Site development standards shall be in accordance with Table 15.4.1 ¹⁹⁹

Single-family residential and attached-unit building shall be limited to 2 1/2 stories (35 feet).

1. Each attached-unit building shall include variation in color or shade of color and incorporate front facade articulation through the differentiation of individual units with placement of dormers, window variations, and entry features. Additional articulation shall be achieved by:
   1. Variations in the setback of the facade of the building by at least two feet between adjoining units; or
   2. Horizontal or vertical shift in roofline of at least two feet at intervals not greater than two attached units with variations in roof pitch, overhangs, and projections.
2. Buildings with attached units that back or front along the perimeter of the development visible to an outside street or trail shall avoid the appearance of a flat wall through two-foot shifts in wall of alternating units and minimum four-inch stucco or cement board wrap of all rear wall corners.
3. Buildings with four or more attached units shall provide:
   1. A mixture of four, five, or six-unit buildings that alternate in color or shade of color; or
   2. Include articulation in roofline
4. Buildings with five or six units may be used back-to-back in the interior of the development.

Only detached single-family homes may be built next to off-site, existing dwellings in the R-1-8, R-1-9, R-1-10, and R-1-15 zones, where there is no significant existing geographical or infrastructural buffer (e.g. highway, canal, waterway). Fencing alone does not apply as a buffer. In such cases, the following shall apply:

1. Single-family lots must comprise 50% of the R-M development area.
2. The first layer of lots immediately abutting the existing R-1 zone must be sized at no less than 50% the minimum average square footage required by the R-1 zone.
3. Developer may use open space to replace the fist layer, if the open space depth is at least one-half the minimum required lot depth of the adjacent R-1 zone.
