From a City of Madison News Release:
Beginning Monday, January 28, 2008, the Parking Utility will not charge for parking in cashiered sections of city garages between 9 p.m. and 7 a.m. on declared snow emergency days.
Parkers will need to pay for parking before 9 p.m. or after 7 a.m. on those days.
These new times will take affect immediately at the following facilities: Government East, Overture Center, State Street Campus, State Street Capitol and Capitol Square North. It is not available at other Parking Utility facilities.
By expanding these parking hours during snow emergencies, the City hopes that there will be fewer parked vehicles on public streets, which would help facilitate snow removal during heavy snowfalls.
