One fire Tuesday night was a highly visible blaze along I-80 and 1300 East during the professional fireworks show at Sugarhouse Park.

COTTONWOOD HEIGHTS — Three homes narrowly escaped serious damage Tuesday night due to fast moving grass fire believed to have been started by fireworks.

The fire was one of dozens of grass fires throughout Salt Lake and Davis counties that started about 10 p.m. and capped off one of the busiest Fourth of July holidays for firefighters in recent memory.

"For a single day, (it was) extraordinary even for us on the Fourth of July," said Unified Fire Authority Battalion Chief Steve Prokopis.

The Cottonwood Heights grass fire started near Enchanted Hills Drive in a vacant field at 3500 East and 7400 South. It burned just 3 to 4 acres at first, but then there was a "huge shift" in the wind, Prokopis said.

"There was significant wind changes and down-canyon winds, and it blew from 3 acres to closer to 10 pretty quickly," he said.

The fire caused exterior damage to at least three homes. One home had a deck damaged by the fire, and at least two others had siding melt due to the heat. At least one outbuilding was lost, Prokopis said, and one homeowner was displaced.

"It burned on the outside of her home and it did end up breaking through one window, so she did end up getting quite a bit of smoke in the home," he said.

As that fire was burning, fire crews were responding to dozens of grass fires all over the valley.

"Right at the time all the fireworks were going off in every neighborhood and every professional show, it was just a really busy time," Prokopis said.

One of those fires was a highly visible blaze along I-80 and 1300 East during the professional fireworks show at Sugarhouse Park.

Crews in Davis County also responded to several fires Tuesday night.

Prokopis said Unified firefighters started the day with a fire in Taylorsville and then responded to or assisted other agencies in West Valley City, Riverton and Midvale throughout the day.

"It was just the perfect storm: high temperatures, low humidity and a wet spring, considerably taller fuels than previous years," he said.

No injuries from the fires were reported, police said.
