Fire Management Agreement Area

This dataset shows the boundaries of the province's six fire management zones that existed prior to 2014 in which most forest fires received the same type of response. These management zones were based on: Common forest and forest fire management objectives land use density of values at risk fire load forest ecology The 2014 Wildland Fire Management Strategy moved from a zone-based approach to one where each wildland fire is assessed and receives an appropriate response according to the circumstances and condition of the fire.  Additional DocumentationFire Management Zone - Data Description (PDF)  Fire Management Zone - Documentation (Word)   StatusCompleted: Production of the data has been completed  Maintenance and Update FrequencyAs needed: Data is updated as deemed necessary  ContactAviation, Forest Fire and Emergency ServicesAFFES.GIS@ontario.ca

This layer contains the data for the fire response areas in Durham County, North Carolina and the surrounding area. This layer is part of an original dataset provided and maintained by Durham City/County GIS Services and the City of Durham Fire Department. It is updated quarterly as municipal annexations are effective and as needed. The data in this layer are represented as polygons.

A fire protection class, also referred to as an ISO rating or a PPC rating, is determined for a fire department, based on that department’s performance in a series of evaluations conducted by the Office of the State Fire Marshal (OSFM). OSFM also evaluates a given area to determine an ISO rating or PPC rating it will attribute to that area based on that area’s proximity to a fire department/fire station and the available water supply in the geographical area. This layer visualizes the ISO/PPC rating for the fire department identified as the fire responsible agency for the given address. This rating may differ from OSFM’s rating for geographical area of the given address. The data is maintained and regularly updated by the City of Durham Fire Department to ensure accuracy and reliability.

The Fire Responsible Agency is the fire department (municipality, county, township, etc.) that serves as the primary emergency response agency for the given physical address. Additional agencies are often simultaneously dispatched to a given address in the event of an emergency. For example, within the city limits of Durham, North Carolina, the Durham Fire Department is the responsible agency. However, there are also areas outside of the city limits and/or located in Orange or Chatham County where Durham Fire Department is the responsible agency via inter-local contractual agreement. The data is maintained and regularly updated by the City of Durham Fire Department to ensure accuracy and reliability.

Fire Hazard Severity Zones (FHSZ) Fire Hazard Severity Zone classes from the map dated September 29, 2023, as adopted on January 31, 2024 and implemented on April 1, 2024 This layer was acquired/downloaded from the CalFire OSFM. Below is the original metadata that came with the layer:   The State Fire Marshal shall classify lands within state responsibility areas into fire hazard severity zones. Each zone shall embrace relatively homogeneous lands and shall be based on fuel loading, slope, fire weather, and other relevant factors present, including areas where winds have been identified by the department as a major cause of wildfire spread.  The California laws and regulations that require Fire Hazard Severity Zones include California Public Resource code 4201-4204 and California Code of Regulations Title 19, Section 2201.  Effective April 1, 2024 this regulatory adoption repeals Section 1280.1 of Title 14 California Code of Regulations and adopts similar regulatory provisions in Section 2201 of Title 19 California Code of Regulations.   A prior version of this file and data was released as part of the data package accompanying the final Public Comment period for Fire Hazard Severity Zones (September 29, 2023).  This previous version and this version are the same geographic representation of Fire Hazard Severity Zones and are now part of the formal regulation as adopted. While under normal workflow any revision to a public data file would get reflected in the filename, in this case the file name remains identical as it is part of the adopted regulation.  The only changes reflect edits to the metadata describing timing of adoption and effective date for the regulation.   Calistoga Revisions (2025) Revisions were made within Calistoga city limits by request of Calistoga City Fire (Jed Matcham). Fire Hazard Severity Zones were expanded to cover all parcels they intersect. Each parcel was assigned the highest severity zone it overlapped with.  Steps taken to update Fire Hazard Severity Zones within Calistoga Fire Hazard Severity Zones within Calistoga City Limits were erased from the original layer downloaded from Calfire.  Join Calistoga Parcels with original FHSZ layer by spatial intersect. If parcel intersects with multiple FHSZs, duplicate parcels with different FHSZ zones exist. Per parcel, only keep parcel with highest severity Dissolve parcel polygons from Calistoga_FHSZ by severity zone. This will combine features that have the same severity zone.  Clip ROW FHSZ Zones within Calistoga (They will be appended back in later). This is done so when I append them to the FHSZ_Erase layer, all polygons within Calistoga end at the city boundaries.   Append Calistoga_FHSZ_Dissolve polygon layer and Calistoga_ROW_Clipped to FHSZ_Erased layer. Merge ROW polygons of the same Fire Hazard Severity Class with Parcel Polygons of the same Fire Hazard Severity Class where they are adjacent.  Cleaned up the SRA / LRA divide to follow the Calistoga City Limits in North central Part of town
