Guidelines and Standards for Flood Risk Analysis and Mapping Activities Under the Risk MAP Program

These guidelines and standards define the implementation details of the statutory and regulatory requirements for National Flood Insurance Program (NFIP) mapping. They describe how FEMA performs Flood Risk Projects, Letters of Map Change (LOMC), and related coordination activities. They are intended for mapping professionals and Cooperating Technical Partners (CTPs) under the Risk MAP Program.

The guidelines and standards are organized in a hierarchy. Standards are mandatory FEMA policy. They are divided into two categories.

Program Standards
Define important elements of the Risk MAP Program. Exceptions to program standards can be granted only by program leadership.

Working Standards
A required element of the Risk MAP Program, usually at a more detailed level than the program standards. Working standards are applied by specialists (engineers, planners, technicians, scientists, etc.) and generally have minimal ethical, political, and legal impacts to the program. FEMA Regional Offices may occasionally grant exceptions to these requirements.
