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 high-water mark for American parking policy came in the early 1970s, when cities including New York, Boston, and Portland set limits on off-street parking in their downtowns. They were compelled to do so by lawsuits brought under the Clean Air Act, which used the lever of parking policy to curb traffic and reduce pollution from auto emissions. This level of innovation went unmatched over the ensuing three-and-a-half decades. Only now are American cities implementing effective new parking strategies that cut down on traffic.

The recommendations in the MTA's new parking study, which Streetsblog reported on yesterday, are designed to make it easier for customers to find a place to park when they visit businesses on evenings and Sundays. The study comprehensively examines the demand for parking in all of the city's major commercial districts, aiming to extend meter hours only when and where demand overwhelms the number of available spots. If the MTA doesn't act quickly and strategically to sell the changes to businesses, however, the study's great promise could be overwhelmed by protests from merchants who don't yet see how the plan will benefit them.

Mayor Gavin Newsom has been quietly pressuring MTA Chief Nat Ford to delay or prevent proposals to extend parking meter hours on weeknights and Sundays, despite a looming mid-year MTA budget deficit and studies that show it's good policy, Streetsblog has learned.

If the recent parking battle in Oakland had you thinking of UCLA Professor Donald Shoup, you're not alone.

An anonymous photographer snapped the above photo last Wednesday on Terry Francois Boulevard, across from AT&T Park, where SFpark electronic meters were recently installed. It seems one driver got the wacky idea that the new meters require cars to park perpendicularly, across the bike lanes, and the other drivers followed?

The San Francisco County Transportation Authority (TA) presented the results of the comprehensive parking study it started in 2006 to the Board of Supervisors today, fleshing out many of the parking management principles espoused by parking guru Donald Shoup in his High Cost of Free Parking and recommending a plethora of solutions for managing the curb more strategically (presentation PDF).
