Grand Terrace landscaping company warehouse damaged in 3-alarm fire

GRAND TERRACE, Calif. (KABC) -- A warehouse belonging to a Grand Terrace landscaping company was heavily damaged following a fire.

The three-alarm blaze was reported at around 5:45 p.m. Monday in the 22000 block of Commerce Way.

At least 21 work trucks went up in flames along with roughly $1 million in other equipment and supplies.

It took San Bernardino County firefighters an hour to extinguish the flames, but not before roughly 90 percent of the roof collapsed and the walls were badly damaged.

Authorities said one firefighter suffered a minor injury.

There was no word on a possible cause.
