be washed out, special precautions shall be taken to ensure durable pole
foundations, and the setting depth shall be measured from the lower side of
the pole. Holes shall be dug large enough to permit proper use of tampers
to the full depth of a hole. Earth shall be placed into a hole in 150 mm 6
inch maximum layers, then thoroughly tamped before the next layer is
placed. Surplus earth shall be placed around a pole in a cone and packed
tightly to drain water from poles.

Cast-In-Place Foundations
Concrete foundations, sized as indicated, shall have anchor bolts
accurately set in foundations using templates supplied by the pole
manufacturer. Concrete work and grouting is specified in Section 03300A
