The Lawrenceburg levee is a United States Army Corps of Engineers (USACE) levee system, designed for over 500-year flood protection. The top of the Lawrenceburg levee is at 504', which converts to a Tanners Creek gauge river elevation of 79.7'.
The Greendale levee is a FEMA levee system, designed for 100-year flood protection. The top of the Greendale levee is at 493', which converts to a Tanners Creek gauge river elevation of
Below is a brief overview of what happens when the Tanners Creek water level reaches certain heights.

Also, while certain community organizations and volunteers will be needed to assist in this process, the LCD will supervise and manage ALL action during this time. Last, the below heights are based on SILL elevation, which is the level at which the flood water meets the bottom of the flood gate.
