In 1998, an Arizona man secretly cut holes through Tucson’s street curbs to steal stormwater; the illegal experiment eventually changed city policy

The grass is not always greener on the other side; sometimes it's greener where you stop the water from leaving. In 1998, Brad Lancaster, the author of “Rainwater Harvesting for Drylands and Beyond,” quietly drilled 6 holes in the concrete curb out front of his house, which would allow him to "steal" rainwater before it disappeared down the storm drain inlets. He later elaborated this concept in his writings, where he identified the problem of viewing rain as a burden rather than as a resource in cities. About twenty-eight years later, as recounted in a 2026 Substack article titled “The Man Who Farms the Rain,” those curb cuts were a vivid demonstration of civil disobedience exposing the inefficiency of the law against ecological common sense.

The crime scene: a desert city throwing water away

At first glance, Tucson, Arizona, does not appear to be a land of water. The city receives an annual rainfall of only 11 inches, and during rainfall, thousands of gallons of water pour into the drains. The infrastructure in the modern era has relegated stormwater to flood risk, rather than an environmental resource.

But Lancaster's eyes witnessed something unusual. The curbs did not direct water to the trees, shrubs, and native plants that needed it. So he went and got himself a handsaw. After six illegal cuts, the water was no longer draining but running off into shallow planted basins. The city became aware of this only after three years.

An illegal experiment that grew into proof

It was pretty risky, but it paid off well. The narrow alleyway between the sidewalk and street became a flourishing oasis of desert plants. Native plants, such as mesquite, palo verde, prickly pear, and others thrived without municipal irrigation through water that once was considered waste; providing shade, cooling down pavement, enhancing soil, and nourishing birds and pollinators.

It was ironic that the illegal alteration fared far better than the legal structure. Eventually, Lancaster told City officials. Some engineers voiced concerns over roads, roots, and liability; but as the project progressed and was clearly successful, it became harder and harder to completely dismiss it.

Civil disobedience meets climate adaptation

Americans sometimes tend to idolize the rebels when history backs their victory. Many social changes start with people asking themselves if the rules they follow are still in the interest of the public. From Rosa Parks to the environmental messengers, many changes in society are sparked by individuals questioning the role of the rules they are required to follow in society. The case of Lancaster is different; it is not a moral revolution, but an environmental revolution based on a practical observation.

His curb cuts called into question an underlying principle of twentieth-century city planning: get rid of water as quickly as possible. This way of thinking seems to be outmoded today. In the American Southwest, however, stormwater harvesting is becoming more than a curious pastime, but a sensible way of managing the city.

From outlaw to policy influencer

Eventually, the outlaw got Tucson's attention. The city changed its strategy and introduced a new scheme for harvesting stormwater via the curb cuts and also integrated rainwater into the wider sustainability agenda. Workshops were established, and demonstration sites became commonplace, normalizing only this one illegal practice.

Lancaster's secret experiment became the model for planners, educators, and environmental groups throughout Arizona and beyond, and his books became the basis for the principles of working with water rather than against it.

The bigger lesson flowing beneath the surface

The story is a resonating one that poses an uncomfortable question: how many regulations actually outlive the issues that they were designed to address? Cities still operate by engineering standards built for an era of concrete-heavy development and rapid drainage. What is now required is a slowdown, not a speedup of water in the context of climate resilience.

This is by no means a rationale for disregarding regulations. Public infrastructure is there for a purpose. The success of Lancaster’s cut holes, however, makes it clear that governments should take notice of the results of such grassroots experiments when they yield measurable environmental gains. In the end, Tucson did not just legalize a landscaping technique. It adopted a philosophy that rainwater should not go to waste, and that streets aren't just conduits, but that small holes in old rules can allow the possibility for things to flow even more smoothly.
