Park City residents and visitors will have to leave Fourth of July fireworks to the professionals.

The mountain town has declared a ban on open flames and fireworks, effective Thursday night, said Mike McComb, who oversees emergency management for Park City.

The ban doesn’t cover the professional shows at Park City Mountain Resort — July 3 in the Canyons section of the resort and July 4 at the main ski runs.

But that could change if conditions worsen, McComb said.

The ban on private fireworks has been put in place five of the past six years, McComb said. Residents used to complain, he said, but “folks are largely accustomed to it now. People are becoming more aware of the impacts of a fire.”

McComb cited this winter’s lower-than-normal snowpack for creating conditions that raise the odds for wildfires. “Normally, the snows compact the grasses,” McComb said. “When the snow melts early, those grasses tend to stand up, and with the heat and the wind, they just dry out more quickly.”

A new law this year gives Utah municipalities more leeway in banning fireworks over fire hazards. The law also cuts back on the number of days fireworks can be discharged over the July 4 and July 24 holidays, from 14 to eight days. Where they are permitted at all, fireworks may be used from July 2 to July 5, and from July 22 to July 25.

In Salt Lake City, fireworks and open flames are banned east of 900 East (including the University of Utah campus, north of South Temple, in City Creek Canyon, west of Redwood Road, and in all city parks and wildland urban interface areas). The ban includes such neighborhoods as Rose Park, Glendale, the Avenues, Federal Heights, Harvard/Yale and Sugar House.
