Since 1986, the city of Phoenix has been divided into urban villages, many of which are based upon historically significant neighborhoods and communities. Each village has a planning committee. This committee is appointed directly by the city council. According to the village planning handbook issued by the city, the purpose of the village planning committees is to work with the city's planning commission to ensure a balance of housing and employment in each village. The committees also concentrate on development at identified village cores, and to promote the unique character and identity of the villages.
