At any time during the year it is not wise to park on down town streets during the night. Street cleaning operations take place on the city's main streets during the early morning hours (usually between midnight and 8am) and in residential areas between 8am and 4pm. You could be ticketed or towed by a very expensive professional contractor. In order for the city to do its' job proper and get the job done in a reasonable time, you must not impede their progress. Every time they have to call for the tow truck it sets them back (at least) 1/2 hr which wastes precious tax dollars used to perform this needed operation as they wait for the vehicle to be moved or return to redo the area.
Often, when time is short or the budget is low, the tow truck is not called. In winter months, parking during cleaning operations can create bad hazards for other drivers when you do leave. Patches of snow remain after plowing that turn into packed ice and when it snows again (it takes about 4 days to clean all the city streets after a dump of snow) it becomes extremely slippery after more snow builds up on it. Street sweepers leave a patch of dust that they may not pick up for a month or more after they finish the street. The patch grows as the dust collects between cleaning operations and adds to our bad air quality.
