A very important day for Portland Main Street was held on Aug. 22, 2007. The Main Street program that economically revitalizes traditional downtowns was reviewed by the Michigan State Housing Development Authority (MSHDA). Main Street is a nationally recognized program led by the National Main Street Center.

Currently, there are 13 Michigan Main Street Cities that also undergo the review process. MSHDA and its community assistance team provide trainings, education seminars for Main Street managers and offer guidance for grant opportunities. Communities that apply to become a Main Street wish to reach the goal of becoming a Master Community; a community that uses the Main Street four point approach; Organization, Revitalization, Promotion, and Design to revitalize their downtown.
