My basement is getting wet, my side yard has a depression that's about 15 feet in diameter.

I've dug a trench that's about 2 feet deep and 2 feet wide. I'm going to put plastic down in the bottom, some gravel, perforated corrugated pipe, (and an unperforated pipe for the gutters, more gravel, landscaping fabric on top, than soil, running down hill, and out the hill in my front yard.

Does this look okay?

Any suggestions appreciated!!
