Two Slides to be Repaired in West Marin

Damage from early 2017 storms to be fixed this summer

San Rafael, CA – A project to repair two slides on roads in West Marin is currently underway by the Marin County Department of Public Works (DPW). It will mark the end of DPW’s slide repair projects made necessary by the extensive damages from the early 2017 storms.

One lane access on Lucas Valley Road while slide repairs are being conducted. Project to repair final slide damages caused by early 2017 storms is underway on two roads in West Marin.

The first slide to be addressed is located on Lucas Valley Road at mile post 9.6, about one mile from the Nicasio Valley Road intersection. Following that, the slide on Sir Francis Drake Boulevard at mile post 18.76 in Samuel P. Taylor State Park will be repaired. Both slides could not be addressed until now because of environmental permitting requirements.

The $1.16 million project began in early August at the Lucas Valley Road location. The work at the Sir Francis Drake Boulevard site is expected to start in late September and both locations are anticipated to be completed by the end of October.

Both slide repairs require the installation of a 90-foot long retaining wall to help prevent future deterioration. Additionally, drainage improvements and updated pavement markings will be implemented along each stretch of roadway.

Temporary traffic signals are in place at both construction locations. During construction, traffic will be controlled with the temporary signals using alternating single-lane access. When heavy machinery is being maneuvered in the construction zone, work crew flaggers will handle traffic control. Construction hours are weekdays from 7 a.m. to 5 p.m. and, while every effort is being made to minimize traffic impact, travelers could experience minor delays during peak commuting hours.

Funding for the project comes from the County’s Road and Bridge Rehabilitation Fund.
