BOONVILLE – Caltrans District 1 and the County of Mendocino announced a Clean California (Clean CA) Dump Day event for Saturday, Aug. 19, at the Mendocino County Fairgrounds.

This Dump Day allows residents to drop off mattresses and off-rim car and light truck tires (limit nine per load) for free. Dump Day events were made possible through Governor Gavin Newsom’s Clean California initiative. A sweeping $1.2 billion, multiyear cleanup effort led by Caltrans to keep roads and waterways free of litter, create thousands of jobs, and transform state and local public spaces through beautification efforts.

Who: Boonville-area residents

What: Free Dump Day event

When: Saturday, Aug. 19, 10 a.m. - 2 p.m. or until capacity reached.

Where: Mendocino County Fairgrounds 14400 Hwy 128, Boonville

Tires on rims cannot be accepted.

Caltrans reminds motorists to properly secure and tarp all cargo loads prior to driving. Transporting unsecured loads is unsafe, illegal, and pollutes California's roads and waterways. Loads that are not tied down, enclosed, or secured by tarps or other means will not be accepted.

Tips for securing your load:

  • Completely cover loads with tarps or cargo nets. Debris can escape from gaps.
  • Remove loose material and trash before driving.
  • Don't overload – keep materials level with your truck bed.
  • Put light items lower, tie large items to the vehicle for traffic safety.
  • For questions about this Dump Day event, please contact or call (707) 572-7266.

About the Campaign:

Clean California Community Dump Day events are made possible through Governor Gavin Newsom's Clean California initiative, a sweeping $1.2 billion, multiyear clean-up effort led by Caltrans to remove trash, create thousands of jobs, and engage communities to transform public spaces. Since 2021, the program has removed 1.4 million cubic yards of trash, created 3,500 jobs, and awarded $300 million in local grants. Visit to learn more about how Clean California is transforming communities and educating the public.

In February, Gov. Newsom announced a new funding round for $100 million in grants for local Clean California projects. There are also a variety of career and job opportunities through Clean California. For more information on this, please visit the jobs section at

Caltrans is also developing the Clean California Community program, in which communities from across the state can earn a designation by meeting criteria centered around preventing and cleaning up litter, promoting recycling, and otherwise greening or beautifying their communities. Incentives will also be offered to encourage communities to earn this designation.
