In the space provided below, briefly summarize how the stormwater runoff will be treated. Stormwater will be conveyed via ditches and pipes to an existing wet detention basin on the eastern side of the property. The basin was been designed in accordance with NCDENR criteria for 85% TSS removal. The outflow from the basin drains to an existing level spreader with a 30' engineered filter strip. 2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved: ❑ Approval of a Site Specific Development Plan or PUD Approval Date: ❑ Valid Building Permit Issued Date: ❑ Other: Date: b. If claiming vested rights, identify the regulation(s) the project has been designed in accordance with: ❑ Coastal SW -1995 ® Ph II - Post Construction 3. Stormwater runoff from this project drains to the Yadkin -Pee Dee River basin. 4. Total Property Area: 85.568 acres 5. Total Coastal Wetlands Area: 0 acres 6. Total Surface Water Area: 0 acres 7. Total Property Area (4) - Total Coastal Wetlands Area (5) - Total Surface Water Area (6) = Total Project Area*: 85.568 acres Total project area shall be calculated to exclude the followingR: the normal pool of imppounded structures, the area between the banks of streams and rivers, the area below the Lrmal Higgh Water (N. line or Mean High Water (MHW) line, and coastal wetlands landward from the NHW (or MHW) line. The resultant project area is used to calculate overall percent built upon area (BUA). Non -coastal wetlands landward of the NHW (or MW line may be included in the total project area. 8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 23.10 % 9. How many drainage areas does the project have?l (For high density, count 1 for each proposed engineered stormwater BMP. For low density and other projects, use 1 for the whole property area) 10.

We are applying for a modification to existing stormwater permit SW3100301, originally issued June 2, 2010 for your review and approval. This permit modification is being requested due to an increase of impervious area consisting of a proposed building and paved parking expansion. SITE PLANNING To accommodate the increased impervious area and continue to meet water quality requirements, the outlet structure for the wet detention pond was modified. Enclosed you will find the completed application package as outlined in the transmittal sheet. The modifications to the package (as listed in Section VI. Submittal Requirements) are listed below (with an explanation in italics): • Signed and notarized Deed Restrictions and Protective Covenants Form: not provided, • submitted with initial package • Applicable BMP Supplement Forms and 0&M Agreements: provided only for the wet detention pond; other BMP supplement fonns submitted with initial package • Applicable Soils Report: not provided, • submitted with initial package • Property Deed: not provided; submitted with initial package • USGS Map: not provided; submitted with initial package • Calculations: o Existing Site Data: section omitted; submitted with initial package o Erosion Control Calculations: provided for Skimmer Basins #1 and #2 only, • sediment trap & basins not applicable to Phase 2,• rip -rap apron submitted with initial package o Storm Drainage Calculations: section omitted; submitted with initial package o Pre-Dev Drainage Area Map: section omitted, • submitted with initial package o Composite Drainage Area Maps: section omitted: not applicable to Phase 2 2328 W.

The proposed improvements for the site include a 25,236-sf church expansion additional paved parking areas. The total denuded area for the second phase of the site is 8.79 -acres. Currently, the site is comprised of an existing 20,076-sf church with associated parking, access drives, and stormwater management system. Surrounding the site are fallow agricultural fields with some wooded areas along the northeastern margin of the property. Stormwater for the developed portion of the site is conveyed by inlet structures, piping, and conveyance ditches, which run predominantly from west to east to an existing wet detention pond. Outflow from the existing wet pond goes to an existing splitter box, which discharges a maximum 10 cfs flow to an existing 100' level spreader with a 30' engineered, grassed filter strip (LS-VFS). The larger overflow bypass flows from the splitter box flows through a pipe and discharges near the existing stream. Ultimately, water flows from the on-site stream, beginning at the northeast corner of the site and continues off-site until it reaches Goose Creek. Due to the increased impervious area as part of Phase 2, the existing wet detention pond's outlet structure has been modified to maintain the current detention and water quality performance. The existing wet detention basin was designed to achieve 85% TSS, and was sized to the 1 -year pre minus post condition. The existing downstream splitter box, 100' level spreader, and 30' engineered, grassed filter strip are not being modified for phase 2. Diversion of all off-site flows will continue around the basin and reconnect to pre -developed outflow points along the site margins.

It appears that the Supplement sheet is the correct one because the elevations shown there match the site plan wetpond details. Just email a corrected Narrative sheet and you'll be good to go.
