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 email@example.com with any concerns or questions. After hours and weekends, please call 866-973-1476.
