MULCHING APPLICATION RATES ARE SHOWN ON THE PLAN PERMANENT STABILIZATION: ONCE THE SITE HAS BEEN BROUGHT TO FINAL GRADE AND GRAVEL HAS BEEN PLACED, TOPSOIL SHALL BE SPREAD ON ALL DISTURBED AREAS EVENLY. FERTILIZER, SEED, AND A COVERING SHALL THEN BE INSTALLED IN ACCORDANCE WITH PERMANENT SEEDING (VESCH# 3.32) FOLLOWING APPLICATION RATES SHOWN ON THE PLAN. STORMWATER MANAGEMENT NARRATIVE PROJECT DESCRIPTION: THIS PROJECT PROPOSES THE ADDITION OF 48 EMPLOYEE PARKING SPACES, A TRAILER STORAGE YARD, AND AN EXPANDED LOADING DOCK. A BIORETENTION BASIN AND FILTER ARE PROPOSED FOR WATER QUALITY TREATMENT OF THE NEW IMPERVIOUS AREA. MODIFICATIONS TO THE EXISTING OUTFALL STRUCTURE AND BOTTOM OF THE REGIONAL STORMWATER MANAGEMENT FACILITY ARE PROPOSED FOR WATER QUANTITY PURPOSES. EXISTING CONDITIONS: THE WORK PROPOSED BY THIS PLAN INCLUDES 1.05 ACRES OF ADDITIONAL IMPERVIOUS AREA AND IS GOVERNED BY THE PART IIB STORMWATER DESIGN CRITERIA. A BIORETENTION BASIN AND FILTER ARE PROPOSED FOR WATER QUALITY TREATMENT OF THE NEW IMPERVIOUS AREA. PER THE ATTACHED VRRM WORKSHEETS, THE PROPOSED BIORETENTION BASIN AND FILTER EXCEED THE TARGET PHOSPHORUS LOAD REDUCTION BY 0.1 LB/YEAR FOR THE DISTURBED SITE. THE EXISTING STORMWATER MANAGEMENT FACILITY IS TO BE MODIFIED TO MEET THE ENERGY BALANCE-WATER QUANTITY REQUIREMENTS AS SHOWN ON THE PLANS. PER THE ATTACHED HYDROGRAPHS AND HAND CALCULATIONS, THE BIORETENTION BMP'S AND MODIFIED STORMWATER MANAGEMENT FACILITY REDUCE RUNOFF TO LEVELS THAT SATISFY THE ENERGY BALANCE EQUATION. THE EXISTING STORMWATER MANAGEMENT FACILITY IS OVERGROWN WITH WOODY VEGETATION. THE PLAN CALLS FOR THE ENTIRE STORMWATER MANAGEMENT FACILITY TO BE CLEARED AND GRUBBED. ANIMAL BURROWS SHOULD BE FILLED WITH COMPACTED GOOD CLEAN MATERIAL. UNDER NO CIRCUMSTANCES SHOULD STUMPS BE ALLOWED TO REMAIN IN THE FACILITY. ONCE THE AREA HAS BEEN CLEARED AND GRUBBED, PERMANENT SEEDING AND MULCHING SHOULD BE APPLIED. SOILS: THE ENTIRE PROPOSED PROJECT AREA HAS PREVIOUSLY BEEN DISTURBED BY GRADING ACTIVITIES; HOWEVER, ACCORDING TO THE NRCS WEB SOIL SURVEY, THERE ARE 4 SOILS ONSITE IN THE DISTURBED AREA. THE FIRST IS CULLEN LOAM , ABBREVIATED CUB, WITH 2 TO 6 PERCENT SLOPES. THE SECOND IS CULLEN LOAM, ABBREVIATED CUC2, WITH 6 TO 15 PERCENT SLOPES. THE THIRD IS CECIL FINE SANDY LOAM, ABBREVIATED CCB2, WITH 2 TO 6 PERCENT SLOPES. THE FINAL SOIL IS CECIL FINE SANDY LOAM, ABBREVIATED CCC2, WITH 6 TO 15 PERCENT SLOPES. STORMWATER MANAGEMENT: THE STORMWATER MANAGEMENT DESIGN IS BASED UPON IIB CITERIA. THE SITE IS CONSIDERED A REDEVELOPMENT SITE. THREE STORMTECH FILTERS ARE UTILIZED TO TREAT THE MAJORITY OF THE PARKING LOTS AND PAVED AREAS FOR WATER QUALITY. ALL OF THESE FLOW INTO THE EXISTING POND, WHICH IS CONVERTED TO A BIORETENTION 1. THE ULTIMATE DISCHARGE FROM THE SITE IS ANALYZED WITH THE ENERGY BALANCE EQUATION. BOTH THE WATER QUALITY REQUIREMENTS AND WATER QUANTITY REQUIREMENTS ARE MET. MAINTENANCE: THE STORMWATER MANAGEMENT FACILITY SHALL HAVE A THICK, HEALTHY STAND OF GRASS COVER, FREE OF TREES AND BRUSH. THE FACILITY SHOULD BE MOWED PERIODICALLY DURING THE GROWING SEASON. THE GRASS SHOULD NOT BE CUT LESS THAN 6” TALL. LIME AND FERTILIZE THE FACILITY AS TALL. LIME AND FERTILIZE THE FACILITY AS NECESSARY TO MAINTAIN A THICK, HEALTHY STAND OF GRASS COVER FOLLOWING RECOMMENDATIONS FROM SOIL TESTING. REPAIR ALL EROSION ISSUES IN A TIMELY FASHION ONCE DISCOVERED. BARE AREAS SHALL BE SEEDED AND MULCHED IN A TIMELY FASHION. ALL ANIMAL BURROWS SHALL BE BACKFILLED AND COMPACTED ONCE THE ANIMAL HAS BEEN REMOVED FROM THE FACILITY. REMOVE ALL TREES, WOODY VEGETATION, AND OTHER DEEP-ROOTED GROWTH IN A TIMELY FASHION ONCE DISCOVERED. ANY MAINTENANCE ISSUES RELATING TO THE PRINCIPAL SPILLWAY SHOULD BE REVIEWED AND APPROVED BY A PROFESSIONAL ENGINEER.
