At a meeting on Friday, for the second time, the East Hampton Village Zoning Board of Appeals granted Howard Schultz, the president of Starbucks, and his wife, Sheri Kersch Schultz, an interior designer, a coastal erosion hazard permit and a variance to allow the construction of a deck and a 2,521-square-foot addition at the first floor and basement levels of their waterfront house on Gracie Lane. The property is just over four acres.
