Answer: The only tall privacy screen type plant I can think of that will fit in the site you describe is Thuja (arborvitae). Thuja occidentalis has an upright, open growth pattern, eventually reaching about 30' tall and 2'-3' wide at the base. Thuja plicata, or Western Red Cedar, can reach 30'-50' tall. It has a very dense, narrow, erect growth habit and can be sheared to maintain a width of about 4'. Hope these suggestions help you choose just the right plant.
