County Of Suffolk

County of Suffolk Transportation Division, operating as the Department of Public Works Transportation Department and headquartered in Yaphank, New York, is a U.S. local government entity that acts as a federal grant recipient for transit capital and operating assistance under the Federal Transit Administration's formula and project grant programs. The division operates exclusively as a prime recipient—no subrecipient relationships or contract work—with all 52 recent federal awards originating from the Federal Transit Administration (51 awards) and the Environmental Protection Agency (1 award). Combined obligated funding across the recent award portfolio totals $489.7 million.

Suffolk County Transportation Division's work centers on paratransit and fixed-route bus system modernization, operating assistance, and corridor planning for Suffolk County Transit and the Suffolk County Accessible Transportation (SCAT) paratransit system. Representative recent awards include a $35.88 million Federal Transit Formula Grants award (CFDA 20.507) issued September 2, 2025, for capital improvements including procurement of 29 replacement paratransit buses, 24 replacement 35-foot hybrid electric transit buses, 29 replacement 30-foot transit buses, 157 mobile radios, approximately 40 bus shelters, and 3 service vehicles through June 30, 2028; a $4.255 million Enhanced Mobility of Seniors and Individuals with Disabilities award (CFDA 20.513) issued August 19, 2026, for operating assistance delivering 50 percent reimbursement for paratransit service beyond the ADA-required three-quarter-mile corridor through September 30, 2027; and a $1.272 million Buses and Bus Facilities award (CFDA 20.526) issued September 2, 2025, for procurement of nine replacement paratransit buses and related equipment through January 31, 2028. Additional work includes final design engineering for the NYS Route 110 Bus Rapid Transit corridor and pandemic emergency operating assistance under American Rescue Plan and CRRSA funding.

The division concentrates funding exclusively within the Federal Transit Administration—51 of 52 awards—making it a single-agency customer relationship. Award activity accelerated from one award in 2021 to seven in 2022, then stabilized at three to six awards annually through 2026. Seven awards with ultimate completion dates falling within the next twenty-four months face recompete exposure. The division operates as a child entity of County of Suffolk NY, the parent local government unit located in Hauppauge, New York.
