The wiki documentation for lanes does not specify that roads must have lane markings to be marked with a lane count. It does however state I should have added the road width as measured to make the tag narrow more useful. 

The road itself is wide enough to be a two lane road, however with street parking it narrows to a one lane road, hence the narrow tag.

I can not readily find the link now but I did read that two lane roads with street parking should be mapped as two lanes and narrow. 

The stop sign was obviously in err. The way for 13 street is in the opposite direction of East 13th street, I likely saw the direction of 13th street and did not realize the transition to East 13th flipped direction. Someone with a drivers license would in fact detect this as an error in direction and probably not follow directions to stop.
