Town reviews wildfire-interface map and House Bill 48 implications

Charleston — Representatives from Wasatch County Fire presented an updated wildland-urban interface map at the March 5 town council meeting and discussed how that map could shape local wildfire mitigation requirements and insurance outcomes.

Troy Morgan and Cling Neerings (Wasatch County Fire) showed areas with higher structure exposure and discussed two possible boundary options — extending the interface through Daniels Creek or stopping at Highway 189. They noted the town’s currently adopted code dates to 2006 and that a 2024 model code under consideration would change sprinkling requirements and how parcels are designated.

Morgan explained draft language in House Bill 48, describing a temporary flat fee for properties deemed high-risk until 2028 and a later transition to a per-square-foot assessment. Presenters said the mapping is dynamic and would change as development occurs; they estimated the current map would affect about 4,500 homes regionally and said none on the current map are inside Charleston town limits.

Presenters and staff also discussed how the designation could affect homeowner insurance — including the potential for insurers to alter coverage or rates — and advised residents they can contest insurer decisions when properties fall outside high-risk zones. The presenters recommended stricter fireworks boundaries than the wildfire map, especially south of Highway 189, because of fire-spread risk in dry conditions.

Planner Brian Preece recommended placing map-adoption on next month’s agenda but noted that legislative changes could arrive within 24 hours and affect the town’s approach. The council did not adopt the map at the March 5 meeting and indicated it will revisit the matter when the consultants and additional legal context are available.
