The Past, Present, and Future of Parking: a Case Study of Metropolitan Phoenix, Arizona

There is relatively little knowledge of how much parking infrastructure exists despite mounting evidence that abundant and underpriced parking creates land use, economic, environmental, and social problems. Urban parking requirements are very precise, regularly developed, and regularly updated despite the fact that most cities have little to no knowledge about their own parking supply. To further explore this issue, a parking inventory for metropolitan Phoenix, Arizona is developed by cross-referencing geospatial cadastral and roadway data with minimum parking requirements. Historical growth of parking is also estimated by assigning the year of property development to required off-street and nearby on-street parking spaces. The authors estimate there are 12.2 million spaces in metro Phoenix with over 4 spaces per vehicle, over 3 spaces per person, and nearly 7 spaces per job. Growth of parking infrastructure in metro Phoenix has also been significant; 11 million spaces have been added to the region since 1960. Since the 2008 recession, parking growth in metro Phoenix has significantly slowed, but continued trends of urban growth combined with unchanged minimum parking requirements may promote parking infrastructure to be built at an oversupplied rate. Planners and policy makers, especially in hot and sprawling regions like metro Phoenix, should value quantifying the supply of parking in urban areas and consider reforming parking standards to promote sustainable urban growth.
