The overall goal of the Central Tualatin Overlay Zone is to strengthen the social and economic development of central Tualatin; encourage and facilitate land uses, private and public, that result in activity during all business hours, evenings, nights, and weekends; and to encourage indoor and outdoor uses. The overlay zone regulations are intended to ensure development contributes towards these goals.
