I have a ticket. You can pay the original fee if paid within ten days. After ten days, the amount increases and continues to do so every ten days. After forty days, it goes to collections and may incur additional late fees, collection agency fees, or court costs. Please follow the instructions on the back of your parking ticket.
More information is available there.
You have the right to appeal any ticket, either in writing, over the fax machine, by email, or in person.
