In addition to the applicable district regulations in C1-8, C1-9, C2-7, C2-8 and C4-6 Districts and C1 or C2 Districts mapped within R9 or R10 Districts, all signs, other than advertising signs and window signs, shall be located in a horizontal band not higher than three feet, the base of which is located not higher than 17 feet above curb level. Where there is a grade change of at least 1.5 feet in 100 along the portion of the street upon which the development fronts, such signage band may be staggered along such street.

When a building on a contiguous lot or contiguous block contains accessory business signs within a coordinated horizontal band along its street frontage, the signage strip along the development shall be located at the same elevation as the adjacent band, but in no event higher than 17 feet above curb level. Where coordinated horizontal bands exist on two contiguous lots or contiguous blocks on both sides of the development, the signage strip shall be located at the same elevation as one adjacent band, or between the elevations of the two. For the purpose of this Section, the elevation is measured from the curb level to the base of the signage strip.
