Hi,

It's great that you are mapping the 2D non-routable areas of residential roads, something I rarely have time to do.

However, please could you use area:highway=residential rather than tagging it as a routable highway=service area?

If you use highway=residential + area=yes, iD produces the warning "Residential road should be a line, not an area". Although changing it to highway=service will removes this warning, it introduces incorrect data.

Thanks.
