Diamond Bar City Council Meeting July 21, 2026

The City of Diamond Bar held a City Council meeting on July 21, 2026, which included a detailed presentation by the Walnut Valley Water District on their 40-year recycled water system, highlighting its expansion, benefits, and future plans. The council also discussed a significant procurement-related item: a proposed local transactions and use tax (TUT) ballot measure intended to address a forecasted structural budget deficit. The measure, if approved by voters, would add a 1% local sales tax generating approximately $6 million annually to support essential city services such as public safety, infrastructure maintenance, and parks. The council reviewed past tax initiatives, current budget challenges including rising costs for public safety contracts and infrastructure, and extensive community outreach efforts. After public comments and council deliberations, the council voted 4-1 to place the TUT measure on the ballot for voter consideration. Other agenda items included approval of consent calendar items such as a copier maintenance contract with Integris LLC for up to $85,000 through 2029 and ratification of a check register totaling nearly $5.9 million. The meeting concluded with council subcommittee reports and welcoming a new sheriff's department lieutenant.
