How it works

Floodplain permit pre-application check, from one answer

  1. Pin the site and say what you're building.
  2. ePlan reads the flood map and ground elevation. A surveyor's certificate and your floodplain administrator decide.
  3. Read the free check. Filling a stream or wetland? Start a nationwide permit PCN draft.

Questions

Floodplain Development Permit: what people ask

Will the community ask for my other permits?

Yes. Communities must require permits for all proposed development in flood hazard areas and review that all necessary federal and state permits, including Clean Water Act Section 404 permits, have been obtained.

How high must a new home be built?

In zones A1-30, AE and AH, new construction and substantial improvement of homes must have the lowest floor, including the basement, at or above the base flood level, unless FEMA has granted the community a basement exception.

Can I build in the floodway?

Only if hydrologic and hydraulic analyses, done to standard engineering practice, show the encroachment would not increase flood levels in the community during the base flood.
