Not very practical in places like Florida and South Louisiana, where the water table is 6-12” below ground surface. And actually, not that much of a problem if the rights of way are KEPT CLEAR OF TREES.
I grew up in a “so small as to be virtually nonexistent” town in S. Louisiana. Electric power by a small REA. They were death on trees along the rights of way, and we rarely lost power....even in hurricanes, and then not for very long.
same here with the snow. they cut everything near any kind of power or phone/internet lines
