I don't know--I haven't seen them yet. The accessible campsites I've seen are concrete pads with a picnic bench, and a sidewalk from the parking area to the pad. The parking is also paved or concrete. The nearby bathroom is also accessible.
2 feet high? lol--that would make it a challenge wouldn't it

. Kind of adds the element of challenge to camping I guess. Hopefully, they will backfill the pad around it so it's just a few inches high.
