Together, the two areas include approximately 2,041 residential parcels and an estimated 6,300 residents.
At the same time, Queen Creek is advancing a separate annexation of approximately 6.9 acres at the southeast corner of Ocotillo and Meridian Roads.
What Is a Municipal Planning Area?
A Municipal Planning Area is a boundary shown in a town's General Plan that identifies areas it may consider for future annexation. It is larger than the town's actual municipal limits.
Being located inside a town's planning area does not mean the property is part of that town. It does not mean residents pay taxes to that town, receive services from that town, or are automatically annexed.
Planning areas are intended to guide long-term growth discussions. Under Arizona law (A.R.S. §9-471), annexation requires contiguity and statutory notice and petition requirements. A planning area designation alone does not annex property and does not prevent other jurisdictions from planning for or annexing contiguous territory.
The Two Residential Areas
According to Queen Creek staff, both residential areas were developed under Pinal County jurisdiction and county development standards. They were never part of Queen Creek and did not pay Queen Creek impact fees or development-related revenues at the time of construction.
One area includes 461 parcels, including a subdivision currently under construction. The other includes approximately 1,580 parcels.
Council members indicated that removing the areas from the planning boundary would clarify that Queen Creek does not anticipate annexing them in the future. The General Plan Amendment process to remove the areas is expected to take approximately four months and will include public meetings and hearings.
Why the Timing Now?
During discussion, council members referenced several considerations:
The Town of San Tan Valley incorporated in September 2025 with boundaries smaller than the overall geographic area commonly referred to as "San Tan Valley." Thousands of residents and businesses remain in unincorporated Pinal County outside the new town limits.
If Queen Creek removes the two residential areas from its planning boundary, those areas would remain unincorporated unless another jurisdiction annexes them.
Separate Annexation Moving Forward
In a separate matter, a 6.9-acre property at Ocotillo and Meridian Roads is moving forward in Queen Creek's annexation process. The annexation ordinance appears on the March 4, 2026 consent agenda.
Town documents indicate the applicant intends to pursue a commercial rezoning request following annexation.
A public hearing on the annexation was previously held in November 2025. One neighboring resident spoke in opposition at that time, expressing concerns about potential future commercial development in the area.
The annexation ordinance itself was not voted on during that earlier hearing and is now scheduled for council consideration.
What Happens Next?
For the planning area removal:
If approved, the two residential areas would no longer appear within Queen Creek's Municipal Planning Area in its General Plan.
The Ocotillo and Meridian annexation remains a separate action and will follow its own statutory process.

SAN TAN VALLEY, Ariz. — Firefighters were dispatched to a Walmart in San Tan Valley on Wednesday for reports of a fire burning inside the store.
Rural Metro Fire said the agency responded to Walmart on Hunt Highway after sparks started a fire in the store's paper towel section. The sparks had reportedly come from some welding being done on a nearby appliance, the fire department said.
The fire was quickly extinguished, but the flames caused some damage to the store's paper products.
Rural Metro Fire said one person reported sustaining a minor foot injury during the incident.
