Assemblymember Didi Barrett has requested Pat Grattan, Chairman of the Columbia County Board of Supervisors, to hold off on plans to expand the Columbia County Airport through eminent domain until questions raised by the public regarding the project’s need have been fully addressed by the board. In a letter to the chairman, dated Thurs., Oct. 10, the Hudson Democrat wrote, “The residents of Columbia County have a right to understand both the need for and the full economic implications of the proposed airport expansion. There are still too many questions that remain unanswered.” The letter was released by Barrett's office, Thursday. The full board Wed., Oct. 9, rejected a resolution to table plans to expand the county airport safety zone through eminent domain. The acquisition process has been estimated to cost anywhere from $8 million to $13 million.
