Richmond extends across a varied East Bay shoreline, from San Francisco Bay waterfront districts toward San Pablo Bay. Marina Bay, Point Richmond, industrial areas, and inland neighborhoods create several distinct urban landscapes within one city. Marina Bay's public waterfront and landscaped areas offer a civic counterpoint to Richmond's working shoreline. Richmond City Hall at Civic Center Plaza anchors municipal services away from the marina district. Richmond incorporated on August 7, 1905. It is a charter city operating under council-manager government.
