I think the roads you added should be highway=service. highway=residential and highway=unclassified are typically government operated roads. residential are those in a city while unclassified are residential roads typically found in rural areas. Since these seem to be associated with Scimitar Ridge Ranch, they look more like highway=service. Plus, Skagit county doesn't show them which makes them service roads. 

Can you review this edit and fix the road tags? I'll send you more info on OSM in a message.
