STRUCTURAL PRACTICES USED IN THIS SECTION CONSIST OF THE FOLLOWING. 3.01 SAFETY FENCE.• A PROTECTIVE BARRIER INSTALLED TO PREVENT ACCESS TO AN EROSION CONTROL MEASURE. TO PROHIBIT THE UNDESIRABLE USE OF AN EROSION CONTROL MEASURE BY THE PUBLIC. APPLICABLE TO ANY CONTROL MEASURE OR SERIES OF MEASURES WHICH CAN BE CONSIDERED UNSAFE BY VIRTUE OF POTENTIAL ACCESS BY THE PUBLIC. 3.02 CONSTRUCTION ENTRANCE.• A STABILIZED PAVED CONSTRUCTION ENTRANCE WITH A WASH RACK LOCATED AT POINTS OF VEHICULAR INGRESS AND EGRESS ON A CONSTRUCTION SITE. TO REDUCE THE AMOUNT OF MUD TRANSPORTED ONTO PAVED PUBLIC ROADS BY MOTOR VEHICLES OR RUNOFF. CONSTRUCTION ENTRANCES SHALL BE INSTALLED AS SHOWN ON THE PLANS TO REDUCE THE AMOUNT SEDIMENT TRANSPORTED ONTO PUBLIC ROAD WA YS. 3.05 SILT FENCE.• A TEMPORARY SEDIMENT BARRIER CONSISTING OF A SYNTHETIC FILTER FABRIC STRETCHED ACROSS AND ATTACHED TO SUPPORTING POSTS AND ENTRENCHED, TO INTERCEPT AND DETAIN SMALL AMOUNTS OF SEDIMENT FROM DISTURBED AREAS DURING CONSTRUCTION OPERATIONS IN ORDER TO PREVENT SEDIMENT FROM LEAVING THE SITE, AND TO DECREASE THE VELOCITY OF SHEET FLOWS AND LOW -TO -MODERATE LEVEL CHANNEL FLOWS. THE SILT FENCE BARRIERS SHALL BE INSTALLED DOWN SLOPE OF AREAS WITH MINIMAL GRADES TO FILTER SEDIMENT LADEN RUNOFF FROM SHEET FLOW AS INDICATED. THEY SHALL BE INSPECTED IMMEDIATELY AFTER EACH RAINFALL AND MAINTAINED IN ACCORDANCE WITH THE VIRGINIA EROSION & SEDIMENT CONTROL HANDBOOK (VESCH). 3.07 STORM DRAIN INLET PROTECTION: A SEDIMENT FILTER OR AN EXCAVATED IMPOUNDING AREA AROUND A STORM DRAIN DROP INLET OR CURB INLET. TO PREVENT SEDIMENT FROM ENTERING STORM DRAINAGE SYSTEMS PRIOR TO PERMANENT STABILIZATION OF THE DISTURBED AREA. INLET PROTECTION APPLIES WHERE STORM DRAIN INLETS ARE TO BE MADE OPERATIONAL BEFORE PERMANENT STABILIZATION OF THE CORRESPONDING DISTURBED DRAINAGE AREA. 3.08 CULVERT INLET PROTECTION: A SEDIMENT FILTER OR AN EXCAVATED IMPOUNDING AREA AROUND A STORM CULVERT. TO PREVENT SEDIMENT FROM ENTERING STORM CULVERTS PRIOR TO PERMANENT STABILIZATION OF THE DISTURBED AREA. INLET PROTECTION APPLIES WHERE STORM CULVERTS ARE EXISTING OR TO BE MADE OPERATIONAL BEFORE PERMANENT STABILIZATION OF THE CORRESPONDING DRAINAGE AREA. 3.09 TEMPORARY DIVERSION DIKE: A TEMPORARY RIDGE OF COMPACTED SOIL CONSTRUCTED AT THE TOP OR BASE OF A SLOPING DISTURBED AREA. TO DIVERT STORM RUNOFF FROM UPSLOPE DRAINAGE AREAS AWAY FROM UNPROTECTED DISTURBED AREAS AND SLOPES TO A STABILIZED OUTLET. TO DIVERT SEDIMENT -LADEN RUNOFF FROM A DISTURBED AREA TO A SEDIMENT -TRAPPING FACILITY SUCH AS A SEDIMENT TRAP OR SEDIMENT BASIN. USE WHEREVER STORMWATER RUNOFF MUST BE TEMPORARILY DIVERTED TO PROTECT DISTURBED AREAS AND SLOPES OR RETAIN SEDIMENT ON SITE DURING CONSTRUCTION. THESE STRUCTURES GENERALLY HAVE A LIFE EXPECTANCY OF 18 MONTHS OR LESS, WHICH CAN BE PROLONGED WITH PROPER MAINTENANCE. 3.12 DI VERSION: A CHANNEL CONSTRUCTED ACROSS A SLOPE WITH A SUPPORTING EARTHEN RIDGE ON THE LOWER SIDE. TO REDUCE SLOPE LENGTH AND TO INTERCEPT AND DIVERT STORMWA TER RUNOFF TO STABILIZED OUTLETS AT NON -EROSIVE VELOCITIES. APPLIES WHERE RUNOFF FROM AREAS OF HIGHER ELEVATION MAY DAMAGE PROPERTY, CAUSE EROSION, OR INTERFERE WITH THE ESTABLISHMENT OF VEGETATION ON LOWER AREAS, WHERE SURFACE AND/OR SHALLOW SUBSURFACE FLOW IS DAMAGING SLOPING UPLAND, AND WHERE THE SLOPE LENGTH NEEDS TO BE REDUCED TO MINIMIZE SOIL LOSS. 3.13 TEMPORARY SEDIMENT TRAP: A TEMPORARY PONDING AREA FORMED BY CONSTRUCTING AN EARTHEN EMBANKMENT WITH A STONE OUTLET. TO DETAIN SEDIMENT -LADEN RUNOFF FROM SMALL DISTURBED AREAS LONG ENOUGH TO ALLOW THE MAJORITY OF THE SEDIMENT TO SETTLE OUT. USE BELOW DISTURBED AREAS WHERE THE TOTAL CONTRIBUTING DRAINAGE AREA IS LESS THAN 3 ACRES, WHERE THE SEDIMENT TRAP WILL BE USED NO LONGER THAN 18 MONTHS, AND IT MAY BE CONSTRUCTED EITHER INDEPENDENTLY OR IN CONJUNCTION WITH A TEMPORARY DIVERSION DIKE. 3.14 TEMPORARY SEDIMENT BASIN: A TEMPORARY BARRIER OR DAM WITH A CONTROLLED STORMWATER RELEASE STRUCTURE FORMED BY CONSTRUCTING AN EMBANKMENT OF COMPACTED SOIL ACROSS A DRAINAGEWAY. TO DETAIL SEDIMENT -LADEN RUNOFF FROM DISTURBED AREAS IN "WET" AND `DRY" STORAGE LONG ENOUGH FOR THE MAJORITY OF THE SEDIMENT TO SETTLE OUT. APPLIES BELOW DISTURBED AREAS WHERE THE TOTAL CONTRIBUTING DRAINAGE AREA IS EQUAL TO OR GREATER THAN THREE ACRES. THERE MUST BE SUFFICIENT SPACE AND APPROPRIATE TOPOGRAPHY FOR THE CONSTRUCTION OF A TEMPORARY IMPOUNDMENT. 3.18 OUTLET PROTECTION: STRUCTURALLY LINED APRONS OR OTHER ACCEPTABLE ENERGY DISSIPATING DEVICES PLACED AT THE OUTLETS OF PIPES OR PAVED CHANNEL SECTIONS. TO PREVENT SCOUR AT STORMWATER OUTLETS, TO PROTECT THE OUTLET STRUCTURE, AND TO MINIMIZE THE POTENTIAL FOR DOWNSTREAM EROSION BY REDUCING THE VELOCITY AND ENERGY OF CONCENTRATED STORMWATER FLOWS. APPLICABLE TO THE OUTLETS OF ALL PIPES AND ENGINEERED CHANNEL SECTIONS. 3.19 RIPRAP: A PERMANENT, EROSION -RESISTANT GROUND COVER OF LARGE, LOOSE, ANGULAR STONE WITH FILTER FABRIC OR GRANULAR UNDERLINING. TO PROTECT THE SOIL FROM THE EROSIVE FORCES OF CONCENTRATED RUNOFF, SLOW THE VELOCITY OF CONCENTRATED RUNOFF WHILE ENHANCING THE POTENTIAL FOR INFILTRATION, AND TO STABILIZE SLOPES WITH SEEPAGE PROBLEMS, AND/OR NON -COHESIVE SOILS. USE WHEREVER SOIL AND WATER INTERFACE AND THE SOIL CONDITIONS, WATER TURBULENCE AND VELOCITY, EXPECTED VEGETATIVE COVER, ETC., ARE SUCH THAT THE SOIL MAY ERODE UNDER THE DESIGN FLOW CONDITIONS. 3.20 ROCK CHECK DAMS. - SMALL TEMPORARY STONE DAMS CONSTRUCTED ACROSS A SWALE OR DRAINAGE DITCH. TO REDUCE THE VELOCITY OF CONCENTRATED STORMWATER FLOWS, THEREBY REDUCING EROSION OF THE SWALE OR DITCH. THIS PRACTICE ALSO TRAPS SEDIMENT GENERATED FROM ADJACENT AREAS OR THE DITCH ITSELF, MAINLY BY PONDING OF THE STORMWATER RUNOFF.

MINIMUM CHANNEL & FLOOD PROTECTION AND VIRGINIA RUNOFF REDUCTION METHOD (VRRM) REQUIREMENTS ARE MET. PLEASE SEE THIS SHEET FOR SUMMARIES, AND THE ATTACHED STORMWATER MANAGEMENT CALCULATIONS PACKET FOR ADDITIONAL DETAILS, PERTAINING TO THIS PLAN's WATER QUALITY AND QUANTITY COMPLIANCE. WATER QUALITY SUMMARY THE STORMWATER QUALITY REQUIREMENTS FOR THIS ReDEVELOPMENT ARE MET. THE VRRM SPREADSHEET FOR ReDEVELOPMENTS WAS UTILIZED. THE SITE IS CURRENTLY BEING USED AS AN INDUSTRIAL SITE AND IS HEAVILY IMPERVIOUS WITH GRAVEL, PAVEMENT AND COMPACTED DIRT/GRAVEL ROADS & PARKING CIRCULATION AREAS. IN THE POST-ReDEVELOPMENT STATE THE OVERALL IMPERVIOUS AREA IS REDUCED. THIS REDUCTION IN IMPERVIOUS AREA MINIMIZES THE PROPOSED DEVELOPMENT's IMPACT, BUT DOES NOT COMPLETELY SATISFY THE WATER QUALITY REQUIREMENTS. AFTER THE APPLICATION OF A REDUCED IMPERVIOUS FOOTPRINT, THE PROPOSED ReDEVELOPMENT REQUIRES A PHOSPHOROUS REMOVAL RATE OF 1.24 Ibs/yr. THIS BALANCE IS MITIGATED THROUGH THE BEST MANAGEMENT PRACTICE OF PURCHASING NUTRIENT CREDITS. WATER QUANTITY SUMMARY AS STATED ABOVE, THE PROPOSED ReDEVELOPMENT REDUCES THE OVERALL IMPERVIOUS AREA. THIS REDUCTION MINIMIZES THE PROPOSED DEVELOPMENT's IMPACT FROM A STORMWATER QUANTITY STANDPOINT. THE PLAN's ANALYSIS USES THE SCS METHOD's CN LAND COVERS. AND IN ACCORDANCE WITH THE SCS TR-55 DOCUMENT, UNDER TABLE 2-2a's SECTION ENTITLED 'IMPERVIOUS AREAS', CN VALUES ARE ASSIGNED FOR THE IMPERVIOUS PAVED, GRAVEL & DIRT ROADS. THESE VALUES AND DETERMINATIONS OF IMPERVIOUS AREAS WERE USED IN THE ATTACHED SWM CALCULATIONS. IN ADDITION TO THE REDUCTION IN IMPERVIOUS AREAS, A PROPOSED DETENTION CELL WILL BE UTILIZED FOR STORMWATER QUANTITY (NOT QUALITY) COMPLIANCE. THE ATTENUATION IN THE DETENTION CELL, COUPLED WITH THE REDUCED IMPERVIOUS FOOTPRINT, ALLOWS THIS PLAN TO BE COMPLIANT WITH MINIMUM COUNTY AND VA DEQ REQUIREMENTS. 9 VAC 25-870-66 CHANNEL PROTECTION IS MET THROUGH Section B.3.a (ENERGY BALANCE COMPUTATIONS) AND THE LIMITS OF ANALYSIS IS MET VIA Section B.4. 9 VAC 25-870-66 FLOOD PROTECTION IS MET THROUGH Section C.2.b (REDUCED POST -DEVELOPMENT 10-YEAR FLOW) AND THE LIMITS OF ANALYSIS IS MET VIA Section C.3. praoasl Storm siructUres Doghouse Manhole aet�ail u_y�I�use 4 pen I rid as R-aqured 46'_ 60' a r 72" Ola_ �I NntA " • RTM ,frill datesrrrnire manholedimnater- ■ W-nnd `dimin-vLor manhvltm will iuquira d Apt by w Rh a trar,�l#Ivn to 48' QaTwter. ■ AI dflghcum manholes will to rasa VyithauIa hIAL3m.
