NOTICE
The four parking garages for Mansfield Towers will be closed at various times during the last three weeks of June for cleaning and repainting. Please make alternative arrangements for parking during this period. Make sure to inform the receptionist in the lobby if you are expecting clients from out of town in June. We will issue temporary parking passes for the garage at 5th and Main for our clients. These passes can be purchased for a fee of $2.00 a day during the month of June, but are reserved for regular clients, not employees. There are five spots available for these clients, and these will be assigned on a reservation basis only. Note: Parking on Green St. or Howe Ave. is strictly prohibited. Cars that are illegally parked will be ticketed and towed. For information about other local parking garages call the city help line at 800-555-9000.
