I don't have a plan. I believe both the incoming mayor and the south Eugene city council candidates included affordable housing in their platforms. I'm waiting to see what they come up with. 

There is some state money available for affordable housing, due to bills passed in the last session of the state legislature. They also passed a bill making it legal now for cities to pass inclusionary zoning ordinances, which would require developers to include some affordable housing in their developments. The downtown urban renewal district also now requires a certain percentage of apartment projects getting tax breaks to include some "workforce" housing.

My guess is that the city will need to put some money into this, as they have into "revitalizing" downtown. Since, as you have pointed out, 47 percent of Eugene residents are renters, and rents are too high for a lot of us, something has to be done.
