Title: NPS Facilities (Wildfire Risk)
Author: NPS Wildland Fire Program
Comments: The Wildland Fire Risk Assessment project was developed by the National Park Service's Fire and Aviation Management program as a response to the devastating 2011 wildfire season. This project developed a consistent assessment method that has been applied to NPS units nationwide regardless of variations in climate, fuels, and topography.
The assessment, based on Firewise® assessment forms, evaluates access, surrounding environment, construction design and materials, and resources available to protect facilities from wildland fire. Fuels treatment needs are evaluated using Firewise® recommendations for creating defensible space. Tactical recommendations are identified using a format similar to the Interagency Wildland Module Structure Assessment form.
The data collected during the assessment process can be used for:
• Identifying, planning, prioritizing and tracking fuels treatments at unit, regional and national levels, and
• Developing incident response plans for facilities and communities within NPS units.
The original spatial data for the assessments comes from a variety of sources including FMSS, WFDSS, NPMap Edits, manually digitized points using Esri basemaps as a reference at various scales, and GPS collection using a multitude of consumer and professional grade GPS devices. The facilities that have been assessed and assigned a facility risk rating have been ground-truthed and field verified. (In some rare occasions, facilities have been verified during remote assessments. Those that have been remotely assessed are marked as such). The resulting data is stored in a centralized geodatabase, and this publicly available feature layer allows the user to view that data.
The NPS Facilities feature layer includes the following layers and related tables:
• Facility - A facility is defined by the NPS as an asset that the NPS desires to track and manage as a distinct identifiable entity. In the case of wildland fire risk assessments, a facility is most often a structure but in special instances, a park unit may wish to identify and assess other at risk features such as a historic wooden bridge or an interpretive display. The facilities are assessed based on access, the surrounding environment, construction design, and protection resources and limitations, resulting in a numerical score and risk adjective rating for each facility. These ratings designate the likelihood of ignition during a wildland fire. The facilities are symbolized by their respective risk rating.
• Community - A community is a group of five or more facilities, a majority of which are within 600 feet of each other, that share common access and protection attributes. The community concept was developed to facilitate data collection and entry in areas with multiple facilities and where it made sense to apply treatments and tactics at a scale larger than individual facilities. Most of the community polygons are created using models in ArcMap, but some may have been created or edited in the field using a Trimble GPS unit. The communities are assessed based on access to the community, the surrounding environment, construction design of the majority of facilities within the community, and protection resources and limitations. The result of the assessment are two separate numerical scores: “Access and Protection Score” and “Community Score”. The Access and Protection Score is used to calculate each individual facility’s risk rating while the Community Score is the overall numerical score and associated risk adjective for the community as a whole. The communities are symbolized using a blue outline.
• Facility Tactics – The Facility Tactics table provides recommended tactics that can be implemented to protect the facility and/or community during a wildfire incident. These recommendations include estimated man hours necessary to complete the given tactic. This table is related to both the Facility and Community layers.
• Facility Treatment – The Facility Treatment table provides recommended treatments that should be implemented in order to create defensible space around the facility or community. The treatment recommendations are broken up by zone (Zone 1 – 0 to 30 ft radius, Zone 2 – 30 to 100 ft radius, and Zone 3 – 100 to 200 ft radius). The recommendations include reoccurrence periods for the treatments as well as estimated man hours necessary to complete the given treatments. This table is related to both the Facility and Community layers.
*The NPS Facilities layer is updated continually as new wildfire risk assessments are conducted and the Wildland Fire Risk Assessment project progresses. The assessment data contained here is the most current data available.
