F_ EA4 'X UNDER D STORMWATER MANAGEMENT NARRATIVE OVERVIEW: THE PROPOSED UNDERGROUND DETENTION SYSTEM SHALL BE INSTALLED AFTER UPLAND AREAS ARE STABILIZED AND ONLY OCCUR AFTER THE COUNTY INSPECTOR HAS PROVIDED HIS /HER APPROVAL TO BEGIN CONSTRUCTION OF THE FACILITY. THE SWM PLAN WAS ANALYZED FOR THE POST - DEVELOPMENT STATE AND TAKES INTO ACCOUNT THE ENTIRE BRIARWOOD WATERSHED, INCLUSIVE OF OTHER ONGOING DEVELOPMENTS IN ITS VICINITY. THIS SCENARIO WAS THEN COMPARED TO THE PRE - DEVELOPMENT STATE. POST- DEVELOPMENT: DETENTJON. THE UNDERGROUND DETENTION SYSTEM WAS DESIGNED FOR THE PROPOSED GAS STATION, AND INCORPORATES MINOR AMOUNTS OF RUNOFF FROM THE PROPOSED BRIARWOOD DRIVE ROAD PLAN, WHICH IS SUBMITTED UNDER A DIFFERENT SET OF PLANS. THE POST - DEVELOPMENT WATERSHED HAS A CN VALUE OF 95.3 AND IS HEAVILY IMPERVIOUS. DUE TO THE EXTENSIVE IMPERVIOUS NATURE OF THE DEVELOPMENT 75' OF 0120" CMP ARE PROPOSED TO DETAIN THE RUNOFF GENERATED FROM THIS DEVELOPMENT. ROUTING CALCULATIONS SIMULATING THIS DEVELOPMENTSs COMPLIANCE CAN BE FOUND ON THIS SHEET AND SUPPORTING SCS CALCULATIONS CAN BE FOUND WITH THE SUBMITTAL PACKAGE. WATER QUALITY. THIS PLAN PROVIDES POST - DEVELOPMENT WATER QUALITY TREATMENT VIAA FILTERRA INLET, WHICH IS STRATEGICALLY LOCATED AT THE LOW POINT OF THE PROPOSED DEVELOPMENT TO MAXIMIZE TREATMENT. THE PROPOSED WATER QUALITY FACILITY PROVIDES A REMOVAL RATE EFFICIENCY OF 74%, WHICH IS EQUAL TO THE REMOVAL RATE REQUIRED FOR THIS DEVELOPMENT. CHANNEL ADEQUACY: THIS PARCEL HAS ALREADY BEEN EVALUATED FOR DOWNSTREAM CHANNEL ADEQUACY. A CHANNEL ADEQUACY REPORT, EXHIBIT, PHOTOGRAPHS AND CALCULATIONS WERE PROVIDED WITH A SEPARATE SET OF PLANS FOR THIS AREA AND BECAUSE THIS ANALYSIS HAS A LARGER, MORE RESTRICTIVE, FLOW THAN THE POST - DEVELOPMENT FLOW PROPOSED WITH THIS PLAN THE DOWNSTREAM CHANNEL ADEQUACY REQUIREMENTS ARE STILL MET FOR THIS PARCEL WITHOUT THE NEED FOR FURTHER EVALUATION. SUMMARY: THIS WPO PLAN IS IN COMPLIANCE WITH CURRENT COUNTY & STATE REGULATIONS FOR THE STORMWATER RUNOFF ASSOCIATED WITH THE PROPOSED DEVELOPMENT. NO TES: 1. ALL FILL EMBANKMENT MATERIAL SHALL CONSIST PREDOMINANTLY OF SOIL AND BE PLACED IN SUCCESSIVE UNIFORM LAYERS NOT MORE THAN 8 INCHES IN THICKNESS BEFORE COMPACTION OVER THE ENTIRE AREA IN ACCORDANCE WITH VDOT 2007 ROAD AND BRIDGE SPECIFICATION 30304. 2. VDOT STD. IS -1 REQUIRED ON ALL STRUCTURES 3 ALL FILL SHALL BE PLACED AT 95% COMPACTION AND TESTED BY A GEOTECHNICAL ENGINEER TO ENSURE COMPACTION IS REACHED AND MAINTAINED. 4. PRIOR TO CONSTRUCTION THE CONTRACTOR SHALL TEST -DIG AT THE EXISTING INLETS & OUTFALLS TO CONFIRM THE INVERTS AND TO ENSURE THE PROPOSED GRADES CAN BE ACHIEVED. CONTRACTOR SHALL CONTACT COLLINS ENGINEERING OF ANY DISCREPANCIES IN THE HORIZONTAL OR VERTICAL ALIGNMENT PRIOR TO ORDERING AND CONSTRUCTION. 5. ALL PROPOSED SLOPES STEEPER THAN 3-1 SHALL HAVE A LOW MAINTENANCE GROUND COVER FOR STABILIZATION PURPOSES. THESE AREAS SHALL NOT BE PLANTED WITH A GRASS COVER FOR STABILIZATION & SHALL BE A GROUND COVER CHOSEN FROM TABLE 3.37C OF THE VESCH UNLESS OTHERWISE DIRECTED BY THE INSPECTOR. 6.
