I'm in the county in Washington State.
As some here know I have been unsuccessful in getting Comcast to run 500' from the pole to the rent home I have...
Also, the direct bury electric cable installed by the utility has been repaired twice at no charge by the utility and I have been told it is at the end of its useful life and they no longer direct bury and require the owner to provide conduit.
Third... I've been thinking it might be nice to have a camera/intercom and a hose bib at the start of the driveway.
Comcast is supposed to be sending the requirements and a sketch... from what I can tell they really only care that I install 2" conduit.
Thinking about doing my own trenching and would like to kill all birds with one trench/excavation...
The previous owner told me they had trouble with a trench that went straight to the house channeling water and suggested I not go down the driveway and instead go down the property line and make a 90 sweep to the house with a concrete vault because water doesn't flow uphill...
I realize utilities often don't play nice when it comes to sharing... on the other hand adding a couple of empty conduits seems like a win/win for me even.
There are code considerations for running low voltage and high voltage in the same trench. It's been a while, but IIRC it's a separation issue. Yes, your buried power line should be in conduit. I installed one in the late '70s and never considered not putting it in conduit. You can only fill the conduit so full with power cable, so you probably will need 3" or 4" for the power company. For the phone company I would suggest installing your own wire and using the best direct burial twisted pair you can buy. You definitely need a couple concrete water stops in the trench to keep surface water from following the conduit.
