The wide range of prospective benefits that can be achieved by incorporating elements of EWN cannot currently be accounted for in USACE planning practices. In particular, underutilization of Natural and Nature-Based Features (NNBF) is a missed opportunity for the agency to mainstream resilience thinking throughout its practices. Improving the business case for NNBF and other innovative strategies can provide the basis for the evolution of USACE practice to support selection of alternatives that reflect current agency stated values and priorities.
