VESCP - ANSWERVirginia Erosion and Sediment Control Program
- Administered by counties/cities (must), towns (may)
- MUST BE APPROVED
,Minimum Standard 1 - ANSWERStabilization
permanent or temporary soil stabilization shall be applied to denuded areas within
seven days after final grade is reached on any portion of the site; temporary soil
stabilization shall be applied within seven days to denuded areas that may not be at
final grade but will remain dormant for longer than 14 days; permanent stabilization shall
be applied to areas that are to be left dormant for more than one year
Site NOT at Final Grade - ANSWER- stabilize in 14 days
- temporarily seed
- mulch
- permanently stabilize if dormant > 1 year
Site at Final Grade - ANSWER- stabilize in 7 days (recommended immediately)
- permanently or temporarily seed and mulch
- mulch/matting/straw
Minimum Standard 2 - ANSWERStock Piles, Waste and Borrow Areas
during construction, soil stock piles and borrow areas shall be stabilized or protected
with sediment trapping measures
mulch prevents erosion by protecting the surface from raindrop impact and silt fence
intercepts and detains from disturbed areas
Minimum Standard 3 - ANSWERPermanent Vegetation
permanent vegetation cover shall be established on denuded areas not otherwise
permanently stabilized (permanent vegetation shall not be considered established until
a ground cover is achieved that is uniform, mature enough to survive, and will inhibit
erosion *there is no % associated with this*)
reduce erosion and decrease sediment yield from disturbed area
this is the standard used to verify that a site is ready for release of bonds or surety
Minimum Standard 4 - ANSWERFirst-Step Measures
Sediment basins and traps, perimeter dikes, sediment barriers and other measures
intended to trap sediment shall be constructed as a first step in any land-disturbing
activity and shall be made functional before upslope land disturbance takes place
a certain amount of initial land disturbance may be required to provide access for
equipment to install the perimeter controls, but site clearing and grading should be kept
to a minimum until the perimeter controls are in place
, intercepts and detains small amounts of sediment from disturbed areas during
construction operation to prevent sediment from leaving the site and decrease velocity
of sheet flows and low-to-moderate level channel flow
Perimeter Controls - ANSWERassures that sediment does not leave the perimeter of
the land-disturbing area once site clearing, grading, and construction commences
Examples: silt fences, sediment traps, sediment basins, construction entrance,
temporary diversions, diversions
Minimum Standard 5 - ANSWEREarthen Structure Stabilization
stabilization measures shall be applied to earthen structures such as dams, dikes, and
diversions immediately after installation
reduce erosion and sedimentation and reduce damage from sediment and runoff to
downstream or off-site areas
Minimum Standard 6 - ANSWERTraps and Basins
sediment traps and basins shall be designed and constructed based upon the total
drainage area (not just disturbed area) to be served by the trap or basin
Sediment Traps - ANSWERminimum storage capacity shall be 134 cubic yards per acre
of drainage area and shall only control drainage areas less than 3 acres
*stone outlet = trap*
Sediment Basins - ANSWERsurface runoff from disturbed areas that is comprised of
flow from drainage areas greater than or equal to 3 acres shall be controlled by a basin;
minimum storage capacity of a sediment basin shall be 134 cubic yards per acre of
drainage area; the outfall system shall, at a minimum, maintain the structural integrity of
the basin during a 25-year storm of 24-hour duration; runoff coefficients used in runoff
calculations shall correspond to a bare earth condition or those conditions expected to
exist while the sediment basin is utilized.
Sediment Trapping Devises - ANSWER1. place near the lowest drainage points of a
project
2. install as a first-step measure [MS-4]
3. stabilize immediately [MS-5]
4. must include outlet protection for basins [MS-11]
