The blaze, dubbed the Arlanza Fire, forced evacuations for residents living on Valley Drive between Misty Ridge Drive and Mitchell Avenue, the Riverside Fire Department tweeted shortly before 8 p.m.
The fire jumped the containment line and was burning in mulch. The blaze first erupted last Sunday and the fire department tweeted Wednesday morning that it was 90% contained, before it apparently flared up.
Valley Drive between Chadbourne Avenue and Misty Ridge Drive was also closed to vehicle traffic due to the blaze.
Just before 8 a.m. Thursday, all evacuation orders were lifted, though smoke may still be visible in the area.
The public was asked to avoid the area as firefighters continue to battle the fire.
Southern California will see increased fire danger for the next few days as a red flag warning is in effect for much of the region due to Santa Ana winds and dry conditions.
