A Governing article on California’s move away from policies that promote car-oriented communities cited Donald Shoup, the distinguished research professor of urban planning who has spent his career studying the social, economic and environmental impact of parking policies. Shoup, author of the seminal 2005 book “The High Cost of Free Parking,” has long argued that rules mandating excess parking in new development projects add to the overlapping crises of housing affordability, urban sprawl and climate change. Influenced by Shoup’s work, cities from Buffalo to Minneapolis to San Diego have begun reducing or eliminating some of their minimum parking requirements. A new bill in California, which awaits the signature of Gov. Gavin Newsom, would be a substantial acceleration of that trend — and a remarkable capstone to Shoup’s academic career, the article noted. “It’s only been 50 years,” Shoup said. “It makes me feel grateful for longevity.”
