The Esplanade Association (TEA) is putting the finishing touches on blueprints for one of the largest additions in the park’s history, with both a new building and several sports fields in the pipeline.

The Charlesbank Landing project has a public meeting scheduled for June 20 at the West End Public Library, the proposal’s first since it was unveiled last June. The general design of the project is now complete, with only the last bits of funding and some nitty-gritty details like what chairs to buy still undecided.

“Right now, as we’re working to finish our designs and complete our permitting processes, we’ll start to see more design details emerge,” said Ali Badrigian, TEA’s director of projects and planning. “People at the meeting on the 20th will be able to see the placement of new items like benches and bike racks and finalizing some of the connections to existing pathways.”

The core of the project remains unchanged, a new building at the northern tip of the Esplanade serving triple duty as community space, visitor center and staging ground for staff.

Visitors will have access to public bathrooms, a staffed help desk and free wifi. There will also be space for a cafe business with seating both inside and out.

While TEA’s much-needed staging area won’t be open for tours, the updated blueprints have finally locked down what kind of sports field will be next door. Planners settled on hard multisport courts ideal for tennis and basketball, though they will also be painted for use in hardcourt soccer or roller hockey.

“We imagine it’ll be a really popular amenity, especially since basketball and tennis courts used to be in that area but were removed. We’ve heard a lot of people missing those and we’re excited to bring them back,” Badrigian said.

Planners are working now to get the last permits they need. They’ve already secured approval from the Boston Conservation Commission and the Massachusetts Historical Commission, as well as passing state-level environmental review.

Up next is the Boston Landmarks Commission, as well as a continued review by the MA Department of Environmental Protection. Badrigian says those should wrap up later this summer.

There’s also the matter of funding, which is almost but not quite locked in with 10% of the $20 million budget still extant. Fully $12 million of that is covered by a record-setting donation from TEA itself, but planners are looking to philanthropy for that last $2 million.

“There are some grant foundations that have been really generous, and our team has a couple other options that we’re looking at. But it’s all supported through the generosity of folks that want to further our mission,” said Badrigian.

The next big step after the July meeting is putting the project out to bid, which is expected to happen later this summer. The timeline for a grand opening has been moved back slightly, now eyeing summer 2026.
