CASQA 2025 Annual Conference - Sep 15-17   Arrow right

CASQA provides a collaborative space where the preeminent thought leaders in California come together to share knowledge, build community, and advance the future of stormwater management. Our 2025 conference theme, Resilient Watersheds, Innovative Solutions, emphasizes the importance of resilience – not just in the natural environment, but in the people and communities that steward our watersheds. Resilient watersheds are shaped by our ability to adapt, learn from each other, and implement innovative solutions that advance sustainable stormwater management and foster long-term stewardship.

We invite you to join us in Pasadena, where we will learn from each other, share solutions, and work together to shape a more resilient future for our watersheds and communities.
