Crystal Springs Reservoir Projects Update

Heavy truck traffic is expected this coming Wednesday, October 12^th along Skyline Blvd. and Crystal Springs Road. 90 cement trucks will deliver concrete for the Lower Crystal Springs Dam stilling basin beginning at 2 a.m. on Wednesday and continuing until 5 p.m. (The pour was originally scheduled for earlier this week and postponed due to the storm).

Heavy rain this week also postponed a necessary 2-day closure of Sawyer Camp Trail. A trail closure is anticipated the third week of October…stay tuned for the exact dates!

Underwater seismic construction in Lower Crystal Springs Reservoir near the southern trailhead to Sawyer Camp Trail is progressing rapidly. Hikers on Sawyer Camp Trail will see more boats and other equipment in the water this week.

Everything that enters the water is carefully cleaned under the supervision of marine engineers and wildlife biologists. Protecting water quality and native species is top priority to the project team! The yellow floating booms in the water are silt curtains – an underwater curtain that keeps species out of the work zone and sediment inside. Similar underwater work continues in San Andreas Lake, west of the town of San Bruno.

Near the northern trailhead of the San Andreas Trail, you may also notice PG&E gas-line testing work currently underway (scroll down to see story and photo from August 24, 2011).

Construction Update at Peninsula Watershed Reservoirs

Silt curtains to protect species and water quality

delivered to San Andreas Lake: May 10, 2011

Barge and Dive Boat Launching at San Andreas Lake:

Does the water level appear low to you at San Andreas Lake? It will continue to get slightly lower to accommodate upcoming underwater seismic improvements. You may also see our crew transporting large marine equipment near the trailhead to San Andreas Trail and the northern entrance to the Sawyer Camp Trail.

The construction team must use the Hillcrest Gate entrance for water craft and other large equipment, which may cause delays on Hillcrest Blvd. (near Skyline in Millbrae, just west of 280). Large deliveries are expected over the next couple of weeks, with work in the reservoir taking place all summer.

If you frequently access Sawyer Camp Trail from Millbrae’s northern trailhead, the trail will remain open! Follow us on Twitter for real-time updates about activities: http://www.twitter.com/sawyercamptrail.

Pulgas Water Temple Temporary Closure:

Further south in the Peninsula Watershed (along Cañada Road), the Pulgas Water Temple is closed as of Monday, May 23rd and is expected to reopen in late summer 2011. Please subscribe (see right) in order to receive an email when the temple reopens.

Peninsula Watershed Construction Update

Both Sawyer Camp Trail and San Andreas Trail remain open…and spring weather is finally here!

Neighbors and hikers in the area of San Andreas Lake may see work throughout the spring and summer along the shore. The ongoing installation of silt curtains into the reservoir protects water quality and keeps fish and other species out of the work zone. Divers will perform seismic upgrades at depths of over 100 feet. These upgrades enhance our ability to transmit raw water from San Andreas Lake to the nearby Harry Tracy Water Treatment Plant.

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!
