Re: Downspouts are buried in the ground
This won't help you much but I thought you would enjoy our experience. When we moved in to our house we saw pvc (pcv? I can never remember which) going under the fence from our neighbor's yard ending in our yard. It seemed that a previous owner to their house buried their downspouts and had them drain into our yard! Problem solved! When we talked to the neighbors about it they happily changed it.
