County Of Suffolk

County of Suffolk, operating as the Department of Economic Development & Planning, is a U.S. local government entity (county) that acts as a prime recipient on federal infrastructure and community development grants, with 60% of its recent awards in a prime role and 40% as a sub-recipient. The organization is headquartered in Hauppauge, New York, and operates under the parent entity County of Suffolk NY.

Suffolk County's federal grant footprint centers on transportation infrastructure, economic development, and coastal resilience. The organization has received four prime grants from the Federal Highway Administration totaling at least $5.2 million in combined obligated dollars. Representative work includes a $4.765 million Project Grant under the National Infrastructure Investments (RAISE) program (CFDA 20.933) awarded September 12, 2024, to fund planning and design of the Long Island Greenway East (Phase II) project, with completion targeted for June 30, 2027; a $395,500 Project Grant under the Safe Streets and Roads for All (SS4A) program (CFDA 20.939) awarded January 23, 2026, for supplemental planning and demonstration activities addressing roadway fatalities and serious injuries, completing November 23, 2029; and a Cooperative Agreement under the Regional Infrastructure Accelerator (RIA) program with the Federal Highway Administration awarded May 1, 2023, running through April 30, 2027. Suffolk County also holds two Project Grants from the Department of Housing and Urban Development's Assistant Secretary for Community Planning and Development (CFDA not specified) under the Economic Development Initiative, Community Project Funding program, both awarded February 17, 2023, and running through August 31, 2031. In its sub-recipient capacity, the county received a federal grant sub-award from the New York State Division of Homeland Security & Emergency Services dated January 27, 2025, for the Enhancing Coastal Resiliency Through Integrated Salt Marsh Management Project.

Customer concentration is distributed across four federal agencies — the Federal Highway Administration (3 awards), the Federal Emergency Management Agency (4 awards), the Department of Housing and Urban Development (2 awards), and the Department of Energy (1 award). Combined dollars obligated across all ten awards total $12.2 million. Activity volume is sparse and episodic: one award in 2019, three in 2023, one in 2024, one in 2025, and one in 2026. Only one award faces ultimate completion within the next twenty-four months. Suffolk County does not hold positions on federal contract vehicles or IDIQs and does not operate as a federal contractor.
