Parcels of Thurston County, Washington. Thurston County's data set for use in determining issues related to property ownership based on tabular information stored in the ASCEND and SIGMA databases maintained by the Thurston County Assessor's Department.

The fields SEWER_TYPE and WATER_SRC come from a variety of different sources and jurisdictions which the Assessor’s Office has no control of or the ability to audit. The Assessor’s Office appraisers are not experts in determining the exact type of water/sewer system available to a site, and do not make any official determination. These legacy fields are not updated. Local utility providers should be contacted for better information for specific parcels.

Thurston County, WA, US Post Office Box assigned zip codes. The purpose of this data is as a general reference only and actual mailing zip codes should be obtained from the US Postal Service. This layer was originally created using US Post Office Data. These points are associated with the US Post Office Box locations that house a unique Zip Code.This layer should be used in conjunction with the Zip Codes layer which is used to show zip code area boundaries associated with addressing and Thurston County Assessor’s Parcels. For example in smaller jurisdictions, like Bucoda, that rely on a post office box rather than rural delivery, the zip code point will reflect the unique zip code while the surrounding area will reflect the greater rural zip code boundaries and not the localized PO Box zip code.

This feature class is maintained 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.Street centerlines are initially digitized from center of right-of-ways shown on survey plats and are then updated when a new orthophoto becomes available. Unnamed roads, driveways, planned roads, alleys are only intended for graphic display. These segments are generally not topologically connected to addressed streets. This feature class is used as the street centerline source for TCOMM911 Operations Center (CAPCOM) CAD/Ti Geo file load and Maverick Map data. As of 1/06, edits in this data regarding exact street name and begin/end address ranges are also entered in the County's Master Street Address Guide through Intrado's 911Net database maintenance request site.Layer/Field Explanation:Street centerlines are initially digitized from center of right-of-ways shown on preliminary plats and updated in final survey plats. If this source is delivered in hard copy, then the document will be scanned and the image georectified using common parcel corners found in the source and in the County parcel layer. Some centerlines are imported directly from digital survey drawings. When a new orthophoto becomes available, the centerlines are reviewed again and adjusted and/or vertex weeded as necessary.Theoretical address ranges are used to extend valid ranges beyond physical addresses. This will influence the positional quality of geocoded points if used as a reference source. It should be noted that the County Development Services Addressing Department does not assign house numbers where the right two digits exceed the number 49. For emergency services, address ranges need to be continuous where the physical street is continuous and maintain 100 block interval changes at intersections. As a result, geocoded points are likely to be skewed toward the lower end of each address range.Zero address ranges will not be used on any name/addressed street types. Any named and signed road without address ranges will default to a 100-199 address range Speed Limit- This attribute was created using the best available information at the time. Use with caution. Limited access segments (I5 and US 101) have been assigned address ranges based on mile post location. Decimal house numbers are not valid so mile post address ranges have been multiplied by 100.CITY_L and CITY_R are used to define msag community, not postal community. Unincorporated areas and those within the City of Olympia are given the community of 'OL'. A list is posted to the County GeoData Center showing unique street names selected by all jurisdictions within the county for addressing officers to consult in selecting street names, http://www.geodata.org/capcom.aspx. Capcom's policy requires that new street names are unique regardless of jurisdiction and street type. Unnamed roads, unofficially named roads, driveways and alleys are identified as TYPE=5.Special characters in street names are not valid. Hyphens are generally replaced with a space character.Forest roads within Capitol Forest are being captured with proper WA DNR road identification based on DNR map. The address range applied to forest roads is based on distance in miles x 100 from the trunk in which branching road extends.

The main purpose of this data is used as part of road planning, road maintenance and analysis of county owned roads. This is accomplished by linking it to data from the County Road Information System. All other jurisdictional roads are kept up to date as we are notified of their change of status. This layer is also used for mapping the transportation infrastructure; Intercity Transit routes, Snow removal routes, School District transportation planning, and Fire District mapping, among others.

This data is a subset of the NRCS soils data (March 2007), as requested by Thurston County Development Services Long Range Planning. This data identifies soil types that support pocket gopher habitat and is intended for planning and conservation efforts. Text disclaimer for Gopher Soils per Thurston County Planning Department: All soils shown on the Mazama pocket gopher soils map are to be used to determine areas that could potentially be suitable for Mazama pocket gophers and their habitat. The soils are derived from the final Federal Rule regarding the listing of the Mazama pocket gopher, which is on file with the Resource Stewardship Department. This map is a screening tool of where Mazama pocket gophers or their habitat may be present. The map should not be used as a final indicator that gophers are present, or that gopher habitat exists on a specific property. Mazama pocket gophers can be found in other locations outside of the mapped areas. More information on Mazama pocket gophers can be obtained from the Thurston County Resource Stewardship Department website by going to www.thurstonprairiehcp.org, or by going to the U.S. Fish and Wildlife Mazama pocket gopher information page at https://www.fws.gov/wafwo/mpg.html.From the NRCS Soils Metadata: This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey area extent format and include a detailed, field verified inventory of soils and non soil areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. A special soil features layer (point and line features) is optional. This layer displays the location of features too small to delineate at the mapping scale, but they are large enough and contrasting enough to significantly influence use and management. The soil map units are linked to attributes in the National Soil Information System relational database, which gives the proportionate extent of the component soils and their properties.

Thurston County school attendance district boundaries. This layer is used to denote the attendance areas for elementary, middle and high schools in Thurston County. Data is updated with information provided by the school districts (Tumwater, North Thurston, etc) or their representative (Olympia/TRPC). Edits are made to be parcel specific where possible however due to parcel change over time they may not be coincident. This layer is used to inform the Thurston GeoData Center Online Parcel Information Page (nightly combo table process). Updated June 1, 2017 by kah

This data shows current (2010) park, public preserves, natural areas, and undeveloped lands for Thurston County, local cities, state, and federal ownership. The data also includes information about park amenities, size, address and owner information.LAST UPDATED: 27 SEPT 2017 by KLB

Dataset is a polygonal representation of structures within Thurston County. This data was derived from the 2000 aerial photography. Some of the buildings and structures may be distorted due to canopy interference. The data was derived from the AutoCAD entity layers. Each building type had an individual entity layer in AutoCAD, they were combined to create one GIS layer. This data layer was created by Smith and Associates from the 2000 imagery and delivered to GeoData around 2003. This data has not been updated since 2000 so changes to existing structures or additions since then will not be reflected in the data.
