Purpose. The standards contained herein are intended to:
1. 
Protect the character and desirable living conditions of the town through careful site planning that minimizes the impacts of new construction on environmental features and existing development;
2. 
Encourage site planning and building design that integrates design within the site and establishes a sensitive relationship between the elements of the site plan and contextual features of scenic, environmental or cultural significance;
3. 
Preserve the visual amenity of the town for residents and visitors, especially through the enhancement of building aesthetics; and
4. 
Promote high quality compatible development that reflects the scale and architectural character of southwestern building styles.

A. 
Design standards are listed in STC § 18.82.060. The standards reflect desired goals and policies for the town. Design approval by town staff is required prior to the issuance of a building permit. The standards include Requirements (R), Presumptions (P), and Considerations (C).
1. 
Overcoming a Requirement. There is no administrative process to overcome a requirement. If it cannot be satisfied, an applicant may seek relief through the variance process.
2. 
Overcoming a Presumption. A presumption that may be unsuitable for a given project may be waived if an applicant can demonstrate to the town staff that there is a good reason why the presumption is inappropriate. The town staff may approve an alternative that achieves the intent of the presumption. Appropriate reasons for overcoming a presumption include:
a. 
Demonstrating that in this instance the underlying design principles will not be furthered by the application of the presumption;
b. 
Showing that another design standard is enhanced by not applying the presumption;
c. 
Explaining the unique site factors that make the presumption unworkable.
Increases in the cost of development generally will not be an acceptable reason to waive a standard or determine a standard is inappropriate.
In the event that a presumption is not incorporated or overcome, an appeal may be filed by the applicant with the town council in accordance with STC § 18.82.080.
3. 
Considerations. Inclusion of considerations is encouraged, but omission is not grounds for denying plan approval.
4. 
Town staff may request additional information or require modifications of the proposed design as necessary to perform a complete review and obtain compliance with this section.
