Planning Commission — June 11, 2026
The December 2025 storm wrecked several roads and clogged drainage pipes with sediment. The CIP adds retention basins and drainage projects — like the C01 basin and Walnut Street Basin — to prevent a repeat.
Planning Commission — March 26, 2026
Commissioners say residents are frustrated after the major storm flooding — eroded roads, caved-in fences, and yards washed out. They want the city to do more small-scale outreach, like delivering fill dirt and responding to resident reports, to lower the temperature.
City Council — March 3, 2026
The Christmas Eve storm dropped up to 6 inches of rain in 12 hours in some watersheds — a 500-to-1,000-year event — washing out roads, filling basins with sediment, and damaging drainage infrastructure. Cleanup is ongoing, and the city is pursuing a $4.5 million Temecula Avenue basin project plus county projects like the $80 million Bandicoot/Cedar basin.
