2021 Updated Flood Insurance Rate Maps (FIRMs)

In 2015, the City of St. Charles elected to pursue the Seclusion option concerning an area affected by the decertification of the Boschert Creek Levee (a non-accredited levee system generally located between Boschertown Road and New Town Boulevard within Ward 8). The City selected this option due to the number of properties which would be required to obtain flood insurance based upon the decertification and to work with FEMA to more accurately study this area. The Seclusion option also allowed the City to move forward and adopt the other Flood Insurance Rate Maps (FIRMs) City wide (in review since 2009 and adopted in 2016).  

From March 2017 to present, City Staff from the Departments of Community Development, Engineering and Public Works have worked with FEMA officials to review the area affected by the levee decertification and identify the risk of flooding. After months of review, FEMA issued a Letter of Final Determination which indicated the FIRM’s must be approved by March 9th, 2021. In order to remain in good standing with the National Flood Insurance Program, the City has adopted the following approval schedule:

• January 5th, 2021 at 7:00 p.m. – Public Hearing and Introduction of an Ordinance before the City Council.

• January 19th, 2021 at 7:00 p.m. – Final Passage of the Ordinance before the City Council.

The new FIRMs  29183C0260H and 29183C0280H dated March 9th, 2021 can be viewed by using the link.

PLEASE NOTE: Letters to properties within 100 feet of the changed flood boundary have been mailed by the City.

The 100 foot buffer from the floodplain was chosen to insure proper public notification of the map changes. Please contact staff for more specific information regarding your property.
