Those blocks were individually cut in to match the surrounding pattern, it was 100% done correctly. Those are recessed lids specifically for this, so you can hide manhole covers in block paving. Somebody definitely switched the lids later on. I’d guess the grass is where a block got dislodged and the hole filled with dust. Probably wasn’t a terrible job initially.
It looks like something you could lift up, like a sewer cover or something. Some madlad probably swapped them.
It’s an access panel. Some of them require a special tool and some require a type of key. Not sure on this one
Are they four individual panels? Because you could swap the second and theirs panels and you’d be pretty close.
Maybe this was originally correct and someone doing work later fucked it up. Probably on purpose.
