This was an interesting read for me.<p>I have a cabin on some land near Joshua Tree. There's water in the ground (300-400ft down) but I haven't bothered to put in a well, instead just hauling what little I need from the nearby town's bulk water dispenser.<p>Unlike AZ apparently, CA doesn't allow any new construction without a secure and sufficient water supply. Installing new cisterns for receiving hauled water is no longer permitted, but existing cisterns are grandfathered in. It seems like they never make any exceptions. A nearby fire station permanently closed when their well water was found to be too toxic and they weren't permitted to install a cistern for hauled water.<p>It seems like AZ could solve this issue state-wide by adopting a similar permitting requirement, instead of having these parcels-of-5 loopholes enabling entire subdivisions to be built without water.<p>The problems my area has been dealing with are illegal agriculture (large marijuana grows) depleting the ground water, and there's always some hare-brained commercial plan trying to plow through the red-tape and resell the cheap but finite groundwater in one form or another.
