GPS outfall locations were captured in 2004-2006 by, then, DC WASA.  A database provided by WASA identified outfalls, drainage structures, and MS4 outfall locations. The data was later verified in conjunction between DOEE and DCWater along with field verification.  Updates occur as needed.   This data is used for planning and modeling purposes by various District programs.  This data is a requirement of the District's MS4 Permit.</SPAN></P><P><SPAN>Outfall ID Identification:</SPAN></P><P><SPAN>0-1999 - Originally provided outfall IDs</SPAN></P><P><SPAN>2000-2999 \u2013 Outfalls discovered from GIS and map analysis and later field verified</SPAN></P><P><SPAN>3000-3999 \u2013 Outfalls discovered during field work but with no additional info available</SPAN></P><P><SPAN>4000-4999 \u2013 Outfalls that can not be found in the field or cannot be verified</SPAN></P></DIV></DIV></DIV>", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://maps2.dcgis.dc.gov/dcgis/rest/services/DCGIS_DATA/Environment_Stormwater_Management_WebMercator/MapServer/68", "format": "ArcGIS GeoServices REST API", "mediaType": "application/json", "title": "ArcGIS GeoService"}, {"@type": "dcat:Distribution", "accessURL": "https://maps2.dcgis.dc.gov/dcgis/services/DCGIS_DATA/Environment_Stormwater_Management_WebMercator/MapServer/WMSServer?request=GetCapabilities&service=WMS", "format": "OGC WMS", "mediaType": "application/vnd.ogc.wms_xml", "title": "OGC WMS"}, {"@type": "dcat:Distribution", "accessURL": "https://opendata.dc.gov/api/download/v1/items/03795a44b05f41a1ae9d46a59a9227d8/csv?layers=68", "format": "CSV", "mediaType": "text/csv", "title": "CSV"}, {"@type": "dcat:Distribution", "accessURL": "https://opendata.dc.gov/api/download/v1/items/03795a44b05f41a1ae9d46a59a9227d8/geojson?layers=68", "format": "GeoJSON", "mediaType": "application/vnd.geo+json", "title": "GeoJSON"}, {"@type": "dcat:Distribution", "accessURL": "https://opendata.dc.gov/api/download/v1/items/03795a44b05f41a1ae9d46a59a9227d8/kml?layers=68", "format": "KML", "mediaType": "application/vnd.google-earth.kml+xml", "title": "KML"}, {"@type": "dcat:Distribution", "accessURL": "https://opendata.dc.gov/api/download/v1/items/03795a44b05f41a1ae9d46a59a9227d8/shapefile?layers=68", "format": "ZIP", "mediaType": "application/zip", "title": "Shapefile"}, {"@type": "dcat:Distribution", "accessURL": "https://opendata.dc.gov/datasets/DCGIS::ms4-storm-sewer-outfalls", "format": "Web Page", "mediaType": "text/html", "title": "ArcGIS Hub Dataset"}], "identifier": "https://www.arcgis.com/home/item.html?id=03795a44b05f41a1ae9d46a59a9227d8&sublayer=68", "issued": "2019-03-26T15:24:53.000Z", "keyword": ["D.C.", "DC", "District", "District of Columbia", "MS4", "Outfalls", "Storm Sewer", "Washington", "drainage area", "environment", "rain", "storm"], "landingPage": "https://opendata.dc.gov/datasets/DCGIS::ms4-storm-sewer-outfalls", "license": "https://creativecommons.org/licenses/by/4.0", "modified": "2026-02-06T00:00:00.000Z", "publisher": {"name": "City of Washington, DC"}, "spatial": "-77.1120,38.8060,-76.9117,38.9920", "theme": ["geospatial"], "title": "MS4 Storm Sewer Outfalls"}
