Alternate side of the street parking rules will resume on Monday, August 3rd, and will be in effect through Saturday, September 5th.
When alternate side parking is in effect, residential side streets that have multiple alternate side parking days will be cleaned--with vehicles required to be moved--only on the latest day in the week on each side, through Labor Day.
