I wouldn't use boundary=admin with admin_level unless there is actually a hierarchical relationship with the levels above/below. Otherwise they should really be in their own hierarchy, using something like boundary=fire_service. AIUI the US fire departments are at the city or county level. Can a city/county have more than one FD within its borders? Can an FD's jurisdiction extend across local government boundaries?
The points I'm trying to make are that: 1) a fire district is not a unit of local government, so it doesn't fit naturally with boundary=admin 2) the use of admin_level (the "level" bit) implies a hierarchy which may not be the case. The basic hierarchy is that the US consists of States which consist of Counties which have Cities (yes I know it's more complicated than that in practice). A City may have fire districts, but it may also have suburbs, police precincts etc which have little or no relationship to each other in terms of boundaries, although they are all subsets of the enclosing City. Perhaps all of these should be the same admin_level, one level below the city, with some distinguishing tag to separate police areas from fire etc. Excuse me if I have misunderstood (I am not an American) but I am just trying to keep different concepts separate, avoiding reuse of tags for conceptually different things because it seems "easy".
