ACCORDING TO THE ALBEMARLE COUNTY CODE SEC. 17-302, ALL PROJECTS GREATER THAN 10,000 SQUARE FEET IN DISTURBED AREA MUST COMPLY WITH THE VIRGINIA STORMWATER MANAGEMENT PROGRAM (VSMP) REGULATIONS, INCLUDING WATER QUALITY AND WATER QUANTITY REQUIREMENTS. THE PROJECT WILL RESULT IN A NET INCREASE IN THE IMPERVIOUS AREA OF APPROXIMATELY 3,718 SQUARE FEET (0.085 ACRES). EXISTING DRAINAGE PATTERNS OF THE SITE WILL BE MAINTAINED TO THE EXTENT PRACTICABLE. RUNOFF FROM THE PROJECT AREAS DRAINS TO A POINT OF ANALYSIS (POA) LOCATED AT THE OUTLET OF THE 18-INCH STORM DRAIN AT THE SOUTH OF THE PROJECT NEAR THE MID -BLOCK CROSSING. THIS IS THE LOCATION WHERE THE DRAINAGE FROM BOTH PORTIONS OF THE PROJECT WILL CONVERGE. WATER QUALITY WATER QUALITY DESIGN CALCULATIONS FOR THIS PROJECT WERE PREPARED IN ACCORDANCE WITH THE VIRGINIA RUNOFF REDUCTION METHOD (VRRM) SPREADSHEET USING THE RATIONAL METHOD. THE VRRM SPREADSHEET IS SHOWN BELOW AND CORRESPONDING DRAINAGE AREA MAP SHOWN ON SHEET C5.0. THE VRRM SPREADSHEET SHOWS THAT A POST DEVELOPMENT TOTAL PHOSPHORUS (TP) LOAD REDUCTION OF 0.26 LB./YR. IS REQUIRED FOR THIS PROJECT. AFTER EXTENSIVE INVESTIGATION, IT WAS DETERMINED THAT A BIORETENTION BASIN LOCATED ALONG THE SOUTH SIDE OF THE SCHOOL'S SECONDARY ENTRANCE WOULD BE THE MOST IDEAL LOCATION AND METHOD OF TREATMENT. THE WESTERN SECTION OF THE PARALLEL PARKING WILL BE GRADED TO CAPTURE ALL RUNOFF FROM THE PARKING LOT, THE ADJACENT SIDEWALK TO THE HIGH POINT AND ADJACENT SLOPE TO THE PROPERTY LINE AND RELEASE IT ACROSS THE NORTHERN ENTRANCE INTO THE BIORETENTION BASIN. THE SOUTHERN AND CENTRAL SIDEWALKS WILL NOT BE TREATED. IN TOTAL 0.13 ACRES OF MANAGED TURF AND 0.11 ACRES OF IMPERVIOUS SURFACE WILL BE TREATED BY THE PROPOSED LEVEL 2 BIORETENTION BASIN, WITH A 50% PHOSPHORUS REMOVAL EFFICIENCY RATE THE LEVEL 2 BIORETENTION BASIN WILL PROVIDE A PHOSPHORUS REMOVAL RATE OF 0.27 LB./YR, EXCEEDING THE REQUIRED 0.26 LB./YR. REDUCTION. THE BIORETENTION BASIN WAS DESIGNED USING VIRGINIA DEQ STORMWATER DESIGN SPECIFICATION NO. 9, DATE MARCH 1, 2011. ACCORDING TO TABLE 9.3 A LEVEL 2 BIORETENTION BASIN SHALL BE CALCULATED USING SURFACE AREA (SQ. FT.) = [(1.25)(TV)]/STORAGE DEPTH, STORAGE DEPTH IS FOUND BY CALCULATING THE SUM OF THE VOIDS OF THE BIORETENTION LAYERS. THEREFORE, THE SURFACE AREA > (1,25) (467)/1.67 OR 350 SQUARE FEET. THE DESIGNED BASIN HAS A SURFACE AREA OF 358 SQUARE FEET. WATER QUANTITY SINCE THIS PROJECT WILL BE DISCHARGING TO A MAN-MADE STORMWATER CONVEYANCE SYSTEM, IN ACCORDANCE WITH THE VIRGINIA ADMINISTRATIVE CODE 9VAC25-870-66, CHANNEL PROTECTION WILL BE SATISFIED BY CONVEYING THE POST -DEVELOPMENT PEAK FLOW RATE FROM THE 2-YEAR, 24-HOUR STORM EVENT WITHOUT CAUSING EROSION OF THE SYSTEM. THE POINT OF ANALYSIS POINT IS TO BE WHERE EITHER: 1. BASED ON LAND AREA, THE SITE'S CONTRIBUTING DRAINAGE AREA IS LESS THAN OR EQUAL TO 1.0% OF THE TOTAL WATERSHED AREA; OR 2. BASED ON PEAK FLOW RATE, THE SITE'S PEAK FLOW RATE FROM THE 1-YEAR, 24-HOUR STORM IS LESS THAN OR EQUAL TO 1.0% OF THE EXISTING PEAK FLOW RATE FROM THE 1-YEAR, 24-HOUR STORM PRIOR TO THE IMPLEMENTATION OF ANY STORMWATER QUANTITY CONTROL MEASURES. RATHER THAN PERFORM A COMPLICATED ANALYSIS OF THE. DOWNSTREAM SYSTEM, WE CHOSE TO FOLLOW SUBDIVISION 3 OF 9VAC25-870-66 BY USING THE `ENERGY BALANCE" THE "ENERGY BALANCE" USES THE MAXIMUM PEAK FLOW RATE FROM THE 1-YEAR, 24-HOUR STORM FOLLOWING THE LAND -DISTURBING ACTIVITY SHALL BE CALCULATED USING QDEVELOPED S I.F. (QPRE-DEVELOPED* RVPRE-DEVELOPED) / RVDEVELOPED, WHERE I.F. IS THE IMPROVEMENT FACTOR. SINCE THE SITE IS LESS THAN 1-ACRE THE IMPROVEMENT FACTOR IS EQUAL TO 0.9. THEREFORE, QDEVELOPED S 0.9 (3.55 * 0.573) / 0,567 OR 3.23 CFS. FROM THE ROUTING RESULTS THE 1-YEAR, 24-HOUR STORM HAS A RUNOFF RATE OF 3.20 CFS THEREBY SATISFYING THE "ENERGY BALANCE': TABLE 1: PEAK FLOW RATES GENERATED FROM SITE STORM EVENT PRE -DEVELOPED CONDITIONS (CFS) POST -DEVELOPED CONDITIONS (CFS) CHANGE 1-YR, 24-HR 3.55 3.19 -0.36 2-YR, 24-HR 9,87 9.21 -0.66 10-YR, 24-HR 19.57 18.92 -0.65 FIRST YEAR MAINTENANCE OPERATIONS SUCCESSFUL ESTABLISHMENT OF BIORETENTION AREAS REQUIRES THAT THE FOLLOWING TASKS BE UNDERTAKEN IN THE FIRST YEAR FOLLOWING INSTALLATION: • INITIAL INSPECTIONS. FOR THE FIRST 6 MONTHS FOLLOWING CONSTRUCTION, THE SITE SHOULD BE INSPECTED AT LEAST TWICE AFTER STORM EVENTS THAT EXCEED 112 INCH OF RAINFALL. • SPOT RESEEDING, INSPECTORS SHOULD LOOK FOR BARE OR ERODING AREAS IN THE CONTRIBUTING DRAINAGE AREA OR AROUND THE BIORETENTION AREA, AND MAKE SURE THEY ARE IMMEDIATELY STABILIZED WITH GRASS COVER. • FERTILIZATION. ONE-TIME, SPOT FERTILIZATION MAY BE NEEDED FOR INITIAL PLANTINGS. • WATERING. WATERING IS NEEDED ONCE A WEEK DURING THE FIRST 2 MONTHS, AND THEN AS NEEDED DURING FIRST GROWING SEASON (APRIL-OCTOBER), DEPENDING ON RAINFALL. • REMOVE AND REPLACE DEAD PLANTS. SINCE UP TO 10% OF THE PLANT STOCK MAY DIE OFF IN THE FIRST YEAR, CONSTRUCTION CONTRACTS SHOULD INCLUDE A CARE AND REPLACEMENT WARRANTY TO ENSURE THAT VEGETATION IS PROPERLY ESTABLISHED AND SURVIVES DURING THE FIRST GROWING SEASON FOLLOWING CONSTRUCTION. THE TYPICAL THRESHOLDS BELOW WHICH REPLACEMENT IS REQUIRED ARE 85% SURVIVAL OF PLANT MATERIAL AND 100% SURVIVAL OF TREES. MAINTENANCE INSPECTIONS IT IS HIGHLY RECOMMENDED THAT A SPRING MAINTENANCE INSPECTION AND CLEANUP BE CONDUCTED AT EACH BIORETENTION AREA. THE FOLLOWING IS A LIST OF SOME OF THE KEY MAINTENANCE PROBLEMS TO LOOK FOR: • CHECK TO SEE IF 75% TO 90% COVER (MULCH PLUS VEGETATIVE COVER) HAS BEEN ACHIEVED IN THE BED, AND MEASURE THE DEPTH OF THE REMAINING MULCH. • CHECK FOR SEDIMENT BUILDUP AT CURB CUTS, GRAVEL DIAPHRAGMS OR PAVEMENT EDGES THAT PREVENTS FLOW FROM GETTING INTO THE BED, AND CHECK FOR OTHER SIGNS OF BYPASSING. • CHECK FOR ANY WINTER- OR SALT -KILLED VEGETATION, AND REPLACE IT WITH HARDIER SPECIES. • NOTE PRESENCE OF ACCUMULATED SAND, SEDIMENT AND TRASH IN THE PRE-TREATMENT CELL OR FILTER BEDS, AND REMOVE IT. • INSPECT BIORETENTION SIDE SLOPES AND GRASS FILTER STRIPS FOR EVIDENCE OF ANY RILL OR GULLY EROSION, AND REPAIR IT. • CHECK THE BIORETENTION BED FOR EVIDENCE OF MULCH FLOTATION, EXCESSIVE PONDING, DEAD PLANTS OR CONCENTRATED FLOWS, AND TAKE APPROPRIATE REMEDIAL ACTION. • CHECK INFLOW POINTS FOR CLOGGING, AND REMOVE ANY SEDIMENT. • LOOK FOR ANY BARE SOIL OR SEDIMENT SOURCES IN THE CONTRIBUTING DRAINAGE AREA, AND STABILIZE THEM IMMEDIATELY, • CHECK FOR CLOGGED OR SLOW -DRAINING SOIL MEDIA, A CRUST FORMED ON THE TOP LAYER, INAPPROPRIATE SOIL MEDIA, OR OTHER CAUSES OF INSUFFICIENT FILTERING TIME, AND RESTORE PROPER FILTRATION CHARACTERISTICS. ROUTINE AND NON -ROUTINE MAINTENANCE TASKS MAINTENANCE OF BIORETENTION AREAS SHOULD BE INTEGRATED INTO ROUTINE LANDSCAPE MAINTENANCE TASKS. IF LANDSCAPING CONTRACTORS WILL BE EXPECTED TO PERFORM MAINTENANCE, THEIR CONTRACTS SHOULD CONTAIN SPECIFICS ON UNIQUE BIORETENTION LANDSCAPING NEEDS, SUCH AS MAINTAINING ELEVATION DIFFERENCES NEEDED FOR PONDING, PROPER MULCHING, SEDIMENT AND TRASH REMOVAL, AND LIMITED USE OF FERTILIZERS AND PESTICIDES. A CUSTOMIZED MAINTENANCE SCHEDULE MUST BE PREPARED FOR EACH BIORETENTION FACILITY, SINCE THE MAINTENANCE TASKS WILL DIFFER DEPENDING ON THE SCALE OF BIORETENTION, THE LANDSCAPING TEMPLATE CHOSEN, AND THE TYPE OF SURFACE COVER. A GENERALIZED SUMMARY OF COMMON MAINTENANCE TASKS AND THEIR FREQUENCY IS PROVIDED IN TABLE 9.7. OF ANALYSIS POINT IS TO BE WHERE EITHER: THE MOST COMMON NON -ROUTINE MAINTENANCE PROBLEM INVOLVES STANDING WATER. IF WATER REMAINS ON THE SURFACE FOR MORE THAN 48 HOURS AFTER A STORM, ADJUSTMENTS TO THE GRADING MAY BE NEEDED OR UNDERDRAIN REPAIRS MAY BE NEEDED. THE SURFACE OF THE FILTER BED SHOULD ALSO BE CHECKED FOR ACCUMULATED SEDIMENT OR A FINE CRUST THAT BUILDS UP AFTER THE FIRST SEVERAL STORM EVENTS. THERE ARE SEVERAL METHODS THAT CAN BE USED TO REHABILITATE THE FILTER (TRY THE EASIEST THINGS FIRST, AS LISTED BELOW): • OPEN THE UNDERDRAIN OBSERVATION WELL OR CLEANOUT AND POUR IN WATER TO VERIFY THAT THE UNDERDRAINS ARE FUNCTIONING AND NOT CLOGGED OR OTHERWISE IN NEED OF REPAIR. THE PURPOSE OF THIS CHECK IS TO SEE IF THERE IS STANDING WATER ALL THE WAY DOWN THROUGH THE SOIL. IF THERE IS STANDING WATER ON TOP, BUT NOT IN THE UNDERDRAIN, THEN THERE IS A CLOGGED SOIL LAYER. IF THE UNDERDRAIN AND STAND PIPE INDICATES STANDING WATER, THEN THE UNDERDRAIN MUST BE CLOGGED AND WILL NEED TO BE SNAKED. • REMOVE ACCUMULATED SEDIMENT AND TILL 2 TO 3 INCHES OF SAND INTO THE UPPER 8 TO 12 INCHES OF SOIL. • INSTALL SAND WICKS FROM 3 INCHES BELOW THE SURFACE TO THE UNDERDRAIN LAYER. THIS REDUCES THE AVERAGE CONCENTRATION OF FINES IN THE MEDIA BED AND PROMOTES QUICKER DRAWDOWN TIMES. SAND WICKS CAN BE INSTALLED BY EXCAVATING OR AUGERING (USING A TREE AUGER OR SIMILAR TOOL) DOWN TO THE GRAVEL STORAGE ZONE TO CREATE VERTICAL COLUMNS WHICH ARE THEN FILLED WITH A CLEAN OPEN GRADED COARSE SAND MATERIAL (ASTM C-33 CONCRETE SAND OR SIMILAR APPROVED SAND MIX FOR BIORETENTION MEDIA). A SUFFICIENT NUMBER ,OF WICK DRAINS OF SUFFICIENT DIMENSION SHOULD BE INSTALLED TO MEET THE DESIGN DEWATERING TIME FOR THE FACILITY. • REMOVE AND REPLACE SOME OR ALL OF THE SOIL MEDIA.
