Wow - nasty lightning storm last night. And I was out in the beginnings of it still working on the ditch. Had to lower the spot where the existing pipe exits, or the water would pool and actually flow backwards into the area I wanted to drain! After 10 min of frenzied digging, past rocks and gravel and landscaping fabric, I had a more or less even drop from the end of the pipe to the fence, and then a generally downward-trending slope along the fence. It looks like I need two more 10' sections of pipe to get the water to go properly and not flood the neighbor's side-yard. Nothing I can do with the backyard, however.
