Coastal Risk Reduction and Resilience: Using the Full Array of Measures

This US Army Corps of Engineers report details different measures for reducing coastal flooding and erosion risks, including natural or nature-based features (such as wetlands, dunes, and living shorelines), nonstructural interventions (such as land-use policies, building codes, and early warning systems), and structural measures (such as seawalls, levees, and breakwaters).    

This report provides a planning approach to help decisionmakers assess the full array of measures and the suitability of different approaches for reducing coastal risk based upon site-specific conditions.  It also helps decisionmakers assess the full range of economic, environmental, and social benefits that can be delivered by different approaches.

Tables of the different features are presented in Appendix A to the report with summaries of how each feature can enhance coastal resilience, performance factors, and potential socioeconomic and environmental outcomes and benefits. The features explored include: seagrass beds, coral reefs, oyster reefs, salt marshes, barrier islands, beaches, dunes, freshwater wetlands, maritime forests, nonstructural options, levees, storm surge barriers, seawalls and revetments, groins, and breakwaters.

A more detailed framework for assessing natural and nature-based coastal resilience measures was published by the Army Corps in 2015, which provides additional information about NNBF approaches.
