The U.S. Army Corps of Engineers Los Angeles District, along with the Navajo County Board of Supervisors, signed the Little Colorado River at Winslow Flood-Risk Management Project Design Agreement July 11 at the Winslow Chamber of Commerce in Winslow. 

The signing ceremony marks the Corps’ initiation of pre-construction, engineering and design to reduce potential flood risk along the Little Colorado River in Winslow. 

“This has been a long-awaited event, not only for the county, but for the city of Winslow,” said Alberto Peshlakai, chairman of the Navajo County Board of Supervisors. “The purpose of this project is to eliminate the flood zone, protect the Santa Fe transcontinental train line, recognize Navajo/Hopi relocatees, and, most importantly, improve public safety for the city of Winslow.” 

About 5,000 people – families who live, work and call this area their home – along with critical infrastructure, including hospitals, schools, nursing homes and utilities, are located within a flood plain and are at the potential risk of flooding. The project area includes about 4.3 miles of flood-risk reduction levee and improvements located along the Little Colorado River near Winslow. 

“The completion of this project will be a win for this community – not only by reducing the potential flood risk associated with the river, but also by creating stability, economic vitality and future growth for the area,” Balten said. 

The Little Colorado River at Winslow Flood-Risk Management project received more than $65 million in federal funding from the Bipartisan Infrastructure Law to fund the project to completion. 

“The project is also very important to the nation,” Balten said. “Flooding also poses a threat to the Burlington Northern Santa Fe Railroad Bridge over the Little Colorado River – a critical transcontinental corridor for transporting goods to and from the Midwest to the West Coast.” 

Initial project work will focus on geotechnical and cultural updates, as well as refined hydraulic modeling.

“The Los Angeles District is dedicated to safely delivering quality projects on time to our Arizona partners and stakeholders,” Balten said.

The LA District supports the public and military in Arizona with a wide variety of projects and planning, engineering, construction and environmental services. Projects include flood-risk management, navigation, recreation, and infrastructure and environmental stewardship.
