(Frequently Tested) with
Verified Answers
Erosion and sediment control plans and stormwater management plans - Answer: SWPPP plans that
must be approved
Post-construction - Answer: When the stormwater management plan address runoff
Volume and velocity of stormwater runoff increases as natural vegetation is replaced with these
surfaces. The increase in stormwater runoff leads to an increase in pollutants, such as sediment and
phosphorus that are carried to waterways. - Answer: Impervious cover
Target pollutant in the water quality criteria - Answer: Phosphorus
The lower limit of the range of imperviousness that can result in stream degradation% - Answer: 10%
SWM regulation ensures water quantity is considered to protect against which two destructive forces? -
Answer: Channel erosion and flooding
This increases after development because of the replacement of vegetation with impervious surfaces. A
larger volume of water will travel more quickly through a stream channel, potentially causing erosion
and flooding. - Answer: The rate of runoff
A what must be at least as stringent as the Construction GP (9VAC25-870-106)? - Answer: Locality VSMP
ESC Plan and SWM Plan (9VAC25-870-148) - Answer: Plans a locality's ordinance must require to be
