Arizona officials announced Thursday the state will no longer grant certifications for new developments within the Phoenix area, as groundwater rapidly disappears amid years of water overuse and climate change-driven drought.
A new study showed that the groundwater supporting the Phoenix area likely can’t meet additional development demand in the coming century, officials said at a news conference. Gov. Katie Hobbs and the state’s top water officials outlined the results of the study looking at groundwater demand within the Phoenix metro area, which is regulated by a state law that tries to ensure Arizona’s housing developments, businesses and farms are not using more groundwater than is being replaced.
The study found that around 4% of the area’s demand for groundwater, close to 4.9 million acre-feet, cannot be met over the next 100 years under current conditions – a huge shortage that will have significant implications for housing developments in the coming years in the booming Phoenix metro area, which has led the nation in population growth.
State officials said the announcement wouldn’t impact developments that have already been approved. However, developers that are seeking to build new construction will have to demonstrate they can provide an “assured water supply” for 100 years using water from a source that is not local groundwater.
