Thurston GeoData CenterThis feature class is maintained by TCOMM911 in coordination with the addressing authorities of Thurston County Development Services and the Cities of Olympia, Lacey, Tumwater, Yelm, and Rainier. The intent of this data is to provide emergency services with the earliest address plan for new developments even while the development is under construction. Address points are placed on the structures using orthophotos. If the structure is not visible on the aerial the point is placed using the best available information as to where the structure is or will be located. Points are updated as new information is provided. Field Explanation: Zip Code and Zip Code Plus 4- generally accurate. Use with caution Building, Floor, Unit, Room, Seat- updated when information is available. Elevation is an rough approximation based on 1996 contour layer and adding roughly 10 feet for every floor.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/61ec0c7df77e4452ac614bfe88e4bfe6_0engThurston GeoData CenterPublicThurston Address Points TCOMM [Washington (State)--Thurston County]Web servicesWashington (State)--Thurston CountyWashington (State)Last Modified: 2025-05-05
