DISCUSSION:
The tide vault at 19th Street serves as the terminus for the storm drain line that drains
19th Street and Balboa Boulevard from 19th Street to 16th Street. The significant depth of
the outlet pipe draining into the Bay requires a tide gate. Without the gate, the low lying
areas of 19th Street and Balboa Boulevard would flood during high tide events. During
combination high tide and rain events, the system is quickly overwhelmed and Municipal
Operations field crews stage pumps at the end of 19 h Street to prevent street flooding.
The project proposes to remove the existing electric tide valve and install a new passive
tide valve. A similar valve operates at Pearl Avenue and has been successful in
reducing the need for human intervention during high tide events. In addition, the project
will install a submersible pump in the tide vault. The pump will operate according to the
level of water in the vault and drain the storm drain system on occasions where rain and
high tides make flooding possible. The pump will eliminate the need to pull portable
pumps to the site during rain and tide events. The pump control panel is being installed
in a fashion that allows for future integration into the City's Supervisory Control and
Data Acquisition ( SCADA) system. The SCADA system permits an operator to monitor
the pump from a central terminal or via handheld electronics.
At 9:00 A.M. on May 9, 2012, the City Clerk opened and read the following bids for this
project:
