Flood Emergency FAQ
1. Should I contract with disaster relief contractors and will the City pay for it? These contactors can be very helpful during a crisis but there is no garantee that the City or FEMA will cover the cost.
2. Will the City pick up the damaged material I need to remove from my home? No program exist for every flood event. Public disposal pick up and dumpsters will be determine by City officials on a case by case basis.
3. How do I file a damage claim with the City? Contact the Stormwater Division 801-208-3152

Properties that encroach or are in designated Special Flood Hazard Areas (SFHA) indicated by the Flood Insurance Rate Map (FIRM) Zones A, AE, A1-A30, AH and AO who plan to develop or fill a property designated as SFHAs are obligated to NFIP regulations and must file a Floodplain Development Permit Application.

Generally, this means the NFIP applies to property owners who plan to build structures, place fill, even place non-fixed structures into any part of a SFHA.

This page is intended to provide overall instruction but does not replace the specific requirements of ordinance and NFIP requirements.

FEMA Floodplain Development Permit Application

Projects encroaching into non-FIRM floodways must file for a Floodway Encroachment Permit.
Flood Control Encroachment Permit Application

Property owners who are occupying or developing in SFHA’s could be involved in one or more of the following three documents. These documents may be used to remove your property from the SFHA or reduce the flood hazard potential affecting your property. In each case, encroachments are not allowed to shift the SFHA to properties not previously in the SHFA or increase the flood risk to properties already in a SFHA.
