Not just Leyland Cypress but also Thuja 'Green Giant' or similar Thuja evergreens (Arborvitae). The cypress and arborvitae get huge, so hopefully that "shrub" is not one of those. By the way, all those trees can be heavily pruned. Electrical companies prune them back constantly to keep them off the lines.
The picture is over a year old and those Green Giant Arborvitae were planted as 8' trees in 2012. Two years later, they are approximately 15' tall and 5' wide, as the picture shows. Today they are almost 20' tall and 6' wide. Next year there will be no spacing at all showing at their base and they will then become the "screen" that I wanted.
