VA DEQ SWM Inspector questions and answers
2026\2027 A+ Grade
Erosion and sediment control plans and stormwater management plans
- correct answer SWPPP plans that must be approved
Post-construction
- correct 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.
- correct answer Impervious cover
Target pollutant in the water quality criteria
- correct answer Phosphorus
The lower limit of the range of imperviousness that can result in stream degradation%
- correct answer 10%
SWM regulation ensures water quantity is considered to protect against which two destructive forces?
- correct 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.
- correct answer The rate of runoff
