Those new building standards could affect future construction in several areas along the eastern shore of Pinellas County, such as portions of Snell Isle. That zone means new buildings in some areas could become much more expensive to construct In practical terms, it means new construction on those properties must be built to more stringent standards than in areas not expected to see waves hitting buildings.Ģ. Anything between that line and the “VE” zone is now called something new - a coastal “AE” zone. So FEMA drew a line on the new flood maps to show where those smaller waves are expected to start. New data shows that waves as small as 1.5 feet also cause significant damage. But that assumed the waves would be a minimum of 3 feet tall. In prior years, “VE” zones reflected areas where buildings were considered susceptible to wave damage from storm surge. The zones range from low-risk (“X”) to high-risk (“A” and “V”). The new map expands areas at risk from wavesĬounties are divided into flood zones based on how severe flooding could be. Scroll down to the bottom for an interactive map of the changes.ġ.
Here are five major changes between the old and new Pinellas County maps. “Some areas’ flood elevations went up, and some areas’ flood elevations went down.” “What we saw (in Pinellas County) is very similar to what we’re seeing along the coast of Florida,” Mark Vieira, senior engineer at FEMA. Pasco County held open houses for the public to view maps and ask questions last year, while Hernando County did the same in January. It’s a process playing out throughout Florida, with residents in Hillsborough County recently getting a first look at flood map adjustments there.
