Green Infrastructure - Collaborating & Coordinating with Communities

October 29 | Symposium Panel 3 

Green Infrastructure - Integration & Innovation

Green infrastructure has the ability to soak up rain and heat (with vegetation) but how do we know if it's soaking up success?

Beginning with the Water Augmentation Study and later Elmer Avenue, Council for Watershed Health (CWH) has built a reputation for leveraging green infrastructure (GI) to slow, spread and sink (or soak up) stormwater where it falls, producing as many benefits as possible, and creating a sustainable landscape ethic in Southern California. CWH has since gathered lessons learned, best practices, and strategies to help inform future project design, implementation, and monitoring strategies. 


Today, significant investments in GI, Nature-Based Solutions and Low Impact Development Best Management Practices (LID BMPs) are being made throughout California and in LA County with its Safe, Clean Water Program (Measure W) and Clean Neighborhood Parks and Beaches Program (Measure A). CWH and its partners recognize the need for common strategies and coordinated efforts to measure the success of GI projects from science-based, ecological, equity-driven and watershed perspectives.


We invite you to join us along with agencies, municipalities, academia, and GI practitioners, as we host our Rain or Shine: Soaking up Success Symposium and provide a forum to: 

>> Examine GI from multiple perspectives

>> Learn how GI benefits are being quantified

>> Share lessons learned to inform future design, implementation, and monitoring





When implementing green infrastructure, we aim to reduce flooding, improve water quality, increase water supply, and enhance biodiversity, climate resiliency, public health and well-being. This panel will focus on these benefits and discuss how to plan, implement, and monitor projects and share findings.

Green Infrastructure - Indices, Metrics, & Monitoring

September 23, 9am-12pm


Green Infrastructure - Coordination & Collaboration with Communities

October 15, 9am-12pm

 Community collaboration and participatory decision-making are essential for successful green infrastructure project planning and equitable placemaking. Panelists will focus on strategies for including community members in green infrastructure project planning to implement and sustain public health and community benefits.


Green Infrastructure - Integration & Innovation

October 29, 3pm-5:30pm

State, regional, and private investments are
setting the scene for green infrastructure
solutions in Los Angeles. This panel brings
together water agencies in our region to discuss challenges and opportunities for integrated and innovative projects that leverage resources to ensure the equitable distribution of ecological, social, and economic benefits.
