Before I could react my oldest went to get off the slide and his foot accidentally hit my 5 year old's hand and over the side of the slide he went, landing flat on his back in the rocks from about 4 feet up. Luckily he was okay, no broken bones or serious injury, just some scratches and bruises...but did you catch that little bit about the rocks? Yes, under our playset is rocks, not exactly ideal. So what's the story with the rocks you might ask?
A natural spring.
Eventually we had to bring in professionals who installed two french drains from the natural spring to the back of the yard where it drains into the wetlands behind our property. It helps for the most part, as you can see in these pictures after a heavy rain there is still standing water for a bit, but it left the area underneath our playset covered in rocks over the drain locations. The waterlogged dirt has also made grass growth spotty at best.
