S-zation
I live too far to survey this one, so it needs to stay open.  I wouldn't change the name based on search results, especially since Chalfont is the name of a town 60 km northeast of here and is unrelated.
It needs to be surveyed both at the 4-way intersection with Little Conestoga and Marshall and at the intersections with residential roads.  I've seen some Pennsylvania townships give two different (but very similar) names to the same road on road signs.
