Sea Level Rise Adaptation Framework
Point Blue Conservation Science and the San Francisco Estuary Institute, in partnership with the County of Marin, developed the Sea Level Rise Adaptation Framework. It is a user guide to help planners and others to include nature-based strategies to address sea level rise hazards. The framework helps planners determine which nature-based measures are suitable given specific site conditions, and offers an approach for evaluating which combination of measures are the most appropriate to achieve desired outcomes. Nature-based solutions to sea-level rise include measures like restoring coarse beaches where appropriate to reduce wave energy, conserving and restoring wetlands that can act as buffers, and preparing “migration spaces” that marshes can transition into as sea levels rise.
The resources in the user guide are intended to help coastal decision-makers:
- efficiently identify a range of natural and nature-based, landscape-scale adaptation strategies that can address coastal climate change vulnerabilities
- evaluate how well these adaptation strategies achieve coastal community and stakeholder objectives, and prioritize their implementation.
We demonstrate the application of the framework by illustrating the decision-making process with examples from two regions of the Marin County shoreline
The framework, case studies, and resources presented in our user guide are a step toward addressing the challenges in transitioning from community vulnerability assessment to action. The adaptation phase of Marin County’s Bay Waterfront Adaptation and Vulnerability Evaluation (BayWAVE) project was used as a test case with the intent that the framework developed be applicable around the entire San Francisco Estuary and beyond.
