Don't Spark a Wildfire!

The County's crackdown on illegal fireworks comes as the region is recovering from a series of devastating wildfires. 

Remember: Fireworks spark wildfires.


The CZU Lightning Complex series of fires in August 2020 charred thousands of acres, highlighting the region's threat from wildfire.
