It's looking like a groundbreaking year for Boston's development scene.Mayor Wu has plans to shake up the Boston Planning & Development Agency and introduce a new city office for planning and design.

As we await details on the future of our city's planning process, here are five major development projects + proposals to know about.

Parcel 12

Eyes up to see the ongoing construction on this air rights development. The project, expected to be completed this summer, will consist of a public plaza between two towers over the Mass Pike + help connect the Back Bay and Fenway neighborhoods. Plus, there's another development planned for the Pike, called Fenway Center.

Dorchester Bay City

This proposal by Accordia Partners would completely transform the Columbia Point waterfront into a mixed-use community space. Plans include a 6,300-sqft public pavilion, alearning and innovation center + affordable on-site housing. This project is currently under review, and the public comment period is open until Feb. 28.

The Back Bay shopping destination is undergoing some big changes, primarily to the top of the building. The new three-floor observation deck is scheduled to open later this year with panoramic views, a selfie experience, and interactive exhibits.

MGH Cambridge Street Expansion

Mass General Hospital recently broke ground on its 1.5 million-sqft campus expansion. The development project along Cambridge Street has a price tag of almost $2 billion and will include the Mass General Cancer Center + Corrigan Minehan Heart Center.

Suffolk Downs

Opening to the public this spring, the former East Boston racetrack is transforming into The Stage at Suffolk Downs. The 8,500-seat seasonal, outdoor concert venue will be located at the infield of The Track at 525 William F McClellan Highway.
