A. Building design. The following design and development standards shall apply to all development that occurs or is proposed in the WX district:

1. Multiple buildings on a single site shall be designed to create a strong visual relationship between or among the buildings. Architectural treatment of a building shall be consistent on all sides.

2. Development shall take into account the relationship of adjacent buildings in terms of height, materials, scale and architecture. The goal is to achieve attractive structures and preserve significant views.

3. Mixed-use developments shall be encouraged to provide increased opportunities for informal and planned activities beyond the typical 9:00 a.m. to 5:00 p.m. work hours, including secure, well-lighted amenity zones and programmed activities. In addition, design that will increase opportunities for activities both within the project boundaries and between existing adjacent developments and neighborhoods shall be promoted.

4. Interest shall be created by both the repetition and changes in various patterns from window openings to paving designs. Developers shall consider the use of decorative pavement accents in sidewalks and near street intersections.

5. When a project occurs in a visually rich context, such as the waterfront, its form, materials, orientation, and detailing shall incorporate the assets offered by its setting.

6. The size, character and siting of proposed projects shall relate to the functions of adjacent streets and pedestrian networks. Buildings shall be oriented to the public rights-of-way and shall be placed close to pedestrian movement.

7. Environments shall be created that encourage a number of specific activities to front a street, court or plaza at ground level to provide variety at a human scale.

8. Where feasible, the design of multi-use facilities to accommodate retail and other uses at the pedestrian level that increase activity and use shall be encouraged.

9. Buildings shall be designed and located to complement and preserve existing buildings, streets and paths, bridges and other elements of the built environment.

10. Buildings shall be designed to be complementary in appearance to adjacent structures of good design with regard to:

a. Materials, color and texture;

b. Setbacks;

c. Roof lines;

d. Height; and

e. Overall proportions.

11. Where existing buildings are to remain on site, new development shall be designed to:

a. Integrate the remaining buildings into the overall design; or

b. Provide separate landscaping, remodeling or other treatment that establishes a distinct character and function for the remaining buildings.

c. Existing pedestrian paths or public areas shall be retained whenever feasible.

12. Bus shelters, drinking fountains, benches, mail boxes and related amenities shall be designed to be complementary in appearance to buildings.

13. The following amenities shall be designed to be complementary in appearance to those buildings or structures upon which they are located: windows, doors, mailboxes, mechanical equipment, downspouts, utility connections and meters, chimneys, lights, signs, awnings, foundations, vents, stairs, decks and railings, weather vanes, aerials and other appendages attached to the roof or projecting above the roofline.

14. Awnings, signs and lights shall be placed at the specific location on the wall to define the first floor or retail cornice height.

15. Trees and other natural elements shall be used to help define building proportion relationships and to provide scale to the structure as a whole.

16. Thematic consistency shall be encouraged and the variety of styles of building elements shall be minimized while allowing a diversity of architecture.

17. Buildings shall be designed and located to complement and preserve existing natural landforms.

18. To the extent practicable, landforms shall be incorporated as design elements that relate to building elevations to determine scale and proportion.

19. Foundations shall be designed to match the scale of the building being supported. Use of berms, re-siding, or sheathing the foundation structure with wall siding are methods that accomplish this purpose.

20. Decks, railings and stairs that relate a building to the contours of the land shall be used.

21. Buildings shall be designed to minimize the personal security risks of users and to minimize the opportunities for vandalism and theft.

22. Buildings shall be designed and constructed to reduce noise impacts on interior occupied spaces and adjacent property.

23. Natural barriers shall be used where possible, and where it is not possible, the use of solid barriers such as fences, berms, or structures to reduce sound levels shall be considered.

24. Heat pumps or similar mechanical equipment shall be located so that operating noise does not affect use of living areas such as bedrooms, outdoor decks, patio areas of the use or adjacent uses.

B. Building scale/transition.

1. A large structure shall contain design elements that create a transition to the human scale, particularly near the ground.

2. If a development is larger or smaller than surrounding uses, the design shall provide transitional elements at the perimeter to integrate it with its surroundings.

3. Transition using variety of scale, pattern and texture of building and landscaping elements is encouraged to create a more visually interesting project.

4. Buildings shall be designed to reveal or express their primary patterns of use and entry.

5. The proposed building orientation shall respect the orientation of surrounding buildings and streets and shall relate to other buildings on the same site in regard to pedestrian circulation.

6. Buildings shall be designed and located to complement and preserve existing natural landforms, trees, shrubs and other natural vegetation, where appropriate.

7. A balance in the height, bulk and scale of the buildings constructed within the site shall be achieved so that large and/or long blank walls are either not constructed or their features are minimized. These standards can be achieved by the use of certain landscape features, specific building materials, limited size and length of buildings, preserving significant existing trees, screening mechanical equipment, innovative signage, limiting or prohibiting structures within side building setbacks, limited fences and/or hedges within view corridors, and visual penetration through structures.

C. Building heights/views.

1. Views from the residential areas above the river to the river shall be protected to the greatest extent practicable.

2. Views within the waterfront property to the river shall be protected to the greatest extent practicable. Access to views of both the project’s users and the general public shall be considered.

3. Major views and view corridors that give special emphasis to open space, the river, and special man-made or natural landmarks shall be protected to the greatest extent practicable.

4. Buildings shall be located and designed to provide access to desirable views, while not blocking the views of others unnecessarily.

D. View analysis. As part of the master development plan, an analysis of views from the residential area above the site including view corridors, view profiles and vertical profiles from various locations is required. The views and/or view corridors to be protected are perpendicular and at angles to the river and include those views from the residential area above to the river and those seen from within the site to the river.
