Where do they come from? What are some examples of strategies for ecosystem restoration projects?
Puget Sound Nearshore Ecosystem Restoration Project (PSNERP) Nooksack River Delta Setback Levees - Policy Concurrence (2016)
This memorandum from the Assistant Secretary of the Army (Civil Works) (ASA(CW)) articulates Army policy: "It is the policy of the Army to encourage floodplain restoration, as it encourages community resilience and provides benefits to both the ecosystem and human wellbeing. The use of levee set-backs, along with other measures to increase and enhance floodplains, is encouraged in aquatic ecosystem restoration projects. It is also the policy of the Army not to increase flood risks or decrease life safety without sufficient justification. When formulating restoration projects that propose restoring floodplains, the Corps should use the existing level of flood risk as the formulation baseline. If any changes to the baseline are recommended, then the Corps should demonstrate the rationale for the increase or decrease in the level of flood risk management. If the level of flood risk associated with an ecosystem restoration project is decreased, then the risk reduction increment above the baseline must be cost effective and incrementally justified. If the level of flood risk is increased as a result of ecosystem restoration, then the Corps must mitigate any induced damages as part of the restoration project." In the memo, the ASA(CW) concurs with the recommendation that the implementation of setback levees are a necessary project feature of the recommended plan to mitigate for induced flooding, and without moving the levees, minimal to no restoration benefits are achievable that meet the planning objective.
Implementation Guidance for Section 125(a)(2)(C) of the Water Resources Development Act of 2020, Beneficial Use of Dredged Material (2022)
Section 125(a)(2)(C) of the Water Resources Development Act (WRDA) of 2020 amends Section 204(d) of WRDA 1992 (33 U.S.C. 2326(d)) to authorize the Secretary of the Army for Civil Works to use funds appropriated for construction or operation and maintenance of a project involving the disposal of dredged material when selecting a disposal method that is not the least cost option based on a determination that the incremental costs of the disposal method are reasonable in relation to the environmental benefits or the hurricane and storm or flood risk reduction benefits. This memorandum provides guidance and direction on implementation of Section 125(a)(2)(C) and rescinds and replaces the implementation guidance for Section 1038 of the Water Resources Reform and Development Act of 2014.
