      1. All street-facing facades must have landscaping along the foundation. There must be at least one three-gallon shrub for every three lineal feet of foundation. (R)

      2. Sixty percent of the area between the front lot line and the front building line must be landscaped. At a minimum, the required landscaped area must be planted with living ground cover. Up to one-third of the required landscaped area may be for recreational use, or for use by pedestrians. Examples include walkways, play areas, or patios. (R)

      3. Use of planting materials and landscape structures such as trellises, raised beds and fencing to unify the overall site design is encouraged, with plantings consistent with L3 open area landscaping standard of SMC 17C.200.030.(P)

      5. Duplexes and attached houses on corner lots shall be designed so each unit is oriented towards a different street. This gives the structure the overall appearance of a house when viewed from either street. (R)

      6. All units must meet the following standards. Adjustments to this paragraph are prohibited, but modifications may be requested through a design departure. The standards are:

        1. Entrances. Each of the units fronting on the street must have its address, windows, and main entrance oriented toward a street frontage.  Units that are on the interior of a parent site may be oriented toward a private access or shared open space. Where an existing house is being converted to two units, one main entrance with internal access to both units is allowed. (R)

        2. Each unit must have a covered, main entry-related porch or stoop area of at least fifty square feet with no dimension less than five feet. (R)

        3. Attached units must be modulated along the public street at least every thirty feet. Building modulations must step the building wall back or forward at least four feet. (R)

        4. Reduce the potential impact of new Pocket Residential Development on established and historic neighborhoods by incorporating elements and forms from nearby buildings. This may include reference to architectural details, building massing, proportionality, and use of high-quality materials such as wood, brick, and stone. (P)  

        5. Create a human scale streetscape by including vertical and horizontal patterns as expressed by bays, belt lines, doors and windows. (P)
