Overview<\/SPAN><\/P>

Senate Bill 762 (SB 762), enacted in 2021, was an omnibus bill which advanced a suite of wildfire programs collectively aimed at helping Oregon\u2019s communities and landscapes adapt to a changing fire environment. Under SB762, OSU was responsible for developing three specific data products that would help state agencies develop and implement those wildfire programs in a strategic manner. Senate Bill 762 was amended by Senate Bill 80 in 2023, but OSU is still responsible for three maps to support state agencies:<\/SPAN><\/SPAN><\/P>

  1. A comprehensive statewide map of wildfire hazard<\/SPAN><\/SPAN> (\u201cstatewide hazard map\u201d). Senate Bill 80, Section 1. The map will represent hazard at all locations in Oregon by integrating estimates of annual wildfire likelihood and wildfire intensity, and summarizing the results with each tax lot in the state. Each tax lot will be classified as either \u201clow,\u201d \u201cmoderate,\u201d or \u201chigh\u201d hazard. The statewide hazard map represents the environmental hazard based on climate, weather, topography and vegetation. <\/SPAN><\/SPAN><\/P><\/LI>

  2. A statewide map of the wildland-urban interface<\/SPAN><\/SPAN> (\u201cWUI\u201d). Senate Bill 762, Section 7 (7)(c); and Senate Bill 80, Section 2. The WUI is defined by two general criteria: the density of structures, and the proximity and amount of flammable vegetation. The WUI map represents locations in Oregon where there are enough structures and sufficient flammable vegetation to support a potential future wildfire disaster. <\/SPAN><\/SPAN><\/P><\/LI>

  3. A map of locations of socially and economically vulnerable communities.<\/SPAN><\/SPAN> Senate Bill 762, Section 7(7)(d). The map of social vulnerability in Oregon uses 15 indicators collected from the 2020 American Community Survey data summarized at the Census Block Scale. Social vulnerability of each Census block group is represented relative to all other Census block groups. State agencies are not required to use the social vulnerability map and data pertaining to that map are not included in this geodatabase. More information about social vulnerability can be found at: https://ir.library.oregonstate.edu/concern/datasets/z890s265n. <\/SPAN><\/P><\/LI><\/OL>

    The statewide hazard map and the WUI map are intended to be used in conjunction with one another by the Oregon State Fire Marshal and the Department of Consumer and Business Services, Building Codes Division during implementation of specific wildfire programs. Namely:<\/SPAN><\/SPAN><\/P>
