Donald Shoup, distinguished research professor of urban planning, was mentioned in a New York Times opinion piece about the hidden consequences of parking requirements. In his book “The High Cost of Free Parking,” Shoup explained that rules that require developers to include a minimum number of parking spaces increase real estate costs. Furthermore, building more parking lots creates more urban sprawl, making cities less walkable and more car-dependent. Parking lots also exacerbate the effects of global warming by creating urban heat islands that absorb and reflect heat. Shoup has also noted that parking requirements worsen inequality by forcing people who can’t afford to drive a car to still pay for parking infrastructure. “People who are too poor to own a car pay more for their groceries to ensure that richer people can park free when they drive to the store,” Shoup wrote. Now, California is considering legislation that would eliminate or reform minimum parking regulations.
