Arizona limits building as groundwater dries up

LOS ANGELES: New houses that rely on dwindling groundwater supplies around one of the United States' biggest cities are to be banned, officials said Thursday, in a sign of the strains that drought and climate change are causing across the US west.

Water managers in Arizona say there is a significant shortfall in the Phoenix area, and that any more development in the fast-growing city must rely on other sources of water — such as under-strain rivers.
