16.10.030 Commercial Districts Design Standards.
   The following standards and design features are provided to ensure a level of quality that must be compiled with or satisfied in all commercial developments. Standards are mandatory requirements for all commercial developments. Design features are provided to allow flexibility by providing options for implementing specific standards. In order to meet a certain standard, one or a combination of design features shall be incorporated in the project’s design. In some instances, there will be no design feature(s) identified for a particular standard.
   A.   Site Planning.
      1.    Site Character.
         a.   Standard. Natural amenities (e.g., views, mature trees, creeks, riparian corridors, and topographic features) unique to the site shall be preserved and incorporated into the project's design whenever possible.
         b.    Standard: Structures that are historic or are otherwise distinctive because of their ruralness, age, cultural significance, or unique architectural style as determined by the council shall be preserved and incorporated into development proposals.
         c.    Standard: Structures shall not face their back side or loading areas onto existing or planned amenties (e.g. parks, open space, and water features).
         d.   Standard: Frontage roads or drives shall be provided adjacent to open space areas unless the commercial project is designed to provide direct pedestrian access to the open space and the road or drive is not otherwise necessary.
         e.   Standard: Development on sloped properties shall generally follow the natural contours of the land by use of at least one of the following design features:
            1)    Use terraced parking lots.
            2)   Provide stepped building foundations and retaining walls.
            3)   Incorporate larger setbacks to preserve natural landforms.
      2.    Land Use Buffering.

         b.   Standard: Loading areas, access and circulation driveways, trash. storage areas, and mechanical related to commercial uses equipment related to commercial use shall be located as far as possible from adjacent residences.
         c.   Standard: When adjoining residential and commercial uses can mutually benefit from connection rather than separation, appropriate connective elements (e.g., walkways, common landscape areas, building orientation, and unfenced property lines) shall be provided between the uses.
         d.   Standard: Window orientation in nonresidential buildings shall preclude a direct line of sight into adjacent residential units and private open spaces within one hundred (100) feet of the property line.
         e.   Standard: When commercial buildings back up to open space areas of multi-family residential projects, the rear setback area shall be landscaped and combined with the residential open space where feasible.
         f.   Standard: Evergreen trees shall be planted a minimum of thirty (30) feet on center, and may be required to be planted closer, depending on species. to screen parking lots and large commercial building walls in order to provide a visual barrier between commercial and residential uses.
      3.   Building Placement.
         a.   Standard: On multi-tenant commercial sites, a minimum of fifteen (I 5) percent of the total building frontage shall be located at the front setback line. The Director may waive or reduce this standard for projects where implementation of this standard may not be feasible.
         b.   Standard: Corner buildings shall provide a strong tie to the setback lines of each street. The primary mass of the building shall not be placed at an angle to the corner. This does not preclude angled or sculpted building corners, or an open plaza at the corner.
         c.   Standard: Multiple buildings in a single project shall provide a functional relationship with one another to achieve a `"village" scale by use of at least two of the following design features:
            1)   Cluster buildings around open plaza areas, not parking lots.
            2)   Provide courtyards with landscaping and other pedestrian amenities.
            3)   Provide convenient pedestrian circulation between buildings and between parking areas and buildings using enhanced paving materials.
            4)   Link building together visually using trellis structures, arcades, and enhanced paving.
            5)   Avoid dated L-shaped shopping centers with parking located adjacent to the street.

         e.   Standard: Loading facilities shall be fully screened from view from all adjacent public streets and freeways. Screening shall be accomplished with architectural elements or landscaping or a combination of both. Screening shall be provided to adequately screen or soften view of loading areas, trucks, trash enclosures, and similar service facilities from adjacent public roadways.

      3.   Site Access.
         a.   Standard: Developments with more than one hundred (100) parking stalls that are located on an arterial or larger road shall coordinate access points with median openings and existing driveways on the opposite side of the roadway. Final locations shall be subject to review and approval by the city

            1)    Parapets concealing flat roofs and rooftop equipment. The average height of a parapet shall not exceed fifteen (15) percent of the height of the supporting wall and parapets shall not at any point exceed one-third of the height of the supporting wall. Parapets shall incorporate a three-dimensional cornice.
            2)   Overhanging eaves, extending at least three feet past the supporting walls.
            3)   Sloping roofs that do not exceed the average height of the supporting walls, with an average slope greater than or equal to one foot for vertical rise for every three feet of horizontal run and less than or equal to one foot of vertical rise for every one foot of horizontal run.

         b.   Standard: Parapet walls shall be treated as an integral part of the structure design.
         c.   Standard: Parapet walls should receive architectural detailing consistent with the rest of the facade design and should not appear as unrelated elements intended only to screen the roof behind.
         d.   Standard: Where a mansard roof is incorporated into the parapet design, views from above the structure should also be considered relative to any visible structural support elements.
      5.   Building Materials.
         a.   Standard: False or decorative facade treatments, wherein one or more unrelated materials appear "stuck on" a building, shall be avoided.
         b.   Standard: Fake products that attempt to imitate real materials (e.g., wood, stone, brick, etc.) are not allowed.
         c.   Standard: The composition of materials shall avoid giving the impression of thinness and artificiality.

         b.   Standard: Building trim and accent areas may feature brighter colors, including primary colors, but neon tubing shall not be an acceptable feature for building trim or accent areas except for movie theaters.
         c.   Standard: The transition between base and accent colors shall relate to changes in building materials or the change of building surface planes. Colors should not meet or change without some physical change or definition to the surface plane.
      7.   Additions to Existing Structures.
         a.   Standard: The design of an addition to an existing structure shall follow the general scale, proportion, massing, and detailing of the original structure. The addition shall be harmonious with the original structure, not a stark contrast.
         b.   Standard: Additions shall be an interpretation of the existing building wherein the main characteristics of the existing structure are incorporated into the design of the addition by use of at least two of the following design features:
            Parameters:
            1)   Repeat window and door spacing;
            2)   Use harmonizing colors and materials; and
            3)   Include similar, yet distinct, architectural details (e.g., window/door trim, lighting fixtures, tile/brick decoration, etc.).
