County Boundary

Water Mains are pipes that distribute water from a water supply system.

The geology of Spokane County and vicinity, Washington and Idaho was compiled from Carrara and others (1995), Joseph (1990), Kiver and others (1979), Miller (written communication, 1995), and Waggoner (1990a, b) for input into an Arc/Info geographic information system (GIS). The digital geologic map database can be queried in many ways to produce a variety of derivative geologic maps.

This data set was developed to provide geologic map GIS of the Coeur d'Alene 1:100,000 quadrangle for use in future spatial analysis by a variety of users. These data can be printed in a variety of ways to display various geologic features or used for digital analysis and modeling. This database is not meant to be used or displayed at any scale larger than 1:100,000 (e.g. 1:62,500 or 1:24,000).

The digital geologic map of the Coeur d'Alene 1:100,000 quadrangle was compiled from preliminary digital datasets [Athol, Coeur d'Alene, Kellogg, Kingston, Lakeview, Lane, and Spirit Lake 15-minute quadrangles] prepared by the Idaho Geological Survey from A. B. Griggs (unpublished field maps), supplemented by Griggs (1973) and by digital data from Bookstrom and others (1999) and Derkey and others (1996). The digital geologic map database can be queried in many ways to produce a variety of derivative geologic maps.

This GIS consists of two major Arc/Info data sets: one line and polygon file (cda100k) containing geologic contacts and structures (lines) and geologic map rock units (polygons), and one point file (cda100kp) containing structural data.

Welcome to the Spokane Regional Bike Map! SRTC and local jurisdictions have joined together to share local bike routes and infrastructure.By panning and zooming to different areas of the map, users can see the array of bicycle facilities available throughout the region.By clicking on either a Line or Point feature on the map such as the various bike routes, trail-heads, bike shops, park and ride locations, and other facilities you can view a pop-up with more information as well as additional links. Among the line attributes included are the posted speed limit, slope/steepness percentages and length in miles of each segment to assist you with determining the safety of the route you choose.The facilities displayed on this map are based on the best data available. The facilities are updated after each yearly construction season. The information in this map will continue to be updated as facilities are added or modified and as staff time allows throughout the year.Disclaimer: This map is not intended to be an exact representation of routes or an indication of the conditions the bicyclist may encounter. The bicyclist assumes the risks encountered and is advised to ride safely, use good judgment, and obey traffic laws on all routes, regardless of their designation on this map.

Donation sent to the University of Idaho Library Government Documents Librarian a CD containing General Land Office maps on it. A readme file on the CD contains this information:"I obtained the attached GLO maps from Mitch Price at River Design Group who obtained them from another source. These maps apparently do not have a date, I assume it was stripped off when they were rectified. These maps show the Great Northern Rail line, it arrived in Bonners Ferry in 1892. The Spokane International Railroad (Union Pacific purchased this line) built a bridge across the Kootenai R. in 1906." "I am a bit puzzled on the map dates, the Kootenai River Master Plan indicated these maps are 1862-65 but they also show the Great Northern Rail line but not the Spokane International Railroad which seems to place them somewhere between 1892 - 1906 unless perhaps they were revised at a later date."Gary Barton USGS Tacoma, WA 253-552-1613 officegbarton@usgs.gov

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.

Polygons representing the zoning designations for the City of Spokane. The data is updated regularly to reflect the current municipal code and associated amendments. See the following link for more information: https://my.spokanecity.org/smc/?Title=17C

This dataset provides the Planned Bikeway Network designations as apopted with the Master Bike Plan for the City of Spokane Comprehensive Plan on June 8, 2009 per ordinance C34424.

The Target Investment Areas are based on qualified US Census tracts as defined by the Community Development Financial Institutions Fund (CDFI) of the US Treasury for the New Markets Tax Credit program (NMTC). The Target Investment Areas represents those Census tracts identified as “Distressed” under the NMTC. Note, these areas are set by agencies outside the City of Spokane.

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.

Contains the data compiled from the questions asked of all people and about every housing unit. Population items include sex, age, race, Hispanic or Latino origin, household relationship, household type, household size, family type, family size, and group quarters. Housing items include occupancy status, vacancy status, and tenure (whether a housing unit is owner-occupied or renter-occupied).For a full description of data fields see: http://www.census.gov/prod/cen2010/doc/sf1.pdf

Fire Hydrants are devices to obtain water from the main supply, consisting of a barrel, connections for hose, and a valve assembly.

Spokane Regional Transportation Council (SRTC) and a multi-jurisdictional Working Group have spent the last two years updating a Congestion Management Process (CMP). A CMP is a systematic and regionally-accepted approach for managing congestion that provides accurate, up-to-date information on transportation system performance and assesses alternative strategies for congestion management that meet state and local needs. SRTC has the responsibility of implementing this process, with the assistance of other area jurisdictions as dictated by federal requirements. At a regional level the CMP helps inform and guide the agency’s investments as they pertain to congestion.The Congestion Management Plan was approved by the SRTC Board on December 11, 2014.

For more information, please view the report of the CMP process by clicking here.

According to the Federal Highway Administration (FHWA),

Congestion management is the application of strategies to improve transportation system performance and reliability by reducing the adverse impacts of congestion and the movement of people and goods. A congestion management process (CMP) is a systematic and regionally-accepted approach for managing congestion that provides accurate, up-to-date information on transportation system performance and assesses alternative strategies for congestion management that meet state and local needs. To access FHWA website on their Congestion Management Process click here.

A CMP is required in metropolitan areas with population exceeding 200,000, which are known as Transportation Management Areas (TMAs). The CMP is not a stand-alone document; it is meant to be incorporated into the metropolitan transportation planning process. In TMAs designated as ozone or carbon monoxide non-attainment or maintenance areas, "federal law prohibits transportation projects that result in a significant increase in carrying capacity for single-occupant vehicles (SOVs) from being programmed in these areas unless the project is addressed in the regional CMP“ (FHWA).

Rathdrum Comprehensive Aquifer Management Area Plan (CAMP) boundary of the Spokane Valley-Rathdrum Prairie Aquifer clipped at the Idaho border. Original 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. Spokane Valley aquifer (WA State only) was originally 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. It was modified in June 1994 by Spokane County WQMP-GIS and again in March 1995 based on data from additional aquifer studies conducted by CH2Mhill. The Idaho portion of the Aquifer data came from Idaho Panhandle Public Health GIS in March 1993. The Aquifer boundary was redrawn based on new data from a coordinated ground and surface water monitoring program conducted in 2004-2005. The study reassessed the hydrogeology and water budget of the Spokane Valley-Rathdrum Prairie Aquifer (Aquifer). Data was originally digitized at a 1:24000 scale.

The downloadable ZIP file contains an Esri shapefile. This is a bathymetric data set of Coeur d'Alene Lake, Coeur d'Alene River, St. Joe River, and Spokane River. This data was derived from bathymetric contour lines created by Parametrix, Golder and USGS. The contour lines were interpreted by the ArcGIS using the "Topo to Raster" tool to produce raster surfaces (i.e. Digital Elevation Model (DEM)). For most of the project area the contour lines had a one-foot increment. The only exception to this was when USGS data was used for areas around the Lateral Lakes along the Coeur d'Alene River. Five-foot contour lines were then generated from the DEM. Contour attribute is displayed in feet above sea level.The original data sets used for the basis of this project were created for various studies of Coeur d'Alene Lake. Primarily, in relation to the re licensing of the Post Falls dam. This dataset was created to try to avoid many of the edge matching issues that arose around the original Parametrix data set. This data set will also be used to generate future contour lines of the lake and rivers.These data were contributed to INSIDE Idaho at the University of Idaho Library in 2004.
