Central Beach tidal flooding and backflow preventers
Summary
The September king tide plus Nor'easter pushed a record 2.77-foot tide over parts of the Broadwalk, flooding streets and businesses near Michigan Street. Board members asked staff to develop a pilot using knee-wall closures or removable gates at the lowest-elevation stretch, and debated dunes versus hardscape. An expert confirmed today's king tide levels become the normal sea level by 2050.

City Commission (Regular) - Sep 16, 2026
Two resolutions would lock in a $2.97 million state Resilient Florida grant plus matching city GO bond funds and a construction agreement with FDOT for tidal flooding improvements. This is about keeping streets and shorelines protected from sea-level-rise flooding.

Community Redevelopment Agency (Regular) - Mar 4, 2026
King tides keep flooding the east-west streets between Hollywood Boulevard and Sherman Street. Installing ~30 WAPROS backflow preventers for about $1.3 million is the fast fix; raising the six lowest streets would cost $6.4 million and needs more study.
Community Redevelopment Agency (Regular) - Jan 21, 2026
Bob Glickman pressed again on flooding: street-end dips at A1A, broken flapgates on the Intracoastal, and a blocked FDOT outfall at the Trafalgar condos causing flooding. FDOT's district secretary may appear at the March or April meeting.
