Chapter 91 license has been granted to Chicago-based Equity Office Properties by the state Department of Environmental Protection for its redevelopment of Russia Wharf.

This is the final hurdle for the long-planned project on land that contains three historic buildings at Fort Point Channel.

Although the original plan for the property included a 300-room hotel, that was later watered-down in favor of a “boutique� hotel, and there is no hotel in the final plan.

According to GlobeSt.com:

Under the current plan, EOP will restore the Russia building at 530 Atlantic Avenue and “is restoring significant historical elements of the other two buildings, Graphic Arts and Tufts,� which are at 270 and 286 Congress, respectively.

These three will be converted into 200 housing units and 31,000 SF of retail, civic and restaurant space. Above them, Equity will build a new 31-story office building with an aggregate of 500,000 SF. There will also be outdoor public areas, including one-third acre of open space.

The historic, seven-story buildings now aggregate 313,000 SF. They were built in 1899, renovated in 1980 and are currently leased to office tenants.

The architect is Boston-based Childs Bertman Tseckares Inc.
