2024 Road Sealant – Phase 2

Description

Overview

The 2024 Road Sealant Project (Phase 2) includes crack sealing, slurry sealing, cape sealing, microsurfacing, and refreshed traffic striping on approximately 11 miles of roadway in West Marin.  The preservation treatments selected for this project are based on the current condition of the road, utility coordination and efficient road groupings. These types of sealant projects represent relatively low-cost improvements (compared to roadway rehabilitation types of projects) that prolong the effective life of roadways in good/fair condition.

Funding

The estimate cost for this project is $2,000,000 and it will be funded by the County's Road & Bridge Fund.  

Traffic Impacts

Construction will take place during the daytime hours with traffic control measures.  Sealing work is a relatively quick compared to paving work, and typically requires only one day of significant traffic impacts per road segment.  For arterial and collector roads, expect traffic control measures and lane closures with 10 minutes traffic delays during work hours.

Property owners/residents along the roads scheduled for sealing are given advance written notifications ahead of any work that requires their road to be closed in order for them to have adequate time to prepare.

Some of the selected road are: Bear Valley Road (from Highway 1 to Sir Francis Drake Blvd): Nicasio Valley Road (from Sir Francis Drake Bvld to milepost 4.00); Lucas Valley Road (from Westgate to Big Rock); Pt. Reyes-Petaluma Road (from Platform Bridge Road to CA Highway 1); Sir Francis Drake Blvd (from Pine Hill to Pierce Point Rd).
