Martinez city parks are generally closed from 10:00 p.m. to 6:00 a.m. daily under Municipal Code Chapter 12.08, except for permitted events and lit sports facilities during active reservation. Being in a park after closing, camping overnight, and being in a park while it is posted closed are infractions. The Martinez Waterfront Park and Regional Shoreline (East Bay Regional Park District) have their own posted hours.
Martinez Parks and Recreation operates numerous parks and facilities, including Rankin Park, Hidden Lakes Park, John Sparacino Park, Susana Park, and the Martinez Waterfront Park. Under MMC Chapter 12.08, all city parks are closed to public use from 10:00 p.m. to 6:00 a.m. unless a valid permit authorizes after-hours use (e.g., reserved group picnics, lit ballfield leagues, or community events). Park hours are posted at main entries.
Prohibited activities in parks after closing include loitering, camping, overnight parking, sleeping in vehicles, and amplified sound. Overnight camping anywhere in a Martinez city park without permit is prohibited; people experiencing homelessness are directed to Contra Costa County shelters and the coordinated entry system (CORE outreach) in compliance with Martin v. Boise and Johnson v. Grants Pass 2024 frameworks, which the city has navigated with time-place-manner rules rather than blanket camping bans.
The Martinez Regional Shoreline, operated by East Bay Regional Park District (EBRPD), follows EBRPD park hours (generally 5:00 a.m. to 10:00 p.m., with seasonal adjustments). EBRPD police have independent enforcement jurisdiction at the Regional Shoreline under Ordinance 38.
Dogs must be leashed (6-foot maximum) in city parks under MMC Title 6, except in designated off-leash areas. Consumption of alcohol, glass containers, smoking, motorized vehicles off-road, and drone launches without permit are all prohibited by MMC 12.08 and park posted rules. Violations are infractions subject to citation under MMC 1.20, with fines starting at $100.
