19.23.090 Sign illumination.

Permitted methods of illumination may be divided into several types as described below. All signs shall be engineered in compliance with applicable portions of the building and electrical codes. All electrical service to ground mounted signs shall be placed underground. Electrical service to all signs shall be concealed from public view.

(A) Indirect Illumination. The sign has neither an internal light nor an external source, which is intended to specifically light that sign. Rather, the sign depends on the general lighting of the area (e.g., parking lot, traffic or pedestrian areas) for illumination.

(B) Internal Message. The sign face is made of metal, wood or other material that is not translucent, and the message is cut out of the material and replaced with a translucent material. The sign's light source is located inside the sign.

(C) Externally Lit Signs. Spotlights specifically directed at it lights the sign. The spotlights shall be fully shielded so that they are not visible from roads or adjoining property.

(D) Internally Illuminated Channel Letter Sign. Individual letter or figures affixed to a building or freestanding sign structure with the illumination source covered by a translucent material.
