The City of Los Angeles generally prohibits freeway, supergraphic and off-site billboards, but has adopted a few exceptions to the rule. For instance, it permits freeway signs and supergraphic and off-site signs in areas where specific plans are adopted to govern such signs or pursuant to development agreements, in accordance with its police power (the power to control local land use). Numerous billboard companies erected freeway and supergraphic signs all over the city. In 2008, the city adopted a moratorium on new supergraphic and off-site signs.
