2 INTRODUCTION This draft Scoping Document has been prepared the Town of Shawangunk Planning Board (hereafter Planning Board), as Lead Agency for the SEQRA review of the proposed HR Ventures cluster subdivision. This document is intended to serve as the foundation for the identification of all potentially significant adverse impacts pertinent to the proposed action and appropriate mitigation measures. It is also intended to eliminate consideration of any impacts that are irrelevant or non-significant. DESCRIPTION OF THE PROPOSED ACTION The project is a proposed cluster subdivision consisting of up to 22 lots and associated road system for purposes of developing 20 single-family detached dwellings. The Town Board, in its review of the cluster development, determined that the maximum yield is 20 lots. However, the applicant subsequently submitted a revised conventional layout consisting of 22 lots. A purpose of this SEQRA review is to determine the maximum yield of the project. The project would be served by individual wells and septic systems. The project is located on the west side of the Wallkill River, southwest of the hamlet of Wallkill, east of Roosa Road, and northeast of River Glen Road. The project s proposed access would be from Bruyn Turnpike and River Glen Road. The project would be located in the Town of Shawangunk, Ulster County, NY. The parcel is approximately 121 acres and identified on local tax maps as Map , Block 3, Lot 50. POTENTIAL SIGNIFICANT ENVIRONMENTAL IMPACTS As set forth in the Positive Declaration approved by the Lead Agency, the proposed action was determined to have potential significant environmental impacts, including but not limited to the following: Soil erosion and sedimentation from proposed land disturbances Alteration in existing natural drainage patterns; potential increase in stormwater runoff quantity and decline in water quality Disturbances to freshwater wetlands and on-site watercourses Potential disturbance to historic cemetery and archaeological resources Increase in traffic volumes and effect on intersection safety Demand placed on community services and facilities, including schools, fire, and recreation Alteration and elimination of natural habitat Potential impact on groundwater resources resulting from water supply demand Potential impact to groundwater from introduction of on-site septic systems Potential visibility of project from the scenic Wallkill River GENERAL SCOPING CONSIDERATIONS The applicant will prepare a site-specific Draft Environmental Impact Statement (DEIS) addressing all items described in this Scoping Document.

3 The applicant should closely examine the SEQR regulations for direction on the required content of a DEIS. Unless otherwise directed by this Scoping Document, the provisions of 6 NYCRR 617.9(b) apply to the content of the DEIS and are incorporated herein by reference. The DEIS will assemble relevant and material facts, evaluate reasonable alternatives, and be analytical but not encyclopedic. It will also be clearly and concisely written in plain language that can be easily read and understood by the public. Highly technical material will be summarized and, if it must be included in its entirety, it will be referenced in the DEIS and included in an appendix. Narrative discussions will be accompanied to the greatest extent possible by illustrative tables and graphics. All graphics will clearly identify the project area. The DEIS will group each issue identified into one Existing Setting, Impacts, and Mitigation section to permit more efficient review. Footnotes will be used as the form of citing references. A Full scale Subdivision Plan is to be included with the DEIS as an appendix and reduced copies of pertinent Subdivision Plan sheets may be included in the body of the DEIS. The plans will provide a level of engineering detail sufficient to evaluate the potential impacts of the project, and to assess the appropriateness of mitigation measures, where proposed.
