Westchester IDA Marks Banner Year in 2023 With $2B, Propelled by Regeneron Expansion

By JOHN JORDAN – February 2024

WHITE PLAINS—The $1.8-billion expansion of Regeneron Pharmaceuticals has once again put economic development activity incentivized by the Westchester County Industrial Development Agency in the billions of dollars.

The agency reported that 2023 was another record year as it finished the year with final and preliminary approvals of financial assistance for private investment development projects valued at approximately $2.2 billion. This follows up the 2022 calendar year, which saw the IDA provide financial incentives for projects with an estimated value of $1.84 billion.

In 2022, the IDA provided incentives for the first phase of Regeneron’s expansion at its facilities in Greenburgh and Tarrytown. Last year, the agency once again approved incentives for the pharmaceutical firm’s larger expansion of its corporate headquarters complex.

Like 2022, the Regeneron project was the IDA’s largest by far in 2023. The expansion project is expected to create more than 2,700 construction jobs, including 1,867 direct jobs resulting in more than $273 million in worker earnings and $357 million in economic activity in Westchester County, the IDA reported.

The $89.2-million Modera project in White Plains, developed by Mill Creek Residential Trust, calls for adaptive reuse of a vacant light manufacturing facility into a 189-unit multifamily rental building with considerable affordable units.

Westchester County Director of Operations Joan McDonald, who chairs the IDA, pointed to many strategic initiatives that are ongoing and successful. These include the Regeneron’s expansion, biotech, advanced manufacturing and clean energy sectors. She noted the wide range of projects that received incentives was “truly impressive.”

She also listed transit-oriented developments, affordable senior housing, research labs, adaptive reuse housing and energy storage facilities.

Ms. McDonald noted that while the $10-million projects in Ossining and Yorktown will not involve significant job creation, it does “send a message that we are committed to alternative energy.”

“In addition to local developers, we are also seeing national real estate companies that are attracted to the highly educated workforce and excellent quality of life that Westchester has to offer,” Ms. McDonald added.
