THE 11 ' 1 OO MAJORITY OF THE PROPOSED IMPROVEMENTS WILL DRAIN TO A PROPOSED LEVEL I EXTENDED DETENTION BASIN, AS SHOWN ON THIS SHEET. THIS FACILITY WILL BE DESIGNED TO PROVIDE BOTH WATER QUALITY AND QUANTITY TREATMENT. FURTHER MEASURES WILL BE IMPLEMENTED TO PROVIDE ADDITIONAL WATER / QUALITY TREATMENT. PLEASE SEE THE ATTACHED STORMWATER MANAGEMENT - CONCEPTUAL CALCULATIONS PACKET FOR ADDITIONAL DETAILS. WATER QUALITY: / \ WATER QUALITY COMPLIANCE FOR THIS DEVELOPMENT WILL BE MET THROUGH THE USE OF BEST MANAGEMENT PRACTICES.
