Lower Crystal Springs Dam Upgrades Complete: Skyline Bridge Replacement to Start Next Year

With the WSIP upgrades to the Lower Crystal Springs Dam now complete, San Mateo County will be moving forward on plans to replace the Skyline Bridge, originally built on top of the dam and demolished in 2011 for reasons of seismic safety. Construction of the new bridge is currently expected to begin in the spring or summer of 2015 and finish in early or mid 2017.  For updates, visit the County website at publicworks.smcgov.org.  

Harry Tracy Night Work Update

Dear Neighbors:

We greatly appreciate your patience as we continue work on the crucial upgrades to the Harry Tracy Water Treatment Plant. Swing shift work until 3 a.m. will need to continue at the plant in order to complete this project and not hinder the ongoing operations of the plant to provide drinking water to our customers.

However, we are making changes to minimize noise. 
1) The project team has rescheduled certain noise-generating construction activities from the night shift to the day shift in order to minimize noise.
2) Outdoor work during the swing shift will end at approximately 12 a.m. Monday to Friday, and 9 p.m. Saturday. There is no swing shift Sunday evenings.
3) The Project has requested and received permission from Cal-OSHA to muffle the back-up alarms on equipment so they will only be heard in the immediate area.
4) Additionally, the contractor has been instructed to double its efforts to cover work areas surrounding noisy activities to attenuate the noise from travelling throughout the community.  

Because of the nature of the work, crews may work 24 hours a day inside the new 11 million gallon Treated Water Reservoir. It is unlikely that this will be audible outside the plant boundaries.

Noise monitors will take readings every night on both the San Bruno and Millbrae sides of the plant to ensure compliance. Night work is expected periodically through December 2014. The project is 90% complete and on schedule to wrap up major construction at the end of this year.

Thank you again for your continued patience and support. These badly needed upgrades will help ensure a reliable water supply to our customers.

Please call us at (866) 973-1476 with any questions or concerns.
