This chapter applies to single-family residential structures in new residential development projects in the following Suburban Residential Districts: SR-12000, SR-9000, NR, RMU, CMU, EMU and HMU-S. (Ord. 603, 11-1-2018)

Houses should be designed and sited to conform to the natural terrain as much as possible and to take advantage of views. In tracts, houses should be located on their lots so as to create interest and varying vistas as a person moves along the street. In order to prevent a tract from exhibiting a row-house effect, no more than two (2) adjacent residences should have the same setback; and the minimum setback variation should be three feet (3'). Care should be exercised that no house is located in such a manner to create an objectionable overview which invades the privacy of an adjoining unit. (Ord. 603, 11-1-2018)

The County encourages variations of architectural theme. However, it shall be the responsibility of the designer to coordinate the design with adjacent developments so that the design does not conflict with the character of the neighborhood as a whole. Within a tract, architectural styles should remain uniform.

Material changes within a building shall be offset in plane or an entirely different design element. Detailing of construction elements is another important consideration. For example, exterior metal portions of the structure (i.e., vent pipes and flashings) should be painted to blend with the adjacent roof or wall material. In addition, the vent pipes should be consolidated where possible by design. Also, thought should be given to locating mechanical units in some area other than the roof. Where units are located on the roof, then the units shall be screened in manner that is architecturally integrated with the design of the house. (Ord. 603, 11-1-2018)

Houses should vary in color and character within the development. However, no one structure should be at such variance with its neighbors that it detracts from the character of the street as a whole. (Ord. 603, 11-1-2018)

   A.   In new subdivisions or developments and infill developments a solid block wall or wooden fence a minimum of six feet (6') in height shall be provided along side and rear lot lines of parcels twelve thousand (12,000) square feet or less to provide privacy and screening.

   B.   When there is an existing well-maintained fence, new fencing requirements may be waived.

   C.   Adjacent to a collector and arterial streets rights-of-way required fences shall be constructed of decorative block, brick, or stucco, or similar decorative masonry material.

   D.   Wrought iron fencing or combination block and wrought iron fencing may be utilized in place of the fences required above to preserve views or provide greater openness.

   E.   The Planning Commission may waive fencing requirements in hillside areas where side and/or rear lot line slope is extremely severe and it can be shown that fencing will serve no purpose. (Ord. 603, 11-1-2018)

All new dwelling units shall utilize non-combustible roofing materials. (Ord. 603, 11-1-2018)

The following special requirements and performance standards shall apply to properties located in Residential Zoning Districts, except as otherwise authorized through approval of a planned development:

   A.   Required Landscaping: Required front and street side yards shall be landscaped in conformance with chapter 402 of this title.

   B.   Building Height Exceptions: Chimneys, vents and church steeples may exceed the maximum height requirement of the zoning district.

   C.   Sight Distance Requirements: At all street, alley and driveway intersections there shall be triangular yard area within which no tree, sight-obscuring fence, shrub, wall or other visual obstruction shall be permitted higher than thirty inches (30") above the adjacent street, alley or driveway grade. This triangular area shall measure as follows:

      1.   At any intersection of two (2) street rights-of-way, two (2) sides of the triangular area shall extend twenty feet (20') along both right-of-way lines, measured from their point of intersection. For the purpose of this subsection, an alley shall be considered as a street.

      2.   At any intersection of a driveway with a street or alley, the sides of the triangle shall extend ten feet (10') along the street or alley right-of-way and fifteen feet (15') along the edge of the driveway, measured from their point of intersection.

      3.   The provisions of this subsection shall be in addition to any other site distance protection requirements of the County, and in the event of conflict between requirements, the more restrictive shall apply.

   D.   Mechanical Equipment: Air conditioners, heating, cooling, ventilating equipment, swimming pool pumps and heaters, and other similar mechanical equipment shall be screened from surrounding properties and streets.

   E.   Driveway Setback: A driveway located in front of a garage accessed through the front yard shall not be less than twenty feet (20') in length as measured from the garage to the right-of- way line.

   F.   Wireless Communication Facilities: Wireless communication facilities located in the Residential Zones when allowed by this chapter shall be subject to the provisions of chapter 236 of this title and all other applicable requirements.

   G.   Shipping Containers: No shipping container may be placed on any Residentially zoned property in a suburban character area. (Ord. 603, 11-1-2018)
