David Kronman and Curtis Sachs, representing Cape Advisors, which has acquired the Baron’s Cove property on Water Street, moved closer at Tuesday night’s meeting of the Sag Harbor Village Planning Board to special exception approval of a plan to construct an 87-seat restaurant and 8-seat bar as an “accessory use to a resort motel.” The men were prepared and assisted by Richard Warren of InterScience Associates in responding to a letter from Timothy Platt, the village’s building inspector. The property is zoned for resort motel use.
