As the city prepares to host Major League Baseball’s All-Star Game this summer, it’s planning to set up “clean zones” around Target Field and nearby areas.

The idea is to keep private vendors from bringing in their own signs, food and marketing.

The city is considering a resolution requiring approval from MLB before it approves temporary sales, vending, entertainment, signs and related special event permits.

The measure is meant to ensure that the focus of the event is on the fans, athletes, coaches and the game of baseball and “prevent ambush marketing activity and other activities with the potential to detract from the event,” according to the city’s resolution.

The All-Star game is expected to draw about 160,000 visitors to Minneapolis over several days.
