This section is designed to provide local officials with an overview of metropolitan planning organizations – regional agencies governed by local officials within their metropolitan region. These agencies have important responsibilities, including a new emphasis on regional planning for transportation and housing as revised by SB 375. Below is information on regional planning activities (including the development of sustainable communities strategies), public participation efforts and planning documents for each metropolitan planning organization.
