Section 94-64. Criteria and standards for measurement and placement.
(a) Area. The permitted area of ground signs, except in shopping centers or multi-tenant centers, in all zoning districts, and unless otherwise specified in this chapter, is dependent on street frontage of the property on the basis of one square foot of sign area for each lineal foot of property frontage up to the maximum specified in each zoning district. wall signs shall be computed on the basis of one square foot of sign area for each lineal foot of building or tenant space frontage up to the maximum allowed in each zoning section. For the purpose of determining area, the total area of a sign is that within the smallest parallelogram, triangle, circle or semicircle or combinations thereof which will completely enclose the outside perimeter of the overall sign, including the border, if any, but excluding supports. Three dimensional signs shall be measured at the largest vertical cross section.
(b) Combinations of signs. Except where specifically permitted, the types and areas of signs may not be combined to allow a larger size than that listed for a single sign. ground signs may be placed at an angle on a corner at no increase in size over that of a single sign. The sum or the area of the faces visible from any one point shall not exceed that allowed for a single sign.
(c) Corner lots. Where two ground signs are used on a corner lot, the area of both signs may not exceed the area allowed for frontage as provided in subsection (a) of this section.
(d) Display of permit number. The sign permit for all signs requiring a permit shall be prominently displayed by the owner or user of the sign on the property where the sign is located.
(e) Height, setback and location measurements. Measurements for setback and location for all signs in all allowable districts shall be made from that portion of the sign nearest that point of ground reference to which the measurement is to be made, but in no event shall a sign of any kind project over public property or public rights-of-way, whether affixed to a building or otherwise (refer to figure 94-64-1). The height of signs shall be measured from grade level at the edge of the street paving and shall include all decorative portions of the sign. All setback measurements shall be made from the property lines as a point of reference to the projecting edge or corner of the sign, unless otherwise specified.
(g) Size limit. No ground sign shall be supported so that the uppermost edge is more than 30 feet above the grade level from edge of street pavement. This subsection shall not apply to any sign on the face of the building. Any sign that is not attached to a building shall not exceed 150 square feet on its largest front.
