Abstract
The Hollywood Lakes area in Hollywood, Florida, and Las Olas Boulevard area of Fort Lauderdale, Florida experience nuisance flooding, or “sunny day†flooding, during extreme high tides. This flooding causes damage to residential and commercial properties and to critical municipal infrastructure. The influences of rising sea levels, extreme rainfall events, and coastal storm surge compound these flooding events, Hollywood and Fort Lauderdale form part of eastern Broward County, a densely populated area in South Florida bordered on the east by the Atlantic Ocean and on the west by the Everglades. Numerous drainage canals connect the Everglades wetlands and the coastal urban area, with typical elevations of 5-10 ft-NAVD. Porous limestone groundwater substrate further contributes to complex local hydrology.

The Flood Risk Management (FRM) Study selected four tropical storm events from the Federal Emergency Management Agency (FEMA) Region IV study suite to produce a range of storm characteristics and inundation patterns
As part of the FRM Study, Taylor Engineering, Inc. is conducting 2D hydrodynamic and wave modeling to evaluate the contributions of storm surge and seawall elevations on the nuisance flooding
