If there is enough drainage wouldn't it be ok to leave it in place and rinse it with hose (or rain)?Almost everyone who has tried a variety of things in runs says that washed river sand is the way to go. I think it's important to prepare the base correctly from the beginning. I'd take out several inches of dirt, put a thick premium landscape fabric down, pack crushed rock down first. Then add boards around and fill about 4 more inches of washed river sand. It still must be maintained and people remove it every 6 months. I've seen several people say they leave it in a pile to be washed by rain and put it back in 6 mos later, when they remove what's in the run.
