text: The admin boundary here is for a neighborhood, not a municipality. I have been using roadways as members of relations for neighborhood boundaries, as they are typically more informal and do actually follow roadways directly (whereas some municipal boundaries only contain part of the right of way for a road). I hope this helps explain some of the boundaries for these kinds of relations in the area (note: they should be tagged with admin_level=10 and place=neighborhood). Feel free to message me if you would like further clarification!
