A quiet Folsom block turned into a minor disaster zone this weekend when a large sinkhole suddenly opened near a home, cutting into a yard and a strip of pavement and rattling nearby residents. Video recorded by neighbors shows the ground giving way, leaving behind a mud-ringed pit circled in yellow caution tape as people stand back and stare.
Neighbors told reporters the hole began to form during the weekend storms, as reported by CBS Sacramento. In the brief clip shared with the station, residents can be seen pointing at the crater and carefully surveying the damage from the edge.
Folsom Has Seen Drainage Trouble Before
City paperwork shows this is not the first drainage scare in town. In April 2025, crews responded to a sinkhole on Glenn Drive and traced the problem to a failing 24-inch corrugated metal storm drain pipe, according to a Folsom City Council staff report. Workers performed a temporary repair at the time, and that incident kicked off plans for a broader storm drain replacement project in the area.
Why Storms Can Hollow Out The Ground
The U.S. Geological Survey notes that sinkholes form when water strips away underground support, either by dissolving rock in karst landscapes or by eroding soils and the bedding around pipes that hold up streets and yards. Heavy rain, saturated ground and aging or failing stormwater systems all increase the odds of a sudden collapse, according to the U.S. Geological Survey.
What Residents Should Do
If you spot new depressions, sagging pavement or fresh cracks in the ground, keep people and vehicles away, then report the hazard or call 911 if anyone is in immediate danger. The City of Folsom's Public Works page lists contact information and reporting options, and the department's public works line is published there, according to City of Folsom Public Works.
Between neighbors' videos and the city's own records, the latest collapse is a pointed reminder that intense storms can expose weak spots in aging drainage systems. This story will be updated when local officials or repair crews release more details on the fix and the timeline.
