I called the construction outfit yesterday.  he said there is 15-20
inches of soil over the TOP of the drainrock.  And I believe that the
design manual I have states that there can be up to 24" or so.  I was
going to have good (tho my soil is very good) soil with compost,
topsoil, peat and etc; etc; brought in to raise the level to the maximum
allowed.

Yes....but, there are 4 drain trenches, stretching from 35 to 65 feet in
length.  The island of untouched soil between the trenches might be able
to hold a small tree (Styrax japonica, or the styrax obassia that I am
holding which is about 8' tall and very well shaped.  Or perhaps the
Davidia that I am also holding for personal use.)
It's just that I want a very dimensional garden, with height and weight,
and it's very hard to do if the entire thing is restricted to perennials
and their limitations of height, not to mention the restrictions
encountered in view of the entire thing being in full sun, sans trees.

Grand Perk.  The installer said I could probably run a hotel off it.
 
By the way, Marge, the check is in the mail.
Pity.  I divided a gallon size plant with 6 crowns showing, and they all
are doing fine, so far.
