Douglas County implemented Stage 1 fire restrictions Monday due to heightened wildfire danger, which includes a ban on personal fireworks ahead of the Independence Day holiday.

Under the restrictions, open burning of any kind, the use of personal fireworks and the use of model rockets are prohibited. Professional fireworks displays that comply with state law can continue.

The restrictions took effect immediately in unincorporated Douglas County, Castle Pines and the Larkspur and will remain in place until further notice, officials said.

County officials said the restrictions are intended to reduce the risk of wildfires and protect public safety during a period of elevated fire danger.

“We understand America’s 250th birthday is a special occasion to celebrate with loved ones in a major way, but with the current extremely severe fire danger we face, the safety and lives of our community is top of mind right now,” the Douglas County Sheriff’s Office said in a news release. “Our experts considered the risks: the lack of moisture we have, wind possibilities, and lack of state resources available as firefighters courageously work to suppress a number of fires in our state this week, when making the ultimate decision to implement stage one fire restrictions.”

Several activities remain permitted under the restrictions.

Small recreational fires are permitted only in fixed, permanent metal or steel fire pits located at developed picnic or campground sites. Temporary rock fire rings are not allowed.

Charcoal grills and portable patio fire pits that are used safely and under supervision are allowed.

Violations of the restrictions are punishable by fines of up to $1,000.

Officials urged residents and visitors to use caution and celebrate the holiday safely while the restrictions remain in place.
