Naturalized Detention Basin

A conventional detention basin is widely used to manage stormwater from development, but it has important limitations in terms of water quality, ecology, and community benefits. Detention basins usually capture stormwater using a series of inlets and pipes that collect drainage from nearby hardscapes, but are normally designed to manage runoff from only the largest storms and are less effective at reducing pollution. Turf-covered detention basins can be converted to native meadows through a variety of turf stripping and seeding methods. This can offer a cost effective option for meeting regulatory requirements if your project includes redevelopment areas, but note that naturalized detention basin does not currently appear in the NJ BMP Manual. Naturalized detention basins may look similar to infiltration basins or constructed wetlands, but are dry except during storms and do not include an engineered sand/soil bed.
