Public review for proposed multifamily development in floodplain in Tarrytown.

Final Notice and Public Review of a Proposed Activity in a Federal Flood Risk Management Standard Designated Floodplain To: All interested Agencies, Groups, and Individuals This is to give notice that HUD under 24 CFR Part 50 has conducted an evaluation as required by Executive Order 11988, in accordance with HUD regulations at 24 CFR 55.20 in Subpart C Procedures for Making Determinations on Floodplain Management and Wetlands Protection. The proposed activity is funded under U.S. Department of Housing & Urban Development (HUD) Community Development Block Grant ? Disaster Recovery (CDBG-DR) funds and RAD/Section 18 blend program (RAD PIC Number NY013000001B). The proposed multifamily development project is located at 1 ? 99 Franklin Court in Tarrytown, Westchester County, New York and is located in the Federal Flood Risk Management Standard (FFRMS) floodplain. The existing 7.4-acre development was constructed in 1952 and consists of 70 dwelling units housed in 14 two-story buildings and a single-story leasing office/community room and maintenance shop. Tarrytown Municipal Housing Authority (TMHA) is seeking demolition/disposition approval due to the obsolescent physical condition of the housing development. The redevelopment of the Franklin Courts property would include the construction of two (2) four-story multifamily residential buildings of 33 units each with parking in the lower level of the buildings, two buildings with twelve (12) attached two-story townhouse-style units each, a clubhouse building, a stormwater management practice (SMP) area, and open space for residents. The new development would provide 90 total units. The existing units will be replaced by 70 units financed with Project-based Vouchers. On or about March 17, 2026, the New York State Homes & Community Renewal (HCR), through the New York State Housing Trust Fund Corporation (HTFC), will submit a request to U.S. Department of Housing and Urban Development (HUD) for the release of $3,000,000 in Community Development Block Grant ? Disaster Recovery (CDBG-DR) funds and for the release of 70 Project-Based Vouchers via RAD and Section 18 programs. There will be twenty (20) additional tax credit units as well. The extent of the FFRMS floodplain (elevation 11 feet) was determined using the freeboard value approach by adding two feet to the Base Flood Elevation of 9 feet indicated on the Preliminary FIRM Panel 36119C0253G. The Preliminary FEMA FIRM Panel provides the latest and most conservative available flood elevation data for the property. A total of 5.1 acres of the property has been determined to be located in the preliminary 100-year floodplain and a total of 5.9 acres of the property has been determined to be located in the FFRMS floodplain, inclusive of the area of 100-year preliminary floodplain. No 100-year floodplain occurs on the property based on current effective mapping. The entire extent of the preliminary flood plain will be impacted as part of the Remedial Actions of the Brownfield Cleanup. A total of 3.1 acres of FFRMS floodplain, inclusive of 2.4 acres of preliminary 100-year floodplain, would be impacted to construct the development as proposed. Due to the fact that the property has already been developed and is located in an urban area, the FFRMS floodplain on the property minimally functions to attenuate stormwater and control erosion. No rare or unique recreational, educational, scientific, historic, or cultural resource values are known to occur on the property. HUD has considered the following alternatives and mitigation measures to minimize adverse impacts and to restore and preserve natural and beneficial functions and intrinsic values of the existing floodplain/wetland: (1) Under the no-action alternative, the multifamily housing development would not be demolished, and the quality of the current housing would continue to deteriorate. The environmental impacts associated with the proposed project would not occur under the No Action Alternative. The No Action Alternative would not preclude the development from being demolished and/or redeveloped at a future date without affordable housing opportunity. (2) The development team originally considered elevating the entire site with fill material and locating buildings along the perimeter of the western edge of the site. This alternative was rejected to reduce floodplain impacts by locating the development areas to the far east of the property furthest away from the area of floodplain and leaving a large open space park area for residents in the 100-year floodplain area. (3) As proposed, a total of 6,400 CY of fill material would be added to the subject property to elevate buildings to FFRMS and CRRA elevation standards. The proposed Site Plan nestles the total developed area on the eastern area of the site, furthest from the Floodplain. The clubhouse would be elevated to the FFRMS elevation of 11 feet. All multifamily units would be elevated to 14 feet, five feet above the Base Flood Elevation. In order to minimize disruption to the residences the project has been designed to maximize the number of residents who will remain onsite during the proposed construction. Pursuant to Section 18, a public housing authority must provide relocation assistance (e.g., the payment of actual and reasonable relocation expenses) to residential tenants. An Evacuation Plan out of the preliminary FFRMS floodplain will be distributed to residents. Renter Notifications will be provided to residents for signature to disclose the area of floodplain on the property and indicate that flood insurance is available for purchase in the community for their personal property, although it is not provided or required by standard rental policies. Based on being able to maintain as many residents onsite as possible during construction there is sufficient land area to provide temporary sediment basins to control stormwater during construction. Diversion swales and collection systems are provided to capture stormwater during all phases of construction. A temporary drain inlet is proposed at the end of the diversion swale and check dams have been added to aid in erosion control. A proposed bioretention filter is being installed primarily for water quality treatment. Based on the separation to the bottom of practice, an impermeable liner has been added to the bottom and sides of the drainage layer. Additionally, a the Bioretention Filter Outlet Structure is proposed to clean collected stormwater; however, it is not anticipated that groundwater will be encountered. All work would be completed in compliance with state and local floodplain/wetland protection procedures. HUD has reevaluated alternatives to building in the floodplain and has determined that it has no practicable alternative to floodplain development. Environmental files documenting compliance with Executive Order 11988 are available for public inspection, review, and copying upon request at the times and location delineated in the last two paragraphs of this notice for receipt of comments. There are three primary purposes for this notice. First, people who may be affected by activities in floodplains and those who have an interest in the protection of the natural environment should be given an opportunity to express their concerns and provide information about these areas. Second, an adequate public notice program can be an important public educational tool. The dissemination of information and request for public comments about floodplains can facilitate and enhance Federal efforts to reduce the risks and impacts associated with the occupancy and modification of these special areas. Third, as a matter of fairness, when the Federal government determines it will participate in actions taking place in floodplain, it must inform those who may be put at greater or continued risk. As the proposed demolition and RAD project vouchers would be administered by HUD and the development would also be partially funded by CDBG-DR funds administered by New York State HCR, public comments should be received by both HUD and the HCR at the following locations or by emailing the following contacts: State of New York HCR: Additional project information can be obtained from HCR by emailing environmental.comments@hcr.ny.gov or at: https://hcr.ny.gov/hcr-environmental-review. Public comments can also be provided to Carlos Barbosa either by mail to Environmental Analysis Unit, NYS Housing Trust Fund Corporation, 38-40 State Street, Albany, New York, 12207 or by Email to environmental.comments@hcr.ny.gov. HCR certifies to HUD that Carlos Barbosa in their capacity as Certifying Officer consents to accept the jurisdiction of the Federal Courts if an action is brought to enforce responsibilities in relation to the environmental review process and that these responsibilities have been satisfied. HCR's approval of the certification satisfies its responsibilities under NEPA and related laws and aut
