The Los Angeles Region Planning History Group actively utilizes planning history in the Los Angeles region, including its individual cities, to guide those who are creating its future. The Group promotes the understanding and study of the LA region’s history through programs and conferences, the collection and preservation of major plans, oral and written histories and related documents in planning and related disciplines.
By the late 1970s, the historical legacy of major land use plans and documents for the Los Angeles region was disappearing at an alarming rate. Concerned planners from local agencies, such as the City of Los Angeles and the County of Los Angeles, and archivists from the Huntington Library, gathered informally in the early 1980s to establish a strategy for preservation and education. From these meetings the Los Angeles Region Planning History Group emerged
LARPHG incorporated in 1984 as a nonprofit organization dedicated to preserving municipal, county and private sector planning documents from throughout the Los Angeles region. Over the past 30 years, thousands of documents have been donated to the Huntington Library by the County of Los Angeles, members of the LARPHG Board, and the professional planning community. The following is a summary of where they are described and reproduced.
