This chapter, or any part thereof, may be amended, supplemented or repealed, from time to time, by the Town Board, pursuant to statute, on its own motion or upon recommendation by the Planning Board. Every proposed amendment shall be referred by the Town Board to the Planning Board for a report, which shall be rendered within 45 days of such referral. Failure by the Planning Board to render such report within the time specified shall be considered to be tantamount to a recommendation for approval. Nothing herein shall be construed to prevent the Town Board from acting on a proposed amendment prior to receipt of the Planning Board's recommendation as specified in this article; provided, however, that the proposed amendment shall be adopted by a super-majority vote (majority plus one) of the full Town Board membership.
