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.
Tye is campaigning on continuity: two decades on the council, a record fifth term as mayor, and a resume built on prior service on the Planning Commission and Parks and Recreation Commission. Torres is campaigning on six stated priorities — economic development, public safety, infrastructure, open space, homelessness, and civic engagement — framing himself as a first-time candidate who does his homework rather than a career politician.
