After 13.57 Inches: The 2010 Flood and Nashville Foundations
Plenty of Nashville houses standing today went through the first weekend of May 2010. Some were flooded outright; many more sat in saturated ground for days. Here is what the official record shows, and what it means for a foundation.
On May 1–2, 2010, 13.57 inches of rain fell at Nashville International Airport, more than double the old two-day record of 6.68 inches (NWS Nashville). Creeks set record crests and Davidson County received federal disaster aid (FEMA). Soaked soil can wash out fill and load basement walls, so flood-era houses deserve a careful look.
What the record shows
- Rain: 6.32 inches on Saturday, May 1, the second-highest day on record at the airport, then 7.25 inches on Sunday, May 2, a new single-day record (NWS Nashville).
- The Cumberland: the river at Nashville rose to 52.55 feet, cresting May 3, against a flood stage of 40 feet (NWS Nashville).
- Creeks: Mill Creek at Woodbine set a record crest of 21.37 feet, and Richland Creek crested at 19.99 feet, almost five feet above its 1979 flood level (NWS Nashville).
- Aid: Davidson County was designated for individual assistance under disaster declaration DR-1909, declared May 4, 2010 (FEMA).
What floodwater does to a foundation
Standing water and saturated soil work on a house in several ways. Water-logged backfill presses hard on basement walls, which can crack or bow a block wall. Moving water can scour soil from under a porch, a slab edge or a shallow footing. Crawl spaces that flooded may have had wood sitting wet for days, which can weaken joists and sills long after the water left. None of this always shows right away.
If you're buying a house that stood through it
- Ask the seller whether water entered the house or crawl space in 2010 or since, and what was repaired.
- Look for tide lines on basement walls, newer drywall low on walls, or replaced subflooring.
- Check whether the lot lies near a creek or in a mapped flood zone.
- In the crawl space, look at the bottom of the joists and the sill plate for old staining or soft wood.
Not every crack is flood damage
Fifteen years on, most foundation problems in Nashville come from ordinary rain, not that one weekend. The city still averages 50.51 inches a year (NOAA), and a bad downspout does damage slowly. For water coming in, read about basement waterproofing in Nashville; for cracks that keep growing, see foundation crack repair. Typical prices for both are in the 2026 Nashville cost guide.
