DISCUSSION:
On Mar. 7, 2017, the Governor of the State of California declared a disaster for Humboldt County due to severe winter storms, flooding, and mudslides. Mattole Road (F3D010) Post Miles 4.40, 5.10, 9.00, and 11.05-11.29, located in the Honeydew area of southern Humboldt County, experienced roadway, embankment and culvert failures. Temporary emergency repairs were performed at the time of the disaster to maintain essential traffic.
On Sept. 13, Sept. 19, and Nov. 4, 2019, the Humboldt County Department of Public Works (Public Works) received funding approval from the Federal Highway Administration to proceed with the Mattole Road (F3D010) Post Miles 4.40, 5.10, 9.00, and 11.05-11.29 Storm Damage Repair Project. Public Works prepared plans and specifications for work consisting of constructing a welded wire wall, replacing and upsizing a culvert, and installing geosynthetic reinforcement, rock slope protection, guard rails, and sediment and erosion control items measures.
On Apr. 28, 2020, the Board of Supervisors authorized the Clerk of the Board to advertise the Mattole Road (F3D010) Post Miles 4.40, 5.10, 9.00, and 11.05-11.29 Storm Damage Repair Project for bids. On May 26, 2020, the county received five (5) bids for the project. The contracts were awarded to William J. Etter Construction, the lowest responsible bidder, on Jun. 23, 2020. The award amount was Four Hundred Twenty-Six Thousand Nine Hundred Eighteen Dollars and Seventy-Nine Cents ($426,918.79), and contract change orders executed during the project increased the authorized amounts as follows: $46,087.08 for Contract Number 217441 (Post Mile 4.40), $22,614.16 for Contract Number 217426 (Post Mile 5.10), $36,901.14 for Contract Number 217428 (Post Mile 9.00), and $15,316.02 for Contract Number 217272 (Post Mile 11.05-11.29).
Public Works recommends that the Board of Supervisors ratify the Director of Public Works to sign Contract Change Order Number 2-S1 for Post Mile 4.40, Contract Change Order Number 2 for Post Mile 5.10, Contract Change Order Number 3 for Post Mile 5.10, Contract Change Order Number 2-S1 for Post Mile 9.00, and Contract Change Order Number 1-S1 for Post Mile 11.05-11.29. Public Works also recommends that the Board of Supervisors accept the completed contracts, including all change orders approved by Public Works for this project, and approve the final claims for payment.
