Permit process

Floodplain permitting in Washington normally involves confirming floodplain status, securing any necessary environmental approvals, and obtaining building permits where work affects elevations, utilities, or finished ground grades. Applicants typically coordinate between DOEE for floodplain policy and the permitting office for construction approvals. Use FEMA flood maps to confirm base flood elevations and zone designations before applying. FEMA Flood Map Service Center[2]

  • Determine if property is in a mapped floodplain and identify the flood zone.
  • Prepare site plans, elevation information, and drainage or mitigation proposals as required by the reviewing agency.
  • Submit application materials to the relevant permitting office and to DOEE if an environmental floodplain review is required.
