What is the proper layout and placement for a stop sign and street sign on a single post?

Stop signs should be placed so that the sign roadside edge is at least 6-12 feet from the edge of pavement, with a 2 foot minimum for curbed roadways. Placement of the stop sign is to be on the right side of the roadway at either the stop line or (4) feet in advance of a crosswalk. If there is neither a stop line nor a crosswalk the sign should be placed where traffic can stop and clearly see both directions before entering the intersection, and no greater than 50 feet from the intersection.

Street name signs may be placed on the same post and above the stop sign, provided it does not distract drivers away from the stop sign, and remains visible from the main road. Sign heights, the distance between the ground and the bottom of the sign, vary depending on the area. Minimum sign heights are 5 feet in rural areas and 7 feet in urban areas. This additional height is to accommodate pedestrian passage without interference.
