Can landlords remove tenant's items that they keep leaving out?

[Ellie Narie]

I have some very problematic tenants. I already gave them quit notices and will be filing for an eviction soon. However, they keep leaving a pile of junk (boxes, furniture, etc) out on their driveway. Like, their whole driveway is literally their pile of junk, and it's all stacked. 

The problem is, their driveway is right next to the driveways of my other two tenants. And the pile of junk that the problematic tenants have left out makes it almost impossible for the other two tenants to get in their cars! 

This junk might also damage their cars, and it impedes into the driveways of the other tenants. 

Can I legally have this pile of junk removed immediately, without waiting for an eviction? In the state of Oregon.
