“IBR’s Supplemental Environmental Impact Statement includes 26 technical reports, but a critically important geotechnical report is missing, and the IBR has offered no explanation. I filed a Public Disclosure Request and obtained IBR’s “Geotechnical Data Report” dated May 2024. This report describes the encounter of many boulders and cobbles in a 200-foot layer of sediment. The report referenced boulders 106 times and cobbles 175 times.  
Shockingly, the IBR has fraudulently disqualified an immersed tunnel alternative that would eliminate the need for drilled shafts. Similar to a floating bridge, an immersed tunnel is supported by displacing its weight, according to Archimedes’ principle. This design is faster to build, could potentially save $1 billion associated with drilled shafts, and would also be more earthquake-resilient than a foundation based on drilled shafts.”
