Site Plan & Design Elements 38.520.030 -Relationship to adjacent properties Balconies –rear & side yards adjacent to residential zones Site Plan & Design Elements 38.520.040 -Non-motorized circulation & design 1.Access to sidewalk 2.Internal circulation 3.Pathway design 4.Bicycle facilities 38.520.050 -Vehicular circulation & parking 1.Driveways 2.Inter-site connectivity 3.Internal roadway design (including drive-through facilities Site Plan & Design Elements The examples above include angled parking and planter strips with street trees. Pedestrian-scaled lighting also contributes to the character in the upper right image. The above left image illustrates a thoroughfare lane with a row of street trees. A sidewalk is included on one side of the street to provide a strategic connection between businesses. The right image illustrates the curbless “woonerf” design where travel speeds are low and lanes are shared between pedestrians and vehicles. Figure 38.520.050.D Good internal roadway examples. 38.520.060 -Internal open space 1.Usable residential open space Common open space Ground floor private yards Balconies Common indoor recreation areas Shared roof decks 2.38.520.070 -Service support considerations Site Plan & Design Elements The upper examples include a combination of open lawn area for informal recreation plus walkways and decorative landscape areas to enhance the setting for residents. The left image above includes a covered gathering space with outdoor grills adjacent to a landscaped commons with a central pathway.The right image includes a pond/wetland type area with boardwalk and seating areas. Figure 38.520.060.B.2 Common open space examples. 1.Usable residential open space 38.520.060 -Internal open space 1.Usable commercial open space –developments larger than one (1) acre; 2%. See figure 38.520.060.D.2. Does not include M-1 and M-2. The “development envelope” on both sites is 102,400sf(2.35 acres). The minimum amount of usable commercial open space (2% of development envelope) is 2,048sf. The left example consolidates the open space into one plaza near the major building entry. The right example includes three separate open spaces at strategic, visible locations. Figure 38.520.060.C Example site development integrating usable commercial open space. Site Plan & Design Elements 38.520.060 -Internal open space Site Plan & Design Elements Figure 38.520.060.D.1 Example of a small pedestrian-oriented open space 38.520.070 -Service support considerations 1.Location of ground related service areas & mechanical equipment. 2.Screening of ground related service areas & requirement 3.Utility meters, electrical conduit & other apparatus 4.Roof mounted mechanical equipment Site Plan & Design Elements Place utility meters in less visible locations. The upper and lower left examples are successfully tucked away in a less visible location and/or screened by vegetation. The right images are poorly executed and would not be permitted in such visible locations. Such meters must be coordinated and better integrated with the architecture of the building. Figure 38.520.070.D Utility meter location and screening –good and bad examples Site Plan & Design Elements All three examples use durable and attractive enclosures with trees and shrubs to soften views of the enclosures from the side. The lower left example uses a trellis structure on top –a desirable example particularly where the top of the enclosures are visible from surrounding buildings, streets, and walkways (due to topography or building heights). Figure 38.520.070.C Acceptable screening enclosures Site Plan & Design Elements Departures to the provisions of subsections C.1 and 2 above will be considered provided the enclosure and landscaping treatment meet the intent of the standards and add visual interest to site users. All three examples use durable and attractive enclosures with trees and shrubs to soften views of the enclosures from the side. The lower left example uses a trellis structure on top –a desirable example particularly where the top of the enclosures are visible from surrounding buildings, streets, and walkways (due to topography or building heights).

Industrial zones may employ different provisions. NCOD applicability Building Design 38.530.030 –Character NCOD conformance Architecture that is defined predominately by corporate identity features, aka, franchise architecture. Additional guidance being developed o Definition -a type of retail sales activity or retail sales establishment that has eleven or more other retail sales establishments in operation, or with local land use or permit entitlements already approved, located anywhere in the world. In addition to the eleven or more other retail sales establishments located in the World, maintains two or more of the following features: a standardized array of merchandise, a standardized facade, a standardized decor and color scheme, a uniform apparel, standardized signage, a trademark or a servicemark.”In other words, retail stores with multiple locations and a recognizable "look" or appearance.

The left portion of Building 1 uses a very simple cornice line –to go with the upper level setback. Building 2 uses a traditional cornice line. Figure 38.530.050.E Examples of buildings employing confident and distinctive rooflines. Building 3 uses capped projecting columns along with an understated cornice line. Building 4 uses a very simple roofline –which is acceptable in this case due to the prominence of the wooden canopy.
