I have a water issue in our backyard that can mostly be solved by our neighbor handling it properly. But even if they do, I expect a large storm to put us in the current situation.
The consequence of the water is a small river that flows across our property and down our driveway. The water doesn't flood any area, it actually is pretty well behaved.
We would like to use this space for a patio though and thought we could handle this two different ways,
1/ build the patio to allow the water to flow over it.
2/ capture the water (patch of crushed stone) and pipe it under and out the driveway.
I claim erosion will cause long-term problems to the former resolution but the later could be complicated and expensive (building the patio twice would be more expensive though).
Is there any precedent for handling water by letting it flow over a patio like this? It seems most contractors are happy to over-engineer a water capture system, but I haven't been able to find anything else. Thanks for any advice.
