NOTICE OF PUBLIC HEARING Resolution No.44 - 2026 NOTICE IS HEREBY GIVEN that a public hearing will be held by the County Board of Legislators on May 18, 2026 at 7:30 pm., in its Legislative Chambers, 8th Floor, Michaelian Office Building, 148 Martine Avenue, White Plains, New York on the following: Property owners in Westchester County Water District No. 3, comprised of the territorial limits of the Grasslands Campus at Valhalla (“District”) are hereby notified that legislation is currently before the Westchester County Board of Legislators (“Board”) to carry out proposed Capital Project County Water District No. 3 – Eastview Pumping Station – WD305 (“WD305”) for the benefit of the District, which is a proposed increase, addition and improvement of District facilities, as more fully set forth herein and in the District Report dated December 23, 2025, as may be amended from time to time (“District Report”). The District Report is available for review from the Office of the Commissioner of the Westchester County Department of Environmental Facilities. The issuance of bonds would provide for design, construction management, and construction for installation of the Eastview Pumping Station to provide ultraviolet (“UV”) treated drinking water to the District. The new pumping station will obtain UV treated water from the County’s Eastview Distribution Chamber which currently receives its UV treated water from the New York City Department of Environmental Protection (“DEP”) Catskill-Delaware UV Water Disinfection Facility, located in Eastview. The new pumping station will be built adjacent to the Eastview Distribution Chamber and will pump UV treated water, via a new 16-inch diameter transmission main, to the district’s water storage tank. The pumping station will also provide disinfection and corrosion control treatment prior to the water leaving the station. The Department has determined that WD305 is necessary for the proper maintenance and service of District facilities and therefore is in the public interest. It will provide greater redundancy and reliability in order to ensure a continuous, uninterrupted supply of drinking water to District users in compliance with federal, state and local regulatory requirements. Based on its review, the Department has determined that WD305 is the best, most cost-effective option available to the District for this purpose. The County is currently seeking authorization of a bond act to authorize the issuance of up to County is currently seeking authorization of the issuance of up to $40,000,000 in bonds of the County to finance a portion of the cost of construction management and construction of a pumping station and transmission main or mains for the conveyance of treated water from the DEP’s UV Light Disinfection Facility at Eastview in the Town of Mount Pleasant to County District No. 3, including ancillary or related work and incidental expenses. The Department anticipates that WD305 will involve on-going operating costs above the current operating budget for additional water treatment, power consumption, and regular equipment maintenance. The anticipated additional cost is $120,000 annually. The Department has calculated that the issuance of $40,000,000 in bonds of the County for WD305 equates to an estimated annual debt payment of $2,729,087.50. Added to the above mentioned additional operating costs gives a total annual cost of $2,849,087.50 which, if distributed over the 259,920 taxable parcels in the County, equates to an estimated average increase in tax assessment of $10.96 per parcel.
