Full Breakdown

005). 010 draws the no-drinking zone along four specific stretches: the entire length of Wharf Road from its intersection with Brighton Avenue to its terminus at the beach near the mouth of Bolinas Lagoon; the entire length of Brighton Avenue from Wharf Road to its terminus at Bolinas Beach; Park Avenue where it runs past the County Park; and the County Park itself plus adjacent areas bordered by Park and Brighton Avenues. 020 ties enforcement to state law: anyone found with a can, bottle, or other container of alcohol that has been partially opened inside those boundaries is guilty of an infraction under Business and Professions Code § 25620, Marin's local open-container hook.

030 lets the Board of Supervisors suspend the whole chapter for specific periods to accommodate town celebrations and carnivals in Bolinas, so the rule is not absolute year-round. 11, imposes its own alcohol restrictions during the Marin County Fair carnival area and is enforced independently of this Bolinas-specific rule. The Marin County Sheriff's Office, which patrols unincorporated Bolinas, is the enforcing agency for open-container infractions in this zone.

Violations & Fines

Possessing an opened alcohol container within the mapped Bolinas zone is charged as an infraction under § 6.10.020, tied to Business and Professions Code § 25620; infractions carry a fine set by the county's infraction schedule rather than jail time. The Sheriff's Office issues the citation on the spot; Chapter 6.10 carries no misdemeanor upgrade in its own text, unlike many other nuisance chapters in the code.

Frequently Asked Questions

Where exactly is public drinking banned in Bolinas?
Marin County Code § 6.10.010 bans it along the full length of Wharf Road (from Brighton Avenue to the beach at Bolinas Lagoon), the full length of Brighton Avenue (from Wharf Road to Bolinas Beach), the stretch of Park Avenue that runs past the County Park, and the County Park and adjoining areas bordered by Park and Brighton Avenues. Outside these mapped blocks, the chapter does not apply.
What happens if I'm caught with an open container there?
Under § 6.10.020, having any can, bottle, or other receptacle with alcohol that has been partially removed inside the mapped zone is an infraction, citing Business and Professions Code § 25620. Deputies from the Marin County Sheriff's Office can issue the citation without further proof of intoxicated behavior.
Can the county ever lift the ban temporarily?
Yes. Section 6.10.030 lets the Board of Supervisors suspend Chapter 6.10 for periods covering town celebrations, carnivals, and similar community events in Bolinas, so drinking in the mapped area can be briefly authorized for those occasions.
Does this rule apply anywhere else in Marin County?
No. Chapter 6.10 is written specifically for "the unincorporated community Bolinas" and does not extend countywide. A separate rule, Chapter 6.11, covers alcohol consumption at the Marin County Fair carnival area under its own preamble and penalty section.
