The new Santa Rosa Criminal Courthouse will use the following Conco services: concrete pumping, concrete reinforcement, concrete formwork, concrete finishing, shotcrete, and Confoam. The courthouse will be located on the Sonoma County Administration Campus on Ventura Avenue, north of downtown Santa Rosa, and on the cleared site where the Old Jail facility stood. 

The courthouse will be 6 stories above ground and include a basement level. The lower 2 levels will contain courtrooms, general parking, and secured parking, with the upper 4 levels containing additional courtrooms and court administration offices. There will be 430 parking stalls available for daily operations within the courthouse, along with an additional 20 stalls for secured parking.

The new courthouse will contain 15 courtrooms and provide criminal, traffic, and juvenile dependency proceedings for the county. With an expanded size, the courthouse will include new features, such as larger jury rooms, in-custody holding, attorney interview and witness waiting rooms, a children’s waiting room, and a security entrance for screening court visitors.

Conco is expecting to place 11,000 cubic yards total of concrete and shotcrete, and 1,900,000 pounds of reinforcing bar. Rudolph & Sletten are overseeing the complete building process, partnering with Richard Meier & Partners Architects, Englekirk Institutional engineers, and Conco commercial concrete services.

Construction of the new courthouse began in June 2021, with anticipated completion in July 2023. It will total approximately 169,147 Building Gross SF (BGSF). Conco is excited to add a courthouse to our portfolio of projects in Western California, which will provide ongoing savings by consolidating court services.
