Mass, scale and architecture which is compatible with existing and adjacent neighborhoods. The intent is to encourage appropriate transitions between uses and structures of varying residential density and a general compatibility of architectural styles. |
|
|
Original designs that are tailored to the site and discourage monotonous or institutional type buildings and site design. |
|
|
Site designs that preserve, enhance and incorporate the significant natural features of a site as an element within the overall design. |
|
|
High quality building designs that consist of durable and maintainable materials for the exterior treatment of the buildings that complement the building mass and articulation. |
|
|
The establishment of a streetscape presence and appearance through setbacks, landscaping, building placement, and architecture that defines the pedestrian and vehicular corridor and presents an appealing and continuous theme along a sidewalk, street or trail. |
|
|
Landscaping that softens the appearance of pavement and structures, and provides an eventual tree canopy along the street and pedestrian walkways. |
|
|
Ensure that design provisions do not preclude the development of multifamily housing affordable to all income levels. |
