VESCP - Correct Answers ✅Virginia Erosion and Sediment
Control Program
- Administered by counties/cities (must), towns (may)
- MUST BE APPROVED
Minimum Standard 1 - Correct Answers ✅Stabilization
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 - Correct Answers ✅- stabilize in 14
days
- temporarily seed
- mulch
- permanently stabilize if dormant > 1 year
Site at Final Grade - Correct Answers ✅- stabilize in 7 days
(recommended immediately)

- permanently or temporarily seed and mulch
- mulch/matting/straw
Minimum Standard 2 - Correct Answers ✅Stock 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 - Correct Answers ✅Permanent
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 - Correct Answers ✅First-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 - Correct Answers ✅assures 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 - Correct Answers ✅Earthen
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 - Correct Answers ✅Traps 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 - Correct Answers ✅minimum storage
capacity shall be 134 cubic yards per acre of drainage area
and shall only control drainage areas less than 3 acres
