Drainage under path
The below photo shows a semi-completed path that will eventually be filled with med sized river stones.
However, as the photo shows, at one end (it runs downhill) it fills up like a pool when it rains so I'm hesitant to put the river stones in yet.
This is a path so will have foot traffic i.e. the soil will compact. I'm consdiering digging a large hole at the pooling end, and filling it with stones, to make a small soak pit. Any reasons not to do this?
