The address is 271, not 273.

I feel your pain! I have the same problem but parking enforcement does come out and they give tickets to the offenders. Hang in there.

LAST RESORT IS THE POLICE

What's the point ? I call the Police, they tell me to call Parking Authority. I call Parking Authority, WHEN they do come, is usually WAY after the fact and the person blocking the driveway is already gone. So I tried using using this APP, but, just another vicious circle. So, the people can keep parking where they want, I can keep complaining and NOTHING will happen. Gee, if the Mayor lived in my area, would this be an issue ??? "SeeClickFix", thanks for taking care of another issue (Yea, that was very sarcastic).
