Overview of Floodplain Rules in Aurora

Floodplain management in Aurora implements the National Flood Insurance Program (NFIP) minimum standards and local ordinance provisions. Local standards set building elevation, fill limits, and site design requirements for properties in mapped flood hazard zones. Property owners should confirm the flood zone designation on FEMA maps and the City of Aurora planning resources before permitting or construction.

Key official resources include the municipal code chapter on floodplain regulations and the City of Aurora planning/building guidance pages. For FEMA map queries, consult the Flood Map Service Center to confirm effective panels for Aurora. Municipal code[1] City planning[2] FEMA maps[3]

Check FEMA panels early—mapping affects permit conditions.

Common Development Standards

  • Elevate new residential structures above the base flood elevation or follow local elevation standards.
  • Restrict placement of fill, storage, and critical utilities in floodways.
  • Use flood-resistant materials below the required elevation for remodels and repairs.
  • Maintain natural floodplain functions and avoid activities that increase flood risk to neighboring properties.

Mitigation Steps for Property Owners

Mitigation reduces damage and can lower insurance premiums. Common measures include elevating utilities, installing flood vents, relocating critical equipment above expected flood elevations, and using permeable landscaping to improve drainage. Engage a licensed surveyor or engineer to document elevations and to prepare permit drawings if required.

  • Obtain a flood elevation certificate after elevation or substantial improvement work.
  • Consider buyouts or voluntary acquisition programs if available in your watershed.
  • Contact the City of Aurora Building Division for pre-application guidance.
