A fire broke out Wednesday evening in a new Jamestown subdivision, burning one home and damaging two others off Golf Links Road, north of Highway 108-49.

The first call about the blaze came in at 6:30 p.m., said Battalion Chief Kevin Patton with Cal Fire’s Twain Harte Battalion. The first firefighters on scene reported one structure fully on fire with immediate threats to two structures next door.

Columbia Air Attack pilots in two tanker planes and one helicopter responded with 11 engine crews, one ground crew, two water tank trucks and one bulldozer, Patton said.

About nine firefighters in the initial strike team, clad in heavy urban turnouts and self contained breathing rigs, turned hoses on the flames and knocked most of them down before 7 p.m.

The ruins of one home, fencing and other material still smoldered and smoked as Cal Fire law enforcement investigators arrived to try to determine the cause.

Battalion Chief Matt Gilbert and Officer David Fulcher said they could not discuss the new fire investigation.

Gilbert said there was still no cause determined in the Twist and Jacksonville fires that broke out within less than a mile of each other outside Jamestown on consecutive days in late July.

The new subdivision is called Boulders and it’s billed as “a collection of energy efficient homes that represent the best of Contemporary California Living,” according to literature handouts on a sign outside the gated subdivision.

The street address for Boulders is 10655 Golf Links Road.

Ron Hamilton, a resident of Tuolumne, said he grew up on the property where the fire happened Wednesday evening. His mother, who is 82, was reared there as well.

“This used to be my grandparents’ ranch,” Hamilton said. “My parents still live on property that joins the ranch."

Hamilton said when he arrived at his parents’ place, one house in the subdivision was “fully in flames, and ash and embers were falling everywhere.”

Apparently there had been some kind of explosion before he arrived, he said.

“My parents and their neighbors heard the explosion,” Hamilton said. “There was ash and embers falling all over my parents’ house. There were spot fires between the main fire and my parents’ place. Firefighters came and put out the spot fires and they’ve kept watch since the fire was put out.”

Hamilton said firefighters did an amazing job, because the house that burned was right in the middle of the new subdivision.

“It’s been very dry out here,” Hamilton said. “They did a fantastic job keeping it at one house.”
