Application Guide for the 2022 Sea Level Rise Technical Report
Available in English and Spanish (attached below).
The recently released federal Global and Regional Sea Level Rise Scenarios for the United States: Updated Mean Projections and Extreme Water Level Probabilities Along U.S. Coastlines (2022 Sea Level Rise Technical Report) is a synthesis of the latest available science on sea level rise. It was developed by an interagency team of experts as an update to the Sweet et al. (2017) report (2017 Sea Level Rise Technical Report) and serves as a technical input to the Fifth National Climate Assessment. This document, Application Guide for the 2022 Sea Level Rise Technical Report (Application Guide), is designed to assist decision-makers and coastal professionals with applying and integrating the information in the 2022 Sea Level Rise Technical Report into local sea level rise planning and adaptation decisions.
This Application Guide is national in scope, and it includes examples from different geographic regions. It describes how updated sea level rise scenarios and related science information in the 2022 Sea Level Rise Technical Report can be considered and applied through various coastal hazard evaluation and planning approaches.
The Application Guide is divided into the following sections:
- Section 1: Purpose.
- Section 2: Introduction to the updated science from the 2022 Sea Level Rise Technical Report.
- Section 3: Overall considerations when applying sea level rise scenarios in planning efforts.
- Section 4: Examples of specific application approaches that can be used to address the uncertainty in the amount and timing of future sea level rise when making decisions.
- Section 5: Additional resources for thinking about the next steps.
This Application Guide is not a comprehensive guide on how to plan for sea level rise. Adapting to rising seas requires robust and continual efforts that consider a complex array of place-based sociocultural, economic, policy, physical, and ecological factors. This document provides broad guidance on where to start with sea level rise planning and on how to consider the updated information provided in the 2022 Sea Level Rise Technical Report. It includes recommended practices for decision-making in the face of uncertainty but does not offer formal regulatory or engineering guidance.
