Any way to modify the small, ugly parks that aren't on the map?

There are several of these awful little parks in the game that have no way to access them, and they're useless as is. Can't even place a chess table, for crying out loud! I know because I tried. I used TOOL but the table moved (and sunk below ground level) and the chairs didn't stay attached. So we're stuck with truly awful lots taking up valuable space and no ability to make them "pretty" or fill them with actual and useful items, like chess tables, swingsets...even standard decorations.

But if someone knows how to do this, please let me know. They really bug the heck out of me.

Maybe this should go on a wishlist for EA...except it would probably only apply to the world/save created after an update.
