Water Pipeline Work Resumes at Sawyer Camp Trail

Beginning this week, culverts and streams near Sawyer Camp Trail will fill with water running into the reservoirs…but much of the water is not from the recent heavy rain. Our water department staff will be emptying the pipeline that runs adjacent to Sawyer Camp Trail from January 24 through January 30 to allow for seismic upgrade work. Increased truck traffic will be present on the trail.

Once empty, crews will use a cement mortar lining to strengthen the existing pipeline. Construction activity will be visible along Sawyer Camp Trail at numerous spots from the .5 to 3 mile markers.

Near the San Andreas Dam on the 5 mile marker of Sawyer Camp Trail (the southern end of San Andreas Lake) water trucks will draw water from the reservoir to service the nearby golf course.  The trucks will need to cross the trail in that location a few times each day, during periods of dry weather only. Cyclists heading down the hill from the northern trailhead should use caution!

The trail remains open during construction from sunrise to sunset. Please subscribe (see right) to receive automatic email updates about closures.

Seismic Upgrades to Water System Resume at Sawyer Camp Trail

Work to prepare the trail for rain is underway at several locations along the southern-most 3-mile section. This Saturday two hydroseed trucks will seed hillsides along the trail. The trucks will primarily use water system access roads that run behind the trail. The hydroseed trucks must drive on Sawyer Camp Trail between the 2.3 and 3 mile markers and will be supervised by an environmental specialist at all times.

Next week, construction work to seismically upgrade the water pipeline adjacent to the trail resumes.

Increased truck traffic will be present on the trail Tuesday to Friday (January 17th to 20th). The trail will remain open sunrise to sunset. No trail closures are now scheduled, but we do expect short closures this winter. Please subscribe (see right) to receive automatic email updates.

Before sunrise, our contractor will be moving large equipment down the trail to pipeline work locations. Please do not enter the trail before sunrise! You will be entering an active construction zone.

Construction is taking place near the popular southern-most 3-mile section of the trail. If you haven’t discovered the northern section of the trail yet, now is a great time! The northern trailhead is in Millbrae and can be reached from I-280 via the Larkspur/Hillcrest Blvd. exit (southbound on 280) or via the Millbrae Ave. exit (northbound on 280). Turn west on Hillcrest Blvd. to the trail entrance.

Please contact us 24 hours a day at (866) 973-1476 if you have any questions or concerns about activity near Sawyer Camp Trail.

Critical Water System Work in January 2012

Neighbors of San Andreas Lake, just west of Highway 280 near the town of San Bruno, may have noticed the Lake’s recent low water level. This reservoir is low due to Water System Improvement Program work – not due to recent dry weather. Despite the lack of rain so far this winter, our region’s reservoirs are still in good shape thanks to heavy rain last year. The water level is expected to remain low in San Andreas Lake until our water pipeline is returned to service in late March 2012.

Underwater construction at San Andreas Lake is part of the Crystal Springs/San Andreas Transmission System Upgrade project. This project currently has several work locations throughout the 23-acre Peninsula Watershed. On Monday morning, January 9th three sequential deliveries of large pipe will take place from 7 a.m. to 9 a.m. on Crystal Springs Road in San Bruno just north of the Junipero Serra County Park and San Bruno City Park. Please call our 24-hour phone line if you have any concerns or questions!

Further south near Sawyer Camp Trail, crews will begin mobilizing equipment after the Martin Luther King holiday weekend in preparation for a “shutdown” of the water pipeline that runs next to the trail. Sawyer Camp Trail is expected to be open every day, sunrise to sunset, until the week of January 17th. We do expect a short trail closure that week or in late January. Please subscribe (see right) to receive an automatic email notification as soon as the exact closure dates are announced.
