Fishers Island Country Club to 24,741 sq. ft., including the addition of 28 parking stalls and a new sanitary system on 12.3 acres in the R-120 Zoning District, Fishers Island. The proposed action has been reviewed to Chapter 268, Waterfront Consistency Review of the Town of Southold Town Code and the Local Waterfront Revitalization Program (LWRP) Policy Standards. Based upon the information provided on the LWRP Consistency Assessment Form submitted to this department, the proposed action is recommended as CONSISTENT with the LWRP provided the following is considered: Policy 2.2. Protect and preserve archaeological resources The parcel is included within the archeo-sensitive mapped area (MAPINFO GIS-Archeo- sensitive layer). The site is previously disturbed and a cultural resources survey is not recommended. Groundwater Quality The following is recommended to further policies 5. Protect and improve water quality and supply in the Town of Southold and 6. Protect and restore the quality and function of the Town of Southold ecosystem: Fishers Island water supply is dependent upon a sole source aquifer and 22 miles of water mains, an equalization reservoir, a surface water treatment plant, a groundwater treatment facility, a well field and three surface water reservoirs: Barlow Pond, Middle Farm Pond and Treasure Pond. The numerous ponds on Fishers Island serve as the primary catchment and recharge areas for the islands aquifer. The hydrology of Fishers Island differs substantially from other portions of the Town of Southold. Due to its hilly topography, most of the precipitation that falls on Fishers Island flows to one of the numerous freshwater ponds or directly to the coastal shoreline. According to the Hydrogeologic Report Conducted on Fishers Island, New York (Groundwater, Inc., April 1990), groundwater recharge on Fishers Island is estimated to be approximately 709 million gallons per year. The water supply, treatment, distribution and storage facilities for Fishers Island are owned and operated by the Fishers Island Waterworks, a subsidiary of the Fishers Island Development Corporation (FIDCO). The FIDCO water supply system, originally constructed in the early 1900's, services approximately 624 customers. It is my understanding that this area is not currently in the watershed contributing to the public water supply. However, future use of the groundwater is unknown and therefore, protection of the resource is recommended. The proposed action would add an additional 1500 gallons per day (gpd) over the existing 6,710 gpd of water use/sanitary flow to total 8,250 gpd. Disposal is proposed via the expansion of a conventional sanitary wastewater system. In recent years, there is concern of groundwater impairment from nitrogen, pharmaceuticals, personal care products and volatile organic compounds and public health. Surface waters are also impacted from nitrogen influence leading to algal blooms, hypoxic conditions and fish kills. Lakes and,ponds are susceptible to eutrophication conditions as a result of excessive nitrogen (depending upon groundwater directional flow). These concerns have led the Suffolk County Department of Health Services to develop innovative and alternative sanitary systems that are capable of treating total N effluent equal to or greater than 60 percent over conventional systems levels. However, due to the possible seasonal fluctuations a natural, nitrogen fixation system may be more beneficial than a mechanical innovative or alternative sanitary treatment. This type of treatment does not rely on the continuous effluent flows for nitrogen fixation processes to work. Additionally, golf courses can use significant amounts of fertilizers and, in some,instances, pesticides and herbicides. To mitigate impacts to surface waters and groundwater, the following BMP's are recommended: a. Require the use of native, drought-tolerant plants in landscaping. b. Prohibit the application of fertilizer products containing nitrogen, phosphorus, or potassium between November 1St and April 1St c. Apply only the minimum amount of slow-release and organic fertilizer needed to sustain healthy turf on golf courses, and that fertilizer application rates shall be limited to 3 lbs. of nitrogen/1000 sq. ft. per year, over the golf course as a whole (This is consistent with the Organic Maintenance Plan adopted via Suffolk County Resolution No. 608-1998.) Pursuant to Chapter 268, the Board shall consider this recommendation in preparing its written determination regarding the consistency of the proposed action. Cc: Brian Cummings, Planner
