How to Read of Flood Map

Overview

A Flood Map, also referred to as a Flood Insurance Rate Map (FIRM), is an official representation of a community’s geography that outlines areas at risk of flooding and classifies them into specific flood zones. These maps play a crucial role in the National Flood Insurance Program (NFIP) by guiding floodplain management, supporting mitigation strategies, and influencing insurance policies.

The evergreen “How to Read a Flood Map” PDF tutorial from FEMA provides a helpful refresher on flood maps, flood zone designations, as well as a summary of related terms and tips for using the National Flood Hazard Layer (NFHL) Viewer.
