City of Diamond Bar
Diamond Bar City Council, District 3
This person holds your district's seat on Diamond Bar's 5-member City Council. They vote on city ordinances, the budget, and land use.
Only one candidate qualified for this seat. Incumbent Andrew Chou has been on the council since 2018. He was the city's mayor in 2023. He appears unopposed for a third term. This contest is settled and your vote here does not change the outcome.
This person holds one of five district seats on Diamond Bar's City Council. They vote on city ordinances, the budget, and land-use decisions. The term is four years. Council members choose one of their own to serve as mayor and mayor pro tem, presiding over meetings but casting only one vote like any other member.
With no opponent, the useful question is what he has done with the seat, not who to choose. Chou has held the office since November 2018, after prior service as a Diamond Bar Parks and Recreation Commissioner, and now sits on a string of regional boards that reach beyond the city itself.
