Body
SOURCE OF FUNDING:
Road Fund (1200); Federal Highway Administration Emergency Relief Storm Damage Funds
DISCUSSION:
On March 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 (3C010) Post Mile 6.50, in the Petrolia-Honeydew area of southern Humboldt County, experienced roadway settlement and shoulder failure. Emergency temporary repairs were done at the time of the disaster to maintain essential traffic.
On Sept. 28, 2020, the Humboldt County Department of Public Works (“Public Works”) received funding approval from the Federal Highway Administration to proceed with the Mattole Road (3C010) Post Mile 6.50 Storm Damage Repair Project. GHD subsequently prepared plans and specifications for the project based on a topographic survey of the damaged area prepared by Humboldt County Public Works Survey Division and a geotechnical study prepared by Crawford and Associates. The work consisted of constructing geosynthetic reinforced embankment, installing deep sub-drainage and storm drainage systems, restoring the roadway to original width, and installing sediment and erosion control items.
On Nov. 10, 2020, the Humboldt County Board of Supervisors authorized the Clerk of the Board to advertise the Mattole Road Post Mile 6.50 Storm Damage Repair Project for bids. On Dec. 15, 2020, the county received three (3) bids for the project. The project agreement was awarded to GR Sundberg, Inc., the lowest responsible bidder, on Jan. 12, 2021. The award amount was $663,174, and contract change orders executed during the project increased the authorized amount by $144,327.52. This increase is due to costs associated with processing excavated material to meet backfill specifications and additional work required to align the reconstructed section with the existing roadway.
Public Works recommends that the Board of Supervisors ratify the Director of Public Works to sign Contract Change Order Number 2; accept the completed contract, including all change orders approved by Public Works for this project; and approve the final claim for payment.
FINANCIAL IMPACT:
Total construction costs for this project are $807,501.52. Progress payments totaling $708,133.87 have been paid, and the final claim for payment in the amount of $99,367.65 is outstanding.
This project was funded through Federal Highway Administration Emergency Relief Funds (88.5%) and the Humboldt County Road Fund (11.47%). Construction costs were included in the fiscal year 2021-22 Road Fund budget unit (1200321). This project has no impact on the General Fund.
STRATEGIC FRAMEWORK:
This action supports your Board’s Strategic Framework by providing for and maintaining infrastructure .
OTHER AGENCY INVOLVEMENT:
