Let's think this through:
Tesla cannot get a zoning change without getting a lease agreement. If Tesla gets a lease agreement first and then doesn't get the zoning change, they have to break the lease.
On the other hand, if the owners get a zoning change and Tesla backs out of the agreement (ie: because they can't get enough electrical power to the location safely and inexpensively), the owners lose out by having zoning changed potentially to something they can't exploit the land for later.
Only way this works is if Tesla signs a lease agreement with a 90-day out clause and hopes for the best.
