The property is located at 4301 Market Street. There is an existing McDonald's restaurant that occupies this current: location. 1'he proposed construction will consist of total demolition of the existing restaurant and parking and construct a single-story 6,358 square foot building with curb islands, associated parking, a storm water detention/water quality facility. In section II of this document we will discuss storm water detention/water quality for this site. The runoff from this site will either be collected by a storm drainage system or will sheet flow through the parking areas to where it will either discharge into the proposed detention/water quality facility. See the appendices for supporting calculations. Section III of this document: addresses water quality. Per NCDENR, wager cluality must be provided for the entire site. Refer to section III and appendices for supporting information. I.-) EXISTING SITE CONDITIONS The existing site consists of a McDonald's building and associated parking. Access to the Proposed site will be granted from IMarket Street. 1.3 ADJACENT AREAS The site fronts onto Market Street which bounds the site to the south. 'Fhc adjacent lot to the north is vacant. 'Travel Inn motel is located on the lot to the cast and a Quick Lube exists on the lot to the west. 1.4 CRITICAL EROSION AREAS The most critical erosion area will be the surface of the working area during construction operations. If grass is not established on dormant denuded areas then there is a significant potential for the covered areas to be eroded and for sediment to be carried in the runoff. 'Po minimize the potential for erosion, covered areas that:are temporarily inactive will be seeded within 14 working days after placement of the soil corer. 1.5 EROSION AND SEDIID,IENT CONTROL D4E.-\SURES All vegetative practices and erosion and sediment: control features shall be designed, constructed and maintained in accordance with the North Carolina Erosion and Sediment Control Planning and City of Wilmington Standards and Specifications.

Supporting design calculations are attached. Plan-view drawings with details arc also provided. 1.5.1 Stabilized Construction 11,n trance/Exit (Reference NCE'SCPllM STD & SPI_:C 6.06) Stabilized construction entrances should be used at all points where traffic will be leaving a construction site and moving directly onto a public road. Wash down facilities may be required as directed by your local approving agency. Construction entrances should be used in conjunction with the stabilization of construction roads to reduce the amount of mud picked up by vehicles. 1.5.2 Silt Fence (Reference NCESCPDM STD & SPEC 6.62) Sediment fences will be provided down gradient of the proposed site grading at the locations shown on the drawings. The sediment fences will direct flow to either a sediment deposition area behind the fence or to a sediment trap. Silt fences are not to be used across channels or in areas of concentrated flows. 1.5.3 Drainage Swale (Reference NCESCPDil1 STD & SPEC) Diversion ditches will be utilized to direct overland flow to appropriate sediment and erosion control devices. 1.6 VEGETATI TF STABMZATTON Vegetative cover shall be re-established within 15 working days or 30 calendar days after completion of the activity, whichever period is shorter. 1.7 TEMPORARY STABILIZATION Disturbed areas will be vegetated in accordance with section 3.0 of the Norlh Carolina Erosion and Sedimenlalion Control Des;gn tblanual and the seeding specifications. Tel control features will remain in place and will be maintained until the up-gradient disturbed area has been stabilized with vegetative cover. 1.8 \1AINTENANCE All erosion and sediment: control measures will be checked for stability and operation following every runoff-producing rainfall but in no case less than once even week. Any needed repairs will be made immediately to maintain all measures as designed. The sediment basin shall be inspected regularly during land disturbing activities and after each runoff producing rainfall. Sediment shall be removed and the basin restored to its original dimensions when sediment has accumulated to one-half the design depth of cacti SW-NI Report M Donald's—\\ilnungton, NC Febtvan•26,2007 \YICD-NeDondds\U518-WiLninAnon �Ci_/A16A0gsen yVAICDn> &S0.11 FeparzOb'b-O)doc �� •^;r'� basin. Portions of the basin's gravel facing that: are contaminated be sediment shall be replaced with fresh gravel during each sediment removal episode. Sediment fences shall be inspected at least once a meek and after each rainfall. Repairs shall be made immediately. Sediment deposits shall be removed as needed to provide adequate storage volume for the nest rainfall event, and to reduce pressure on the fence. Fencing materials and sediment deposits shall be removed, and the area brought to grade following stabilization of up gradient disturbed areas. 1.9 CONSTRUCTION SEQUENCE 1. Construct entrance pad. 2.

Runoff coefficients that were use were 0.95 for impervious area and 0.2 for grass areas. . Pond routing calculations were completed using the Chainsaw method. Detailed routing results are located in the appendices of this report. Storm pipe calculations for the run of pipes leading to the infiltration/detention basin were conducted with StormCAD modeling software. Detailed model results are located in Appendix G of this report. The results show that the 10-yr stone is contained in the pipe/inlet system. In the 50-yr storm, the two upstream-most structures will flood; however, overflow stormwater would be contained on the site parking area. 2.2 SUMA,fARY OF RESULT'S PRE-EXISTING SUMMARY 10 0.20 720 1.39 2.02 50 0.20 8.89 1.39 2.49 POST-DEVELOPMENT SUATALIRY 10 0.73 7.20 1.39 1.67 50 0.73 8.89 1.39 6.04 SWIM Report ;1 McDonald's—Wilnungton, NC s; ,i February 26 20O7 54, -.\MCD \McDonald 018-RSLnmoov NCID0016\Engmwdng,MCW518-S0..\1 Hcp ,1L2-260]doc 6 k, ww*w 2.3 CONCLUSION Storm water will be detained in the proposed detention pond and will reduce post development flows to less than prc- developed conditions for the 10-year storm. SECTION III —WATER QUALITY The pollutant removal design standard of 85% removal of total suspended solids will be met by use of an earthen infiltration basin. Stormwater from the site will be routed into the infiltration basin. Stormwater from the first 1 inch of rainfall will infiltrate into the soil. The earthen infiltration basin will be constructed on site, and also used for stormwater detention (see previous section). Infiltration tests conducted'at the proposed infiltration basin location on the site indicated an infiltration rate of approximately 16.6 inches per hour (see report included in the Appendix). Based on the determination of Vincent Lewis of the Division of Water Quality, the seasonal high water table is such that there will be a separation of approximately 2 feet between the seasonal high water table and the bottom of the proposed infiltration basin. The infiltration basin is designed to capture and infiltrate, at a minimum, the runoff from the First l inch of rainfall. Stormwater will flow across parking areas, into inlet structures or concrete flumes, and into the basin. Runoff in excess of the design volume of the basin will flow over a weir into discharge piping, and flow through a 30-foot vegetated buffer prior to entering the existing roadside stormwater drainage system. Maintenance 1. After every runoff producing rainfall event and at least monthly, inspect the infiltration/overflow/bypass structures for blockage and deterioration and the infiltration basin structure and system for erosion, trash accumulation, grass cover, and general condition. 2. Repair eroded areas immediately, re-seed as necessary to maintain adequate vegetative cover, mow vegetative cover to maintain a maximum height of six inches, and remove trash and blockages as needed to maintain system performance. 3. Remove accumulated sediment annually or when sediment depth fills the sump in the control manhole. Restore sump depth to original design depth.

Form SNU-103 Rev _i.99 Paee 2 of 3 IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT I. After evcry runoff producing rainfall event and at least monthly inspect the infiltration system for erosion, wash accumulation, vecuctative cover, and general condition. 2. Repair eroded areas immediately, re-seed as necessary to maintain adequate vegetative cover, mow vegetated cover to maintain a maximum height of six inches, and remove trash as needed. 3. .After every runoff producing rainfall event and at least monthly inspect the bypass, inflow and overflow structures for blockage and deterioration. Remove any blockage and repair the structure to approved design specifications. 4. Remove accumulated sediment from the pretreatment system and infiltration basin annually or when depth in the pretreatment unit is reduced to 75% of the original design depth. The system shall be restored to the original design depth without over-excavating. Over-excavating may cause the required water table separation to be reduced and may compromise the ability of the system to perform as designed. Removed sediment shall be disposed of in an appropriate manner and shall not be handled in a manner that will adversely impact water quality (i.e. stockpiling near a stormwater treatment device or stream, etc.). A benchmark shall be established in the pretreatment unit. The benchmark will document the original design depth so that accurate sedirent accumulation readings can be taken. The measuring device used to determine the depth at the benchmark shall be such that it will give an accurate depth reading and not readily penetrate into accumulated sediments. When the design depth reads — ment unit and the infiltration basin. 5. If the Division determines that the system is failing, the system will immediately be repaired to original design specifications. If the system cannot be repaired to perform its design function, other stormwater control devices as allowed by NCAC 21-1 .1000 must be designed, approved and constructed. I acknowledge and agree by my signature below that t am responsible for the performance of the five maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to any changes to the system or responsible party.

This letter, with attachments, is the report of our evaluation. Field Investigations On September H, 2006, FCS conducted an exploration of the subsurface soil and ground water conditions at two requested locations shown on the attached Site Diagram. The purpose of this exploration was to obtain subsurface information of the suitability of the in-place soils for the proposed infiltration area. We explored the subsurface soil and ground water conditions by advancing one hand auger boring into the existing ground surface at the two requested boring locations. We visually classified the subsurface soils and obtained representative samples of each soil type encountered. We also recorded the ground water level.observed at the time of the hand auger boring. The attached Infiltration Evaluation Form provides a summary of the subsurface conditions encountered at each hand auger boring location. Ground water was encountered during our exploration at both test locations at a depth of 36 inches below the existing grade elevation. The seasonal high ground water level (SHWI,) was estimated to be at a depth of 30 inches for test location one and 24 inches for test location two below the existing grade elevation. We have conducted two infiltration tests near our hand auger borings to estimate the infiltration rate for the subsurface soils. The infiltration tests were conducted at two feet above the SrIWL for both requested locations. 7211 Ogden Business Park ^Suite 201 1 Wilmington, NC 28411 °(910)686-9114 •Fax (910)686-9666 Fran: 09/14/2006 09: 18 3826 P. 003/005 Infiltration Evaluation McDonald's Wilmington,North Carolina ECS Project No.22.12427 Field Test Results At the first requested test location, the infiltration test was performed at 10 inches in grey fine SAND and indicated an infiltration rate of 0.28 inches per minute(16.6 inches per hour). At the second requested test location, the infiltration test was performed at 10 inches in grey fine SAND and indicated an infiltration rate of 0.29 inches per minute(17.4 inches per hour). Infiltration rates may vary within the proposed site due to possible changes in subsurface conditions. If you have any questions regarding this report, please contact us at(910) 686-9114.

I certainly support this resolution and will provide quick permitting service through the Express Permitting Program. The original reviewer will be available to review it during the week of February 26. He will be on vacation the following week. Please submit the request for permit modification including a check for $4,000 and all supporting information to the Wilmington Regional Office as soon as possible so we can accommodate the needs of the permittee.

As parking spaces were removed to protect the tree. Elevations did NOT change. We would prefer the$1 k express change option. Will this be acceptable given the above? Brian T. Soltz .

If the site modification results in no significant change to the Stormwater infiltration system, meaning that there is no decrease in volume and the elevations have not changed, then the modified plans can be submitted and it can be approved as a "Plan Revision". For this service there is no fee through the regular program and a $1,000 fee for Express permitting service. If the resulting volume and elevations are changed then the permit will need to be modified, requiring associated submittals and fees: Please let me or Cameron know if additional information is needed.
