(A) Sign illumination. Except for billboards, all sign illumination shall be from the interior or from floodlight projection, shielded to preclude glare visible from public rights-of-way and neighboring properties.
(B) Rotating signs. Rotating signs are permitted, provided that the outer edge shall not exceed a speed of four revolutions per minute, and the rotating portion of the sign shall be a minimum of ten feet above the adjacent grade. No rotating sign shall extend over public right-of-way.
(C) Roof-mounted signs. Signs projecting above the point of intersection of the exterior wall of the building with its roof shall be mounted on a parapet, or within the same plane as such exterior wall. Sign area for roof-mounted signs shall be calculated the same as, and counted as part of the facade signs. Roof-mounted signs shall be allowed only within commercial and commercial retail areas.
(D) Measurement of sign area. The square footage of a sign, made up of letters, words or symbols within a frame, shall be determined from the outside edge of the frame itself. The square footage of a sign composed of only letters, words or symbols shall be determined from imaginary straight lines drawn around the entire copy or grouping of such letters, words or symbols. Double-faced signs shall be calculated as the area of one side only. Three-dimensional or multi-faced signs shall be calculated as the maximum area visible from any single direction at any point in time.
(E) Measurement of freestanding sign height. The height of a freestanding sign shall be measured from the elevation of the crown of the nearest public street to the highest point of the freestanding sign or its supporting structure.
(F) Condition and maintenance. All signs shall be of rust-inhibitive material, or treatment, and shall be maintained in good condition in the opinion of the code official. All signs, together with all of their supports braces, guys and anchors, shall be kept in good repair and in a safe state of preservation. The display surfaces of all signs shall be kept neatly painted or posted at all times.
