Corps of Engineers to host public meeting for Upper Joachim Creek Floodplain Management Plan

Published June 6, 2019

ST. LOUIS – The U.S. Army Corps of Engineers, St. Louis District, will host a public meeting to present the draft findings of the Upper Joachim Creek Floodplain Management Plan on Thursday, June 20, 2019, at De Soto High School, 815 Amvets Drive, De Soto, MO 63020, from 6:00 to 8:00 p.m. 

The meeting will include an overview of the Upper Joachim Creek Floodplain Management Plan, including preliminary findings and recommendations. After the presentations, subject-matter experts from the National Weather Service, United States Geological Survey, State Emergency Management Agency, FEMA, and the Corps of Engineers will be available to answer your questions.

“The Corps of Engineers and our partners are committed to enhancing public safety,” said Col. Bryan Sizemore, St. Louis District commander. “This floodplain management plan will provide the community with flood damage reduction strategies that consider a wide variety of mitigation alternatives.”

The floodplain management plan considers primary strategies to modify human susceptibility to flood damage and disruption through floodplain and floodwater management recommendations such as land use regulations, flood risk awareness and communication, flood damage reduction measures informed by a partial nonstructural assessment, as well as potential funding sources for implementing the recommendations.

When comparing FEMA’s 2006 Flood Insurance Rate Maps (FIRMs) and the draft 2019 updated FIRMs, the overall watershed shows a nearly 30% increase in the 1-percent Annual Chance of Exceedance (ACE) floodplain.  Of the total 2,127 acres (2019 FIRMs), 375 acres (17.6%) are within the De Soto city limits.
