The financial affairs of the East Hampton Town Trustees, who own much of the common lands and waterways in town on behalf of the public, were front and center in August, as the town looks ahead to a new fiscal year in January. The East Hampton Town Board allots about half the trustees’ annual budget each year — it was $251,456 this year — while other revenue comes from fees, including those for mooring or docking in waters under their jurisdiction, and from leases of trustee land at Lazy Point in Amagansett.
