The Turkey Creek flood risk reduction project in Kansas City is a significant endeavor that has taken over two decades to complete. This extensive initiative covers an urban area of 23 square miles that has historically faced severe flooding challenges. Notable floods in 1977, 1993, and 1998 caused catastrophic damage, notably along the Southwest Boulevard corridor and in the Central Industrial District of both Kansas City, Kansas, and Missouri. The 1998 flood alone inflected damages exceeding $12 million, disrupting life and threatening the economic stability of the region.
Importance of Collaboration
Lt. Col. John Myers, the deputy commander of the Kansas City District of the U.S. Army Corps of Engineers, emphasized the collaborative effort behind the project: “This project is a testament to what we can accomplish when we work together.” The dual threats posed by the Turkey Creek overbank flow and hillside runoff have continually jeopardized this vital economic area, which hosts over 800 businesses and more than 10,000 jobs. The comprehensive system established aims not only to minimize flooding risks but also to enhance the economic resilience of the region.
Integrated Flood Risk Reduction Features
The completed flood risk management project encompasses a series of interconnected features designed to alleviate flooding woes effectively. By addressing the dual threat of overbank flow from Turkey Creek and hillside runoff, this project enhances channel capacity and intercepts potential floodwaters. These features provide vital protection to more than $300 million in economic investments within the corridor.
Key components of the project include:
- Restoration of the historic 1919 tunnel spanning 2,000 feet at the creek’s terminus to improve water flow management.
- Urban channel modifications covering approximately two miles, involving walled, trapezoidal, and restored natural channels.
- Construction of levees to curtail residual flood risks effectively.
- Modifications for bridges, including the BNSF railroad bridges and the Mill Street Bridge to facilitate better water flow.
- A hillside interceptor system, comprising large pipelines designed to capture and redirect stormwater away from local streets before it impacts the Southwest Boulevard corridor.
- Environmental enhancements such as tree planting and a comprehensive flood warning system.
Years of Planning and Development
The groundwork for this extensive project commenced in 1998 when initial funds for preconstruction engineering and design were allocated. Authorized by the Water Resources Development Act of 1999, the project underwent modifications following a reevaluation driven by severe flooding in 2003. By December 2003, a report was submitted to Congress recommending the Locally Preferred Plan, and construction funding was appropriated starting in 2004, with an official Project Cooperation Agreement signed in 2006.
In May 2016, an increase in total project costs was recommended, leading to the reauthorization of the project under the Water Infrastructure Improvements for the Nation Act in December 2016. Full federal funding for the project’s completion was secured in 2020, paving the way for major construction contracts that have continued through 2025, marking a commitment to long-term flood risk reduction.
In conclusion, the Turkey Creek project represents a monumental achievement in flood risk management, showcasing the powerful results of collaborative efforts for community resilience and economic vitality. The commitment to enhancing water management systems sets a promising foundation for continued growth in the Kansas City area.
