Since the 70s and 80s, the pilings might be 40 or 50 feet down so they will be there but the sand around the building could be gone. The trouble with the sand being gone is the pilings are using skin friction to hold the buildings down in a wind event. Without the sand, no skin friction, and the wind pushes the building over. Not as common with concrete tilt up or precast, but with pre-engineered metal buildings, which are built as light as possible, you need that skin friction, or if shallow foundations they need to be massive enough to keep the wind from blowing the building over or away! That is why the pilings are down 40 or 50 feet. People who move to Florida and settle right on the water would do well to take a lesson from a couple of generations of old Floridians. You don't see them build right on the beach!!! I am about 5 miles from the beach, behind 2 miles of mangroves. The surge from that direction will be blunted by nature. I have US41 and I75 to the east that will stop sheet flow from the everglades. It is a very effective flood control dam. Mangroves are good for a LOT of reasons, one is that it will keep the sand in place. It also breaks up a surge tide, provides habitat for all kinds of wildlife and helps with global warming. I like the mangroves here because they are protected and nobody is going to build anything else in the bay. Why are they called man"groves? |

Why are they called man"groves? Big roots they stick everywhere they can But why do they call them "man" groves. I can see citrus groves. But why man groves Because they stick their roots wherever they can, didn't you get it?? |
