From time to time I get calls from folks asking why there are yellow, green, blue, etc. lines on their sidewalk or street. Today I looked out my window and saw hot pink lines across my neighbor's driveway. I know about some of the colors but didn't know about the pink.
I called Council Member Crowley's office and her Deputy Chief of Staff Kate Mooney sent me this website. Now we're all a little smarter. LOL
