334 <br /> Introduction <br /> The proposed project includes subdividing the current parcel into three lots as shown <br /> in the proposed SUP Site Plan included with this submittal. The proposed uses include a <br /> athletic club and baseball and softball fields each developed on dedicated parcels. These <br /> facilities will be served by their own dedicated SCM for stormwater treatment and <br /> attenuation. <br /> Stormwater Management Analysis <br /> For the purposes of this preliminary analysis, rough calculations for wet pond sizing and <br /> treatment are provided. Cover conditions in each proposed parcel were analyzed for the post <br /> development conditions and are provided in the table below. <br /> POST-DEVELOPMENT <br /> Tennis <br /> COVER CONDITION HSG SF AC CN <br /> CONCRETE, ASPHALT NA 158,713 3.64 98 <br /> ROOF NA 61,400 1.41 98 <br /> FALLOW, CROP RESIDUE B 135,767 3.12 83 <br /> OPEN SPACE, GOOD B 398,507 9.15 61 <br /> TOTAL 754,387 17.32 76 <br /> Baseball <br /> COVER CONDITION HSG SF AC CN <br /> CONCRETE, ASPHALT NA 104,626 2.40 98 <br /> ROOF NA 8,600 0.20 83 <br /> WOOD, GOOD B 135,766 3.12 55 <br /> OPEN SPACE, GOOD B 1,323,025 30.37 61 <br /> TOTAL 1,572,017 36.09 63 <br /> Main Road <br /> COVER CONDITION HSG SF AC CN <br /> IMPERVIOUS NA 83,649 1.92 98 <br /> These values were then used to determine the minimum treatment area and volume required in <br /> each SCM using the calculation guidance provided in the NCDEQ Minimum Design Criteria (MDC) <br /> Manual. Due to their large volumetric capacity, wet ponds were chosen as the primary SCM for <br /> treatment and attenuation. The wet pond sizing calculations are summarized in the tables <br /> provided in Appendix A. Some elements of the wet ponds, like average depth, were assumed as <br /> the minimum acceptable dimensions as the final dimensions are not currently known. Note that <br /> one SCM will be dedicated to both the baseball field parcel and the public road. <br />
