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.

NOAA is an agency that enriches life through science. Our reach goes from the surface of the sun to the depths of the ocean floor as we work to keep citizens informed of the changing environment around them. From daily weather forecasts, severe storm warnings and climate monitoring to fisheries management, coastal restoration and supporting marine commerce, NOAA’s products and services support economic vitality and affect more than one-third of America’s gross domestic product.

This organization was established in 2014 when NOAA combined two offices: the Coastal Services Center and the Office of Ocean and Coastal Resource Management. The basic missions of the two programs remain intact, but the new organizational structure is bringing value-added services to taxpayers.

The National Sea Grant College Program, administered by the National Oceanic and Atmospheric Administration (NOAA), is a federal/state partnership that matches NOAA Sea Grant expertise and resources with state academic institutions. The Mississippi-Alabama Sea Grant Consortium (MASGC), created in 1972, is one of 32 Sea Grant programs.

Scripps Institution of Oceanography is one of the oldest, largest, and most important centers for ocean and earth science research, education, and public service in the world. Research foci at Scripps includes physical, chemical, biological, geological, and geophysical studies of the oceans and earths.

California Sea Grant (CASG) is one of 33 state programs funded by the National Sea Grant College Program, part of the National Oceanic and Atmospheric Administration (NOAA). Matching funds come from the states and private sources. California Sea Grant is administered by Scripps Institution of Oceanography at the University of California, San Diego.

Our mission

The National Ocean Service provides data, tools, and services that support coastal economies and their contribution to the national economy. NOS is dedicated to advancing the following priorities:

Established in 1968, Washington Sea Grant (WSG) began as a federal experiment in local investment, building on the University of Washington’s academic strengths in marine science, engineering and policy. In 1971, it became one of the first four programs designated nationally as a Sea Grant College. Today, WSG is part of a national network of 30 Sea Grant colleges administered by the National Oceanic and Atmospheric Administration, U.S. Department of Commerce.

EcoAdapt is at the center of climate change adaptation innovation. We provide support, training, and assistance to make conservation and management less vulnerable and more Climate Savvy. Over the past 200 years, great strides have been made in the world of conservation and now all of that is at risk because of climate change. EcoAdapt is working to ensure the success of these past efforts by delivering a framework for climate adaptation.

UGA Marine Extension and Georgia Sea Grant provides research, education, training and science-based outreach to assist Georgia in solving problems and realizing opportunities for its coastal and marine environments. By advancing research, education and training, and outreach, UGA Marine Extension and Georgia Sea Grant promotes the economic, cultural and environmental health of Georgia’s coast and prepares citizens to become good stewards of coastal ecosystems and watershed resources.

UC San Diego is transforming California and a diverse global society by educating, by generating and disseminating knowledge and creative works, and by engaging in public service.
