Have read with interest your plight, and have had the same experience.
Seems the raccoon will dump on a spot, and it will attract others to do the same thing, as well as the original coon will come back to that spot. What I do, when I find it on my deck, is wash it down with the hose, then spray with a solution of bleach. Seems the bleach will cover the odor of the scat and discourage them from returning to this area as a 'toilet' dumping spot. Ihad a lot of firewood stored in an open shed, and for years had the problem of the surrounding coon using it as a 'dumping' ground. There was a layer a few inches thick from the visits, that could not have been just one coon. After thinning them out, they still used it but not as much. I now store all wood on pallets outside, and have enclosed the shed. No more coon in there!
As to trapping, I live trap them. 3 and 4 years ago, I trapped 36 one year and 38 the next. This has been discussed in another thread. I 'imprint' them before they leave the trap, so I know the same one doesn't get back in there another time. If I had a spot, I too would just lower the trap in water and drown them (I think this is the cleanest way to go, as they blank out and there is no mess). Sorry Danny.
This year I am back at trapping. Find that marshmallows work pretty good in the live trap. Part of my problem is the nice folks who trap them in town and then dump them off 'out in the country' to give the problem to someone else. Having trouble now with too many squirrels, and find a neighbor who lives in town has been doing just that. Braggin' about how many squirrels he has live trapped in town. I have gotten pretty deadly with the .410 double barrel, and have the population thinned down a bit.
I am concerned about the disease that the coon carry, which can become airborne from the dried scat. Whatever it is, it stays viable for a long time, and am concerned for children that visit and just touch everything and don't wash before putting their hands in their mouth. It is a disease that is particularly rough on children. I need to locate the source of the information I have somewhere.
P.S. I don't put out any food for any animal or bird.
