San Diego Enhances Flood Protection with Stormwater Channel Improvements
San Diego’s Stormwater Department has finalized a crucial infrastructure project in Valencia Park, significantly improving flood resilience for nearby communities. The project focused on clearing the channel and stabilizing slopes within the Chollas Creek Watershed, a vital component of the city’s stormwater management system.
Valencia Park Stormwater Project Details
Over several months, city engineers and crews worked to remove obstructions and reinforce the stormwater channel. This proactive measure aims to mitigate flood risks during periods of heavy rainfall.
Did You Know? The Chollas Creek Watershed covers approximately 32 square miles and is one of the most urbanized watersheds in San Diego County [1].
The project involved a substantial cleanup effort, with City workers and Urban Corps partners removing roughly 1,700 tons of debris and invasive vegetation. Additionally, crews repaired 150 feet of eroding channel slope near imperial Avenue and Stevens Way.
Key Project Achievements
- Removed approximately 1,700 tons of debris and invasive vegetation.
- Repaired 150 feet of eroding channel slope.
- Improved stormwater flow capacity.
City’s Commitment to Flood Resilience
Todd Snyder, Stormwater Director, emphasized the importance of the project, stating, “This channel-clearing project is a vital investment as we continue modernizing our stormwater system to help reduce flood risk citywide. These proactive steps to repair and clear channels ahead of the rainy season are critical as we work to protect our neighborhoods against flooding.”
These projects are part of San Diego’s ongoing commitment to strengthening flood resilience across all neighborhoods and maintaining a safe and efficient stormwater system.

Future Investments in Stormwater Management
The proposed budget for Fiscal Year 2026 includes provisions for maintaining the 18 miles of storm channels addressed after the January 2024 floods,including 12 miles within the Chollas Creek Watershed.
| Area | Miles of channels | Status |
|---|---|---|
| Total Channels Addressed (Post-Jan 2024 Floods) | 18 | Under Maintenance |
| Chollas Creek Watershed | 12 | Under Maintenance |
Community Education and Preparedness
In December 2024, the City launched an educational campaign, mailing informational brochures in English and Spanish to approximately 10,000 residents and property owners in floodplain areas. These brochures provided essential guidelines on emergency preparedness, evacuation plans, flood insurance, and other critical flood-related resources.

The Importance of stormwater Management
Effective stormwater management is crucial for urban environments to prevent flooding, protect water quality, and maintain public safety. As cities grow, impervious surfaces increase, leading to higher volumes of runoff during rain events. Properly designed and maintained stormwater systems can mitigate these impacts, safeguarding communities and ecosystems.
