Upper Alpine Road Bank Protection Project

Post Date:07/03/2014 12:09 PM

Road Work Ahead The Town of Portola Valley will be performing a road bank protection project on a short 100' stretch of upper Alpine Road just uphill of the green gates near the 5500 block area. Work is scheduled to take place between September 11, 2014 - October 31, 2014, weather permitting. The repairs will include drilling and installing piers along the roadside to reinforce the roadway bank and paving a new road surface.

As you are aware, this section of Alpine Road is extremely narrow. Due to the very limited work space and heavy machinery involved in the project, it will be necessary to close the roadway and trail on certain days to through traffic during the work hours of Monday-Friday 8:15am-5:00pm. Due to the lack of turn around space for vehicles, detour signs will be placed well in advanced at the intersections of Alpine/Willowbrook and Alpine/Joaquin. 

In addition, you may have also received a notice from the County of San Mateo Public Works Department about a separate roadway protection project they are performing on Alpine Road towards Joaquin Road in the unincorporated area. That project is scheduled for August 19, 2014 to October 31, 2014. The Town will be coordinating traffic control with San Mateo County Public Works to minimize inconveniences but we still ask residents to plan ahead. San Mateo County Public Works, Robert Enriquez can be reached at 650-363-4100. 

We are aware there will be residents who will be inconvenienced by this work and we ask for your advanced planning, cooperation, and understanding. The construction window for these types of projects are subject to State regulatory requirements due to the nature of the surroundings and weather constraints. This project will result in a retaining structure and bank protection that will help mitigate potential erosion of the roadway. It is our intention to complete this work prior to the rainy season. 

Additional information, updated project schedules, and traffic detour plans will be available on the Towns website under information for residents, Public Works projects. If you reside in this area, we encourage you to contact us so we can keep you posted on any traffic control updates. If you have any questions about the project, please call 650-851-1700 x 216 or email CheyAnne Brown or Howard Young, Public Works Director. During construction activities, the inspector Tom Anderson can be reached at (831) 915-3395.
