My neighborhood, built from bare dirt about 30 years ago, does, as do the other neighborhoods and commercial sites built here since then.

The answer is always money, though. It's cheaper to put wires up on poles, so that's how it was done. It's expensive to move them underground, so the wires stay up on poles.

Money.

They are safer and less prone to fault underground.

It just costs more.

In Germany: They are in the more urban areas.
The more rural have it either on street poles, poles on the roof, both or underground.

You can do it, but it costs more. I understand that some of the reason that California's electricity rates are as high as they are is because PG&E is doing a bunch of burying lines.

The IOUs spent $7.7 billion in 2024 on wildfire mitigation, which equates to 4.2 ¢/kWh. Due to years of fire suppression, exacerbated by warming trends, and the desire to build homes in wooded areas, wildfires caused by downed distribution lines are a never-ending problem. To resolve the situation, the utilities are burying the power lines, but the cost is enormous.

Wildfire mitigation accounts for just over half of the price premium.

One thing to be aware of is that it's much easier and cheaper to repair damages or upgrade it. Underground is not without problems too, moisture or ground movement for example.

It costs less to maintain poles in high density areas than it would to burry them and have to close off entire neighborhoods.

it's about cost. They're more expensive to bury and to maintain.

And it's not that helpful in storms either because even if the lines near your house are burred, they're still connected to the above ground stuff that runs along roads, rural areas, and the big transmission lines themselves.

Cost. Including maintenance costs.
