The wildland-urban interface and statewide wildfire risk map was made available through the Oregon Explorer online tool June 30.
The map is a tool to help inform decision making and planning related to mitigating wildfire risk for communities throughout Oregon. Inclusion in the interface zone can affect requirements of property owners and building code.
Oregon State University produced the map based on administrative rules adopted by the Board of Forestry at their June 8 meeting. The rules — developed in consultation with a rulemaking advisory committee comprised of 26 members representing a wide variety of stakeholder interests — outline:
• Boundary criteria for the wildland-urban interface;
• How each of five wildfire risk classes are assigned to individual properties;
• How property owners in the extreme and high-risk classes are to be notified;
• How property owners may appeal their assigned risk class.
Out of a total number of 1.8 million tax lots in Oregon, the map identifies:
• 4.4 percent of Oregon’s land area is in the wildland-urban interface.
• 8 percent of total tax lots in Oregon are in the wildland-urban interface and in high or extreme risk classifications, which is 120,276 tax lots.
• Approximately 80,000 of the 120,276 tax lots in the wildland-urban interface and high or extreme risk classifications currently have a structure that may be subject to new codes or standards, which is about 5 percent of tax lots.
Property owners in the high and extreme risk classes will receive written notice from ODF indicating the property’s risk class and whether it’s in the wildland-urban interface. The notice will inform them if they may be subject to future defensible space or building code requirements and how to find information on those requirements. It will also provide information on the process to appeal a property’s risk classification.
While property owners in the high and extreme risk classes will receive letters about their property, anyone can use the online risk map at oregonexplorer.info to get information on where they live.
ODF will soon announce information sessions to address questions about the map’s function and purpose and help Oregonians understand the process to appeal their risk class.
For properties in the wildland-urban interface and a risk classification of high or extreme, Senate Bill 762 requires actions to help mitigate the risk of wildfire through adoption of defensible space and home hardening building codes.
The Oregon State Fire Marshal is passing defensible space code requirements through a public process.
Code adoption of defensible space requirements will occur in December 2022, after the map validation and appeals period is closed. Those requirements won’t apply until later. The Building Codes Division will adopt home hardening building codes through a public process. Building codes will be adopted Oct. 1 and will be effective April 1, 2023.
