Firefighters are protecting a line of communication towers from a brush fire that continues to burn in Makakilo and threatens two cabins and the Honouliuli Forest Preserve.

They include telephone, cellular, radio, TV, cable, Federal Aviation Administration and Navy communication lines, Capt. David Jenkins, Honolulu Fire Department spokesman, said.

The Makakilo blaze flared up over the holiday weekend. Ten fire companies, 26 personnel and a dozen Department of Land and Natural Resources’ Division of Forestry and Wildlife personnel continued to battle the brush fire Tuesday.

The Fire Department’s main strategy is to re-establish a road used as a fire break to allow state forestry and smaller HFD trucks to hold a line in protecting the towers, Jenkins said Tuesday.

Fire personnel also “pretreated foliage with a Class A foam designed to absorb heat and assist with extinguishment,” he said. “It keeps the fire from getting closer.”

Jenkins said conservative estimates suggests at least 1,025 acres have burned. The head of the fire is near the 2,000-foot elevation on the Kunia side of the Waianae Mountain Range.

Firefighters also used the foam in the area of a privately owned cabin at the 2,200-foot level on Palehua Road, which was also being used as an HFD command post, and another cabin.
