My first take is that this is a pretty good location- you're not going to spend an hour looking behind bushes for it, there won't be an a/c set in front of it, you're not standing in the mud, a mile from your truck, etc.
The small trash can can be easily moved, and will serve as a "warning" to a careless
parker. The installation of more substantial barriers has often been cited as a working space violation- even though code requires protection from traffic hazards!
