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.
  • Buchanan Airfield Runway Rehabilitation Project – The work consists of rehabilitating asphalt concrete pavement, full width, on Runway 14L-32R, with the exception of the Runway 1L-19R intersection. Work included cold milling, crack repair, full depth asphalt and PCC pavement removal, earthwork/ grading, asphalt surface course, runway grooving, application of new pavement markings, runway & taxiway lighting improvements and signage modifications.
  • San Pablo and Wildcat Creeks Levee Remediation FEMA mandated levee remediation to raise freeboard to 100 year flood requirements.  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.
  • Giaramita Street Rehabilitation Sidewalk replacement and roadway rehabilitation work consisted of sidewalk improvements, curb ramps, curb, gutter, valley gutter, pavement conform, storm drain improvements, slurry seal, signing, and thermoplastic striping. The project was funded by local County funds and federal Block Grant Funds.
  • 2015 Asphalt Rubber Cape Seal; 0672-6U2149. The work consisted of applying an asphalt rubber chip seal covered with a type II slurry seal to approximately 259,020 square yards of roadway located at East Richmond Heights area of west Contra Costa County and Shadow Creek area of Blackhawk in the East Contra Costa.  Work also included installation of 40 survey monuments, surface preparation, striping removal, and placement of thermoplastic striping and pavement markings.
