Above the structure is a pretty thick forest and only about another 100' elevation increase over a mile or so.
So zero threat of a flood, and highly unlikely mud slide.
Hopefully!!!

Make sure you put a drain pipe to collect water including gravel around the foundation to remove any ground water that builds up.
