With Correct Answers
VESCP |- |CORRECT |ANSWER✔✔-Virginia |Erosion |and |Sediment |Control |Program



- |Administered |by |counties/cities |(must), |towns |(may)

- |MUST |BE |APPROVED



Minimum |Standard |1 |- |CORRECT |ANSWER✔✔-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 |ANSWER✔✔-- |stabilize |in |14 |days

- |temporarily |seed

- |mulch

- |permanently |stabilize |if |dormant |> |1 |year



Site |at |Final |Grade |- |CORRECT |ANSWER✔✔-- |stabilize |in |7 |days |(recommended |immediately)

- |permanently |or |temporarily |seed |and |mulch

- |mulch/matting/straw



Minimum |Standard |2 |- |CORRECT |ANSWER✔✔-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 |ANSWER✔✔-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 |ANSWER✔✔-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 |ANSWER✔✔-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 |ANSWER✔✔-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 |ANSWER✔✔-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 |ANSWER✔✔-minimum |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 |- |CORRECT |ANSWER✔✔-surface |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 |- |CORRECT |ANSWER✔✔-1. |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]



Minimum |Standard |7 |- |CORRECT |ANSWER✔✔-Cut |and |Fill |Slopes



roughening |the |surface |of |the |slope |decreases |runoff, |lowers |the |velocity |runoff, |increases |
water |retention, |and |leads |to |better |seed |germination



slopes |that |are |found |to |be |eroding |excessively |within |on |year |of |permanent |stabilization |shall
|be |provided |with |additional |slop |stabilizing |measures |until |the |problem |is |corrected




Minimum |Standard |8 |- |CORRECT |ANSWER✔✔-Concentrated |Runoff



shall |not |flow |down |cut |or |fill |slopes |unless |contained |within |an |adequate |temporary |or |
permanent |channel, |flume |or |slope |drain |structure
