For those of you following the plight of my Midknight Valencia Orange … it too has become part of my renovation project.
So this morning a few guys came over with a 90-lb jackhammer and spade attachment. They dug a 1-foot diameter hole down another 30" or so below the 32" inch depth of the craters we dug last week. What they found was about 10" of semi-permeable caliche sands followed by an undetermined depth of thick dark muck characteristic of marine estuaries.
Since there is a steady downward gradient to the east, I’ve decided to install a French Drain from each of these 4 tree holes towards my retaining wall which has a gravel backing and drains leading to the property behind me about 5 feet below.
