It isn't so much the population boom as it is the uncontrolled building. Local governments are allowing new building without studying what additional infrastucture is needed. Water, roads, utilities, etc. are considered after the fact rather than before. Folks like me, who have lived here nearly our whole lives, have watched as one thing after another is reduced. We're down to watering our grass to once a week, while newly constructed areas can be watered whenever, for, I believe, up to 4 months.
Now, I'm not against growth or new construction, but we should put the horse before the cart rather than the other way around.
What we are starting to see is the result of decades of liberal environmental policy coming home to roost.
No new dams + no new highways + no new power plants + unbridled immigration -> a big mess.
