Remote, Coastal, and Small Watersheds Act of 2020 This bill authorizes the U.S. Army Corps of Engineers in conducting a study of hurricane and storm damage reduction to recommend certain projects in remote, coastal, and small watersheds without the need to demonstrate that the projects are justified solely by national economic development benefits. In considering whether to recommend a project, the Corps must consider the benefits of the project to (1) public health and safety of the local community and communities that are located in the region to be served by the project and that will rely on the project, (2) hurricane and storm damage effects on local and regional economic opportunities, (3) welfare of the regional population to be served by the project, or (4) social and cultural value to the local community and communities that are located in the region to be served by the project and that will rely on the project.
