Preparedness Context

Maintaining at least 30 feet of lean, clean vegetation around structures in Granite County and keeping gutters clear of debris significantly reduces ignition risk from wind-driven embers. Alongside wildfire, earthquake at the 38th percentile nationally means a multi-season preparedness mindset — fire season and flood or storm season often require different household plans. Granite County's households benefit from reviewing homeowners insurance before fire season, specifically whether the policy covers replacement cost rather than actual cash value, and whether it includes additional living expenses if displacement is required.
