Welcome! The City of West Des Moines has created this web page for citizens to use to gather information regarding the recent Flood Insurance Rate Maps (FIRM) revisions proposed by the Federal Emergency Management Agency (FEMA). We hope you will find this information helpful as you look to see how the new maps will affect your property.

The City of West Des Moines participates in the National Flood Insurance Program (NFIP) sponsored by FEMA so that property owners within the City are eligible to purchase federally backed flood insurance. Lenders and insurance companies use the FIRMs as a tool to analyze the risk of flooding to any individual property. The updated maps were prepared with the most current digital aerial mapping, allowing FEMA to more accurately predict areas that may be subject to flooding. As a result, several theoretical flood limit boundaries have shifted.

If you believe your property may be impacted by the new proposed flood limit boundaries, please consult our mailing list and a letter that was sent to West Des Moines residents potentially affected by the proposed mapping revisions.

The City of West Des Moines has also created an interactive mapping application for your use. Links to the respective FIRMs are included with this mapping tool. If you find this mapping application difficult to use or need some general advice on how to use it more effectively, please read our Helpful Hints document.

View the map index provided below (190231IND0A for 2006 or 19153CIND0A for 2016) to find out which map(s) apply to your property. Once you’ve found the pertinent map(s), click on the link to the FIRM that applies to your property for further information.

If you currently have an effective Letter of Map Amendment (LOMA) or a Letter of Map Revision (LOMR), both considered Letters of Map Changes (LOMCs), reference the preliminary Summary of Map Actions (SOMA). Properties with recorded LOMCs have also been mapped and can be viewed using the interactive mapping application. If the LOMC is listed as Not Incorporated, it has not been included in the mapping revisions but will be revalidated free-of-charge one day after the revised FIRMs become effective. Other LOMCs listed as Superseded will no longer be in effect when the revised FIRMs become effective.

In a FEMA letter dated February 17, 2016, additional information on the Criteria for Appeals of Flood Insurance Rate Maps and Scientific Resolution Panels (SRP) was provided. 

Although the proposed FIRM maps have not been adopted, FEMA officials have said they are tentatively scheduled to become effective in 2016. Notice of the FEMA proposed flood hazard determinations for Polk County, Iowa and incorporated areas was published in the Des Moines Register on February 24, 2016 and March 2, 2016. A 90-day appeal period will end on May 31, 2016. Information on the appeal period and a public meeting conducted by FEMA will be posted on this page once FEMA notifies us. Consult our frequently asked questions document for more information.

Should you find that your property status has changed from earlier mapping or your property is now included in or near an area where there is identified flooding potential, you may want to consider contacting your insurance agent and/or your lender to discuss the flooding risks. If you believe your property is not subject to flooding, you may want to file an appeal with FEMA.
