Add your voice to the call for a strong and effective, regionally coordinated response to sea level rise.

Please sign our petition today! 
This is our last chance to solidify a strong, regional approach to sea level rise for the San Francisco Bay, and ensure a thriving and resilient future for decades to come! The latest draft Regional Shoreline Adaptation Plan (RSAP) reflects our strong advocacy efforts and demonstrates the Bay Conservation and Development Commission’s (BCDC)’s commitment to regional coordination. But now they are being asked to weaken the RSAP’s requirements, which would severely undermine regional coordination and accountability. Please tell BCDC that to safeguard a sustainable future for Bay ecosystems and communities, alike, the RSAP must be strengthened, not watered down. The Bay Area needs a strong RSAP that prioritizes equity, natural and nature-based solutions (NNBS), and safety from contamination threats. 

Read our joint statement, with dozens of like-minded organizations, to BCDC.
