Wall signs shall be placed within an information bank immediately above the storefront. Wall signs shall not project more than 15 inches from the building surface, and shall not have an aggregate area of more than one square foot for each linear foot of building face parallel to the street lot line, or 10% of the wall area to which it is attached, whichever is less. No part of the sign shall be higher than 15 feet above the second floor window sill, parapet, eave, or building facade. Where more than one sign is attached to the same wall, the sum of the area of all of the signs shall not exceed the total sign size permitted per wall face.
