Arizona's state water supply loophole is causing a gold rush for multifamily construction

2023-11-14T12:31:00-05:00

Local leaders near Phoenix are placing limits on where new homes can be built, with the goal of protecting long-term access to water. But there's a significant loophole. [...] Policymakers may try again, and the governor has set up a task force on the issue. Ferris says the strength of Arizona's water law is that it links building decisions with water decisions. No other Western state requires cities to look a hundred years into the future.

Permitting of new subdivision construction has been curtailed in the Phoenix area over water scarcity, though a loophole over multifamily construction has led to a recent boom there as developers are still free to open state taps when needed in search of a requisite 100-year groundwater supply.

Small cities like Casa Grande and Buckeye are making the news as prolific cases, with around 3,000 and 6,500 new units permitted in each in the last two years alone. The official statewide need stands at 200,000 overall. Lawmakers are now trying to put a halt to the build-to-rent exemption in the face of a population influx and despite developer’s lobbying.

Arizona to limit construction in the Phoenix area as groundwater supply shrinks

2023-06-03T09:17:00-04:00

Arizona has determined that there is not enough groundwater for all of the 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.

This decision, announced last Thursday, means that Arizona will no longer provide developers in some areas of the Phoenix region new permits to construct homes that rely on groundwater. Maricopa County, which includes Phoenix, sources half of its water supply from groundwater. The announcement will not impact developments that have already been approved. However, the state will be looking towards new water conservation measures and alternative sources to provide the water needed for these projects. The decision will likely have a significant effect on Arizona’s real estate market, especially in Phoenix, which has become the fastest growing metropolitan region in the country, due to the impact on housing affordability.

Now, developers looking to build will have to prove that they can ensure water supply for 100 years using water from a source that is not local groundwater. This move is another example of how the impacts of climate change continue to grow in prominence. In addition t...

Huge groundwater reserves discovered deep below California's Central Valley

2016-06-28T13:49:00-04:00

In a surprising new study, Stanford researchers have found that drought-ravaged California is sitting on top of a vast and previously unrecognized water resource, in the form of deep groundwater, residing at depths between 1,000 and nearly 10,000 feet below the surface of the state’s always thirsty Central Valley. [...] new research could prove controversial among scientists trying to interpret what it means for a state that has battled over water, and its distribution, going back many decades.

Scientists create first detailed map of Earth's hidden groundwater

2015-11-24T12:07:00-05:00

A new study has, for the first time, estimated the total volume of groundwater present on the Earth. The results show that we're using up the water supply quicker than it can be naturally replaced, while future research will seek to determine exactly how long it will be until modern groundwater runs dry. Groundwater is an extremely precious resource, being a key source of sustenance for humanity and the ecosystems we inhabit.

Chinese Cities Are Sinking Due to Excess Groundwater Use and Rapid Growth

2012-04-03T19:35:00-04:00

New studies are showing that Chinese cities are slowly sinking as a result of rapid development and excess groundwater use. According to reports, as many as 50 cities across the country are affected by soil subsidence, including the country’s largest - Shanghai. Apparently, Shanghai has been slowly sinking for at least 90 years.
