Urban Stormwater Management


  • EPA has created a new web-based tool to provide stormwater professionals with easy access to approximately 220 studies which assess the performance of over 275 stormwater Best Management Practices (BMPs). The tool provides access to studies covering a variety of traditional and low impact BMP types, including retention and detention ponds, biofilters, grassed filter strips, porous pavement, wetlands, and others. Users will also find a series of essays aimed at improving understanding of BMP performance and the importance of volume reduction/infiltration in these assessments. EPA plans to add more studies over the coming year, focusing on expanding the collection of studies of low impact development or green infrastructure BMPs. The Urban BMP Performance Tool can be accessed at http://www.epa.gov/npdes/urbanbmptool

  • EPA - Stormwater BMP Performance webcast featuring nationally known experts. The webcast NPDES website http://www.epa.gov/npdes/npdes-training . EPA's Urban BMP Performance Tool provides detailed information on the state of scientific research into the performance of stormwater BMPs. The instructors discussed a wide variety of factors, including pollutant removal, volume reduction, costs, and many other factors that should be considered when selecting permanent (post-construction) stormwater BMPs. The webcast compares three common BMP types (traditional wet and dry ponds and newer Green Infrastructure techniques, such as bioretention). The presenters discussed the advantages of the Green Infrastructure BMPs, particularly their ability to reduce the volume of stormwater discharged to rivers, lakes, and coastal waters.
