ffej010,
You are 100% correct, horizontal boring 100 feet can easily be done in one shot. I was thinking of a worst-case situation where there might be obstructions [like a huge pipe] that couldn't be gotten around [I was in "worst case mode" when I wrote that].
Also, I should mention that public utility companies [water, electric, etc.] around here don't usually have to go through the brutal approval process I described. That only applies to a private entity seeking to dig up a highway.
