Ground gutters

The last few days, I have been digging holes. First, along the porch where there is no gutter, water runoff from the roof has been cutting arroyos into the lawn area on the east side of the porch. Solution? I dug a drainage ditch so that runoff from the roof will strike a gravel trench with a large plastic pipe which I opened up at grade, then perforated with a drill as it went further under ground. Then, with Lloyd's advice on the proper angle, I run the water north to the drive where it meets the upper cut in the driveway, carrying the water over the east side of the drive.

In this way, I can bring around 15% of the water runoff to a different place than the other areas of the house, putting less stress on the swale we built on the south border. But boy does it hurt, the day after.
