THE CAPTUREAND EGOS DETENTION OF THE MAJORITY OFTHESE IMPROVEMENTS IS REPRESENTED BY POST -DEVELOPMENT SUBAREA A, WHERE AN UNDERGROUND DETENTION SYSTEM ATTENUATES THE RUNOFF. CHANNEL PROTECTION IS MET VIA 9VAC25-870-66 SECTION B.3.A. FLOOD PROTECTION IS MET VIA 9VAC25-870-66 SECTION C.2.B. SUBAREAS D, E, F & H REPRESENT DRAINAGE AREAS THAT SHEETFLOW OFFSITE TO EXISTING STORM SEWER INLETS ALONG BERKMAR DRIVE. THE VOLUMES FROM THESE AREAS ARE ANALYZED TO MAKE SURE AN INCREASE IN VOLUME DOES NOT IMPACT DOWNSTREAM AREAS VIA 9VAC25-870 66 SECTION D. SUBAREA HIS A NEW ONSITE DRAINAGE AREA CREATED BY THE ENTRANCE TO THIS DEVELOPMENT AND AS SUCH STORM SEWER COMPUTATIONS OF THE EXISTING PIPE RUNS EX4 TO EXI ARE PROVIDED TO SHOW THAT THE 10 YEAR STORM IS CONTAINED WITHIN THE EXISTING UNDERGROUND STORM SEWER SYSTEM. AS SHOWN IN THE CALCULATIONS PACKET, AT STRUCTURE EX1, THE CUMULATIVE VOLUME OF SHEETFLOW IN THE PROPOSED CONDITION IS LESS THAN THE CUMULATIVE VOLUME OF SHEETFLOW IN THE EXISTING CONDITION, SO THE ANALYSIS ENDS. PLEASE SEE SHEETS 12 & 13 FOR FULL DRAINAGE AREA DELINEATION TO THESE INLETS.

All dams and constructed fill to be within 95% of maximum dry density and 2%of optimum moisture content. All fill material to be approved by a geotechnical engineer. A geotechnical engineer is to be present during construction of dams. z. Pipe and riserjoints are to be watertight within stormwater Management facilities. 3. For temporary sediment traps or basins which are to be converted to permanent stormwater management facilities; conversion is not to take place until the site is stabilized, and permission has been obtained from the erosion control inspector.

BECAUSE THE TIMING OF THE INSTALLATION IS DICTATED BY THE CONTRACTOR, THE CONTRACTOR SHALL BE RESPONSIBLE FOR CONTACTING THE ENGINEER, COUNTY INSPECTOR AND CONTECH REPRESENTATIVE PRIOR TO INSTALLATION. CONTECH, OR AN EQUIVALENT PIPE MANUFACTURER, SHALL BE CONTACTED WELL AHEAD OF THE CONSTRUCTION START DATE TO ENSURE ADEQUATE LEAD TIME FOR MATERIALS AND DELIVERY. MULTIPLE SITE VISITS AND INSPECTIONS ARE REQUIRED TO BE SCHEDULED BY THE CONTRACTOR, WITH THE ENGINEER, COUNTY INSPECTOR & PIPE MANUFACTURER, DURING THE FOLLOWING STAGES OF THE UNDERGROUND DETENTION SYSTEM CONSTRUCTION PROCESS: 1. PRE -CONSTRUCTION MEETING z. INITIAL SITE PREPARATION (INCLUDING INSTALLATION OF PROJECT E&S CONTROLS) 3. EXCAVATION/GRADING (E.G., INTERIM/FINAL ELEVATIONS). 4. WHEN THE DETENTION PIPE SUBGRADE IS READY FOR PIPE CONSTRUCTION, BUT BEFORE STONE BEDDING IS INSTALLED. 5. AFTER STONE BEDDING IS PLACED AND COMPACTED, BUT PRIOR TO PIPE INSTALLATION. 6. AT THE TIME OF THE PIPE INSTALLATION. 7. AFTER PIPE INSTALLATION, BUT PRIOR TO PLACING FILL OVER THE SYSTEM. 8. FINAL INSPECTION (DEVELOPA PUNCH LIST FOR FACILITY ACCEPTANCE) PLEASE ALSO SEE BELOW, UNDER FACILITY MAINTENANCE, FOR REQUIRED INSPECTIONS AFTER INSTALLATION IS COMPLETE.
