Overview
- The Superior Town Council unanimously approved the agreement on Thursday, May 28, 2026, committing more than $20 million in water mitigation and community investments tied to the Resolution Copper project.
- The multi-part mitigation package calls for restoring and enhancing flows in Queen Creek, removing debris and invasive plants, and rehabilitating the town's infiltration gallery to better capture and return water to the creek.
- The deal creates a $5 million endowment for long-term restoration and conservation, transfers water-storage credits to the town, and includes infrastructure investments intended to support an assured water supply for future growth.
- Town and company officials described the pact as the result of years of scientific studies and technical reviews and said it includes long-term monitoring and mitigation commitments for the life of the mine.
- Officials said the water for restoration will come from multiple sources, including treated groundwater from former farm wells, and that renewed flows could boost riparian habitat, local recreation and the town's water security.
