I was driving through the old part of town, yesterday.
All of their utilities (that can be) are overhead
(ours are below grade).

A couple of things that stood out:

- the larger "telephone poles" (e.g., for the main high-tension,
cross-town feeders) are metal (multisided tapered extrusions
instead of "cylindrical tubes" (the legacy poles are wooden)
- some (older) of these are set directly *in* the ground
- others are bolted, flush, to a footing of sorts that is set
in the ground. Likely to leverage the cost of the footing
(if the pole needs to be replaced)
- the newest are similarly bolted to a footing... but, the
(large) bolts act as little legs holding the base of the
pole ABOVE the top of the footing, by a few inches (e.g.,
one could slip their arm UNDER the bottom of the pole)

I assume this to be a revision of the "bolted flush" approach.
Using the bolts as legs allows them to be tweeked to ensure the
pole sits at a true vertical. And, provides a sacrificial
member that allows the footing to be preserved in the event of a
catastrophic collision with the pole (which would likely
compromise the pole... AND, the footing if it was "bolted flush")

- there's a lot of surplus wire flying with the main cables
- some are obviously service loops; particularly those that
double back on themselves in the vicinity of splices (telco?)
- others just look like someone decided to store the balance of
a roll of cable up where no one can get at it!

These don't look like planning for expansion as the areas where
I encountered these are already built up. (and, if PSTN, then
it's largely obsolescent, though some may be CATV -- but, usually,
a distribution amp is visible proximate)

They are too long to be considered convenient "pigtails" to
probe the cables they're spliced into "from the ground".

And, there are other cases where braided steel cables are
similarly "stored".

It's hard to get a good look at these things when driving...

Anyone have an explanation for these?

This has to be an evolved practice...

Bolted flush:

"On stilts":

If you "step back" (zoom out), you can get an idea for sizes.

And, you can "drive around" to notice how none of these approaches are
universally used -- the "next pole" can be entirely different!

For example:
<https://www.google.com/maps/@32.2495865,-110.9568033,3a,75y,143.36h,95.59t/data=!3m6!1e1!3m4!1szOgx279HZe0BDCpY8VqnhQ!2e0!7i16384!8i8192?entry=ttu>

and the pole immediately north of it:
<https://www.google.com/maps/@32.2500019,-110.9569357,3a,75y,52.63h,99.64t/data=!3m6!1e1!3m4!1sBlI9rgoVE_B3V6g1XkxaQg!2e0!7i16384!8i8192?entry=ttu>

and west of it:
<https://www.google.com/maps/@32.249797,-110.9577687,3a,75y,195.42h,101.14t/data=!3m6!1e1!3m4!1sG0bQwO4vWtelUNgbpstw1A!2e0!7i16384!8i8192?entry=ttu>

and south of it:
<https://www.google.com/maps/@32.2488758,-110.9568536,3a,75y,192.05h,97.37t/data=!3m6!1e1!3m4!1s-JayGJs1kIjzxlngV_gCeg!2e0!7i16384!8i8192?entry=ttu>

Here's an example of the "braided steel cable" I mentioned:

<https://www.google.com/maps/@32.2646933,-110.9722007,3a,75y,161.17h,102.92t/data=!3m6!1e1!3m4!1smTiSOqqkaeygPP21luzYzQ!2e0!7i16384!8i8192?entry=ttu>

<https://www.google.com/maps/@32.2643204,-110.972124,3a,15y,332.48h,93.91t/data=!3m6!1e1!3m4!1sP8GPPZbhEObNdifiZZHA-A!2e0!7i13312!8i6656?entry=ttu>

(you may have to navigate around the pole to get a better view of it
and how it ties in to the cables, there)

And the soil built up around those that *appear* to go straight into
the ground?

you can pour the foundation so it is slightly below ground level

It's not to save the footing. It's to save the person who impacts the pole.. The idea is the pole will give way, reducing the impact on the car or truck.

"Obsolescent" is an interesting word. More appropriate would be "deprecated", I think. Obsolescent would imply they are being replaced, because there is something better. But deprecated does not carry that baggage. There is nothing wrong with older technology. The city I grew up in used pairs to run every phone line in the city, along with a bunch of spares for growth.. But the growth came in ways they didn't expect, with many homes wanting multiple phone lines.

At my house they added "pair gain amplifiers" in the '70s. Strange name, but it is just a digital encoder, able to carry some multiple lines over three pairs, hence "amplifier" in the name. It's vaguely like a T1, but will work on lines that are lower quality. As far as I know, this equipment is all still in use. No one is going to replace the many miles of copper pairs with fiber optics, even though this is very, very out of date. It's deprecated, but not obsolescent.

What incentive, that? Fill the void *under* the pole and then
on top of the base?

A more likely explanation is that they are either flush mounted to a
footing or sunk directly into soil.

We have:
- "telephone poles" (wooden, not possible to "bolt" them to anything axially)
- light poles
- (overhead) sign poles
- the various varieties of poles I illustrated

I'd wager light poles and sign poles are bolted, flush, to a base footer.
Note that he pole can be made such that its base is normal to the central
axis of the pole. And, you can surely pour a flat (normal to the gravitational
field) slab of concrete -- all of our homes are built on such.

Only the "largest" (for some definition of "large" that doesn't directly
correlate to diameter or height) of the poles that I've found use the
"stilts" approach in a verifiable manner. Note, also, that the bolts connect
to another *metal* plate that is (somehow) connected to the ground -- likely
driven deep below grade (*possibly* anchored in concrete)

<https://www.google.com/maps/@32.2502656,-110.9721892,3a,15y,169.8h,82.9t/data=!3m6!1e1!3m4!1sWkIYLsLdwHXIr_kOmkgLCQ!2e0!7i16384!8i8192?entry=ttu>

Note that any concrete beneath the soil surface would have to be
either only slightly wider than the metal base *or* sufficiently
below to allow e.g., the electrical conduits to enter the soil
and attain a sufficient level beneath the surface to not be
vulnerable to disruption from superficial excavation.

Note the light pole adjacent:
<https://www.google.com/maps/@32.2508152,-110.9720125,3a,37.5y,237.48h,85.16t/data=!3m6!1e1!3m4!1s58UN5Us2jMNjUSR-Ipz52g!2e0!7i16384!8i8192?entry=ttu>

Large PV arrays seem to anchor their supports directly in the ground:
<https://www.google.com/maps/@32.2502766,-110.8392608,3a,15y,100.32h,78.96t/data=!3m6!1e1!3m4!1soCsiVDqetrnacXRowOJqXg!2e0!7i16384!8i8192?entry=ttu>
(I'd imagine this structure sees more of a static load -- panels -- and
dynamic load -- wind sail -- than a light pole or power pole.)

Note that hitting *any* of these "ground anchored" structures is likely
a fatal experience at any significant speed:
<https://www.kold.com/2021/12/27/traffic-alert-tpd-investigating-vehicle-collision-involving-pole-prince-campbell/>
And here's the pole in question:
<https://www.google.com/maps/@32.2709959,-110.9438727,3a,15y,346.32h,91.5t/data=!3m6!1e1!3m4!1ssuw-w7XnWhjcI4GJXGWaCw!2e0!7i16384!8i8192?entry=ttu>

(gotta wonder how they hit it coming from THAT direction at enough speed
to have done that much damage -- it's a frigging DRIVEWAY!!)

Perhaps to make a safe area for pedestrians right up to the pole.
