Which Agency Holds a Report from Walnut Creek
The report of an incident is released by the agency that took it; the court and the jail hold their own records of the same event, but not the report.
Inside Walnut Creek that is the agency that reports to the FBI for the city (filed by the FBI as Walnut Creek Police Department); outside it, the Contra Costa County Sheriff's Office.
The FBI's list also places the Highway Patrol's Contra Costa Area Office in Contra Costa County; a report taken on a state highway by it comes from that agency's own records office.
The FBI's list also carries San Francisco Bay Area Rapid Transit in Contra Costa County and Union Pacific Railroad in Contra Costa County (other agency) and Contra Costa Community College (campus police), each with a records office of its own.

What the California Public Records Act Requires
Under the California Public Records Act the agency must answer a request within 10 days, with up to 14 more days in unusual circumstances, and it may charge the direct cost of copying only, not staff time. The request goes to the agency that holds the report, in writing, and does not have to say why the report is wanted.
Any other county record goes through the county records request page SearchSystems verified, at contracosta.ca.gov/8129/Public-Records-Requests (page title: Public Records Requests | Contra Costa County, CA Official Website).
A defendant who has been charged gets the report through the case: the District Attorney, (925) 957-8602, handles discovery for pending cases.
