Landowner notification letter
Developer notice dated July 31, 2026, with the project meeting details.
Protect native habitat.
Keep Open Spaces Open.
Thousands of acres of open Sonoran Desert near Robles Junction and Three Points could soon face a Conditional Use Permit request for an industrial-scale solar project. This land is not empty. It is wildlife habitat, open desert, rural landscape, and part of what makes Southern Arizona worth protecting.
This effort is about protecting precious wildlife habitat and keeping Robles Junction from becoming an industrial solar field.
Next community meeting: Wednesday, October 21, 2026, 6pm, at Serenity Baptist Church.
Our Position
There are places that a solar farm shouldn't be, and this is one of them.
We are not against solar. We are for putting it in the right place, where the land can handle it and the people who live nearby want it.
Recent Updates
Recent project updates.
Members of the alliance report that Tetra Tech crews have been in the area doing environmental survey work for Repsol/CG Three Points. That means the permit information could drop at the county level at any time and start the clock on public hearings.
Call to Action
Contact the full Pima County Board of Supervisors
Please politely and accurately voice your opposition to the proposed solar farm and ask every supervisor to protect Robles Junction, Three Points, rural communities, and open desert habitat.

Why This Place Matters
Open desert is not empty land.
The land around Robles Junction and Three Points is more than vacant acreage on a map. It is part of a larger desert landscape shaped by native grasses, ironwood, mesquite, cactus, seasonal blooms, wildlife movement, rural communities, open views, and the natural character of Southern Arizona.
Native Habitat
Mule deer, javelina, raptors, reptiles, pollinators, and countless desert species depend on a living plant community of native grasses, ironwood, mesquite, palo verde, cactus, shrubs, and seasonal wildflowers. Once habitat is broken apart, it rarely returns to what it was.
Rural Character
Families in this area chose open skies, quiet roads, dark nights, and room to breathe. A project of this scale would permanently change the character of the surrounding community.
Native Plant Communities
This landscape includes washes, grasslands, ironwood and mesquite stands, cactus, shrubs, and seasonal blooms that hold soil, shelter wildlife, and help the desert recover after rain.
The Issue
A Conditional Use Permit could arrive at any time.
The project may soon move forward as a Conditional Use Permit (CUP) request at the county level. Once filed, that could start the clock on public hearings where residents need to be ready to show up and speak clearly.
The proposed Repsol project would convert thousands of acres of open desert and rural land into an industrial energy facility. This is not a small neighborhood project, and it is not a temporary use. A permit request of this size could reshape the future of this landscape.
Alliance members have reported Tetra Tech environmental survey activity for Repsol/CG Three Points in recent weeks. That field work is a warning sign: permit details could be submitted at any time.
This land supports wildlife habitat, open views, rural neighborhoods, and the natural character people associate with Southern Arizona. Once a place like this is industrialized, the decision is difficult - and often impossible - to undo.
We oppose any permit approval that would put an industrial solar field on precious habitat that should remain open, connected, and alive.
Now is the time to learn what is being proposed, contact county decision-makers, and help protect this habitat before hearings begin.
What Is At Stake
Z
Stay Alert for a CUP Request
Project proponents may seek a Conditional Use Permit for industrial-scale solar development.
A
Not Every Open Space Is An Industrial Site
The scale and location would permanently alter open desert and nearby rural communities.
L
This Is Not Empty Land. It Is Habitat.
Open desert supports native wildlife, movement corridors, scenic character, and community life.
What We Believe
Protect Open Desert Habitat.
Open Space Alliance believes the open spaces and wildlife habitat that make this region unique should not be sacrificed for an industrial solar field.
- Protect native wildlife habitat.
- Keep open desert connected.
- Respect rural communities.
- Listen to local voices.
- Do not turn Robles Junction into a solar field.
Wildlife & Conservation
This is habitat, not empty space.
Southern Arizona's open spaces are living landscapes. They provide food, shelter, movement corridors, and seasonal range for native wildlife. Mule deer and other species do not move according to property lines or zoning boundaries. They depend on connected land.
When large open areas are fragmented, wildlife is pushed into smaller and more stressful spaces. Roads, fencing, grading, lighting, and industrial infrastructure can all change how animals move, feed, and survive.
Some places carry value beyond what can be built on them. This open habitat is one of those places.
Once open habitat is gone, it is hard to get back.
Mule Deer Habitat
A home that cannot simply be rebuilt.
Long before roads, utility corridors, or zoning maps, mule deer moved across Southern Arizona's valleys, washes, and grasslands. These landscapes give wildlife room to feed, shelter, travel, and survive between mountain ranges.
For many Arizonans, seeing mule deer at sunrise or watching a small group move across an open wash is part of what makes this place feel like home. It is a reminder that wild spaces still exist close to our communities - and that they are worth protecting.
But habitat does not survive in isolated pieces. When open land is broken apart by large-scale development, wildlife loses more than acreage. It loses connection, movement, cover, and safety.
This effort is about protecting a living desert landscape and the native species that were here first.
Some places should remain open because they are already serving a purpose.
What We Oppose
Robles Junction is the wrong place for an industrial solar field.
We oppose the proposal because of its scale, location, and long-term impact on open space, wildlife habitat, and nearby rural communities.
This project would not just place solar panels on unused land. It would transform a large open desert landscape into an industrial energy site. That kind of decision deserves careful scrutiny, public input, and a serious look at better alternatives.
- We oppose industrial-scale development in sensitive open space.
- We oppose the permanent loss and fragmentation of native habitat.
- We oppose putting an industrial solar field on precious habitat.
- We oppose decisions that dismiss local concerns.
- We oppose rezonings that permanently transform rural communities.
- We oppose treating open desert as empty land simply because it has not yet been developed.
Some places should stay open. Some projects need better locations.
Join the community meeting, review the maps, and help neighbors understand what is at stake.
Protect Habitat
Precious habitat should not become a solar field.
The open desert around Robles Junction and Three Points is habitat. It supports mule deer, desert species, open views, dark nights, and the rural character of the surrounding community.
A solar field of this scale would bring grading, fencing, roads, lighting, and industrial infrastructure into a landscape that is still open and alive.
Once habitat is broken apart, it rarely returns to what it was. The decision before the Board is whether this open desert should remain habitat or be permanently converted into an industrial energy site.
Robles Junction should remain open habitat, not an industrial solar field.
