Parking eats up an incredible amount of space and costs America’s cities an extraordinary amount of money. That’s the main takeaway of a new study that looks in detail at parking in five U.S. cities: New York, Philadelphia, Seattle, Des Moines, and Jackson, Wyoming.
The study, by Eric Scharnhorst of the Research Institute for Housing America (which is affiliated with the Mortgage Bankers of America), uses data from satellite images, the U.S. Census, property tax assessment offices, city departments of transportation, parking authorities, and geospatial maps like Google Maps to generate inventories of parking for these five cities. (The inventories include on-street parking spaces, off-street surface parking lots, and off-street parking structures.)
It not only estimates the total number of parking spaces in these cities and their overall estimated replacement costs, but develops interesting metrics such as parking spaces per acre, parking spaces per household, and parking costs per household—as well as providing maps of parking densities across these cities.
