Well, the lands still there, yes. Except for all the houses, driveways, swimming pools, streets and parking lots.
There are still a few ‘heirloom’ farms that get special tax dispensation on property taxes. The garden state is now the homeowners association state.
I’m thinking that with soil additions and reworking, lawns could become healthy, productive veggie gardens again. The soil additions are necessary because the builders brought a lot of subsoil to the surface digging basements.
