Washington Coastal Resilience Project

The Washington Coastal Resilience Project (WCRP) is a three-year effort to rapidly increase the state’s capacity to prepare for coastal hazards, such as flooding and erosion, that are related to sea level rise. The overall aim of this collaborative project is to improve risk projections, provide better guidance for land use planners and strengthen capital investment programs for coastal restoration and infrastructure. These are the tools coastal communities need to become more resilience to coastal hazards.

The Climate Impacts Group is working with a diversity of partners from across Washington state to produce a range of science, guidance, trainings and communications products as part of the WCRP project.

Sea Level Rise Projections

Projected Sea Level Rise for Washington State – A 2018 Assessment

This report provides community-scale sea level rise projections out to the year 2150 for 171 different locations around coastal Washington. For each location, this report assesses the likelihood that sea level rise will reach or exceed a certain level relative to the present. This probabilistic approach is designed to support direct application in risk management and planning.

The project is primarily funded by a grant from the NOAA Regional Coastal Resilience Grants Program (grant #NA16NOS4730015). Additional funds were provided by the State of Washington as well as the Pacific Northwest Climate Impacts Research Consortium (CIRC), which is partially funded by the Regional Integrated Sciences and Assessments program under NOAA grant #NA15OAR4310145.

Sea Level Rise Visualizations

Data Visualizations of the WA Sea Level Rise Projections

We worked with Tableau and Seattle Public Utilities, with support from EarthLab, to create interactive data visualizations of the 2018 Washington State Sea Level Rise projections.

Mapping Sea Level Rise

Guidelines for Mapping Sea Level Rise Inundation for Washington State

This report provides guidelines for mapping sea level rise inundation throughout Washington State. These guidelines are primarily directed towards staff members with a GIS background who may be asked to prepare maps showing the extent of relative sea level rise inundation.

This work leverages results from the Washington Coastal Resilience Project, which is funded by a grant from the NOAA Regional Coastal Resilience Grants Program (grant #NA16NOS4730015). Funding for this report was provided by the United States Environmental Protection Agency Natural Estuary Program (NEP) under assistance agreement PC-01J22301 through the Washington Department of Fish and Wildlife.

Sea Level Rise & Restoration

Sea Level Rise Considerations for Nearshore Restoration Projects in Puget Sound

This considerations document aims to assist restoration professions with considering sea level rise impacts in the planning and design of nearshore restoration projects in Puget Sound. Specifically, this document identifies questions that sea level rise raises for process-based restoration projects and identifies information needs that can assist with evaluating these questions. 

This work was jointly funded by NOAA Regional Coastal Resilience Grants Program (grant #NA16NOS4730015) and the United States Environmental Protection Agency under assistance agreement PC-01J22301 through the Washington Department of Fish and Wildlife.

Extreme Coastal Water Levels

Guidelines to Support Sea Level Rise Planning in Washington State

This report provides guidelines for assessing exposure to current or future coastal flooding during extreme coastal water level events—whether these are due to tides, surge, wave run-up, or, more likely, a combination of the three. These guidelines provide information about the current and future magnitude of extreme coastal water levels across Washington State and the underlying processes that influence them. This information is intended to be combined with sea level projections to assess future exposure to flooding along Washington’s coastline. Although the results of the analyses in this report can be combined with any available sea level projections, this report is intended as a companion to the localized sea level rise projections (Miller et al., 2018) developed as part of the Washington Coastal Resilience Project.

How to Choose

A report and webinar on selecting sea level rise projections for Washington State

This 25-page report and the accompanying webinar helps coastal planners, engineers, climate adaptation specialists and other decision makers understand the various sea level rise data subsets and how to use them to make sound decisions for their particular project and community. The guide will help users make three critical choices when using sea level rise data: selecting an appropriate time frame, weighing the probabilities of different sea level rise projections against the risk, and choosing whether to consider projections that assume a high or low level of future greenhouse gas emissions.
