 Cassidy faced the downtown voters in April 1963 and was elected to a four-year term.In the meantime, though, a move was afoot to shift the 12th District City Council seat into the San Fernando Valley, which had experienced steady population growth over the years, and in July 1964 the councilman agreed to the arrangement and said he would relocate into his new district area.The new Valley district included Granada Hills, Northridge, Chatsworth, Panorama City and the northern half of Canoga Park.
