TBM Making Excellent Progress!

The Tunnel Boring Machine (TBM) boring the New Crystal Springs Bypass Tunnel continues to make excellent progress.

As of Monday, January 25th, tunneling has progressed 1,715 feet out of approximately 4200 feet (41%).

The recent earthquakes in California and around the world are a good reminder that a major earthquake can (and likely will) strike the San Francisco Bay Area at any time. This new tunnel will help ensure water delivery and quality after a major earthquake.

Pipeline Dewatering to Begin near Tartan Trail Road

In late January 2010, the SFPUC and its contractors are planning to drain a water pipeline located off of Tartan Trail Road in Hillsborough as part of the New Crystal Springs Bypass Tunnel project located on Polhemus Road. Please see map for detailed location of work.

The dewatering of the pipeline is necessary for the eventual completion of a new critical pipeline to carry water under Polhemus Road and to ensure delivery of drinking water after a major earthquake.

What Neighbors near Tartan Trail Road Can Expect:
SFPUC and contractor crews will mobilize equipment in late January and park trucks on the existing gravel parking area off of Tartan Trail Road on SFPUC Right of Way property (please see map on reverse for location).
Dewatering will take place 150’ north of Tartan Trail Road and will take place 7 days per week. Crews may be on site 7 days a week between 7am and 6pm.
Overhead tree limbs will be moved for construction access and allowed to return to original position. Minor limbs may be removed to prevent safety issues. The dewatering site will keep wildlife from harm by installing an exclusion fence adjacent to San Mateo Creek.
Approximately six people will be on site daily for the first week, with fewer on site during the remainder of the work.
Dewatering activities will include use of a crane, trucks, a WhisperWatt generator and pumps. Water will be safely discharged into San Mateo Creek following all environmental guidelines as specified by regulatory agencies.
The use of equipment for this project is not expected to exceed noise limits established by the Town of Hillsborough. Mitigations for noise such as acoustical blankets will be provided if needed to conform to noise limits.
Activities will take place at this site into April 2010. Upon completion, crews will remove all equipment.

Tragic Earthquake in Haiti a Shocking Reminder to Store Water and Be Prepared

The devastating and tragic 7.0 earthquake in Haiti on January 12th is a shocking reminder for all of us to be prepared for a major earthquake to strike the San Francisco Bay Area at any time.

Store at least one gallon of water per person per day to last at least three days after a major disaster. Store additional water for houseguests and pets. Store water away from sunlight and heat and replace every six months. Learn more about getting prepared by visiting http://www.72hours.org/.

Neighbors Tour South Shaft Site Following 4.1 Earthquake

Just minutes before the start of their New Crystal Springs Bypass Tunnel South Shaft tour on January 7th, San Mateo neighbors Howard McDonel, Helmut Schagerer, Erwin Hagele and Nick Lolonis heard about the 4.1 earthquake epicentered on the Calaveras Fault near Milpitas. Howard felt it, while the others did not. They toured the construction site and discussed engineering and construction methods being used to build the tunnel and pipeline.

The relatively small earthquake is a good reminder of the race against time the San Francisco Public Utilities Commission faces to seismically upgrade the aging Hetch Hetchy water system before the next big earthquake.

San Francisco Bay Area residents can get prepared for the next big earthquake by storing at least one gallon of water per person to last at least 3 days following an earthquake. Learn more at http://www.72hours.org/.
