Reduce the risk due to flooding in the city of Arcadia, Wisconsin.


Arcadia is located in Trempealeau County in west-central Wisconsin, approximately 130 miles southeast of St. Paul, Minnesota. The city is located on the Trempealeau River, with Turton Creek and Meyers Valley Creek flowing into the Trempealeau River on the east and west sides of the city.

The area is subject to flooding from the Trempealeau River, as well as from both creeks. The part of Arcadia located south of the Trempealeau River is affected by flooding, which includes the central business district, and Ashley Furniture Industries corporate headquarters and manufacturing facility. 
The central business district and Main Street were flooded in 2010, and a significant rainfall event occurred in July 2017, leading to damages along Turton Creek. Future flooding may result in direct damages and the possible loss of more than 4,000 jobs in the community. 
The city of Arcadia and the U.S. Army Corps of Engineers signed a feasibility cost share agreement on March 28, 2016. The feasibility study began in October 2016. A final report with an integrated environmental assessment was approved in August 2020. The proposed plan includes levees, floodwalls, channel modifications, closure structures, relocations and/or buyouts. The Corps and the city of Arcadia will sign a project partnership agreement in the fall of 2020, marking the start of the design and construction phases of the project .
Section 205 of the Flood Control Act of 1948, as amended.
Federal funding under the Section 205 program is limited to $10 million. The first $100,000 is for the determination of federal interest study, which is 100 percent federally-funded. The feasibility phase is cost-shared 50/50 between the federal government and the local sponsor. The design and construction phase is cost-shared 65 percent federal (up to the federal limit) and 35 percent local sponsor.

The following is the estimated financial breakdown of the three phases of the project.
