Guidance

Guidance documents provide vetted recommended approaches for FEMA's Risk Mapping, Assessment and Planning (Risk MAP) Program. These guidance documents support current FEMA standards and facilitate effective, efficient implementation of the program. All guidance documents were written to support FEMA standards and align with current regulations, but are not mandatory. Alternate approaches that comply with standards and support program objectives are acceptable.
