The East Hampton Town Board passed a somewhat rushed resolution Tuesday, allowing the town to spend just over $500,000 to acquire five pieces of land, including one 7.7-acre tract, from Suffolk County. Four of the five parcels would be used for affordable housing and one unbuildable lot in Montauk would go to open space. Supervisor Kathee Burke-Gonzalez explained that the county had set tomorrow as a deadline to authorize the expenditure.
