Stormwater Infrastructure - Safer Today, Stronger Tomorrow
Why Is Stormwater Infrastructure So Important?
Protecting Residents and Businesses from Flooding
Safe communities need robust stormwater systems to protect residents and businesses from flooding.
- When stormwater is managed effectively, it is channeled away from homes and businesses and safely into waterways or storage facilities
- When streets and other low-lying areas become flooded, the water can quickly rise to dangerous levels
- Flooding can be costly
- Flooding can also disrupt critical infrastructure such as power, water, and transportation systems, which can create further safety risks for residents.
Our stormwater system is comprised of:
- 130 miles of storm drains
- 20 miles of open creeks and drainage channels
- One flood control lagoon
- Ten pump stations
- Three-mile Bayfront levee
- Future storms will be more intense, putting more pressure on the City’s stormwater infrastructure. Through careful planning, we can build resilience in the face of climate change and aging infrastructure. Safer today, stronger tomorrow.

Dedicated Resources to Protect Our Community
A dedicated revenue source would fund repairs and improve aging infrastructure, so residents and businesses can be better protected from flooding.
- During heavy rain events, stormwater can overwhelm the existing
system and cause flooding. Stormwater management systems, including levees and pumps, can help prevent flooding and protect communities from damage caused by severe storms.
- System failures happen more frequently with aging infrastructure, leading to worsened flooding conditions over time.
- Recent large storm events have highlighted the City's aging infrastructure deficiencies.
Projects will include:
- Storm drain Condition and Capacity Assessments
- Updated Stormwater Master Plan
- San Mateo Creek and Marina Lagoon Dredging and Maintenance Permitting
- Flood prevention and storm water system capacity improvement projects:
- Drainage Area Projects
- Stormwater pump station upgrades
- Levee improvements
- Green Infrastructure Projects
- Regulatory Compliance
- $8.4 million per year is needed to strengthen and rehabilitate our stormwater infrastructure
- The average cost per home is around $10-$19 per month
- Funds would be fully dedicated to stormwater infrastructure only
- Proposed fee would be finalized upon completion of the Fee Report in July 2023
Keeping Our Water Clean Keeps Us Safe
Properly managed stormwater systems protect the health and wellbeing of local residents, wildlife and habitats by reducing pollution in our local waterways and the San Francisco Bay.
Properly managed stormwater systems can filter out pollutants and trash from stormwater runoff before it enters local waterways and the San Francisco Bay, protecting aquatic life and habitats.
We are required by law to prevent contamination of stormwater by utilizing clean work practices, inspecting businesses and construction activities, and educating the public. We are a member of a comprehensive countywide effort to prevent stormwater pollution. For more information, visit San Mateo Countywide Water Pollution Prevention Program.
Resource to Build Resiliency
Stormwater can become a resource for community development, rather than a nuisance, when stormwater management systems have the funding and support needed for innovative and sustainable solutions.
Marina Lagoon
The Marina Lagoon (Lagoon) is part of the City’s stormwater system. This aquatic gem provides flood control and recreation to the entire community, as well as wildlife and ecological benefits. Significant improvements and lagoon dredging are needed to protect these benefits.
Sustainable stormwater management promotes healthier and more resilient ecosystems, and can create new opportunities for recreation and habitat restoration.
Green Infrastructure
Green Infrastructure allows rainwater to soak and filter into the ground, reducing the quantity of water and pollutants flowing into local creeks.
