water is a hardscape's enemy. Whether it's a patio or a wall. You do not want any water near the hardscape. So if it means trenching and piping 40' of pipe - then thats what you gotta do. The objective is to get the water away. I find we can usually accomplish this in under 20'. We usually daylight the pipe. But sometimes we have had to install drywells.
