Firefighters say about 30 homes in Utah have been evacuated after a small wildfire ignited near a neighborhood backing up to a mountainside.

Dave Ulibarri with Salt Lake County's Unified Fire Authority said the blaze started early Wednesday on a mountainside above the city of Draper and spread quickly through dry grass and brush.

Fed by high winds in the steep area, the fire came within 60 to 80 feet of houses overnight. Authorities say some fences were damaged, but no homes have been lost.

Evacuation orders remain in place as crews fight the blaze in temperatures that could reach the low 90s. The fire is about 5 percent contained.

By Wednesday morning, authorities say crews had gained some containment of the fire.

The danger is concentrated around high-voltage Pacific Gas & Electric poles along the highway. No one has been injured.
