    Historical Note

    The planning history of Los Angeles can be traced to September 4, 1781, when Spanish Governor of the Californias Felipe de Neve founded El Pueblo de Nuestra Señora la Reina de los Ángeles. At the time, planning efforts were mostly simple instructions on the placement of houses and buildings. During the area’s subsequent growth and changes in governing bodies, many planning actions were implemented in limited scope. It was not till early twentieth-century when planners started to give serious thought on preparing the city for future economic and population growth. The use of zoning regulation was first attempted in Los Angeles in 1904, as the ordinance called for the creation of a residential district. In 1908 two new ordinances were implemented to divide the entire city into industrial and residential districts. When the ordinances were contested by a brick manufacturer in 1915, the United States Supreme Court ruled in Hadacheck v. Sebastian in favor of the City, upholding the constitutionality of zoning regulations. In March 1920 the City of Los Angeles adopted a commission ordinance that was drafted by G. Gordon Whitnall. The ordinance appointed a 51-member advisory planning commission to guide the city’s future growth. As consultant-secretary of the planning commission, Whitnall also played a prominent role in the formation of the Los Angeles County Regional Planning Commission, which was formed in 1922 to advise the Board of Supervisors on all planning issues.
