Someone keeps parking in my spot?

Okay so I live on a street with only parking on one side of the road. I do not have a drive way, but the house across the street does. But they always park on the street across from my house. And it s gotten to the point where she will park in the driveway if I m there.But I ve NEVER done anything or said anything to her so it s not like she should be doing this in spite of me. Is there ANYTHING I can do?!
