2. For buildings more than one story in height, the combined wall sign area shall not exceed that permitted for a single story by more than ten percent for each additional story. In no event, shall the combined wall sign area exceed by 50 percent that area permitted for a single-story building.
3. For wall signs that are made up of individual letters that use the wall of the building as background, the allowable sign area may be increased by 20 percent, provided there is no change in color between the background and the surrounding wall area.
4. The combined sign area of illuminated architectural canopy signs, roof signs and wall signs facing the same direction shall not exceed two square feet for each foot of street frontage, plus one square foot for each foot of building frontage.

B. Height. A wall sign shall not extend above the top of the wall of the building.
EXCEPTION: Where there is less than three feet between the top of the wall and the top of a window, the wall sign may extend above the top of the wall by a maximum of three feet.

Identification signs shall comprise no more than 80 percent of the width of that portion of the building where the signs are attached.

F. Parking Lots. Where a parking lot exists between a wall sign and the street, and there is a wall between the parking lot and the street, a portion of the total sign area permitted by this section may be used on the wall located between the parking lot and the street so long as the sign does not project beyond the lot line. The sign shall be restricted to that portion of the wall between two feet six inches and three feet six inches in height above the finished grade at the base of the wall generally facing the street.
