Erosion and Sediment Control
PREPARATION TEST 2026 QUESTIONS AND
CORRECT ANSWERS GRADED A+
● What is the largest non-point source pollutant in American
waterways? Answer: sediment
● Sediment and erosion mitigation on construction sites involves two
basic steps: Answer: minimizing the amount of land disturbed (erosion
control) and limiting the damage caused by sediments (sediment control)
● Erosion Control Answer: used to reduce or eliminate conditions that
lead to erosion
aimed at keeping soil in place
● Sediment Control Answer: used to minimize the off site transport of
sediments in runoff where and when erosion occurs
● 4 Causes for Erosion Answer: 1. soil characteristics
2. vegetative cover
3. topography
4. precipitation
, ● Erosion and sediment control plan should: Answer: - reduce the
detachment and transport of soil during site demolition and construction
- avoid centralized treatment, instead dispersing mitigation across site is
more effective and allows for some control devices to be retrofitted into
stormwater management practices
● 4 Principles of Erosion and Sediment Control Plans Answer: 1.
minimize disturbance
2. controlling runoff
3. collecting sediment
4. construction sequencing and monitoring
● How to minimize disturbance Answer: - create design that works with
existing topo
- limit footprint of new development
- properly managing site construction
- preserving existing vegetation (most effective)
● How to control runoff Answer: -should prevent runoff from crossing
disturbed or exposed soils, when not possible, vegetative buffer strips
should be used to reduce runoff velocities
- all runoff should be directed and routed to sediment control devices by:
1. review existing runoff patterns on their site prior to development
