City of Overland Park Guidelines for Installation:

“Type 4 Object Markers” (OM4-3) will be installed at locations where the roadway ends abruptly. This does not include cul-de-sac bulbs. Typically, instances were the roadway could possibly end abruptly are temporary situations between construction phases in residential development. However, due to changes in development patterns, economic conditions or other changes, the condition may last permanently.

Multiple signs should be installed on separate posts, within two feet from the end of the paved surface, across the entire width of the roadway such that the spacing between sign posts and the spacing between the outside sign posts and the back of curb is less than 6 feet.

Signing Standards:

The “Type 4 Object Marker” (OM4-3) sign shall be an 18” x 18” diamond sign with red retro-reflectorized sheeting.
