Pilot program testing new process for reviewing alterations to possible Rochester landmarks moves ahead The pilot program will focus on a developer's proposed plan to renovate the Olmsted County Bank and Trust building. Posted: May 24, 2021 10:30 PM ROCHESTER, Minn. - Local leaders will test out a new way of reviewing proposed changes to possible historic landmarks in the Med City. The Rochester City Council has approved a pilot program allowing the city's Heritage Preservation Commission to approve or deny a developer's plan to renovate the Olmsted County Bank and Trust building without a typically required permit. The developer will instead seek a "certificate of appropriateness" from the HPC and apply for necessary permits separately.
