It means we are all going to experience changes to the way things have been for the last century of Seattle’s housing (limitations) and transportation priorities.
There will be loud protests from traditional homeowners, but we  have  created the housing crisis we now face.  
And neighborhood groups, consistent in their opposition to change, never offer any solutions.  
We are beyond the catch-phrase era of “none will be affordable,” “greedy developers,” “toaster homes,” “ugly boxes,” “scraped sites” and other derogatories.  
Increased density can be achieved with increased canopy.

The future can and should be more equitable.
