Sonoma County Pile Burning Regulations and Guidance in the Rainy Season

By Jacob McDaniel, January 2021

Before You Burn

Now that fire season is over and the rains have returned, regulations around pile burning have opened up throughout Sonoma County. Pile burning can be an effective method of reducing fuels around your home and promoting healthier forests, but it is important to burn safely and in compliance with pertinent regulations. Before burning, check that it is a permissive burn day, as well as that day’s weather forecast — Never burn in windy conditions or during unfavorable weather. Make sure to prepare the burn site, clearing the zone around the pile of vegetation to allow for a 10 foot clearance of bare dirt around the pile. Watch for overhead hazards like power lines and tree branches. Build your pile of dry vegetative material only. Dense piles with heavy material on top should result in good consumption of fuels. Piles should be no more than 4 feet wide and 4 feet tall, keeping in mind that more material can always be added as the pile burns down. Keeping piles manageable will help them burn down to hot coals by the end of the day, resulting in lighter smoke impacts to the surrounding community. This is because burning during times of the day with less relative humidity will result in a hotter, less smokey burn. Air quality issues from burn piles can often arise at night when an inversion occurs and fog settles in since smoke and heat are trapped closer to the ground and particulates can’t dissipate into the atmosphere. While burning, an adult should always be present and water and a shovel should be readily available at all times.  

Pile burning after the end of fire season generally does not require additional permitting or inspections from Cal Fire beyond an annual burn permit, which is free and remains valid for the calendar year. You can obtain one of these permits by watching a short safety video and entering your information on the Cal Fire burn permit website. In addition to this permit, you must coordinate with your regional air quality district in order to burn. These eased regulations are only in place until about May 1st when fire season returns. Sonoma County is regulated by two air quality districts, Northern Sonoma County Air Pollution Control District, and the Bay Area Air Quality Management District. To determine which district you should coordinate with and purchase your burn permit from, consult this map
