DISCUSSION:
On Feb. 14, 2017, the Federal Emergency Management Agency declared a disaster for Humboldt County due to severe winter storms, flooding, and mudslides. East Branch Road (6B175) Post Mile 0.36, Oakcrest Drive (6B185) Post Mile 0.10 and Mosswood Lane (6B178) Post Mile 0.15; located in the Benbow area of Humboldt County, experienced roadway failures due to saturated embankment soils slipping beneath the roadway. The embankment failures resulted in lane closures and additional hazards to the small rural community of Benbow.
On Apr. 16, 2018 and May 21, 2018, the Humboldt County Department of Public Works (“Public Works”) received approval from the Federal Emergency Management Agency to proceed with the East Branch Road (6B175) Post Mile 0.36, Oakcrest Drive (6B185) Post Mile 0.10 and Mosswood Lane (6B178) Post Mile 0.15 Storm Damage Repair Projects. Public Works prepared plans and specifications based on topographic surveys of the damaged areas prepared by Points West Surveying Company and Public Works, geotechnical studies prepared by Crawford and Associates, and design engineering reports prepared by GHD and Public Works. The work consisted of constructing rock slope buttress, reinforcing embankments with geosynthetic material, installing surface and subsurface drainage facilities, restoring the road surfaces to pre-disaster conditions with aggregate base and hot mix asphalt, and installing sediment and erosion control items.
On June 2, 2020, the Humboldt County Board of Supervisors authorized the Clerk of the Board to advertise the East Branch Road (6B175) Post Mile 0.36, Oakcrest Drive (6B185) Post Mile 0.10, and Mosswood Lane (6B178) Post Mile 0.15 Storm Damage Repair Projects for bids. On June 30, 2020, the County of Humboldt received five (5) bids for the projects. The contracts were awarded to Mercer-Fraser Company, the lowest responsible bidder, on July 28, 2020. The award amount was Two Million Forty-One Thousand Four Hundred Forty Dollars and Fifty Cents ($2,041,440.50), and contract change orders executed during the project increased the authorized amount by Thirty-Two Thousand Eight Hundred Twenty-Nine Dollars ($32,829) for Contract Number 217516 [East Branch Road (6B175) Post Mile 0.36] and decreased the authorized amounts by Twelve Thousand Seven Hundred Eighteen Dollars and Forty-Nine Cents ($12,718.49) for Contract Number 217518 [Oakcrest Drive (6B185) Post Mile 0.10] and by Eight Thousand One Hundred Forty-Six Dollars and Forty Cents ($8,146.40) for Contract Number 217341 [Mosswood Lane (6B178) Post Mile 0.15].
Public Works 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.
