You cannot sweep dirt from your store into the street.

The Law Explained

To keep the city streets of Fargo looking clean and respectable, an old ordinance mandated that business owners dispose of their floor sweepings properly rather than just pushing dust out the front door. Before motorized street sweepers, this lazy habit created massive dust clouds and filthy sidewalks for pedestrians. Shopkeepers had to invest in dustpans or face a municipal fine.
