1 The Forebay Volume was previously submitted as 40,700 cu ft The corrected value is 48,700 cu ft The 1' page of the Wet Detention Basin Supplement for Stormwater Pond - 1 has been updated The other permits and supplements that were previously submitted are correct The revised supplemental calculations and wet detention basin supplement page have been attached with this response Than u, Jay Carmine, E I 150 01 NCDENR DWQ RFI Response 032106 doc Page 1 of 1 I- % P 1 * * * COMMUNICATION RESULT REPORT ( MAR 17 2006 FILE MODE OPTION --------------------------- 548 MEMORY TX ADDRESS (GROUP) --------------- 92540502 5 11PM ) * * * TTI NCDENR WIRO RESULT PAGE -------------------------- OK P 2/2 REASON FOR ERROR E-1) HANG UP OR LINE FAIL E-2) BUSY E-3) NO ANSWER E-4) NO FACSIMILE CONNECTION State of North Carolina Department of Environment and Natural Resources Wilmington Regional Office Michael F Easley, Governor FAX COVER SHEET William G Ross, Jr, Secretary Date: 3/17/06 No of Pages; 2 (Incl Cover) To Jeff Petroff From, Paul Bartlett Company.

Narrative Protect Description This stormwater design is for the high density residential development of approximately 42 4 acres off of Southport Supply Road (N C Highway 211) in the Lockwood Folly Township of Brunswick County, North Carolina (see vicinity map on plan set) The overall site will be treated by three (3) wet detention basins Stormwater will be collected by valley curb and gutter and catch basins These stormwater ponds will allow the project to meet the NCDENR stormwater requirements as well as Brunswick County's Pre -Post requirements Site Description The predominant topography has significant relief with slopes ranging from 2 to 5% towards an unnamed tributary to the Lockwood Folly River This receiving body of water is classified as a SC waterway The elevations of this project ranges from 22 feet MSL to 44 feet MSL The major soil in the areas is primarily Blanton sands which is a very well draining soils Other soils on this site are Foreston loamy fine sand, Baymeade fine sands, Leon fine sands, Madarin fine sands, and Rains fine sandy loam The surrounding properties are mainly rural -residential The project is adjacent to Palmetto Creek of the Carolinas Wet Detention Basins The wet detention basins on this site are designed as conventional stormwater ponds Please see the attached plan The minimum riser elevation for each pond (permanent pool elevation) was set according to the Tom Scheuler method using the first 1" of capture With the 1" storage elevation set as a minimum, all three (3) risers were adjusted for more storage to meet the Brunswick County Pre -Post requirements The ponds were modeled using "Hydraflow-Hydragragh" modeling software Each pond is capable of storing the 50 year — 24 hour storm event with only orifice discharging with stormwater ponds 1 and 2 capable of storing the 100 year — 24 hour storm without discharging The principal riser for each pond is designed to carry the 10 year storm event An emergency spillway has been designed at a weir elevation which will accommodate the 25-year storm event coastal Land Design, PLLC C n J Fngimeennl, / I an&wpL Archrtcetnie / Comtrmbon Ntanagwmurt P O
