This report presents the results of EcoAdapt’s efforts to survey adaptation action in marine fisheries management by examining the major climate impacts on marine and coastal fisheries in the United States, assessing related challenges to fisheries management, and presenting examples of actions taken to decrease vulnerability and/or increase resilience. First, we provide a summary of climate change impacts and secondary effects on fisheries, focusing on changes in air and water temperatures, precipitation patterns, storms, ocean circulation, sea level rise, and water chemistry.
Coastal communities face constant challenges from shoreline erosion. Although erosion is a natural coastal process, many valuable resources border the nation’s coastline. Shorelines need protection from damage caused by intense storms, wave erosion, and sea level rise. Shoreline stabilization does not need to create a barrier between land and water, as happens with hard shoreline stabilization structures like seawalls and bulkheads. New stabilization options, like living shorelines, are gaining attention as an alternative to traditional shoreline stabilization techniques.
Public Private Partnerships (P3s) have the potential to help many communities optimize their limited resources through agreements with private parties to help build and maintain their public infrastructure. P3s have successfully designed, built, and maintained many types of public infrastructure, such as roads, and drinking water/wastewater utilities across the U.S. Until recently, there have been no P3s specifically developed for stormwater management or Clean Water Act requirements.

Tidal Flooding is an educational, online, narrated presentation provided by the NOAA Office for Coastal Management that describes tidal flooding and the risks communities may face with increased tidal flooding from heavy rains, sea level rise, and continued coastal development. The presentation outlines the formation of extreme high tides, potential impacts of extreme high tides, and how flooding will change with sea level rise.
The Coastal Flood Exposure Mapper helps communities understand their risks and vulnerability to coastal flooding. The mapper was first developed following Hurricane Sandy to provide a tool to show areas susceptible to coastal flooding, storm surge, and inundation, and to inform communities and local authorities about the risks their communities face. Users are able to explore maps that show how natural resources, communities, and infrastructure and development will be exposed to coastal flooding hazards.
Coastal County Snapshots is an online tool that produces user-friendly reports identifying and describing three categories of coastal hazards and change — flooding risk, wetland impacts, and ocean jobs impact — for selected coastal counties in the United States. Users select a coastal county, and the tool generates reports for the three categories identifying and describing changes that have occurred (e.g., changes in land cover, job trends) and important sectoral information (e.g., amount of coastal infrastructure at risk from flooding, how wetlands can be used to reduce flood impacts).

The USGS Coastal Change Hazards Portal allows users to explore and interact with data, models, and tools related to three primary coastal hazard categories: severe storms, shoreline change, and sea level rise. The portal hosts an on online visualization tool for all three hazard categories, and users can download all source data, publications, and relevant resources for external use. In addition, users can group data and resources from different hazard areas to explore synergistic interactions of different coastal hazards.
