Parcel-scale Sea Level Rise Vulnerability for Puget Sound: Phase 2
HSIL23-24113
This project implements a second phase of the project Prioritizing Sea Level Rise Exposure and Habitat Sensitivity Across Puget Sound (Near Term Action 2018-0685) funded between 2019-2022 by the Habitat Strategic Initiative Lead. In phase 1, a quantitative sea level rise vulnerability framework, designed to identify vulnerabilities to coastal flooding and erosion exacerbated by sea level rise, was developed and applied to ~111,000 parcels in Puget Sound. The results were then shared and discussed with a variety of interested groups between January and June of 2022, and a set of next steps and improvements identified. This project addresses those recommendations by (1) integrating new data to improve the framework and expand the spatial footprint of the analysis west to the mouth of the Strait of Juan de Fuca, (2) re-calculating exposure, sensitivity and vulnerability scores for the entire study area, and (3) publishing the results in an online interactive format as well as implementing other communications actions to facilitate the use of the analysis in restoration, land use, and hazard mitigation planning.
