I don't think we should use 9/10 for fire/school/etc. Those are not
necessarily subsets of admin_level 8. If a state has a formal notion of
something less than town (neighborhoods? as Boston and Newton have) as a
*unit of government in general*, then that makes sense for 9. But there
can be a dozen kinds of districts besides fire, like school, water,
sewer, and so on. So the fire district isn't really a
political/governing boundary in the same way.
In Massachusetts, firefighing is by town, with a dozen+ mutual aid
districts that I think are mostly sets of towns. So I can see tagging a
boundary "Massachusetts District 14", or some kind of ref tag with
name/number, and having to make up a scheme for each state's way of
So I think admin_level=9 is wrong for this, and there should be
* boundary=fire_district name="name of district"
Used for entities that have a set of firefighting companies normally
under command command and dispatch, and act in many ways similar to a
town or city department, but with a geographic area of responsibility
that is not a town.
* boundary=fire_mutual_aid_district name="mutual aid scheme"
Used for an area within with there are city/town fire departments or
fire districts, and among which there is a plan for mutual aid. A key
difference between this and fire_district is that there is not
typically common dispatch and command among the district.
A not super clear example is the mutual aid districts sort of listed
Basically each city/town is in exactly one district.
