text: I think `except=residents` would be descriptive. The city uses abutters here, which I think is just to be distinct from the "resident parking" meaning "resident of the city".
  
  `except=residents` is pretty infrequent, based on taginfo, but we do have another use of it in the city for Endicott Ave, which has the same restriction time period https://www.openstreetmap.org/relation/12548406
