Matt:
I am home, so a couple of answers and then I'm off to bed.
We do not look for property that fits our design style. We look for property that offers opportunities to build something different.
We've done a few courses with residential development. Riverfront, as Carl Rogers would attest to, is overwhelmed by the houses because it was built through soybean fields and there was no mature vegetation to separate the golf from the housing. Can't win there. However, I am extremely pleased with the work we did at Tumble Creek in Washington ... the course is integrated with a residential development, but the houses are mostly hidden by setbacks and by mature trees, and there are enough places where the holes come together in big open spaces that it doesn't feel like a residential course at all. I think the project we're building near Bend, Oregon also has a fine land plan (because I did a lot of it myself). And even Quail Crossing in Evansville works pretty well at integrating golf and housing, though I haven't seen it for 7-8 years and I don't know if the houses are starting to swallow it.
There are certainly other good examples -- one of the first, St. George's Hill in England, is a good sight better than Tumble Creek, Cuscowilla or Wade Hampton.
