A detached sign may consist of more than one sign panel provided all such sign panels are attached to one common integrated sign structure. The total area of all such panels shall not exceed the maximum allowable sign area specified for a detached sign on the parcel. Where a sign message consists of separated or individual letters, modules, or symbols, each portion of such sign message shall not be considered as a one-sign panel. In such cases, a single continuous perimeter completely surrounding the sign message shall be utilized to determine its sign area. (Prior code § 3.05.092)
