Read nothing here as legal, tax, insurance or engineering advice. The cost figures are national, each tagged with a source and year, since no Nebraska or Omaha cost source turned up. An actual price comes in writing from a contractor who has looked at the basement.

Rules on permits, licensing, sewers and plumbing change over time. When a page summarizes something published by the City of Omaha, its Public Works or Permits & Inspections offices, the Nebraska Department of Labor, the Attorney General or one of the towns, confirm it with that office before relying on it. The CSO Program and the sewer backup line belong to the City of Omaha, and each town runs its own sewer and permit offices. No public body endorses, funds or works with this site.

Rain and river figures cite the National Weather Service, USGS or the news outlet that reported them and are offered as background. Remarks about loess, glacial till and groundwater are general and describe no particular lot.

The cost calculator and the wet-basement checker give rough guidance only; neither one can see or diagnose your walls.

Whatever contractor receives a request is an independent business, responsible for its own estimates, workmanship and conduct. Advertising on the site is not an endorsement, and none is given. No homeowner pays this site or gets anything from it.

On insurance: a sewer backup is often outside a basic homeowner policy unless a rider or endorsement was bought, and flood damage falls outside standard homeowners coverage. Read your policy, ask your insurer or agent, and take general questions to the Nebraska Department of Insurance at (402) 471-2201. Nebraska law governs this disclaimer.
