Crews working on the Riverside fire are determining the best options for containing the fire as control lines are developed.
During a virtual meeting on Monday, Sept. 14, Operation Section Chief for Southwest Incident Team 1 Jeremy Human said the team is developing both primary and alternate models to determine the best options for containing the Riverside fire, which spans 134,575 acres.
Factors in the process include topography, infrastructure, the potential for spot fires, the ability to reach the fire perimeter and multiple other elements.
Clackamas Fire Chief Fred Charlton described the Riverside fire as one of "the most historic wildfires in the history of Oregon and certainly within Clackamas County."
"Our hearts and thoughts are with all of you," Charlton said. "These are stressful and overwhelming times. We understand how you have been impacted, but we are here for you 24 hours a day."
As of Sept. 14, approximately 400 personnel were working on the Riverside fire, and Southwest Area Incident Management Team Commander Alan Sinclair expected that number to increase.
"Part of my job is letting people know what we're dealing with on the ground, and what resources we need in our operations in order to meet that," he said.
Though crews have established fire lines, these are not equivalent to containment lines —
which is why the Riverside fire is described as 0% contained. Sections of a fire are only considered contained if there are no more hotspots near the fire lines.
"We've got a lot of good work being done out there. You're not seeing containment percentages yet, but that doesn't mean that work is not being done," Sinclair said. "We wait until we are fully confident that those lines will hold before we will say that they are contained."
