The city of Norwalk had good reason to cheer last week when state and local officials who hold significant titles gathered at the city’s certified industrial site on the south side of town. Folks were bragging, and why not? Two firms, Windsor Windows and Michael Foods, have laid claim to all of the available land, and combined they will add more than 300 jobs and more than $100 million in capital investment. Drive by the site on the west side of Iowa Highway 28 at Delaware Street and it’s an image of industrial build-out. Big buildings, massive amounts of infrastructure. According to a release, this is the first certified site in the state to reach full occupancy.
