Geotechnical Investigations Set for July 16-17, Most in Redwood Shores

Consultants for Silicon Valley Clean Water on Wednesday and Thursday, July 16 and July 17, will be conducting preliminary geotechnical investigations in the locations described and shown below.

The work, called cone penetrometer tests, involves a truck parked on the pavement for about an hour, sometime between 7 am and 5 pm. In some locations if a lane is blocked, traffic control will be provided to direct traffic around the truck.

The truck has equipment that will push a rod down into the ground to depths of up to 120 feet in order to gather information about the ground so that engineers can confirm if a deep tunnel is feasible.

The geotechnical investigation is part of investigating the feasibility of replacing SVCW pipelines without surface disruption through Redwood Shores.

The six locations are:
C-1 Shearwater Parkway between Breakwater Drive and Mindano Drive.
C-2 Redwood City Reservoir near Avocet Drive.
C-3 Shell Parkway between Marine Parkway and Davit Lane.
C-5 End of Spar Drive.
C-7 Twin Dolphin Drive between Shoreline Drive and Lagoon Drive.
C-10 off of Whipple Avenue near E. Bayshore Road.
