Background and Document Organization This is a Final Environmental Impact Statement (FEIS) issued by the Town of Windham Planning Board, the Lead Agency, in accordance with Article 8 of the Environmental Conservation Law (ECL) also known as the State Environmental Quality Review Act (SEQRA) and implementing regulations (6 NYCRR Part 617). The proposed action that is the subject of this FEIS is the construction and operation of a residential sporting club known as the Windham Mountain Sporting Club in the Town of Windham, Greene County, New York. This FEIS consists of two parts. The first part of this document is the Draft Environmental Impact Statement (DEIS) and accompanying appendices and drawings/plans that were accepted as complete by the Windham Planning Board as Lead Agency on March 1, 2012. This FEIS incorporates the DEIS by reference. The second part is this FEIS document that addresses the issues raised during the DEIS public comment period as well as comment letters submitted to the Lead Agency after the close of the public comment period. Together the DEIS and FEIS constitute the Environmental Impact Statement (EIS). The SEQRA process is structured to allow examination of all relevant environmental issues by technical experts, agencies, and the public in order that the lead agency and other involved agencies may make reasoned and informed decisions. This FEIS has been prepared by the Lead Agency, with assistance from the Lead Agency’s technical consultants, the Applicant, and their consultants in order to carefully analyze comments and take a hard look at potential environmental impacts and proposed measures to mitigate such impacts. The FEIS provides additional information regarding existing environmental conditions, potential environmental impacts, and measures proposed to mitigate the potential impacts that were identified. The following section of this document, Errata, presents summaries of some of the topics for which revised information is provided in the FEIS, including: 1. Steep Slope Disturbance and Sediment and Erosion Control 2. Stormwater Management 3. Hydrogeology 4. Blasting/Noise 5. ARB Guidelines 6. Visual Impact Assessment 7. Recreation Demands 8.
