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.Permitted Use describes the intended use of the pipe, including Sanitary, Combined, or Drainage flows. Probable Flow takes into account upstream pipes and makes an assumption on the type of flow within the pipes.Proposed Mainlines are planned but not yet installed or as-built.SPU DWW Aba Rem Mainlines refers to Abandoned and Removed Mainlines.Force Mainlines are Mainlines under pressure. Detention Lines and Polygons refer to Mainline Detention Infrastructure.The data is refreshed weekly and is maintained by the SPU GIS Data Maintenance Team.

Displays areas with 40% steep slope or greater in the City of Seattle.A polygon feature class showing areas with an incline of 40% or more (10 feet of vertical rise over a horizontal distance of 25 feet or less) with a height of at least 10 feet. This layer was produced using a combination of 2001 LIDAR contours (Puget Sound LIDAR Consortium) and the 1993 topographic contours from aerial photos. The Steep Slope layer was most recently updated under SDCI Director's Rule 12-2019. The steep slope area map is called “advisory” because the mapping is used by the Seattle Department of Construction and Inspections for initial information and screening. Whether or not a site is eventually treated as an environmentally critical area is based on the actual topography of the ground surface. For more information about the definition of steep slope erosion hazard areas, see Seattle Municipal Code section 25.09.012, Environmentally Critical Areas (ECA) definitions. Because of the size of this dataset, we do not recommend trying to download it. Please use as a service.

City of Seattle 2 ft contours derived from Lidar captured in 2021. Contour lines display at 2ft, 10ft and 50ft intervals dependent on scale. Lines have been smoothed and generalized for display and performance.

Development Detail:

This vector tile service includes topographic contour lines representing elevation at 2-foot intervals within the city of Seattle.

The contours were derived from a bare earth - digital elevation model (DEM) with a pixel resolution of 1.5 feet. The lidar data that created the DEM were collected by NV5 Geospatial over the spring and summer months of 2021 and provided to the city by King County in 2022.

The DEM used to generate the contours was filtered using the Focal Statistics tool in ArcGIS, which served to limit some abrupt changes in cell values. A 3x3 rectangular neighborhood analysis was applied and a mean value was calculated per raster cell.

After running the Focal Statistics tool, 2-foot contours were generated from the filtered DEM. To reduce file size and improve performance, the contours were generalized further using the Smooth Line tool in ArcGIS. A smoothing algorithm type of Polynomial Approximation with Exponential Kernel (PAEK) and a smoothing tolerance of 20 feet was selected in the Smooth Line tool parameter options.

Finally, after executing both generalization tools (Focal Statistics and Smooth Line), all lines less than 25 feet in length were omitted from the final output.

Please note: The 2-foot contours are intended to be used for general reference and cartographic purposes only and should not be used for analysis purposes.
