As mayor, Brown was criticized for aggregating power and favoring certain business interests at the city's expense as a whole. Supporters point to the many development projects completed or planned under his watch, including the restoration of City Hall and historic waterfront buildings; the setting in motion of one of the city's largest ever mixed-use development projects in Mission Bay, and the development of a second campus for the University of California, San Francisco. In contrast, critics objected to the construction of many live-work loft buildings in formerly working-class neighborhoods that they believed led to gentrification and displacement of residents and light industry.
