Visible on clear days from the mainland, Avalon is the only incorporated city on Santa Catalina Island, which sits about 20 miles off the coast of Long Beach.  Serious development of the city began in the early 20th Century when controlling interest in the island was purchased by chewing-gum magnate William Wrigley.  Officially incorporated in 1913, it has been and continues to be a popular tourist destination for more than 100 years.  Avalon boasts numerous hotels, restaurants, botanical gardens, a country club, golf course, beach club, and the Catalina Casino (which despite its name is a former dance hall, not a gambling establishment).  The island is home to over 3,000 permanent residents. The 42nd district covers all of Avalon and Santa Catalina Island. City of Avalon website
