Diamond Bar City Council Meeting April 7, 2026

The City of Diamond Bar held its City Council meeting on April 7, 2026. The meeting included presentations such as the Miss Diamond Bar court recognition and certificates for the 2025-2026 VEX V5 robotics team. A significant procurement-related discussion focused on the LA County Sanitation District's proposed sewer rate increase under Proposition 218. The district presented details on the rate adjustment, citing inflation and capital projects for aging infrastructure as primary reasons. The proposed increase would add approximately $2.75 per month to a typical single-family home's sewer bill over a five-year period. The council discussed the rate-setting process, funding for clean water and infrastructure projects, and the potential for future rate increases. The council approved the consent calendar, which included resolutions related to sewer, grading, paving, and storm drain bonds for the Brea Canyon Business Park. No new contracts or vendor selections were reported during the meeting.
