Box Elder Coyote Run

October 4, 2016

Urban Drainage and Flood Control District (UDFCD) works with the Federal Emergency Management Agency (FEMA) and local governments to get locally developed Flood Hazard Area Delineation (FHAD) studies incorporated into the FEMA Flood Insurance Rate Maps (FIRMs). A Risk Mapping Assessment and Planning (Risk MAP) project that uses the Physical Map Revision (PMR) process revises the FIRMs. The FHAD had been produced to identify and update flood risk potential and floodplain boundaries in the Box Elder Creek watershed.

Two streams in the Box Elder Creek watershed are being revised:

Box Elder Creek (Downstream of Jewell Avenue)
Coyote Run

Getting the FHAD information on the FIRMs help residents and business owners make informed decisions about personal safety and protecting financial assets. Having current flood mapping also allows community planners, local officials, engineers, builders and others to make determinations about where and how new structures, subdivisions, developments, and redevelopments should be built to reduce risk of flood damage.

Preliminary Flood Insurance Rate Maps (FIRMs) for the Box Elder Creek and Coyote Run PMR project are now available.


Here is a list of materials that can help you learn more about the studies and their potential impact on your property. You can also view proposed flood mapping changes with this link:
