This Public Notice announces the Section 408 review of the Columbia River Estuary Study Taskforce (CREST) Government Island Restoration project.
Portland District is reviewing CREST’s proposal to evaluate restoration actions, select of a set of preferred restoration actions, and develop the construction-ready design documents for implementation of the selected project to benefit juvenile salmonids, while balancing the Port of Portland’s (Port) existing mitigation requirements.
The Government Island Restoration project is being conducted by CREST in association with the Port.
Government Island is owned by the Port and Metro. Metro is the regional government, responsible for regional land use planning across the Portland metropolitan area, encompassing incorporated and unincorporated areas in Clackamas County, Multnomah County, and Washington County and that is responsible for regional land use planning. Government Island is managed under a cooperative agreement between the Port and the State of Oregon Parks and Recreation Department.
Habitats on the island include upland forest, riparian forest, grasslands, and freshwater wetlands. A sizable portion of the wetlands on the island are held as waterfowl habitat mitigation lands established in the mid-1990’s by the Port as compensation for filling of wetland areas adjacent to runways at Portland International Airport to eliminate bird-airplane hazards.
The Bonneville Power Administration (BPA) has provided grant funding to CREST in support of the feasibility and design tasks associated with the project.
Project purpose: The suite of restoration actions selected for the overall proposed project design include:
- Removal of a tide gated water control structure that currently excludes fish access from much of the floodplain interior habitats of Government Island;
- Installation of large wood to facilitate fish passage, herptile and beaver habitat enhancement, and maintenance of the Port’s waterfowl mitigation wetland acreage;
- Reconnection of a historical wetland swale along the upstream portion of the island to enhance fish and wildlife access and habitat function;
- Removal of invasive plant species and re-vegetation with a native plant palette specified by habitat zones (e.g. low to mid-elevation emergent marsh, high marsh, and riparian/upland); and,
- Enhancement of riparian and upland wildlife habitats through construction of hibernacula and habitat piles.
Alteration of a federally authorized project: This proposed project would modify a federal flood protection system (revetment) and therefore require authorization from the Corps, pursuant to 33 USC 408 (Section 408). Section 408 provides authority to the Secretary of the Army to grant permission for the alteration or modification of Corps federal civil works projects when, in the judgment of the Secretary, such alteration or modification will not be injurious to the public interest and will not impair the usefulness of the project.
Consideration of Comments: The Corps is soliciting comments specific to this project from the public, federal, state and local agencies and officials, and other interested parties. Comments will be considered in determining whether it would be in the public interest to proceed with this action.
All comments received will become part of the official record and are subject to public release under the Freedom of Information Act including any personally identifiable information such as names, phone numbers, and addresses.
Comments: Interested parties may submit, in writing, any comments directed specifically to this proposal and not to other regulatory processes administered by the Corps or other government agencies pertaining to the Government Island Restoration project.
Comments should refer to PM-F-Government-Island-Restoration-2019 and the date of this Public Notice (June 12, 2019), and be postmarked by the comment due date (June 27, 2019).
