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: 1/7 #seattle6
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
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. 3/7
It doesn’t preserves open space-but breaks up useful backyard space in to useless sideyards. It orients spaces toward neighbors rather than street or yard. Less eyes on street. And we lose more mature trees in the process
‘Gentle’ upzoning kills yards, not preserves them. 4/7
Side to side #seattle6, 8 or 10 unit ‘plexes trade sideyard for backyard. Every one of these flats looks out to street, yard or both. Yes, there is more shadow for old houses, but we’re not pitting people who need place to lives against trees & open space 5/7
In terms of number of households, we’ve gone from 20 to 48 (in the ‘gentle’ density sketch) to 70 here, but we haven’t eaten up the open space or exhausted the development capacity. 6/7
The progression after a few generations is a new pattern that balances housing and open space.
I’m not inventing anything new here-this is an ancient and popular way of living common in cities around the world-just we might not see how to get there from where we are today.
7/7
PS:
Put three of these blocks together, and you have enough kids to have a new daycare
Put six of these blocks together and have enough people for a cafe
Put ten of these blocks together, and you have enough for a 15 Minute neighborhood and lower carbon lifestyle for all.

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)
