The Children’s Museum’s flood prevention initiative emerged as the most pressing topic, with the museum seeking approval for the vertical discontinuance of portions of public ways on Congress Street and Sleeper Street. The proposal involves installing waterproofing and new brick facades to protect against potential flooding exacerbated by anticipated sea-level rise. The discontinuance area is planned to extend from one foot above the building to 3.4 feet below grade and 6.6 feet above grade. This project has garnered support from the Office of Neighborhood Services, and the appraisal necessary for the project has been completed and submitted. However, questions were raised about the timing and process for acquiring city council approval for the discontinuance, with legal counsel clarifying that it could take several weeks. Concerns about potential delays in construction and coordination with upcoming public works improvements on Sleeper Street were addressed, with assurances that effective communication among all parties would be prioritized to avoid setbacks.

The approval of this project is timely, given the broader context of climate change and its implications for Boston’s resiliency planning. During the meeting, a public comment highlighted the city’s vulnerability to rising sea levels, particularly in neighborhoods like South Boston, prompting a discussion on the need for comprehensive climate resilience strategies. The commission acknowledged the significance of climate change and mentioned various strategies being implemented across the city, such as deployable flood barriers and reconstruction efforts aimed at protecting buildings. The Office of Climate Resilience was cited as a resource for further discussion on ongoing projects related to climate adaptation.

In addition to the Children’s Museum project, the commission addressed several other infrastructure proposals. One notable item was the petition from Monarch Development LLC for the redevelopment of 736 to 742 East Broadway in South Boston. The proposed project involves demolishing an existing three-story mixed-use building to construct a four-story structure with residential units and ground-floor commercial space. The development will feature a six-space surface parking lot, sidewalk reconstruction, and the installation of two Japanese tree lilacs in designated tree pits. The commission members were informed of the necessity for final approval from the disabilities commission, which the proponents are pursuing.

Another topic was the proposal from Northeastern University concerning the abandonment of a private alley and the relocation of public alley lines for the new Matthews Arena project. This project involves constructing a new arena for hockey, basketball, and other events, covering approximately 310,000 square feet. The development requires the abandonment of an existing 10-foot private alley and adjustments to the public alley to accommodate the new construction. The plans include the construction of new concrete sidewalks, curb reconfigurations, and the installation of new street trees and bike racks.

The commission also deliberated on accessibility improvements for the MBTA’s downtown crossing station. Proposed enhancements include replacing existing elevators and constructing new below-grade elevators to improve access between transit lines. The project necessitates the installation of vent enclosures at two locations, with a simple design that allows for potential informational signage. Coordination with the mayor’s office of arts and culture was discussed, with the possibility of incorporating public art on the structures. The MBTA confirmed its responsibility for maintaining the structures.
