ditch from hell, need help on how to fix my problem
 
Two months ago I decided to reconfigure my ditch. Yesterday we received about 3" of rain in 1.5 hours and this morning, I noticed the ground sinking pretty bad where I had backfilled the ditch. What can I do to fix the problem? I used river sand as backfill, and it was compacted and flooded before planting the sod. The sod had been growing for about 4 weeks now. I used an earthen fabric that goes along the bottom of the ditch and wraps up just past the seam of the 2x8 and 2x10.

I think I am going to dig up 18-24" of soil behind the lumber, and re-fill with 57 limestone, then fabric, then sand/soil. Since the height of the walls are only 18", I don't think I need install the 4" perf. drain pipes, do you?

Ayuh,.... I'd have used Dirt, not sand to fill,.... Dirt will shed water across it... sand allows it to soak in...
