Integrating Climate Resilience in Puget Sound Floodplain and Working Lands Programs

Full Title

Integrating Climate Resilience in Puget Sound Floodplain and Working Lands Programs

Project Overview

In response to the Floodplains by Design (FbD) and Puget Sound Natural Resource Alliance (PSNRA) funding opportunities, many communities have proposed projects that address floodplain restoration goals. To date, few such proposals have addressed climate impacts in risk assessments or project design. Yet climate – both year-to-year variability and anticipated 21st century climate change – has major impacts on floodplains, primarily via changes in flooding and summer water supply. Furthermore, the risks posed by climate are not uniformly distributed across the landscape: some areas are much more vulnerable to changes than others. Ultimately, information on climate vulnerability is needed to compare risks among watersheds and to prioritize projects within a specific watershed. This project will distill information gathered from in-person interviews, aimed at developing an initial understanding the climate information needed for robust floodplain planning. This report will also include a summary of relevant impacts science, maps of existing projections, and a prominent description of key science gaps. Written to serve as a resource for both regional and project-scale planning, the intent of the report is to summarize information that is needed to support multi-objective floodplain planning.
