What is the purpose of a Flood Insurance Rate Map (FIRM)?

The purpose of a Flood Insurance Rate Map (FIRM) is to document floodplains and special hazard areas. These maps are official FEMA documents that identify areas at risk of flooding and provide essential information used by insurance agencies in determining flood insurance rates. They play a critical role in urban planning, allowing local governments and communities to understand flood hazards and implement appropriate mitigation strategies. FIRMs also help residents and property owners make informed decisions regarding flood insurance and property development within flood-prone regions.

Options that suggest predicting irrigation needs, assessing drought areas, or outlining agricultural land do not align with the primary function of FIRMs, which is specifically focused on flood risk assessment rather than general land use or agricultural considerations.
