Urban Stormwater & Construction

Urban areas have a high concentration of impervious surfaces. Rainwater running off impervious surfaces such as roads, parking lots, and roofs can pick up pollutants and carry them into stormdrains and then to rivers, streams, and lakes.

Construction sites are a major source of erosion and sediment problems if BMP's are not used correctly. Construction takes place both inside and outside of urban area and so is considered separately from urban area stormwater. Erosion from construction sites can be up to 200 times that of agricultural lands.


The MDEQ is designated as the lead agency for implementing an urban polluted runoff control program including the Stormwater Program. The MDEQ regulates most construction activities. More local communities are also regulating construction activities, especially those communities with Phase II permits. (see EPD General Permits Branch)


The Mississippi Department of Transportation is responsible for implementation of erosion and sediment control practices on highway construction.

Solutions to urban and construction pollution problems are well developed and understood. Both structural and nonstructural Best Management Practices (BMPs) protect disturbed areas from rainfall and flowing water. To learn more about BMP's to control polluted runoff, view these links.
