Answer:
The development of new cities-Louisville, Cincinnati, St. Louis, and Buffalo-away from the Atlantic coast was possible because they had access rivers that made it easy for them to trade.
Zoning ordinances are a good example. A territory is divided in commercial, industrial and residential zones. A business cannot be built or established in a residential zone. Environmental laws and regulations are another example. Industries cannot (at least not according to the law) dump toxic, dangerous waste from their property. They have to remove toxic materials from their buildings such as asbestos.
