Wind + Torrential Rain + Dead Ash Trees

Walking around the forest, I found one of the continuing impacts of the emerald ash borers that came through Michigan a few years ago, destroying all the planted ash trees throughout the area (including Saginaw Forest).

In addition to the expected ecological changes that are caused by the loss of a significant tree species in a forested area, there are direct physical impacts that are likely to happen, such as winds toppling the trees in the sodden ground caused by recent torrential rains (~1.7 inches in 2 hours). In this case, the toppled tree's roots pulled up parts of the road next to it...

I wonder how I'm going to apply maintenance to this problem:
