The Iowa Economic Development Authority has awarded $930,808 in Main Street Iowa Challenge Grants to 10 Iowa communities. The grants, administered through IEDA’s Iowa Downtown Resource Center and Main Street Iowa programs, help redevelop or rehabilitate underused buildings on Iowa’s main streets, a news release said. The funding will be distributed in the form of matching grants to the selected Main Street programs. The estimated total cost of the 10 projects is more than $3.3 million, according to the release. “This investment in downtown revitalization projects often creates a ripple effect, building momentum that inspires further collaboration and development,” said Jim Engle, director of the Iowa Downtown Resource Center, in a prepared statement. “Transforming community centers back into vibrant hubs of activity drives significant economic impact and enhances the quality of life for Iowans who live there.”
