Commentary

Hey, Jason. Thanks for the report. I've been hearing about this patch of knotweed for a while, so it's nice to finally get a precise location. We don't do work on knotweed until late in the summer, but I'll definitely put this on my 'to do' list. If you have any questions, feel free to reach me directly at mitch.bixby@portlandoregon.gov. Have a good week....
