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.

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.

The Tacoma, WA Meter Urban Land Cover (MULC) dataset was generated from 1-meter image pixel resolution data sourced from 2011 USDA National Agricultural Imagery Program (NAIP) four band (red, green, blue and near infrared) aerial ortho-imagery. LiDAR point density data (9/m^2 point spacing), available for years 2010 and 2011, was used to map most areas of Pierce County, and supplemental LiDAR data, available for earlier years, was used to map area segments where 2010-2011 LiDAR data was not available. A 7-band stack consisting of 1-meter, four-band (red, green, blue, and near-infrared) aerial photography, Normalized Difference Vegetation Index (NDVI), and lidar-derived intensity and height above ground was created and primarily used to classify land cover using Genie Pro automated feature extraction software. Several ancillary datasets, such as hydrographic and transportation feature data, were edited in ArcGIS and integrated into the classification workflow. The Tacoma, WA land cover dataset includes data for the Tacoma metropolitan area of Pierce County, WA, and encompasses a total approximate area of 1,995 square kilometers. The thematic landcover data is confined to areas included within the US Census Bureau's 2010 Urban Statistical area boundaries for Pierce County, WA, with an additional 1km buffer extension that include bits of Kitsap, King and Thurston Counties. The following seven land cover classes were mapped: Water, Impervious, Soil or Barren, Trees or Forest, Grass or Herbaceous, Woody Wetlands and Emergent Wetlands. Mapped water bodies were generated using combined high-resolution LiDAR and ancillary hydrological data. Integrated wetland features were derived using ancillary National Wetlands Inventory (NWI) polygon data (version 2), downloaded from the Unites States Fish and Wildlife Service (USFWS) Wetland Mapper web mapping service (https://www.fws.gov/wetlands/data/mapper.html). Metadata for the NWI wetlands data layer can be found at http://www.fws.gov/wetlands/Data/Metadata.html. An accuracy assessment of the classified product, using 482 completely random and 46 (Soil/Barren) stratified random photo-interpreted land cover reference sample points yielded an overall user's accuracy (MAX) of 85.1 percent and a fuzzy user's accuracy (RIGHT) of 86.9 percent. For data workflow processing details see Overview Description section. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (http://enviroatlas.epa.gov/EnviroAtlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service.
