The clearances are found in A and B

The parameter is found in C Edit: ( inside wall of the pool)

Any of the items with in the a min of 10 ft from highest water level of the pool or to the out side edge of any of the pool structures extending further than 10 feet must maintain the clearances in A and B

Private lines or Utility lines

Private lines or Utility lines

What was stated above is from a NEC perspective, but if
these are LV utility lines the clearance is 14ft. This is
from the 2012 NESC which we use certain parts of. (And
looking at the tables the 14ft. seemed the lowest, the other
tables suggested higher clearances. Especially for >300V)

If this is a private line, please disregard the above and
use the NEC's clearances.

My main concern is that we have a city official that
says that a pool needs to be EITHER 10 feet horizontally
OR 22.5 feet vertically, as if there is a choice. As I read it,
both the horizontal and vertical clearance are required.

I think your official has it right. If all of your overhead conductors are outside the horizontal limit, then there is no need to apply a verticall clearance.

In the specific case I am referencing, the lines are less than 10 feet horizontally.
The official is saying that all that needs to be done is move the lines vertically
to 22.5 feet. (The lines would still remain less than 10 feet horizontally.)

That would be compliant. The lines could be directly over the pool if they are 22.5 feel over the pool. Of course one could have a local ordinance that changes things

I'm sorry I did not understand the situation, but
do agree with the 22.5ft. If running along side
of the pool. For something that seems simple, it
can get complicated quickly.

Once again I apologize for not understanding
the conditions.

To whom are you directing this post? What do you not understand?

Dennis, just in general I did not read carefully enough
and that is why I wanted to apologize for the mis-information.
There are two ( or possibly three if local regs. apply ) rules
that could apply and I thought the lines were over the pool
rather than beside it. My mistake.

After checking 680.8 (2014 NEC) this is a case of the 6.9m
(22.5ft) conditions presented it the table. Part C does not
seem to apply (since over 3m/10ft is not met) It seems
the inspector is correct since these are private lines.
Once again I appologize for my error earlier, but was looking
at it from a NESC viewpoint rather than from the NEC.
(Because I didn't know the ownership of these lines.)
