This collection contains 17 atlases (in 16 volumes) of land use maps for areas in Los Angeles County, California, made between 1936 and 1939. The maps were created by the Regional Planning Commission of the County of Los Angeles in conjunction with the Work Projects Administration (WPA) for use in preparing the County's Master Plan of Land Use.

The Los Angeles County Regional Planning Commission was formed in 1922 to advise the Board of Supervisors on all planning issues. In January 1936, the Federal Work Projects Administration, under the sponsorship of the Regional Planning Commission, began conducting a survey of natural land types and existing land cover and use in the Los Angeles metropolitan area, to facilitate the creation of a Master Plan of Land Use, as required by the 1937 California Planning Act. The survey was completed in July 1940 and culminated in volumes of colored maps, charts, and tables, and land use reports and recommendations.
