Well, then your problem is compounded, isn't it? Because you are going to
have to dig down to the pipe to remove it, and aren't going to be able to
reuse the fill over it, right? So you will need to fill with material all
the way down to the bottom of the pipe. Or are you somehow going to be
able
to reuse the material?
