CEPSCI Construction Site Best Management Practices 2

Question 1

What maintenance is required for silt fence to ensure it remains effective?

Accepted Answer

Regular inspection for tears, undermining, and sagging, plus sediment removal when accumulation reaches one-third of fence height

Answer

Silt fence must be regularly inspected for damage, and accumulated sediment must be removed when it reaches one-third of the fence height to maintain flow-through capacity and prevent overtopping.

Question 2

Where should silt fence NOT be installed?

Accepted Answer

In areas of concentrated flow such as drainage channels or swales

Answer

Silt fence is designed for sheet flow conditions only; in concentrated flow areas the hydraulic forces exceed the fence's capacity, causing it to fail and potentially creating a worse problem.

Question 3

A soil stockpile on a construction site should be managed by:

Accepted Answer

Surrounding it with sediment controls and covering it with mulch or tarps to prevent erosion

Answer

Stockpiles must be surrounded with sediment controls such as silt fence or berms and covered with mulch or tarps to protect exposed soil from rain erosion.

Question 4

What is the recommended maximum contributing drainage area for a standard silt fence installation?

Accepted Answer

0.25 acres per 100 linear feet of fence

Answer

Silt fence is designed for small drainage areas, typically no more than 0.25 acres per 100 linear feet of fence, because larger contributing areas generate flows that overwhelm the fabric's limited capacity.

Question 5

Vehicle tracking controls should extend from the paved road onto the construction site at least:

Accepted Answer

50 feet or until natural road surface is reached

Answer

A stabilized construction entrance should extend at least 50 feet from the paved road surface to allow vehicles sufficient travel distance to dislodge mud from tires before reaching pavement.
