In accordance with the policy and procedures provided for by Article 12-B, §§ 239-1 and 239-m, of the General Municipal Law, any proposed interpretation or variance affecting real property within 500 feet of the boundary of the Village of Nassau or from the boundary of any existing or proposed county or state park or other recreational area, or from the right-of-way of any existing or proposed county or state parkway, thruway, expressway, road or 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 state-owned land on which a public building or institution is situated, shall be referred to the Rensselaer County Planning Board at least five days before any scheduled hearing. The referral to the County shall include a full statement of the proposed action. The term "proposed" shall be deemed to include only those recreational areas, parkways, thruways, expressways, roads or highways which are shown on a County Plan of Rensselaer County adopted pursuant to § 239-d, Subdivision 2, of the General Municipal Law or adopted as an Official Map of Rensselaer County pursuant to § 239-g of the General Municipal Law. If the Rensselaer County Planning Board fails to report within 30 days after receipt of a full statement of such referred material, the Board of Appeals may act without such report. If the Rensselaer County Planning Board disapproves the proposal or recommends modifications thereof, the Board of Appeals shall not act contrary to such disapproval or recommendation except by a vote of a majority plus one of all the members thereof and after the adoption of a resolution setting forth the reasons for the contrary action. The Board shall file a report of its final action taken with the County Planning Board within 30 days after its decision has been made.
