In early June, "Berkeley" departed San Diego and headed north to Oregon for the Portland Rose Festival, remaining there until 12 June. The warship returned to San Diego three days later and, over the next six weeks, conducted two midshipmen training cruises and another law enforcement patrol. In August and September, the guided-missile destroyer concentrated on refresher training and, in early October, she participated in underway training while in transit to San Francisco for "Fleet Week '91." Returning to San Diego on 25 October, the warship carried out a succession of engineering drills in the southern California operating area through November. Heading back to Portland on 2 December, "Berkeley" took part in the city's 50th anniversary commemoration of the bombing of Pearl Harbor.
