Concord Trash & Recycling: Illegal Dumping Rules (2026)

Illegal dumping is a significant regional issue addressed through overlapping state and local authority. California Penal Code §374.3 makes it a misdemeanor to dump waste on public or private property without consent; first-offense fines range from $250 to $3,000, second offense $500 to $6,000, and third or subsequent offense $750 to $10,000, plus mandatory cleanup costs, community service, and potential vehicle impoundment if a vehicle was used. Commercial dumping carries enhanced penalties up to $10,000. Concord Municipal Code Title 6 parallels these state provisions, authorizing nuisance abatement and cost recovery liens against responsible parties. Common violations include furniture and mattress dumping at roadsides, construction debris in vacant lots, and contaminated material in storm-drain creeks (which triggers additional Clean Water Act and California Water Code §13304 liability). Property owners are responsible for removing dumped material on their property, but may pursue restitution from identified dumpers. Concord accepts reports through its "Fix-It Concord" web portal and mobile app; the city also conducts routine abatement of hotspots such as Monument Corridor and parts of the Iron Horse Trail. Concord Police operate occasional surveillance-camera programs at chronic dumping sites. Residents with legitimate bulky waste should use Republic Services' free annual bulk pickups or self-haul to Mt. Diablo Recycling.
