Contact your local Fire Agency or Air Quality for more information.


Residents are reminded that BURNING when allowed, MUST COMPLY WITH MENDOCINO COUNTY AIR QUALITY BURN REGULATIONS.

Burn responsibly and do not cause a smoke nuisance for your neighbors. Manage burns to reduce excessive smoke by keeping material dry and burning hot with visible flames. Never allow your burn piles to smolder overnight. Avoid burning when high pressure is forming and a visible inversion is evident.

Cooler temperatures and rainfall alone do not prevent fires from escaping control. Landowners are responsible for safely burning outdoors and maintaining control at all times. For tips on safe burning visit the CAL FIRE website at www.fire.ca.gov or check with your local fire agency.
