,The polygons are intended for use by the City of Seattle as planning-level tool for a preliminary understanding of the drainage patterns in particular areas of the City. The layer is not complete and does not reflect any City determination about how specific locations should be characterized. The delineation was based on drainage, land use, type of waterbody, and neighborhoods. Displays data from DWW.receiving_wtrbdy_plgn_pv with the following data query: RWB_NAME <> 'Urban Combined System'. Labels are based on the attribute NAME. This layer does not display when zoomed out beyond 1:400,000.,Refreshed weekly.,

,This layer displays the urban creek watersheds. Creek watershed flow is in the contentious and intermittent natural surface water flow identified and recognized as a stream by the Seattle Public Utilities. The polygons are intended for use by the City of Seattle as planning-level tool for a preliminary understanding of the drainage patterns in particular areas of the City. The layer is not complete and does not reflect any City determination about how specific locations should be characterized. Creek watersheds were delineated using topography, utility infrastructure and field verification. The data source is DWW.urban_crk_wtrshd_plgn_pv. The layer does not display when zoomed out beyond 1:200,000. Labels are based on the attribute ALT_NAME and NAME, and do not display when zoomed out beyond 1:50,000. Refreshed weekly. Maintained by SPU USM.,

,This layer displays the urban watercourses showing open stream channels and flow within culverts, drainage laterals, and drainage mainlines. The Washington State Department of Natural Resources typing code for channel and fish use and the WRIA (Washington State Department of Ecology Water Resource Inventory Area) code are included. Displays data from DWW.stream_ln_pv symbolized on the attribute FEATYPE. The layer has the following definition query, STRM_EXPIRATION_DATE IS NULL. The data will not display when zoomed out beyond 1:200,000. Labels are based on the attribute SHORT_NAME and will not display when zoomed out beyond 1:50,000.,Refreshed weekly. Maintained by DWW Maintenance staff and USM.,

SPU DWW Mainlines is a Group Layer containing all Lifecycles, Ownerships, and other variations of Drainage and Wastewater Mainlines. The Connected Mainlines are symbolized differently in two different layers, one displaying the Permitted Use of the pipe and another displaying the Probable Flow.,
