This a really cool tool. The above site is called the Coastal Emergency Risk Assessment and these folks predict storm surge. OK, I can get that on the news. BUT it also has historic storm surges for many storms.
This gives the water height above Mean Sea Level. The Mean Sea Level at the Lake Worth Pier is ABOUT -1′ by the 1988 NAVD datum. So if your home is at +7′ NAVD then you would need and 8′ storm surge by these metrics to get your floor wet. FYI, the Mean High Water at the pier is +0.37′ and we have hurricanes at the time of the year that we have the astronomical “king” tides. This results in the actual water level, at high tide, being more like +2′ NAVD. If the prediction is for a 5′ storm surge and it’s occurring at a king high tide the water is lapping at the slab of a +7′ floor level house.
