JURUPA VALLEY, CA —A fire erupted Wednesday in a large mulch pile on the perimeter of a warehousing district along the boundary separating Riverside and San Bernardino counties, burning less than a quarter acre as crews deployed to contain it.
The non-injury fire was reported just after 10 a.m. Wednesday at Brown Avenue and Wilson Street, at the northeastern edge of Jurupa Valley near the Santa Ana River bottom, according to the Cal Fire/Riverside County Fire Department.
Multiple engine crews arrived from the county, Cal Fire-San Bernardino County and the city of Riverside were sent to the location. There, they encountered flames moving slowly to the south despite gusting Santa Ana winds.
No structures were threatened.
Officials at the scene said that as of 10:45 a.m., the blaze remained within the mulch pile, but crews were establishing defensive lines in case the fire was spotted at the river bottom.
There was no immediate word regarding how it might have started.
