A formal joining of a city (or cities) with a surrounding county government is called a city-county consolidation. The resulting unified body assumes the responsibilities of both the city and the county. Although city-county consolidation has been the most widely attempted metropolitan reorganization model, the Census Bureau identifies only 34 city-county consolidated governments out of a total of 3,069 county governments. For a list, see Consolidated City-County Governments.
While city-county consolidations are rare, there have been many state and local initiatives attempting consolidation. The rationale for consolidation is to address certain government challenges. Consolidations have the potential to do the following:
Almost every state has provisions in general law to change local government boundaries through municipal annexation or incorporation, but few states permit city-county consolidation in general law. In most places, a majority of citizens must pass a referendum before it can be approved by the state legislature: once the issue becomes part of the local public agenda and petitions and studies have been completed, a commission drafts a new charter. After the referendum, the proposed charter will be ratified or rejected.
Over the last 40 years, nearly 100 referenda and initiatives have proposed city-county consolidations, but voters have rejected three-fourths of them. Multiple attempts at consolidation are typically necessary. In Georgia, for instance, it took 20 years for two consolidations to take place. Georgia voters repeatedly defeated the measures. Across the nation in the 1990s, only six out of 20 attempts were successful. Some consolidations fill a need for a basic service and occur where there are a small number of incorporated suburbs. Despite continued interest in consolidations, there are simpler and less controversial ways to achieve the objectives, such as annexations, special districts or the formation of new municipal governments.
The government charter of a consolidated government defines its structure and is based on the local context. The "pure model" involves the combination of several municipalities and a county government in a metropolitan area into a single government. In this model, two distinct service districts may also be created, with one to provide services for the urban population and another for the rural population. In this case, taxation is linked to the level of services provided. In practice, however, most consolidation efforts do not result in only one government; often small municipalities, special districts and autonomous authorities and boards (for example, health, hospital, the school board, planning board, the port, the electric authority) continue to operate. It is also possible that certain incorporated jurisdictions within the new boundary lines may opt to be excluded.
The most common form of consolidated government is a single chief executive and a multi-district council with a few at-large seats. The executive, or mayor, has veto power, while the council has both legislative and fiscal functions. Occasionally a city manager is appointed.
