You might consider a call to the Local POCO, 100' seems a pretty long way, or maybe their requirements are on the I-net. I'll bet that you'll have to go with an additional pole.
I'd think they have calculations for their loops and wire gauges verses the service requirements. While we have to be a miminum above a structure, you'd have to add addition length to match their application.
Who owes the service drop, is it up to the weather head, or through the meter, it all varies to the POCO?!
If you are even thirsty, you are two quarts low.
