Marshall Petaluma Road MP 8.24 Erosion Repair

Description

Overview

Storms caused an embankment failure immediately below the existing retaining wall on Marshall Petaluma Road at milepost 8.24, approximately half a mile south of Walker Creek Ranch. The County proposes to install a rip rap buttress along the slope starting from the bottom of the existing retaining wall to the slope of the creek, which is intended to stabilize the embankment and prevent future erosion.

Funding

The engineer’s estimate is $345,000 and will be funded through the Federal Highways Administration’s Emergency Relief Funds with a local match.

Traffic impacts

There will be one lane access with alternating two-way control through the single lane. Traffic delays will be limited to 5 minutes.
