Surface drainage points are structures that help direct rainwater in the City’s sub-surface pipe drainage system. The informal drainage system makes up nearly one-third of the City of Seattle footprint. This layer displays connected surface drainage points, regardless of ownership, that cannot be found in other layers. For example, Catch Basins, Junction Boxes, Sandboxes, and Inlets are not included. The data source is DWW.surface_drainline_pt_pv with the following data query: SDP_LIFECYCLE_TEXT IN ( 'Connected' , 'Unknown' , 'Temporary' ,'To Be Connected', 'Under Construction', 'Provisionally Connected', 'Proposed', 'Abandoned', 'Abandoned Temporary', 'Removed') AND SDP_FEA_TYPE_TEXT IN ( 'Area Drain;Area Way;Driveway Drain' ,'Cleanout', 'Flow Control MH' , 'Infall' , 'Maintenance Hole' , 'Overflow MH' , 'Other' , 'Rubber Coupler' , 'Reducer' , 'Surface Cleanout' , 'Sedimentation Chamber;Sand Catcher;Sand Trap' , 'Stand Pipe' , 'Weephole', 'Catch Basin MH', 'Vault', 'Underground Injection Cell; Drilled Drain'),

,The classification of SPU infrastructure in the City of Seattle and the former service area north of the City limits into areas of piped flow where storm water flow is either separated, partially separated, or combined with sanitary flow. An area with separated flow means that drainage flow is in drainage pipes only. A partially separated area means that some pipes are present that have both drainage and sanitary flow. A combined area has all pipes carrying sanitary and drainage flow.,Static dataset.,

SPU DWW Mainline Points is a Group Layer containing all Lifecycles, Ownerships, and other variations of Drainage and Wastewater Mainlines Points.,

,The Central Valley Flood Protection Plan (CVFPP) recommends that the California Department of Water Resources (DWR) develop a system for tracking performance of the flood system, including the following actions:,• Track the outcomes from flood investments to demonstrate value.,• Monitor and track outcomes of multi-benefit projects over time.,• Create a tracking system of operations and maintenance investments and outcomes to demonstrate the value that Local Maintaining Agencies attain for their investments.,• Track and report changes in the hydrologic and sea level rise conditions and subsidence over time through updates to the Flood System Status Report (FSSR),These recommendations stem from progressive work during the development of the 2012 CVFPP and subsequent 2017 CVFPP update. The DWR Flood Performance Tracking System tracks the CVFPP outcomes related to: (1) improving flood risk management and (2) enhancing ecosystem vitality. This tracking system has the ability to track the status, trends, and changes over time of the ecosystem (including the Conservation Strategy’s Measurable Objectives [CSMOs] as of 2016) outlined in the Conservation Strategy document here: https://cawaterlibrary.net/wp-content/uploads/2017/10/ConservStrat-Nov2016.pdf along with the Flood System metrics outlined in the Flood System Status Report here: https://water.ca.gov/Programs/Flood-Management/Flood-Planning-and-Studies/Central-Valley-Flood-Protection-Plan.,The associated data are considered DWR enterprise GIS data, which meet all appropriate requirements of the DWR Spatial Data Standards, specifically the DWR Spatial Data Standard version 3.1, dated September 11, 2019.,This data set was not produced by DWR.
