Description: Last updated on 12/19/2025 by WE.This data shows the designated mineral resource lands in Thurston County. This dataset is based on underlying geology and other factors that may support the commercial extraction of minerals. The basis of analysis was WADNR's 24 and 100K geology data that was adjusted to Thurston County 2011 LiDAR. Thurston County contracted Associated Earth Science,Inc.(AESI) to identify and classify mineral resources in the County and create a base inventory map showing the location of mineral resources. Resource classification (for example, A1, B3, etc.) for sand and gravel (aggregate) and quarry rock was made based on quality, quantity and other information derived from Thurston County, Washington State and Federal sources.Sand and Gravel(Aggregate)Resource Stratadecreasing resource qualityNon-ResourceQuality Type AQuality Type BQuality Type CQuality Type DDecreasing resource thickness and volumeQuantity Type 1•<5 percent fines•70:30 to 30:70 sand and gravel ratio•>25 years’ life expectancy•Minimum 240,000yd3/acre•>100 feet thick•Minimum overburden•Up to 15 percent fines•70:30 to 30:70 sand and gravel ratio•>25 years’life expectancy•Minimum 240,000 yd3/acre•>100 feet thick•Minimum overburden•Up to 25 percent fines•70:30 to 30:70 sand and gravel ratio•>25 years’ life expectancy•Minimum 240,000yd3/acre•>100 feet thick•Minimum overburden•Generally unsuitable for extraction •>25 percent fines, may have high organic content•Out of 70:30 to 30:70 sand and gravel range•No life expectancy•<15,000 yd3/acre•Limited depthQuantity Type 2•<5 percent fines•70:30 to 30:70 sand and gravel ratio•10 to 25 years’ life expectancy•Average 80,000 to 240,000 yd3/acre•50 to I00 feet thick•Overburden <15 feet thick•Up to 15 percent fines•70:30 to 30:70 sand and gravel ratio•10 to 25 years’ life expectancy•Average 80,000 to 240,000 yd3/acre•50 to 100 feet thick•Overburden <15feet thick•Up to 25 percent fines•70:30 to 30:70 sand and gravel ratio•10 to 25 years’ life expectancy•Average 80,000 to 240,000 yd3/acre•50 to 100 feet thick•Overburden <15 feet thickQuantity Type 3•<5 percent fines•70:30 to 30:70 sand and gravel ratioLife expectancy variable, generally <10 years•Average 15,000 to 80,000 yd3/acre•Thickness varies, typically <50 feet•Up to 15 percent fines•70:30 to 30:70 sand and gravel ratio•Life expectancy variable, generally <10 years•Average 15,000 to •80,000 yd3/acre•Thickness varies, typically <50feet•Up to 25 percent fines•70:30 to 30:70 sand and gravel ratio•Life expectancy variable, generally <10 years•Average 15,000 to 80,000 yd3/ acre•Thickness varies, typically<50 feetQuarry Rock (Bedrock) Quality Type AQuality Type BQuality Type CQuality Type DDecreasing interbedded resource strataType 1• Formation generally well mapped and (or) high percentage of formation contains resource strata of type AMeets or exceeds WSDOT specs for all rock products• Minimal amount of fractures•Minimal percent waste rock•20 percent or more rockery- size material produced•Formation mostly divided locally and contains a high percentage of resource strata of type B•Meets WSDOT specs for some rock products•Fractures vary from minor to very prevalent•Up to 10 percent waste rock• 20 percent or less rockery-size material produced•Formation mostly divided locally and contains a high percentage of resource strata of type C•Rock will not meet WSDOT specs•Highly fractured•10 to 30 percent waste rock•Minimal rockery-size material produced•Generally unsuitable for extraction•>30 percent waste rock•Highly to very highly fractured and (or) weathered and (or) poorly lithified•No rockery-size material producedType 2None•Formation undividedand >50% of formation contains mostly resource strata of type B as defined for Type 1 bedrock•Formation undividedand >50% of formation contains mostly resource strata of type C as defined for Type 1 bedrockType 3•Formation undividedand <50% formation contains mostly resource strata of type B as defined for Type 1•Formation undividedand <50% of formation contains mostly resource strata of type C as defined for Type 1The mineral resource inventory was adopted on November 12, 2019 with Resolution 15836 as Map N-3.The mineral resource inventory was then used as a basis to create the mineral resource lands designation. Designated mineral resource lands were determined through evaluation of the mineral resource inventory data based on location and parcel size considerations. Areas were added or removed from the inventory based on the guidance from the Thurston County Board of County Commissioners, Planning Commission, and input from the public. These included: Proximity to public preserves, parks, national wildlife refuges, state conservation areasProximity to Cities, Urban Growth Areas, and Federal or Tribal LandsLocations of transportation rights of wayLocations of Thurston County historic sitesLocations of previously designated and current permitted mining locationsParcel size threshold of a minimum of 5 acres in sizeParcel adjacency where more than 40% of the surrounding parcels are less than 5 acres in sizeInformation regarding the analysis processes is included in the Metadata Lineage and in documentation stored by the Thurston County Community Planning and Economic Development.

Description: Last updated on 7/29/2019 by KAH.Shoreline Master Program Designations for Thurston County effective May 15, 1990.The Shoreline Master Program requirement, including subsequent amendments, is a result of the Shoreline Management Act (SMA). The Shoreline Management Act of 1971, Chapter 90.58 Revised Code of Washington (RCW) was adopted by the citizens of Washington in 1972. The overall goal of the SMA is to “prevent the inherent harm in an uncoordinated and piecemeal development of the state’s shorelines.” This act is designed to provide for three broad polices: (1) protect shoreline natural resources and ecological functions, (2) reserve shorelines for water dependent and associated water-related uses, and (3) promote public access.Local SMPs are adopted under guidelines established by Ecology, as defined in WAC 173-26. These guidelines allow local planners to tailor SMP goals, policies, standards and regulations to the specific needs of individual communities. In addition, the SMP is also meant to be used to provide comprehensive planning for the County’s shoreline area (RCW 90.58.030(3)(b)).Master programs must contain a system to classify shoreline areas into specific environment designations. The classification system must be based on the existing use pattern, the biological and physical character of the shoreline, and the goals and aspirations of the community as expressed through comprehensive plans as well as the criteria in this section [WAC 173-26-211 (2)(a)]. Environment designation assignment to shoreline reaches must assure the protection of existing shoreline ecological functions with the proposed pattern and intensity of development as well as be consistent with policies for restoration of degraded shorelines [WAC 173-26-211 (4) (b)].Future development located within shoreline jurisdiction needs to be consistent with the rules and policies within the shoreline environment designation, as well as local government zoning and critical area regulations. Ecology guidelines require critical area protection within shoreline jurisdiction to be - at a minimum - equal to the protection provided under the currently adopted local critical area ordinance WAC 173-26-221(2)(b)(ii),(iii) and (c) and provide for “no-net-loss” of ecological function.This layer is used as a screening tool and the information is based upon the Shoreline Master Program for the Thurston Region Effective May 15, 1990. Layer Schema was updated in 2019 to allow for changes to the layer based upon changes to the Shoreline Master Plan to incorporate updates/fixes as well as changes that have been approved by Ecology over time. This schema change allows for the tracking of "historic" polygons which are shown in the Feature Class and not carried through to the shapefile. Details about the nature of the historic change are included. When using this layer it is important to use the filter Historic = "No" in mapping and analysis.

Description: Last updated on 6/20/2023 by SLS.Thurston County Hydro/Stream data originated as coverage file representation of the Thurston County hydro network. It included all waterbodies: rivers, lakes, ponds, inlets and streams. The features were digitized by the Thurston GeoData Center from the Thurston Comap, Assessor's Data dated 1990, and Tiger Files using rubber sheeting and aerial digitizing. Attribute information, including DNR Classifications and Naming, originated from Washington State DNR and Department of Ecology. In 2002-2003 the data was updated along Marine Shorelines using updated Aerial Photography. In 2011 the hydro coverage file were converted into feature class files during which process stream and river data was separated from other waterbodies; large river areas, lakes, ponds, and marine areas. The datasets were renamed to Streams and Waterbodies respectively. In 2014 some minor adjustments were made to both layers in the Lake Lawrence area as the result of LiDAR derived hydro enforced DEM data. Other changes that have been made to the data include Stream Name/Attribute information. These changes are made when authoritative information is received from USGS GNIS in regards the naming or renaming of streams. Future plans are in place for revisions to the data to more accurately reflect waterbody locations.

Description: Last updated on 12/19/2025 by WE.DNR HYDRO supports many agency programs and mandates and is available to the public. Agency uses include state base maps; landscape analyses and modeling; the Family Forest Fish Passage Program; landslide mapping; the Sustainable Harvest Calculation; fire protection; the Natural Heritage Program; and the Trust Forestland HCP water typing system. DNR HYDRO is also used for Forest Practices water typing. The dataset serves as the Forest Practices Water Type Map. The Forest Practices water typing system is used in the planning and regulation of forest practices on state and private forest land. Forest Practices water types (WAC 222-16-031) are intended for DNR Forest Practices regulatory purposes only.The DNR water course (WC), water body (WB), and water shoreline (WS) datasets, collectively known as DNR HYDRO, make up the most up-to-date hydrography layer for the state of Washington. WC represents water courses as arcs or lines. These occur alone as single arcs representing streams, ditches, or pipelines, or as centerlines through water body polygons such as double-banked streams, lakes, impoundments, reservoirs, wet areas, or glaciers. WB represents water bodies as polygonal features. WB includes features such as Puget Sound, lakes, wet areas, reservoirs, impoundments, glaciers, islands, and dams. WS represents shorelines as polygon perimeter arcs. The WC and WBWS are edited daily and simultaneously; updates are posted weekly for internal DNR use and monthly for external use. Attribute interrelationships within the WC and within the WBWS and spatial and attribute interrelationships between the WC and WBWS are maintained. Routes can be built on the WC by using the whole stream identifier (WC_LLI D_NR). DNR HYDRO is continually updated through the DNR Forest Practices Water Type Modification Form process. DNR HYDRO is mixed scale. The nominal scale is considered 1: 24,000, but some data at larger scales are included.

Description: Last updated on 3/4/2016 by KAH.This data is a subset of the NRCS soils data (March 2007), as requested by Thurston County Community Planning and Economic Development Department. This data identifies soil types that support pocket gopher habitat and is intended for planning and conservation efforts. Text disclaimer for GopherSoils per Thurston County Community Planning and Economic Development 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 Community Planning and Economic Development 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 Community Planning and Economic Development Department website by going to www.thurstonprairiehcp.org, or by going to the U.S. Fish and Wildlife Mazama pocket gopher information page at http://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 nonsoil 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.

Description: This data contained in this layer is from c. 1995 and originated from the Washington State Department of Natural Resources (DNR). It was implemented in GeoData's SDE on 4/25/2017. According to the DNR's metadata, there are no planned updates. GeoData will check the available data from DNR periodically to ensure that we have the most current version of data in case that changes.The DNR Forest Practices Wetlands Geographic Information System (GIS) Layer is based on the National Wetlands Inventory (NWI). In cooperation with the Washington State Department of Ecology, DNR Forest Practices developed a systematic reclassification of the original USFWS wetlands codes into WAC 222-16-035 types. The reclassification was done in 1995 according to the Forest Practice Rules in place at the time. The WAC's for defining wetlands are 222-16-035 and 222-16-050.Supplemental information:The reclassification is based on the USFWS FWS_CODE. The FWS_CODE is a concatenation of three subcomponents: Wetland system, class, and water regime. Forest Practices further divided the components into system, subsystem, class, subclass, water regime, special modifiers, xclass, subxclass, and xsystem. The last three items (xsomething) are for wetland areas which do not easily lend themselves to one class alone. The resulting classification system uses two fields: WLND_CLASS and WLND_TYPE. WLND_CLASS indicates whether the polygon is a forested wetland (F), open water (O), or a vegetated wetland (W). WLND_TYPE, indicates whether the wetland is a type A (1), type B (2), or a generic wetland (3) that doesn't fit the categories for A or B type wetlands. WLND_TYPE = 0 (zero) is used where WLND_CLASS = O (letter "O"). The wetland polygon is classified as F, forested wetland; O, open water; or W, vegetated wetland depending on the following FWS_CODE categories:F O W---------------------------------------------------------------Forested Open VegetatedWetland Water Wetland---------------------------------------------------------------PFO* POW PUB5E2FO PRB* PML2PUB1-4 PEM*PAB* L2US5PUS1-4 L2EM2PFL* PSS*L1RB* PML1L1UB* L1AB*L1OWL2RB*L2UB*L2AB*L2RS*L2US1-4L2OW-------------------------------------------------------------------------* indicates inclusion of the subcategory (ie.

Description: Last updated on 4/25/2017 (layer published in SDE).This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the conterminous United States. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of "farmed wetlands" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps.
