2025 Conference Theme

Resilient Watersheds, Innovative Solutions

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.

    Capstone Session

    CASQA is excited to announce that our Capstone Event at this year’s annual conference will feature a Gubernatorial Candidate Forum.

    Attendees will have the opportunity to hear directly from the candidates for Governor about their perspectives on issues impacting stormwater management and water policy in California.

    To date, we have a confirmation from Mayor Antonio Villaraigosa. We are finalizing responses from the other candidates and will share more as we get closer to the event date.
