PHOENIX (AP) -- Phoenix leaders are beginning a national search to find a replacement for outgoing City Manager David Cavazos. Cavazos announced on Aug. 1 that he's stepping down to become the new city manager in Santa Ana, Calif. He had been Phoenix's city manager since 2009. Phoenix City Council members voted 8-1 Wednesday to hire an executive-recruitment firm to oversee the search process for Cavazos' successor. It could take up to six months before Phoenix hires a new city manager, but Mayor Greg Stanton says he's not set on an "artificial timetable." Stanton says Phoenix should instead focus on having the right process in place so it can hire the best city manager.
