About 15 years ago, I was out in Phoenix and a local was telling me about the unlimited supply of water available from regional aquifers. I had been questioning how the city could maintain all its vernal golf courses in the middle of cactus filled deserts, let alone the rampant suburban development stretching to the horizons.
Arid landscapes had not been standing in the way of builders in Texas, Colorado, New Mexico, Utah, Nevada or Southern California either. Cheap land, warm climes, and new houses were a perfect combination for attracting snowbirds and other folks priced out of cold, more expensive and/or poorly ageing neighborhoods in the Northeast and Midwest. Summer heat could easily be offset by air conditioning. In fact, many of the fastest growing cities and counties in the country had been situated in virtual deserts or near deserts. I say had been, because now water or the lack of it will constrain these areas' development prospects and significantly increase local cost of living.
Arizona's “unlimited” aquifers are rapidly being drained and depleted Rocky Mountain snow packs reduce flows into the Colorado River threatening water supplies for communities from western Colorado to the Los Angeles area. I was out in New Mexico last month where a nearly 20-year drought has caught everyone's attention—a welcome near record late season storm dropped about 10 inches of light-airy snow near Santa Fe, but the cover of white rapidly evaporated in less than a day.
California, meanwhile, may be about to enter a freak-out, crisis mode after another dry “rainy” winter season—several quick hitting January storms, resulted mostly in run off and mud slides. More recently temperatures have registered well-above normal, auguring increased distress as reservoirs sink to dangerously low levels with another likely hot, rainless summer approaching.
At the very least, water rates will escalate in these places—an increasingly precious commodity will bear a high cost and add to living expenses. Battles between agricultural interests and population centers will intensify in California and Arizona—the nation's vegetable and fruit prices could soar, as more farmers get priced out. In extreme cases, builders will be unable to develop and some communities even may run out of water supplies. California may build desalinization plants to access ocean water—but the process is extremely power intensive (by the way power companies use a ton of water to make electricity) and has environmental costs. In Phoenix, Las Vegas and other Southwest locations, re-circulating grey water for industrial uses and watering the remaining golf courses will become absolutely necessary. Forget about lawns there and welcome to rock gardens. Having expansive lots will be increasingly less enticing without plantings and shade from trees and bushes, unless scrub brush is your thing. More restrictions and building codes will be put in place to reduce water use in homes and businesses, and make development more expensive and less enticing.
The population push into warm and dry zones, so dramatic over the past generation, may not come to an abrupt halt, but could slow dramatically. There is a reason when you fly cross country west of the Rocky Mountains why you see so much empty, inhospitable space—it's water, lack of it.
