I don't think the Carson site was ever really a viable option. It's 167 acres of landfill they would be building a stadium over. We have roads here in San Diego that were built over old landfill area, and the roads constantly have to be filled in where it keeps sinking. I can't imagine what it would be like building a stadium on such unstable ground. I guess that's why engineers get paid the big bucks, but it's a very scary proposition, IMO. Pier construction with grade beams, it's done all the time. Bigger issue will be clean up of the brown field
