Stormwater Management

Most of these fact sheets apply to post construction stormwater management (PCSM). Two relate to during construction situations.

Design guidance provided for engineers and planners on how to properly develop a bioretention cell.

Guidance provided on how to develop effective runoff capture and reuse systems as part of a stormwater management plan.

The purpose of this fact sheet is to provide guidance on how green roofs can be constructed and how they can be expected to contribute to solving stormwater problems.

The purpose of this fact sheet is to provide guidance to stormwater designers about assessing a potential stormwater infiltration site to determine (1) how fast stormwater can be expected to infiltrate into the soil and (2) what depth of stormwater can be expected to enter the soil during each runoff event.

Across the country, public officials and others are focusing their pollution control efforts on stormwater management in both urban and rural areas. It is through stormwater that many pollutants, such as sediment, nutrients, bacteria, heavy metals, and others reach surface waters.

Information provided on how effectively various low impact development (LIDs) practices remove these pollutants from stormwater.

The skimmer is a sedimentation basin dewatering control device that withdraws water from near the basin’s water surface, thus removing the highest quality water from the basin for delivery to the uncontrolled environment.

Design criterion provided that can be used by engineers to properly size various dewatering control features used as part of the basin’s principal spillway.

Guidance provided about what a contractor needs to know to be able to properly build (or construct) an infiltration surface; the soil surface where stormwater or wastewater is expected to enter the soil profile.
