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

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.

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.
