You have major utility lines running across the front of your property at the street. You can not plant trees there. You may plant shrubs. That is the best place to start your decision making process. The one spruce looking tree out there now is already in the wires. Won't be long before it looses the top.

You have a large lawn and plenty of room to plant a shrub border of large shrubs that will get 10-15 feet tall and wide. It will hide the road and done properly will have spring bloom, fall color and berries. Some of the shrubs could even be evergreen, like certain Viburnums.

I understand the power lines are close hence why I said medium size tree. Problem is all the ornamentals don’t have a columnar shape

For sure, nix the pears!! All kinds of issues with them and they can grow tall enough to interfere with overhead wires. If they survive long enough :-)

There are a number of smaller or shorter growing trees that could fit under overhead wires but a columnar or distinctly pyramidal shape might be harder to accomplish. Crabapples, Japanese maples, paperbark maple, serviceberry, hawthorn, dogwoods, redbuds, stewartia, crape myrtle are all possibilities.

If you're trying to gain some privacy from the road, I'd think that you'd want to use some large shrubs at the "end zones" and trees (to maintain view) near the central zone. Are you mainly trying to block the road that is aimed at your house?

Can you give us pictures without the proposed scheme in them?

Yardvaark, exactly what you said. Trying to block the headlights of cars from the end zones and still maintain a view from the middle zone. There has to be a “dwarf” columnar shape tree. I’ll post some pics without the rendering

Second pic is side view starring at busy road before Reno

A whole lot of conifers have a columnar or pyramidal growth habit and they come in a vast range of mature sizes.

And you can find both crabs and Japanese maples that maintain a pretty narrow profile as well. Parrotia persica 'Vanessa' is another possibility, as is Dakota Pinnacle birch.

Really trying to stay away from conifers as I have my entire backyard boxed in white thuja green giants. Wanted something to look more country.. limbs and branches etc

Gardengal48 just checked out that Dakota pinnacle birch. That’s beautiful

And it has the bonus of being very resistant to bronze birch borer!!

How many feet set back from the curb are the overhead wires?

If the view where you've pasted 6 trees marching across the lawn is the pertinent point of view, I can't see how you're going to achieve a good result with the scheme shown (in now the 3rd picture from top.) To block the road, the limbs of the trees would need to be left hanging so low, that they'd look unkempt. Eventually, as the trees gained size, they'd need to be limbed up so as to keep from encroaching into the road. If the overhead wires limit the space as much as it appears, the trees could not grow very tall.

The bottom of the utility lines don't look more than 20 feet high to me gauging by the conifer already growing into them.

It would make more sense to place the fence at the proper in set from the road and plant any trees inside the fence. Not only should you not plant trees under the wires, you should not be planting them on the DOT's right of way for the road.

If you can manage to plant the trees at least fifteen feet away from the center line of the wires you will have a lot more options for your columnar tree preference and everything else you want to accomplish screening wise.

Chris and yardvaark,
With my current situation I know I am not going to achieve total privacy and that’s okay. I’m not trying to hide my house but rather trying to soften up if you will.

I like the uniformity and clean lines of columnar trees. I could also crown the tops before they become to close to power lines if I had too however that is what I am here for advice. Looking for ideas for trees that fit my design criteria that hopefully won’t be a problem in the future as far as maintenance.

Thanks guys

I'm seeing something along these lines as being more realistic ... where the tree forms are in your yard, not under the wires, and where shrub forms are used to screen what is behind the ends of the scene. I'm using multi-trunk tree forms because they screen more at lower levels. They should be small unless you're looking to produce lots of shade on the lawn -- my picture representing, more or less, a mature height. (The scheme would need to be worked out in plan view. We don't have that or a complete view of the area.)
