FEMA Revised Floodplain Appeal Period

Layton City has received a letter from FEMA stating the appeal period will start after the second publication of the “notification concerning the appeal process” in the Standard Examiner and the Davis County Clipper, scheduled for October 9 and 16, 2014.   During the 90 day appeal period all comments concerning the proposed preliminary maps completed by URS for FEMA should be submitted to Layton City to be included with our appeal submittal completed by Bowen Collins.

A copy of the FEMA letter and other attachments to their letter is linked under "Documents."  Engineering will be working closely with our consultant, Bowen Collins, to assure our appeal submittal meets the requirements outlined by FEMA.  Once the 90 day appeal period closes the “Community Consultation” period starts which will include dialogue between Layton City and FEMA regarding the scientific data submitted with our appeal.  The city also has the option of requesting a “Scientific Resolution Panel” to review our appeal which is an “independent third party review of the information to ensure the Flood Insurance Rate Maps are update correctly”.

Please let me know if you have any questions or concerns regarding the attached data.  We will inform you of any significant updates through the appeal process.

FEMA Floodplain Appeal Meeting Rescheduled

The Appeal meeting on April 9, 2014 has been rescheduled to April 23, 2014 at 6 pm.

Layton City has reviewed the preliminary Flood Insurance Rate Maps (FIRM) and the associated backup data provided by the State of Utah and FEMA.  Layton City intends to appeals the new maps based on the following criteria:

-Layton City has over 20 regional storm drain detention ponds that are used to reduce the downstream peak flow.  The FEMA study only include 2 of the detention ponds

-The hypothetical storm that was used in the FEMA study is not standard for this part of the country.

It is our recommendation that FEMA incorporate all of the regional detention basins and use a hypothetical storm that was developed for this part of the country.  We believe those changes will greatly reduce the flood discharge flow rate and the associate floodplain delineation.

Layton City has hired Bowen Collins & Associates, Draper, Utah to revise the hydraulics and hydrology studies using the recommended criteria noted above.  We believe the maps generated from the study by Bowen Collins will represent the most up-to-date and accurate information for Layton City.

An appeal meeting is scheduled for April 23, 2014 at 6 pm in the City Council Chambers at the Layton City Center.  Residents are encouraged to attend to view the maps and make comments. The revised maps will be submitted as a formal appeal to FEMA along with any appeals and protests received from the public regarding the preliminary flood insurance rate maps.

FEMA Revised Floodplain - Updated map link

We have discovered the link that was given to you to use in your postcards is now broken. FEMA is aware of the situation and tried to fix the link that was used, unfortunately the only option is to give you a new link. We are so sorry for the confusion. Please use this new link:

Also, the easiest way to be sure that you can always find the correct map is to go to:  and search the map name (i.e. Davis County)

FEMA Revised Floodplain

The Federal Emergency Management Agency (FEMA) is in the process of updating the Flood Insurance Rate Maps (FIRMs) for Davis County.  In conjunction with this effort FEMA developed a revised floodplain for Layton City. The revised maps may impact your property. If your property is found to be located within the 1-percent-annual-chance floodplain you will be required to purchase flood insurance.

                A Public Open House will be held on March 26, 2014 from 5:00 to 7:00 PM with a short presentation at 6:00 PM in the Layton City Council Chambers, 437 N. Wasatch Drive, Layton, Utah.  During this meeting the revised FEMA mapswill be discussed and those in attendance will have an opportunity to ask questions about the impacts the new maps will have on their property.

                A web viewer has been created to show the preliminary data and changes since the last FIRM data. You are able to look up your property to access data that is available for this project. Please visit the link provided to access the web viewer:  Use the "Basemap" button and select "Imagery" to view aerial photography.
