Answer: You have certainly done your homework, and, frankly, you know more about the problem than I do. I looked at that PDF you mention and there's quite a bit of info there -- thank you for passing it along. My only suggestions would be
--to consider hiring a professional landscape contractor (who can applied the restricted herbicides)
--try to modify the habitat, such as removing lower limbs to allow more sunlight to reach the lawn
--consider alternatives, such as covering the area with landscape fabric and decorative mulch.
I'm sorry I can't be of more help to you on this one.
