I just had to fight and win against a Pasadena overnight parking ticket because I parked near the border and nobody knew where the border ended or began.

Not only did I receive a ticket, but I even lost the appeal after citing the attached map.

Finally, reached out to a councilmember via email who added some parking dept people and they confirmed I was outside Pasadena’s jurisdiction and cited the exact same map (the one linked here) that I had used as proof during the appeal.

The map is exact, so for example, if it looks like the border divides a street in half, it in fact does. The east side of a street might be Pasadena and west side is LA public works.

Hope this is helpful! Let me know if you need some direct emails to parking enforcement office staff.
