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:

Sunol Glen School Walk-a-Thon

Well, now it is officially fall. Sure, the Autumnal Equinox was yesterday, but today, more importantly, is Sunol Glen School’s Annual Walk-a-thon!

It is the Sunol Glen Community Club’s largest fundraiser.

We at the SFPUC are pleased and proud to be out there again this year to provide drinking water and moral support to the amazing student participants.

How can you show your support, you ask?

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.
