Add a flood measure to record its inputs, capacity and governing check.

Learning objectives

  • Map flood hazard
  • Compare mitigation alternatives
  • Evaluate residual risk

Engineering judgment

  • No project eliminates flood risk; it redistributes it.
  • Check downstream impacts.

Governing standards

  • NRCS TR-55
