From June, a summary of the zoning code that allows this form of "congregate housing", a bit of history of how it got started in Seattle and current/future projects.
Embedded in this more recent opinion piece is a link to some channel 13 coverage:
The comments on both of these are interesting -- chrismealy is a coworker of mine from my days at a little internet bookstore. I agree with him that quoting Hayek doesn't make you look good; acting like liberalizing zoning laws is somehow incompatible with being in favor of public transit seems a little extreme. OTOH, it would be nice to hear the political value system that supports both simultaneously, and it is rarely articulated well (that doesn't make it bad -- just poorly articulated).
ETA: Menino in Boston is interested -- as well he should be.
