The intent of this division is to control all signs within the Town, to ensure that they are appropriate for their respective principal uses and in keeping with the appearance of the affected property and surrounding environment, and to protect the public health, safety, morals and general welfare. In addition, the intent of this article is to:

A.

Encourage good design in the context of the overall image and visual environment of the Town;

B.

Protect property values; enhance the appearance of the business and industrial community;

C.

Stimulate the economic vitality of the Town, encourage a business atmosphere that continues to attract new enterprises to the Town, encourage trade within the Town, and to appropriately inform consumers;

G.

Avoid excessive competition for placement of signs, so that permitted signs provide identification, direction, information and advertising while minimizing clutter and unsightliness.

2.

A sign placed on land or on a building for the purpose of identification, protection, or directing persons to a use conducted therein shall be deemed to be an integral but accessory and subordinate part of the principal use of land or building. Therefore, the intent of this article is to establish limitations on signs in order to ensure they are appropriate to the land, building, or use to which they are appurtenant and are adequate for their intended purpose while balancing the individual and community interests.

These regulations are intended to promote signs that are compatible with the use of the property to which they are appurtenant, landscape and architecture of surrounding buildings, are legible, are not distracting to motorists, and are constructed and maintained in a structurally sound and attractive condition.
