A Family Connection to the Old Calaveras Dam

We at the Calaveras Dam Replacement Project were extremely honored to host a very special guest, Geneva Barrett (Hunt). She was accompanied by her daughter, Debbie and her son-in-law, Randy  of Dublin, California.

Geneva has a special connection to the old Calaveras Dam. Her father, Frank Hunt, worked on the second Calaveras Dam (the first dam slumped under its own weight in 1918). The second Calaveras Dam was built between 1918 and 1925. Frank Hunt was a civil engineer on the project and operated a drag line.  Geneva was born in Sunol in 1927.

The late Frank Hunt circa 1920's.

After the dam's completion, her father relocated the family to Oregon where he continued to work on dams in and around the the state. Geneva recalls her dad as being very dedicated to his profession and to his family. During those times, her father worked all week at his designated job site and came home during the weekends only. She was one of twelve kids.

Geneva told us that seeing the old dam was on her bucket list. We were so pleased to meet her and her family.

See you around the Valley!

Loma Prieta Earthquake Anniversary Week - The New Irvington Tunnel

Happy Friday

This week marks the anniversary of the 1989 Loma Prieta Earthquake. 

We've been blogging about the San Francisco Public Utilities Commission's efforts to seismically upgrade our water system for many years now. The $4.8 billion Water System Improvement Program is more than 96% complete as of this writing. The water system that supplies water to 2.7 million customers in four Bay Area counties is much more earthquake ready today than it was 5 years ago. 

In honor of the Loma Prieta Anniversary week, we wanted to remember a post from October of 2013 when a crucial seismic project for the Water System Improvement Program achieved a huge milestone. Final hole through. 


Miners worked long hours in the New Irvington Tunnel .

The New Irvington Tunnel Project ,which went into service in February 2015, is a new 3.5 mile long seismically designed tunnel. We mined the tunnel from different directions, and the moment the two teams met underground to complete the digging is called Final Hole Through.

See the October 2013 Story here.

Honoring Construction Safety Week in the Sunol Valley


With so much heavy construction work underway in the Sunol Valley, it is easy to forget that the men and women in the construction industry perform dangerous work often in difficult conditions to upgrade the Hetch Hetchy Regional Water System.

It is a good thing that the construction teams working on the two projects in full swing in the Sunol Valley keep safety in mind every single day.  However, this week was a little different. The teams at the Calaveras Dam Replacement Project and the Fish Passage Facilities within the Alameda Creek Watershed underwent additional trainings and reminders this week.

Why?

The first week of May is National Construction Safety Week.  Global construction industry leaders, including our contractors, joined together to form industry safety forums and an initiative called ‘Safety Week.’ The mission of Safety week is to raise awareness within the construction industry ensuring “We are Stronger and Safer Together.”

How strong?

Here in the Sunol Valley, the number of recordable workplace incidents is well below the industry average. At our Fish Passage Project, workers have clocked in over 70,000 work hours since April 2016 with zero recordable incidents.  At the Calaveras Dam Project, the largest project in the Water System Improvement Program has worked over 220,000 work hours since July 2016 with zero recordable incidents. 

Working in heat and rain, on large earth-moving equipment or in tight spaces next to a creek, our crews are showing that every week is safety week.

We are proud of our teams out in Sunol Valley! Stay safe out there.

Spring Wildflower Festival Draws Crowds to Sunol Regional Wilderness


This past weekend, the San Francisco Public Utilities Commission (SFPUC) joined an estimated 1,000 attendees at the 2017 Spring Wildflower Festival, hosted by the East Bay Regional Park District.

The beautiful sunshine, wildflower blooms, nature hikes, and live music drew families from all over the Bay Area to Sunol Regional Wilderness. Over 300 kids stopped at the SFPUC resource booth to create their very own personal paw print necklaces while staff shared information to residents about our Sunol Valley projects underway including the Sunol Yard upgrade, construction of the Fish Passage Facilities Project within Alameda Creek Watershed and the Calaveras Dam Replacement Project.

We hope that you were able to experience this awesome event and enjoy the wildflower season as much as our staff did. See you around Sunol Valley!

Photo Friday From the Fish Passage Project on Alameda Creek

Happy Photo Friday, Everyone!

Ever wonder what a fish ladder looks like from the inside?

You are about to find out, courtesy of our Fish Passage Facilities within the Alameda Creek Watershed Project. The project's goal is to support the restoration of steelhead trout to the Southern Alameda Creek Watershed by building a fish ladder around the SFPUC's Alameda Creek Diversion Dam, in addition to other fish-friendly improvements on the structure.  

Construction is expected to be complete in fall 2018.

Celebrating Amazing Women Near You

Just this week, we celebrated International Women’s Day on March 8th. March is also the beginning of National Women's History Month. In honor of the contributions of hard-working women everywhere, we wanted to highlight a few fabulous women who happen to work at the Calaveras Dam Replacement Project whose daily contributions ensure the success of this critical project. 

Eunice Lee, Field Engineer, Sukut Construction

As an alumna of the UC Irvine Civil Engineering program, Eunice has been working on heavy civil construction projects since 2010.  As part of the contractor’s team, Eunice is a field engineer who specifically oversees the installation of geotechnical instrumentation and the permanent power system for the future replacement dam.  Eunice truly enjoys being a part of this team working with so many experts and experienced individuals to build something great. 




Karene Salaam, Project Controls Analyst, Black and Veatch

Staff who make important contributions to the project don’t always work in the field. We have a team of people whose task it is to track project costs and spending. On a job the size of the Calaveras Dam Replacement Project, this is no simple task. Karene Salaam is part of the Construction Management team and oversees the preparation of cost reports, progress charts, manpower plans, equipment and material costs and project schedules.  Her careful review and analysis ensures the San Francisco Public Utilities Commission has close financial oversight of all project spending by the construction contractor and the subcontractors.



Carrie Dovzak, Geologist, Environmental and Naturally Occurring Asbestos Compliance MonitorSan Francisco Public Utilities Commission (SFPUC)

Carrie Dovzak has worked for the SFPUC for 10 years, the last 6 1/2 of it working on Sunol Valley projects. It is Carrie's job to monitor construction activities to ensure compliance with environmental regulations and protections. She studied geology after traveling the world with her family - a perk of her father working for Pan American Airlines. After graduating, she mapped landslides in Northern Italy before returning to the U.S. to join her family. She continued her studies in Engineering Geology and Environmental Education at San Jose State and Hayward State. "Everyone should take a few classes in geology, you see the world in a completely different way!" she insists.

Ritu Gyawali Giri, Senior Engineer, Piping and Pipeline, Sukut Construction

Ritu Gyawali Giri is part of the outlet works team. She and her team focus on the new piping and pipelines that allow the SFPUC to take water out of the reservoir to our customers. She began in the construction industry in 2002, as a Site Engineer in Nepal. She has worked on projects all over the world, from Asia to Africa to the United States. Ritu relishes working through the geographical and environmental challenges to build the new Calaveras Dam. She is delighted to be a woman engineer working at the Calaveras Dam Replacement Project.

From Acorns to Oaks


What do we see here looking down this plastic tube?


These are acorns collected from the Sunol Valley. For what you ask? We are planting over 150 Oak trees at the Calaveras Dam Replacement Project. As a commitment to the environment, the tree plantings are part of our mitigation to restore oak woodland at our project site. We are also committed to re vegetating all areas with annual grassland where oak woodland is not appropriate. 


Among the species being planted are the Coast Live Oak (Quercus agrifolia) and the Blue Oak (Quercus douglassii). Historically, oak trees are slow growing and can take as long as two to three decades before they begin to provide significant shade. Winter is an ideal time to plant to allow the tree to focus on root growth. 




Some oaks can send a tap root down as deep as five feet in the first year of growth. To help the acorns sprout, and to avoid being dug up by squirrels and birds, they are placed in the plastic tubes right into the ground. The tubes also protect them from hungry herbivores –like deer - and provide a great micro climate for the trees to thrive. 

The next photo shows our oak tree plantings in an area we are no longer working in, the left abutment of the dam, located at the Calaveras Dam Replacement Project. 



See you around the Valley!

What's on Tap in Sunol Valley?



The New Year has brought much needed rainfall to the Sunol Valley. Despite the winter weather, our teams are continuing the important work to seismically upgrade the facilities that deliver drinking water to 2.6 million Bay Area customers. These projects are part of the $4.8 billion Water System Improvement Program (WSIP). The San Francisco Public Utilities Commission (SFPUC) is the owner and operator of the Hetch Hetchy Regional Water System. In addition, other work, such as work on the Alameda Creek Watershed Center and upgrades to our Sunol Yard, are also underway this year. 

Calaveras Dam Replacement Project

Work is still underway to replace the existing dam with a seismically-robust dam in order to restore its historic storage capacity. Rebuilding this dam and filling the reservoir is crucial to the reliable water supply of our customers. Over seven million cubic yards of earth and rock materials have been excavated. We have started to construct the new dam. Crews have constructed a new tower and shaft with five adits which connect outlet pipelines to the reservoir. The new 1550 ft spillway was completed in April 2016. The dam and all the outlet works have been designed to withstand the force of a 7.25 magnitude maximum credible earthquake from the nearby Calaveras Fault. The project is over 78% complete.

Due to recent storm impacts, portions of Calaveras Road remains closed to the public on 7 days a week. Please visit sfwater.org/Calaverasroad for more specific details regarding the closure.

Fish Passage Facilities within the Alameda Creek Watershed

Construction for the Fish Passage Facilities within the Alameda Creek Watershed began earlier in 2016. The Calaveras Reservoir collects water from Alameda Creek by means of the Alameda Creek Diversion Dam (ACDD), a 1.8-mile-long Alameda Creek Diversion Tunnel from other streams that flow directly into the Reservoir.

The project will improve the current facility and develop fish passage facilities within the Alameda Creek Watershed. This important work will support restoration of steelhead trout to the Watershed. The project will construct a fish ladder to facilitate fish passage around the existing Alameda Creek Diversion Dam. The project is approximately 30% complete and project completion is expected in Fall 2018.

Alameda Creek Recapture Project

The proposed project would recapture a certain volume of water that would be released and bypassed at Calaveras Dam and Alameda Creek Diversion Dam. The recaptured water would be pumped from an existing quarry pit (Pit F2) in the Sunol Valley, downstream of the compliance points for the bypasses and releases below the ACDD and Calaveras Dam, respectively.

The project would utilize the natural infiltration of water into the ground in the vicinity of Pit F2, and the recaptured water would be transferred to the SFPUC water system via either the San Antonio Reservoir or the Sunol Valley Water Treatment Plant. The recapture operation would be conducted within the SFPUC’s existing pre-1914 appropriative water rights. 

The Draft Environmental Impact Report was released in November 2016. Construction is expected to begin in Fall 2017 and last for approximately 18 months.

Sunol Yard & Alameda Creek Watershed Center

Construction of upgrades to our Sunol Corporation Yard (located on SFPUC lands near the Sunol Water Temple) are expected to begin in February 2017 and last approximately 22 months.  

Please note that the Sunol Water Temple will be closed during construction to protect the safety of members of the public passing through the area. The Sunol AgPark will remain open to farmers during construction.

Alameda Creek Watershed Center in Sunol and work on the Education Master Plan for the Center continues in 2017. The Center design continues to undergo value engineering, and results are expected in early 2017.  Construction of the Native Plant Nursery for the plants that will be in the new Sunol Yard and Watershed Discovery Trail at the Center will also begin in 2017.

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.

Talkin' Turkey


There are turkeys crossing the road just about everywhere you look on Calaveras Road. 

These two make a nice pair as one watches while the other preens.  Turns out preening is just a fancy word for keeping your feathers clean and looking pretty.  Males find this comes in handy when they are showing off and courting a mate.




This got the Calaveras team talkin’ turkey and exchanging fun facts about this animal – just in time for the upcoming Thanksgiving holiday.

Here’s a few:

  • Where did turkeys get their name?  They are not a native species and since they were imported by Turkish merchants, the English took to calling them turkeys.
  • How can you tell a turkey’s gender?  Believe it or not the droppings give a great clue:  males produce spiral shaped poop and females poop resembles the letter J.
  • Ben Franklin is famous for having had had a special place in his heart for turkeys.  An eagle, he wrote in a letter to his daughter, had "bad moral character." A turkey, on the other hand, was a "much more respectable bird."
  • And finally, turkeys can run at speeds of up to 25 miles per hour.  Might come in handy if they don’t want to be part of the upcoming festive meal…

However you spend the upcoming holiday, we wish you and yours the very best!

We here feel we have a lot to be thankful for.

See you around the Valley!

Creepy Crawlies at Calaveras Dam


Happy Halloween from the Calaveras Dam Replacement Project! 

The Sunol Valley is naturally decorated for Halloween thanks to the “spooky” tarantulas coming out this time of year.  That’s right.  It’s tarantula season and just in time for Halloween. 

The California brown tarantula (Aphonopelma sp.) heads out of its burrow at Calaveras Dam in search of romance.

Turns out that after five plus years of living alone (maturing in a burrow), male tarantulas head out in the fall to find a female mate. 

After mating, the males tend to die a few months later.  By stark contrast, females live for 20 plus years in silk-lined burrows.   Talk about luxury!

And how many babies do these productive moms create?  The number ranges from 75 to hundreds per year.

Our goal is to keep these native species safe from harm while we build the replacement Calaveras Dam.  On a daily basis, our environmental inspectors work closely with construction staff to identify any wildlife on the move through the site. 

Even the spooky ones!  

See you around the Valley!

Sunol's Own Shine at the Calaveras Dam Replacement Project


The $4.8 billion Water System Improvement Program has generated millions of craft hours and thousands of job opportunities for residents of the Bay Area counties served by the San Francisco Public Utilities Commission (SFPUC).

The SFPUC Infrastructure Division’s Workforce and Economic Program Services Bureau works closely with participating contractors to support their efforts to employ local journey and apprentice workers on their projects. 

To date, 48% of all workers are residents of the agency’s 7-county service territory, which includes Bay Area residents who receive SFPUC services or who are impacted as a result of WSIP construction activity. Furthermore, 71% of all apprentice hours have been worked by SFPUC service territory resident apprentices.

On the Calaveras Dam Replacement Project, for example, three residents of Sunol have found successful employment and professional development opportunities as a result of this once-in-a-lifetime project. Two residents, Mr. Anthony DeValle and Mr. Travis Hoxie, have recently completed their respective apprenticeship programs, obtaining milestones such as advanced certifications and more than 3600 hours of on the job training. Mr. Justin Gronley, also of Sunol, is nearing completion of his apprenticeship training, and will soon “journey out”.

Mr. DeValle expressed that, for him, the best part of achieving journeyman status is the opportunity to reach back, “Helping to teach the younger kids by sharing lessons I’ve learned from the more experienced workers.”

Mr. Hoxie agrees that “passing it on” is a major benefit. Travis also liked “gaining more education and developing one’s professional skills necessary to make it in the construction industry.” 

Some of the skills and experience they highlighted while working on the Calaveras Project were: environmental remediation, electrical work, tree cutting, concrete work, dirt work, asphalt, power tools, carpentry, iron work, and traffic control. They even learned complex skills such as rappelling as part of the complex structural work.

Mr. Gronley is especially grateful that the Calaveras project’s timing and location has benefited him. “It’s nice to be able to succeed right out of high school, participate on this project, and still be close to home.”

The Calaveras Dam Replacement Project team would like to congratulate these hard-working individuals on their recent success and express their gratitude for their efforts, and the efforts of all of the workers and staff who are working on this integral project of the WSIP program.
