Where Not to Park in San Francisco
SFGate, the website of the San Francisco Chronicle, has created this Google Map showing locations with 100 or more parking citations in the city. You can get more cartographic data visiting georeferenced pdf vector map of San Francisco, California, US, Adobe Illustrator.
The number of citations are indicated by the size of marker, the bigger the bubble on the map, the bigger the number of citations issued. Users can click on a bubble to see the number of citations issued at that location. My advice is not to park at 50 Phelan Ave, which has seen nearly 4,000 citations issued in the last year.
