Flooding & Stormwater Infrastructure — A $9 Million Annual Need
active• sanmateo
Flooding is one of San Mateo's most persistent and costly quality-of-life challenges, and its aging stormwater system is increasingly unable to handle intensifying storms. The city estimates it needs approximately $9 million per year to strengthen and rehabilitate its stormwater infrastructure, but currently lacks a dedicated funding source — and the proposed Community Flood & Storm Protection Initiative would add a stormwater fee averaging around $8 per month per single-family home, raising roughly $4 million per year toward the system. A major milestone was recently reached: in September 2025 the city celebrated completion of a $597 million wastewater treatment plant upgrade — the largest infrastructure project in city history — but the stormwater challenge is separate and still unresolved. The city has now published a Draft Storm Drain Master Plan for public review, asking residents to share real-world flooding experiences to help calibrate the plan's future flood predictions.
