Independent special districts are sanctioned under California Law for the performance of local governmental functions within specified boundaries. Agencies range in size from small to very large and often cross political boundary lines, such as city and county borders, to serve a common community of interest. There is a clear identification between agency name and services provided, which has resulted in a high level of accountability and responsibility to the public, and a high degree of customer satisfaction. As such, they are an integral part of local government and contribute significantly to the quality of life in the communities they serve.
