1234.10 DESIGN STANDARDS AND PRINCIPLES.
   All new development or redevelopment projects in the CM District shall  be subject to the following design standards and principles.
   A.   Consistency with Transit Oriented Development (TOD) Plans.  Where  a TOD plan has been adopted by the City, the arrangement of land uses, public open spaces and streets should be consistent with the intent of that plan.
   B.   Building and Site Design.
      1.   Buildings and sites are encouraged to accommodate a mixture of uses permitted in this district. A mixture of uses is encouraged not just within the overall district, but on individual parcels and within individual buildings. High activity uses such as retail are encouraged on the first floor, with uses such as offices and residential encouraged on second floors.
      2.   Buildings shall be designed to respect the street context, to form street walls where appropriate, and to respect or create view corridors.
      3.   Buildings and sites shall be designed to emphasize pedestrian scale, human scale architecture, and landscaping, while avoiding large expanses of paved areas, large featureless buildings, and monotonous or franchise-style architecture. (See Figure 1234.10.) 
 
      4.   All sides of a building open to view by the public shall display a similar level of architectural quality, and shall be subdivided and proportioned using features such as windows, entrances, arcades, awnings, or other such features.
      5.   Wherever feasible, buildings shall be designed to provide massing configurations with a variety of different wall planes. Plain, monolithic structures with long monotonous walls and roof plane surfaces are prohibited.
      6.   Each building facade shall incorporate design elements for each 20 horizontal feet, such as changes in color or texture; projections, recesses, and reveals; arcades or pergolas providing pedestrian interest; or equivalent elements that subdivides the wall into human scale proportions.
      7.   First floor facades facing streets or pedestrian ways should incorporate large amounts (at least 60% of the facade) of clear windows that permit views into the interior of the building and/or product display areas. 
      8.   Building facades shall have highly visible customer service entrances that feature canopies, overhangs, arcades, distinctive roof forms, arches, display windows, or landscaped features. Primary entrances should face, and be visible from the street on which they are located and shall be directly accessible and visible from the sidewalk.
      9.   Buildings shall have well defined rooflines with attention to architectural detail. Consideration should be given to the prevailing pattern of roofs in the area surrounding and within the district.
      10.   Sloping roofs, where used, shall have one or more of the following architectural features: gables, hips, horizontal or vertical breaks, or other similar techniques that are integrated into the building architecture.
      11.   Buildings shall be designed and arranged to define the public and private space with open views and surveillance for public areas and privacy for private areas.
   C.   Building Materials.
      1.   Building materials shall be limited to brick, masonry, stucco, wood, fiber cement siding, wood shingle, wood siding, cultured stone, or other similar materials.
      2.   Prohibited materials include vinyl siding, dryvit-type products on the lowest 8 feet of any structure, split faced block, aluminum or vinyl siding, and other similar materials.
   D.   Vehicular Circulation and Access.
      1.   Circulation systems shall be designed to efficiently facilitate traffic flow, yet designed to discourage speeds and volumes that impede pedestrian activity and safety.
      2.   Street designs are encouraged to incorporate traffic calming devices and techniques.
      3.   Common or shared access points are encouraged.
      4.   To the maximum extent feasible, common or shared service and delivery access shall be provided between adjacent parcels or buildings, and provided to the rear of buildings.
      5.   Safe and adequate sight distance shall be provided at all intersections, as provided in Section 1260.05.
      6.   Transit stops should be incorporated into site plans, where
         feasible.
      7.   Traffic impact studies, when required by the Zoning Administrator, shall be provided as part of the site plan review process.
   E.   Pedestrian Access and Circulation.
      1.   A coordinated pedestrian system shall be provided throughout the development, including connections between uses on the site, and between the site and adjacent properties and rights-of-way. Pedestrian connections shall be provided to properties across streets wherever feasible.
      2.   The site shall be connected to adjacent properties and pedestrian facilities to the maximum extent feasible.
      3.   Continuous sidewalks or other pedestrian facilities shall be provided between the primary entrances to buildings, all parking areas that serve the buildings, pedestrian facilities on adjacent properties that extend to the boundaries shared with the development, any public sidewalk along perimeter streets, or other community amenities or gathering spaces.
      4.   Pedestrian-scale lighting fixtures shall be provided along all sidewalks and walkways to provide ample lighting during nighttime hours.
      5.   Decorative sidewalk materials, such as brick pavers, shall be provided at key intersections or streets.
      6.   Street furniture or other amenities are encouraged, such as plazas, benches, and decorative pedestrian light fixtures.
      7.   Open and public space should be provided as a mixture of green space landscaping and hardscape pedestrian areas:
         a.   Development proposals that involve a minimum of 1.5 acres or 60,000 square feet of floor area, whichever is less, should provide a minimum of 5% of the project site as public open space.
         b.   Residential buildings should provide 10% of the site area as open space.
   F.   Parking Lot Design and Layout.
      1.   The visual impact of off-street parking lots shall be minimized through the use of interior landscaped islands, and through dividing parking spaces into groupings.
      2.   The edges of parking lots shall be screened through landscaping or other methods such as decorative fences in accordance with Section 1253.08.
      3.   Semi-pervious paving materials, such as permeable pavers, porous asphalt or porous concrete, are encouraged so as to permit natural percolation of water.  Such materials shall be installed and maintained in accordance with industry and manufacturer standards and the following:
         a.   The manufacturer's specifications are applicable to the subject property's particular soil type and slope (gradient) so that vehicles are supported without rutting and water percolation is achieved.
         b.   Semi-pervious parking areas must allow storm water to percolate into the ground at a rate sufficient to accommodate the five-year, 24-hour storm event.
         c.   For non-residential uses, if only a portion of the parking area is designated for semi-pervious materials, the area designated for semipervious parking shall be located at the perimeter of the parking lot, and if possible, remote or furthest removed from the principal building.
      4.   Parking structures shall be designed to be compatible with the adjacent buildings and district architecture and shall provide clearly marked pedestrian connections to the sidewalk.
   G.   Landscaping and Screening.
