With that letter to neighbors of the triangle at SW Hill/44th/Ferry (map), the city has announced that two halves of a trailer for interim Fire Station 29 will arrive tomorrow morning. Two trucks will bring the two 14-by-66 halves to the site by 6 am, according to the letter. It’s been just a month since neighbors were suddenly notified that the interim station was moving onto this site during its upcoming renovations and earthquake-safety upgrades, instead of using the long-planned Harbor Avenue site that had been home to Station 36 during its renovations. The city said the change was needed because the response time from the Harbor Avenue site would have been too long. Neighbors will be watching warily to see if their safety concerns are handled, since the site will be a tight fit. The work at permanent Station 29, barely a block south, is expected to take much of the rest of the year. Meantime, the city also is getting ready to move Station 32 out of its Triangle home at 37th/Alaska for a full rebuild; we had timetable details in our most recent update on the 32 and 29 projects.
