Fish Passage Facilities Project Celebrates Milestone for the Season

This week, the construction teams for the Fish Passage Facilities within Alameda Creek Watershed Project celebrated a few milestones. In preparation for the winter, much work must be completed within the stream. They have completed critical in-water work within the stream bed for the season. This work included completion of the conveyance structure. We also completed a concrete slab for the intake structure. The new intake structure will be constructed next year. All of this was work was completed while maintaining a safety record with zero recordable incidents this year.

Building the Calaveras Dam Replacement Project Safely

Today, the Calaveras Dam Replacement Project took a moment to celebrate another safety milestone. We have reached over 105,000 safety hours with zero recordable incidents for this quarter. 

Our crews from the joint venture of Dragados USA, Flatiron and Sukut Construction have been working both day and night shifts in Sunol Valley. This safety record is very impressive with all the major work that has involved operating heavy machinery, prepping the foundation for the new dam, importing of materials to the site and placing materials to build the replacement dam. Along with a great safety record, we have also brought on over 280 new local hires to the project this quarter. 

Since construction began in 2011, we have reached over 1.4 million total working hours on the job. Our project has not had any lost time recordable incidents since 2012. We strive to maintain our safety culture here at the Calaveras Dam Replacement Project as we continue the critical work ahead to construct the replacement dam.

Spooky Old Adits

We wanted to share a spooky tale from the Calaveras Dam Replacement Project. It seems even state-of-the-art construction projects aren’t without their spooky places.

While moving the rock and soil to make space for the new replacement Calaveras Dam, workers uncovered what looked like holes dug into the area surrounding the existing dam.
The holes are actually adits excavated by the builders of the first Calaveras Dam. 

Technically, an adit is an entrance or tunnel into a mine. Back in the early 1900’s the best way engineers had to explore the rock and soil for a damsite was to excavate adits to look at the underground geology. There are 16 total adits that were uncovered at the site.

We knew about the presence of these adits before we started to dig for the new dam foundation. However, it didn’t ease the creepy feeling workers had when they uncovered them. And some even claim equipment broke down and didn’t work properly while they were working around the adits, as if they were haunted.

The adits are mapped and filled in with concrete or rock to stabilize the ground prior to constructing the new dam on top, and to seal in any spooks that might be still be there…just in time for Halloween!

Photo Friday in Sunol Valley

This week we wanted to share a snapshot of construction underway at the
Fish Passage Facilities in Sunol Valley. The photo below shows the new intake structure and conveyance tunnels under construction upstream of the Alameda Creek Diversion Dam. The Fish Passage Facilities Project is located on SFPUC property adjacent to the Sunol Regional Wilderness. Completion of the project will support the restoration of steelhead trout to the Alameda Creek watershed. Happy Friday!

Remembering Loma Prieta – And Preparing for the Next Big One


Monday, October 17th is the 27th anniversary of the Loma Prieta Earthquake. The 6.9 magnitude quake shook the earth for 15 seconds, took the lives of 67 people and injured almost 3,000 more. There was an estimated $6 billion in property losses. We here at the San Francisco Public Utilities Commission have been preparing for the next big quake ever since.

As the owner and operator of the Hetch Hetchy Regional Water System that serves water to 2.6 million people in four Bay Area counties, we have worked for more than 10 years to repair, replace, and seismically upgrade vulnerable portions of this system as part of the $4.8 billion Water System Improvement Program (WSIP). The program itself is more than 90% complete. Our water system is safer and more reliable today than it was 10 years ago, let alone 27 years ago. Our promise is that we can deliver minimum demand to our customers within 24 hours after a major earthquake. We can make good on that promise because of WSIP.

Here’s just a few reasons why:

* The Bay Tunnel is a seismic lifeline carrying water under San Francisco Bay. It was brought into service on time and under budget in October 2014.

* The New Irvington Tunnel carries water between our East Bay and Hetch Hetchy supplies and our Bay Area Customers. Located between the Calaveras and Hayward Earthquake faults, this seismically designed tunnel allows us to take the existing 88 year-old tunnel out of service for maintenance.

* A new Bay Division Pipeline #5 connects to both of these new tunnels in the East Bay and on the Peninsula to provide greater delivery reliability to our customers. It replaces two pipes that were constructed in 1926 and 1935.

Wait, that’s not all!

We upgraded our Sunol Valley Water Treatment Plant, which treats water from San Antonio and Calaveras Reservoirs. It can now treat enough water to support our entire service territory on its own (160 million gallons of water per day) for up to 60 days after a major earthquake.

Water treatment trains at our newly upgraded Sunol Valley Water Treatment Plant

Two major transmission lines sit on major traces of the Hayward Fault in Fremont. We used cutting-edge technology on our Bay Division Pipelines 3 and 4 to allow one of them to absorb up to 6.5 feet of horizontal displacement and 9 feet of compression while still remaining in service.   
 

A slip joint at the Seismic Upgrades to the Bay Division Pipelines 3 and 4 at the Hayward Fault Crossing allows the pipe to absorb up to 9 feet of compression during an earthquake.


This work is never done. We will continue to replace and upgrade our system pipelines, pump stations, and treatment plants even after the WSIP is complete. We’ll worry about your water so you won’t have to.

Mountain Lions at Calaveras Dam

Just this week at the Calaveras Dam Replacement Project, crews were able to install a special feature to the new Intake Tower roof.  The new intake tower is part of the outlet works that releases water from the reservoir. The special features are roof drain scuppers made of cast bronze in the shape of a mountain lion head designed by artist Manuel Palos and architect Andrew Maloney.

Why a Mountain Lion?
The lion head “grotesque” & “gargoyle” ornament has decorated buildings for thousands of years. In Greek and Roman classical architecture, the lion was a symbol of the fallen hero, guardian of gates, temples, and public buildings. The rain water from the roof is collected in the drain and exits the mouth of the mountain lion.    


Mountain lions are native to the Alameda Creek Watershed. Some construction workers have seen them on site and we even captured footage on our trail camera:

Work on the Drainage System for Calaveras Dam

This week our crews started installation of two drainage pipes which are 100 feet long and 18 inches in diameter. Why are these important?

A major component of earthen fill dams is to control water seepage. Seepage occurs with the continuous movement of water around and through the dam. Earthen fill dams are designed with filter drain materials. The new Calaveras Dam will have filter drains composed of sands and gravel materials, which are being imported to the project site. The filter drains collect the seepage. The water goes into the drainage pipes shown below and flows to a weir building, where it is measured continuously to ensure water is passing safely. Eventually the water will flow downstream to the nearby creeks. The completion of the Calaveras Dam is critical to restore the Calaveras Reservoir to its historic storage capacity of 31 billion gallons of water storage for the Hetch Hetchy Regional Water System.

Successful Celebration of Sunol Ag Park’s 10th Anniversary at the Sunol Water Temple


On Saturday August 13th, the San Francisco Public Utilities Commission (SFPUC) and Sustainable Agriculture Education (SAGE) celebrated the 10th Anniversary of the Sunol Agricultural Park (AgPark) in the East Bay. Located on approximately 18 acres owned by the SFPUC, the Sunol AgPark is a collaborative farm that promotes sustainable agricultural practices, supports beginning and diverse farmers, fosters public education and protects natural resources in the Alameda Creek Watershed.
“Ten years ago, SAGE approached the SFPUC with a novel idea,” said Harlan L. Kelly, Jr. General Manager of the SFPUC. “Create an urban farm on our land between the Sunol Water Temple and our corporation yard. The farm would promote sustainable farming and educate the public about watershed stewardship. This was an entirely new concept to us years ago, and now we support urban agricultural programs throughout the Bay Area.”
The event took place on a very warm summer afternoon in the Sunol Valley, but that didn’t stop attendees from enjoying themselves with the Sunol Water Temple as the back drop. Guests included Norma Camacho the interim GM for Santa Clara Valley Water District, Sunol CAC members, SAGE Board members and staff, farmers from the Ag Park, Sunol neighbors and SFPUC staff who all came together to celebrate this milestone.
During the event, guests had the unique opportunity to tour the working Ag Park discovering the many vegetables, herbs, fruit and flowers grown on the property. All guests enjoyed delicious dishes prepared by local chefs using fruit and vegetables grown at and gathered from the Ag Park. These chefs all come from prominent eateries in the Bay Area including Bar Agricole and Standard Fare among others and donated their time for the event.  The event also received some media coverage from The Independent, a local newspaper serving Dublin, Livermore, Pleasanton and Sunol.
The SFPUC and SAGE commemorated this occasion by unveiling a bronze plaque that will be installed near the Sunol Water Temple to acknowledge SAGE’s hard work and Sibella Kraus’ integral role in the creation and long-term success of the AgPark. The SFPUC’s Commission recognized Sibella Krauss, for her hard work and dedication to this project, with a heartfelt acknowledgement and resolution at their Aug. 9 meeting. In 2017, SAGE will move on to other opportunities and the management of the AgPark will be taken over by the Alameda County Resource Conservation District. However, the farm will continue as it has- providing land for sustainable farming and education.

Safety Milestone for the Fish Passage Facilities Project


Since construction began in April 2016, the Fish Passage Facilities Project within the Alameda Creek Watershed celebrated an important safety milestone this month.  As of August 6th, the construction crews have worked a total of 24,447 hours with no recordable injuries, modified duty or days away from work and the injury rate is well below the national average. 

Major work has included concrete demolition, excavation and drilling work at the site. The Alameda Creek Diversion Dam is located on SFPUC lands adjacent to the Sunol Regional Wilderness Park in Sunol. The project will allow the SFPUC to improve the current facility and to develop fish passage facilities within the Alameda Creek Watershed. This important work will support restoration of steelhead trout to the Alameda Creek watershed. As we continue work to complete the project in late 2018, we applaud Shimmick Construction for making safety a priority every day.

Calaveras Dam Project shows Day Campers how to build their own Dam


It was a hot summer day in the Sunol Regional Wilderness Park. But that did not stop our project teams to meet with a group of energetic kids from the Ridge Runners Nature Day Camp. 

Staff met with the young, curious minds to tell them about the Hetch Hetchy Regional Water System along with what is happening just around the corner at the Calaveras Dam Replacement Project and the Fish Passage Facilities within the Alameda Creek Watershed.

The youth learned about how their drinking water reaches their tap and asked questions about how fish migrate along the fish ladder. The Fish Passage Facilities Project will support the migration of the steelhead trout in Alameda Creek, around the existing Alameda Creek Diversion Dam, when completed in late 2018.

In addition, the kids were able to become hands-on dam builders, designing and constructing their own dams with clay, gravel and sand materials. The soil samples provided will actually be used in the construction of the Calaveras Dam, an earth and rock filled dam, so the campers got to touch the very center of the dam.



Thank you to the Ridge Runners Nature Day Camp for the opportunity to hear about our important projects in the Sunol Valley!

Photo Friday - Tule Elk


Tule elk are a subspecies of elk that are native to only California. Once abundant, they were hunted to near extinction after the Gold Rush.  A small handful of elk were discovered on a private ranch in San Joaquin County in the mid 1870’s and protected by the rancher.

Flash forward, tule elk were reintroduced to the area in Santa Clara County in 1978. The herd split up, and some of them took up residence near our San Antonio Reservoir.  

The ancestors of that herd are still there today, and apparently making themselves available for photo ops by watershed keeper Pat Jones while on his rounds.





Pat spied this gentleman below Turner Dam last weekend.

Have a great weekend, everyone!

Sunol Valley Updates: Calaveras Road Closure and Construction Updates

Here are some important updates that may affect you:

Calaveras Road Closure Starts July 5th

To those who drive or ride Calaveras Road between Milpitas and Highway I-680 through the Sunol Valley: Please take note that Calaveras Road will be closed between Geary Road (just south of the entrance to Sunol Regional Wilderness) to Oakridge Road (near the Santa Clara / Alameda County line) starting July 5, 2016 for 18 months for safety reasons. The closure is weekdays only. 

Why Close the Road?
Although the majority of the materials for the new dam will come from on-site, approximately 300,000 cubic yards of sands and gravels and 150,000 cubic yards of hard rock will need to be imported to the site for construction of the dam. These materials will be imported in large hauling trucks on Calaveras Road. At its peak, truck traffic could amount to an average of one haul truck every five minutes on Calaveras Road during heavy hauling activities. It is not safe for this many large trucks to share the narrow portions of Calaveras Road with cyclists and private vehicles. 

Road Closure Details
  • Where: Calaveras Road just south of Geary Road (entrance to Sunol Regional Wilderness) to Oakridge Road – near the Alameda / Santa Clara County line.
  • When: weekdays ONLY
  • The road will be swept of debris before opening at 6 a.m. on Saturday mornings
  • The road will be closed every Sunday evening at 11:00 p.m.
  • Gates: Two gates will close Calaveras Road just south of Geary Road and at Oakridge Road
  • Emergency First Responders will have access through the closure at all times
  • The entrance to East Bay Regional Park District’s Sunol Regional Wilderness will be open at all times from the north
  • The road will be OPEN on weekends, for specific cycling races and for major holidays.
To learn more about the Calaveras Road Closure, please visit sfwater.org/calaverasroad for more details

Construction Activity to begin in the South end of the Calaveras Reservoir

What
Staring July 5, 2016 thru Mid 2018, increased construction activity will begin in the southern end of Calaveras Reservoir which the project refers to as Borrow Area E. In order to construct the replacement dam, we will need to gather clay materials from Borrow Area E.

What to expect
  • Construction vehicles and earth moving machinery working at the southern edge of the reservoir on SFPUC property.
  • Typical work hours are from 6:00 am to 6:00 pm
  • You may hear back up alarms and some noise from the equipment
  • Traffic: the trucks will stay off public roads for construction work. They will utilize specially-constructed roads within SFPUC property instead
  • The project will not use Marsh or Felter Roads to access the construction areas or to haul materials. 

No Construction Work on the 4th of July
Our construction crews in Sunol Valley will not be working.
We hope everyone has a safe and wonderful Independence Day.

May 31st is National Dam Safety Awareness Day

Each year, the nation commemorates May 31st as National Dam Safety Awareness Day. We have an important dam under construction here in Sunol Valley – the Calaveras Dam. Dams play a critical role in our water supply. 

Why is it important?
  • Calaveras Reservoir, impounded by Calaveras Dam, when full provides half of Hetch Hetchy Regional Water System's Bay Area storage
    • Upon completion, we will have a new seismically upgraded dam with a structural height of 220 feet, a crest length of 1210 feet and width of 80 feet at the crest and 1180 feet at the base
    • It is crucial to the reliability of the water supply of 2.6 million people during emergencies and in times of drought
    Today reminds us just how critical our work is here in Sunol Valley to rebuild the Calaveras Dam.

    The following organizations have joined forces to commemorate National Dam Safety Awareness Day on May 31 - the Deep Foundations Institute (DFI), Association of State Dam Safety Officials, National Hydropower Association, U.S. Society on Dams and American Society of Civil Engineers. Check out their news:

    Sunol Valley Teams Celebrate Memorial Day


    In observance of Memorial day, our construction teams will not be working on May 30th at the Calaveras Dam Replacement Project or the Fish Passage Facilities within the Alameda Creek Watershed Project in Sunol Valley.

    We hope all of you have a safe and wonderful Memorial Day weekend.

    Schedule Update for Calaveras Road Closure
    To those who drive or ride Calaveras Road between Milpitas and Highway I-680 through the Sunol Valley:

    The SFPUC has postponed the start of the closure of Calaveras Road, which was originally planned to begin on June 1, 2016. We will continue to keep you up-to-date on the timing and status of the closure. Calaveras Road is currently open to the public.

    It is important to note that there is still truck traffic on Calaveras Road now between I-680 and the entrance to Calaveras Dam. The speed limit is 25 mph on Calaveras Road in construction zones. Please ride and drive safely on the narrow portions of Calaveras Road.

    We are Stronger and Safer Together – National Safety Week


    This week is National Safety Week. Which means construction contractors across the country emphasize one of the most important factors of the job -- SAFETY. Right here in Sunol Valley, we have over 150 workers working on projects such as building the replacement Calaveras Dam.

    At the Calaveras Dam Replacement Project, crews have worked over 140,000 safe working hours since the beginning of the year, without any recordable safety incidents.  A recordable safety incident is when a worker requires medical treatment beyond first aid and there is a loss time on the job. Our last recordable incident was in October 2014. This is well below the industry average.

    Why is this record special? Because our construction crews at the Calaveras Dam Replacement Project work multiple shifts – both day and night – working with huge machinery, excavating earth and rock, on a very complicated job site in challenging conditions. As we continue work to complete the project, we applaud the joint venture of Dragados USA, Flatiron Construction, and Sukut Construction for making safety a priority here at Calaveras Dam during National Safety Week.

    Check out our time lapse capturing excavation work since the beginning of the project:



    Before sunrise, the Calaveras Dam crews get together for their daily morning safety tailgate

    What’s New in Sunol Valley?

    If you frequent Sunol Regional Wilderness, you may have noticed increased activity in the park. Our crews are kicking off the Fish Passage Facilities within the Alameda Creek Watershed Project. The Alameda Creek Diversion Dam is located on SFPUC lands adjacent to the Sunol Regional Wilderness Park in Sunol and helps collect water in Calaveras Reservoir through a long tunnel. The project will develop fish passage facilities, including a fish ladder and modified screens for steelhead migration into and out of the Alameda Creek Watershed. Alameda Creek has historically supported an impressive diversity of migratory cold water fish, including steelhead trout. This work will help support the restoration of steelhead trout to the Alameda Creek watershed.  Project completion is expected in late 2018.

    What to expect during construction:
    • Sunol Regional Wilderness remains open during construction
    • Park users should anticipate seeing increased construction traffic from the Geary Road entrance and along Camp Ohlone Road, which is the main construction access road
    • Temporary Trail Closures will be needed for large vehicle access and for road improvements. Please use alternative trails to Little Yosemite, such as Canyon View Trail, during these times.
    • Please pay attention to construction flaggers and park signage
    • Construction activity is expected Monday thru Friday from dusk to dawn

    Calaveras Dam Team participates in the US Society on Dams Conference

    Some of our Sunol Valley Project team members are visiting Colorado this week. And they are not visiting to see the snow, but taking part in the United States Society on Dams (USSD) 2016 Annual Conference representing the Calaveras Dam Replacement Project.

    As you know, the Calaveras Dam Replacement Project is the largest project of the $4.8 billion Water System Improvement Program (WSIP) to repair, replace, and seismically upgrade key components of the Hetch Hetchy Regional Water System. 

    Our WSIP Director Dan Wade and Calaveras Dam Project Manager Susan Hou were joined by the members of our SFPUC Engineering Management Bureau at the conference to present on the construction and challenges with the Calaveras Dam Replacement Project.

    The completion of the project is important to the water supply for the Bay Area. 
    Calaveras Reservoir, when full, represents nearly half of all the water storage in the Bay Area for the Hetch Hetchy Regional Water System that serves 2.6 million customers. Calaveras Reservoir is a crucial source of water supply during times of drought and when Hetch Hetchy Reservoir supplies are unavailable for any reason. 

    Our project construction continues and we have moved over 7 million cubic yards of earth and rock materials to make room for the new dam. We plan to start constructing the replacement dam later this year. The project is over 70% complete.

    From L to R: SFPUC Engineering Staff Carman Ng, Tedman Lee, Alisha Reinhardt, USSD President John Wolfhope, Former USSD Executive Director Larry Stephens, SFPUC WSIP Director Dan Wade and Calaveras Dam Project Manager Susan Hou
