Light Pole Base Detail

Taper Concrete Cap 4" Min, 6" Max - 24" Square Cap Poured after base is installed
Provide Detail for Square Cap
DOT Response
The 1” taper can be grout or concrete over top of the cap, or the taper can be shaped into the top of the cap.
A circular hole drilled with an auger for a 24" round base is acceptable. The '24" square' refers to the exposed 4" to 6” above finished grade. This could be done by using 2x10s or 2x12s for the forms with 4" - 6" exposed and the rest below finished grade.
