The head of a Boston commission that publicly slammed the Wu administration’s handling of a number of hot-button projects and “unprecedented disregard” for state laws that govern its preservation work was fired by the mayor last week.

Rosanne Foley, executive director of the Boston Landmarks Commission, was terminated last Friday, after spending nearly a decade in her post, the Herald has learned, confirming a staffing change first reported by the Dorchester Reporter.

Internal emails obtained by the Herald show that the termination followed the Wu administration’s dissatisfaction with a report submitted by Foley regarding the commission’s efforts to designate Boston City Hall as a landmark — in terms of not incorporating the administration’s suggestions before publicly posting it.

“I can confirm that her last date of employment was last Friday, April 19,” Wu spokesperson Ricardo Patrón said in a Monday email, while declining to confirm or deny that she was fired, saying. “We don’t comment on personnel issues.”

Foley’s termination comes less than two weeks after the Boston Landmarks Commission sent a critical letter to Mayor Michelle Wu with remarks that built on similar remarks made publicly by member and former chair Lynn Smiledge on behalf of the entire commission at a City Council committee hearing in late March.

“We’ve observed over the last year unprecedented disregard by the administration for our legislative mandates, our procedures and our guidelines,” Smiledge said at a March 25 Council committee hearing. “This interference has hampered our ability to fulfill the role that we’ve been legislatively enabled to do.”

An April 9 letter sent by the commission mirrors those remarks, while laying out a number of examples where such “disregard” by the Wu administration has purportedly undermined its historic preservation rights for controversial projects — like the city’s plans to overhaul White Stadium to accommodate a professional women’s soccer team and the board’s effort to designate City Hall as a landmark.

The Commission maintains that since Franklin Park was designated as a Boston landmark in 1980, it must approve all changes to the park, including to White Stadium, but was told it only had purview over part of the project, the letter states.

A group of advocates, after seeing their push for an injunction to stop the proposed White Stadium renovation thrown out by a judge last month, is holding a press conference on Tuesday afternoon to announce “next steps” for their pending lawsuit against the city, mayor and Boston Unity Soccer Partners.

It’s the matter of designating City Hall a Boston landmark that appears to be at the crux of the issue for Foley’s firing, however, according to internal communications between the city’s property management commissioner Eamon Shelton, Foley and Landmarks Commission Chair Bradford Walker, obtained by the Herald.

“The city administration has for several months impeded commission staff by stipulating what aspects of the pending landmark should or should not be included in a study report, which is the backbone of any designation,” the Landmark Commission’s April 9 letter, sent by Walker and signed by all 16 members, states.

Walker notes that only the commission can designate landmarks, but writes, “City administrators have also directed when and how the designation process would proceed, and have stated that they require Commission staff to solicit and coordinate input from various City Hall departments and divisions.”

On March 27, Foley wrote an email directing the included parties to an attached final revision of the City Hall study report, stating that it would be “posted asap” to the Landmark Commission’s April 9 hearing agenda, which was set to be posted two days later, on March 29.

This prompted an email roughly three hours later from Shelton, who requested that he and Foley meet prior to the document being posted, “as it appears many of the major items” that the property management department “commented on were not considered,” and that the departments that would be most impacted by the designation may not been been “adequately consulted.”

Walker, who was copied on the email, wrote back on April 3, stating he took issue with some of the remarks made by Shelton, particularly around the decision to exclude suggestions from the building owner in the final report, which he said the commission is not obligated to do.

Nor is the commission required to consult proactively with the various internal department heads and subdivisions of a particular building’s ownership team, Walker wrote, saying that adhering to such a policy would be “unworkable.”

“The commissioners would like to get this wrapped up and move along, and as chair, I am inclined (to) post the report and place it on the agenda,” Walker wrote. “If the mayor or City Council cannot support the designation, the process makes allowances for their objection.”

On Monday, three days after the dismissal, Shelton sent an email to Walker, pointing to a lack of transparency with how the study report process was handled for what was to be “an unprecedented and drastic expansion” of the City Hall landmark designation.”

“While I appreciate your assurance that all of our concerns were respectfully and carefully regarded, actions taken thus far suggest otherwise,” Shelton wrote. “Conversely, I take issue with the premise of your email regarding the way in which this process has played out.”

Foley, who was appointed by Mayor Marty Walsh in 2015, and Walker did not respond to a request for comment.

Her position fell under the umbrella of the Environment, Energy and Open Space Cabinet, headed by the Rev. Mariama White-Hammond, who departs April 26, and will be replaced by the city’s new chief climate officer, Brian Swett, a move that was announced by the mayor two days before Foley’s termination.

In a statement, Patrón said the Wu administration is reviewing the letter and believes it highlights areas to improve communication and collaboration.

“The shared work of the city and the Landmarks Commission in preserving and promoting the vibrant history and culture of Boston’s neighborhoods is part of what makes the city such a wonderful place for residents and visitors,” Patrón said.
