Pollution dropped, outside litter reduces, plastic bag reduction etc.

Best chances, sell drugs, or plastic surgery and find a good sugardaddy/sugarmommy.

Run out to Bed Bath & Beyond and get a bathroom trash can that a plastic liner fits in with a nice fitting lid.

That doesn't mean it's always a train wreck; I've had tenants build nice brick patios and do other stuff like that, and hey great if it increases the property value or decreases your cost, but I would be real careful with that.

My tenant spilled latex paint on the patio...and something else that looks like rust.  

Just liability coverage.However, weigh the risk with your tenants, I'd consider mowing along the stream, perhaps putting in a small patio nearby, sounds like it might be an attractive spot to sit.

I put in a row of evergreens and then put down plastic and covered it with stones.

We sometimes even provide moving boxes, tape, markers, and 3-mil thick large plastic bags for tenants to contain their belongings and move them efficiently.

I could see the damage this was beginning to cause, so we discussed it with the tenants, and agreed on a solution, which was they did not have to take it down, we scheduled a day to return, and wrapped/attached a single piece of thick soft plastic around the rack so that splashed water just runs back into the sink.
