The Urbandale City Council approved plans Tuesday for a Knapp Properties Inc. retail development on a little more than two acres near Meredith Drive and Northwest Urbandale Drive. Dan Dutcher, who is a consultant for Knapp Properties, said the company plans to build a 12,000-square-foot building that would have two drive-through bays to launch the project. Construction will not begin until the building is 50 percent leased, he said. Knapp does not have a tenant lined up at this time, Dutcher said. A 7,800-square-foot building is planned for the "hard corner" of Meredith and Northwest Urbandale, he said.
