It is known that historical data from prior to the 1980s was inconsistently recorded and therefore the information reflected in this dataset may not be complete and should be used with discretion.

Primary Fire Protection District Boundaries are approved and downloaded from the Idaho State Tax Commission. Sub-Districts are not utilized or maintained at the State Level.DONNELLY RURAL FIRE PROTECTIONDonnelly Rural Fire Protection Sub-Districts were digitized manually from a Sub-District pdf map sent from fire chief Juan Bonilla in September of 2017. Valley County GIS Analyst confirmed with Juan that continuation of the East-West Boundary runs parallel to the Eastern and Western edges of the primary district and that once Dawn Dr. Boundary line hits the northern portion of Cascade Reservoir the line continues straight South to the Southern edge of the primary boundary.MCCALL FIRE PROTECTIONSub-Districts were redistricted in 2022 based on 2020 census population data.CASCADE RURAL FIRE PROTECTIONSub-Districts were redistricted in 2023 based on 2020 census population data.

This dataset was created for Boise Fire specifically to support network analysis, routing, and other spatial analysis needs for response time analysis and master planning for evaluating station location. This data set is catered to the Boise Fire Department needs and should not be used for general mapping purposes. For general mapping of fire stations use the regional fire facility data set. The regional fire facility data includes all fire facilities (i.e. training, administration, stations, storage) in Ada and Canyon county.

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.

The downloadable ZIP file contains an number of Esri shapefiles as described below. This data set provides the spatial information used to complete a post fire inventory and assessment for the 2015 Tepee Springs Fire in Idaho County, Idaho. The fire burned 95, 708 acres within Idaho County, Idaho in August 2015. Data was prepared by several agencies including US Forest Service, USDA Natural Resources Conservation Service, US Geological Survey, and the Nez Perce Soil and Water Conservation District. Data was prepared for the North Central Idaho Wildfire Restoration Group as part of their efforts in preparing the North Central Idaho Wildfire Inventory and Assessment Report (2015).Several data sets are available and are described as follows:Burn Severity: This data set reflects the fire burn severity and classifies intensity in to three categories.

This is a polygon data set representing first due areas for stations located in Ada County. A first area is geographical area that one station is closer to than any other station. It should normally be served by the personnel and apparatus from the fire station in the event of a fire or other emergency. With today’s computer aided dispatch (CAD) systems, station first due areas are no longer used to assign an apparatus to an incident. The closest engine, no matter the district, will be assigned. We now use the first due areas to analyze if our fire fighting force is being used efficiently. We will use it to see if certain stations are busier that others and if stations have a concentration of a specific type of call in their first due area. This information will be used to make business decisions within all fire departments in Ada County. The data set was created from FireView Desktop software based on current street network, station locations, and fire district boundaries. The accuracy is unknown. This data was created by the City of Boise. This data is updated as needed. It is current to the date of publication.

Note that pile burning (burning of previously "gathered" or "piled" materials) is not included on this map. The Forest Service and BLM use the most current and complete data available. GIS data and product accuracy may vary. They may be: developed from sources of differing accuracy, accurate only at certain scales, based on modeling or interpretation, incomplete while being created or revised, etc. Using GIS products for purposes other than those for which they were created, may yield inaccurate or misleading results.

PUBLIC VIEW - Aerial Hazards - includes: Powerlines, Visual Route Boundaries, Aerial Recreation Sites, Wind Farms, Towers, Repeaters and Base Stations, Wire Crossings, Bridges, and other misc hazardsThese are non-editable Fire map information for use with the Idaho BLM Fire Management Plan (FMP). This Feature Service contains data that are not intended for active editing and will require regular yearly updates.Idaho Fire FMP Aerial Hazards includes Flight hazards that can manifest themselves in many different forms including man-made obstacles and some environmental obstructions. Most notably are the Antenna Towers and Overhead Wires Antenna Towers: Numerous skeletal structures such as radio and television antenna towers exceed 1,000' or 2,000' AGL, Most skeletal structures are supported by guy wires which are very difficult to see in good weather and can be invisible at dusk or during periods of reduced visibility. Additionally, new towers may not be on your current chart because the information was not received prior to the printing of the chart. Overhead Wires: Transmission and utility lines often span approaches to runways, natural flyways, such as lakes, rivers, gorges, and canyons, and cross other landmarks pilots frequently follow such as highway, railroad tracks, etc.Supporting structures such as guy wires exist here as well. Other non-marked hazards exist as well such as the Instrument Route Boundary, Visual Route Outer Boundary, Aerial Recreation Area, and Air Refueling route. Though these are not visibly marked on the ground they are areas of extreme danger.included within the Aerial Hazards Feature Service: Powerlines, Visual Route Boundaries, Aerial Recreation Sites, Wind Farms, Towers, Repeaters and Base Stations, Wire Crossings, Bridges, and other misc hazards
