The East Hampton Town Zoning Board of Appeals agreed with the town Planning Department last month that a detailed and lengthy environmental review is necessary for a proposal to build a 108-foot stone revetment, 83-foot PVC retaining wall, and new house at 117 Bay View Avenue on Napeague. This despite accusations of complicity between the board and the Planning Department from Brian Matthews, the attorney for Nicholas Grecco, who owns the parcel.
