"No sizable city in the country, or likely the world, has been able to say with any certainty how many parking spaces it has, public or private, until now. Over the last 18 months, the San Francisco Municipal Transportation Agency (MTA) has tallied every publicly accessible parking space within city limits, including free and metered spaces on-street and every publicly accessible garage [PDF map].
The total number of spaces, as Mayor Gavin Newsom recently announced on his Youtube site, is 441,541. Of the total, over 280,000 are on-street spaces, 25,000 of which are metered. For just the on-street spaces, that is roughly the equivalent area of Golden Gate Park."
Streetsblog reports on the parking Census and give a look into how that data may be used to help solve the city's mobility and congestion issues.
