A. Landscape Options

Development in Site Design Category 3 must provide landscaping along sidewalks where building façades are not located within the minimum frontage area to enhance community image and support pedestrian activity, using one (1) of the following methods:

1. Planted Buffer with No Fence or Wall

A landscaped area at the sidewalk edge that is at least twenty (20) feet deep with a minimum of seventy (70) percent porous/permeable surfaces and fifty (50) percent planted material.

2. Planted Buffer with a Fence or Wall

A landscaped area at the sidewalk edge that is at least ten (10) feet deep with a minimum of seventy (70) percent porous/permeable surfaces and fifty (50) percent planted material. A fence or wall must be located within the landscape area and include posts, columns, and/or pedestrian gateways a minimum of every one hundred (100) feet (⇔ See Section 18.50.050 for fence height and design).

3. Plaza or Courtyard

An area that is paved but also includes amenities; these may include plant materials, sculptural or water features, public art or outdoor seating.

B. Outdoor Amenity Space Options

Development in Site Design Category 3 that is greater than four (4) acres in size or includes more than sixty-five (65) percent open space (low coverage of buildings) must include outdoor amenity space to enhance the public realm and promote pedestrian activity. Select one (1) or more of the following methods to cover at least ten (10) percent of the site area:

1. Plaza or Courtyard

A common use area directly accessible from adjoining buildings that includes decorative paving, street furniture, planters and/or pergolas or other shade structures.

2. Common Area

A common green space shared by users of the development that may include a lawn, a stand of trees, or shrubs.

3. Water Feature

A fountain or decorative pool shared by users of the development (note that properly designed artificial drainage areas may also be used to meet common open space standards).

4. Natural Feature

Stands of mature trees or natural drainage areas retained as an amenity for users of the development.

C. Street Frontage Area

Street frontage area for commercial and mixed-use buildings in Site Design Category 3 must be a maximum of fifteen (15) feet as measured from the property line.

D. Façade Width in Frontage Area

The façade width within the frontage area of a site must be a minimum of thirty (30) percent of the lot width for commercial and mixed-use buildings as illustrated in Figure 1 of this section. The Planning Official may reduce the required façade width in the setback area to support preservation of significant trees or tree clusters.

E. Parking Pod Size

The maximum number of parking stalls allowed in one (1) parking pod, as illustrated in Figure 1 of this section, is forty (40).

F. Street Connectivity

Development in Site Design Category 3 must provide an internal public or private street system with a connectivity ratio of at least 1.7 (See Section 18.30.220).

G. Pedestrian Connectivity

2. Additional Pedestrian Connection Options

Development in Site Design Category 3 must provide enhanced pedestrian connections to encourage pedestrian use, integrate with surrounding land uses or connect to regional paths and trails. Select at least two (2) of the following methods:

a. Pedestrian Gateway

Provide at least one (1) defined pedestrian gateway into the site using landscape and hardscape materials.

b. Cross Property Connection

Provide at least one (1) dedicated pedestrian connection across the development defined with wide sidewalks, special paving material or landscaping.

c. Pedestrian Connection to Adjacent Development

Provide at least one (1) dedicated off-street pedestrian and bicycle connection to an adjacent residential, commercial or mixed-use development, or to an adjacent transit stop.

d. Pedestrian Connection to Regional Trail

Provide at least one (1) dedicated pedestrian and bicycle connection to an adjacent pedestrian or multi-use trail.

H. Connectivity to Adjacent Driveways

Development in Site Design Category 3 requires connections to driveways on adjacent properties where possible.

I. Drainage Features

Open drainage and detention areas visible to the public must be incorporated into the design of the site as an attractive amenity or focal point, using at least one (1) of the following methods:

1. Pond or Fountain

A wet-bottom basin in a prominent location that is enhanced with decorative features such as fountains, waterfalls, and/or extensive landscaping.

2. Landscaped Basin or Channel

A dry-bottom basin or channel that is maintained as extensively landscaped open space or yard area, designed with shallow slopes and a curvilinear, nongeometric shape to avoid an artificial appearance.

3. Natural Drainage Feature

Preservation of natural drainage areas including existing trees and vegetation. If existing trees and vegetation are missing or removed, new trees, shrubs, and plants should be added to restore the appearance of natural landscaping.

4. Geometric Basin

Artificial geometrically shaped basins should generally be avoided, but may be used in areas that are not visible to the public or from adjacent property.
