"This integrated Feasibility Study and draft Environmental Assessment (FS/EA) has been prepared by the U.S. Army Corps of Engineers, Portland District (Corps) to develop and evaluate the feasibility of alternatives for the strategic placement of dredged material to restore and expand shallow water and scrub-shrub wetland habitat for fish and wildlife species in the Lower Columbia River estuary. This evaluation resulted in the recommendation of a Tentatively Selected Plan (TSP), also referred to as the “Proposed Action” for purposes of the National Environmental Policy Act of 1969 (NEPA). In accordance with regulations implementing NEPA, this FS/EA compares the environmental consequences of the alternatives, including the Proposed Action, and identifies a preferred alternative (the TSP/Proposed Action)." -- From the Executive Summary, page 5.

The purpose of this report is to present the results of the U.S. Army Corps and City of Portland Section Aquatic Ecosystem Restoration Feasibility Study undertaken to identify and evaluate alternatives for restoring important fish and wildlife resources at the City of Portland's Oaks Bottom Wildlife Refuge.
