Flood Insurance Rate Maps (FIRMs) and Flood Insurance Studies (FIS) have been created by the Federal Emergency Management Agency (FEMA) to show different degrees of flood risk for a community. Rates of risk help determine the cost of flood insurance. FEMA has provided Dallas County with FIRMs and FIS having an effective date of July 7, 2014. These maps are divided into a grid system known as panels
