Steigerwald Wetland Restoration
- Curtis Loeb, P.E., Principal Engineer, Wolf Water Resources
- Wade Osborne, P.E., Senior Associate Engineer, Cornforth Consultants
PROGRAM ABSTRACT The Steigerwald Floodplain Reconnection Project was a collaborative effort across over a dozen federal, state, and local agencies to reconfigure the Columbia River levee system to reduce flood risk, reconnect 965 acres of floodplain, and increase recreation opportunities at Steigerwald Lake National Wildlife Refuge located in Washougal, Washington. The project removed 2.2 miles of federally-authorized (U.S. Army Corps of Engineers) levee, excavation of four large floodplain channels, and creation of 115 acres of new wetland habitat. To reduce flood risks for residents and infrastructure, floodplain reconnection required the design and construction of two new setback levees, 500 feet of new floodwall along Gibbons Creek, and raising a section of Washington State Route 14. Wolf Water Resources and Cornforth Consultants have partnered since early design in 2014 to the end of construction in 2022, overcoming numerous significant technical challenges along the way. The presentation will discuss these technical challenges and also highlight the numerous project benefits for fish and wildlife, for adjacent property owners, for the Refuge land manager, and for the levee system operator.

Portland Metro Levy System
Ryan Cahill, PE, Hydraulic Engineer, U.S. Army Corps of Engineers - Portland District
SUMMARY In 2018, the U.S. Army Corps of Engineers initiated a Feasibility Study focusing on Flood Risk Management of the Portland Metro Levee System in partnership with the Columbia Corridor Drainage Districts (CCDD) Joint Contracting Authority. The study area includes 27 miles of levees along the lower Columbia River within the Portland Metropolitan Area, running from Smith Lake to the Sandy River. The federal feasibility study process leads to a recommendation to Congress for federal investment in addressing the problem areas in the levees and drainage system. The three-year federal feasibility study process is now complete, culminating in the Chief of Engineers signing the Chief’s Report on August 20, 2021. This presentation will give a brief history of the feasibility study process and provide an overview of the recommended plan.
