The city needs to have a system for plowing BOTH sides of residential streets. After the first odd-side parking ban, and plowing of the odd side of the street, the next step should be an EVEN side parking ban, and cleaning the EVEN side.
Alternate side of the street snow removal is typical in cities, and has been the norm in all the northern cities and towns where I have lived.
New Haven's odd approach means that after a big snowfall, if there is a second storm residents can't park on the even side of the street, because it is blocked with huge mounds of snow. If the city never removes the snow after each storm, things become more difficult with each storm.
Why doesn't New Haven follow a logical system to guarantee clear streets during the winter?
