EROSION AND SEDIMENT CONTROL MEASURES
UNLESS OTHERWISE INDICATED, ALL VEGETATIVE AND STRUCTURAL EROSION AND
SEDIMENT CONTROL PRACTICES SHALL BE CONSTRUCTED AND MAINTAINED
ACCORDING TO MINIMUM STANDARDS AND SPECIFICATIONS OF THE VIRGINIA
EROSION AND SEDIMENT CONTROL HANDBOOK, LATEST EDITION, THE MINIMUM
STANDARDS OF THE VIRGINIA EROSION AND SEDIMENT CONTROL REGULATIONS
SHALL BE ADHERED TO UNLESS OTHERWISE WAIVED OR APPROVED BY A
VARIANCE,
STRUCTURAL PRACTICES
1. TEMPORARY CONSTRUCTII7N ENTRANCE (3.02) - A TEMPORARY CONSTRUCTION
ENTRANCE SHALL BE INSTALLED WHERE THE ACCESS ROAD INTERSECTS WITH
CLAREMONT LANE,,
2, CONSTRUCTIIIN ROAD STABILIZATION (3,03) - ACCESS ROADS, PARKING AREAS,
AND OTHER ON -SITE VEHICLE TRANSPORTATION ROUTES SHALL BE STABILIZED
WITH STONE IMMEDIATELY AFTER GRADING,
3, SILT FENCE BARRIER (3.05) - SILT FENCE BARRIERS WILL BE INSTALLED
DOWNSLIDE OF AREAS WITH MINIMAL GRADES TO FILTER RUNOFF FROM SHEET
FLOW AS INDICATED ON THE ATTACHED SITE PLAN,
4, TEMPORARY DIVERSION DIKES (3,09) - A SYSTEM OF DIVERSION DIKES TO
DIRECT FLOW INTO THE SEDIMENT BASIN WILL BE INSTALLED AS SHOWN ON
THE PLAN.
5. TEMPORARY SEDIMENT TRAPS (3.13) - A TEMPORARY SEDIMENT TRAP IS TO BE
CONSTRUCTED WHERE THE TEMPORARY STORMSEWER OUTFALL PIPE IS TO BE
LOCATED( #1), SPECIFIC DIMENSIONS OF THE EMBANKMENTS AND SPILLWAY
ARE SHOWN ON THE EROSION CONTROL DETAIL SHEET. ACTUAL LOCATIONS AND
DIMENSIONS OF THE EMBANKMENTS AND SPILLWAYS ARE SHOWN ON 'THE SITE
PLAN, CALCULATIONS FOR THE SEDIMENT TRAP ARE SHOWN WITH THE
DETAIL.
6. CHECK DAM (3.20) - SEVERAL ROCK CHECK DAMS WILL BE INSTALLED
UPSLOPE OF THE SEDIMENT BASINS TO REDUCE THE VELOCITY OF
CONCENTRATED FLOWS WHICH WILL HELP INCREASE THE EFFECTIVENESS OF
THE SEDIMENT BASINS, WHEN THE SEDIMENT REACHES THE CLEANOUT LEVEL,
IT SHALL BE REMOVED AND PROPERLY DISPOSED OF,
7, STORMWATER CONVEYANCE CHANNELS:
71 GRASS LINE CHANNELS D HAN ELS DURING THE THE INITIAL ESTABLISHMENT, GRASS
LINED CHANNELS SHOULD BE REPAIRED IMMEDIATELY AND RE- ESTABLISHED
IF NECESSARY. AFTER GRASS HAS BECOME ESTABLISHED, THE CHANNEL.
SHOULD BE CHECKED PERIODICALLY TO DETERMINE IF THE GRASS IS
WITHSTANDING FLOW VELOCITIES WITHOUT DAMAGE, IF THE CHANNEL IS
TO BE MOWED, IT SHOULD BE DONE IN A MANNER THAT IT WILL NOT
DAMAGE THE GRASS,
72, RIPRAP -LINED CHANNELS - RIPRAP LINED CHANNELS SHOULD BE CHECKED
PERIODICALLY TO ENSURE THE SCOUR IS NOT OCCURRING BENEATH FABRIC
UNDERLINING OF THE RIPRAP LAYER, THE CHANNEL SHOULD ALSO BE
CHECKED TO DETERMINE THE STONES ARE NOT DISLODGED BY LARGE
FLOWS,
7.3. IF SEDIMENT IS DEPOSITED IN A GRASS -LINED CHANNEL, IT SHOULD BE
REMOVED PROMPTLY TO PREVENT DAMAGE TO THE GRASS, SEDIMENT
DEPOSITED IN A RIPRAP CHANNEL SHOULD BE REMOVED WHEN IT REDUCES
THE CAPACITY OF THE CHANNEL
8, CHECK DAMS SHALL BE CHECKED FOR SEDIMENT ACCUMULATION AFTER EVERY
RUNOFF PRODUCING STORM EVENT, SEDIMENT SHOULD BE REMOVED WHEN IT
REACHES ONE -HALF OF THE ORIGINAL HEIGHT OF THE MEASURE, REGULAR
INSPECTIONS SHALL BE MADE TO INSURE TECH CENTER OF TECH DAM IS
LOWER THAN THE EDGES, EROSION CAUSED BY HIGH FLOWS AROUND THE
EDGES OF THE DAM SHOULD BE CORRECTED IMMEDIATELY.
9, ALL SEEDED AREAS WILL BE CHECKED REGULARLY TO ENSURE THAT A GOOD
STAND IS MAINTAINED. AREAS SHOULD BE FERTILIZED AND RESEEDED AS
NEEDED.
10. THE STORMWATER MANAGEMENT FACILITIES SHOULD BE CHECKED REGULARLY
BY THE OWNER TO ENSURE THAT IT IS STRUCTURALLY SOUND AND HAS NOT
BEEN DAMAGED BY EROSION THE EMERGENCY SPILLWAY SHALL BE CHECKED

INFILTRATION CONSTRUCTION SEQUENCE FUELING AREA - BELOW -GRADE CONTAINMENT AREA
THE FOLLOWING IS A TYPICAL CONSTRUCTION SEQUENCE TO PROPERLY INSTALL INFILTRATION PRACTICES. THE SEQUENCE MAY
NEED TO BE MODIFIED TO REFLECT THE SCALE OF INFILTRATION, SITE CONDITIONS, AND WHETHER OR NOT AN UNDERDRAIN
NEEDS TO BE INSTALLED.
INFILTRATION PRACTICES ARE PARTICULARLY VULNERABLE TO FAILURE DURING THE CONSTRUCTION PHASE FOR TWO REASONS. 10 MIL. PLASTIC L:
FIRST, IF THE CONSTRUCTION SEQUENCE IS NOT FOLLOWED CORRECTLY, CONSTRUCTION SEDIMENT CAN CLOG THE PRACTICE. IN
ADDITION, HEAVY CONSTRUCTION CAN RESULT IN COMPACTION OF THE SOIL, WHICH CAN THEN REDUCE THE SOIL'S INFILTRATION
RATE. FOR THIS REASON, A CAREFUL CONSTRUCTION SEQUENCE NEEDS TO BE FOLLOWED. IDEALLY, THE INFILTRATION PRACTICE
SHOULD BE OUTSIDE THE LIMITS OF DISTURBANCE.
DURING SITE CONSTRUCTION, THE FOLLOWING STEPS ARE ABSOLUTELY CRITICAL:
• AVOID EXCESSIVE COMPACTION BY DELINEATING THE AREA OF THE PROPOSED PRACTICE AND PREVENTING CONSTRUCTION
EQUIPMENT AND VEHICLES FROM TRAVELING OVER THE PROPOSED LOCATION.
• KEEP THE INFILTRATION PRACTICE "OFF- LINE" UNTIL CONSTRUCTION IS COMPLETE. PREVENT SEDIMENT FROM ENTERING THE
INFILTRATION SITE BY USING SUPER SILT FENCE, DIVERSION BERMS OR OTHER MEANS. IN THE EROSION AND SEDIMENT (E &S)
CONTROL PLAN, INDICATE THE EARLIEST TIME AT WHICH STORMWATER RUNOFF MAY BE DIRECTED TO A CONVENTIONAL
INFILTRATION BASIN THE E &S CONTROL PLAN MUST ALSO INDICATE THE SPECIFIC METHODS TO BE USED TO TEMPORARILY
KEEP RUNOFF FROM THE INFILTRATION SITE.
• INFILTRATION PRACTICE SITES SHOULD NEVER SERVE AS THE SITES FOR TEMPORARY SEDIMENT CONTROL DEVICES (E.G.,
SEDIMENT TRAPS, ETC.) DURING CONSTRUCTION.
• UPLAND DRAINAGE AREAS NEED TO BE COMPLETELY STABILIZED WITH A THICK LAYER OF VEGETATION PRIOR TO COMMENCING
EXCAVATION FOR AN INFILTRATION PRACTICE, AS VERIFIED BY THE LOCAL EROSION AND SEDIMENT CONTROL
INSPECTOR /PROGRAM.
INSTALLATION
THE ACTUAL INSTALLATION OF AN INFILTRATION PRACTICE IS DONE USING THE FOLLOWING STEPS:
1. EXCAVATE THE INFILTRATION PRACTICE TO THE DESIGN DIMENSIONS FROM THE SIDE, USING A BACKHOE OR EXCAVATOR. THE VARIE
FLOOR OF THE PIT SHOULD BE COMPLETELY LEVEL, BUT EQUIPMENT SHOULD BE KEPT OFF THE FLOOR AREA TO PREVENT
SOIL COMPACTION.
2. CORRECTLY INSTALL FILTER FABRIC ON THE TRENCH SIDES. LARGE TREE ROOTS SHOULD BE TRIMMED FLUSH WITH THE SIDES
OF INFILTRATION TRENCHES TO PREVENT PUNCTURING OR TEARING OF THE FILTER FABRIC DURING SUBSEQUENT INSTALLATION
PROCEDURES. WHEN LAYING OUT THE GEOTEXTILE, THE WIDTH SHOULD INCLUDE SUFFICIENT MATERIAL TO COMPENSATE FOR
PERIMETER IRREGULARITIES IN THE TRENCH AND FOR A 6 -INCH MINIMUM OVERLAP AT THE TOP OF THE TRENCH. THE FILTER
FABRIC ITSELF SHOULD BE TUCKED UNDER THE SAND LAYER ON THE BOTTOM OF THE INFILTRATION TRENCH. STONES OR
OTHER ANCHORING OBJECTS SHOULD BE PLACED ON THE FABRIC AT THE TRENCH SIDES, TO KEEP THE TRENCH OPEN 10
DURING WINDY PERIODS. VOIDS MAY OCCUR BETWEEN THE FABRIC AND THE EXCAVATED SIDES OF A TRENCH. NATURAL SOILS
SHOULD BE PLACED IN ALL VOIDS, TO ENSURE THE FABRIC CONFORMS SMOOTHLY TO THE SIDES OF EXCAVATION.
3. SCARIFY THE BOTTOM OF THE INFILTRATION PRACTICE, AND SPREAD 6 INCHES OF SAND ON THE BOTTOM AS A FILTER
LAYER.
4. ANCHOR THE OBSERVATION WELL(S), AND ADD STONE TO THE PRACTICE IN 1 -FOOT LIFTS.
5. USE SOD TO ESTABLISH A DENSE TURF COVER FOR AT LEAST 10 FEET ON EACH SIDE OF THE INFILTRATION PRACTICE TO
REDUCE EROSION AND SLOUGHING. IF THE VEGETATION IS SEEDED INSTEAD, USE NATIVE GRASSES PRIMARILY DUE TO THEIR
ADAPTABILITY TO LOCAL CLIMATES AND SOIL CONDITIONS.
INSPECTIONS
INSPECTIONS ARE NEEDED DURING AND IMMEDIATELY AFTER CONSTRUCTION TO ENSURE THAT THE INFILTRATION PRACTICE IS
BUILT IN ACCORDANCE WITH THE APPROVED DESIGN AND THIS SPECIFICATION. QUALIFIED INDIVIDUALS SHOULD USE DETAILED
INSPECTION CHECKLISTS TO INCLUDE SIGN -OFFS AT CRITICAL STAGES OF CONSTRUCTION, TO ENSURE THAT THE CONTRACTOR'S
INTERPRETATION OF THE PLAN IS CONSISTENT WITH THE DESIGNER'S INTENTIONS. AN EXAMPLE CONSTRUCTION PHASE
INSPECTION CHECKLIST FOR INFILTRATION PRACTICES IS PROVIDED AT THE END OF THIS SPECIFICATION. INSPECTION DURING THE
FOLLOWING KEY POINTS DURING CONSTRUCTION WILL HELP INSURE SUCCESSFUL PERFORMANCE:
• CHECK ELEVATIONS OF THE EXCAVATION INVERT. ENSURE THAT THE SOIL AT THE BOTTOM OF THE INFILTRATION FACILITY
HAS NOT HAS SMEARED BY THE EXCAVATION EQUIPMENT. THE BOTTOM SOIL SHOULD BE SCARIFIED WITH THE TEETH OF THE
BACKHOE BUCKET.
• INSTALLATION OF THE BOTTOM 6 -INCH SAND FILTER LAYER AND THE INITIAL LAYER OF STONE PRIOR TO PLACEMENT OF ANY
STORAGE COMPONENTS.
• TOP COVER OF PEA GRAVEL OR TURF AS REQUIRED ON PLANS.
• STABILIZATION OF ADJACENT PRE - TREATMENT FILTER STRIPS AND THE CONTRIBUTING DRAINAGE AREA PRIOR TO BRINGING
INFILTRATION AREA INTO SERVICE.
UPON FINAL INSPECTION AND ACCEPTANCE, THE GPS COORDINATES SHOULD BE LOGGED FOR ALL INFILTRATION PRACTICES AND
SUBMITTED FOR ENTRY INTO THE LOCAL BMP MAINTENANCE TRACKING DATABASE.
MAINTENANCE OF INFILTRATION FACILITIES
MAINTENANCE AGREEMENTS
THE VIRGINIA STORMWATER MANAGEMENT REGULATIONS SPECIFY THE CIRCUMSTANCES UNDER WHICH A MAINTENANCE
AGREEMENT MUST BE EXECUTED BETWEEN THE OWNER AND THE VSMP AUTHORITY AND SETS FORTH INSPECTION REQUIREMENTS,
COMPLIANCE PROCEDURES IF MAINTENANCE IS NEGLECTED, NOTIFICATION OF THE LOCAL PROGRAM UPON TRANSFER OF
OWNERSHIP, AND RIGHT -OF -ENTRY FOR LOCAL PROGRAM PERSONNEL.
• WHEN MICRO -SCALE OR SMALL -SCALE INFILTRATION PRACTICES ARE INSTALLED ON PRIVATE RESIDENTIAL LOTS, HOMEOWNERS
WILL NEED TO (1) BE EDUCATED ABOUT THEIR ROUTINE MAINTENANCE NEEDS, (2) UNDERSTAND THE LONG -TERM
MAINTENANCE PLAN, AND (3) BE SUBJECT TO A DEED RESTRICTION, DRAINAGE EASEMENT OR OTHER MECHANISM
ENFORCEABLE BY THE VSMP AUTHORITY TO ENSURE THAT INFILTRATING AREAS ARE NOT CONVERTED OR DISTURBED.
• THE MECHANISM SHOULD, IF POSSIBLE, GRANT AUTHORITY FOR LOCAL AGENCIES TO ACCESS THE PROPERTY FOR INSPECTION
OR CORRECTIVE ACTION.
MAINTENANCE INSPECTIONS
SITE INSPECTIONS H
ANNUAL ARE CRITICAL TO THE PERFORMANCE AND LONGEVITY OF INFILTRATION PRACTICES, PARTICULARLY
FOR SMALL -SCALE AND CONVENTIONAL INFILTRATION PRACTICES. MAINTENANCE OF INFILTRATION PRACTICES IS DRIVEN BY
ANNUAL INSPECTIONS THAT EVALUATE THE CONDITION AND PERFORMANCE OF THE PRACTICES, INCLUDING THE FOLLOWING:
• THE DRAWDOWN RATE SHOULD BE MEASURED AT THE OBSERVATION WELL FOR THREE DAYS FOLLOWING A STORM EVENT IN
EXCESS OF 1/2 INCH IN DEPTH. IF STANDING WATER IS STILL OBSERVED IN THE WELL AFTER THREE DAYS, THIS IS A CLEAR
SIGN THAT THAT CLOGGING IS A PROBLEM.
• CHECK INLETS, PRE - TREATMENT CELLS, AND ANY FLOW DIVERSION STRUCTURES FOR SEDIMENT BUILDUP AND STRUCTURAL
DAMAGE. NOTE IF ANY SEDIMENT NEEDS TO BE REMOVED.
• INSPECT THE CONDITION OF THE OBSERVATION WELL AND MAKE SURE IT IS STILL CAPPED.
• CHECK THAT NO VEGETATION FORMS AN OVERHEAD CANOPY THAT MAY DROP LEAF LITTER, FRUITS AND OTHER VEGETATIVE
MATERIALS THAT COULD CLOG THE INFILTRATION DEVICE.
H
• E VA LU EVALUATE THE VEGE TATI VE QUALITY TY 0 F THE ADJACENT GRASS AN D
PERFORM SPOT -
RESEEDING IF THE COVER
DENSITY IS LESS THAN 90 %.
• GENERALLY INSPECT THE UPLAND CONTRIBUTING DRAINAGE AREA FOR ANY CONTROLLABLE SOURCES OF SEDIMENT OR
EROSION.
• LOOK FOR WEEDY GROWTH ON THE STONE SURFACE THAT MIGHT INDICATE SEDIMENT DEPOSITION OR CLOGGING.
• INSPECT MAINTENANCE ACCESS TO ENSURE IT IS FREE OF WOODY VEGETATION, AND CHECK TO SEE WHETHER VALVES,
MANHOLES AND /OR LOCKS CAN BE OPENED AND OPERATED.
• INSPECT INTERNAL AND EXTERNAL INFILTRATION SIDE SLOPES FOR EVIDENCE OF SPARSE VEGETATIVE COVER, EROSION OR
SLUMPING, AND MAKE NECESSARY REPAIRS IMMEDIATELY.
BASED ON INSPECTION RESULTS, SPECIFIC MAINTENANCE TASKS WILL BE TRIGGERED. EXAMPLE MAINTENANCE INSPECTION
CHECKLISTS FOR INFILTRATION PRACTICES CAN BE ACCESSED IN APPENDIX C OF CHAPTER 9 OF THE VIRGINIA STORMWATER
MANAGEMENT HANDBOOK (2010)
ONGOING MAINTENANCE
E FF ECTIVE LONG-TERM OPERATION OF INFILTRATION PRACTICES REQUIRES A DEDICATED AND ROUTI NE MAINTENANCE INSPECTION
SCHEDULE WITH CLEAR GUIDELINES AND SCHEDULES, AS SHOWN IN TABLE 8.9 BELOW. WHERE POSSIBLE, FACILITY MAINTENANCE
SHOULD BE INTEGRATED INTO ROUTINE LANDSCAPING MAINTENANCE TASKS.
