Question: 1 / 125
What is the storage capacity of a sediment basin?
1200 cf/acre
1500 cf/acre
1800 cf/acre
The correct answer regarding the storage capacity of a sediment basin is based on established guidelines for sediment control in construction and land disturbance activities. The standard practice for sediment basins typically specifies a minimum storage capacity of 1800 cubic feet per acre of drainage area. This amount is designed to effectively capture and retain sediment-laden runoff, allowing for the proper settling of sediment before the water is discharged from the basin.
This specification ensures that the sediment basin is sufficiently sized to handle rainfall events and maintain water quality, which is crucial for compliance with environmental regulations and for protecting downstream water bodies from sediment pollution. The other capacities listed, while they may represent theoretical values or be utilized in different contexts, do not meet the established standard for effective sediment retention for a sediment basin within the typical guidelines. Thus, 1800 cf/acre is the capacity that aligns with best practices in construction site management.
