Description: Best Management Practices (BMPs) are structural controls used to manage stormwater runoff. Examples include green roofs, rain gardens, and cisterns. BMPs reduce the effects of stormwater pollution and help restore the District’s waterbodies. The District’s stormwater regulations require that large construction or renovation projects install BMPs to manage stormwater runoff once construction is complete.
Description: The dataset contains planimetric features that are typically classified as impervious surface captured in 2010., created as part of the DC Geographic Information System (DC GIS) for the D.C.

Description: District MS4 Storm Sewer Outfalls. The dataset contains locations and attributes of the MS4 outfalls created as part of the Federal MS4 Permit. GPS outfall locations were captured by DC Water, then DC WASA in 2004-2006. A database provided by WASA identified outfalls, drainage structures, and MS4 outfall locations. The data was verified in conjuction between DOEE and DCWater. METADATA CONTENT IS IN PROCESS OF VALIDATION AND SUBJECT TO CHANGE.

Description: Storm Sewer Shed System areas. The dataset contains locations and attributes of storm sewer systems, created as part of the DC Geographic Information System (DC GIS) for the D.C. Office of the Chief Technology Officer (OCTO) and participating D.C. government agencies. This shapefile contains all storm sewer systems including the combined sewersheds within the DC WASA jurisdiction. There are small areas within this file, between regulators/interceptors and the outfalls, that primarily serve as storm sewersheds. Combined flow should enter these areas only when it overflows from the interceptors. METADATA CONTENT IS IN PROCESS OF VALIDATION AND SUBJECT TO CHANGE.
