FEMA Preliminary Flood Maps (FIRMs)
We will post updates to this webpage as information becomes available.
TIMELINE UPDATE 04/02/18: According to the Iowa DNR, the earliest we will receive the six-month notice of the finalized new maps will be June 2018. If this is the case, the new preliminary maps will become effective in December 2018. For LOMA-OAS, see below for when it will be possible to apply. We will continue to update this information as needed.Preliminary Flood Maps: Over the past few years, the Federal Emergency Management Agency (FEMA) has been refining, updating, and digitizing flood plain maps nationwide. Recently, FEMA has produced new preliminary Flood Insurance Rate Maps for the City of Urbandale based on the most recent data. In February 2016, FEMA published a Public Notice for these preliminary maps. This began a period in which communities and their citizens could review and appeal the preliminary maps. FEMA is now in the process of reviewing these appeals.
LOMCs: If you currently have an effective Letters of Map Change (LOMC), such as a Letter of Map Amendment (LOMA) or a Letter of Map Revision (LOMR), you may view these on the above web map. LOMCs listed as Not Incorporated have not been included in the mapping revisions, but will be revalidated free-of-charge one day after the revised FIRMs become effective. LOMCs listed as Superseded will no longer be in effect when the revised FIRMs become effective. If you have a LOMC that is not shown on our web map, please contact our office.
LOMA-OAS: For properties where the 100-year flood area touches the parcel but the building structure is clearly outside this area, the property owner may request a “Letter of Map Amendment – Out as Shown” (LOMA-OAS). PLEASE NOTE: At this time, you may apply for a LOMA-OAS only if the current effective map touches your property. For the new preliminary maps, a LOMA-OAS request cannot be submitted more than 60-days before the effective date of the new maps; as the effective date of the new maps is estimated to be December 2018, you will need to wait until October 2018 to file your LOMA-OAS.
