Someone decided at some point that it wasn't important for new developments in Seattle to have much (or any) parking. In some places this ok, the transit is decent and there's a lot of things within walking distance. In other places it's not ok.
Our transit system as a whole is insufficient. While there are plenty of things it does right, there are too many things it does wrong. And there's a consistent problem of getting enough funding. Each time a new ballot measure comes up to add light rail or add bus service, you get a huge outcry of "just build more roads." The problem is, there's no room for more roads. The city is situated on a narrow strip of land between Puget Sound and Lake Washington with the densest parts of the city falling in the narrowest parts. There's also the fact that building more roads or more lanes is incapable of solving the problem. Demand will increase far faster so that by the time the new lanes are complete, there's an even more severe traffic problem.
Then you have an us vs them mentality in the state where it's the rural areas vs the city of Seattle which further complicates funding. And you have an American populace only slightly more willing than the average American to give up on or reduce their use of a personal vehicle.
But back to this building. It's not too far from the city's only light rail line and major bus thoroughfare and not a terrible walk from stores, restaurant, jobs, etc.
