Geospatial data about Spokane County, Washington Municipal Boundaries. Export to CAD, GIS, PDF, CSV and access via API.

A precinct is generally the smallest level of geography established for purposes of conducting elections. Each precinct has a specific location where its residents go to vote.

The "Shoreline Jurisdiction" shall refer to the shoreline areas of the Spokane River and Latah Creek within the Spokane City limits where the Shoreline Regulations shall apply, the general boundaries of which are illustrated on the Shoreline Jurisdiction Map, SMC 17E.060.060. In the event that any of the boundaries on the Shoreline Jurisdiction Map conflict with the criteria of WAC 173-22-040 as amended, the criteria shall control. The Shoreline Jurisdiction shall include: 1. All water bodies and land underlying these water bodies within the City of Spokane qualifying as "shorelines of the state," pursuant to the SMA, RCW 90.58.030(2)(c). In the City of Spokane, shorelines of the state are the Spokane River and Latah Creek within the Spokane City limits; 2. All upland areas, also referred to as "shorelands," that extend 200 feet landward in all directions on a horizontal plane from the edge of the ordinary-high-water mark of the Spokane River and Latah Creek within the Spokane City limits; and 3. Any associated wetlands, floodways, and some or all of the 100-year floodplain, including all wetlands within the 100-year floodplain of the Spokane River and Latah Creek within the Spokane City limits.

Boundary describes the extent of the Spokane Valley-Rathdrum prairie aquifer from south end of lake Pend Oreille, Idaho - thru Rathdrum Prairie, the Spokane Valley, turning north to discharge at little Spokane River, and Spokane river north and west of the city of Spokane. Source data overview:Spokane Valley aquifer (WA State only) digitized in 1988 by Spokane Co. Engineer Dept from USGS 1977 hydrologic study of the Spokane Aquifer. This layer digitized from 1:24000 quad maps into the County's GDMS GIS. The USGS relied heavily on contour lines that described the valley floor to delineate the Spokane aquifer boundary. The original boundary had the Spokane River as it's west edge, but was revised (by Bea Leckaff Spokane County WQMP-GIS) in June, 1994, under the direction of Stan Miller to include the flood plain terraces on the west side of the river, down to the Little Spokane River confluence. The extent of the aquifer was revised again in March, 1995 to reflect new information from CH2MHill aquifer studies being done for the City of Spokane (to support Wellhead Protection). The revised aquifer extends the influence of impervious basalt outcroppings from the Spokane Falls area to the Trinity Triangle, (Drumheller Springs). The corrections were made by BBL from information provided by Stan Miller.

Idaho Portion of the Aquifer data came from Idaho Panhandle Public Health GIS SCALE: Idaho data digitized originally from 1:24000 USGS maps LAST UPDATED: March 1993- received Idaho data and matched to Spokane county aquifer data.

Business Improvement Districts (BIDs) are adopted by City Ordinance and guided by sections of the Spokane Municipal Code. These districts generally include the assessment of dues or fees paid by property owners to the BID fund, which are then used for the provision of certain programs that foster greater success for local businesses and services as well as (sometimes) the planning, construction, and maintenance of certain public improvements and infrastructure.

This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). The National Wetlands Inventory - Version 2, Surface Waters and Wetlands Inventory was derived by retaining the wetland and deepwater polygons that compose the NWI digital wetlands spatial data layer and reintroducing any linear wetland or surface water features that were orphaned from the original NWI hard copy maps by converting them to narrow polygonal features. Additionally, the data are supplemented with hydrography data, buffered to become polygonal features, as a secondary source for any single-line stream features not mapped by the NWI and to complete segmented connections. Wetland mapping conducted in WA, OR, CA, NV and ID after 2012 and most other projects mapped after 2015 were mapped to include all surface water features and are not derived data. The linear hydrography dataset used to derive Version 2 was the U.S. Geological Survey's National Hydrography Dataset (NHD). Specific information on the NHD version used to derive Version 2 and where Version 2 was mapped can be found in the 'comments' field of the Wetlands_Project_Metadata feature class. 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. This dataset should be used in conjunction with the Wetlands_Project_Metadata layer, which contains project specific wetlands mapping procedures and information on dates, scales and emulsion of imagery used to map the wetlands within specific project boundaries.
