Mililani is a city located near the center of the island of Oahu in Honolulu County, Hawaii, United States. It consists of two census-designated places, Mililani Town, with a population of 27,629 at the 2010 census, and Mililani Mauka, with a 2010 census population of 21,039. Mililani sits on former plantation fields owned by Castle & Cooke, which began planning for its development in the early 1960s under its Oceanic Properties subsidiary. Castle & Cooke's plan was to make Mililani Town a satellite city by using a prestigious group of planners and architects to satisfy Oahu's great pent-up demand for housing with a sensitively designed, affordable new community of a type unique in Hawaii. Architect and developer Al Boeke, who would later create the planned community of Sea Ranch, California, was the development director of Mililani. The first homes in Mililani went on sale on June 3, 1968.
Mililani was named an All-America City. It is the only community in Hawaii ever to receive this distinction. Mililani is the third wealthiest zip code (96789) in the state of Hawaii. Although it is largely a bedroom community for Honolulu, Mililani has its own commercial shopping centers, schools, parks, community centers, and a golf course, and resembles a modern American suburban town. Mililani homeowners must pay dues to the Mililani Town Association, which enforces covenants and design standards, and provides recreational facilities including several pools and recreation areas. The community is very family oriented and many merchants offer discounts and the town has many family events to attend year round.
Joint Base Hickam-Schofield Barracks is just down the road from Mililani and just beyond that town of Wahiawa is the North Shore.
