Good government is not just the responsibility of city officials and employees: citizens and residents also play an important role. The city has almost 70 boards and commissions that include citizens and residents. These individuals devote their energy, time and expertise to make Phoenix a better place for everyone. Aviation, Historic Preservation, Planning, Transportation, Parks and Recreation and Human Services are some of the departments that benefit from boards and commissions. This section describes in more detail the various boards and the application process. Please note that some boards require residency within the city of Phoenix.
