A relocated home for the Roxbury-based National Center of African-American Artists, BJ’s Wholesale Club and Planet Fitness were part of the Tremont Crossing project.

The development team behind the 1.1 million-square-foot Tremont Crossing project planned for a massive, vacant, city-owned lot in Roxbury has lost the support of the Boston Planning & Development Agency and is losing its right to develop the lot, known as Parcel P-3.

The Bay State Banner was first to report the news.

Feldco/Elma Lewis Partners had been designated as the site’s developer in 2007, but hit a series of delays ranging from soil contamination, to a lengthy approvals process and, finally, an inability to secure financing for the project, which would have been anchored by a 727-unit residential building, a BJ’s Wholesale Club and a new home for the Museum of the National Center of Afro American Artists.

The team’s development designation will expire on Oct. 31, and the BPDA board will not vote to extend the designation for an additional term, the agency confirmed Monday, stating the agency had “lost confidence in the viability of the project” due to the financing issue. While the project would have included 102 affordable units, it had been the frequent target of some community activists who believed it would hasten gentrification in the neighborhood.

“The residents of Roxbury deserve a development at Parcel 3 that will create good paying jobs, economic development, affordable housing, cultural space, and more,” BPDA Director Brian Golden said in a statement. “While we are disappointed that the current project cannot move forward due to the development team’s lack of a viable funding source, we believe that opening this parcel up for new opportunities will allow for a community-led vision, guided by PLAN: Dudley, to determine the future of this important parcel.”

The PLAN: Dudley process has been steadily managing a development process for numerous city-owned parcels in and around Roxbury’s commercial core of Dudley Square. Projects for the first set of four parcels were recently formally proposed to the BPDA after going through a community vetting process, and would bring nearly 200 affordable units and 65 market-rate units to the neighborhood. PLAN: Dudley requires all housing developments to make one-third of all units affordable to low-income tenants or buyers and one-third affordable to moderate-income tenants or buyers, with only one-third allowed to be offered at market rates.
