    SPU DWW Drainage Basins

    Metadata Updated: November 29, 2025

    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. Drainage Basins areas were delineated using topography, roads and utility infrastructure based on current GIS data, 200-foot scale maps, side sewer cards and engineering design documents. Data source is DWW.drainage_basin_plgn_pv. Labels are based on the attribute NAME.Refreshed weekly.
