UNION CITY -- Carol Dutra-Vernaci was sworn in at a City Council meeting Tuesday night -- exactly five weeks after she was elected Union City's first female mayor.

She replaced Mark Green, who had served as Union City's mayor since 1993. Dutra-Vernaci, 58, addressed the standing-room-only crowd that packed the council chambers, praising Green for his 19 years of service.

Dutra-Vernaci was elected after running unopposed. She previously served three terms on the City Council from 1997-2010, and has headed the city's Economic Development Advisory Team and the Community Emergency Response Team.

Union City Councilman Jim Navarro, who captured his third term and nearly 67 percent of the vote while defeating challenger Jose Estrella last month, also was sworn in at the meeting.
