I can just imagine what it looks like now. Back when I was there (left in 1980) they were practically giving land away. I looked at some land for sale over in Mandarin. It was pine trees, scrub oaks, palmetto and sand. They tell me now all of that area is very very expensive. Between Jax and St. Augustine was mostly undeveloped especially down US-1. Missed opportunities abound.
That photo of the cracks in the arch way. That is just going to get worse too. People want to build homes on the beach and I admit it is tempting but Ive seen so many with serious problems. Lots of snowbirds buy down here to find out later it isn’t for the faint of heart. I did a lot of work on Penscola Beach, Perdido Key after hurricane Ivan. Mostly slabs or only pilings left standing. Some of the homes left were just junk not only from the hurricanes but from that constant exposure to the sand, salt, rain and sun. It works on a house something fierce.
Are you doing much EIFS over your way? Only get it here occasionally. Always wrong with many problems. Ive seen one house it was done right since the training we did.
