Pretty much. Here is an example of permitting requirements for underground. Underground costs 5-12/foot (or more in urban areas) whereas aerial can be as low as $2/foot.

You have to know everything that's ever been stuffed in the ground within half a mile of where you're working to avoid the inevitable cutting of something important -- gas, water, sewer, power, other telcom, even vacuum tube lines and subways. And then you need trenching gear to get stuff in the ground, and crews to come along behind to remediate the "environmental damage".
