COUNTY OF SUFFOLK STEVEN BELLONE COUNTY EXECUTIVE DEPARTMENT OF ECONOMIC DEVELOPMENT AND PLANNING DIVISION OF PLANNING AND ENVIRONMENT COUNCIL ON ENVIRONMENTAL QUALITY TOM GULBRANSEN CHAIRPERSON CEQ MEMORANDUM TO: Interested Parties/Involved Agencies FROM: John Corral, Environmental Projects Coordinator JC DATE: October 15, 2020 RE: Proposed Suffolk County Southwest Sewer District No. 3 Extension Project – Central Islip, Town of Islip ___________________________________________________________________________________ Suffolk County has begun the environmental review process for the Proposed Construction of the Suffolk County Southwest Sewer District No. 3 Extension – Central Islip, Town of Islip. In accordance with Title 6 NYCRR Part 617.6(a) and (b) the County of Suffolk has preliminarily reviewed this project and determined that it constitutes an Unlisted Action. As an Involved/Interested Agency, you are hereby notified that Suffolk County intends to assume Lead Agency status and comply with all necessary SEQRA requirements. Any objections to the County’s position should be received within thirty days of the date of this mailing. Enclosed is an Environmental Assessment Form for the above referenced County project which has been submitted to the Council on Environmental Quality (CEQ) for review. Pursuant to Title 6 NYCRR Part 617 and Chapter 450 of the Suffolk County Code, the CEQ must recommend a SEQRA classification for the action and determine whether it may have a significant adverse impact on the environment which would require the preparation of a Draft Environmental Impact Statement (DEIS). The Council would like to know any comments you may have regarding this proposal and whether you think a DEIS or a determination of non-significance is warranted. This project will be discussed at the October 15, 2020 CEQ meeting. If you are unable to attend the meeting to present your views, please forward any comments you may have to this office prior to the date of the meeting.

This would be accomplished by extending the sewer service area of Suffolk County Sewer District #3 (SCSD #3) from its current northern boundary at Smith Street to a new boundary less than a mile north at East/West Suffolk Avenue. Specifically, the Proposed Project involves the installation of a new 24-inch diameter gravity sewer main on Carleton Avenue for approximately one mile, from Suffolk Avenue to the existing 15-inch diameter gravity main located 500 feet south of the Sunburst Boulevard/Bishop McGann Drive intersection, which is within the existing boundary of SCSD #3 (Figure 2). 1.2 Project Location The Hamlet of Central Islip is located in the Town of Islip, Suffolk County (Figure 1). The proposed extension of SCSD #3 (Project Site) is generally bounded by the properties fronting Carleton Avenue between East/West Suffolk Avenue to the north and Smith Street to the south (Figure 3). The Project Site is a roughly 2/3-mile corridor, comprised of a mix of land uses including commercial, institutional, industrial, and residential. Uses along the adjacent side streets of the corridor are primarily single-family residential homes (Figure 4). The Project Site is mapped with the following zoning districts: Residential - Residence A (A), Residence B (B); Commercial - Business District (BD), Business 1 (BUS1), Business 3 (BUS3); and Industrial: Industrial 1 (IND1). The business districts are generally mapped along Carleton Avenue; the industrial district is generally mapped in the northwest corner of the Project Site (Figure 5).
