implications of stormwater models to develop a regional detention basin master plan for Fairfax County, Virginia are described. Following the selection of candidate sites and detention basin sizes for regional facilities, the SWMM/EXTRAN model was used to evaluate the watershed-wide impacts of alternate detention systems. To assess the regional benefits, various scenarios were analyzed, including different locational schemes and also oversized basins with lower maximum release rates to compensate for areas not controlled by regional facilities.
