Two of the wettest rain gauges in the entire May 2010 flood sat just northeast of Brentwood. Observers there logged 17.15 and 17.07 inches, among the dozen highest totals the National Weather Service recorded across Middle Tennessee. Eleven years later, in March 2021, Brentwood measured 8.16 inches in another historic storm, and the Little Harpeth River gauge at Granny White crested at 16.20 feet in the early morning hours.
Those numbers matter in a city that has grown from about 4,100 people in 1970 to more than 45,000 in 2020, much of it in larger homes on rolling lots. The Restoration Job is not a contractor and has no crews of its own.

The Little Harpeth River and Hillside Drainage
The Little Harpeth River runs through Brentwood, including the Deerwood Arboretum and Nature Area with its man-made lakes and trails, and continues north into Davidson County as a tributary of the Harpeth. The city sits around 745 feet above sea level on rolling terrain, so heavy rain moves downhill fast. Homes at the bottom of a slope, beside a drainage swale or near the river and its feeder creeks are where water shows up first.
On a hilly lot, water often enters through a lower level rather than the front door: a walk-out basement, a window well, a garage slab that slopes toward the house or a crawl space vent. Clearing gutters, extending downspouts and keeping swales open are the simplest defenses, but they will not stop an 8-inch rain. When water does get in, water extraction needs to happen quickly, before it wicks up drywall and into cabinetry.
Dixie Alley Tornadoes and Roof Leaks
Brentwood lies within Dixie Alley, the part of the South with a high risk of destructive tornadoes, and the period from November through May carries the greatest danger. Tornadoes struck the area on December 24, 1988, January 30, 2013 and March 1, 2017.
Wind damage turns into water damage when rain follows through a torn roof or broken window. The first priorities are safety, then a temporary cover over openings, then photographs. Attic insulation that gets soaked rarely recovers and usually has to be replaced, and wet ceiling drywall can sag and fall. A provider offering storm damage cleanup can tarp, remove debris and start drying the interior in one visit.
Larger Homes, Bigger Leaks: Finished Basements and Second-Floor Laundry
Bigger floor plans mean a single failed supply line can spread water across several rooms before it is found, especially when it starts upstairs or behind a wall. Common sources in larger homes include second-floor laundry rooms, multiple water heaters, ice-maker and wet bar lines, and irrigation or pool equipment near the foundation.
- Know where your main shutoff is and make sure it turns freely.
- Check water heater pans and drain lines once or twice a year.
- Look at ceilings below bathrooms and laundry rooms for stains.
- For long trips, consider shutting off the main and draining lines in winter.
Finished basements need special attention. Carpet, pad, insulation and drywall at floor level hold water, and moisture can hide behind built-ins. Restoration crews typically remove baseboards and drill or cut low on walls to dry the cavities properly.
Humid Summers and Mold in Brentwood Basements
Middle Tennessee summers are hot and humid, and a wet basement or crawl space in July can start growing mold in a matter of days. Drying quickly prevents most of it. That means air movers, commercial dehumidifiers and moisture checks until materials are back to normal readings, not just a few fans and an open window.
If a musty odor lingers after a past leak, or stains reappear on drywall, have it checked. Mold remediation deals with both the growth and the moisture problem underneath it.
Flood Maps, Insurance and Who to Contact
Brentwood operates a stormwater program under the state's Phase II MS4 permit, and the city's engineering department takes stormwater questions at stormwater@brentwoodtn.gov. To see whether your address is in a mapped flood zone, search it on FEMA's Flood Map Service Center. Flooding from rising water is not covered by standard homeowners policies, so properties near the Little Harpeth or other creeks may want to look at separate flood insurance.
Neighboring communities faced the same storms. Our Franklin page covers the Harpeth River side of Williamson County.

Common Questions
How much rain did Brentwood get in the 2010 and 2021 floods?
In May 2010, two observation sites northeast of Brentwood recorded 17.15 and 17.07 inches, among the highest totals in Middle Tennessee according to the National Weather Service. In the March 27 to 28, 2021 flood, Brentwood measured 8.16 inches, and the Little Harpeth River gauge at Granny White crested at 16.20 feet.
My basement in Brentwood took on water during a storm. What should I do first?
Make sure power to the basement is off or that no outlets or cords are in the water. Photograph everything, then start removing water and moving belongings to dry ground. Water that entered from the yard or a creek should be handled as dirty water. Carpet, pad and wet drywall in a finished basement usually need to come out so the wall cavities can dry.
Does Brentwood have tornado risk that affects water damage?
Yes. Brentwood is in Dixie Alley, where destructive tornadoes are a real risk, especially from November through May, and tornadoes struck the area in 1988, 2013 and 2017. Roof damage from wind often leads to interior water damage when rain follows, so tarping quickly and drying the attic and ceilings matters.
Who do I contact about drainage problems on my street?
Brentwood's engineering department handles the city's stormwater program and accepts questions at stormwater@brentwoodtn.gov. Water inside your home is a separate matter; for that you can call (888) 317-9980 to be connected with an independent restoration provider.
