This series documents the newly-formed CCSEP's efforts to block the City Council's proposal to build a new Los Angeles Convention Center in the heart of Elysian Park near the corner of Stadium Way and Scott Avenue. The plan, backed by then-Mayor Sam Yorty, would have cost $10 million dollars and taken away 63 acres of the park-- in addition to contributing to the noise and congestion already supplied by nearby Dodger Stadium. The CCSEP rallied public support by mailing letters to City Hall, publicizing the plight of the park in the media, and receivng a visit from Supreme Court Justice William Douglas who urged his support for retaining the site for recreation. In August of 1966, the CCSEP claimed victory, and the City selected 31 acres at Pico and Figueroa as the convention center's new home. Contained in this series are sixteen folders of letters, legal documents, petitions, press clippings, and other papers related to the proposed building of the convention center in Elysian Park. There is some overlap of issues and types of materials with the preceding series which also deals with the oil lease battle.
