BACKGROUND
The November 2025 storms caused a small landslide that undermined about 33 linear feet of the roadway edge, leaving part of the asphalt unsupported and creating a steep drop down to a private driveway. To ensure the future stability of the road and provide public safety, staff propose to repair the damage by installing a new rock slope protection (RSP) buttress to stabilize the downhill shoulder of 4620 Redwood Road at a 1:1 slope, about ten feet high, averaging five feet in thickness. Following installation of the RSP, about 100 feet of the damaged road surface will be reconstructed or repaved. The Engineer Estimate to repair the roadway is $260,000.
Fiscal year 2026-27 recommended budget will include $7 million for all 2025 November Storm Projects construction from the release of designation for fiscal uncertainty. It will be budgeted in RDS01 “November 2025 Storm Roads CIP.” As each project moves forward, budget will be reallocated from RDS01 to specific projects. The Plans and Specifications are complete and ready for approval by the Board of Supervisors. Staff will return to the Board of Supervisors at the time of award to present a detailed project budget based on the lowest responsible bid.
Requested Actions:
Approve Plans and Specifications for the “Redwood Road MPM 5.41, RDS 26-22” and authorization to advertise for sealed bids.
