DUBLIN -- Former Mayor Janet Lockhart, a leader in many community groups, has been named the 2012 Dublin Citizen of the Year, and Camille Chabot, a Dublin High School senior active in a cheer team and Irish dance troupe, has been named the Young Citizen of the Year.

The Tri-Valley Youth Court, which brings juvenile offenders before a jury of their peers, was named the 2012 Dublin Organization of the Year. City officials announced the three awards last week at a banquet in the Shannon Community Center for the annual honors recognizing volunteers who made a difference in the quality of life in Dublin.

Lockhart, a councilwoman between 1996 and 2007, was honored for her continuing leadership and work for several civic and educational groups. She is the executive director of Dublin Partners in Education, which raises funds for Dublin public schools.

In 2012, she was president of the Alameda County Fair Board, and the boards for the Dublin Sister City Association, Las Positas College Education Foundation, the Valley Children's Museum, and the Dublin Unified School District Pride/Integrity in Action Program. She volunteers for many more causes, including reading children's stories she wrote to students in several Dublin schools.

"Busy as Janet always is, she can always find time to help her fellow citizens. No task is too grand or too small," said Ted Kaye, one of four local residents who nominated Lockhart. "She is the city of Dublin's most endearing and authoritative ambassador."

Chabot, the Dublin High student, volunteers for many causes, which include working in a second-grade classroom at Green Elementary School. A dancer with the McGrath Irish Dance Troupe in Dublin, Chabot has demonstrated Irish dance at many public events.

Chabot was among 31 Dublin representatives who performed a drama skit that helped Dublin win an All-America city award from the National League of Cities in 2011. She is captain of the Dublin High School varsity cheer squad, which took first place in its division in 2012 and 2013 at the JAMZ National competition.

Tri-Valley Youth Court opened up in 2008, providing youth criminal offenders an alternative to regular juvenile penalties. Teen offenders face a jury of their peers, who come up with sanctions such as community service, jury duty, life choice classes or apologies and restitution.

The youth court operates year-round with some eight adult volunteers acting as judge, mentor and case manager and 20 to 25 teens acting as clerks, advocates and jurors. The court will receive $500 for the award. Awards of $300 will be given to Lockhart's and Chabot's favorite nonprofit group.
