Information on Future Physical Map Revisions (PMRs)

The Mile High Flood District (MHFD) and the Federal Emergency Management Agency (FEMA) work together to incorporate locally developed Flood Hazard Area Delineation (FHAD) studies into the FEMA Flood Insurance Rate Maps (FIRMs). The FHAD studies have been produced to identify and update flood risk information and floodplain boundaries. The Physical Map Revision (PMR) is the FEMA process to update the FIRMs. Learn more about the PMR process and what that could mean for you and your property.


Everything you want to know about FHADs — from how they’re developed and how their data gets incorporated into the FEMA FIRM, to how the revised FIRM affects property owners and local regulations.
