The following principles shall control the computation of Sign
Area:
A. The area of a Sign which has only one face shall be of the entire
Sign Panel and shall be computed by means of the smallest square,
circle, rectangle, triangle, or combination thereof that will encompass
the extreme limits of the Sign Panel.
B. The Sign Area of a Sign with more than one face shall be computed
by adding together the area of all Sign Panels Visible from any one
point. When two identical Sign faces are placed back-to-back so that
both faces cannot be viewed from any point at the same time, and when
such faces are part of the same Sign structure, the Sign Area shall
be computed by the measurement of the larger of the two Sign Panels.
C. The Sign Area of a three-dimensional Sign such as a Trade Figure,
Symbol Sign, or Art Sign shall be computed based on a square, circle,
rectangle, triangle, or combination thereof that will encompass the
largest Visible profile.
All Signs shall be constructed and maintained in accordance
with the following standards:
A. All Signs shall comply with applicable provisions of the state building
code, General Bylaws, and the electrical code of the town at all times.
B. Except for Banners, Flags, Limited Duration Signs, Temporary Signs,
and Window Signs conforming in all respects with the requirements
of this chapter, all Signs shall be constructed of permanent materials
and shall be permanently attached to the ground, a building, or another
