The Santa Monica Fire Department assisted on the response to a brushfire that broke out Tuesday morning northwest of city limits.

One local engine carrying four firefighters and a deputy fire chief were on the scene off Pacific Coast Highway east of Temescal Canyon Road for about an hour, according to battalion chief John Nevandro.

No injuries, structural damage or evacuations were reported. The cause of the fire is under investigation.

SMFD supplied water and backup at the incident, which was listed at the 15500 block of Via de las Olas, south of Sunset Boulevard and west of Chautauqua Boulevard.

The Los Angeles Fire Department, which reported the blaze at about 11:45 a.m. Tuesday, had more than 80 firefighters as well as three helicopters at the scene. County fire hand crews also assisted.

The blaze was confined to less than an acre within an hour, according to the LAFD.

“They got a handle on it,” Nevandro said. “We really didn’t do a whole lot.”

Traffic was backed up Tuesday afternoon on PCH east of Temescal Canyon Road.
