Arizona Restricts Home Construction Amid Lack Of Groundwater
Pressures on water supply around Arizona, along with an ongoing megadrought made worse by climate change, have been addressed by recent limits placed on the construction of new homes around Phoenix. The restrictions are meant to limit projects that would rely on groundwater, as the groundwater supply is already needed by existing properties.
Most of Arizona’s water, around 41%, comes from groundwater, according to the Arizona Department of Water Resources. Another 36% comes from the Colorado River, although the state, along with California and Nevada, recently agreed to reduce their water intake from the river by 3 million acre-feet through 2026 as the Colorado River faces shortages.
