If you believe you have been improperly ticketed for a parking violation, and would like a hearing, you have two options:
Hearing by mail
Mail a copy of the ticket along with a signed operator statement and any supporting documentation to Traffic and Parking 133 Holland Avenue, Somerville, MA 02144. Dispositions will be returned within 21 days of receipt.
Hearing in Person
A hearing will automatically be scheduled for any violations if not paid in full within 21 days. You will receive an overdue and hearing notice approximately 45 days after the issue date of the ticket.
According to the Parking Office, who I have just visited today, that's pretty much true, except that that the "21 days" in the first section is actually "90 days". All the other deadlines are the same. You see the problem?
