Raccoons and possums live a lazy urban life nowadays. We had a mama and her three babies come visit and when I spooked them (they are nocturnal) the babes headed up my pine tree just a few feet from where I was standing. Momma stayed just on the other side of the cyclone fence giving me that look that said I better get back in the house or else. They do poop all over the lawn and the possums seem to keep it along the foundation of the house. It is all rather stinky in the summer. The raccoons are attracted to my goldfish pond. I used to have koi but they were so friendly they would come to edge regardless of what they saw at the edge. So I don't have koi any more, just goldfish. They are smarter, I think.
Looks like you have a good supply of sedums to work with
