I was told by Comcast that there is a law
Politely ask Comcast to produce a copy of the law. They can tell you anything they want, but that doesn't mean that they have an accurate understanding of it. Have you looked at the plat for your property to see if an easement is noted on your property? If not, get down to the courthouse and check it out. The plat of my property and neigborhood, shows the exact placement of easememts. In my case, there is a fifteen foot easement across the rear of my property for local utilities. All electrical, cable, natural gas, sewer, and telephone run behind my house and my neighbors. There is both aerial and buried in this easement. I own the property, but the utilities have the right to use it for their purposes. Go check out your situation.
Around 1990, the cable co. illegally installed cable on my property. The family owns part of a private road that runs along side our house and that is where all the utility lines are. The family got a contract from the cable co. that states we are to receive "free cable services for life."
Sounds like you entered into a contract with the cable company to me, which might not rise to the level of illegal. Does the cable company provide services to other customers from cable along the route that you provided? Do all of the utilities provide services using this route?
If the power company places their lines underground, the family is worried what will happen with the cable co. contract.
That issue seems to be seperate from your question regarding easement rights. Is the cable company proposing to reroute their cable to another location or what? Explain.
We have very little problem allowing the power company permission so long as the cable co. still honors the contract of "free cable services for life".
Then work a new deal with the cable company to continue to provide free service. If I were the cable company it wouldn't take me too long to come to the conclusion that providng free cable service would be cheaper than a lawsuit. If you go this route, have an attorney draw up the contract for you.
Again, head on down to the courthouse and check out what type of easeent is recorded on your property. If you don't understand it, make an appointment with a local real estate attorney and have them explain it to you.
