Palms and Cycads: Exposed palm roots OK?, 0 by Chiefengineer

This morning I woke up to find some tree trimming done.
Apparently my new pup went to work Christmas Night trimming
a mature Washingtonia Robusta next to my pool (see pic).

Unfortunately it is on a steep hillside and there to prevent erosion
among other things. After thinking: "OK, these things will need to
be trimmed someday anyway", I noticed the exposed roots on the
downhill side (see lower part of pic).

We are having one of the coldest, weirdest winters on record...like
20F below normal with lots of freezes. Perhaps one of you knows
if exposure of roots like this poses any risk to this tree (like freezing)...it
is next to a pool and concrete but on the opposite side.

If I have to I will build a retaining enclosure and fill it with dirt...but part
of the reason for already not doing this is the tree itself: It has grown
straight up and is very healthy. What do you think? Any/all suggestions
very welcomed!
