This is a polygon data set representing parcels owned by the City of Boise as recorded in the Ada County, Boise County, or Canyon County parcel databases. The data for Ada County is derived from a periodic search of the Ada County Assessor’s parcel database for property that has ownership recorded as Boise City. Data for other counties is extracted when legal documents/deeds are received by Boise City GIS staff. The data is a snapshot of the City of Boise parcel ownership current to the last periodic update. The dataset is maintained by City of Boise GIS with input from the city’s departments to identify the department which owns or manages each parcel.

There are four entities within Ada County that assign addresses within their jurisdiction: Boise City, Ada County, Meridian, and Kuna. This dataset is an aggregation of key address data elements supplied by the four addressing entities into a single county-wide address point layer.Attribute Fields:AddPfx = Address Number Prefix: The non-integer portion of the identifier for the house, building or other feature that precedes the address number itself. Ex. 'NW'AddNum = Address Number: The numeric identifier for a land parcel, house, building or other feature. Ex. '1', '125'AddSfx = Address Number Suffix: The non-integer portion of the identifier for the house, building or other feature that follows the address number itself. Ex. '1/2'StPredMod = Street Name PreModifier: A word or phrase that precedes all other elements of the street name and modifies it, but is separated from the street name by a street name pre-directional and/or pre-type. Ex. 'Old'StPreDir = Street Name PreDirection: A word preceding the street name that indicates the directional taken by the thoroughfare from an arbitrary starting point, or the sector where it is located. Ex. 'N', 'SW'StPrefix = Street Name PreType: The element of the complete street name preceding the street name element that indicates the type of street. Ex. 'Ave', 'Blvd'StName = Street Name: Official name of a street as assigned by a local governing authority.

This maps shows City of Boise annexations since the original townsite was established in 1866 by the Idaho Territorial Legislature. Use the time-slider to watch the City grow over time. An annexation is the legal incorporation of a geographic area in to a political body. A de-annexation is the secession of a geographic area from a political body. De-annexed areas are areas that were once part of the incorporated boundaries of Boise City but have been removed from the incorporated boundaries (based on the ordinance tied to the de-annexation). The source of the data is the ordinances of annexation recorded by the Boise City Clerks' office. The map also depicts the current incorporated boundaries for cities within Ada County. The Ada County Assessor's Office maintains the city limits and impact areas datasets within Ada County. City boundaries are determined by taxcode and maintained continually, adding areas annexed to city limits by current ordinances. The impact areas dataset depicts the unincorporated areas of Ada County surrounding each city as identified in Title 9 of the Ada County Code, in accordance with Idaho Code Section 67-6526. This data is maintained by City of Boise GIS and is based on the legal descriptions contained in the ordinances. This data set is continually being updated as annexations occur. It is current to the date it was published.For more information, please contact the Ada County Assessor's Division of Land Records/GIS or the City of Boise Planning & Development Services division.

This is a line data set depicting preliminary subdivision parcel boundaries within the Boise City Area of Impact. These lines represent the subdivision lay out prior to final approval by the Ada County Assessor’s Office. Preliminary boundaries are subject to change. The preliminary subdivision data set is derived by Boise City GIS from AutoCAD files submitted by local engineering firms to Boise City. The preliminary subdivision is deleted from the Boise City preliminary data set when a subdivision is officially recorded and added to the Ada County basemap data. This data set is continually being updated by the Boise City GIS. It is current to the date it was published

Preliminary Plats and entitlements in Ada County and Canyon County. This map also contains parcel boundaries, and subdivisions to help determine the status of development.

This is a polygon dataset representing City of Boise Parks and Recreation managed foothill reserve data, based on the National Parks and Recreation Association (NRPA) GIS Data Model. This data set was created from a combination of Boise Parks and Recreation park and facility files and the Ada County Parcel records. This dataset was created by POWER Engineer's, Inc. and will be maintained by the City of Boise. This data set is updated at the request of Boise Parks and Recreation staff, as changes to the park data occur. It is current to the date it was published.For more information about Boise reserves, please visit City of Boise Parks & Recreation.

This is a polygon data set that depicts the locations of easements and vacations of easements granted to the City of Boise. An easement is a legal right to make use of land owned by another party, for a specific and limited purpose as specified within an easement description. An easement vacation is a legal declaration to relinquish to the parcel owner the easement that was formerly granted. Easements are attained by the City of Boise in the following ways: 1)through right-of-way vacation from Ada County Highway District where the City of Boise retains rights to build and maintain utility structures across the area vacated within the vacation description; 2)a Boise City Council resolution where a grantor gives the City the right to build and maintain sanitary sewer, geothermal, drainage or pressure irrigation across their property; 3)as a grant of easement or grant deed recorded at Ada County; and 4) as a note on a subdivision final plat that a specific lot, portion of a lot or lots is shown to have an easement across it (them) and may or may not include dimensions of the easement. All easements in this data set are within the Boise City Area of Impact. This data set is maintained by Boise City Public Works GIS staff. Features in this data set are derived from available computer aided drafting CAD drawings, paper map documents and legal descriptions that define easement locations. Easements have been granted to the City of Boise since about 1900 to the present. Documentation of easements prior to 1970 is incomplete; therefore most of the easements in this data set will be from 1970 to the present. The data is updated continuously. It is current to the date it was published.

This is a point data set of 1/10th milepost markers for trails along the Boise River from Lucky Peak Dam to the current terminus within the City of Eagle. The trails along the Boise River are generally referred to as ‘the greenbelt’. The milepost markers along the Boise River are collectively known as the Distance and Orientation Trail System (DOTS). Mileposts are a series of numbered markers placed along a route at regular intervals used as reference points. The DOTS divides the greenbelt trails into quadrants; north and south side of the Boise River, and east or west of the origin at the 8th Street pedestrian bridge in Boise, Idaho. Milepost identification is comprised of the quadrant or sector (i.e. NW for northwest, SW for southwest, NE for northeast, and SE for southeast) and a mileage (in tenths of a mile). For example, NE 3.1, indicates the north side of the river, and east of the 8th Street pedestrian bridge by 3.1 miles. There are several known exceptions to this convention. The milepost origin for the north and south trail origins are simply delineated by ‘N’ and ‘S’. Also, several mileposts are marked with a ‘W’ for West where the north and south trails converge. Mileage numbers increase as you move east and west from the 8th Street pedestrian bridge. Milepost markers are not always physically marked on the ground. This data set shows mileposts along the trail centerline and is not meant to represent the physical demarcation of the mileposts. Physical markers, if they exist, will be relatively nearby the point defined in this data set.This data set was created by City of Boise GIS team in cooperation with Boise State University based off of GPS data and heads up digitizing against available GIS trail and orthophotography data. The data has been reviewed by parks, police, and fire staff from several local agencies in Ada County. The data is believed to be generally accurate. This data set is updated irregularly as new GPS data is collected or as changes to the trail system in different jurisdictions occur. The data set is current to the last date of publication.For more information about the Boise River Greenbelt, please visit City of Boise Parks and Recreation.
