The Sustainable Lands Strategy (SLS) has identified four major river reaches in Snohomish County on which to focus its multi-benefit planning approach. The consensus among those involved is that a one-size-fits-all approach will not work in every part of Snohomish County. Therefore, each reach has its own plan to address its unique needs and priorities.

By focusing on the reach as a whole and stressing mutual benefits, the SLS can achieve long-term agreement on the fish and farm net gains needed by the participants in a larger, regional picture.

This Vulnerability Assessment documents the flood hazard and related climate change vulnerabilities for the Snohomish and Stillaguamish rivers. The results of the assessment will inform outreach to vulnerable populations as well as future flood risk reduction planning efforts.
