Attorneys with the Goldwater Institute are scheduled to appear in Maricopa County Superior Court at 10 a.m. Friday for a hearing in their lawsuit challenging water policy changes implemented by the administration of Katie Hobbs.
The case, filed in January 2025 on behalf of the Home Builders Association of Central Arizona, contests new requirements adopted by the Arizona Department of Water Resources (ADWR) affecting groundwater supply determinations in parts of Maricopa County.
The Goldwater Institute said the policy changes have halted approvals for new housing developments in certain areas of the Phoenix metropolitan region, including portions of Queen Creek and Buckeye.
Under Arizona law, homebuilders in designated Active Management Areas must obtain a certificate demonstrating a 100-year assured water supply before beginning construction.
Goldwater’s lawsuit challenges a policy change announced by ADWR in November 2024. It contends that the department adopted a new framework based on what it describes as “unmet demand,” which it says is not referenced in Arizona statute.
Goldwater penned a letter to the ADWR one month later, urging the agency to reconsider its “AMA Wide Unmet Demand Rule,” asserting that the new rule was in violation of the law, having been imposed without legislative approval or via the required rulemaking process.
ADWR has defended its authority to interpret and apply groundwater modeling within the state’s assured water supply program. The department has not publicly characterized the policy as a formal rulemaking.
The Maricopa County Superior Court previously denied ADWR’s motion to dismiss the case, allowing the lawsuit to proceed.
During Friday’s hearing, attorneys for Goldwater are expected to ask Judge Scott Blaney to enter judgment in favor of the Home Builders Association of Central Arizona.
The case is being heard at the Maricopa County Superior Court, East Building, located at 101 W. Jefferson Street in Phoenix.
In a statement, Goldwater Institute Vice President for Litigation Jon Riches said: “Decisions on vital statewide concerns like the availability of affordable housing and the responsible stewardship of our natural resources should be made through a transparent, democratic process—not imposed by executive fiat.”
Additional information about the case is available on the Goldwater Institute’s website. No ruling is expected at the time of the hearing.

From harvesting timber in national forests to grazing cattle on the open range, our nation has faced many tragedies of the commons over the years. Whether hunting big game in the wild or extracting oil and gas from underground reservoirs, each example presented our leaders with the same, fundamental issue: if nobody owns it, everyone will overuse it.
For rural Arizona, groundwater is no different. As explained in Part 2, Arizona’s groundwater challenges are a tragedy of the commons, stemming from the fact that groundwater is a finite resource with multiple landowners on the surface, any one of whom can tap into the common supply.
How we approach this tragedy moving forward will determine not only the health of the aquifers but also the future of our rural communities. While some proposals have been offered to date, none have been sufficient to earn legislative support, and most have been wrong for our state.
To get it right, we must consider the approaches that have been taken in other contexts to see which have worked and which have not, allowing us to determine which could be the best fit for groundwater.
There are generally two approaches
According to Dr. Stephen Hicks—professor at Rockford University, critic of socialism, and supporter of individual rights—every solution for the tragedy of the commons falls into one of two categories: a socialist approach and a property-based approach.
The socialist approach views self-interest as the problem. It seeks to control human behavior through mandates, permits, and fees. Whether renewable energy standards for climate, catch limits for fisheries, or sustained yield mandates for national forests, all prioritize resource preservation through government control—maintaining communal ownership and regulating beneficial use through bureaucrats who decide who can use what, when, and how much.
The property-based approach, on the other hand, views communal ownership as the problem. It seeks to eliminate the tragedy by establishing private property rights to the resource, allocating individual shares and allowing users to manage and conserve their own supplies, limited only by the fundamental principles of private property rights, such as the “no harm” principle and “right to exclude.”
Mining claims have operated on “first in time, first in right,” and grazing allotments grant exclusive rights to leaseholders, thereby reducing conflicts among users and making individuals responsible for their own supplies.
To address rural groundwater, Arizona leaders must decide which of these approaches they will take.
Socialist options don’t work
Quod nullius est, est domini regis. It means: “What is the property of no one, belongs to the king.”
In 1976, after the Arizona Supreme Court declared groundwater a public resource, the Court said: “The legislature has the authority to determine which groundwater uses are most important to the general welfare and to allocate the state’s groundwater resources accordingly.”
This statement illustrates the truth about communal ownership: if no one owns the resource, then the government has absolute authority to act as king over its use. This is why the Arizona Department of Water Resources frequently reminds landowners that their right to use water is only “usufruct” to the land they own: meaning they don’t own the groundwater itself, the state does.
Like wild animals in Old England, communal resources belonged to the Crown—hunters could only hunt when, where, and how the king said they could. Those systems, like today’s socialist groundwater regimes, treat resources as communal property controlled by government fiat.
Such approaches typically fail because they lead to higher scarcity, higher prices, and worse outcomes for the resource itself. The federal government’s centralized control over national forests, for example, has produced catastrophic wildfires, endangered protected species, and restricted affordable timber.
In Arizona, the infamous “management area” is the hallmark socialist approach to groundwater— including 1948 “Critical Management Areas” and 1980 “Active Management Areas.”
According to Dean E. Peterson and Larry L. Deason in Arizona’s Groundwater Problem & Proposed Legislation, the 1948 Critical Management Areas “did not adopt any of the basic principles of water law,” but rather were an “exercise of the general police power of the state” through centralized restrictions.
In 1980, Arizona doubled down on its socialist approach with the Groundwater Management Act, establishing “Active Management Areas” that centralized control into the Arizona Department of Water Resources. This gave the agency near-absolute power over groundwater in AMAs, allowing its director to effectively act as king over the common supply.
In both cases, users rushed to drill before grandfathering deadlines, and corporate and municipal users entrenched their historical pumping, distorting market incentives. After 40 years, the 1980 Act has failed to achieve “safe yield” in most AMAs.
Despite their clear failures, proponents today continue to argue that Arizona should “finish what was started” with the 1948 and 1980 groundwater acts by expanding socialist-style control statewide through “Rural Groundwater Management Areas” and “Local Groundwater Stewardship Areas.”
These proposals must be rejected, as they would only impose new bureaucracies, tax personal groundwater withdrawals, and mandate volumetric reductions while maintaining the same communal ownership model that led to the tragedy in the first place.
Property-based solutions are best
Meum et tuum. It means: “What’s mine is mine, and what’s yours is yours.”
According to John Locke in his Second Treatise on Government, the role of government is not to seek to control human behavior, but rather to protect private property by using the limited power of government to quantify and secure individual rights, prevent takings, support transferability, and uphold the “no harm” principle and biblical golden rule between and among property owners.
Rather than mandating conservation through coercion, property-based systems embrace human nature and seek to harness the power of self-interest to guide the invisible hand toward voluntary conservation.
History has proven that this approach works. When socialist mandates in American fisheries led to overfishing, policymakers switched to property-based catch shares and individual transferable quotas, which restored fish populations.
When hunters arrived in the New World, they rejected the Old English system and adopted the North American Model of Wildlife Conservation, which includes transferable hunting permits, helping to maintain healthy wildlife populations while providing a fair system of access.
Even “adopt a highway” programs harness self-interest to address trash and litter on public highways, granting exclusive naming and advertising rights to private parties in exchange for maintenance.
Overall, individual ownership protects scarce resources better than bureaucratic control because direct ownership creases individual responsibility. Where individuals are given ownership and responsibility, conservation increases because what belongs to someone is protected by someone.
Arizona needs correlative rights
To solve Arizona’s groundwater tragedy, we must remove it from communal ownership and apply a property-based approach. One solution designed specifically for finite underground resources like groundwater is “correlative rights.”
Derived from oil and gas law in resource-rich states like Texas, Oklahoma, and Nebraska, correlative rights allocate proportional shares of the resource to adjoining landowners on the surface, based on the amount of land they own. If a person owns five percent of the surface, then they own five percent of the oil and gas below, plain and simple. This is consistent with the ad coelum doctrine described in Part 1.
In many of these resource-rich states, policymakers have already adopted correlative rights for groundwater. In Texas, for example, the Edwards Aquifer Authority uses correlative rights to allocate groundwater. In Nebraska, natural resource districts administer correlative rights.
Because allocations are treated as real property, users are free to trade their shares among themselves within the same basin—allowing market forces, rather than government bureaucracy, to dictate the most efficient use of limited resources.
This is why correlative rights have been such an effective way to prevent the tragedy of the commons in finite underground resources to date. As a proven, property-based framework rooted in America’s traditional values, correlative rights are the right approach for Arizona.
It’s time to restore private property rights to groundwater
When the Arizona Supreme Court enshrined “communal ownership” into law, it likened groundwater to a wild animal, saying it was “free to roam as [it] please[d]” and the “property of no one” until “captured.”
In so doing, it wrongfully embraced the Old English model that Americans rejected and failed to follow the American path that utilizes private property rights to advance the public good. This must be undone.
To address the tragedy of the commons in Arizona, we must recognize the harms of communal ownership and reject the socialist schemes that seek to maintain it. Only by restoring private property rights to groundwater through the adoption of correlative rights can Arizona finally address the tragedy and allow landowners to protect and conserve the supplies beneath their feet.
It’s time that Arizona leaders consider a new approach to groundwater supplies. As Arizona Justice Duke Cameron wrote in 1976: “The time has come to consider again the doctrine of correlative rights.”

The Goldwater Institute recently sent an email that its lawsuit announced in January against the Hobbs administration is moving forward.
In the email, Goldwater highlighted the potential impact of the Arizona Department of Water Resources (ADWR) controversial new rule imposing the requirement of a 100-year groundwater supply across wide swaths of the state.
Goldwater’s Vice President for Litigation Jon Riches wrote, “This government overreach sets a troubling precedent for other bureaucratic agencies to bypass the authority of the legislature. Due to ADWR disregarding the legislative process and the risks posed by the water rule, the Goldwater Institute is suing Governor Hobbs’ administration.”
Goldwater is challenging the Arizona Department of Water Resources’ (ADWR) controversial new rule imposing the requirement of a 100-year groundwater supply across wide swaths of the state. The troubling regulation was detailed earlier this year in an op-ed from Goldwater’s Vice President for Litigation Jon Riches and in a report by AZ Free News.
Riches explained that Hobbs’ appointed Director of ADWR, Tom Buschatzke, is “working outside Arizona law,” by implementing the new “unmet demand” rule, unilaterally without legislative approval or following the statutory rule-making process.
He wrote, “Despite Buschatzke’s apparent desire to act as a mini czar with unilateral power to determine this state’s water policy, his authority — like all government power — is constrained by Arizona law. And that law is crystal clear: When regulatory agencies like ADWR attempt to impose sweeping policies — such as halting all new home construction across large parts of the Valley — they must do so through formal rulemaking, allowing for public input. Instead, Buschatzke sidestepped this requirement and imposed his homebuilding moratorium with the stroke of a pen. The Goldwater Institute, where I work, is now suing the agency to halt the illegal rule.”
In the email, Riches warned, “If someone wanted to build a house, they would be blocked from doing so if another part of the designated region, miles and miles away, did not meet the criteria of this water rule.”
The email also outlined three direct impacts that Arizona taxpayers could expect to feel: “Increased housing costs, prevention of homebuilding, [and] a dangerous precedent for government overreach.”
Riches added, “This is one of the most critical lawsuits by the Goldwater Institute in our history. We have been successful in challenging unconstitutional laws in the past, and we are ready to fight this one.”
The complaint in Home Builders Association of Central Arizona v. Arizona Department of Water Resources can be found online here. The case is currently in the Maricopa County Superior Court pending a response from the ADWR.

Arizona’s ongoing housing crisis is taking center stage as state lawmakers, led by House Majority Leader Michael Carbone, voice strong opposition to Governor Katie Hobbs’ water policies, accusing them of exacerbating the state’s housing shortage. In a statement released last week, Carbone applauded House Speaker Steve Montenegro for authorizing a lawsuit against the Arizona Department of Water Resources (ADWR) over its adoption of a controversial 33.3% groundwater tax. Carbone claims that this policy is driving up the cost of housing and ultimately harming Arizonans who are already grappling with soaring housing prices.
At the center of the dispute is a policy known as the housing moratorium, which has been criticized for preventing the development of large swathes of land that could otherwise be used to build affordable homes. According to Carbone and other critics, the moratorium was adopted illegally, and it has led to a situation where hundreds of thousands of acres of land remain undeveloped. This, in turn, limits the amount of available space for new homes, driving demand to already crowded urban areas and increasing housing costs.
Carbone explained that “water policy is land use policy, and land use policy is housing policy,” suggesting that the restrictions on land development, while related to water conservation, are having broader economic consequences.
As a result of the moratorium, many Arizonans are facing higher costs when it comes to purchasing new homes. The housing moratorium is expected to increase home prices by $19,600 to $23,700 per house. Additionally, the proposed 33.3% groundwater tax has been predicted to add an extra $5,100 to $7,900 to the cost of new homes. These measures have raised concerns about the affordability of housing, especially in a state already struggling with rapid population growth and a housing shortage.
The Arizona House of Representatives, alongside the Home Builders Association of Central Arizona (HBACA) and members of the Arizona Senate, have joined forces in a legal battle against the ADWR’s actions. The lawsuit seeks to halt the 33.3% groundwater tax, which lawmakers argue is not only illegal but also harmful to Arizona’s housing market. Carbone criticized the governor’s policies, stating that they are not about ensuring water security but rather a means of “government control.”
“The Governor wants to dictate where and how Arizona families live, limiting all future growth to cities and driving up home prices,” Carbone said. “Affordable housing is central to the American Dream, and we are committed to fighting these illegal policies that will only make the housing crisis worse.”
The legal battle focuses on the ADWR’s authority to implement such a tax and whether it complies with state law. Proponents of the lawsuit argue that homebuilders have long demonstrated a commitment to responsible water management, having replenished 100% of the groundwater they use annually since 1995. Therefore, they contend, penalizing the homebuilding industry with additional taxes is unfair and counterproductive.

How much water does Arizona currently have? That’s the question on the mind of Arizona lawmakers this legislative session.
Last week, Arizona House Republicans revealed that a small group of legislators had previously sent a letter to the Arizona Department of Water Resources (ADWR), asking the agency “to provide basic information on the following details related to Arizona’s rural groundwater basins:
- The average depth-to-water level in each basin
- The maximum depth of each basin
- The average depth of each basin
- The total volume of groundwater in each basin
- The number of index wells in each basin.”
The letter, which was authored by State Representative Gail Griffin, Senator Tim Dunn, and former Senator Sine Kerr, was transmitted to ADWR on December 23, 2024.
Speaking about the reasoning behind the letter to ADWR, Representative Griffin said, “The intent was to give Arizonans a better understanding of the groundwater supply beneath their feet. For the last two years however, none of the Department’s assessments have included this basic information – such as ‘how much water do we have’ and ‘how long will that water last.’ This information is a fundamental component of the ‘supply’ side of the ‘supply and demand’ equation and needs to be included in each of the Department’s five-year ‘Supply and Demand’ Assessments.”
According to the press release issued by House Republicans, ADWR “provided a preliminary response to the December 23 letter, stating the number of active index wells in each basin and the maximum depth of each basin at its deepest point.” The response shared that the “Wilcox and Gila Bend groundwater basins are 4,800 feet deep at their deepest point.” However, as the release highlights, “The Department has yet to provide the total amount of groundwater that is available to each of these depths.”
Representative Griffin is not at all satisfied with ADWR’s incomplete answers. She said, “Just because you drill a well does not guarantee that there will be one hundred years’ worth of water. Republicans and Democrats both agree we need to know how much water is available in order to make informed decisions on critical groundwater policy. It’s also essential to our ability to plan for the future. How are we supposed to plan if we don’t know how much water we have?”
With these questions in mind, Griffin introduced a bill (HB 2271) this legislative session “to update the 5-year Supply and Demand Assessment statute and require the Department to include this information in its reports, moving forward.” If the proposal was signed into law, it would “provide critical answers to these basic questions, such as, ‘How much water do we have?’ and ‘How many years will that water last at the current rate of decline?’” Answering these questions would allow legislators to “plan to add new tools that work for rural Arizona, such as groundwater recharge, replenishment, and reuse.”
Focusing on her bill, Griffin said, “we understand that additional steps may be necessary to gather this information, but we also believe that taking these steps is a necessity to do our jobs effectively. I think the Department wants to make decisions based on science and that, if we give it the time and opportunity to gather this information, it will result in a better and more constructive dialogue for everyone.”
HB 2271 was approved by the Arizona House of Representatives last week.
