I would actually not use the JW-SAZ as an example of a code that supports the development of different housing forms.  First off, since the code was passed, there seems to have been exactly one unit added to that area.  It doesn't seem to be supporting the development of different types of housing.  Second, the code itself, though the lot size requirements and other restrictions, make it impossible to build townhouses and triplexes, which are appropriate missing-middle types for medium-density residential (which is what that area is in the Metro Plan.)  That code might be achieve some goals, but not of supporting different housing types.

I think staff have had to shift focus from the key transit corridors because instead of being willing to engage in a reasonable discussion about how the code did or didn't accomplish the goals set out and what modifications might be need be worked out to improve it, Council decided to pass Mike Clark's motion and completely change direction.
