Not your ordinary Holiday Mixing

Here at Calaveras Dam, we are not mixing your typical holiday cookie dough. For 24 hours a day and 5 days a week, our project teams have been mixing soils for site stabilization. This process is necessary to stabilize the foundation of our disposal area for excavated materials in order to construct the dam.

Deep Soil Mixing is a soil treatment where soil is blended with cement and existing materials. In deep soil mixing, powerful augers are used to mix slurry, thereby stabilizing it for construction purposes. Below are photos of our work, day and night.

The SFPUC and the Town of Sunol Celebrate the Holidays

Pizza, cider and rock samples! The SFPUC’s Holiday Open House at the Sunol Event Center was the place to be last Thursday night!

Sunol residents mingled with their neighbors and engaged in lively conversations about the history of the valley with SFPUC staff. Guests played with rock samples from the Calaveras Dam, marveled at construction photos of the New Irvington Tunnel and enthusiastically shared their vision for the proposed Alameda Creek Watershed Center.

Residents also had the opportunity to learn about other ongoing projects in the area including: the San Antonio Backup Pipeline; San Antonio Pump Station; Alameda Siphon #4; Sunol Valley Water Treatment Plant; Town of Sunol Fire Suppression System; and the Watershed and Environmental Improvement Program and Bioregional Habitat Restoration Program.

The smell of homemade banana bread and hot apple cider filled the air as guests enjoyed freshly baked artisan pizzas topped with locally grown vegetables from Fred Hemple and Jill Shepard’s Baia Nicchia Organic Farm. Our youngest guests decorated their own ornaments and bookmarks.

Thank you to those who were able to attend our holiday event.

To all of our neighbors in the Sunol Valley and folks we’ve had the pleasure of working with this year, we want to wish everyone a very happy holiday season!
