The Street Centerline dataset represents the key streets of Ada County, with associated address ranges. It does not show low-grade dirt roads in the deserts and foothills. It includes, for emergency dispatch purposes, some roads in Boise and Elmore Counties. This dataset was developed by many parties over many years. Credit should go to Geographic General (now Power Engineers), Spatial Dynamics, Ada Planning Association (now COMPASS), Ada County Sheriff's Office Emergency Dispatch, and Ada County GIS

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.

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 fire hydrants managed by Boise City. The term 'managed' is used in this data set to denote that Boise City maintains a mapped location of the fire hydrant to satisfy needs identified in the purpose section of this metadata. A fire hydrant is any fixture designed to enable firefighters to tap into the water distribution system to assist in extinguishing a fire. In the Boise region these are typically the traditional above ground cast iron hydrants (generally red) with a cap and valves. This data set also includes atypical hydrants such as the underground access points as found at the Boise Airport. This data set was created by Boise City GIS beginning in 2008 based on available information from United Water, Ada County, Garden City, Meridian, and hardcopy maps maintained by Boise Fire. The data is currently updated via GPS and heads-up digitizing (when GPS data is not available). This dataset is continually updated as new hydrants are installed and location or attribute errors are corrected. The data set is current to the last date of publication. This data set contains all fire hydrants in the following locales: 1) Boise City Limits/Boise Fire District and enclaves; 2) Whitney Fire District and enclaves; 3) North Ada County Fire and Rescue (NACFR) Fire District excluding Garden City; and 4) the general area five miles south and east of the Boise area of impact that are not within a fire district. No data is collected for the following areas: 1) Garden City limits or Garden City area of impact; 2) Kuna fire district; 3) Meridian fire district; and 4) Eagle fire district

Parcel boundaries are maintained by Ada County Assessor's office. Original basemap data consisted of high accuracy mapping at the center of Ada County where residential and incorporated areas existed. Plats of highways, subdivisions, surveys, and deeds have been added, along with new control and remapping efforts to add to the quality and accuracy of the parcels dataset.

Use the search bar to enter an address and see if that location is within the VTA's ADA Service Area.NOTE: For many addresses on Martha's Vineyard, the town which pops up with the address is often incorrect. This is due to how the massive address geo-locator database assigns town name. However, regardless of the incorrect town name label, the point located on the map is correct.For example, the correct address of 33 New York Ave, Oak Bluffs MA will appear in the search bar as 33 New York Ave, Vineyard Haven, MA, 02568, USA -- but the map will zoom to the correct location in Oak Bluffs.

This is a polygon dataset representing City of Boise Parks and Recreation data, based on the National Parks and Recreation Association (NRPA) GIS Data Model. A park is generally an area of land in a largely natural state, sometimes with grass, trees, paths, sports fields, playgrounds, picnic areas and other facilities, that is set aside and managed specifically for recreation use and enjoyment by the public. The features included in this polygon feature class are: parks and reserves.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 parks and reserves, please visit City of Boise Parks & Recreation.

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

This is a point data set of 1/10thmilepost 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 8thStreet 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 8thStreet 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 Boise City GIS 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.

This is a polygon data set representing fire district service areas within Ada County, Idaho. Fire districts are the administrative boundaries that define the area that a fire department, or contracted agency, is charged to provide fire suppression services for. It aggregates fire tax code area boundaries for fire districts and incorporated municipalities, as appropriate for the fire agency, to depict the service areas (a.k.a. districts) for each fire department/agency in Ada County. A fire district that annexes an area in June is responsible to serve that area even though taxation is not assigned to those properties until January the next calendar year. This data set does not represent areas of service defined through other agreements such as automatic aid, mutual aid, or other contractual agreements. This data set is not to be used to identify the tax district boundaries for any fire district/agency. The Idaho State Tax Commission publishes the official tax code area boundaries for all taxing districts (counties, cities, schools, libraries, recreation districts, fire protection, ambulance, hospital, mosquito abatement, and others) once a year (typically in March or April). This data set is maintained by Boise City GIS and is update at least twice a year (January and July). The data set is current to the date it was published.
