He organized the Planning Directors Committee in the 1940s, which proposed metropolitan planning principles and drafted an advisory regional planning board statute in the 1950s. Kent co-founded the People for Open Space in 1958 and helped the Association of Bay Area Governments to prepare the nation's first metropolitan greenbelt plan in the late 1960s. He retired from Universty of California in 1974 and thereafter devoted his life into greenbelt movements. This paper traces his efforts in regional planning in the Bay Area and dislosed his contributions to metropolitan planning in the United States.
