Capturing Construction in Photos

To our construction teams, Robin is a familiar face who frequently visits the active construction sites to shoot some candid photos of construction and our hard workers. Little did we  know that Robin not only works to document the construction progress but she gains much deserved national recognition while she is at it. For the Water System Improvement Program (WSIP), Robin’s photo of the New Irvington Tunnel Project made the Top Ten for the Engineering News Record (ENR) 2015 Year in Construction Photo Contest. This is a prestigious international construction photography competition, and we are extremely proud that Robin’s photo of our own tunnel was a winner!

About Robin

Robin Scheswohl moved to the Bay Area in 2003 from Philadelphia, PA where she studied photography and later worked with corporate and wedding photographers. She’s been with the SFPUC since 2007, working in the Construction Management Bureau and the Engineering Archives. She is responsible for cataloging and preserving thousands of historic images dating back to the 19th century, as well as documenting the Water System Improvement Program (WSIP) construction projects. SFPUC Engineering Archives Photography has curated public exhibits at City Hall, at the San Francisco International Airport, and the SF American Institute of Architects (AIA) Headquarters. The images are used extensively by the SFPUC and appear in books, periodicals, environmental and engineering studies.

Here is Robin filming at the Bay Tunnel, which is the first tunnel constructed under San Francisco Bay.  Congratulations, Robin!

Construction Activities Resume

 

Construction activities for the Regional Groundwater Storage & Recovery (GSR) and Peninsula Pipeline Seismic Upgrade (PPSU) projects will resume today, February 16, after observing the President's Day Holiday.

Giants of the Watershed

The Peninsula Watershed is home to more than 3000 acres of Coastal Redwood and Douglas Fir. The tall native conifers are particularly important as nesting habitat for certain birds, such as the federally endangered Marbled Murrelet, a stocky black and white seabird that requires large areas of coastal forest canopy in order reproduce in the spring.  We’ll have updates in April and May on this year’s Marbled Murrelet pairs and other watershed wildlife.   

The pristine 23,000-acre Peninsula Watershed also has nearly 4000 acres of native oak and other hardwood forests, plus large expanses of grassland, chaparral, and other habitats, including marsh, riparian, cultivated and lakes. Together, they foster a diversity of ecosystems with their own webs of native plant and animal life. The watershed is also a State Fish and Wildlife Refuge. 

Exploring the Watershed: Endless Opportunities for Volunteer Trail Leaders

Any day is a good day to walk, cycle or ride your horse along the Peninsula Watershed’s Fifield-Cahill Ridge Trail—a 10-mile stretch through old-growth conifer forest, fragrant coastal scrub, and grassy meadows. Ridge Trail events are available by reservation on Saturdays, Sundays and Wednesdays. A wide variety of Ridge trail event itineraries are scheduled year round and are led Ridge Trail Leader Volunteers.

There are openings now to join our diverse corps of approximately 150 trail leaders, whose interests range from fitness to art, gardening, nature interpretation, and more. “The opportunities are endless, and the experience is unique,” said Watershed Natural Resources Manager Joe Naras. “The place gives you the impression that no one else is there.”

What’s On Tap in the Peninsula for 2016?

Our SFPUC teams in the Peninsula are looking forward to a busy 2016! The $4.8 billion Water System Improvement Program (WSIP) might be more than 90 percent complete, but there’s still a lot of work left to complete. We look forward to continuing to share information about our current projects and starting new ones in the New Year. Here are a few highlights of what to expect in 2016.

Regional Groundwater Construction Continues to Charge Forward
The Regional Groundwater Storage & Recovery project charges forward to complete well drilling this year, and then the focus will shift to building well facilities at 13 separate sites in 2016. .


Project team directing concrete pour in South San Francisco

The Regional Groundwater and Storage Recovery project is constructing up to 16 new groundwater wells and associated pipelines and equipment to allow us to store groundwater in wet years for use in times of drought. Learn more about the project here: www.sfwater.org/gsr. Construction started in April 2015 and is estimated to be complete in March 2018?


Seismic Upgrade Success in the Peninsula
The Peninsula Pipeline Seismic Upgrade Project (PPSU) project is wrapping up restoration activities. We anticipate the project to be complete in winter 2016. The construction team is working to ensure that the project’s sites are returned to the same condition before our pipeline replacement work started in summer 2014.

The PPSU project consisted of seismic upgrades to three Hetch Hetchy Regional Water System delivery pipelines located in Millbrae, San Bruno, South San Francisco and Colma. These upgrades make the water system more reliable after an earthquake.

Clearing the Way for New Native Habitat on Watershed Lands
Coming up on the Peninsula Watershed this spring, watershed crews will begin hand-removing pampas grass, periwinkle and other non-native, invasive vegetation from several acres along and near the east side of Lower Crystal Springs Reservoir. Over the years the invasive species have gradually but consistently overcome and displaced the area’s original native grasses and other plants.

This initial brush clearing will be the first step in a long-term comprehensive Bioregional Habitat Program to restore about 150 acres of native grasses and oak woodlands within the 26,000-acre watershed. The program is designed to compensate for impacts to habitat resulting from seismic reconstruction of major drinking water facilities within the watershed.


Crews hand-remove non-native, invasive vegetation to make way for the restoration of our historic native habitats.

Hike, Bike, or Ride the Fifield Cahill Ridge Trail
In case you were not aware, members of the public can hike, mountain bike, or ride their horses through the Peninsula Watershed on the Fifield-Cahill Ridge Trail. Access to the trail is by guided groups by reservation only. Those wanting to experience pristine old-growth forests, grassy meadows and ridgetop vistas should make a reservation on line: here.

Hetchy System Temporarily Out--But High-Quality Water Still Coming In

A couple of weeks ago we reported on the high reservoir water levels on the Peninsula, and how that’s due to the way we manage and adjust them during the rainy months.We maximize our storage here in the Bay Area for later use when we need it, particularly in January when we take the Hetch Hetchy System offline for a few weeks for routine maintenance.

That time is upon us. Now our Crystal Springs Reservoir System goes into high gear, serving all Peninsula and San Francisco consumers with a continuing high-quality supply of stored Hetch Hetchy water plus a small amount of local watershed rainfall.

In short, Hetch Hetchy water enters the watershed through Pulgas Tunnel, and surplus water is released into Crystal Springs Reservoir, where it mixes with
rainfall and local runoff.

The Crystal Springs/San Andreas Pipeline System and the Crystal Springs Pump Station move water north from Crystal Springs to San Andreas Reservoir. From there, the San Andreas Pump Station pumps it on up to Harry Tracy Water Treatment Plant for disinfection and filtration before it is conveyed onward to approximately one million people.  

                                                                  

                                             

         Surplus Hetchy water flowing into Crystal Springs.                                          

At Harry Tracy all hands are on board, according to senior water treatment plant operator Justine James. “We’re operating all our chemical feed systems, pumps and other equipment to produce the higher capacity,” she said.  During the shutdown the plant is currently producing about 80 million gallons per day instead of the usual 35 million per day.   
                                 
And, thanks to recent seismic upgrades, the Crystal Springs Reservoir System is more dependable than ever, with the strength and resilience to withstand the next major earthquake or other natural disaster. 

                                                                                                                                                                                                                   

Tree Removal along El Camino Real between Southwood Drive and Orange Avenue

Beginning in late January, the Regional Groundwater Storage & Recovery (GSR) Project will begin removing approximately 26 trees on the SFPUC’s right of way to prepare for pipe installation along El Camino Real between Southwood Drive and Orange Avenue.

Along El Camino Real, the Project will install an eight inch diameter pipeline Real to connect our regional water customers with emergency water supply wells nearby. Our biologists carefully evaluated these trees, and determined the trees would suffer more damage to their roots and foundation if we were to leave them, causing a safety hazard. Due these factors, their age and health they cannot be saved and need to be removed prior to pipeline construction.

The SFPUC is working closely with the City of South San Francisco’s Park and Recreation Department to replace the trees with new vegetation along the right of way in accordance with the SFPUC’s vegetation management policy. The project team has marked the trees to be removed with ribbons.

Above are examples of the trees to be removed.

During tree removal and pipeline construction, the sidewalk and parking lane along southbound El Camino Real between Southwood Drive and W Orange Avenue will be closed Monday through Friday from 8 a.m. to 6 p.m. 

Indicated above are the locations of the trees to be removed, the sidewalk detour route and parking lane closure details.
