ENGINEERED LEVEL SPREADER AND FOREBAY CONTRUCTION NOTES:
1. BEFORE SITE WORK BEGINS, ENGINEERED LEVEL SPREADER AND FOREBAY
BOUNDARIES SHOULD BE CLEARLY MARKED.
2. ONLY VEHICULAR TRAFFIC USED FOR ENGINEERED LEVEL SPREADER AND
FOREBAY CONSTRUCTION SHOULD BE ALLOWED WITHIN 10 FEET OF THE
BOUNDARY.
3. IF EXISTING TOPSOIL IS STRIPPED DURING GRADING, IT SHALL BE
STOCKPILED FOR LATER USE.
4. CONSTRUCTION RUNOFF SHOULD BE DIRECTED AWAY FROM THE PROPOSED
ENGINEERED LEVEL SPREADER AND FOREBAY SITE, USING PERIMETER SILT
FENCE, OR, PREFERABLY, A DIVERSION DIKE.
5. CONSTRUCTION OF THE ENGINEERED LEVEL SPREADER AND FOREBAY SHALL
NOT COMMENCE UNTIL THE CONTRIBUTING DRAINAGE AREA HAS BEEN
STABILIZED AND PERIMETER E&S CONTROLS HAVE BEEN REMOVED AND
CLEANED OUT.
6. ENGINEERED LEVEL SPREADER AND FOREBAY REQUIRE LIGHT GRADING TO
ACHIEVE DESIRED ELEVATIONS AND SLOPES. THIS SHOULD BE DONE WITH
TRACKED VEHICLES TO PREVENT COMPACTION. TOPSOIL AND OR COMPOST
AMENDMENTS SHOULD BE INCORPORATED EVENLY ACROSS THE FILTER
STRIP AREA, STABILIZED WITH SEED, AND PROTECTED BY BIODEGRADABLE
EROSION CONTROL MATTING OR BLANKETS.
7. STORMWATER SHOULD NOT BE DIVERTED INTO THE ENGINEERED LEVEL
SPREADER AND FOREBAY UNTIL THE TURF COVER IS DENSE AND WELL
ESTABLISHED.
8. ENSURE ENGINEERED LEVEL SPREADER AND FOREBAY IS COMPLETELY
LEVEL, ON THE SAME CONTOUR, AND CONSTRUCTED TO THE CORRECT
DESIGN ELEVATION.
9. PROVIDE AS -BUILT SURVEYS.
10. DESIGNATED INSPECTOR SHALL EVALUATE THE PERFORMANCE OF THE
ENGINEERED LEVEL SPREADER AND FOREBAY AFTER THE FIRST BIG STORM
EVENT TO LOOK FOR EVIDENCE OF GULLIES, OUTFLANKING, UNDERCUTTING,
OR SPARSE VEGETATION COVER. SPOT REPAIRS SHALL BE MADE.
MAINTENANCE INSPECTIONS:
1. 1. FLOWS THROUGH THE ENGINEERED LEVEL SPREADER AND FOREBAY DO
NOT SHORT-CIRCUIT THE OVERFLOW CONTROL SECTION;
2. 2. DEBRIS AND SEDIMENT DOES NOT BUILD UP IN THE FOREBAY;
3. 3. FOOT OR VEHICULAR TRAFFIC DOES NOT COMPROMISE THE ENGINEERED
LEVEL SPREADER AND FOREBAY;
4. 4. SCOUR AND EROSION DO NOT OCCUR WITHIN THE ENGINEERED LEVEL
SPREADER AND FOREBAY;
5. 5. SEDIMENTS ARE CLEANED OUT OF THE FOREBAY; AND
6. 6. VEGETATIVE DENSITY EXCEEDS A 90% COVER IN THE BOUNDARY ZONE.
CONSTRUCTION RECORD DRAWINGS FOR VSMP
A. A SIGNED AND DATED PROFESSIONAL SEAL OF THE PREPARING ENGINEER OR
SURVEYOR.
B. THE NAME AND ADDRESS OF THE FIRM AND INDIVIDUAL PREPARING THE
DRAWINGS ON THE TITLE SHEET.
C. THE CONSTRUCTED LOCATION OF ALL ITEMS ASSOCIATED WITH EACH
FACILITY, AND THE INSPECTION RECORDS TO VERIFY PROPER DIMENSIONS,
MATERIALS AND INSTALLATION. THE ITEMS INCLUDE, BUT ARE NOT LIMITED TO THE
FOLLOWING:
1. INSPECTION RECORDS AND PHOTOGRAPHS FOR PIPE TRENCHES AND
BEDDING, INCLUDING UNDERDRAINS.
2. VIDEO PIPE INSPECTION FOR ANY PIPES WHICH ARE NOT ACCESSIBLE OR
VIEWABLE.
3. UPDATED LOCATION WITH GEO-COORDINATES OF ALL FACILITIES.
4. VERIFIED DRAINAGE AREA MAPS FOR THE DRAINAGE AREA TREATED, AND
FOR DRAINAGE TO THE FACILITIES.
5. CURRENT PHYSICAL AND TOPOGRAPHIC SURVEY FOR ALL EARTHEN
STRUCTURES. PONDS SHOULD INCLUDE A SURVEY OF THE POND BOTTOM.
SURVEYS SHOULD VERIFY POND VOLUMES ARE PER DESIGN. CORRECTIONS
MAY BE REQUIRED FOR ALTERATIONS FROM THE DESIGN.
6. PLANTS, LOCATION AND TYPE.
7. PLANS AND PROFILES FOR ALL CULVERTS, PIPES, RISERS, WEIRS AND
DRAINAGE STRUCTURES - DISPLAY THE INSTALLED TYPE OF DRAINAGE
STRUCTURES, CULVERT/PIPE SIZE, WEIRS, MATERIALS, INLETS OR END
TREATMENT(S), INLET AND OUTLET PROTECTION, ALIGNMENT AND INVERT
ELEVATIONS COMPARED TO DESIGN.
8. COMPUTATIONS: FOR SIGNIFICANT DEVIATIONS FROM DESIGN, PROVIDE
SEALED COMPUTATIONS VERIFYING THAT THE AS -BUILT CONDITION IS
EQUIVALENT OR BETTER THAN DESIGN.
9. DITCH LINES - DISPLAY THE CONSTRUCTED LOCATION OF ALL DITCH LINES
AND CHANNELS, INCLUDING TYPICAL SECTIONS AND LININGS.
10. EASEMENTS - SHOW ALL PLATTED EASEMENTS WITH DEAD BOOK
REFERENCES LABELED. FACILITIES AND DRAINAGE MUST BE WITHIN PLATTED
EASEMENTS. PROVIDE COPIES OF RECORDED DOCUMENTS.
11. GUARDRAIL, FENCES OR OTHER SAFETY PROVISIONS - DISPLAY THE
CONSTRUCTED LOCATION OF ALL SAFETY PROVISIONS; FENCES, GUARDRAIL,
INCLUDING THE TYPE, LENGTH AND APPLIED END TREATMENTS, COMPARED

Ideally, these BMP areas should be inspected annualty, with the inspection conducted during the non -
growing season when it is easier to observe the flow path. Once established, vegetated fitter strips have
minimal maintenance needs outside of the Spring clean up: regular mowing, repair of check dams and
other measures to maintain the hydraulic efficiency of the fitter strip and a dense, healthy grass cover.
Grass fitter strips and boundary zones must be mowed at least twice a year to prevent woody growth. A
conservation easement may be required to ensure that the vegetated filter strip area and any newly
established orrestored forest covermay not be cleared. Also, a responsible party should ensure that routine
forest improvements are made over time (i.e., thinning, invasive plant removal, etc.).

NOTES:
1. WIRE FENCE REINFORCEMENT FOR SILT FENCE SHALL BE A MINIMUM OF 14 GAUGE AND SHALL HAVE A MAXIMUM MESH SPACING OF 6 INCHES.
2. THE WIRE SHALL EXTEND A MINIMUM 4 INCHES INTO THE GROUND AND MUST BE FASTENED SECURELY TO THE UPSLOPE SIDE OF THE POSTS USING HEAVY-DUTY WIRE STAPLES AT
LEAST ONE INCH LONG, TYE WIRES OR HOG RINGS.
3. STEEL POSTS (STANDARD "U" OR "T" SECTION) MUST HAVE A MINIMUM WEIGHT OF 1.33 POUNDS PER LINEAR FOOT AND SHALL HAVE A MINIMUM LENGTH OF 5 FEET.
4. SUPPORT POSTS OR STAKES FOR THIS TYPE OF APPLICATION SHALL BE PLACED A MAXIMUM 10-FEET APART (SEE PLATE 3.01-1) EXCEPT WITHIN THE WET STORAGE AREA, THE WET
STORAGE AREA SHALL HAVE THE POSTS OR STAKES PLACED A MAXIMUM 3-FEET APART FOR ADDED SUPPORT.
5. SILT FENCE SHALL CONFORM TO THE CONSTRUCTION SPECIFICATIONS FOR "EXTRA STRENGTH" FOUND IN TABLE 3.05-13 AND SHALL BE CUT FROM A CONTINUOUS ROLL TO AVOID
JOINTS.
6. THE FABRIC SHALL BE ENTRENCHED A MINIMUM 8" IN DEPTH AND BACK FILLED WITH CLEAN SOIL; THE SOIL SHALL BE COMPACTED TO 95% OVER THE FILTER FABRIC.
7. THE HEIGHT OF THE SILT FENCE SHALL BE A MINIMUM OF 34 INCHES ABOVE THE ORIGINAL GROUND AND SHALL NOT EXCEED 48 INCHES ABOVE GROUND ELEVATION.
8. THE OUTLET FOR THE MODIFIED MUD TRAP SHALL CONSIST OF A STONE SECTION OF THE WIRE -SUPPORTED SILT FENCE LOCATED AT THE LOW POINT OR POINT OF
CONCENTRATION FOR STORM FLOWS. FOR DRAINAGE AREAS LESS THAN ONE ACRES, THE MEASURE SHALL CONSIST OF WIRE -SUPPORTED SILT FENCE INSTALLED AS A CONTINUOUS
STRUCTURE WITH CLASS Al STONE CAREFULLY PLACED ON EITHER SIDE OF THE FENCE FOR OUTLET STABILITY, NO FILTER STONE REQUIRED. FOR DRAINAGE AREAS FROM 1 TO 3
ACRES, THE MEASURE SHALL CONSIST OF THE WIRE -SUPPORTED SILT FENCE INSTALLED WITH AN OPENING FROM 4 TO 8 FEET WIDE LOCATED IN THE LOW POINT OR POINT OF
CONCENTRATION FOR STORM FLOWS. THE OPENING SHALL HAVE A COMBINATION COURSE AGGREGATE AND RIPRAP INSTALLED TO PROVIDE FOR FILTERING/DETENTION AS WELL
AS OUTLET STABILITY. THE SMALLER STONE SHALL BE VDOT #3, #357 OR #5 COURSE AGGREGATE (SMALLER STONE SIZES WILL ENHANCE FILTER EFFICIENCY) AND RIPRAP SHALL
BE "CLASS 1." FILTER CLOTH THAT MEETS THE PHYSICAL REQUIREMENTS NOTED IN STD. & SPEC 3.19, RIPRAP SHALL BE PLACED AT THE STONE -SOIL INTERFACE TO ACT AS
A "SEPARATOR." THE CREST OF THE STONE OUTLET MUST BE AT LEAST 1.0 FOOT BELOW THE TOP OF THE WIRE -SUPPORTED SILT FENCE TO ENSURE THAT THE FLOW WILL TRAVEL OVER
THE STONE AND NOT OVER THE FENCE. THE OUTLET SHALL BE CONFIGURED AS NOTED IN PLATE 3.12-2.
9. MAINTENANCE:SILT FENCE SHALL BE INSPECTED IMMEDIATELY AFTER EACH RAINFALL AND AT LEAST DAILY DURING PROLONGED RAINFALL. ANY REQUIRED REPAIRS SHALL BE
MADE IMMEDIATELY.
A. CLOSE ATTENTION SHALL BE PAID TO THE REPAIR OF DAMAGED SILT FENCE RESULTING FROM END RUNS AND UNDERCUTTING.
B. SHOULD THE FABRIC ON SILT FENCE DECOMPOSE OR BECOME INEFFECTIVE PRIOR TO THE END OF THE EXPECTED USABLE LIFE AND THE BARRIER IS STILL NECESSARY, THE FABRIC
SHALL BE REPLACED PROMPTLY.
C.SEDIMENT SHALL BE REMOVED AND THE TRAP RESTORED TO ITS ORIGINAL DIMENSIONS WHEN THE SEDIMENT HAS ACCUMULATED TO ONE HALF OF THE DESIGN VOLUME OF THE
WET STORAGE OR EMINENT FAILURE IS EVIDENT. SEDIMENT REMOVAL FROM THE AREA SHALL BE DEPOSITED IN A SUITABLE AREA AND IN SUCH A MANNER THAT IT WILL NOT ERODE
AND CAUSE SEDIMENTATION PROBLEMS.
D. STONE SHALL BE REGULARLY CHECKED TO ENSURE THAT FILTRATION PERFORMANCE IS MAINTAINED. STONE CHOKED WITH SEDIMENT SHALL BE REMOVED AND CLEANED OR
REPLACED.
E. THE STRUCTURE SHALL BE CHECKED REGULARLY TO ENSURE THAT ITS CENTER IS AT LEAST 1 FOOT BELOW THE TOP OF THE FENCE.
F. TEMPORARY STRUCTURES SHALL BE REMOVED WHEN THEY HAVE SERVED THEIR USEFUL PURPOSE, BUT NOT BEFORE UPSLOPE AREA HAS BEEN PERMANENTLY STABILIZED.
