This week I’d like to recognize critical, often unsung members of our City team who perform a vital service during rainstorms: the Utilities Department crews that pump storm water and operate the tide valves on Balboa Island and the Peninsula.

The valves, which were built in the 1970s to replace a system from the early 1900s, are necessary to prevent flooding in low-lying areas. They are manually operated, and need to be closed during high tides to prevent seawater from flooding the streets. Once the tide recedes, crews reopen the valves — nearly 90 in total — to allow water to flow from streets to the bay.
