The effect of climate change is battering the west coast: Arizona Limits Construction Around Phoenix as Its Water Supply Dwindles

[Anerdyblackguy]

Arizona has determined that there is not enough groundwater for all of the future housing construction that has already been approved in the Phoenix area, and will stop developers from building some new subdivisions, a sign of looming trouble in the West and other places where overuse, drought and climate change are straining water supplies.

The decision by state officials marks the beginning of the end to the explosive development that has made the Phoenix metropolitan region the fastest growing in the country.

Maricopa County, which includes Phoenix and its suburbs, gets more than half its water supply from groundwater; most of the rest comes from rivers and aqueducts as well as recycled wastewater. In practical terms, groundwater is a finite resource; it can take thousands of years or longer to be replenished.

The announcement of a groundwater shortage — what the state calls “unmet demand” for water over the next hundred years — means Arizona would no longer give developers in areas of Maricopa County new permits to construct homes that rely on wells for water.

Phoenix and nearby large cities, which must obtain separate permission from state officials for their development plans every 10 to 15 years, would also be denied approval for any homes that rely on groundwater beyond what the state has already authorized.

The decision means cities and developers must look for alternative sources of water to support future development — for example, by trying to buy access to river water from farmers or Native American tribes, many of whom are facing their own shortages. That rush to buy water is likely to rattle the real estate market in Arizona, making homes more expensive and threatening the relatively low housing costs that had made the region a magnet for people from across the country.

“We see the horizon for the end of sprawl,” said Sarah Porter, director of the Kyl Center for Water Policy at Arizona State University.

The state says it would not revoke permits that have already been issued and is instead counting on water conservation measures and alternative sources to produce the water necessary for approved projects.

A groundwater shortage would likely not derail the planned growth in the short term in major cities like Phoenix, Scottsdale and Mesa, Ms. Porter said.

“There is still capacity for development within designated cities,” Ms. Porter said, referring to cities whose growth plans had already been approved by state water officials. Those cities would not be able to get approval to build anything beyond that amount.

The new restrictions would be felt hardest and most immediately in small towns and unincorporated swaths of desert along the fringes of the Phoenix metro area — where most lower-cost homes tend to get built. “Those have been hot spots for growth,” Ms. Porter said.

The announcement is the latest example of how climate change is reshaping the American Southwest. A historic 23-year drought and rising temperatures have lowered the level of the Colorado River, threatening the 40 million Americans in Arizona and six other states who rely on it — including residents of Phoenix, which gets water from the Colorado by aqueduct.

Rising temperatures have increased the rate of evaporation from the river, even as crops require more water to survive those higher temperatures. The water that Arizona receives from the Colorado River has already been cut significantly through a voluntary agreement among the seven states. Last month, Arizona agreed to conservation measures that would further reduce its supply.

The result is that Arizona’s water supply is being squeezed from both directions — disappearing ground water as well as the shrinking Colorado River.

And the water shortage could be more severe than the state’s analysis shows because it assumes that Arizona’s supply from the Colorado would remain constant over the next 100 years — something that is uncertain.

Arizona’s water problems have begun to percolate through the state’s politics. In January, the new governor, Katie Hobbs, a Democrat, pledged in her first major address to tighten controls on groundwater use around the state.

As evidence of that commitment, Ms. Hobbs released a report that she said had been suppressed by the previous Republican administration. It showed that an area west of Phoenix, called the Hassayampa sub-basin, doesn’t have enough water for new wells. As a result, the Arizona Department of Water Resources said it would no longer issue new permits in that region for home construction that relied on groundwater

But Hassayampa is just one of several sub-basins that make up the larger groundwater basin underneath metropolitan Phoenix. The state’s announcement on Thursday essentially extends that finding across the Phoenix area.

One of the places likely to feel the impact of the new restrictions is Queen Creek.

When Arizona created its groundwater rules more than 40 years ago, Queen Creek was still mostly peach and citrus groves and expansive farmland. Today, it is one of the fast-growing places in Arizona, where families go fishing at an “oasis” lake fed by recycled wastewater. The town’s population of 75,000 is projected to grow to 175,000 by the time it is built out decades from now.

But to do any of that, the town needs to find more water.

“We’re in search of about 30,000 acre feet” — or about 9.8 billion gallons, said Paul Gardner, Queen Creek’s utility director.

Since there isn’t enough groundwater to supply its needs for future growth, Queen Creek is hunting for water anywhere it can — exploring proposals such as transferring it via canal from western Arizona, expanding the Bartlett Lake reservoir by joining other cities in a project to build a higher dam.

Unlike Phoenix, Queen Creek doesn’t have what’s called a “designation” from the state — essentially, a determination that the city has enough water to support new homes. Without that designation, each proposed development must prove to the state it has a 100-year supply — and developers without that seal of approval would now have to find sources other than groundwater.

Even as the state takes steps to try to slow depletion, the Kyl Center has warned that Arizona is still pumping too much groundwater. New industrial projects are sucking up groundwater without restrictions, and demand for water is outpacing any gains from conservation efforts, the center found in a 2021 report.

Despite the increasingly dire warnings from the state and water experts, some developers are confident that construction will not stop anytime soon. The Arizona water agency has given permission for construction on about 80,000 housing lots that have yet to be built, a state official said.

Cynthia Campbell, Phoenix’s water-resources management adviser, said the city largely relies on river water, and groundwater represents only about 2 percent of its water supply. But that could change dramatically if Arizona is hit with drastic cuts in its Colorado River allotments, forcing the city to pump more groundwater.

Many outlying developments and towns in Maricopa County’s sprawl have been able to build by enrolling in a state-authorized program that lets subdivisions suck up groundwater in one place if they pump it back into the ground elsewhere in the basin.

Ms. Campbell said the idea that you could balance water supplies like that had always been a “legal fiction” — one that now appears to be unraveling, as the state takes a harder look at where the groundwater supplies are coming up short.
“This is the hydrologic disconnect coming home to roost,” Ms. Campbell said.
In outlying areas “a lot of the developers are really worried, they’re freaked,” Ms. Campbell said. “The reality is, it all came back to catch us.”

NA's really going to love to hear the White Man wanting their water. If you want to start, kill the Alfalfa Fields because they are using the unregulated water.

If your in Arizona, get ready to pay for Culligan or a Water Truck.

Those places should have had water regulated heavy in all use cases. No reason to be growing shyt like almonds and alfalfa in areas with comparatively low water access.

I'm worried the Great Lakes will be pillaged in the next 20 years as other areas also start to get worse.

most of the black and brown millennials and gen z i know that can afford a house in a "safe" neighborhood had to get it in places like queen creek. maricopa city is probably the only long term viable option for new expansion. either that or they might have to stick to developing more of south phoenix like laveen where my uncle is at. white people wont buy over there no matter what.

ironically, there are tons of urban fishing holes in the whole phoenix metro area now. i just got my first fly rod today. bout to go get some of those reclaimed wastewater fish

How many golf courses are in Arizona? I bet they are exempt from restrictions because rich men have to hit a golf ball.

 

[Gritsngravy]

Isn’t somebody (maybe bill gates) trying to build a city in Arizona ?

Is it worth it putting resources towards making sure Arizona has water, maybe Arizona isn’t meant to be a big state

 

[Gritsngravy]

Arizona fukk around and turn into a place only people with money live at, cause they probably going to tax people on this water shyt and who going to really afford that

great first step I guess


should apply to the entire south west, like straight up green glass the entire place

@the next guy

At least they have the constitution





Live in the south(west) brehs!!!
