Regeneron Pharmaceuticals, Inc. leases approximately 1 million square feet of space at the Landmark at Eastview in Mount Pleasant, NY.

GREENBURGH, NY—Biopharmaceutical firm Regeneron Pharmaceuticals is planning a major expansion of its operations in Westchester County that could result in one million square feet of newly developed space in the Town of Greenburgh.

Regeneron currently occupies more than one million square feet of leased space at the Landmark at Eastview in the Town of Mount Pleasant. The firm has filed plans with the Town of Greenburgh on a major expansion of its operations on property it owns adjacent to the Landmark at Eastview. Regeneron has not set a firm construction timetable and in a prepared statement says it is pursuing the development based on its projected future growth.

The company is seeking approvals from the town for nine buildings totaling 1,016,190 square feet of research and development and related space, including five parking structures (approximately 2,500 parking spaces), and improvements. Regeneron owns the 100.17-acre parcel that is situated entirely in the Town of Greenburgh on the west side of Saw Mill River Road (Route 9A) approximately 300 feet from the intersection of Old Saw Mill River Road and Grasslands Road (Route 100C). The property is located in the town's Planned Economic Development District.

In a statement Regeneron officials said of the company's plans before the Town of Greenburgh: “Regeneron has called Westchester home for over 28 years and continues to grow and invest in the community. Our application to the Town of Greenburgh affords us the opportunity to expand in the future if needed. We are currently in the planning stages and are seeking site plan approval. We look forward to working with the town and our community partners as we go through this process.”

Regeneron affiliate Loop Road Holdings made a presentation to the Greenburgh Town Board in a work session earlier this month. Joanne Deyo, VP facilities for Regeneron Pharmaceuticals and Loop Road Holdings, led the presentation. The nine buildings would be built on 60 acres.

Deyo and other Regeneron officials stressed that no development timeline had been set and that construction would match its business and employment needs. No development cost for the project was revealed at the session.

Regeneron currently employs 5,000 workers worldwide and about 2,500 workers at its Landmark at Eastview campus. Deyo told the Town Board that if the expansion project were fully built-out it would double its Westchester workforce, or result in 2,500 new jobs.

Last year, Regeneron completed a $100-million expansion project when it opened two new buildings totaling approximately 300,000 square feet of space at the Landmark at Eastview.

Greenburgh Town Supervisor Paul Feiner says of the proposed project, “This is for us really, really exciting because I think Greenburgh now is going to be one of the top two biotech centers in New York State.” Feiner says Regeneron officials told the town that the project would be phased in over a period of up to 10 years.

Feiner says the property was rezoned last year to the town's Planned Economic Development District that allows for major projects. He relates that while large projects usually spark some local opposition, because of the rezoning and the property's location in a commercial center away from residential housing, “This application will be pretty unusual in Westchester because if the Town Board had its preference we would approve it in five minutes.”

The proposal also includes the preservation of more than 40 acres of open space and improvements to local infrastructure. Feiner says the town could reap in building permit fees alone anywhere from $7 million to $8 million over the 10-year period. Regeneron, which achieved LEED-Gold designation on its last two buildings at Landmark at Eastview, would be looking to achieve that LEED status as well with its expansion space in Greenburgh.

Greenburgh officials during the work session stated that the proposed project conforms to the zoning and could be approved in the next four to six months.

William Mooney III, director of the Office of Economic Development for Westchester County, says that Regeneron has not contacted the county's Industrial Development Agency for possible incentives as yet.

If the project moves forward it would only enhance Westchester County's emerging biotechnology sector. Westchester County is pursuing a $1.2-billion bioscience park at a 60-acre vacant parcel at the Grasslands campus in Valhalla.

The project called the Westchester BioScience & Technology Center, calls for approximately three million square feet of space to be built in phases. The total project site includes 60 acres of vacant county-owned land known as the “North 60” and an adjacent 20 acres of vacant property owned by Fareri Associates of Greenwich, CT. The county is looking to finalize a long-term lease deal with Fareri to begin development of the project.

Last year, Regeneron completed a $100-million expansion project when it opened two new buildings totaling approximately 300,000 square feet of space at the Landmark at Eastview.

Greenburgh officials during the work session stated that the proposed project conforms to the zoning and could be approved in the next four to six months.
