Sixteen feet? I think your only two choices will be to: 1) have the trees
dug up by a professional, do the 16 foot fill, then have them replanted on
top of the 16 foot fill; or, 2) have the trees removed, do the fill, then
plant new trees. There is no magic way to bury a 20-foot tree with 16 feet
of fill and have it survive.

My yard tends to flood so I am raising the whole yard 16 feet by
having fill brought in. I had a company lift the house and put in a
new basement. I removed all the fences and posts. The filling has
begun. The problem are my trees. I thought that when soil was dumped
around trees, the trees would just rise to the soil level. It's not
working that way. I guess I need to add something to the trees. What
can I do to make the trees lift to the new soil level? I must have
dumb trees because they are only about 20 feet tall and if they stay
where they are, there will only be branches showing.
