Downtown Maryville
In 2014, the City of Maryville authorized a resolution of support and funding for the Maryville Downtown Improvement Organization, Inc. (MDIO) endorsing their application to the Missouri Main Street Program's Affiliate Grant. MDIO was approved as an Affiliate Community in the Missouri Main Street Program and now serves as the catalyst for downtown revitalization.
