As residents and visitors to Lone Tree prepare to celebrate Independence Day, the City of Lone Tree would like to remind everyone that only permissible fireworks, as defined by Colorado state law, are allowed within the City limits.
“Permissible fireworks” means small firework devices designed to produce an audible or visual effect by combustion but do not leave the ground. These fireworks are commonly called “consumer fireworks” and generally include cylindrical fountains, cone fountains, wheels, ground spinners, illuminating torches, dipped sticks and sparklers.
Fireworks that are aerial, explode, or fragment – such as bottle rockets, mortars, roman candles, firecrackers, cherry bombs and similar more powerful fireworks – are illegal in the state of Colorado and the City of Lone Tree. The illegal use of fireworks in the City of Lone Tree may result in a fine of up to $2,650 or up to 1 year imprisonment, or both.
We encourage visitors and residents to let the professionals handle the major fireworks and visit a local show like Lone Tree’s Independence Day Celebration. For more information on fire safety and Wildfire mitigation, visit our page.
