What year was that building built? The wikipedia article doesn't mention that.
On
this website it mentions a "Period of Significance" from 1925-1949, but not a specific date of construction.
Edit: And if it were to cease operation as a fire station, only keeping the museum in operation, at least the land around it could be better utilized as a park, right? I mean to say that it shouldn't require the surface lot for fire fighters but rather just have a few spots for museum workers. Folks who may visit the museum could find parking elsewhere (for instance, the massive CC parking garage).
