Ada County Assessor's Office maintains the dataset of city limits within Ada County. It is comprised of city boundaries determined by taxcode and maintained continually, adding areas annexed to city limits by current ordinances.

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.

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.

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

This is a polygon data set representing the current Boise City Police (BPD) reporting districts. Police reporting districts are the smallest division of territorial boundaries used by law enforcement to deploy manpower, organize officers below their senior commanders, and to track reported crimes, accidents, and calls for service. Reporting districts typically encompass a few square blocks. Boise City Police reporting districts exist only within the Boise City limits. The outer boundary of the reporting districts are coincident with the Boise City limit boundaries. This data set was created by Boise City GIS based on boundaries determined by the Boise Police Department and Ada County Sheriffs Office. It is current to the date it was published.For more information, please visit Boise Police Department.

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. For more information, please visit City of Boise Fire Department.

This is a polygon data set that depicts the current fire inspection areas for Boise City. The Boise City Fire Department Inspectors are responsible for a variety of fire related activities including verifying that new, existing, or alteration of existing buildings within the Boise Area of Impact conforms to the fire codes established by the State and Boise City. The Boise City Fire Department Battalion Chiefs are the first officers in command of the Fire Suppression Divisions. The Boise City Fire Department divides areas of responsibility geographically, using the fire inspection polygons to determine which inspectors are responsible for a particular geographic area. There are two inspectors per inspection area. The fire inspection area boundaries subdivide the Boise City Area of Impact and external boundaries of the North Ada County Fire and Rescue (NACFR) district as determined by Boise Fire Department officials. This data set is continually being updated. It is current to the date it was published. For more information please visit City of Boise Fire Department

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 feature layer contains subdivision boundaries throughout Weld County and is sourced from Weld County’s GIS data hub. Plat PDFs are associated with most features as attachments in feature pop-ups. The dataset is intended to support the City of Greeley Community Development Department with planning, permitting, zoning evaluation, and development review processes. Although the dataset is originally created and maintained by Weld County GIS, it is periodically updated and republished by Greeley IT GIS for local use. This version is used internally by departments that rely on current subdivision data for land use planning, infrastructure coordination, and development tracking within the Greeley municipal boundary and surrounding Weld County areas. Potential users include Community Development, Public Works, Stormwater, Parks, Forestry, Emergency Management (Police and Fire), and Finance, among others who require accurate subdivision boundaries for analysis or planning purposes. The dataset is reviewed for accuracy but may reflect the update cadence and data structure provided by Weld County.
