City of Washington, DCStorm Drain Marker Installations is a data layer showing where storm drain markers were installed on storm sewer catchments. Markers indicate that the sewer catchments drain to the Chesapeake Bay watershed and to report pollution to DC's 311 service line. Markers are installed by DOEE and volunteer groups. This dataset should not be considered as a complete capture of all DC storm drains. There are some storm drains that are knowingly not included within this layer. Catchbasin ID refers to DC Water's ID for each storm drain.ArcGIS DynamicMapLayerhttps://hub.arcgis.com/datasets/22e954e7d625490f90c3ab7f486cb9cd_47engOpen Data DCPublicStorm Drain Marker Installations [District of Columbia--Washington]Web servicesDistrict of Columbia--WashingtonDistrict of ColumbiaLast Modified: 2024-10-25
