Redwood Creek Estuary Restoration
Continuing Authority, Section 1135
PROJECT LOCATION AND DESCRIPTION
The Redwood Creek estuary is located in Humboldt County, CA. It is well documented that the Redwood Creek Federal levees have reduced the size, complexity, and ecological function of the Redwood Creek estuary, while exacerbating flooding and invasive species plant expansion in the agricultural lands behind the levees. This project represents a significant opportunity to restore hydraulic, sediment and floodplain processes necessary to restore and sustain ecological function in lower Redwood Creek. Such restoration is critical for improving critical habitat for ESA listed such as the Chinook, coho and steelhead salmonids as well as other fish and wildlife that are native to this watershed. These restoration opportunities have been studied by federal, state, and academic scientists and there is strong consensus that a restored estuary will directly benefit habitat for fish and wildlife. The Redwood Creek estuary also lies within the ancestral territory of the Yurok Tribe and has provided marine and freshwater resources to their people since time immemorial.
TOTAL COST $ 13,787,000
FEDERAL COST $ 10,000,000

TOTAL FEDERAL COST THROUGH FY 2022 $ 100,000
FY 2023 BUDGET $ 160,000
COST TO COMPLETE $ 9,740,000
FY 22 ACCOMPLISHMENTS
- The Federal Interest Determine (FID) report documented strong federal interest in proceeding to the costshared feasibility phase (28 March 2022).
- The Corps and Humboldt County are drafting a project management plan to support the feasibility cost sharing agreement that will be executed in summer 2023.
- Drafting of a public involvement plan to document the robust Tribal and stakeholder engagement necessary to support this project.
ISSUES AND OTHER INFORMATION
- The CAP 1135 authority is intended to improve existing USACE structures that have degraded the environment, for the purpose of the ecosystem.
- Engineering With Nature (EWN) principles will be leveraged to restore the estuary while meeting the flood risk management requirements related to the authorized project.
- Comprehensive benefits will be quantified to evaluate the effects of alternatives.
- 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. It is also the policy not to increase flood risks or decrease life safety.
- 2nd District, Rep. Jared Huffman
