Seattle here. The problem isn't that there's too little "planning" or "zoning". Where that's relevant, there's too much. The city has used those tools over and over to slow growth and tack on requirements for businesses.

I'm not aligned with the new mayor's business-hostile policies. But as far as making the city better for walking, things are going very well. We've been narrowing crossing distances, improving sidewalks, putting in concrete separation for bike lanes, we even finally kicked cars out of Pike Place Market. There are parks improvements in progress across the city to improve restrooms and fix dangerous spots. And the number of people in tent encampments has dropped dramatically, it's become rare and short lived in most of the city.

I suspect that we will continue to recover, despite the capital gains tax. It'll just be slower than Bellevue.
