Three members of the East Hampton Town Board agreed at a work session on Tuesday to move forward on “parallel tracks” to implement both long-term and short-term recommendations made by a town committee on coastal erosion. Town Councilwoman Sylvia Overby and Councilmen Dominick Stanzione and Peter Van Scoyoc outlined the steps to be taken in the absence of Town Supervisor Bill Wilkinson and Councilwoman Theresa Quigley, who did not attend.
