Purpose

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

Location

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.

Description

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 the 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 and the U.S. Army Corps of Engineers completed a feasibility study in August 2020. The Corps and the city of Arcadia signed a project-partnership agreement on Feb. 1, 2021. The Corps began design of Reach 1 in June 2021. The project includes levees, floodwalls, channel modifications, closure structures, bridge, relocations and/or buyouts, engineered high ground and railway modifications. A contract for construction of Reach 1 is anticipated to be awarded in October 2025 dependent on sponsor real estate acquisition. Design of Reach 2 is starting in the fourth quarter of fiscal year 2024.
