Description
Waverly, TN is a community of approximately 5,000 situated in the Trace Creek Valley along US Hwy 70 adjacent to Kentucky Lake in Middle Tennessee. On Labor Day weekend 2021, the region around Waverly received up to 15-inches of rain in 12 hours breaking a rainfall record for Tennessee. During the flood, debris accumulated upstream of a railroad bridge crossing of Trace Creek, resulting in a backed up volume of approximately 48 million gallons of water upstream of the City. Once the creek breached the railroad bed, a surge of water followed, devastating the City and claiming the lives of 21 people. The flood waters impacted over 500 homes, uplifting many structures from their foundations, with 271 being a complete loss. Waverly Elementary and Junior High Schools were both inundated with several feet of water, the Humphreys County 911 center was rendered inoperable, and debris was spread across the City. Additionally, ten bridges across the county were destroyed resulting in major transportation challenges. The City’s water infrastructure was heavily impacted by the floodwater with the water treatment plant, wastewater treatment plant, and public works headquarters all inundated. Additionally, all City support vehicles, equipment and supplies were lost thereby eliminating the City’s ability to respond to the event. Neighboring utilities responded by providing labor and equipment which was key to getting these facilities back up and running quickly. The U.S. Army Corps of Engineers is currently conducting a Floodplain Management Services Study of Trace Creek which will model the creek and evaluate mitigation measures. Alternatives include removal of a low head dam in the creek, channel modification, repositioning the flood plains and creating new retention structures as well as flow measurement and community notification systems. The results of the study will be presented in 2025. Following four years of recovery, the city is continuing to rebuild critical infrastructure damaged during the event. Further complicating the rebuilding process, the loss of homes has resulted in a loss of customers and a significant loss of water revenue for the City. This revenue shortfall has presented a challenge for the city as the list of capital improvements is extensive for the small community. Water infrastructure projects slated for funding in 2025 include Sanitary Sewer Evaluation Surveys (SSES), sewer rehabilitation, water main replacement, backup generators, chlorine contact basin replacement, and a new groundwater treatment facility. Recovering from the flood has led local leaders to evaluate many concepts and alternatives related to water resource management including building practices, land uses, asset management and the formation of a Humphreys County Water Authority to more efficiently manage water infrastructure within the county. This presentation will provide an overview of the event, rebuilding process, emergency planning, risk mitigation, funding, and implementing resiliency into the design of new infrastructure.
