The highest elevation is estimated at 46 ft, while the average elevation is 0 feet. A floodplain map delineates the area that can be expected to flood, on average, once every 200 years. Effect of sea level rise or sea level change. A majority of the City of Fort Lauderdale's residents live in or close to a Special Flood Hazard Area (SFHA), where flooding may occur.This means property is in or near the SFHA, as mapped by the Federal Emergency Management Agency (FEMA), and is prone to flooding. Elevation values from maps using different vertical datums (e.g., NGVD 29, NAVD 88, MLLW, and MHHW) are not directly comparable because they are based on different frameworks and starting (or zero) points. The poster child for sea level rise, the Maldives was once a vast island during the last glacial maximum, when sea levels were at their lowest ebb. Even if global warming were to stop today, sea level would continue to rise. Data depicting the predicted levels of sea level rise was developed and provided by NOAA Coastal Services Center in Charleston, SC using 20 LiDAR data. Rate of sea-level rise since 1993 from NASA's Goddard Space Flight Center. Here are the places most at risk, according to an. Linn's representations of seven cities in the United States and Canada portray how they would look if all the world's ice caps melted and sea levels rose more than 200 feet. Detailed maps depict the current and projected conditions of the region according to sea level in feet. The data and maps in this tool illustrate the scale of potential flooding, not the exact location, and do not account for erosion, subsidence, or future construction.
