This shapefile includes the annexation polygons that the Office of Financial Management (OFM) has sent to the Census Bureau since March 2020 as part of the Boundary and Annexation Survey (BAS). The Census Bureau uses these polygons to update Washington State’s city limits. Field names follow Census BAS guidelines, and an outline of relevant field names is below. More information about BAS can be found here: https://www.census.gov/programs-surveys/bas.html

The polygons include the quarterly annexations and other boundary corrections that effect the Census city boundaries, as well as several county boundary adjustments for King, Kittitas, Pierce, Spokane, and Stevens County. The annexation polygons were originally created by Washington’s Department of Transportation, and then edited by OFM to align with the latest BAS city boundary file available. These polygons to not follow the strict legal description of the annexation, as their intent is to make clear delineations between jurisdictions for population allocation. The following are the main differences between BAS annexation polygons and the originals:

<!--· The edges and vertices of polygons are snapped first to contiguous Census city limits and then to county parcels

<!--·
Where an annexation moves a city boundary to be either adjacent or across a right of way, the polygon is drawn to the centerline of the right of way

<!--· Annexations that are only include a right of way are often omitted, as they will not change the Census Bureau boundary

This file is updated quarterly. For questions or for data from earlier years, please contact Nate Chase nate.chase@ofm.wa.gov.

Relevant Field Names:

<!--·
CHNG_TYPE- Type of area update. A is annexation, D is deannexation, and B is a boundary correction which is a newly discovered boundary discrepancy

<!--· Eff_date- the local effective date

<!--· AUTHYPE- O is ordinance or resolution; X is for boundary correction; L signifies a county boundary correction

<!--· DOCU- the legal ordinance or resolution for the annexation. If there is a blank, then the entry is a correction polygon.

<!--· RELATE- Changing from in or out of jurisdiction

<!--· JUSTIFY- OFM’s reason for submitting the change polygon

<!--· A_Date- this is the date that OFM approves the annexation. OFM cannot legally approve annexations until all state requirements are met. The approval date cannot be earlier than the effective date, but it can be on the same day. OFM’s population determinations use the approval date of annexations. BAS submissions are only submitted after this date.

Neighborhood council boundaries for the City of Spokane

The GIS Commissioner District layer depicts three County Commissioner districts for Spokane County. This layer was developed from Federal Census Blocks rectified to fit Spokane County GIS base layers.

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.
