About

The Transforming Shorelines Collaborative (TSC) brings together practitioners, decision-makers, and community members working at the intersection of nature-based shoreline adaptation and urban water management to advance shoreline resilience projects that provide multiple benefits for people and ecosystems.

The TSC meets 3-4 times per year for interactive in-person meetings as well as hybrid meetings and informational webinars. Everyone is welcome to join!
