FIGURE 1 - Procedure for Implementing the NPS Floodplain Management Procedural Manual

Summary

This manual establishes National Park Service (NPS) procedures for implementing floodplain protection and management actions in units of the National Park System as required by Executive Order 11988, “Floodplain Management,” and Director’s Order #77-2, “Floodplain Management.” It replaces all previous NPS floodplain management guidance and related instructions.

It is NPS policy to preserve floodplain values and minimize potentially hazardous conditions associated with flooding. To implement NPS floodplain policy, proposed actions are classified into one of three action classes. Depending upon the action class, one of three “regulatory floodplains” applies (100-year, 500-year, or Extreme). If a proposed action is found to be in an applicable regulatory floodplain and relocating the action to a non-floodplain site is considered not to be a viable alternative, then flood conditions and associated hazards must be quantified as a basis for management decision making and a formal Statement of Findings (SOF) must be prepared. The prepared. The SOF must describe the rationale for selection of a floodplain site, disclose the amount of risk associated with the chosen site, and explain flood mitigation plans. The SOF will generally be available for public review and comment by including the SOF in applicable National Environmental Policy Act compliance documentation.
