Stormy Weather Necessitates Swing Shift in Crystal Springs Reservoir Area

Night work will be ongoing adjacent to the Sawyer Camp Trail area -- from 3 p.m. to 11 p.m., Monday through Saturday –- as the project team makes up time due to rain delays and the relocation of a sensitive species (an unexpected neighbor…bats!) As most construction area noise is below the decibel level of nearby Highway 280, recreational users of the area are unlikely to notice the change in work hours.

If you live in the gorgeous hills above the Lower Crystal Springs Dam, you may see additional night-time illumination below Highway 280. The work crew has taken extra care to ensure these lights point downward, rather than in your direction!

Please do not hesitate to contact us with any questions or comments at (866) 973-1476, 24 hours a day.

Biologists carefully relocate bats from the roof of building slated for demolition; March 17, 2011.

Update: Work Begins at San Andreas Lake and Continues at Sawyer Camp Trail

Is the San Andreas Trail one of your regular hiking spots? If so, you may see workers near San Andreas Lake preparing for construction with fencing and some tree cutting. Both are necessary steps to protect the environment as construction starts. San Andreas Trail will remain open for everyone throughout construction.

Not far from the southern entrance to Sawyer Camp Trail, crews are installing support columns for the foundation of the new Crystal Springs Pump Station. Noise should be minimal, but ground vibrations may be felt near the trailhead (Monday to Saturday, 7 a.m. to 5 p.m., ongoing to mid-March).

Please Be Aware: Parking may become more limited near the Sawyer Camp Trailhead, as construction activity increases. The project team realizes that parking is already difficult at Sawyer Camp Trail, and will make every effort to preserve access. Stay tuned for more details!

Please contact us any time with questions or concerns. 24 hours a day, toll-free: (866)-973-1476
