CRITICAL AREAS

ESC MEASURES SHALL BE PROVIDED ADJACENT TO WETLANDS AND STREAMS.

EROSION AND SEDIMENT CONTROL MEASURES

UNLESS OTHERWISE INDICATED, ALL VEGETATIVE AND STRUCTURAL EROSION AND SEDIMENT CONTROL PRACTICES SHALL BE CONSTRUCTED AND MAINTAINED ACCORDING TO THE MINIMUM STANDARDS AND SPECIFICATIONS OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK.

STRUCTURAL PRACTICES

TEMPORARY STONE CONSTRUCTION ENTRANCE (1992 VESCH STD & SPEC 3.02)

A STABILIZED STONE PAD WITH A FILTER FABRIC UNDERLINER 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 ROAD STABILIZATION (1992 VESCH STD. & SPEC. 3.03):

THE TEMPORARY STABILIZATION OF ACCESS ROADS, SUBDIVISION ROADS, PARKING AREAS, AND OTHER ON-SITE VEHICLE TRANSPORTATION ROUTES WITH STONE IMMEDIATELY AFTER GRADING. THE PURPOSE IS TO REDUCE THE EROSION OF TEMPORARY ROADBEDS BY CONSTRUCTION TRAFFIC DURING WET WEATHER AND TO REDUCE THE EROSION AND SUBSEQUENT REGARDING OF PERMANENT ROADBEDS BETWEEN THE TIME OF

INITIAL GRADING AND FINAL STABILIZATION.

SILT FENCE (1992 VESCH STD. & SPEC. 3.05):

A TEMPORARY SEDIMENT BARRIER CONSISTING OF A FILTER FABRIC STRETCHED ACROSS AND ATTACHED TO SUPPORTING POSTS AND ENTRENCHED. SILT FENCE IS INSTALLED TO INTERCEPT AND DETAIN SMALL AMOUNTS OF SEDIMENT FROM DISTURBED AREAS DURING CONSTRUCTION IN ORDER TO PREVENT SEDIMENT FROM LEAVING THE SITE AND TO DECREASE THE VELOCITY OF SHEET FLOWS AND

LOW-TO-MODERATE CHANNEL FLOWS.

STORM DRAIN INLET PROTECTION (1992 VESCH STD & SPEC. 3.07)

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 STABILIZATION OF THE DISTURBED AREA. DIFFERENT TYPES OF STRUCTURES ARE

APPLICABLE TO DIFFERENT CONDITIONS.

CULVERT INLET PROTECTION (1992 VESCH STD. & SPEC. 3.08):

A SEDIMENT FILTER LOCATED AT THE INLET TO STORM SEWER CULVERTS TO PREVENT SEDIMENT FROM ENTERING, ACCUMULATING IN AND BEING TRANSFERRED BY A CULVERT AND ASSOCIATED DRAINAGE SYSTEM PRIOR TO PERMANENT STABILIZATION OF A DISTURBED PROJECT AREA AND TO PROVIDE EROSION CONTROL AT CULVERT INLETS DURING THE PHASE OF A PROJECT WHERE ELEVATION AND DRAINAGE PATTERNS CHANGE, CAUSING ORIGINAL CONTROL MEASURES TO BE INEFFECTIVE OR IN NEED OF REMOVAL.

TEMPORARY SEDIMENT TRAP (1992 VESCH STD. & SPEC 3.13);

A TEMPORARY PONDING AREA FORMED BY CONSTRUCTING AN EARTHEN EMBANKMENT WITH A STONE OUTLET. PURPOSE IS TO DETAIN SEDIMENT-LADEN RUNOFF- FROM SMALL DISTURBED AREAS LONG ENOUGH TO ALLOW THE MAJORITY OF THE SEDIMENT TO SETTLE OUT. TOTAL CONTRIBUTING DRAINAGE AREA SHALL BE LESS THAN 3 ACRES. TRAP(S) SHALL BE CONSTRUCTED AS A FIRST STEP IN ANY AND-DISTURBING ACTIVITY AND SHALL BE MADE FUNCTIONAL BEFORE UPSLOPE LAND DISTURBANCE TAKES PLACE.

TEMPORARY SEDIMENT BASIN (1992 VESCH STD. & SPEC. 3.14):

A TEMPORARY BARRIER OR DAM WITH A CONTROLLED STORMWATER RELEASE STRUCTURE FORMED BY CONSTRUCTING AN EMBANKMENT WITH COMPACTED SOIL ACROSS A DRAINAGEWAY. SEDIMENT BASINS SHOULD BE USED ONLY FOR LARGER DRAINAGE AREAS, 3 ACRES OR GREATER.

BASIN(S) SHALL BE CONSTRUCTED AS A FIRST STEP IN ANY AND-DISTURBING ACTIVITY AND SHALL BE MADE FUNCTIONAL BEFORE UPSLOPE LAND

DISTURBANCE TAKES PLACE.

OUTLET PROTECTION (1992 VESCH STD. & SPEC. 3.18):

STRUCTURALLY LINED APRONS OR OTHER ACCEPTABLE ENERGY DISSIPATION DEVICES PLACED AT THE OUTLETS OF PIPES OR PAVED CHANNEL SECTIONS. OUTLET PROTECTION PREVENTS SCOUR AT STORMWATER OUTLETS, PROTECTS THE OUTLET STRUCTURES, AND MINIMIZES THE POTENTIAL FOR DOWNSTREAM EROSION BY REDUCING THE VELOCITY AND ENERGY OF CONCENTRATED FLOWS. THIS IS APPLICABLE TO THE

OUTLETS OF ALL PIPES AND ENGINEERED CHANNEL SECTIONS.

RIPRAP (1992 VESCH STD & SPEC 3.19):

A PERMANENT, EROSION-RESISTANT GROUND COVER OF LARGE, LOOSE, ANGULAR STONE WITH FILTER FABRIC OR GRANULAR UNDERLINING. TO PROTECT THE SOIL FROM EROSIVE FORCES AND SLOW THE VELOCITY OF CONCENTRATED RUNOFF.

VEGETATIVE PRACTICES

TEMPORARY SEEDING (1992 VESCH STD & SPEC 3.31):

THE ESTABLISHMENT OF A TEMPORARY VEGETATIVE COVER ON DISTURBED AREAS BY SEEDING WITH APPROPRIATE RAPIDLY GROWING ANNUAL PLANTS. TEMPORARY SEEDING REDUCES EROSION AND SEDIMENTATION BY STABILIZING DISTURBED AREAS THAT WILL NOT BE BROUGHT TO FINAL GRADE FOR A PERIOD OF MORE THAN 14 DAYS. TEMPORARY SEEDING REDUCES DAMAGE FROM SEDIMENT AND RUNOFF TO DOWNSTREAM OR OFF-SITE AREAS, AND TO PROVIDE PROTECTION TO BARE SOILS EXPOSED DURING CONSTRUCTION UNTIL PERMANENT VEGETATION OR OTHER EROSION CONTROL MEASURES CAN BE ESTABLISHED. FOR USE WHERE EXPOSED SOIL SURFACES WILL NOT BE AT FINAL GRADE FOR MORE THAN 14 DAYS. SUCH AREAS INCLUDED DENUDED AREAS, SOIL STOCKPILES, DIKES, DAMS, SIDES OF SEDIMENT BASINS, TEMPORARY ROADBANKS, ETC. (SEE MS#1 AND MS#2). A PERMANENT VEGETATIVE COVER SHALL BE APPLIED TO AREAS THAT WILL BE LEFT DORMANT FOR A PERIOD OF MORE THAN ONE

(1) YEAR.

PERMANENT SEEDING (1992 VESCH STD & SPEC 3.32):

THE ESTABLISHMENT OF A PERENNIAL VEGETATIVE COVER ON DISTURBED AREAS BY PLANTING SEED. PERMANENT SEEDING REDUCES EROSION AND DECREASES SEDIMENT YIELD FROM DISTURBED AREAS. PERMANENT SEEDING STABILIZES DISTURBED AREAS IN A MANNER THAT IS ECONOMICAL, ADAPTABLE TO SITE CONDITIONS, AND ALLOWS SELECTION OF THE MOST APPROPRIATE PLANT MATERIAL. PERMANENT SEEDING ALSO IMPROVES WILDLIFE HABITAT AND ENHANCES NATURAL BEAUTY. FOR USE IN DISTURBED AREAS WHERE PERMANENT, LONG-LIVED VEGETATIVE COVER IS NEEDED TO STABILIZE THE SOIL. FOR USE WHERE ROUGH-GRADED AREAS WILL NOT BE BROUGHT TO FINAL GRADE FOR ONE

(1) YEAR OR MORE.

MULCHING (1992 VESCH STD & SPEC 3.35):

APPLICATION OF PLANT RESIDUES OR OTHER SUITABLE MATERIALS TO THE SOIL SURFACE. MULCHING PREVENTS EROSION BY PROTECTING THE SOIL SURFACE FROM RAINDROP IMPACT AND REDUCING THE VELOCITY OF OVERLAND FLOW. MULCHING FOSTERS THE GROWTH OF VEGETATION BY INCREASING AVAILABLE MOISTURE AND PROVIDING INSULATION AGAINST EXTREME HEAT AND COLD. FOR USE IN AREAS WHICH HAVE BEEN PERMANENTLY SEEDED. MULCHING SHOULD OCCUR IMMEDIATELY FOLLOWING SEEDING. AREAS THAT CANNOT BE SEEDED BECAUSE OF THE

SEASON SHOULD BE MULCHED WITH AN ORGANIC MULCH.

SOIL STABILIZATION BLANKETS AND MATTING (1992 VESCH STD. & SPEC. 3.36):

THE INSTALLATION OF A PROTECTING COVERING (BLANKET) OR SOIL STABILIZATION MAT ON A PREPARED PLANTING AREA OF A STEEP SLOPE, CHANNEL OR SHORELINE. FOR USE ON SHORT, STEEP SLOPES WHERE EROSION HAZARD IS HIGH AND PLANTING IS LIKELY TO BE TOO SLOW IN PROVIDING ADEQUATE PROTECTIVE COVER; IN VEGETATED CHANNELS WHERE THE VELOCITY OF DESIGN FLOW EXCEEDS "ALLOWABLE" VELOCITY;

ON STREAMBANKS OR TIDAL SHORELINES WHERE MOVING WATER IS LIKELY TO WASH OUT NEW PLANTINGS; OR IN AREAS WHERE THE FORCES OF WIND PREVENT STANDARD MULCHING PRACTICES FROM REMAINING IN PLACE UNTIL VEGETATION BECOMES ESTABLISHED.

TREE PROTECTION (1992 VESCH STD. & SPEC. 3.38):

PROTECTION OF DESIRABLE TREES FROM MECHANICAL AND OTHER INJURY DURING LAND DISTURBING AND CONSTRUCTION ACTIVITY.

DUST CONTROL (1992 VESCH STD. & SPEC. 3.39);

TO PREVENT SURFACE AND AIR MOVEMENT OF DUST FROM EXPOSED SOIL SURFACES AND REDUCE THE PRESENCE OF AIRBORNE SUBSTANCES WHICH MAY PRESENT HEALTH HAZARDS, TRAFFIC SAFETY PROBLEMS OR HARM TO ANIMAL OR PLANT LIFE DURING LAND DISTURBING, DEMOLITION

AND CONSTRUCTION ACTIVITIES.

TEMPORARY AND PERMANENT STABILIZATION

DURING CONSTRUCTION, APPLY TEMPORARY AND/OR PERMANENT SEEDING AS GRADING OPERATIONS ARE COMPLETED IN AREAS NOT TO RECEIVE

PAVEMENT, OR OTHER IMPERVIOUS SURFACES.

POST CONSTRUCTION-APPLY TOPSOIL, PERMANENT SEEDING PER SPECIFICATIONS AND SOIL AMENDMENTS (AS NECESSARY) TO ALL DISTURBED

SURFACES NOT RECEIVING PAVEMENT OR OTHER IMPERVIOUS SURFACE.

TEMPORARY SEEDING SHALL BE APPLIED WITHIN SEVEN DAYS TO DENUDED AREAS THAT MAY NOT BE AT FINAL GRADE, BUT WILL REMAIN DORMANT FOR LONGER THAN 30 DAYS AND LESS THAN ONE YEAR. THIS INCLUDES, BUT IS NOT LIMITED TO, STOCKPILES AND BORROW AREAS.

PERMANENT SEEDING SHALL BE APPLIED AND A PERENNIAL VEGETATIVE COVERING SHALL BE ESTABLISHED ON DISTURBED AREAS WITHIN SEVEN DAYS OF BEING BROUGHT TO FINAL GRADE ON AREAS NOT OTHERWISE PROTECTED. SELECTION OF THE SEED MIXTURE SHALL DEPEND ON THE TIME OF YEAR

IT IS TO BE APPLIED.

MULCHING SHALL BE APPLIED TO ALL PERMANENT SEEDING IMMEDIATELY UPON COMPLETION OF SEED APPLICATION. MULCH LIBERALLY DURING THE

MID-SUMMER AND WINTER SEASONS.

SEE VIRGINIA EROSION AND SEDIMENT CONTROL TECHNICAL BULLETIN NO. 4, NUTRIENT MANAGEMENT FOR DEVELOPMENT SITES, FOR UPDATED SEED MIXTURES AND SCHEDULES AS WELL AS UPDATED LIMING, MULCHING, AND FERTILIZING REQUIREMENTS. SEE VIRGINIA EROSION AND SEDIMENT

CONTROL HANDBOOK STD. AND SPEC. 3.35 FOR MULCHING SPECIFICATIONS.
