Commission members reported they had met informally to begin drafting updates to Chapter 31 that would allow certain exterior materials on historic structures that meet design standards and improve energy efficiency. The chair reported the working group — which included members identified only by first name — will present suggested changes for formal consideration at the commission’s next meeting in September.

The commission member who raised the matter said the group reviewed the 2025 work plan and discussed permitting exterior materials that satisfy both historic-appearance standards and energy-efficiency goals. No formal proposal or vote was taken; commissioners said the topic will return to a future agenda for detailed review and public discussion.

Staff noted the matter was not ready for full agenda consideration this month and that a formal staff memorandum and draft ordinance language will be prepared for the next meeting. Commissioners thanked the small working group for its initial review and scheduled continued discussion at the September meeting.
