General Information

Ogden Valley Sheet Flow Map

Ogden Valley Sheet Flow

This map was developed from visual observations of sheet flow flooding that occurred on February 20th 1986. The map was created to help assist county staff and the public address potential flood issues. This map is not intended to be all inclusive of flooding that took place on this date. Other areas of the Ogden Valley may have also experienced flooding or have the potential of flooding but were not observed. This map is used in addition to FEMA floodplain maps.

General Flood Hazard Boundary Information

Weber County participates in the National Flood Insurance Program (NFIP). The program was created by the Federal Emergency Management Agency (FEMA) in an effort to improve public safety, prevent property damage, and protect the natural floodplain environment. Communities that participate in this program agree to manage flood hazard areas by adopting minimum regulatory standards. Weber County has adopted these standards by enacting ordinances which regulate development within Special Flood Hazard Areas (SFHA). For more information on what ordinances have been enacted by Weber County, please contact the Weber County Planning Department or the Weber County Engineering Department. Currently, SFHAs can be viewed on maps called Flood Insurance Rate Maps (FIRMs) published by FEMA.

Flood Insurance Rate Maps (FIRMs)

The purpose of a FIRM is to show the SFHAs in your community. SFHAs are areas determined to be inundated by a 100 year flood. FIRMs can be viewed or obtained from a variety of sources. You can view and/or download scanned versions of a FIRM at FEMA's web site, or view FIRMs for the Unincorporated Weber County areas at the Weber County Engineering Office (Public Works Department). You can also view an UNOFFICIAL digital version of the FIRM(s) by clicking on the provided link below (please read the disclaimer).

How the NFIP and determined flood areas may affect You

Currently, all proposed developments in the unincorporated Weber County Areas are reviewed by the Weber County Engineering Department for possible flood hazards. Any structures, fill, or other disturbance within a SFHA requires a floodplain development permit, and in some cases, a elevation certificate as well. Both are available at the Weber County Engineering Office. Mortgage lenders may be required to determine if a property they are financing is located in a 100 year floodplain or a "Zone A" SFHA on a FIRM. With this information, a mortgage lender can require a buyer to obtain flood insurance. Owners should be aware of how their property may be effected by SFHAs or other possible flood hazards in order to improve their safety and protect their property.
Please be aware that at the time each SFHA was determined, FEMA used the most accurate information available. However, due to limitations in topographic map definition and scale, as well as the placement of fill or other alteration of the land after a FIRM publication, structures or property may be inadvertently or unnecessarily included in a SFHA. For such situations, the Property Owner may apply for a Letter of Map Amendment (LOMA) or a Letter of Map Revision - based on Fill (LOMR-F). For more information please contact the Weber County Engineering Department or visit FEMAs LOMA / LOMR-F Tutorial Series.
Please Note:
FEMA does not allow government entities to make flood hazard determinations except as necessary to administer its floodplain ordinances. Weber County Engineering Department will try to be as helpful as possible with any questions. However, Weber County will not make insurance determinations.
