Solarizing, trying three different ways

I have a south facing full-sun lawn that I want dead. Well, I want the front yard dead too. I originally wanted to do cardboard, clear plastic, and black plastic on the south facing full-sun area to see how each does. I did try carboard on the small part of the yard by the hostas, but it has been breaking down and getting admittedly gnarly looking.
Additionally, my neighbor across the way AND my mother are both on the city council and bless them, have been swatting away complaints about the cardboard for weeks. Finally my mom showed up with the tarps and a lawnmower and we reached a compromise. The front yard can be next summer's botanical murder.
