San Francisquito Creek Flood Protection Project: SF Bay to Highway 101

Providing 100-year creek flood protection to more than 5,700 homes and businesses in Palo Alto, Menlo Park and East Palo Alto. 


Updated May 17, 2017

Construction resumes

The construction of flood protection features along San Francisquito Creek that began last summer resumes in May with major work outside the channel through the end of the year. Construction activities within the creek channel will take place from June through October. View the 2017 construction mailer for more information.

Long-term trail closures start May 22 and June 1
We're nearing the major construction work to install floodwalls and widen the San Francisquito Creek channel between Highway 101 and the Bay. During this time, long-term trail closures on both sides of the creek are required for public safety.

Palo Alto trail closures 

East Bayshore Road to Geng Road     Closed April 24 to December 31
Geng Road to Friendship Bridge Closed June 1 to December 1

East Palo Alto trail closures  

Verbena Drive to O'Connor Street      Closed May 22 to December 31
 
These trail closures are continuous and the trails will not be reopened after the work day or on the weekends for safety. During this time, the trails will be removed for the construction activities and replaced upon completion by December 31, 2017.

Please follow all trail closure signage and fencing. The closures are for your safety while the contractor operates heavy machinery and moves equipment along the creek. Only authorized construction personnel are allowed on site.

The alternate routes are designated by the cities of Palo Alto and East Palo Alto.

Note: This closure information based on construction activity is current as of May 2017. As new information becomes available, we will send additional updates.

Thanks for your patience
We appreciate your understanding during construction. We are working with the contractor to minimize impacts as much as practical and provide as much advance notice as possible.

We will continue to share new information on the website and with the email subscriber list.

 

Project summary

The San Francisquito Creek Joint Powers Authority (SFCJPA) is leading a project to protect East Palo Alto and Palo Alto from flooding along San Francisquito Creek between San Francisco Bay and U.S. Highway 101. These communities are at high risk of severe flooding from flows coming down the creek, particularly during high tides. Improving this stretch of about one and a half miles of San Francisquito Creek constitutes the necessary first step in an overall plan to provide more than 5,700 homes and businesses with 100-year creek flood protection during extreme tides and after sea levels rise two feet. 
Visit sfcjpa.org for comprehensive information on the project and adjoining projects related to the creek and Bay shoreline protection, restoration and trail enhancement.

Project specifics and timeline

Design 2010-2016

Permits 

2013-2016              

Construction Summer 2016-2018

Construction will begin in June 2016 and last for approximately two and a half years, with most of the work limited to June through January to protect endangered species in the area.

The San Francisco Bay to Highway 101 project includes excavating decades of sediment build up in the channel, new floodwalls where private property constrains the channel, widening the channel by building a new levee through the Palo Alto Golf Course, and rebuilding the existing levee adjacent to East Palo Alto homes. 

The following activities are planned for the 2017 construction season:

  • Relocating an existing PG&E gas line and East Palo Alto Sanitary Sewer Line under the creek to accommodate the new levee alignment
  • Installing approximately 2,800 feet of steel sheet pile floodwall along the south side of the creek between Geng Road and East Bayshore Road in Palo Alto.
  • Installing approximately 2,000 feet of steel sheet pile floodwall along the north side of the creek between Daphne Way and East Bayshore Road in East Palo Alto.
  • Excavating sediment from the creek channel to widen the creek
    and increase the creek capacity

*Note: These are the projected activities based on the contractor's current schedule and may change throughout the course of the year.

What to expect during construction 

The SFCJPA and Water District are working to minimize construction impacts as much as practical and in accordance with permit requirements and city ordinances. We appreciate your understanding and cooperation as we construct this important flood protection project.

  • Construction work hours are Monday through Friday, from 8 a.m. to 6 p.m. and Saturdays from 9 a.m. to 6 p.m.
  • Majority of construction work will be conducted in and along the creek, within the project’s right of way.
  • No road closures are expected, but may occur only if needed
    and as minimal as possible.
  • Expect typical construction noise during work hours from heavy equipment, such as sheet pile installation rig, excavators, concrete trucks and hauling trucks.
  • A water truck will spray the work area to control any dust from construction activities.
  • Generators may be used to pump water around the project site and back into the creek further downstream.
  • The contractor will store equipment and materials at the O’Connor Pump Station, next to the creek at Verbena Drive and next to the Palo Alto Golf Course at Geng Road.

Traffic impacts and access

  • On the East Palo Alto side of the creek near the O’Connor Pump Station, the Bay Trail/San Francisquito Creek Trail will be intermittently closed as needed during construction. The trail between Verbena Drive and O’Connor Street will be closed from May 22 through December 31, 2017.
  • On the Palo Alto side, the Bay Trail/San Francisquito Creek Trail will be closed from East Bayshore Road to Geng Road from April 24 through December 31, 2017, and from Geng Road to Friendship Bridge from June 1 through December 31, 2017.
  • Friendship Bridge and the trail on the Palo Alto side from the bridge to the Bay is expected to be closed during a portion of this summer and fall. Updates will be shared as new information becomes available.
  • Signs will be posted in advance of a trail closure and alternate routes will be offered whenever possible.

The contractor will access the creek work areas at various locations. Some street parking may be restricted intermittently along the designated access routes.

  • On the Palo Alto side, the access locations are at East Bayshore Road, Laura Lane and Geng Road.
  • On the East Palo Alto side, the access locations are at Verbena Drive, Daphne Way and O’Connor Street.

Safety first

The safety of the community and our employees is our priority. Only construction personnel are authorized in the construction areas. Clear and prominent construction site signs are installed around the project work area. Traffic control or flaggers may be needed at times during work for safety. Water District inspectors will be on site to monitor the contractors and ensure all protocols and ordinances are followed.

Funding partnership

The total estimated cost of the San Francisco Bay to Highway 101 Project is $41.35 million. The project is a partnership among the SFCJPA and its member agencies: the Santa Clara Valley Water District ($28 million), SFCJPA ($8.83 million), City of East Palo Alto ($1.26 million), San Mateo County Flood Control District ($2.06 million), City of Menlo Park ($0.8 million) and City of Palo Alto ($0.4 million). The Water District will administer and manage the construction of levees and floodwalls. The SFCJPA has contracts with PG&E and the East Palo Alto Sanitary District to relocate and improve major utilities, and with the U.S. Department of Agriculture, nonprofits and private firms to protect endangered species and enhance their habitat.
