A fire at an illegal marijuana cultivation site on the north side of Sage Wednesday scorched just under a half-acre before crews got it under control.
The non-injury blaze was reported at about 11:35 a.m. in the area of Sage and Red Mountain roads, roughly three miles southeast of Diamond Valley Lake, according to the Riverside County Fire Department.
The agency said multiple engine crews were sent to the location, preceded by a Cal Fire air attack boss in an observer plane and a water-dropping helicopter.
The chopper made several runs on the slow-moving fire, halting its forward rate of spread at 12:35 p.m., according to officials at the scene.
Firefighters completely contained the blaze just before 1 p.m. and were expected to remain at the location, mopping up, until 3 p.m.
A battalion chief overseeing operations requested sheriff’s deputies to investigate the illegal grow. There was no word on the number of cannabis plants under cultivation.
The cause of the fire was not immediately known.
Sage is an unincorporated community, and the Riverside County Board of Supervisors has not authorized any commercial cannabis farms there or in any other unincorporated area.
