Shoreline Protection Project

U.S. Army Corps of Engineers, New York District
Published Dec. 21, 2023

DESCRIPTION: Hashamomuck Cove is located on the north (Long Island Sound) shore of the north fork of Long Island. This area includes Southold Town Beach Cove, Hashamomuck Cove, and Pebble Beach Cove. This area includes several businesses and private homes and is subject to substantial overwash and erosion during coastal storms. Additionally, County Road 48 may be subject to undermining. The Study is focused primarily on reducing coastal storm and erosion risks to critical infrastructure, including County Road 48 and utilities along its corridor, and other nearby structures. The study will look to reduce risk of failure or disruption along Route 48,

AUTHORIZATION: House of Representatives, Committee on Transportation and Infrastructure, Resolution, Docket Number 2773.

STATUS: The District initiated the Reconnaissance Phase in July 2007. A Reconnaissance report was completed in July 2008 and approved by the U.S. Army Corps of Engineers, North Atlantic Division in September 2008. This report defines the problems, needs, and opportunities for the study area and demonstrates federal interest. The New York District executed a Feasibility Cost Sharing Agreement (FCSA) with the New York State Department of Environmental Conservation in December 2012 for a feasibility study to examine potential alternatives that will reduce the risk of damage to the shoreline and private/public structures including County Road 48. After the Sandy storm event and the passage of P.L. 113-2, a new FCSA was signed in March 2014 and confirms that the study will be completed at 100% Federal cost.  The Final report recommending beachfill 25 ft. in width over the study area with renourishment approximately every 9 years was signed by the Chief of Engineers on December 10, 2019 and authorized by Congress in the Water Resources Development Act of 2020. $1,000,000 to be fully Federally funded by the Disaster Relief Supplemental Appropriations Act of 2022 is available for design work pending the signing of a design agreement with a non-Federal sponsor (that sponsor would not need to cost share the design effort because 100% Federal funding is available).
