Rain rain go away

We've had so much rain lately that - when it stops and dries up - we barely have time to mow the lawn before it starts raining again. This photo shows the base of the maple tree in our yard, with a number of ferns at the base of it.

At the lower right of the photo, you can see part of the troublesome retaining wall that is collapsing and posing a danger.

This shows a larger view of the area.

This photo shows where the very large shrubs were that we cut down last fall. I say shrubs even though they were more like trees because they were supposed to be shrubs but the previous owners didn't keep them trimmed so they became overgrown.

Both darkness and rain make the worms come out - it was both dark and rainy when I spotted this big worm when I let the dogs out to do their business just before bed. I figure it was well over 5 inches long.
