BayWAVE coordinates with all of East Marin's cities and towns to provide an ongoing public process that helps local communities understand and prepare for sea level rise.

BayWAVE's multi-jurisdictional coordination is critical, as sea level rise crosses political boundaries to impact our shared resources, utilities, and infrastructure.

In 2017, BayWAVE completed the Marin Shoreline Sea Level Rise Vulnerability Assessment, a technical report detailing how shoreline flooding will worsen with sea level rise if no actions are taken.
