Which city does the fictional American television sitcom family the Cleavers of “Leave it to Beaver” live in?

"Leave It to Beaver" is an American television sitcom broadcast between 1957 and 1963 about an inquisitive and often naïve boy, Theodore "The Beaver" Cleaver (Jerry Mathers), and his adventures at home, school, and around his suburban neighborhood. The show also starred Barbara Billingsley and Hugh Beaumont as Beaver's parents, June and Ward Cleaver, and Tony Dow as Beaver's brother Wally. The show has attained an iconic status in the United States, with the Cleavers exemplifying the idealized suburban family of the mid-20th century.

The Cleavers live in the fictional town of Mayfield. Ward is a white-collar, brief case-toting professional; he states he is an engineer who had experience as a Seabee. June is a full-time homemaker. In the second season, Wally is a high-school student.

Being five years older than the Beaver, he often acts as a bridge between his parents and his brother. He puts communications from the parents into kidspeak for the Beaver and keeps his parents apprised of the Beaver's plans, feelings, and activities.

The Cleavers dwell in a spacious house on Mapleton Drive during the first two seasons. They moved to a similar house on nearby Pine Street for the remaining four seasons. The family drives a 1957 Ford Custom 300 in the first two seasons. In the remaining seasons, when the Chrysler Corporation was a sponsor of the program, the family car is a Plymouth Belvedere or a Plymouth Fury.
