I want to illuminate why relying on additional upzones in the urban villages or tweaks to their boundaries is not the way forward given Seattle’s projected population growth and our current housing price spike. 1/8 Image
For context, King County is projected to add nearly another Seattle in population in the next 25 years (nearly 700K) and the region will add 1.8 million people. 2/8
Our current #OneSeattle housing target is 112000 homes over twenty years, but the reality is we need to have about double that to meet demand and address affordable housing. So how do we get there? 3/8
When people come they either find big box apartments, townhouses or houses to buy or rent, or ADUs. There aren’t other choices that are allowed by zoning or built by either the private market or public subsidies. And we aren’t producing enough for everyone to live close. 4/8 Image
There is a shortfall. Either richer folks are competing for scarce housing and displacing more vulnerable folks, or they are choosing to live so far away that housing prices are affordable. 5/8 Image
From a planning perspective, the solution is to provide more opportunity for new housing via upzones. But the urban villages have already been transformed & layered over w/ additional upzones. Any further upzones of UVs are inactionable hypotheticals that exist on paper only. 6/8 Image
However, creating capacity in a more distributed way and more than you think you’ll need reduces competition for any one parcel and short circuits bidding wars over scarce land.

It is easy to see how one or two lots would be right for new infill—proper zoning, econ feasible, owner willing
& dev ready—to make up for housing supply shortfall. And the zoning doesn’t have to change too much to make it happen and be great!:

Case Study-Jansen Court by CAST architecture
Single stair, 4 story (1 down) 10 unit studio apt, developed on the back half of a 30' lot.

The complexity of regulations are magnified on a small project, making it quite the puzzle. We are right up against nearly every code limit.
First, site design: setbacks, facade length, exiting and amenity areas dictate the footprint.
The staircase, exiting, and the specific requirements for small efficiency studios drive the plan layout (these are early drawings so there are some deviations in the final building).

Evolving as we grow:
For the #SeattleCompPlan one big question is how to make room new people, fight climate change and undo inequities baked into Single Family vs Urban Villages.

We shouldn’t expand urban hubs, we should rethink all of it. Here’s one way:

people might be shocked at a proposal to eliminate side yards in SF zoning, citing lost of trees, daylight, open space

Let’s assume we add new a ton of new households, what is the best outcome for a livable, sustainable land use pattern?

Start with a typical block:

2/7 Image
Seattle’s narrow deep lots create opportunity in the back yard for trees, gardens, recreation.

But w/ small bumps in households per parcel, like DADUs, the only place to add housing is in the backyard. If the site is redeveloped as townhouses, most new units face sideways.

Reforming Seattle’s Single Family Zoning: Three Truths:

Truth 1) We've outgrown the urban village strategy.
It has been a great success for locating 80% of the housing built over the last 20 years in proximity to transit, but we can't expect the same 6% of land to house the next generation of Seattleites--at least another 100,000 people by 2040. (Seattle Planning Commission)

2/
Urban villages are too small, too few, and the edges are highly contested because we’ve struck such a stark line between what is allowed inside or out. It is a equity issue now, and will get much worse. (image is of relative density across UV boundary street)
