A small grass fire that broke out Wednesday underneath Interstate 215 in Riverside was quickly knocked down before approaching homes and businesses.
The non-injury blaze was reported at about 2:40 p.m. along a retaining wall at Blaine Street and southbound I-215, according to the Riverside Fire Department.
Battalion Chief Brian Guzetta told City News Service that crews encountered flames in a grass strip, sending up a large amount of smoke but not threatening any structures.
Firefighters fully contained the blaze less than 10 minutes later.
The area is a known transient corridor, with homeless people camping and gathering there, and Guzetta said it was possible the blaze was a result of transient activity.
An investigation was underway.
