I don't know anything about building codes, but sticking a pipe out of a Kettering window to continuously drain water seems like it would violate a few. The water is slowly digging its own version of the Grand Canyon down the hill.
But when it gets to the street is where the truly amazing part starts. From the top of E. Sheilds St to the first storm drain the water has frozen, built up and over flowed the curb and is working its way to the sidewalk.
Can't believe the person did this never thought "wow, maybe this isn't too cool?"
