§ A18-6 SPECIAL PERFORMANCE STANDARDS.
   (A)   In order to ensure quality building and site design within this mixed use planned development, special standards are necessary. These include regulations governing landscaping, building materials, signage, lighting, noise, storage, ratios of impervious materials coverage, and access point for pedestrians and vehicles.
   (B)   Site design. The following design elements shall be incorporated into all site plans for commercial buildings in any subzone. The goal of these regulations is to assure that commercial uses are laid out in a manner which makes them compatible with adjacent residential areas and complementary to the image of the community as a whole.
      (1)   Traffic circulation patterns and ingress and egress to the site shall be designed so as to minimize the impact on adjacent residential uses.
      (2)   The site shall be organized so that there can be a smooth flow of vehicles in and out of the site as well as easy access to the various activity areas.
      (3)   Entrances and exits shall be placed in accordance with city requirements so as to minimize interference with off-site circulation patterns.
      (4)   Circulation at gas pumps shall not conflict with access to parking, interior vehicular circulation or access to and from public streets.
      (5)   Provision shall be made for emergency vehicle access and fire lanes adjacent to the building.
      (6)   Parking shall be provided in the quantities recommended by the city parking guidelines. Parking for convenience shopping centers shall be provided at a minimum of one space per 200 square feet of gross floor area. All parking areas and stalls shall be designed to city standards.

      (11)   Service and loading to the fronts of buildings may be permitted, provided the rear of the building abuts a residential zoning district.
      (12)   Loading/service areas, refuse containers and storage containers, located on the side or rear of buildings, shall be screened from view from adjacent streets and residential areas through the use of extensive six-foot high planting and/or opaque masonry screening walls. Masonry shall be the same material used on the exterior of the main structure.
      (13)   Outdoor storage and display shall be prohibited. All utility meters and services to the building shall be screened from view or contained within the building.
      (14)   Screening walls or fences shall be at least six feet in height, but not more than eight feet in height. Lower walls may be used to help screen parking and circulation areas.
      (15)   Fences or walls shall be constructed of a masonry material similar to and complimentary to the primary building material and architecture. (Chain link type fence with or without wood slats or other inserts shall not be an acceptable screening device.) Fencing shall not impair traffic safety by obscuring views of entering or exiting motorists.
      (16)   Decorative or protective wrought iron type fences may be allowed when incorporated properly within a site plan.
   (C)   Landscaping. The following design standards shall be incorporated into all sites plans for commercial building in any subzone.

      (1)   Plant materials, fences and walls shall be utilized to:
         (a)   Provide screening of undesirable views;
         (b)   Compliment the architectural form of the building;
         (c)   Define walkways, traffic circulation, special use areas and building entries;
         (d)   Provide a pleasant street appearance;
         (e)   Soften the visual impact of large paved areas;
         (f)   Soften the edge between a parking lot or street and the building; and

      (3)   The landscape treatment of the space abutting the public right-of-way shall include deciduous canopy trees in concert with berming or other screening devices to conceal parking and circulation areas.
      (4)   Planting beds, conifers and ornamental trees shall be used to accent entries and freestanding signage.
      (5)   Signage and identity structures shall be incorporated into the landscape design and shown on landscape or site plans.
      (6)   At least 75% of the “landscape area” shall be live plant material as opposed to walks, patios, and the like. Plant materials used in planting beds shall be sized to achieve a minimum of 50% bed coverage within two years of installation.
      (7)   Installation of trees and evergreens at larger than minimum city standards may be required by the city to achieve buffering or streetscape effect in some circumstances.
      (8)   The architectural design shall include plaza, patios and outdoor seating adjacent to building entries.
      (9)   Special paving materials (brick pavers, stamped concrete, paving stones, and the like) may be used to define pedestrian circulation through parking and vehicular circulation areas.
      (10)   Paths and sidewalks (a minimum five feet in width) shall be provided to assure that pedestrians can move safely and conveniently on the site and between the site and the neighborhood.
      (11)   In all turf and landscape areas, an in- ground landscape irrigation system shall be installed. The systems shall be considered a portion of the cost of the building (not the landscaping) and shall be inspected as part of the building construction.
   (D)   Outdoor lighting. The following lighting standards elements shall be incorporated into all site plans for commercial buildings in any subzone.
