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 17^th to 20^th). 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.

Also:

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 9^th 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 17^th. 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.

The Crystal Springs Pipeline No. 2 (CSPL2) team will be “potholing” – a limited activity with a small crew – in advance of work in 2012 to replace and upgrade the CSPL2 drinking water pipeline.

Landscaping Work Continues on Polhemus Rd in San Mateo

Crews continue to work at the New Crystal Springs Bypass Tunnel South Shaft site along Polhemus Road in San Mateo.

Hydroseeding began this week and will likely continue into next week (week of December 12th). Neighbors may notice the bright green color on the soil in the area. The green soil mixture contains thousands of seeds that will germinate with the wet weather and grow into grasses in the late winter/early spring. The green color will eventually disappear. Neighbors may see the machine spraying the seeds this week.

Crews will likely finish the landscaping work during the week of December 12th.

Work is moving quickly thanks to the sunny weather. In order to manage dust, crews will continue to wet down the area with water as needed.

Please let us know if you have any questions or concerns. Contact Amy Sinclair at 415-551-4659, asinclair@sfwater.org. After hours and weekends please call 866-973-1476.

Happy Holidays!
