This is current as of January 4, 2014. Check on the Municode web site for the absolute latest information, though it's unlikely that the ordinance will change.
Note that as of 9:30pm January 5, 2014, there is no snow emergency declared for the City of Ann Arbor, but Washtenaw County has declared a "Snow Condition Yellow". From the City of Ann Arbor Facebook:
The City of Ann Arbor is not declaring a snow emergency at this point, but we are recommending residents move their cars off the streets, if possible, to make it easier for city trucks to plow the full width of streets. Moving your car will also keep it from being plowed in with snow.
A snow emergency declared on Dec. 25-26, 2002, but City Council voted in Jan. 6, 2003 to waive or reduce fines from tickets issued during that event; this according to the Ann Arbor Chronicle.
