Maricopa County has approved a pair of land-use changes covering nearly 900 acres around 411th Avenue and Camelback Road, clearing a major entitlement hurdle for a proposed far West Valley development that could eventually combine data centers, industrial space, entertainment, hospitality, retail and residential uses.
The two sites sit in the Tonopah area near Interstate 10, roughly an hour west of central Phoenix. On Sept. 2, the Maricopa County Board of Supervisors considered the Balterra and Camelback Creek cases, both tied to land controlled by entities associated with Arizona Land Consulting. The county actions changed the properties from rural designations to mixed-use and industrial zoning with an Industrial Unit Plan Development overlay.
The larger Balterra property covers about 590 acres southeast of 411th Avenue and Camelback Road. The Camelback Creek case covers about 310 acres at the northwest corner of the same intersection. Together, the two sites total roughly 900 acres.
County records show the Planning and Zoning Commission recommended approval of both cases on Aug. 6 by 7-0 votes. The Sept. 2 Board of Supervisors agenda included the corresponding comprehensive-plan amendments and zone changes, including cases CPA260007, Z260018, CPA260008 and Z260019.
What the zoning allows
The approvals do not authorize immediate construction of a specific theme park, studio or data-center campus. They establish the land-use framework for future development.
County conditions allow buildings up to 85 feet tall on the industrially zoned sites and set a reduced parking standard of one space per 2,500 square feet for warehouse and data-center uses. Screening requirements include six-foot masonry walls, increasing to eight feet where the sites border rural or residential zoning. Camelback Creek also carries a minimum 50-foot landscaped setback along its northern boundary.
Further development will require administrative Plans of Development before construction permits can be issued. County conditions also require utility coordination, grading and drainage work, traffic studies or analyses as projects advance, fire-service confirmation and an archaeological or historical review before grading.
Water and wastewater remain important practical constraints. Maricopa County does not provide water, fire or sewer service to the properties, leaving the developer responsible for securing those services. The Camelback Creek conditions state that a public water system must be available before establishing non-residential uses that require potable water. Until sewer service is available, uses must also be compatible with on-site wastewater systems accepted by the county.
A much larger concept is being discussed
Arizona Land Consulting CEO Anita Verma-Lallian has described a broader concept for the land that could cost an estimated $6 billion to $10 billion if fully developed. Reporting by the Phoenix Business Journal and other Arizona outlets says the vision includes a movie-production studio, amusement and indoor-theme-park uses, hotels, retail, multifamily housing, distribution space and a large data-center component.
Those elements should still be treated as a development concept rather than a final construction plan. County records state that a detailed Plan of Development has not yet been approved for the full buildout, and the exact mix of uses, infrastructure, phasing and construction schedule can still change substantially.
The location is notable because 411th Avenue has increasingly become a focus for large land and infrastructure plays in western Maricopa County. Arizona Land Consulting has assembled several large properties in the Tonopah area, while other investors have also positioned land around future transportation, utility and employment growth farther west of Buckeye.
The next meaningful milestones will be the filing and approval of detailed development plans, confirmation of water and power capacity, roadway requirements and any announced end users or tenants. Until then, the Sept. 2 approvals are best understood as a major entitlement step rather than a construction start.
