Widett Circle seafood vendors propose new South Boston Waterfront facility

After listing their longtime home at Widett Circle in South Boston for sale, the seafood vendors of New Boston Food Market, in conjunction with Boston Global Investors, propose to construct a new 79,000-square-foot multi-tenant facility for seafood processing, storage and refrigeration on the South Boston Waterfront. The proposed building would be a two-story, light industrial building of approximately 56,000 gross square feet on the first floor, with an office mezzanine area on the second floor of approximately 23,000 gross square feet. The building would be constructed on the vacant Parcel M of the Raymond L. Flynn Marine Park, located at 3 Dolphin Way. The proponents have filed a Letter of Intent (LOI) with the Boston Planning & Development Agency (BPDA) to construct the proposed facility and anticipate filing a Project Notification Form (PNF) for the project upon completion of negotiations with the BPDA, Parcel M’s owner, for a ground lease.
