Neighbors Causing Foundation Issues And Now Want To Excavate A Pool

My parent’s neighbors moved in a few years ago and their land is a bit lower, so there is a short and steep slope down to their property and it’s an area with erosion. They have pulled up all the plants that the previous neighbor planted on the slope to control erosion and and we suspect that it has caused or at least exacerbated a bunch of recent foundation issues on my parents side, where it appears that my parents’ house and land is sliding down. The shared fence is basically now diagonal leaning towards their side and they refuse the fix it. (Edit: they have also removed part of the retaining wall)
They have now sent my parents a notice to excavate (addressed to my brother, who doesn’t even live there) to excavate and build a large pool.
What legal recourse do my parents have to oppose this before this worsens the foundation issues/land sliding? Is there someone at the county or city we can contact?
