In an unfortunate reversal, the East Hampton Town Zoning Board of Appeals has given permission for Lazy Point property owners to build a sea wall in a zone where none are allowed under town law. What makes this bad decision all the worse is that the same board had denied an essentially identical request earlier this year. Complicating the situation was that the State Department of Environmental Conservation handed out approval for the sea wall in direct, but so far unexplained, violation of an agreement with the town that is supposed to make state agencies follow East Hampton’s rules.
