,550 sf. Upon completion and stabilization of project the pond shall be cleaned to the original design depth. IV. Maintenance Plan 1. All erosion and sediment control measures shall be checked for stability and effective operations following every runoff producing rainfall event or at least once per week. Repairs required shall be completed immediately to the dimension and functions indicated on the plans. 2. Sediment shall be removed form behind the sediment fencing when it becomes 0.5 feet deep at the fence. The fence shall be replaced or repaired as necessary to maintain a barrier. 7TC-j :-'VED MAR 2 8 2011 3. All seeded areas shall be fertilized, seeded and mulched within 14 calendar days of disturbance. Disturbed areas shall be fertilized, reseeded and mulched as necessary according to the Contract documents to establish and maintain a dense vegetative cover. V. Construction Sequence 1. Remove and/or relocate existing obstructions. 2. Install gravel construction entrance and silt fencing at specified locations. 3. Complete clearing and grubbing operations. 4. Excavate, rough grade and temporarily see stormwater detention basin. 5. Rough grade parking areas and begin preparation of building sites. 6. Seed and mulch all areas of disturbance not to be paved within 14 days of land disturbance. 7. Install drop inlets and storm drainage piping with sedimentation control measures. 8. Install utilities. 9. Fine grade drive and parking area and place stone base course. 10. Construct buildings. 11. Pave drive and parking areas. 12. Perform final grading, see and mulch all remaining disturbed areas. 13. Remove accumulated sediment from stormwater detention basin and perform final grading of basin. 14. Install wet detention basin vegetation as specified on pond landscaping plan. VI. Design Assumptions 1. Design storm is ten years for both culvert design and sediment control. 2. The rational method was used for the design.

General Information Compass Landing Apartment Homes located off Old Fashion Way in Newport, Carteret County is a 22.1 acre tract. The wetlands have been delineated and approved by the U.S. Army Corps of Engineers (please see attached wetlands plat). This tract is being proposed as a three hundred and twelve (312) unit multi -family apartment project associated parking, club house and pool. There are thirteen (13) three-story building each with twenty-four (24) units The project is to be serviced by the Town of Newport for both water and sewer Access to the project via state or town roads, therefore construction across other property is not necessary or proposed The modification includes redesign of the wet detention pond and routing of pipes discharging into the pond. The wetland to the east of the permitted pond has been determined as an isolated wetland, therefore allowing 1/3 of an acre of impact without written concurrence from DWQ. The pond has been enlarged and the vinyl retaining walls removed. VFD MAR 1 6 2011 3Y: -.7 -J' 2 4.
