Axios Des Moines: Food trucks are now allowed on Des Moines’ streets during special events under a new rule approved by the City Council this week. Ordinances had limited the trucks to specific zones and parks. The ordinance change was prompted by the Des Moines Heritage Center, a downtown events venue at a historic depot. It’s located just outside of zones that allow food trucks and that was limiting its options. Special event permits now allow food trucks to operate on public streets in commercial or mixed-use locations that are outside of the zones.
