When it comes to navigating through the storm (and all of the damage caused to local infrastructure), our team is here to guide you through the process. From ER and FEMA funding to picking up the pieces and fixing damaged roadways and bridges quickly, we have worked with multiple local agencies on emergency projects.
Roadway and highway slipout repairs
Bridge and retaining wall failures
We understand how crucial it is to get damaged roads and bridges fixed quickly and correctly so impacts to your communities are minimal and these types of damages don't occur again in the future.
MORGAN TERRITORY ROAD EMERGENCY SLIDE REPAIR
CONTRA COSTA COUNTY, CA
Extensive storms in 2016-2017 caused saturated soils that resulted in a large slide on a 200-foot segment of Morgan Territory Road. This slide closed the road and created severe hardship for the 1,000 cars a day that use the road to access their residences, businesses and agricultural land. Within 22 calendar days from the start of the project, Quincy developed the design, check, and 95% PS&E documents. The repair consisted of installing a tieback soldier pile wall on the uphill side of the road, installing a stitch pile wall on the downhill side of the road, and excavating and recompacting slide material under the roadway in between the walls.
TRONA WILDROSE WASHOUT
INYO COUNTY, CA
At upper Trona Wildrose Road, a gully wash resulting from a storm surge damaged the roadway and its side slopes. The purpose of this storm damage repair project is to provide a safe route for the public to access this area of Death Valley National Park. Quincy is working to restore the roadway to a usable condition and installing erosion control measures to prevent future storm damage.
GLEN CANYON ROAD SLIPOUT
SANTA CRUZ COUNTY, CA
Quincy provided design plans, specifications, and estimates for a soldier pile wall to repair a storm damage slipout on Glen Canyon Road. This included utility relocation and storm drainage upgrades.
ORO-QUINCY HIGHWAY STORM DAMAGE REPAIRS
BUTTE COUNTY, CA
Quincy is providing professional engineering and project delivery services to repair two damaged sites on the Oro-Quincy Highway from the 2017 storms. One site had a section of roadway fill fail as a slip out, affecting over 60 feet of roadway. At the second location, a MSE retaining wall failed causing a substantial drop in the roadway grade, settling 2-3 feet vertically and about 6 inches laterally.
Projects often have a large impact on the surrounding environment. That's why we love projects where we have the opportunity to improve and help habitats, from streambed restoration to fish restoration.
MENDOCINO COUNTY, CA
Quincy is providing professional engineering for a new road-stream crossing and roadway improvements to restore fish access to Manly Gulch in Mendocino Woodlands State Park. The stream will be rerouted to connect with the creek, as it currently crosses over a parking lot. Manly Gulch is considered a critical habitat for coho salmon and steelhead trout. This project will help improve fish access to upstream habitat, reduce flooding, and improve the overall habitat for salmonids.
SISKIYOU COUNTY, CA
In collaboration with the Salmon River Restoration Council, Siskiyou County and the US Forest Service, Quincy is working to realign and restore a portion of Hotelling Gulch Creek. It is critical to improve fish passage and access to upstream habitat, so as part of the stream restoration, an existing pipe culvert will be replaced by a larger bridge structure to remove a fish passage barrier at the intersection of the restored Hotelling Gulch and Cecilville Road.
GRIZZLY ISLAND ROAD
SOLANO COUNTY, CA
Quincy is providing engineering services for this habitat restoration project at the north boundary of the Grizzly Island Wildlife Area in Solano County. The project will raise Grizzly Island Road by approximately five feet to reduce flood risks and help restore marshland.
Our unique experience in procuring funding from various State and Federal sources (STIP, TEA-1, HBP, FHWA Special Grants) has allowed many of our clients to continue the preliminary planning, design, and final construction phases of their projects.
