huggy, Bayberry is evergreen where you live, grows fast, native in your area, can take a trimming too, Arborviates are wonderful, they take a trimming, but buy at least 6 ft, they grow slow. Other shrubs were mentioned too, look up online, and go visit a privately owned nursery and ask them, they will know what you should plant there, I would go with ever green though. That view would drive me crazy. You have absolutely no privacy at all, how can you enjoy your yard? Good Luck.

Without a photo I am having a difficult time understanding why privacy is needed at the front end of your driveway which presumably leads to the public street? One would think privacy activities take place in the back yard. That said it is your right to want it :) But eighteen inches of width and a desired height of eight feet that behaves and stays that size is a tall order- it would be my opinion that anything you do is going to require more maintenance than it is worth unless pruning is your favorite hobby. I don't think DeGroot's would be good for privacy as they are so narrow toward the top. I have three in a group and while they are one of the best looking arborvitaes I have their use is more architectural than screening. Mine have gone from a couple of feet to approximately six/seven feet in five years. How long are you willing to wait? And I have to say that the thought of pruning a plant as naturally perfect in form as a DeGroot's makes me a little ill. Again, without a photo it is difficult to say but I would plant something thick and screening down as far as was practical and then use decorative boulders in the narrowest section. Or surprise my wonderful neighbor with some plants that he could plant on his side of the fence. Maybe a neighborly discussion is in order?

radock03, A few questions first. How long and wide an area are we talking about? What's your soil type and elevation? Other than screening, what do you want the plants do (edible fruit, wildlife habitat, etc.)? Are you looking for strictly evergreen/conifer or would a mix with deciduous plants be ok? Will you be able to water the trees/shrubs at planting and once a week during the growing season till established, which might be a year or longer? Would you be able to water the new plantings during a dry winter? Not an issue this year, but in the future it might be. Fast growing usually equals weak-wooded, which might be an issue if this is an open, windy area. Wind and heavy snow can damage plants, particularly fast growing plants. I'd steer clear of a monoculture (all one plant type). If water access is an issue, it will limit your selections. Sorry for the multiple questions. I don't want to start making suggestions till I know a bit more about your goals. If you're ok with starting with small plants, CSU recently sent out their tree order forms. This would be a great opportunity to try out some native plants and you could get 25 - 50 seedlings for the price of one tree at your local nursery. They also have one gallon trees for $9. I'll include links below with the order form, current available inventory and a link to your local conservation district. CSU will ship the trees to you, or you can get an order form from the El Paso/Woodland Park District and pick up trees from their location. CSU Tree Order info. Updated inventory list El Paso County Conservation District If you are looking for larger plants, more instant gratification, the info above might not interest you, but I thought it would be a good starting point.

Do you have space for a tree, both in the yard and overhead with regard to wires? That is a really skinny space to grow anything with height, and it will most likely damage the fence over time as well as have potential root problems from having such a limited root run. You aren’t the only one having problems with posting photos in the original comment. Houzz messed with the programming a few weeks ago and posting photos to the initial comment is now exceedingly slow and often unreliable. But they do post well in the follow up comments.
