to do so. We design them to avoid differential settlement (where different areas or different structural elements settle at different rates), but I don't see any evidence that the stadium is experiencing significant or adverse differential settlement.

The soils present below the stadium aren't unstable. I've performed and managed geotechnical investigations in the area for nearly 30 years, including a couple projects immediately adjacent to the stadium. The soils in that vicinity have always consisted primarily of unsaturated (to at least 18 feet), interbedded sands and gravels. They are the opposite of unstable. I've watched drillers hit layers of cemented gravels on the northern side of Stadium Avenue so dense they had to bring in an odex rig to break through it.

While I wouldn't exceed structural loads of 6 to 7 kips per linear or square foot on the native soils, it would be a fairly straightforward affair to engineer footing areas to accommodate significantly higher structural loads in that area. There are heavier buildings constructed on far worse soils in this valley. It could absolutely be done.

Also, there isn't a fault running through or near the stadium. The nearest splay of the Wasatch Fault is almost a mile east of the stadium.
