Is the 100-Foot Parking Law Real?

100 Foot Law

Dear Parking Guru,
I just received a ticket for a street-sweeping sign that was way up the street from where I parked. I went to the library that day and found your book. In it, you say that, “The 100 foot law states that...each restrictive parking sign's enforcement zone extends for 100 feet in each direction, or up to the nearest cross-street, whichever is less. The only reasonable argument I can see for having a parking ticket dismissed would be that there is no sign posted anywhere in the City that warns us of this.” Where is this law 100-foot law written?

On-Street Car Sharing, Coming Soon to SF

As early as January 2014, San Francisco will undergo a wonderful two-year experiment that I think is going to be a major success in what I like to call the sustainable urban mobility movement.

Woman Receives Parking Ticket for Attempted Violation of the Law of Inertia


Dear Parking Guru,

I often feel lucky to find parking at all in SF. Last week I did, but then it was all ruined because when I returned to my car I found a ticket on my windshield. I am a victim for an issued citation for "parking on grades." 

What Would Life Be Without BART?

With this week’s BART strike, everything involving cars and car-related revenue has increased: Casual and formal carpool usage has increased; bridge toll revenue has increased; rental car revenue has increased; parking garage revenue has increased; parking meter revenue has increased; and with more drivers, (many unfamiliar with the ins and outs of City parking) and fewer spots available, parking ticket revenue and towed car revenue have increased.

What Would It Take to Get Humans to Change Their Ways and Save the Planet?

While doing my morning number crunching and parking efficiency algorithmic warm-up exercises, I came upon a staggering statistic about parking.  

Playing Dice with the Parking Gods

Parking Guru

Dear Parking Guru,
I just know you have a solution for me. I am new to SF and live in the Haight and feel so happy to be here. I have a problem though, and in googling for a solution, you kept popping up. I live in a place with a driveway and I found out that I am allowed to block my own driveway when parking parallel on the street. The problem is that on both sides of it are those on-street spots where the curb isn’t long enough for a regular car to park. The driveway is narrow, so when I park in my driveway part of my car sticks into one or both of these “half” spots.

Parking and Traffic Number Crunching: Part 2

A couple of weeks ago I posted the some of the highlights of the most recent San Francisco transportation numbers.

I’ve received more than a few requests for more numbers, so here is SFMTA Greatest Hits, the B-Sides:

Changing Global Warming, One Parking Spot at a Time

There are currently 1.2 billion cows on the planet. Naturally, I wondered how much environmental impact they are having. A Japanese study showed that producing a kilogram of beef leads to the emission of greenhouse gases with a global warming potential equivalent to 36.4 kilograms of carbon dioxide (CO2). I then wondered how this compared to parking.

Parking Karma, App(titude), or Luck?

Earlier this week I found myself once again driving to a tech meeting, cutting the time way too close. So little time, so much to be done, and each day, it seems, the show must go on and somehow I get everything done. But, I digress.
