Thomas Fire
The Thomas Fire burned over 281,000 acres in December 2017, mostly in Ventura County, and quickly became the largest recorded fire in California history. Burning through forests, grasslands, orchards, and housing tracts, the fire’s path eventually impacted the area from Fillmore to Santa Barbara, and from Ventura north, through Matilija Canyon, Ojai, and beyond destroying over 1,000 structures.
Fires such as this have many impacts on both the community and our resources, including hazards from ash and toxins, and an increased risk of flooding and landslides. Here are some answers to FAQs about post-fire Water Quality Concerns and Erosion and Sediment Control. The County of Ventura launched a website dedicated to helping victims of the Thomas Fire find information to help their recovery, including debris removal, rebuilding, permits, hazardous materials, health issues, how to get rain ready, and much more. Please visit www.VenturaCountyRecovers.org for more information.
