Predominantly from the 1970s, the records of the Northridge Civic Association document the successful and unsuccessful stands the organization took on local development and quality of life concerns, especially zone changes and street widening. The views of the group are officially represented in testimonies presented during public hearings before the Los Angeles City Planning Department and the City Council. The majority of the papers are from former president Dorothy Boberg's files and contain correspondence, newspaper clippings, proposals, reports and research notes. A small addition of records was processed separately and added to the collection in 1989. Copies of various community plans for the San Fernando Valley are also contained in the collection. The organization obtained the plans to be familiar with the city's objectives in local urban development. The collection has been arranged in four series: Administrative Records (1958-2006), Correspondence (1970-1982), Subject Files (1951-2002), and Non-Manuscript Material (1964-1998).

Series I, Administrative Records, documents the activities and concerns of the Northridge Civic Association. A copy of the original by-laws in 1958 is followed by a nine year gap in the files. Coinciding with Dorothy Boberg's involvement in the organization in 1967, a more precise description of the association is illustrated in meeting agendas and minutes, press releases, reports, membership lists, and a small scrapbook of newspaper clippings pertaining to the organization. Files are arranged alphabetically and chronological within.

Series II, Correspondence, contains correspondence documenting the civic association’s primary focus areas. Many of Dorothy Boberg's research notes and several of her testimonies are also contained in this series. Files are arranged alphabetically and chronological within.

Series III, Subject Files, is comprised of the topics and issues of concern to both Dorothy Boberg and the Northridge Civic Association as they affected Northridge and other local communities. Predominantly from the late 1960s through the 1970s, these files include information on development plans for the area, preservation issues, and numerous accounts of zoning changes. The main subjects are filed alphabetically and chronological within.

Series IV, Oversize and Non-Manuscript Material, consists of 42 maps, 16 newspaper clippings, 53 photographs, and 5 volumes of reports.
