Floodplain Information

The unincorporated portion of Linn County has a history of flooding due to its location in the watersheds of both the Cedar and Wapsipinicon rivers. Being prepared is the best defense against major flood events.

What should you do before a flood?

  • Purchase flood insurance on your property. Flooding is not covered by a standard homeowner’s insurance policy. A separate flood insurance policy is required to cover damages incurred by flooding. Coverage is available for the building itself as well as for the contents of the building. Unincorporated Linn County participates in the National Flood Insurance Program (NFIP) that makes available federally backed flood insurance for all structures, whether or not they are located within the floodplain. Contact your insurance agent or visit the Cedar Rapids Public Library for more flood insurance information.
  • Maintain drainage channels and keep culverts free of obstructions and debris. Keeping drainage channels free of obstructions helps to reduce flooding in the event of heavy rains. The Linn County Secondary Road Department has an “Adopt-A-Roadside” program that allows individuals and organizations the opportunity to improve the quality of the road rights-of-way and/or drainage channels.
  • Protect your property from the hazards of flooding and wind. If the floor level of your property is lower than the “Base Flood Elevation” (elevation of the 100-year flood, based on the FEMA maps), consider elevating your structure, if possible. Brochures discussing flood proofing and other mitigation measures are available in the Cedar Rapids Public Library and the Linn County Planning and Development office. If a flood is imminent, property can be protected by sandbagging areas subject to the entry of water into living spaces. Linn County Secondary Road Department 319-892-6400, has coordinated with Linn County Emergency Management, 319-892-6500 to provide sand and bags at various locations in the county prior to flooding events. 
  • Meet permitting requirements. All development within the unincorporated portion of Linn County requires a permit. Always check and fulfill permitting requirements with Linn County Planning and Development at 319-892-5130; the Linn County Road Department for entrance, E-911 and right-of-way (R.O.W) work at 319-892-6400; or Linn County Public Health for well and septic permits at 319-892-6000 before you build on, alter, fill, or re-grade on any portion of your property and/or within any easement or right-of-way. Also, contact any of the numbers above to report any suspected permitting violations.
