Probably the easiest was to do this is to dimension the DA by utilizing and expanding on the DA dimensions already provided along the property boundary -- the DA is relatively angular and should not be too difficult to dimension. 3. The DA map does not appear to be entirely supported by the contour information provided. Specifically: o The elevations shown for the S & SW portion of the new gravel area do not clearly show all of that runoff will drain to the SD system and into the pond. Some runoff may flow into the new SD that bypasses the pond. o There is no contour information provided around the new parking area at the SW portion of the project area — no way to verify DA. o The spot elevations around the maintenance facility appear to.show the DA along the edge of the facility o There is nothing to show offsite runoff does not enter the site. **PHIL** - Clearly, you drew the DA where you did for a reason; if you have spot elevations to support the above concerns, please put them on the drawings. I will make a field visit either today or Monday to verify the DA on the existing portions of the site — this will likely clear up the last 3 bullets. If you obtained the DA via field verification, please add a note to the drawing indicating that. Because the gravel parking area is going to change from existing (however slightly) I cannot field verify the first bullet. NORRIS, KUSKE & TUNSTALL John S. Tunstall, P.E. J. Phillip Norris, P.E.

A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review. 1. Gary R. Nunnelee is the only ManageF listed with the Secretary of States office as being affiliated with Nunnelee Properties,"LLC.�Tuney Nunnelee is not listed. Please have Gary Nunnelee sign the application or provide documentation that Tuney Nunnelee is a Manager. / 2. Please dimension all proposed BUA 'within the drainage area. 3. It is very difficult to tell what is proposed vs. existing -and pervious vs. impervious. Please clarify. Also, the drainage area was designed for 100% impervious. Is what is currently proposed within the drainage area,1�00% impervious? There appears to be at least a few areas that are pervious (lands'cape islands) within the drainage area. If the system was simply designed at 1006/76impervious but is currently proposing less, please indicate this on the application. 4. Please include the amount of existing impervious area within the proposed pond drainage area on Section ill (6) of the application (only the portion that is to remain). 5. Provide some roof drain detail to show roof drains will direct runoff within the permitted drainage area to the pond. 6. Please add a North arrowtothe drawing. 7. Please add a note indicating there are no wetlands present on the site (or show them if they do exist). Please note that this request for additional information is in response to a preliminary review. The requested information should be received by this Office prior to May 2, 2006, or the application will be returned as incomplete.

Box 10159 Wilmington, NC 28404 (910) 799-3011 March 2006 Prepared by: NORRIS, KUSKE & TUNSTALL CONSULTING ENGINEERS, INC_ 902 Market Street Wilmington, North Carolina 28401 (910) 343-9653 (910) 343-9604 (Fax) E-mail: office@nkteng.com NKT Project No_ 05113 03/15/2006 WED 12:49 FAX 910 343 9604 Norris, Usk, 'Nnstall cuuvun NARRATIVE DESCRIPTION: The project site is a developed tract located off of Harley Road in Wilmington, North Carolina. The soils of the site consist of lightly vegetated, sandy clay topsoil and grades ranging from 0.5% to 2.0%. Approximately 3.0 acres will be graded to allow construction of a new building addition with paved parking and paved access. The runoff from the site is estimated using the rational method 10-year and 25-year design storm and rainfall data for the area. Construction is scheduled to begin as soon as all permits and approvals are obtained. EROSION CONTROL MEASURES: The attached plans and specifications outline the requirements for erosion control measures. Silt fencing will be provided along each side of the entrance drive where stormwater would be expected to sheet flow from disturbed areas directly to adjacent property. The detention pond will be used as a silt basin during construction and restored to its design contours prior to completion. A gravel construction entrance will be constructed at the main entrance. Maintenance will be provided by the grading contractor and developer. STORMWATER MANAGEMENT MEASURES: The project site is located in New Hanover County. Land disturbing on the site will exceed one acre; which requires the site to comply with the State .Regulations. The stormwater runoff from the development will be directed to the proposed stormwater detention pond_ CONSTRUCTION SEQUENCE: The Contractor will install the gravel construction entrance and sift fence prior to beginning any clearing and grading operations. Additional silt fence will be installed when and if conditions warrant during construction. The detention pond/silt basin will be constructed immediately after that portion of the site is cleared, and outlet structure with protection will be installed. Disturbed areas will be landscaped or seeded upon completion_ EROSION CONTROL NOTES AND MAINTENANCE PLAN Install erosion control measures before beginning construction or as .soon thereafter as possible. All erosion and sediment control practices will be checked for stability and operation following every runoff -producing rainfall but in no case less than once every week. Any needed repairs will be made immediately to maintain all practices as designed. 2. - Maintain the gravel construction entrances in a condition to prevent mud or sediment from leaving the construction site. The contractor shall inspect the construction entrances on a daily basis. This will require periodic top dressing with additional No. 4 stone. Any objectionable materials spilled, washed, or tracked onto public roadways shall be removed immediately. 3. Install erosion control measures around the drop inlets as shown on the plans to trap silt during construction. Inspect the erosion control around the inlets after each rain and make repairs immediately. Remove sediment when it becomes 0.50 deep to provide adequate storage volume for subsequent rains. When the contributing drainage area has been adequately stabilized, remove all materials and any unstable soil and either salvage or dispose of it properly. Bring the disturbed area to proper grade and appropriately stabilize all bare areas around the drop inlets: 4. Sediment will be removed from behind the silt fence when it becomes 0.5 feet deep at the fence. ' The sediment fence will be repaired as necessary to maintain a barrier. Silt fence stakes shall be spaced 6 feet apart unless a wire backing is used with 8 foot stake spacing. 5. Inspect temporary sediment traps / check dams after each period of significant rainfall. Remove sediment and restore the trap to its original dimensions when the sediment has accumulated to one-half the design depth of the trap. Place the sediment that is removed in the designated disposal area and replace the contaminated part of the gravel facing. Check the structure for damage from erosion or piping. Periodically check the depth of the spillway to ensure it is a minimum of 1.5 ft below the low point of the embankment. Immediately fill any settlement of the embankment to slightly above design grade. Any riprap displaced from the spillway must be replaced immediately. After all sediment - producing areas have been permanently stabilized, remove the structure and all unstable sediment. Smooth the area to blend with the adjoining areas and stabilize properly_ 6. The stormwater ponds will act as sediment basins and will be cleaned out when the level of sediment reaches 2.0 ft below the top of the riser. Gravel will be cleaned or replaced when the sediment pool no longer drains properly_ 03/15/2006 WED 12:50 FAX 91U 343 W4 Morris, husKe, itinstan C' UUJ! VVJ 7. The angle for graded slopes and filis shall be no greater than the angle that can be retained by vegetative cover or other adequate erosion -control devices or structures. In any event, slopes left exposed will, within 21 calendar days of completion of any phase of grading, be planted or otherwise provided with temporary or permanent ground cover, devices, or structures sufficient to restrain erosion. 8. All disturbed areas shall be seeded within 15 days of disturbance. All seeded areas will be fertilized, reseeded as necessary and mulched according to specifications in the vegetative plan to maintain a vigorous, dense vegetative cover. 9. More stringent measures shall be used to halt erosion if those shown on this plan are -not effective. 10_ All erosion shall be controlled including side slopes before the project is completed. 11. Remove temporary measures upon completion of project. All permanent measures will be well established before project closeout. I SECTION 02920 SOIL EROSION AND SEDIMENTATION CONTROL 1.
