King, Jr. 110 Wintergreen Road Wilmington, NC 28409 Subject: REQUEST FOR ADDITIONAL INFORMATION Stormwater Project No. SWS 020826 Donnie King Lots (Scotts Hill Bluff) New Hanover County Dear Mr. King: The Wilmington Regional Office received a Stormwater Management Permit Application for Donnie King Lots (Scotts Hill Bluff) on August 26, 2002. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: V 1. Please provide a vicinity map on the plans and show the nearest intersection of I two major roads. A major road is any 1, 2 or 3 digit NC, US or interstate highway. J 2. Please report all built -upon areas in square feet on the application. Small areas are easier to verify in square feet. J3. Please provide your methodology for coming up with the 1.14 acre built -upon area. Based on the permitted 4,414 ft2 of BUA for Lot 23 and 4,480 ftz for Lot 24, the total onsite BUA maximum is 8,894 ft'. Adding this to the 1.07 acres of offsite BUA results in a total of 1.27 acres, not 1.14. The system must be designed for the maximum BUA per lot allowed, not on the;lesser amounts that might actually be built. Please also check the 1.07 acre offsite BUA against the permitted lot maximums per the permit issued for SW8 950112. 4. Please provide a copy of the proposed deed restrictions to include the following conditions and limitations: a. Lot 22R has been required to provide an infiltration basin due to the piping that was constructed across the front of the lot. The system consists of the collection system piping, an entrance swale, an infiltration basin, bypass structure, overflow weir, and 50' vegetated filter. b. The maintenance of the infiltration system is the sole responsibility of the lot owner. Maintenance includes the following items: 1. After every runoff -producing rainfall event, or at least monthly, inspect the collection system, basin, bypass structure and vegetated filter for erosion, trash accumulation, silt accumulation, vegetative cover and general condition. 2. Repair eroded areas immediately, reseed as necessary to maintain adequate cover, mow to maintain a maximum height of 6", remove trash as needed, repair structures as needed and restore the VLNW system to design condition. *A NCDENR N.C.

Remove silt annually, or when the design depth is reduced to 1.9'. Do not overexcavate the system -a 2' separation must be maintained between the Seasonal High Water Table Elevation (1.8 FMSL) and the bottom of the system (permitted at 4.00 FMSL). 4. If the Division of Water Quality determines that the system is failing (evidenced by standing water after 5 days without rain), the lot owner is responsible for repairing it to design condition or providing replacement stormwater management measures in accordance with 15A NCAC 2H.1000. - C. - . The allowable maximum built -upon area assigned to'Lot 22R is 8;894 ftz. - J5. Please have the engineer seal the calculations. J 6. Please delineate the entire 3.74 acre drainage area on a topo map. J 7. The rules require Infiltration systems to be "off-line". All runoff in excess of the 1.5" design storm must bypass the system completely and must pass through a 50' vegetated filter prior to discharge into Futch Creek. Please provide some type of bypass structure with a "smart weir" at the inlet of the basin, provide a 50' vegetated filter (must be on your property) and relocate the emergency spillway so that any overflow from it will pass through the 50' filter before entering surface waters. The road ditch on Futch Creek Road does not qualify as a vegetated filter because it is located on property.owned by the DOT, and you cannot guarantee that it will remain an open ditch. 8. Please show the mean high water line of Futch Creek or any tributaries of Futch Creek on the plans. 9. The 20,364 cubic feet of volume is well overestimated. Per Scheuler's Rv method described in the BMP Manual, the 1.5" design volume would be around 7,250 cubic feet. However, the basin can only accommodate about 4,650 cubic feet. Please revise the application, calculations and supplement'to provide additional volume to accommodate the entire design storm. 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 December 8, 2002, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee. If you need additional time to submit the information, please mail or fax your request for a time extension to the Division at the address and fax number at the bottom of this letter. The request must indicate the date by which you expect to submit the required information. The Division is allowed 90 days from the receipt of a completed application to issue the permit.

King, Jr. Property Scotts Hill Bluff, Section One, Lot 22R Wilmington, North Carolina ESL Project No. 02-111 Dear Mr. Haggett: Thank you for the opportunity to assist you with this project. The results of our study are presented the following report. Introduction Donnie King is planning to construct a private home on the subject site. Regulations require the construction of a collection facility in which stormwater is collected for infiltration into the soil. The purpose of this study was to observe the site soils with respect to their properties influencing permeability to water and the depth to the seasonal high water table (SHWT). Hand auger borings were made on the subject site for the purpose of observing soil conditions to estimate the depth to the SHWT and to estimate the soil permeability. Nine borings were made to depth of 84 inches, or auger refusal, whichever came first. The boring locations are depicted on the attached site map, which was supplied by Haggett Engineering. Observations Borings HA-1 through HA-5 and HA-8 indicate difficult soil conditions for siting a stormwater collection basin or trough. These borings encountered thick layers of sticky, plastic clay soils within the soil profile. As indicated by the presence of gray colors, these Donnie King Property Page 2 clayey soil layers have poor internal drainage. in addition, limestone was encountered at depths of 66 in., 84 in., and 75 in. in borings HA-1, HA-2, and HA-8, respectively. Borings HA-6, HA-7, and HA-9 revealed deep sandy soils with no indication of wetness shallower than about 66 inches (HA-7) and no clayey horizons within 72 inches ((HA-7) of the surface. Conclusions The proposed stormwater infiltration trough should be located in the portion of the subject property where borings HA-6, HA-7, and HA-9 were made. The sandy soil layers observed in these borings are estimated to have a permeability of at least 6 in./hr. Sincerely, C'D W. R.

King, Jr. Property HEA Project 02-1003 Stormwater Management Plan July 15, 2002 Narrative Project Description This project consists in general of the installation of an infiltration basin on a 1.05 acre home site. The site is currently undeveloped and contains approximately nine towards the rear of the site. The piping across the front of the property was installed in accordance with an agreement with the Subdivision developers. Stormwater from the site will drain by sheet flow to the grassed swale on the east side of the site and into the infiltration basin. Additional flow is obtained from upgradient properties and the roadway via the piping system. Flow in the grassed swale is expected to be non -erosive. Site Description The property comprises approximately 1.05 acres that is cleared, but currently undeveloped. Access to the property is obtained off Marsh Field Drive. Based on sandy soils and the size of on -site swales it appears that stormwater run-off is not typically a problem. The site slopes to the northeast at approximately 8%. Area Land Use The property is located in a residential setting with adjacent parcels used for residential purposes. Properties adjacent to U.S. Highway 17 have been converted to various commercial uses. Areas surrounding the site consist of mixed forest with pine and various species of hardwoods represented (oak and gum). Due to the site topography sediment control measures will be placed primarily along the north and east sides of the site in order to minimize the possibility of off -site impact during installation of the basin and swale. Soils The surficial soils at the site are comprised primarily of the Appling series which is characterized as a well drained soil ranging from silty sands to poorly graded sand -gravel mixtures. Soil conditioners and fertilizers are typically required to maintain vegetation. The surface layer is typically a light silty sand approximately 6-inches thick. Permeability in the surface layer is moderately rapid and becomes rapid in subsequent layers. Available water capacity is typically medium and shrink swell potential is low. The maximum non -erosive velocity for unprotected soils is 2.5 fps. Proposed Sediment and Erosion Control Measures Silt Fence Silt fence will be installed along the north and east property lines in proximity to the basin and swale to control sediment that may be transported by sheet flow run-off. Page 1 Donnie F. King, Jr. Property HEA Project 02-1003 Stormwater Management Plan July 15, 2002 Seeding/Mulching Disturbed areas will be stabilized as soon as practical after reaching final grade of the area and following approval of the Owner. Temporary seeding will be provided to disturbed areas if the area will not be actively graded for an extended period. Seeding and mulching specifications are provided on drawing C-2. Disturbed areas will be stabilized within 15-days after reaching final grade. All clearing and grading will be planned and conducted to minimize the duration of exposure of unprotected soils. Page 2 Donnie F. King, Jr. Property Stormwater Management Plan HEA Project 02-I003 July 15, 2002 Construction Sequence & Schedule 1) Obtain plan approval for stormwater management plan. 2) Obtain other applicable permits. 3) Layout excavation limits for basin and swale and locations for control measures. 4) Conduct pre -construction conference at site to review control measures and sequence of construction. 5) Install silt fence to prevent sediment from leaving the site to the north or east. 6) Protect trees and other vegetation to remain on -site. Grade basin and swale in accordance with approved plan. No other site grading is required. 7) Stabilize disturbed areas using seed, fertilizer and mulch after completing land disturbing activities. Stabilize areas within 15 days to minimize sediment loading to infiltration basin. 8) Inspect all control measures and seeded areas weekly at a minimum. Inspect after each rainfall event. Make timely repairs as needed. Provide additional measures if erosion is evident or if requested by DENR. 9) Remove temporary measures only after vegetation is well established and site is stabilized. Remove sediment that accumulates in the infiltration basin. 10) Estimated time for site soils to be disturbed is 2 weeks. Page 3 Donnie F. King, Jr. Property HEA Project 02-1003 Stormwater Management Plan July 15, 2002 Maintenance Plan 1 } All control measures and seeded areas will be inspected after each run-off producing rainfall event and a minimum of once per week. 2) Seeded areas will be re -seeded, watered, and soil amendments added as necessary to promote growth of the vegetative cover. 3) Sediment will be removed from behind silt fences when it becomes approximately 6- inches deep. Silt fence fabric, post, and wire will be repaired as necessary. 5) Remove sediment from the infiltration basin after the site has been stabilized, but prior to installing the permanent vegetation in the basin.
