As there was only one comment, which he acknowledged required a plan revision, we were awaiting receipt of the revised plans. However, to assist you in responding to permit status questions we offer this review letter. The following items require plan revision: 1) The swale on the north side of the lot has swale inverts higher than the existing R.O.W. shoulder. The swale should be lowered. 2) Clean the roadside shoulder to restore the swale from the upstream (north) 6.9 elevation in a straight grade to the top of the grate inlet shown to be at elevation 6.72. 3) Define this swale across the driveway to avoid ponding of runoff along the edge of the road surface. Our review is limited to drainage issues. We have not attempted to duplicate the work of the Planning Commission or City staff with regard to setbacks, density or other zoning or subdivision regulation issues. Please contact me if you need clarification on any of the above comments. Sincerely, Downer K.

The proposed project is to be cleared of trees and stumps required for construction of a new structure. The total site is 0.13 acres with the new structure being 1,056 square feet (envelope). The soils in this area have been classified by the Chatham County Soil Survey Map as being Cuc (Chipley -Urban Land Complex). The soils on this site have not been field verified. ANALYSIS METHOD The Rational method was utilized for the analysis of the pre- development and post- development runoff for this site. Hydroflow Hydrographs software was utilized to perform these analyses and for the purpose of sizing pipes, inlets, ditches and detention. The analysis was performed utilizing the following data: DRA/NAGEAREA PRE - DEVELOPMENT RUN -OFF COEFFICIENT WEIGHTED AVERAGE = 0.35 POST - DEVELOPMENT RUN -OFF COEFFICIENT WEIGHTED AVERAGE = 0.44 IDF CURVES SAVANNAH HYDROGRAPH GENERATION METHOD = RATIONAL PRE - DEVELOPMENT SLOPE = 2 % POST DEVELOPMENT SLOPE = 2 % TIME OF CONCENTRATION PRE - DEVELOPMENT = 10 MINUTES TIME OF CONCENTRATION POST - DEVELOPMENT = 1 O MINUTES The proposed project is to be cleared of necessary trees and stumps to make way for the new structure. The resulting increased runoff, which is encountered due to new impervious area is displayed below: RUN-OFF RATE (25 YEAR .STORM) PRE - DEVELOPMENT RUN -OFF = 0.30 CFS POST - DEVELOPMENT RUN-OFF = 0.38 CFS TOTAL INCREASE IN RUN -OFF = 0.08 CFS Storm water is directed towards the new swale by existing conditions but will also be routed by gutters and downspouts. Storm water will then be directed toward the existing right -of -way by new outfall swales. SWALE INFORMATION NEW SWALES WILL CARRY 0.19 CFS EACH Hydrograph Summary Report Page 1 Hyd.
