Update: The current Yesler Terrace project is 22-acres. The redevelopment is expanding it to 30 acres. So I’ve updated the math. Point still holds.
The Seattle Times ran an article about concerns over the Yesler Terrace replacement project. What jumped out at me:
[Hired land use consultant Matthew] Gardner is skeptical that Yesler can capture 10 to 15 percent of new residential development citywide, which he says the plan calls for. But Heartland points out that Belltown grabbed 22 percent of the city’s new housing in the 1990s.
Yesler Terrace is 22-acres, or about 3.4% of a square mile[1] 30 acres or 4.7% of a square mile. With 5,000 units and assuming only one person living in each unit[2], that’s a residential density of 145,455 106,667 people per square mile, more than twice one and a half times the density of Manhattan. The project will also have a good deal of office space, some open space and a community center.
The city can plan on putting 10-15% of new residential development citywide[3] on 3.4 4.7% of a square mile and 0.04% of the city’s area, with mostly mid-rise buildings, through the magic of density. In Black Diamond, 6,500 units are being built on 1,500 acres. I know I’m preaching to the choir, but this is why dense construction near transit is so important. Though we are building rapid transit access to only a small portion of a the city, it clearly could be very easy to accommodate all new housing construction in just the planned Link station areas. Sadly, we are mostly getting new parking lots and vicious fights.
1. It is possible the development project is larger than this, though I cannot find evidence of that.
2. Obviously there will be more than one person per unit.
3. I am not sure what time frame that is supposed to be over.
