THE SITE HAS BEEN ANALYZED AND BREAKS DOWN THE DEVELOPMENT INTO TWO MAJOR SECTIONS, THE CONSTRUCTION OF THE PARKING LOT AND THE CONSTRUCTION OF THE BUILDING & FUTURE HARD COURT. THE PROPOSED PARKING LOT SHALL BE CONSTRUCTED WITH A PERMEABLE PAVER SYSTEM, WHICH HANDLES BOTH THE WATER QUALITY AND WATER QUANTITY TREATMENT FOR THIS IMPERVIOUS AREA. AFTER TREATMENT, THIS DRAINAGE OUTFALLS INTO THE EXISTING ROADSIDE DITCH ASSOCIATED WITH THE SOUTHERN PARKWAY, WHERE IT CURRENTLY DRAINS. SEE FINAL SITE PLANS FOR PARKING LOT PERMEABLE PAVER DESIGN. THE PROPOSED BUILDING SHALL BE PARTIALLY LOCATED OVERTOP OF AN EXISTING PAVED BASKETBALL COURT. IN ACCORDANCE WITH DIRECTION FROM COUNTY ENGINEERING, THE PROPOSED BIORETENTION BASIN FLOOR AREA SHALL BE SIZED TO BE 5% OF THE PROPOSED BUILDING & FUTURE HARD COURT's IMPERVIOUS AREAS, LESS THE EXISTING IMPERVIOUS AREAS FROM THE BASKETBALL COURT BEING REMOVED. THIS BIORETENTION BASIN WILL PROVIDE WATER QUALITY FOR THIS PORTION OF THE PROPOSED DEVELOPMENT, AND A CONTRIBUTION SHALL BE MADE TO THE PRO -RATA SHARE PROGRAM TO HANDLE THE WATER QUANTITY ASPECT OF THIS IMPERVIOUS AREA. THE PROPOSED BIORETENTION BASIN SHALL DRAIN TO THE ADJACENT FLOODPLAIN AREA & STREAM, CONSISTENT WITH THE CURRENT LOCATION OF RUNOFF FROM THE BASKETBALL COURT BEING REMOVED. ALL PROPOSED IMPERVIOUS AREAS ARE TREATED THROUGH ONSITE FACILITIES, OR THROUGH THE PRO -RATA SHARE PROGRAM.
