N.Y. General Municipal Law § 239-n (referral of subdivision plats to the county planning agency)
Under General Municipal Law § 239-n, a municipality in Westchester County must refer applications for preliminary and/or final subdivision plat approval to the Westchester County Planning Board before final action where the property lies within 500 feet of a municipal boundary, an existing or proposed county or state park or recreation area, the right-of-way of an existing or proposed county or state parkway/thruway/expressway/road/highway, a county-owned stream or drainage channel, county- or state-owned land on which a public building or institution sits, or a farm operation in an agricultural district. The County Planning Board reviews for inter-community and county-wide impacts and reports a recommendation (approval, modification, or disapproval) to the local approving authority, which may act contrary to a recommendation of modification or disapproval only by a majority-plus-one supermajority vote.
