In order to ensure a “full community review,” Boston City Hall has announced a public meeting for concerned residents ahead of any plans to site recovery programs in Mattapan for homeless people displaced by the closing of the Long Island Bridge.

The meeting, set for Tuesday, Jan. 6, at 7 p.m. at the Mildred Avenue Community Center will include Mayor Martin Walsh, the office of the Chief of Health and Human Services, and the Boston Public Health Commission (BPHC) who will discuss a possible location off River Street.

Dr. Huy Nguyen, the BPHC’s interim executive director, will present an overview of the planned use for the building and representatives will be on hand to field questions.

“It is important that there is a full community review process prior to the facility opening,” said Walsh spokesperson Melina Schuler.

BPHC’s Building N on River Street, with 74 beds, is expected to open this month. The adult day care location next door, expected to offer 20 program beds or 50 emergency beds, was also expected to be operational this month, according to the city which has been renovating both locations.

The process has received considerable backlash from Mattapan residents and elected officials for what they feel is a less-than-rigorous public outreach process.

In October, city officials announced that they would retrofit the buildings, which are owned by BPHC and set back from River Street near the Foley Senior Residences, to house programs for people recovering from substance abuse: one for men nearing the end of prison sentences, and the other for people who need a short-term residential program.

“Next week’s community meeting is an opportunity to continue the meaningful and necessary conversation with those directly impacted by the relocation of recovery and treatment programs in Mattapan,” said BPHC spokesperson McKenzie Ridings in a statement on Monday.

A second meeting, still in the works, will revisit discussions about the ongoing EMS garage construction at BPHC’s River Street campus, Ridings said. These plans were initially talked about in June 2013. The mayor’s Office of Neighborhood Services will coordinate the meeting.

All replacement facilities citywide must be made available to the homeless until a new bridge to Long Island is in place. Construction of a new span is expected to take a minimum of 36 months. In December, the mayor’s office announced plans to convert a former city transportation building on Southampton Street into a permanent homeless shelter. That building – which will not be ready for occupancy until next spring— will reportedly house as many as 490 people when completed.
