I’m my opinion this situation is different since he had permission and his agreement states it runs with the land. This lock him to have permission forever. He shouldn’t be bullied around when he is on the right side of the law. City officials think they can do whatever they want but this guy has contract law on his side. They can’t touch him and if they try he should file suits early and often. Mater of fact he should file before the city knows what hit them. Offense is the best defense in situations like this.
