Matthew Cordau, the architect of record for 370 Main Street, told the Historic District and Landmark Preservation Commission that the team’s submitted application covered interior alterations, but both planning staff and commissioners said the city’s site‑plan review for a proposed change of use will trigger review of the exterior façade and advise a preservation approach for the building’s historic terracotta elements.

Cordau said the project’s immediate scope is interior work and that he had expected to address terracotta restoration at a later stage. “Our application was originally for an interior alteration, but it was recommended by the city that we, do an exterior preservation project on the building,” he told the commission, and added that he would circle back to the client and present a preservation plan.

Commissioners and staff told the architect that if the project proceeds with a site‑plan or special‑use review, the façade condition — including glazing and deteriorated terracotta and gilded lettering — must be addressed as part of the approval pathway. Staff advised the applicant to supplement the HDLPC application with proposed methods of terracotta repair or a master plan that sequences exterior stabilization and restoration.

The HDLPC adjourned 370 Main Street to the commission’s September meeting to allow the applicant to return with a defined scope for façade restoration or a preservation plan that coordinates with forthcoming site‑plan review. The commission emphasized that the application package should include proposed façade repair methods and documentation of safety‑stabilization measures already completed.

Less critical details: Cordau apologized for presenting without exterior drawings and said he will coordinate with his client and return; the commission noted that a supplemental application should define the terracotta method of repair and that staff will expect the façade to be part of site‑plan approvals.
