The Boston Transportation Department (BTD) is planning a redesign of the South End’s Columbus Avenue, though some residents are concerned that the city hasn’t done enough to engage the community.

During an August meeting of the South End Forum, a group of neighborhood associations, BTD officials outlined their current plans for the stretch of Columbus Avenue between Massachusetts Avenue and Clarendon Street. Along with adjusting a few dozen sidewalk ramps, BTD would resurface and redesign the street, which badly needs repairs.

Beyond those details, however, the department had not yet decided on what else the redesign would include.

The redesign of Columbus Avenue is a part of the broader Connect Downtown project, through which the city hopes to improve pedestrian crossings and expand the city’s separated bike lane network. This project is unrelated to BTD’s recent decision to make permanent the bike lanes on Columbus Avenue between Clarendon and Arlington Streets.

South End leaders have said that, in the months since August, they have received few, if any, updates from BTD regarding the plan.

“All we’ve gotten are hints,” said Steve Fox, founder of the South End Forum. “It’s hard to say what’s actually going on.”

That lack of communication is concerning, Fox said, especially because some potential features of the yet-to-materialize plan are controversial.

For example, one unofficial proposal would remove Columbus Avenue’s cobblestone median to accommodate separated bike lanes on both sides of the street. Besides charming many South End residents, that median also serves as extra parking for the parishioners of Union United Methodist Church, an historically Black church on Columbus Avenue. According to Fox, the city said it doesn’t want to maintain the median’s cobblestones, which are in poor shape and have become a tripping hazard.

“Who decided that we didn’t want to support cobblestones? Was this decided within the offices of city hall? Was it debated by our city council? Was community input garnered?” Fox asked.

Because they feel that BTD hasn’t adequately considered their concerns, many South End residents are upset with the process.

“The number one concern I hear from South Enders is that the community engagement process does not meet the needs of the South End community,” Fox said.

Fox hopes that before it decides on a plan, the BTD facilitates a more robust community engagement process with community-wide meetings. Such a process, he said, should be a “partnership” and “joint venture” in which everyone can voice their concerns.

“We want to be partners, full partners, not just an audience for their decision-making,” Fox said. “That’s the nexus of the issue for us.”

Bob Barney, president of the Claremont Neighborhood Association, a group whose territory includes part of Columbus Avenue, agreed with Fox on many points.

Barney said that, though BTD has tried to engage different parts of the South End community, it has done so in silos without facilitating much conservation between groups. “I think the engagement process should be with everybody at the same time so we all get to hear each other,” Barney said. “We need to work together for the best solution for the most people.”

Barney added that, when BTD was planning its major redesign of Tremont Street a few years ago, it hosted community-wide meetings, some of which attracted nearly a hundred residents.

“I think that really needs to happen with Columbus Avenue,” Barney said. “And that should happen soon.”

In some ways, however, Barney and Fox hope BTD improves upon the engagement strategies it used during the Tremont Street project. During that process, they both said, many South End residents felt that BTD did not incorporate their opinions into the ultimate design, and some are worried the same will happen with Columbus Avenue.

BTD and South Enders still have time to cooperate on a plan that works for everyone. At the earliest, construction could begin toward the end of next summer, according to the August meeting.

BTD officials did not respond to requests for comment as of deadline.
