ER&OSION SEDIMENT CONTROL
MEASURES:
STRUCTURAL EROSION AND SEDIMENT CONTROL PRACTICES SHALL BE IN ACCORDANCE
KITH THE 14RGINIA EROSION AND SEDIMENT CONTROL HANDBOOK. STRUCTURAL
PRACTICES USED IN THIS SECTION CONSIST OF THE FOLLOWING.
3.01 SAFETY FENCE:
A PR07FC77VE 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 P07ENTIAL 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 ROADWAYS.
3.05 SILT FENCE:
A TEMPORARY SEDIMENT BARRIER CONSIS77NG 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 WRGINIA 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 STABILIZAT70N OF THE DISTURBED AREA. INLET PR07EC77ON APPLIES
WHERE STORM DRAIN INLETS ARE TO BE MADE OPERATIONAL BEFORE PERMANENT
STABILIZATION OF THE CORRESPONDING DISTURBED 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-7RAPPING FACILITY SUCH
AS A SEDIMENT TRAP OR SEDIMENT BASIN. USE WHEREVER STORMW47ER 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.
3.11 TEMPORARY RIGHT-OF-WAY DIVERSION:
A RIDGE OF COMPACTED SOIL OR LOOSE ROCK OR GRAVEL CONSTRUCTED ACROSS DISTURBED
RIGHTS -OF -WAY AND SIMILAR SLOPING AREAS. TO SHORTEN THE FLOW LENGTH WITHIN A
SLOPING RIGHT-OF-WAY THEREBY REDUCING THE EROSION P07ENTIAL BY DIVER77NG STORM
RUNOFF TO A STABILIZED OUTLET. GENERALLY, EARTHEN DIVERSIONS ARE APPLICABLE WHERE
THERE WILL BE LITTLE OR NO CONSTRUCTION TRAFFIC WITHIN THE RIGHT-OF-WAY. GRAVEL
STRUCTURES ARE MORE APPLICABLE TO ROADS AND OTHER RIGHTS -OF -WAY WHICH
ACCOMMODATE VEHICULAR TRAFFIC.
J.14 TEMPORARY SEDIMENT BASIN:
A TEMPORARY BARRIER OR DAM WITH A CONTROLLED STORMW47ER RELEASE STRUCTURE
FORMED BY CONSTRUCTING AN EMBANKMENT OF COMPACTED SOIL ACROSS A DRAINAGEWAY. TO
DETAIN 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 774AN THREE ACRES. THERE MUST BE SUFFICIENT SPACE AND APPROPRIATE
TOPOGRAPHY FOR THE CONSTRUCTION OF A TEMPORARY IMPOUNDMENT.
STRUCTURALLY LINED APRONS OR OTHER ACCEPTABLE ENERGY DISSIPATING DEVICES PLACED
AT THE OUTLETS OF PIPES OR PAVED CHANNEL SECTIONS. TO PREVENT SCOUR AT
S7ORMW47ER OUTLETS, TO PR07ECT THE OUTLET STRUCTURE, AND TO MINIMIZE THE P07EN77AL
FOR DOWNSTREAM EROSION BY REDUCING THE VELOCITY AND ENERGY OF CONCENTRATED
STORMW47ER FLOWS APPLICABLE TO THE OUTLETS OF ALL PIPES AND ENGINEERED CHANNEL
SECTIONS
J. 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 P07EN77AL 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.
3.31 TEMPORARY SEEDING:
THE ESTABLISHMENT OF A TEMPORARY VEGETATIVE COVER ON DISTURBED AREAS BY SEEDING
WITH APPROPRIATE RAPIDLY GROWING ANNUAL PLANTS. TO REDUCE EROSION AND
SEDIMENTATION BY STABILIZING DISTURBED AREAS THAT WILL NOT BE BROUGHT TO FINAL
GRADE FOR A PERIOD OF MORE THAN 30 DAYS. TO REDUCE DAMAGE FROM SEDIMENT AND
RUNOFF TO DOWNSTREAM OR OFF -SITE AREAS, AND TO PROVIDE PR07EC77ON TO BARE SOILS
EXPOSED DURING CONSTRUCTION UNTIL PERMANENT VEGETATION OR 07HER EROSION CONTROL
MEASURES CAN BE ESTABLISHED.
332 PERMANENT STABILIZATION:
THE ESTABLISHMENT OF PERENNIAL VEGETATIVE COVER ON DISTURBED AREAS BY PLAN77NG
SEED. TO REDUCE EROSION AND DECREASE SEDIMENT YIELD FROM DISTURBED AREAS. TO
PERMANENTLY STABILIZE DISTURBED AREAS IN A MANNER THAT IS ECONOMICAL, ADAPTABLE TO
S17E CONDITIONS, AND ALLOWS SELECTION OF THE MOST APPROPRIA7E PLANT MATERIALS TO
IMPROVE WILDLIFE HABITAT. TO ENHANCE NATURAL BEAUTY. UPON COMPLETION OF
CONSTRUCTION ACTIVITIES, ALL AREAS WILL RECEIVE A PERMANENT VEGETATIVE COVER.
338 TREE PRESERVATION AND PROTECTION:
PROTECTION OF DESIRABLE TREES FROM MECHANICAL OR OTHER INJURY DURING LAND
DISTURBING AND CONSTRUCTION AC770TY. TO ENSURE THE SURVIVAL OF DESIRABLE TREES
WHERE THEY WILL BE EFFEC77VE FOR EROSION AND SEDIMENT CONTROL, WATERSHED
PROTECTION, LANDSCAPE BEAUTIFICATION, DUST AND POLLUTION CONTROL, NOISE REDUCTION,
SHADE AND 07HER ENVIRONMENTAL BENEFITS WHILE THE LAND IS BEING CONVERTED FROM
FOREST TO URBAN -TYPE USES. APPLIES IN TREE -INHABITED AREAS SUBJECT TO LAND
DISTURBING ACTIVITIES.
3.39 DUST CONTROL:
REDUCING SURFACE AND AIR MOVEMENT OF DUST DURING LAND DISTURBING DEMOLITION AND
CONSTRUCTION ACTIVITIES. TO PREVENT SURFACE AND AIR MOVEMENT OF DUST FROM
EXPOSED SOIL SURFACES AND REDUCE THE PRESENCE OF AIRBORNE SUBSTANCES WHICH MAY
PRESENT TR LT74 HAZARDS, TRAFFIC SAFETY PROBLEMS OR HARM ANIMAL OR PLANT LIFE. SOIL DESCRIPTION
