Las Vegas weighs tying growth to conservation amid drought

Cities in the U.S. West are preparing for considerable growth in the coming decades despite a historic drought and shrinking water supplies

CARSON CITY, Nev. -- Record-breaking heat and historic drought in the U.S. West are doing little to discourage cities from planning to welcome millions of new residents in the decades ahead. From Phoenix to Boise, officials are preparing for a future both with more people and less water, seeking to balance growth and conservation. Development is constrained by the fact that 46% of the 11-state Western region is federal land, managed by agencies like the U.S. Forest Service and Bureau of Land Management that are tasked with maintaining it for future generations. That's led officials in states like Nevada and Utah to lobby the federal government to approve land transfers to allow developers to build homes and businesses on what had been public land. Supporters in the two states have won over environmentalists in the past with provisions that allocate proceeds to conservation projects, preserve other federal lands and prevent road construction, logging or energy exploration. A small group of opponents is arguing that routinely approving these kinds of “swaps” to facilitate growth isn't sustainable, particularly in areas that rely on a shrinking water supply.
