| Reason for Recommended Action/Background |
This amendment will allow MGE Engineering to provide engineering support during construction of the County Road (CR) 40 Bridge Over Cache Creek Replacement Project.
BACKGROUND
The CR 40 Bridge over Cache Creek (aka Low Water Bridge) is in northwestern Yolo County, near the intersection of County Road 40 and State Route 16, approximately 5 miles northwest of the town of Rumsey. The bridge is within the Cache Creek Regional Park’s Lower Site. The existing six-cell reinforced concrete box culvert bridge was determined to be structurally deficient with a safe load capacity designated at zero tons and was closed to vehicular traffic in 2008.
When a portion of the Rumsey area burned in the 2015 Rocky Fire, the State of California Department of Forestry and Fire Protection (Cal Fire) could not use the current CR 40 bridge for its heavy equipment to access fire lines and instead had to build a temporary crossing over Cache Creek. Most recently in the 2020 LNU Complex Fire, the National Guard was mobilized to install a temporary bridge just upstream of the failed low water crossing, so Cal Fire could fight the wildfire in the wilderness area west of Cache Creek.
In order to accelerate replacement of the bridge, the County received a grant from Cal Fire in 2018 to fund the preliminary engineering and environmental phases of the project. MGE Engineering was retained by the County on August 10, 2018 and has since completed the design phase work under Yolo County Agreement No. 2018-119.
The bid opening for the CR 40 Bridge Over Cache Creek Replacement Project occurred on June 11, 2021, and staff is moving forward to secure a contractor to complete bridge construction. Since Agreement No. 2018-119 only included preliminary engineering and environmental activities, an agreement amendment is needed to allow the bridge designer, MGE Engineering, to assist the County through completion of the project. Amendment 1 will revise the scope, term, and increase the contract amount by $76,187.44 to do so. |
