I posted this question yesterday and has since been marked as off topic, yet I fail to see why. It's about a garden/landscaping related issue that seems perfect for this SE. The issue of "urine smell" is secondary to the actual question being asked, as it's primarily about a drainage problem (as in, the same thing happens with rain water). I included this in case anyone had any suggestions for products or methods to use to help resolve situations where pet urine smells exist in the garden.
If this question is deemed as off-topic for this SE, can someone please point me to an SE where it's 100% on-topic?
Also, the linked meta question to explain the reason WHY it's off-topic actually suggests that "pest control" in the context of landscaping is on topic. While this is not about pest control in any way shape or form, the link is 100% unhelpful in explaining the reasons why kevinsky decided it was off topic.
