Dan Biederman

Bryant Park Corporation

Bryant Park Corporation was co-founded in 1980 by Biederman and others, and set out to improve the park, including a private security staff to confront unlawful behavior immediately.

In 1988 BPC closed the park in order to undertake a four-year project to build new park entrances for increased visibility from the street, to enhance the formal French garden design (with a lush redesign by Lynden Miller), and to improve and repair paths and lighting. BPC’s plan also included restoring of the park’s monuments, and renovating its long-closed restrooms, and building two restaurant pavilions and four concession kiosks.

After a four-year effort overseen by Biederman, the park reopened in 1992 to widespread acclaim. Called “a triumph for many” by NY Times architectural critic Paul Goldberger, the renovation was lauded for its architectural excellence, and praised as "The Best Example of Urban Renewal" by New York Magazine. It made Time Magazine's list of "Best Design of 1992". Many awards followed, including a Design Merit Award from Landscape Architecture Magazine, which noted that the park was "colorful and comfortable....and safe". In 1996, the Urban Land Institute honored BPC with a ULI Award For Excellence. ULI remarked that the renovation "turned a disaster into an asset, dramatically improved the neighborhood, and pushed up office rents and occupancy rates."

34th Street Partnership

The 34th Street Partnership was founded in 1989 when Mayor David Dinkins and property owners on 34th Street asked Biederman to bring his expertise to the area around Madison Square Garden in order to prepare it for the 1992 Democratic Convention. The 34SP BID manages the 34th Street District. In January 1992 the Partnership opened a $6 million annual program of security, sanitation, tourist information, public events and debt service on a major capital improvement bond of $25 million for improvements to the district's street, sidewalks, and plazas.

The capital improvements have been widely regarded as a prime reason for the rise in 34th Street property values that began in the 1990s and continues to this day,with "rapid appreciation on nearly every street."

Grand Central Partnership

In 1984 Mayor Ed Koch, at the behest of executives from many of the Fortune 500 companies that are headquartered near Grand Central Terminal in New York, asked Biederman to bring his efforts to bear on making the downtrodden area around the terminal commensurate with the offices nearby. Biederman formed the Grand Central Partnership, a Business Improvement District. Biederman left GCP in 1999.

Chelsea Improvement Company

In 2007 some property owners in New York’s Chelsea neighborhood asked Biederman to work on a five-block area on the western edge of the neighborhood, and the Chelsea Improvement Company was formed. CIC worked with NYC’s Department of Transportation to develop a “green triangle”, a pedestrian-friendly area with movable chairs and tables.

The organization's efforts were described as "Cheering Up Chelsea" in an article in the New York Post.
