A proposed development that could create a walkable and bicyclist-friendly area with offices, retail, and residences or a hotel over the Mass. Pike in the Back Bay could be ready in 2022, according to plans filed with the city.

The Parcel 12 project, proposed by S&A P-12 Property, a limited liability company affiliated with the commercial real estate firm Samuels and Associates, would sit at the intersection of Massachusetts Avenue and Boylston and Newbury streets, according to a letter of intent filed with the city.

Talks of the roughly 643,000-square-foot development have gone on for about 20 years, according to the plans.  In total, there would be about 429,000 square feet of office space, 150,000 square feet of hotel or residential space, and about 55,000 square feet of first- and second-floor retail, plus 150 underground parking spaces, the plans show.

The plans call for two towers set atop a platform over the Pike. On the bottom levels would be retail. One tower would reach 18 stories on top of two stories of retail, the plans say. A second building would include one floor of retail and then stretch 11 stories high with 150 units of either hotel rooms or residences. 

The project is open for public comments until July 22, the Boston Planning and Development Agency website says.
