In order for a sign to be effective, it first needs to be seen. Even before color, lighting, and other design considerations, a direct line of sight to the viewer must be assured. When signs are too low to the ground, they often are blocked by other objects, like cars, pedestrians, and landscaping. This interrupts that direct line of sight.
In situations where low signs are required, special care must be taken to place those signs in best position to be seen by potential viewers. A focus on setback location, landscaping, and placement of information on the sign face can maximize the effectiveness of a sign that has been impeded by a restrictive code.
