Dredging at the Lagoon Intake Structure (CIP 301-629)


Dredging (resized)

For more information regarding this Capital Improvement Project, please contact Allan Shu, Senior Civil Engineer, in the Public Works Department at (650) 286-3271.

Project Description:

The water level in the Foster City Lagoon is regulated by allowing water in through the intake structure by Sea Cloud Park and pumping water out into the San Francisco Bay, by the City's Corporation Yard. Over the years, sedimentation has built-up on the Belmont Slough side of the intake structure, resulting in limited water flow into the lagoon. The sedimentation in front of the lagoon intake structure impedes water from flowing into the lagoon except during periods of high tides. In addition, at times, sediment also blocks the Bay Level Transducer, producing inaccurate water level readings.

The key objectives of the project include the following:
  • Restoring the west intake structure to its original, intended function of transmitting water from the Belmont Slough into the lagoon; and
  • Safely and efficiently removing and disposing of sediment material currently obstructing the west intake structure.
The project consists of an Initial Study/Mitigated Negative Declaration that analyzes the environmental impacts associated with dredging and disposing of sediment material currently obstructing the west intake structure and limiting water flow into the lagoon and incorporates project mitigation measures to eliminate any potential significant impacts.

Project Status:

The contract is anticipated to be awarded to Salt River Corp. on May 15, 2017.
