Who is a local government type that is most like that of the federal government?

A local government type that is most like that of the federal government is a city or municipal government structured as a mayor-council system. In this setup, the mayor serves as the executive, similar to the president at the federal level, while the city council acts as the legislative body, akin to Congress. This structure allows for a separation of powers and provides a framework for governance that mirrors the federal system. Additionally, it often includes various departments and agencies, further resembling the federal government's organization.
