8.4 Design Considerations
As used in this Section of the Regulations:
- The word "shall" means that the relevant consideration, standard, criterion or action will be applied unless the applicant demonstrates that it would clearly be unreasonable or undesirable to do so.
- The word "should" means that the relevant consideration, standard, criterion or action will generally be applied, but the applicant may offer, and the Commission may approve, an alternative if the Commission finds that the alternative would better fulfill the overall goals set forth in these standards.
Since the architectural design, scale and mass of the buildings and other structures are important in determining the visual character of an area, the considerations listed in this Section are recommended in certain areas (such as the Waterfront Business Residence District and the Five Corners District) so as to ensure that new buildings harmonize with and will be compatible with the neighborhood, to protect property values and to preserve and improve the appearance and the beauty of the community.
- The design considerations listed in this Section are intended to aid in maintaining and enhancing the character and quality of the buildings and public spaces in designated areas in Groton (such as the Waterfront Business Residence District and the Five Corners District) in order to maintain and enhance:
- The distinctive character, landscape and historic value, especially in areas designated as "village districts";
- The sensitive balance of visual and spatial relationships that create the character and support the function of the designated areas;
- The overall quality of the built environment; and
- The economic and social vitality of areas which depends upon maintaining the attractiveness of the street environment, the economic viability of businesses, and a hospitable atmosphere for residential occupants and visitors.
- These design considerations may also be used as part of development reviews in other areas of Groton, particularly as part of the Special Permit process.

8.4.D Building Design
Architectural designs appropriate to a New England community are generally preferred (pitched roof buildings, colonial facades, etc.).
