I assume original developers will have cashed out by then, someone else is left holding the bag, and the Salton Sea collapse story plays out a second time because it's just too expensive to maintain. That, or it's an exclusive enclave to the LA ultra-wealthy who don't mind that the high taxes keep the undesirables away, all while they've gotten the state to subsidize their vacation homes because the state is trapped and can't afford not to keep the machine running.
