292 <br /> Introduction <br /> The proposed project includes subdividing the current parcel into three "pods" as <br /> shown in the proposed Master Plan DevelopmentāConditional Zoning Site Plan included <br /> with this submittal. The proposed uses include two schools, a tennis club and baseball and <br /> softball fields each developed on dedicated parcels. These facilities will be served by their <br /> own dedicated SCM for stormwater treatment and 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 /> Schools <br /> COVER CONDITION HSG SF AC CN <br /> CONCRETE, ASPHALT NA 264,200 6.07 98 <br /> ROOF NA 70,400 1.62 98 <br /> FALLOW, CROP RESIDUE B 0.00 83 <br /> OPEN SPACE, GOOD B 810,554 18.61 61 <br /> TOTAL 1,145,154 26.29 72 <br /> Tennis <br /> COVER CONDITION HSG SF AC CN <br /> CONCRETE, ASPHALT NA 222,464 5.11 98 <br /> ROOF NA 48,678 1.12 98 <br /> FALLOW, CROP RESIDUE B 0.00 83 <br /> OPEN SPACE, GOOD B 535,667 12.30 61 <br /> TOTAL 806,808 18.52 73 <br /> Baseball <br /> COVER CONDITION HSG SF AC CN <br /> IMPERVIOUS NA 113,226 2.60 98 <br /> FALLOW, CROP RESIDUE NA 0 0.00 83 <br /> WOOD, GOOD B 0.00 55 <br /> OPEN SPACE, GOOD B 1,544,546 35.46 61 <br /> TOTAL 1,657,772 38.06 64 <br /> Main Road <br /> COVER CONDITION HSG SF AC CN <br /> IMPERVIOUS NA E883,649 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.
