Notwithstanding the above, in a building on a corner lot, parking is permitted in the front portion of the first floor (or basement not entirely below ground) facing the street with the lower traffic function. Along the street frontage, such parking shall be concealed with facade materials comparable to those used on the remainder of the building. To the extent practical, eye-level fenestration with translucent, but not transparent, glass shall be provided, or the portion of the building devoted to parking shall be screened with evergreen plantings.
