b. The communications industry standard for conventional 'telephone poles',
is 10 percent of the total height plus 2 feet; so a 60 foot pole would be at

above ground. 'Conventional poles being SYP, or Southern Yellow Pine, or
Loblolly Pine. Only compacted earth is used, no concrete for normal soil.
Every telephone/power pole I've seen is guyed. If not guyed explicitly,
guyed by the lines that go from pole to pole.
