Although Hanse is popular for just about any type of project currently, it's worth noting that he and his team have proven themselves to be quality hires for flatter sites. Rustic Canyon, Rio's Olympic Course, Ohoopee, and PGA Frisco are all on sites that don't exactly command attention in their unadulterated state, but can still yield compelling, strategic golf.
I could be wrong--I hope I'm not--but I very much doubt this Coachella project will resemble Shadow Creek or Madison Club mentioned on this thread. When I consider Hanse's work, he, much like Doak and Coore/Crenshaw, are attentive to their course's sense of place. Tie-ins to the natural surroundings are important in terms of contour, horizon lines, and vegetation. I would expect there to be expanses of scrubby, sandy waste areas around grassed corridors, and most plantings to be consistent to what is native to the surrounding desert.
This sounds very much like an "Ohoopee Match West" to me, in terms of club structure and the kind of golf that might be built. While its construction won't dissuade those who fundamentally think golf in the desert is an oxymoron, I'd love it if the end result helps push desert golf towards a more naturalized embrace of its climate and aesthetic, as opposed to being another overly watered fabricated oasis pretending to exist somewhere it shouldn't.
