Common causes of serious injuries in Contra Costa County
Contra Costa combines busy commuter freeways, a tunnel through the hills to Alameda County, heavy industry along the water and suburbs spreading east. That mix produces freeway crashes, industrial accidents and transit injuries.
- State Route 4 and I-680. SR-4 links Antioch, Pittsburg, Oakley and Brentwood with central county and has a major interchange with I-680. Read about car accident claims and, for big rigs on these routes, truck accident claims.
- SR-24 and the Caldecott Tunnel. Caltrans is rehabilitating the tunnel bores between Contra Costa and Alameda counties, including ventilation and safety upgrades. Work zones and tunnel merges call for extra care.
- Refineries and industrial plants. Contra Costa Health enforces an Industrial Safety Ordinance at facilities including the Phillips 66 Rodeo refinery and the Martinez Refining Company, and Richmond's ordinance covers the Chevron Richmond Refinery. See workplace injuries for how third-party claims work alongside workers' comp.
- Transit and walking. BART, AC Transit, County Connection, Tri Delta Transit and WestCAT all run here. Riders hurt boarding, or struck walking to a station, should see bicycle and pedestrian accidents.
Common injuries after accidents in Contra Costa County
Freeway and tunnel crashes here tend to cause neck, back and head injuries. Refinery and plant accidents can mean burns, crush injuries and falls from height.
- Neck and back injuries. Rear-end crashes in SR-4 and I-680 commute traffic, and merges near the Caldecott Tunnel, often cause whiplash and disc injuries that can take weeks to show their full effect. See neck injuries and back injuries.
- Burns, crush and fall injuries at industrial sites. Work at refineries and plants along the water can involve heat, heavy equipment and elevated platforms. Serious falls can damage the spine; see spinal cord injuries.
- Fractures and head injuries for riders and walkers. A fall while boarding BART or a bus, or being struck walking to a station, can break bones or cause a concussion. When a crash is fatal, the family may have a wrongful death claim.
Getting your crash report
The CHP Contra Costa Area office at 5001 Blum Street, Martinez, handles most freeway crashes. The Contra Costa County Office of the Sheriff patrols unincorporated areas and the contract towns of Danville, Lafayette and Orinda. Cities such as Richmond, Concord and Antioch have their own police departments.
Filing deadlines for Contra Costa County injury claims
Most injury suits must be filed within two years CCP 335.1. If a public entity is involved, you generally have six months to present a written claim first Gov. Code 911.2. That covers the County of Contra Costa, cities like Concord and Richmond, BART and Caltrans.
The County takes claims through the Clerk of the Board of Supervisors, 1025 Escobar Street, Martinez. County Connection, Tri Delta Transit and WestCAT are each run by a separate transit authority, and school districts are public entities too. After a written denial, the lawsuit deadline is generally six months Gov. Code 945.6, and a child's age does not extend the claim deadline CCP 352. Enter your date in the Claim Clock.

Questions
Contra Costa County personal injury FAQ
What should I do after a rear-end crash on Highway 4?
Move to safety if you can, call 911 and get checked the same day, because neck and back injuries from a rear-end impact often worsen over the next few days. On the freeway the CHP Contra Costa Area usually responds, so ask for the report number. Photograph the vehicles, keep every medical bill and avoid recorded statements to the other driver's insurer.
How do I file a claim against Contra Costa County?
The County takes injury and property claims through the Clerk of the Board of Supervisors at 1025 Escobar Street in Martinez. The claim is generally due within six months of the injury (Government Code section 911.2). Cities, BART and the bus agencies are separate public entities, so each one needs its own claim.
Who handles a crash report on SR-4 or I-680?
Freeway crashes in the county are usually investigated by the CHP Contra Costa Area office at 5001 Blum Street in Martinez. Crashes on city streets go to that city's police department, and the Office of the Sheriff covers unincorporated areas and its contract towns. Request the report from the agency named on the card the officer gave you.
I was hurt at a refinery or plant job in Contra Costa County. Do I have a case?
Workers' compensation usually covers an employee's injury on the job. If a contractor, equipment maker or property owner other than your employer caused the harm, you may also have a separate injury claim against them. We look at who controlled the site and the equipment before giving you an answer.
