I had the power company come out and mark out their power lines. There is no problem with the 220V lines to my home or the neighbors, as I can miss them, but the fence will need to go over a long stretch of buried high voltage lines.
I contacted the power company after they marked the lines and they are unable/unwilling to provide information about how deep those lines are. I would guess they don't want to say they are three to four foot deep, only to have me found out that they are only two feet deep where I am digging.
The fence is to be about 4 foot tall with an open (about 80% open so minimal wind force issues, but young children may well try to pull them so it does need to be solid.
I was thinking of building a mound of soil giving me more distance from the power lines. However I can see that it might take a year or two for that mound to solidify enough to help support the fence. I was also considering using some sort of concrete, maybe buried in or under the mound.
Just looking for ideas comments and maybe some experiences.
