(a) Purpose. Buchanan Street between Post Street and Sutter Street is a pedestrian-only thoroughfare lined with both neighborhood- and regional-serving retail uses. This block of Buchanan Street contains seating areas and culturally significant street furnishings, such as lighting and fountains. As such, it is important to allow for appropriate development heights while also maximizing light and air to the street.
(b) Controls. Along Buchanan Street between Post Street and Sutter Street, the portion of any building above 35 feet in height shall be set back one foot in height from the front property line for every foot above 35 feet, except for those exemptions listed in Section 260(b) of this Code.
