I want to know the answer to the following question:
What change in building heights did Seattle make to increase population density in its downtown ?
All the background I'm provided with is that "However, former mayor Greg Nickels supported plans that would increase the population by 60%, or 350,000 people, by 2040 and worked on ways to accommodate this growth while keeping Seattle's single-family housing zoning laws.". Is that enough to answer the question?
Answer: no
