Q1 According to the Virginia Erosion and Sediment Control Handbook (VESCH), what is the
minimum required buffer width for undisturbed natural vegetation along perennial streams?
Answer: 100 feet
Rationale: VESCH Section 3.2.3 requires a minimum 100-foot undisturbed vegetated buffer
along both sides of perennial streams and rivers unless site constraints make it impossible.
Q2 What is the primary purpose of a sediment trap?
Answer: To capture sediment from sheet flow before it enters a drainageway
Rationale: Sediment traps are temporary structures designed to intercept sediment-laden runoff
from small disturbed areas (typically <5 acres) and allow sediment to settle.
Q3 What is the maximum drainage area that can be treated by a single sediment trap?
Answer: 5 acres
Rationale: VESCH standards limit sediment traps to a maximum contributing drainage area of 5
acres.
Q4 When must a permanent vegetative cover be established on disturbed areas?
Answer: Within 7 days after final grading is complete
, Rationale: Virginia Erosion and Sediment Control Regulations (9VAC25-840-40) require
permanent stabilization within 7 calendar days after final grading.
Q5 Which of the following is NOT a required element of an Erosion and Sediment Control Plan?
Answer: Detailed cost estimates for all BMPs
Rationale: Virginia ESC regulations require a narrative, site plan, BMP details, and responsible
personnel, but not detailed cost estimates.
Q6 What is the minimum slope stabilization requirement for cut or fill slopes that exceed 3:1?
Answer: Use of erosion control blankets or matting
Rationale: VESCH recommends erosion control blankets or matting on slopes steeper than 3:1
to prevent rill and gully formation.
Q7 What is the required height of a silt fence post?
Answer: At least 36 inches above ground
Rationale: VESCH standard details require silt fence posts to extend a minimum of 36 inches
above the ground surface.
Q8 When inspecting a construction site, what is the first item the inspector should check?
Answer: Whether the approved ESC plan is on-site
Rationale: Virginia regulations require the approved ESC plan to be kept on-site at all times
during construction.
Q9 What is the maximum spacing between silt fence posts?
Answer: 8 feet
