alternate- side- of- the- street parking. System of regulations imposed in 1950 that limits curbside parking to one side of the street on certain days of the week. The regulations began as an experiment on the Lower East Side to facilitate street cleaning, which had recently become mechanized, and were soon extended to all of Manhattan, the Bronx, Brooklyn, and Queens. In many areas parking was allowed only on the south side of the street during three- hour periods on Mondays, Wednesdays, and Fridays, and only on the north side during three- hour periods on Tuesdays, Thursdays, and Saturdays. Fines levied against violators were at fi rst nominal but increased as the city began to rely more heavily on parking tickets as a source of revenue: by 2008 the fi ne for alternate- side- of- thestreet violations reached $65 and receipts from parking citations of all kinds exceeded $550 million. More than 10,000 miles (16,000 kilometers) of street fell under alternate- sideof- the- street rules. Motorists, in what some sarcastically refer to as the “New York Grand Prix,” ritualistically moved their vehicles each morning from one side of the street to the other, often just ahead of the street cleaners. In 2001 Calvin Trillin published Tepper Isn’t Going Out, a humorous novel about a man who found the perfect parking spot and decided to stay in his car forever. Initially the regulations were suspended only on Sundays and civic holidays such as Veterans Day, but in 1952 the City Council added the Jewish high holy days, with Catholic holy days following soon after. Greek Orthodox holy days were added in 1990. In more recent years the number of suspended days has grown to 34 with the addition of Muslim (Idul- Fitr and Eid al- Adha) and Hindu (Divali) holy days and the Asian Lunar New Year. The regulations are also routinely suspended after heavy snowfalls. The high fi nes and seemingly greater competition for a fi xed number of parking spaces have given rise to several thriving businesses that offer car- moving and ticket- fi xing ser vices.
