SALT LAKE CITY (KTVX) — Nearly one-third of downtown Salt Lake City is dedicated solely to car parking, according to data released by a nonprofit last week. And Salt Lake is far from alone. In Wichita, it’s 35%. In Las Vegas, it’s 32%. In San Bernardino, it’s even worse: 49% of the central city is composed of parking.

The data comes from the Parking Reform Network, an organization that works to inform people about the impact of parking on climate change, housing, traffic and more. The group has published 86 maps of cities across the United States, highlighting the space dedicated to parking lots in city centers.

On average, in U.S. cities with over 1 million people, 22% of land in the city center is used for parking.

Take a look at Salt Lake City, for example. About 29% of downtown is highlighted red, which represents an area that is a designated parking lot. The city even has a few parking structures that span entire blocks.

Many of the maps created by Parking Reform Network look similar, from Colorado Springs to Jacksonville, Florida.

Parking Reform Network argues that space could be better used for housing, businesses, or public gathering spaces.

“This parking is often clustered around main streets, office districts, and historical cores, creating a dead zone around the city’s most valuable and walkable areas that limits residential and commercial growth. Cities with high parking have ample land that could be devoted to building walkable neighborhoods, vibrant parks, or office districts,” the group writes.

Compare the map of Salt Lake City to New York’s core (where only 1% of space is dedicated to parking lots), or Boston, where 6% is parking.

Of the cities analyzed, those who had the most space dedicated to parking were San Bernardino, California (49%); Arlington, Texas (42%); Lexington, Kentucky (38%); Wichita, Kansas (35%); and Virginia Beach (35%).

New York City (1%), Washington DC (3%), Chicago (4%), San Francisco (4%) and Boston (6%) were found to be the top five city centers with the least amount of dedicated parking spaces.

Because their analysis focuses on how land is being used, Parking Reform Network did not include underground parking garages from their calculations.
