My understanding is the 20 meter wide Federal Zone basically begins at the high tide line and extends back to the front boundary of beach-front properties. As beach erosion occurs over time, periodically the Feds resurvey the Federal Zone boundaries to follow the high tide line. If the Federal Zone is moved back into a beach front property the annual property taxes of that property will triple. The way to prevent this from happening is to apply for and secure a Federal Zone Concession which will lock the Federal Zone boundaries in front of your property as long as you build a sea wall making a reasonable attempt to prevent beach erosion from occurring. And stay current with your annual property taxes and Fed Zone Concession fees. I heard there were areas in LC where over the years the Federal Zone was resurveyed and moved back to a point where it was getting close to the second row properties.Don't know about moving the Federal zone. Two of the homes are out in section 5 and 9, the tip of the peninsula. Also heard a rumor that Tessoro has significant structural problems.
Found one of those horned rattleshakes in my beach shelter we leave up at Santo Tomas... another under the kayak ( we leave on beach above tide line..in ten years never lost one)Not to mention the snakes. Damn things scare the crap out of us when they dart out in front of you.
