The Board shall refer to the Dutchess County Planning Board for its recommendation all matters within the provisions of Article 12B, §§ 239-l and m, of the General Municipal Law, which include real property lying within 500 feet of the boundary of any city, village or Town or from the boundary of any existing or proposed county or state park or other recreation area or from the right-of-way of any existing or proposed county or state parkway, thruway, expressway, road, highway or from the existing or proposed right-of-way of any stream or drainage channel owned by the county or for which the county has established channel lines or from the existing or proposed boundary of any county- or state-owned land on which a public building or institution is situated or from the boundary of a farm operation within an agricultural district, as defined by Article 25-AA of the Agricultural and Markets Law. The Dutchess County Planning Board shall render its decision within 30 calendar days of referral or within an extended period if agreed upon by the Town approving agency and County Planning Board. If the Dutchess County Planning Board fails to report within such period of 30 days or such longer period as has been agreed upon, the Town approving agency may act without such report. If the Dutchess County Planning Board recommends disapproval of the proposal or recommends modification thereof, the Town approving agency shall not act contrary to such recommendations except by a vote of a majority plus one of the full membership thereof and after the adoption of a resolution fully setting forth the reasons for such contrary action. If the Town approving agency takes contrary action, within seven days after taking such action the Town approving agency shall file a report of such action with the County Planning Board.
