IJ, Z�c9'J PILI, Stormwater Narrative G Parkstone @ Landfall 4/28/98 This project has been previously approved under the name of Woodbridge @ Landfall ( Permit # SW8 950701 ). The entire development consists of 11.70 acres. Parkstone Limited Partnership has purchased the entire tract from Landmark Development with the exception of the following lots: 1,2,3,4,5,6,7,35,36,37,38,39,&40. All of the above mentioned lots fall within Basin # 2 for the project. Basin #2 comprises 6.52 acres draining to an existing wet pond. The permitted impervious area for Pond # 2 is 137,930 sf. The revised lot plan reduces the impervious area to 134,122 sf. Based upon a reduction in Impervious area for Basin #2, the existing wet pond will not be changed. Basin #1 also drains to an existing wet pond. However the proposed impervious area for Basin #1 has been increased from 103,050 sf. to 104,282 sf. Based upon this increase, Pond #1 has been revised to accommodate the additional impervious area. Detailed calculations reflecting this change are attached. A new maintenance procedures form is attached for each pond. This development falls within the high density regulations for storm water quality. The total impervious area for the site ( 46.7 % ) is less than the original permitted amount ( 47.3% ). Stormwater runoff is generally conveyed to the ponds via underground piping and existing swales. Existing storm drainage has been relocated in few instances adjacent to the ponds. The rest of the existing infrastructure remains unchanged.
