Hey OSM-SAMOA,
Thanks for your continued contributions in Samoa. I noticed you reclassified some residential ways to secondary in the following changesets: (https://www.openstreetmap.org/changeset/169424331, https://www.openstreetmap.org/changeset/168116396). According to OSM guidelines, secondary highways are typically paved and support higher volumes of traffic (https://wiki.openstreetmap.org/wiki/Tag:highway%3Dsecondary). I also noticed you added a connecting highway (https://www.openstreetmap.org/way/1413374851), but there doesn’t appear to be any visible dirt or paved road in the imagery. The way crosses through tree cover, and the intersecting roads don’t show viable connections in imagery.
I also noticed you added a layer=-1 tag to some highways (https://www.openstreetmap.org/changeset/168672202, https://www.openstreetmap.org/changeset/168116431) which are typically used to distinguish overlapping features (https://wiki.openstreetmap.org/wiki/Key:layer). Based on aerial imagery, the highway in question appears to pass near, but not under, the building at https://www.openstreetmap.org/way/1104358932.
Would you be able to share the justification behind these modifications?

I look forward to hearing from you.
