But a new segment from David Stevenson — KTVU’s helmetless heathen hunter himself — quickly descends into incoherence, arguing that parking spaces in San Francisco are being eliminated at a drastic rate because of parklets, bike lanes, housing, and other things that are certainly less important than car storage.
Amidst the breathless barrage of shoddy reporting, this is probably the most disingenuous part:
As far back as 2006, the city used a formula to estimate 603,000 public and private parking spaces on the streets, in lots and garages.
But that number was downsized to 448,000 in 2012 after a sweeping citywide parking space survey.
To the uninitiated, this probably seems like the city has lost a quarter of its parking, but of course it only indicates that the city has recently started to measure its parking supply more rigorously. The 2006 estimate was basically just a guess, while the latest number was based on an actual citywide count of parking spaces done in 2010 (the first of its kind in the country), then updated in August 2011 with a survey of 54 percent of SF’s streets [PDF].
What Stevenson doesn’t mention at all is that the formula and the count didn’t even measure the same thing: The 2006 estimate included all parking, private and public, while the more recent counts have only measured publicly accessible spaces. As Matthew Roth noted in his Streetsblog article on the SFMTA’s massive 2010 public parking count, the city’s private parking supply hasn’t been comprehensively measured yet, but experts estimate it could bring the citywide supply as high as 800,000 (nearly one parking space per San Franciscan).
A full accounting of the city’s changing parking supply would also factor in the continuing construction of off-street parking. Parking is constantly being added in the course of development — just yesterday, the Planning Commission approved a grocery store and 136-unit development in Hayes Valley with 275 parking spots. The net change in parking spaces that results from those developments depends on how much parking those buildings replace and how much is being constructed.
