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 town.

The area is subject to flooding from the Trempealeau River, as well as from both creeks.  The part of town 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 requested a Section 205 study on June 5, 2013.  A federal interest determination was completed in July 2015.  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.  

The Corps and the local sponsor have agreed to a tentative plan.  The plan includes levees, floodwalls, channel modifications, closure structures, relocations and/or buyouts.  The plan may require the city of Arcadia to construct portions of the flood risk management system independently in order for the rest of the project to be constructed under the Section 205 program.  A draft report will be available for public review in 2019.  The study will be complete in 2020.


Section 205 of the Flood Control Act of 1948, as amended.


The first $100,000 of Section 205 study costs, used to complete the federal interest determination and develop the study plan and cost share agreement are not cost-shared.  The remaining study costs will be cost shared 50/50 between the federal government and the city of Arcadia.  The estimated cost to complete the feasibility study is $1,522,000. 

Under the Section 205 program, up to 65 percent of the design and construction costs are provided by the federal government.  The total federal investment in the project is limited to $10 million, including the initial $100,000 investment in the federal interest determination.  

The non-federal share of design and construction will be a minimum of 35 percent but it may be as higher depending upon the costs of lands, easements, rights-of-way, relocations and disposal areas necessary for the project, which are the responsibility of the local sponsor.
