Quietly late last month the East Hampton Town Trustees went to court to seek to overturn a decision by the East Hampton Town Zoning Board of Appeals giving a Lazy Point couple permission to build a sea wall, or revetment. Though as of this writing we had not seen the suit itself, presumably, the trustees are challenging the Z.B.A. ruling on two points: that required trustee approval was not obtained and that the revetment would violate the town’s own coastal erosion law.
