This document is the fourth and final report produced as part of this collaborative effort. Previous reports developed during this project describe the evolution of USACE evaluation approaches from prior eras of planning to the present day (Ehrenwerth et al., 2022), investigate where and how NBS were considered in planning studies from 2005–2020 (Windhoffer et al., 2023), and review relevant planning and valuation methods that could be applied by USACE to improve NBS evaluation and were considered to inform the subsequent case study analysis (Fischbach et al., 2023).
