Charter city
In the United States, a charter city is a city in which the governing system is defined by the city's own charter document rather than by state, provincial, regional or national laws. In locations where city charters are allowed by law, a city can adopt or modify its organizing charter by decision of its administration by the way established in the charter. These cities may be administered predominantly by residents or through a third-party management structure, because a charter gives a city the flexibility to choose novel types of government structure. Charter cities are similar in administrative structure to special administrative regions.
Examples
For example, in California, cities which have not adopted a charter are organized by state law. Such a city is called a General Law City, which will be managed by a 5-member city council. A city organized under a charter may choose different systems, including the "strong mayor" or "city manager" forms of government. As of June 2008, 112 of California's 478 cities are charter cities. A few examples include Newport Beach, Palo Alto, Huntington Beach, San Bernardino, Irvine, Los Angeles, and the capital, Sacramento. However, charter cities that are subordinate to the rules of larger institutions (such as provinces or nations) have limited flexibility to adopt new governance structures.
