What is the maximum drainage area allowed for a temporary sediment trap?

The maximum drainage area allowed for a temporary sediment trap is 5 acres. This limit is established to ensure that the trap can effectively manage and settle sediment from stormwater runoff before it enters larger water bodies. A sediment trap is designed to capture sediment and reduce erosion in construction sites or areas prone to significant runoff.

When the drainage area exceeds this limit, the effectiveness of the trap may decrease as it may not be able to handle the volume of water and sediment, leading to potential failures or insufficient sediment removal. Therefore, limiting the drainage area to 5 acres strikes a balance between effectiveness and manageable maintenance of the sediment control practice, ensuring that these traps continue to function as intended.
