The authors contend that the project threatens the Redwall-Muav regional aquifer, which supports critical springs in Grand Canyon National Park and the water supply of the Havasupai Tribe. They further argue that the development would cause light and noise pollution, overwhelm park infrastructure, and harm wildlife habitats, including elk calving grounds and antelope fawning areas.

The report highlights a significant reliance on groundwater, often from deep and costly wells, and the critical role of wastewater reclamation in communities like Tusayan, where it meets 40% of demand. It identifies a wide disparity in conservation efforts, with Flagstaff having the most extensive program and Page lacking a serious initiative.
