_"Eugene’s apartment dwellers will be hoping to save enough to move out of Eugene"_ -- Henry Licks

You are largely right. "Metro" has figured out, and now includes in their computer modeling software, that constraining  developable land increases housing costs and leads to shift in demand. Among the most important strategies to mitigate this is _pragmatic_ approaches to supporting alternative forms of housing (e.g., courtyard cottages) that can be profitable at a reasonable cost and that have function and features that appeal to at least some segment of the "single-family housing" market.

As I explain above, Eugene Planning staff have done nothing but produce marketing hype and a disastrous, sweeping zone change that would have accomplished nothing other than net loss of some affordable single-family homes in a close-in neighborhood.
