The Iowa Economic Development Authority Thursday also awarded $1 million in Main Street Iowa Challenge Grants to 14 communities around the state. The grants will benefit local improvement projects, including upper story renovations, critical building stabilization and façade restoration and upgrades. The grants are administered through IEDA’s Iowa Downtown Resource Center and Main Street Iowa programs. The funding will be distributed in the form of matching grants to the selected Main Street programs. The estimated total project cost of these 14 projects is over $3.2 million. In southeast Iowa both Ottumwa and Centerville’s Main Street organizations were awarded $75,000. Since the first Challenge Grants were awarded in 2002, approximately $10.6 million in state and federal funds have leveraged more than $59 million in private investment. Over the life of the program, 179 projects in 54 Main Street Iowa commercial districts across the state have received funding.
