I did a secondary analysis, which you can see here: https://github.com/sbuss/sf-planning-pipeline/blob/master/Ne... -- scroll down to "Break down by project type" which shows how the category of housing that Jane Kim's Prop C affects has cratered, while the other categories are stable or growing.

Even 18% (now 19%) can't be done at the majority of parcels in the city. I guess it's fine for SOMA, which has the highest land values and transit connectivity of any part of the city, but it doesn't work elsewhere.
