New Guidance on 2D Modeling

The "Managing Floodplains with 2D Modeling" guidance document is intended to give local officials who work with flood hazard data (e.g., floodplain managers, planners, and engineers) an idea of questions they might want to ask FEMA and/or its Mapping Partners throughout the RiskMAP process. It also outlines what to do with the information received and how to use it to manage development in the Special Flood Hazard Area.

Additionally, there is "1D vs. 2D Modeling" guidance that explains the difference between one-dimensional and two-dimensional modeling, and a "Community Role in the Mapping Process" document to help communities better understand the mapping process.
