What is a common feature of sediment basins?

Sediment basins are specifically designed to capture and manage pollutants and sediment from stormwater runoff, making them an integral component of stormwater management systems. They serve to settle out suspended solids and reduce the amount of sediment that is discharged into receiving waters, thereby improving water quality. Their capacity to hold water temporarily allows for sedimentation to occur, which helps in filtering out various particles from the runoff.

In contrast to the other options, sediment basins are not necessarily permanent structures; many are temporary features used during construction projects to control sediment. They do indeed require maintenance to remove accumulated sediments and ensure proper functioning over time, and they are not limited to collecting only debris, as they also handle a range of particulates and pollutants from stormwater. This makes their role in stormwater management crucial, aligning perfectly with the correct answer.
