Declaring a state of emergency lets Clackamas County officials ask for resources, evacuate people, barricade roads and redirect money for emergency use.

A reverse 911 was activated due to the blaze near South Unger and Bauer roads, alerting residents living in the area to leave their homes in the middle of the night.

Around 6 a.m., 40,000 PGE customers in Clackamas County were without power. By 2 p.m. that number was aboutu 27,000.

There are firefighters from Colton, Canby and Gresham helping battle the flames.

On Monday night, a blaze in Oregon City that was visible over rooftops started in an abandoned industrial building, according to Clackamas Fire officials.

The exact cause of the fire is unknown at this time, but it started in an abandoned building off of Agnes Avenue near the Clackamette Cove. From there, it spread to three other structures and then the surrounding land before firefighters were able to get the blaze contained. In total, four buildings were damaged and 12 acres were burned in Oregon City.

Fire officials said no evacuations were needed in relation to the fire.
