Dear Supporter,
The Fight Against Northwell Continues
We are writing to update you on our continuing efforts to fight the massive Lenox Hill Hospital project.
As you may have seen in the news recently, CPOLHN -- together with other community stakeholders including the non-profit CIVITAS, several coop buildings on the surrounding blocks, and individual neighborhood residents -- filed a lawsuit on December 9, 2025, against the City of New York and Northwell Health to challenge the City’s approval of the Lenox Hill Hospital expansion project.
Northwell’s proposed hospital enlargement requires a dizzying array of zoning entitlements granted by the City Council in August. As they stand, the City approvals enable Northwell to increase the hospital’s existing floor area by 78%, resulting in a massive development with a building height on Lexington Avenue of 370 feet. The maximum building height at Lexington Avenue before these approvals was only 175 feet. The zoning entitlements will allow Northwell to construct a new hospital building with a floor plate of over 30,000 sq. ft., which when combined with the new building height is comparable to the massing of enormous commercial buildings such as the Empire State Building, Freedom Tower, and One Vanderbilt. Such bulk is found only in the City’s business districts. The proposed construction is “estimated by Northwell,” to take 8 to 10 years.
The lawsuit we have filed, called an Article 78, challenges these zoning approvals in the New York County Supreme Court. It sets forth the reasons why the Court should nullify the zoning approvals granted to Northwell by the City Planning Commission and NY City Council:
- The City’s approvals constitute an illegal spot zoning enacted solely for Northwell’s benefit to the detriment of the surrounding community.
- The City’s approvals violate the New York General City Law, as the zoning approvals granted to Northwell are not in accordance with the City’s well-considered plan and do not promote public health, safety, and general welfare.
- The City’s approvals failed to meet the environmental review standards mandated by New York’s State Environmental Quality Review Act (SEQRA) and New York City’s City Environmental Quality Review (CEQR), including most egregiously that the Final Environmental Impact Statement prepared for the project failed to consider that the rezoning approved by the City Planning Commission and City Council would allow Northwell to abandon its plans for the proposed hospital project and as-of-right construct themselves (or sell to a developer) a mid-block residential tower scaling to an astronomical height of approximately 1,000 feet.
- The Upper East Side of Manhattan is already oversaturated with the highest concentration of inpatient hospital beds of any neighborhood in the City. Therefore, the resources for hospital expansion would be better spent in other areas of the City that are hospital deserts in desperate need of beds, while making a more modest investment in needed improvements to continue Lenox Hill Hospital to serve as a community hospital.
In addition to the lawsuit, we will be challenging the hospital’s Certificate of Need application at the NYS Department of Health in Albany. There will be opportunities to testify in opposition once the project is on the agenda in 2026.
Our team is lobbying in Albany, meeting with government officials, including Senator Liz Krueger, and will continue to do so with current and incoming electeds.
We believe that our actions will either annul the NYC Council zoning approvals or lead to direct discussions with Northwell to bring the building down to a reasonable size and scale for a residential neighborhood.
