Summary

Dumping refuse on public property, rights-of-way, watercourses, or someone else's land anywhere in unincorporated Mendocino County is unlawful under Section 9A.08.030, and the county can order a private property owner to remove illegally accumulated refuse under Section 9A.24.050 if it threatens public health.

These county ordinances apply to unincorporated areas of Mendocino County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

No person shall throw or deposit or cause to be thrown or deposited, any refuse or abandon any material whatsoever, in or upon any public property, public right-of-way, watercourse, or banks of any watercourse, or upon the premises of any other person except at a disposal site, container site, materials recovery facility (MRF), transfer station, recycling industry or authorized recycling entity approved by or acceptable to the County or as provided in this and other County ordinances.

Full Breakdown

030 makes it unlawful to throw, deposit, or abandon any refuse on public property, a public right-of-way, a watercourse or its banks, or on someone else's premises, except at an approved disposal site, container site, materials recovery facility, transfer station, recycling industry, or authorized recycling entity. 020, applies the same rule to a person's own property: no owner or occupant may throw, drop, dump, bury, or burn refuse on their own premises outside an approved disposal channel, though wood may be stacked for household or agricultural use and composting is allowed if done in a healthful manner.

050 authorizes the county to require the property owner to remove and properly dispose of it, using any provision of the county code or state law necessary to enforce that order. 030's process: the Director of the Department of Transportation or a designee must first give reasonable notice and a chance to correct, often via a cart tag or posting on the property, before issuing a citation for an uncorrected violation. 020 extends to collection containers, vehicle loads, and disposal facilities to confirm compliance.

Violations & Fines

Section 9A.24.030(H) makes any Title 9A violation, including illegal dumping, an infraction unless state law makes it a misdemeanor or felony, and the county can additionally pursue a public nuisance declaration and abatement, injunctive relief, and recovery of its full enforcement costs from the violator. The county may also pursue unpaid administrative citations through the California courts.
