Roadway crossings of natural waterways in the urban setting can be used as Best Management Practices (BMP's) by retrofitting existing outlet structures. Pollutant removal is contingent on inundation of a portion of the flood plain to provide extended detention. The design parameters, namely the detention basin storage and withdrawal rate, should be chosen to maximize the detention time within practical limits. An analytical procedure is formulated for preliminary planning estimates of the design parameters.
