Starting with the street sign wall. Our sister site Central District News reminds that you can buy retired street signs from the City of Seattle for $5-$10 each from the city surplus warehouse:
They’ve got a full list of which signs are available, and if you see one you like, just go down to the city surplus warehouse at 3807 Second Ave. S (just south of the Spokane St. viaduct) and you can get them for $5-$10 each. But be patient if you see the ones on your block were recently switched out. The warehouse staff tells me that it takes a couple of months for the old signs to make their way from the transportation department to the surplus store. Call or email the warehouse if you have any questions.
That’s interesting that they vary in price. Is this due to the popularity of certain streets over others? Pike and Pine go for 10 but Malden or 14th only go for 5? I’d love to see the Hill’s street heirarchy.
