@ retired engineer. Also, if you are going to have a "foundation" watering system's get rid of any gutters not above walkways. Gutters kinda defeat the purpose. I could go on a long rant about not having gutters in our climate.
@DanStanton: I would be interested in hearing the argument against gutters. I am on a corner lot, all clay even 6 feet under ground level. Is your profession in construction, structural engineering or the like?
