Adding sand to my lawn
Hello, I have about 2500 sq ft of lawn. My home is in the Damascus area on one of the volcanic buttes here. The lawn is growing on sloping clayey ground with the top 4-6 inches composed of a soil mixture that I've added as a top dressing over the last 5 years. In the last two years this soil layer has become very water saturated during the winter and spring. I've dug a few post holes to look at the soil profile and it's clear that this soggy-ness is confined to that soil layer and is most evident in those areas that receive the most run-off from paved areas. I've been advised that adding clean (washed) sand to the soil layer will improve drainage and add some structure to the soil that is currently missing. Does that sound like a reasonable approach to mitigating this problem?

I would not recommend sand instead I would tell you to add organic matter.
this will build tilth and a better soil
