Hey- I'm a homeowner in central ohio and was digging some drainage trenches to install french drains and get water from my back yard into a front ditch. About 30 feet from the street and 40-50 feet from my house, along a treeline, I was only about 8-12 deep when I hit something hard. I've been fighting with tree roots and rocks, but was surprised as I continued to excavate the object when I realized that it was a cinder block. Does anyone have any idea why I would encounter a cinder block in my yard? I stopped right where I was, not knowing what it was (or was part of) I didn't want to damage it. I'm told that our neighborhood was farmland in the 70's and that there's a lot of old farm drainage (neighbors call them "tiles") underground....but I don't know why a cinderblock would be used for drainage...retention maybe...but not drainage. But, this is my first drainage project, so I appreciate assistance. Does anyone have any thoughts on what I've encountered and whether its safe to dig this block out and continue with my french drain installation? I appreciate any advice! Thanks Ryan
