(1) Single and multiple family residential developments containing any type or mixture of housing units are permitted, including, but not limited to clustered development, townhouses, condominiums, atrium or patio houses, detached houses, duplexes, garden apartments, and high-rise apartments. In single and two-family zoning districts, dwelling units may be clustered in common-wall construction with a maximum of six (6) consecutively attached units. Such units may have no more than two (2) walls in common, with no units above other units. Mobile homes, hotels, motels, boarding houses, or other similar transient residential facilities are not permitted.
(2) Permitted uses in a PRUD shall also include private recreational facilities for the exclusive use of the occupants of the PRUD and their guests, when approved as part of the final PRUD plan.
(3) In addition to permitted residential and recreational uses, a PRUD may provide offices and professional service uses in a planned environment. Where a PRUD proposes a mix of residential and office uses, the Planning Commission and City Council should make the following findings as part of the approved preliminary and final PRUD plan:
(a) The proposed PRUD will provide a pleasant and attractive environment in which the relationship of land uses is properly planned to assure a harmonious development;
(b) The proposed PRUD will create no detriment to adjacent properties or to the general area in which it is located; and that it will be in harmony with the characteristics of the community and the existing development in the area; and
(c) That the proposed PRUD will provide for the efficient utilization of land and the open space is in reasonable proportion to residential densities and the intensity of office and professional service uses.
(4) In considering non-residential land uses as part of a PRUD plan, the Planning Commission and City Council shall address the following:
(a) Size of project. The proposed PRUD must propose a minimum of fifty (50) units and be at least forty (40) acres in order for the Planning Commission and City Council to consider office and professional service uses as part of the PRUD plan. Office and professional service uses shall not occupy more than ten percent (10%) of the PRUD project site.
(b) Architecture. The proposed non-residential structures should be complementary to the surrounding and historic architecture in terms of scale, massing, roof shape, exterior materials, etc. New buildings should not create large bulky masses, but should be scaled down into groupings of smaller attached structures.
(c) Building Height. Buildings should be limited to two (2) stories or thirty-five feet (35').
(d) Parking. Large expanses of asphalt should be reduced and broken into smaller parking lots. Parking lots should include ample landscaping to buffer cars from neighboring properties.
(e) Access. Adequate vehicular and pedestrian access must be provided. Access from an arterial or collector street to the office and professional service uses must be provided. A traffic impact study shall be required, as part of the preliminary PRUD plan, to project auto and truck traffic generated by the uses proposed. The traffic impact study must be prepared by a registered traffic engineer. The traffic study shall include an analysis of on-site circulation, capacities of existing streets, number of additional trips which will be generated, origin/destination studies and peak traffic generation movements.
(f) Rooflines. Flat or low-pitched roofs should be avoided and rooflines should blend in with surrounding and historic buildings.
(g) Materials. New buildings should blend with the materials of surrounding and historic buildings.
(h) Signage. Signage for the non-residential buildings should be part of a coordinated signage system for the entire PRUD project. Signage should help unify the project and provide a positive image. Natural materials such as wood, stone, rock, and metal with external illumination are encouraged. The size and location of signage shall conform to the requirements and guidelines for monument signage from Sections 20.04.100 and 20.04.110 of the Layton Municipal Code.
(i) Lighting. Outdoor lighting should be screened by shields or hoods to prevent glare onto adjacent properties. The intensity of larger fixtures should be reduced by utilizing a larger number of smaller light poles of twelve to eighteen feet (12' - 18'). Incandescent lights should be used in smaller pedestrian spaces where quality light is especially important. In addition to these guidelines, plan and specifications for all exterior lighting installed adjacent to residential areas shall be submitted for approval as outlined in Section 19.06.010 of the Layton Municipal Code.
(j) Buffers. A buffer between residential and non-residential uses within and adjacent to the PRUD shall be a minimum of at least sixty feet (60'). Said buffer may include open space areas, pedestrian trails and landscaped areas and may be counted toward the base open space requirement for the PRUD project.
