Flash flooding closes roads, floods basements in Union County
Hartleton 911 reported flooded basements and closed roads as heavy rain covered Routes 36 and 417, Honey Run Road and Slate Creek Road.

Flash flooding in Hartleton pushed water into basements and shut multiple roads after heavy rain swept across State Routes 36 and 417, County Route 68 at Honey Run Road and Slate Creek Road late on Aug. 2. The Hartleton 911 Call Center reported the flooding as emergency managers tracked the storm’s impact across Union County.
At 9:41 p.m. EDT, emergency management reported heavy rain over those roadways, a sign that the storm was hitting some of the same low-lying stretches where water can collect fast and cut off access. The closures added immediate problems for families trying to get home and for responders who may have needed to move through the area while roads were covered.
A FOX 56 post said the National Weather Service in Greenville-Spartanburg had issued a Flood Warning for northeastern Union County until 10:15 a.m. EST. The same post said public flooding was causing major issues in Union County that evening and warned drivers not to cross water-covered roads, a precaution that mattered in Hartleton as basements took on water and more than one route went under.

The storm also sharpened the financial damage for homeowners. Flooded basements can leave residents facing cleanup bills for water removal, damaged drywall and flooring, mold growth, and possible sewage contamination if drainage systems back up. Insurance can become another headache, since many standard homeowners policies do not cover flood damage, leaving families to sort out what is protected and what is not.
Union County’s Hazard Mitigation Plan Update, prepared for the Union County Commissioners in Lewisburg by Michael Baker International in 2020, shows the county has already mapped flood risk as a recurring concern. The Hartleton roads hit in this storm, including Routes 36 and 417, County Route 68 at Honey Run Road and Slate Creek Road, highlight the kind of repeat problem that mitigation planning is meant to reduce before the next round of heavy rain arrives.
