After months of community meetings and conversations about the Blue Hill Avenue corridor and the redesign of Mattapan Square, final decisions by the Wu administration on what’s next are expected by the end of the year.

At stake are key concept designs for the large-scale renovation of a corridor that hasn’t seen significant change in more than 50 years that include whether to have a center-lane MBTA bus route from Grove Hall to Mattapan Square, whether to keep the angled parking in Mattapan Square, whether to squeeze parts of the avenue into one vehicle lane to accommodate bicycle lanes, and whether to move statues in Mattapan Square.

City officials have their preferences – such as having the center-lane bus that carries a $15 million federal grant with it – but planners insist that nothing has been decided.

According to Kirstie Hostetter, a planner for the Boston Transportation Department (BTD) who runs the Blue Hill Avenue corridor redesign process, the agency is now working on an engagement report that will be handed over to the administration and the public in the fall after which decisions will be made by the mayor and her administration.

“Fundamentally,” said Hostetter, “the decisions will be informed by the many, many conversations we’ve had with so many about Blue Hill Avenue.”

The process began with widespread outreach and monthly meetings last October and wrapped up in July to allow the BTD team to assemble all they’ve heard – including arguments for and against various parts of the avenue rehab.

Meanwhile, the Mattapan Square redesign process is on a separate track and officials have been holding monthly Zoom meetings, as well as using consultants and street teams. That process started earlier than the Blue Hill Avenue planning due to work with the city’s Age Strong Commission.

BTD Project Director Charlotte Fleetwood noted they will be wrapping up the engagement soon after their Sept. 15 Zoom meeting. The three concepts at play include leaving things as is, keeping the angled parking and introducing a center-lane bus, or introducing parallel parking and a center-lane bus.

While the second alternative allows for keeping more parking, it doesn’t include a bike lane and has fewer trees. The third option include the bike lane and more trees but comes with a significant loss of parking.

There is also the issue of the historic “RISE” statues, and whether to move them, and if they’re moved – to where. To accommodate a left turn bus lane into the station (instead of circling around into Milton and back), the statues would need to be moved. There is currently what seems a preferred plan that would move them to plazas in front of the T-Mobile store and the Haitian restaurant.

One thing everyone agrees on, it seems, is the intallation of a crosswalk at the southern end of Mattapan Square going in and out of Milton, as well as more accessible crossings throughout the Square for the disabled and the elderly.

“We’ll report what we’ve seen and heard: that people have common ground on the new crosswalk, the sculptures, and the crosswalk inaccessibility now,” said Fleetwood.

Her report will come out along with the Blue Hill Avenue report, after which, Hostetter said, they will begin to merge Blue Hill Avenue and Mattapan Square into one process. Construction in some form is expected in 2025 at the earliest.
