Contra Costa County Public Works
Park Engineering’s personnel provided construction management and inspection for County public works projects through an on-call Construction Management and Inspection contract. The team worked on several federally funded public works as well as privately funded developer projects, such as new subdivision construction and the expansion of local roadways and arterial improvements. Projects include:
- Pinehurst Road Sinkhole & Culvert Repair Project – this $450,000 federally funded project replaced approximately 50-feet of existing 84-inch RCP under Pinehurst Road. This replacement work required an extended full roadway closure with significant coordination and outreach to neighboring communities. Additional work included the construction of culvert baffles in the existing CMP for improved wildlife habitat.
- Kirker Pass Road Northbound Truck Climbing Lane Project – The federally funded project constructed of a truck climbing lane in the northbound direction. The project is approximately 1 mile in length, beginning at the Concord Pavilion and ending at the northern Hess Road intersection. Road widening required multiple retaining walls due to the existing slopes and drainage adjacent to the roadway. The project also included pavement rehabilitation on the north and south bound lanes between the City of Concord / County limits to approximately 4,200 feet north of North Hess Road for a total of about 1.6 miles. The total project length is about 2 miles. The project was funded by Federal grants, State SB1 funds, and local County funds.

Work involved installation of sheetpile walls, levee fill, concrete walls, and HMA pavement to raise levee roads. The project required close environmental monitoring and coordination with various entities including East Bay Regional Park District and County Flood Control District. The project was funded by local County funds and State funds.
