The Site, Located on West 100th Street Between Amsterdam Avenue and Columbus Avenue, Will be Redeveloped to Include Market-Rate and Permanently Affordable Housing Along with a New Bloomingdale Library Branch and off-site, modernized facilities for The Department of Mental Health and Hygiene

New York City Economic Development Corporation (NYCEDC) today announced the release of a Request for Proposals (RFP) from qualified parties for the long-term ground lease or a sale of the West 100th Street Site. The City-owned site, located on West 100th Street between Amsterdam Avenue and Columbus Avenue in Manhattan, currently houses the New York Public Library’s (NYPL) Bloomingdale branch and New York City Department of Health and Mental Hygiene’s (DOHMH) Riverside Health Center. This redevelopment project will deliver mixed-income housing, along with a new library branch, and off-site, modernized facilities for the Department of Health and Mental Hygiene.

Introduced in January 2025, “City of Yes for Families” aims to make New York City the best, most affordable place to raise a family. A key pillar of this plan is the “Living Libraries” initiative, which focuses on jointly developing new libraries and housing. The upcoming redevelopment of the Bloomingdale Branch will be the fifth project of its kind, providing New Yorkers with a new state-of-the-art library and delivering much needed housing. Previous examples of Living Libraries projects include NYPL’s Inwood Library in Manhattan and Grand Concourse branch in The Bronx, as well as Brooklyn Public Library’s Brooklyn Heights and Sunset Park branches.

The RFP seeks to accomplish the following goals:

• Housing Production: Generate high-quality housing, including permanently income-restricted affordable housing, that helps meet the City’s housing needs. Utilizing the tools under City of Yes for Housing Opportunity, Respondents should propose to rezone the site to maximize the number of residential and affordable units.
• Support Civic Services: Develop a plan that thoughtfully formulates, funds, and executes the delivery of suitable new space for the existing civic uses on the site, including: 
     ◦ The design and construction of a new Library Branch in the redevelopment.
     ◦ Providing temporary library services in an offsite location during demolition and construction.
     ◦ The permanent relocation and fit out of the existing DOHMH facility uses that are currently housed at the site.
• Enhance the Public Realm: Create a welcoming, vibrant public realm that smoothly integrates the new development into the neighborhood context, and provides a thoughtful, functional and attractive space for the new Library Branch accessible at ground level without the need for public subsidy.
• Advance Sustainability: Make progress toward the City’s sustainability, energy efficiency, carbon neutrality, and resiliency goal.
• Support Community Development: Responsibly develop the Project to create quality construction and building service jobs while adhering to 485-x wage standards and labor protections.

The Bloomingdale Library originally opened in 1896, as part of the New York Free Circulating Library and was incorporated into The New York Public Library system in 1901. Sixty years later, the branch moved to its current location—at 150 West 100 Street—where it continues to offer valuable resources and provide essential services, such as English language classes, early literacy programs, after school tutoring, and popular teen workshops.

DOHMH has a variety of uses at the site. The DOHMH Health Academy has been providing courses, continuing education and various licensures since 2012. The Riverside Sexual Health Clinic has offered low- to no-cost services to the surrounding community with a commitment to compassionate care. The site also houses office space for NYC Health’s programs for School Health, Nurse Family Partnership, and Newborn Home Visiting.

For more information, visit the Bloomingdale RFP page. NYCEDC will facilitate optional site visits that will take place at 10 AM on Thursday, February 19, 2026 and must RSVP by Tuesday, February 17, 2026. Responses to the RFP are due by 4 PM ET on Thursday, April 23, 2026.
