The Urban Growth Area is used to manage future growth around densely populated areas. The urban growth area is the city/town and adjacent unincorporated growth area identified by the cities/towns/county to receive urban growth in the future. Outside of the boundary only rural growth is permissible.

Correction to this data can only be made through a Comprehensive Plan change or at the direction of Thurston County Long Range Planning due to a scrivener's error. The 1990 Washington State Growth Management Act requires the state's fastest growing cities and counties to designate UGAs around each city and town to accommodate the expected population growth over the next 20 years. In Thurston County, UGAs surround Bucoda, Lacey, Olympia, Rainier, Tumwater, Tenino, and Yelm. The current boundaries of the UGAs were established in 1990 and updated via the 2015 adoption of the Thurston County Comprehensive Plan: CHAPTER II - LAND USE II.URBAN GROWTH AREAS History and Purpose of Thurston County's Urban Growth Areas: In 1983, Thurston County, along with the cities of Olympia, Lacey and Tumwater, blazed the trail for growth management in Washington State by signing an interlocal government agreement called the "Urban Growth Management Agreement." That early agreement included an Urban Growth Management Boundary around the three cities to serve as a limit for the cities' expansion for 20 years. The purposes of the county's original growth areas remain relevant today: To provide for higher intensity development around the county's incorporated cities and towns and unincorporated community centers in order to concentrate development in areas where minimal impact to the environment, natural resources and rural atmosphere will occur. To minimize public costs and conserve energy by using services and facilities efficiently through concentration of development and integration of jobs, shopping, services and housing. To phase urban growth and infill with the provision of urban public services and facilities. One of the main effects of an urban growth area is to provide a limit for the extension of urban utilities, especially sewer service. To that end, overall residential density in urban growth areas should be high enough to support urban public services and to provide affordable housing choices. There should be a variety of housing types, with most densities ranging from 4 to 16 dwelling units per acre. Map M-14 identifies the urban growth areas for each city or town in Thurston County. The UGAs must accommodate the urban growth projected over the next 20 years including a reasonable market factor. Policies and actions emphasize the provision of urban land uses and services and include provisions specifically aimed at reducing low density residential sprawl. Joint plans established with each city and town include planning policies for each UGA. Joint plans are contained in separate documents, but are incorporated as part of the Thurston County Comprehensive Plan. Detailed land use designations for all UGAs around cities and towns are provided in the following joint plans (Map M-14 is keyed to the numbering below):Olympia/Thurston County Joint PlanLacey/Thurston County Joint Plan Tumwater/Thurston County Joint PlanYelm/Thurston County Joint PlanRainier/Thurston County Joint PlanTenino/Thurston County Joint PlanBucoda/Thurston County Joint PlanList of Map Correction's (Correction can only be made through a Comprehensive Plan change or at the direction of Thurston County Long Range Planning due to a scrivener's error.)Made on 5 AUG 2014 by KLW. Made on 15 July 2016 by KAH. - Correction of scrivener's error in Tenino UGA Boundary at the Teitge Annexations. This error was due to parcel and city mapping issues. The UGA has been fixed to be consistent with the parcel legal descriptions and the legal description included in the annexation ordinance approved by the City of Tenino, and the annexation approved by the Boundary Review Board.

This is the public land survey grid that shows sections for Thurston County. This data was originally acquired from Washington State Department of Natural Resources in, or around, the 1990's. No more specific time frame is available. This data was originally stored by the county in coverage format and was imported into SDE in 2011. No modification or changes have been made during this time however this layer is currently being reviewed by the Thurston County Surveyor. It may be changed once that review is complete. Use this layer with caution as it may or may not be spatially accurate.

Thurston County Basins and Watersheds. The watershed shapefile is created from the allbas coverage (basins) and shares the same metadata. This data is approved by the WA State Department of Ecology. The layer should be used as a general reference for basin delineation and not as an absolute.

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 layer is used as a general reference of boundaries associated with State and National Forest lands, Military installations, and Tribal lands in Thurston, and surrounding, counties. Every effort is made to update the boundaries as error's or changes occur however all changes are verified with a State or Federal entity before implementation. Military installations – All land associated with Joint Base Lewis McChord. Other properties owned by the Department of Defense, or similar entities, are not included in this layer.
State Forest Lands – All trust lands, managed by Washington State Department of Natural Resources, associated with Capitol State Forest. These encompass the approximately 100,000 acres of land in both Thurston and Grays Harbor counties. Other properties, owned by DNR, in Thurston County are not included in this layer. For Parks data (City, County, State, and Federal) and information see the Thurston County Parks layer.
National Forest Lands – National Forest lands, managed by the US Forest Service. Reservations – All lands associated with the Tribal Reservations of the Nisqually or Chehalis Tribes. This layer is updated using information from the US Federal Government as the authoritative source. This layer does not include lands in trust or lands falling outside the US recognized boundary.

Cities in Thurston County. This layer is generated from Annexations layer by automated process. Layer Updated, due to annexations, on October 31, 2017

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.

Maintained by TCOMM911 Thurston County Medic Zones divides the county into seven zones.

When the water and sewer systems were built, Thurston County worked with local property owners to identify which areas would be served by the systems. A payment-for-access boundary was drawn, and all properties within the boundaries were assessed to pay for construction of pipelines. This layer combines the formerly separate individual layers into one. Done on 30 JAN 2015 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.
