one of my HOA’s had a large playground that was fenced in. We met the legal requirements to provide “access” to the playground for wheelchairs. Where access ended...because the required surface around play equipment is a soft plastic mulch material not able to support wheels. Best intents meets reality.
You can also used poured in place rubber for paths around equipment, at least in Indiana. Our local school has upgraded a few elementary playgrounds with that and our city has an inclusive accessible park that uses it as a play surface.
