Thursday and Friday (December 8^th and 9^th) from 9 a.m. to 3 p.m., portions of Crystal Springs Road between Skyline Blvd. and Polhemus will periodically be closed to one lane. Flaggers will be present to direct traffic through one open lane at all times.

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!

Revegetation Work to begin at New Crystal Springs Bypass Tunnel site in San Mateo

Beginning on or around Thursday, December 1st, work crews will begin weeding and grading the South Shaft site area off of Polhemus Road in San Mateo.

The work is part of the final revegetation/relandscaping work for the New Crystal Springs Bypass Tunnel project, which was completed this past summer.

During the week of December 5th, crews will spray a hydroseed mixture on the site. Hydroseed is a mixture of seeds and nutrients, often green or blue in color (see example in photo) that will germinate into grasses this winter and spring.

Some equipment, including work trucks, grading machinery and a water truck, will be on site for the next several weeks.

Crews have been asked to maintain dust control and water down the site often. They have also been asked to minimize noise and keep the roadway near the entrance clean and free of mud and debris.

Work hours will be Monday - Friday from 7am to 5pm with some Saturday work possible beginning at 9am.

Please contact Amy Sinclair at 415-551-4659 or asinclair@sfwater.org with any concerns or questions. After hours and weekends, please call 866-973-1476.
