Crunch Time at Edgewood Road

Crews are now across the entirety of Edgewood Road to ensure we meet our environmental deadlines at creek crossings. The new drinking water pipeline is currently installed at two of three creek crossings. In order to complete the final creek crossing and restore the areas by the environmental deadline we may work on Saturdays and Sundays for the next few weekends. The work hours for the weekends approved by the County will be 9am to 5pm.

Restoration is Happening

Restoration is beginning in many places along the Right of Way. Fences are being installed in Redwood City near Fleishman Park and in North Fair Oaks around Marlborough Road. The play structure at Fleishman Park is almost complete and the baseball field at Flood Park is being hydroseeded this Saturday. Commercial restoration plans are nearly finalized for many locations. Curbs and gutters are being replaced in Redwood City between Woodside Road and El Camino Real.

Fence Restoration has Begun!

Fence restoration has started in areas of North Fair Oaks and Redwood City. The project is starting fence restoration at the Right of Way (ROW) near the intersection of Buckingham Ave and Marlborough Ave in North Fair Oaks just west of the CalTrain tracks. From there fence installation will move through areas of Redwood City and into North Fair Oaks west of the CalTrain tracks.

This is a major step in our effort to return the Right of Way to your neighborhoods this fall. Fence restoration includes grading, marking post locations, staking out fence lines and then installing the fence in the ROW. These steps will take place linearly along the fence restoration areas. We anticipate beginning construction on the redwood fences as early as Tuesday.

SFPUC ENCROACHMENT PERMIT HOLDERS: If you own a bisected parcel and have been offered a SFPUC encroachment permit for use of the ROW please ensure that all of your documentation has been returned (including insurance and fees). Without a fully executed permit, you will not have a fence replaced and you will not be allowed use of the SFPUC ROW. A reminder letter will be mailed to you from the SFPUC Right of Way Dept. If you do not know the status of your permit please email baydivision@sfwater.org with your name, address, and your questions regarding your permit.

FAQ:

Are you going to replace my fence?

To qualify for fence replacement by the project, the following conditions must be met:

  • Your property must qualify as “bisected” under the SFPUC’s definition: “A “Bisected” parcel is a private residential lot that the SFPUC right of way bisects or divides that may result in an irregular parcel size or shape or adversely affects access to the parcel.”
  • The SFPUC Real Estate Division (RES) must have received your completed SFPUC Encroachment Permit, proof of liability insurance in the amount of $500,000, and the required payment of $100 for a three-year permit.
  • Your fence must have been removed solely for the purpose of access to the SFPUC Right of Way for construction of the BDPL5 Project.

Fences will be built to standard specifications outlined in the SFPUC’s Right of Way Management Policy. The new fence will be made of wood, measuring 6-feet high, with the top foot made of lattice to allow for visibility. The fence may include a 3-foot wide pass through gate between parcels to allow for SFPUC to periodically access the Right of Way for regular inspections or emergencies. The gate will be secured with a standard latch allowing for an SFPUC lock.

Tunneling has begun at the Bay Tunnel!


The actual tunneling work at the Bay Tunnel project has begun! The tunnel boring machine (TBM) was launched and began tunneling on August 15th. In less than a month, the TBM has tunneled 130 feet of the total tunnel length of approximately 5 miles.

Since the diameter of the shaft is 58 feet in of the trailing gear that will be attached to the TBM is 600ft, these pieces of trailing gear are outside the shaft on the ground being prepared for installation and will be lowered in pieces into the shaft by the gantry crane and assembled once the TBM digs far enough to make room for them. The trailing gear is part of the TBM and includes the operating cabin located 100ft away from the TBM’s cutting head.

As the TBM tunnels forward, the soil being removed will exit through the center of the tunnel on conveyor belts that run out of the tunnel and up the shaft. The conveyor belts leads to the soil pit, an area outside of the shaft where the soil can be loaded onto trucks and hauled off site.

While soil is being removed from the tunnel, construction materials, equipment and tools are constantly being lowered down into the shaft and transported to the TBM heading through the tunnel.. Fresh air, electricity and water, necessary for the optimal working conditions while tunneling are consistently pumped into the tunnel by a series of pipes and power cords. These pipes and cords will continue to be extended into the tunnel as the TBM moves forward so that the TBM has the necessary power and the crews have all of the necessary elements and materials right at hand.

Here are some photos of the Bay Tunnel!

Restoration Scheduled for Mid-September

The construction management team, in conjunction with the contractor, has put together a restoration schedule for both commercial and residential areas. Please see the most recent letter from WSIP Director Julie Labonte (below) which outlines the restoration schedule. Every week we will post details about the exact locations of upcoming restoration in our weekly construction updates on this blog. Stay tuned!

(This schedule, as with all scheduled construction, is subject to change due to unforeseen circumstances. However, we are confident that restoration will proceed in a timely manner within the schedule provided.)

FAQ: Why is Cordilleras Trail still closed?

While pipe installation at Cordilleras trail was completed in May, the contractor needs continued use of the Right of Way for the construction of the valve vault within Pulgas Open Space. This new valve vault will allow the SFPUC to shut off flow to specific sections of a pipeline to perform maintenance and ensure that we will not need to shut down an entire pipe or potentially interrupt water service while work is in progress.

We assure you that as soon as construction in this area is complete and the trailhead can be reopened, we will remove all signage and announce the trail opening here. Until then, please use the other trailheads for your own safety. For weekly construction updates continue to check this blog.
