Palo Verde Solar Facilities: Designing for Scale in a Complex Desert Environment
Near the Palo Verde Nuclear Power Plant, large-scale solar development is helping meet growing energy demand across the region. Spanning more than 5,500 acres, with an additional 3,500-acre expansion, this project represents a significant step toward increasing renewable energy capacity while making efficient use of available land.
At this scale, success depends on more than layout. It requires a deep understanding of how the land behaves, especially in a desert environment shaped by drainage patterns and flood risk.
Siting Infrastructure Around Natural Constraints
Our team supported the project with comprehensive civil design and entitlement services, beginning with rezoning and advancing through detailed engineering and construction documentation. A key component of the work involved hydrologic and hydraulic analysis to understand how water moves across the site.
Using advanced modeling, we evaluated 100-year storm events, mapped existing washes and floodplains, and identified areas that could safely support solar infrastructure. With multiple FEMA-designated floodplains crossing the property, careful siting was essential. Design considerations included elevating arrays and incorporating scour protection to ensure long-term performance.
This approach allowed the project team to avoid high-risk areas while maximizing usable land, balancing efficiency with resilience.
Advancing Renewable Energy Through Coordinated Design
Our work included preparation of site plans, grading and drainage designs, and supporting documentation for entitlement and permitting through Maricopa County. Traffic evaluations and early-phase planning materials helped move the project through approvals and into implementation.
With a combined capacity of approximately 1,000 megawatts, the facilities are capable of powering hundreds of thousands of homes. The project demonstrates how thoughtful planning and engineering can unlock the full potential of large-scale renewable energy development while responding to the realities of the landscape.
