The Vision Iowa board Wednesday awarded just under $2 million in economic development grants to four projects, including the $9.7 million renovation of Cowles Commons, formerly known as Nollen Plaza, in downtown Des Moines. Of $1.9 million awarded by the board, Cowles Commons received $1.1 million. When completed, the public space will act as a fourth stage for Des Moines Performing Arts. Projects in Davenport, Manchester and Harlan also received grants.
