This data represents the general service area of the place of use for organizations with water rights who qualify as municipalities or municipal providers under I.C. Title 42 or the 1996 Municipal Water Rights Act and who have a municipal water right on file at IDWR. The service area is for illustrative purposes. This data does not necessarily represent the boundary of city limits. Drainage Districts and Tribal boundaries are not represented in this data.This dataset is derived from the following queries of IDWR water right and recommendation databases: Status = Active, LPOU = Yes, And (WaterUse = Municipal or WaterUse = Municipal From Storage). A Large POU (LPOU) is a water right place of use for which the delivery of water is described with a digital boundary as defined by I.C. Section 42-202B(2) and authorized pursuant to I.C. Section 42-1411(2)(h). If a specific owner has multiple rights represented by different PlaceOfUseIDs, the PlaceofUseID representing the largest area is used. If there is significant divergence in location between different PlaceofUseIDs, the shapes are merged and PlaceofUseID of -999 is assigned.

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 is a polygon data set representing the current areas where sewer service is available to the public through the City of Boise sewer system and neighboring private sewer districts. The intention of this data set is not to show every single parcel that actually has sewer service, but rather to define the general boundaries of where sewer service is available. There are parcels using septic systems within the service area boundaries but these are not identified in this layer. The boundaries for the private sewer districts are included for delineation of service area responsibility. The data set was developed by the Engineering Division of the Boise City Public Works Department from parcel and sewer mainline data. This data set is continually being updated. The data set is current to the date it was published.

This is a polygon data set representing City of Boise annexations and de-annexations since the original townsite was established in 1866 by the Idaho Territorial Legislature.

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 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 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.
