Location/Description

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.

Status

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. A draft report will be available for sponsor review in late 2019. The study will be complete in 2020.

Authority

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

Fiscal

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 federally funded. The feasibility study costs are shared 50/50 between the federal government and the city of Arcadia. The estimated cost of the feasibility study is $1,680,000.

Under the Section 205 program, up to 65 percent of the design and construction costs may be provided by the federal government, with the total federal investment capped at $10 million, including the cost of studies, design and construction. The typical Section 205 project is less than $15 million. The estimated cost to design and construct the proposed Arcadia project is $29 million. The Corps is currently seeking a waiver from the Assistant Secretary of the Army for Civil Works to keep the project in the Section 205 program. The city of Arcadia would pay all costs in excess of the $10 million federal limit.

The non-federal sponsor must provide any lands, easements, rights-of-way, relocations and disposal areas necessary for the project, as well as provide the local share of costs for design and construction.
