Staff briefs commission on state-mandated wildland-urban interface map and implications for building standards

Planning staff briefed the commission on a state-mapped wildland-urban interface (WUI) map and what it means for Midway residents and future construction.

Staff explained the WUI map categorizes areas by wildfire risk: lighter colors indicate lower risk, orange indicates moderate risk and red indicates high risk. "As you get into areas where there is more density, there's a greater chance of fire jumping from one structure to another," planning staff said, and pointed to higher-risk areas along Lime Canyon and older cabin subdivisions such as Oak Haven.

The state-directed process requires cities and counties to adopt local maps and, ultimately, set building and landscaping standards that vary by risk category. Planning staff told commissioners that properties in higher-risk areas will be subject to more wildfire-resistant building codes and landscaping rules. "Basically, if you're in a high risk area, you end up paying more than those in a low risk area," staff said, explaining the state envisions a property-based fee to fund prevention and firefighting over time.

Staff emphasized the locally adopted line follows identifiable landmarks (roads, creeks) for clarity and noted the adopted map could be revised in the future, perhaps in about a year, as development patterns change. The presentation was informational; no regulatory action was taken by the commission at the meeting.
