   A.   Purpose: This zone is intended for the development of higher- density residential areas with a variety of housing options, including small lot subdivisions when part of a planned development or attached or detached multi-family units, condominiums, townhouses, apartments, or live-work units in a traditional town or suburban setting located near major transportation facilities, supporting commercial and commercial mixed-uses, civic uses, and parks. This district has a minimum net parcel size of four thousand five hundred (4,500) square feet with six thousand (6,000) square foot minimum average, and a maximum density of eighteen (18) units per acre. Secondary uses within this zone are open space, parks, pathways, schools, and other public uses. The RMU Zone implements the suburban residential land use designation of the Master Plan in Suburban Character Districts.

RMU development provides a mix of complementary designed and located residential uses, including single-family and multifamily uses, attached and detached, condominiums and special living facilities, with the opportunity for retail and services as subservient uses on a project and district level (less than 20 percent of total development). The RMU development should strive to achieve project sites designed for pedestrian, bicycle and vehicle access and circulation and connections to the adjacent land uses. It should also create public focal points and activity centers and provide a sense of community for the occupants and the neighborhood.

   F.   Miscellaneous Requirements:

      1.   The intent of the Mixed Use Residential District is to provide a mix of residential and commercial uses within one project and throughout the district. To accomplish this while providing flexibility of design, two (2) development options are offered:

         a.   Residential development (100 percent) - commercial provision. The proposed development shall provide for both residential uses and commercial use(s). The commercial portion of the development may occupy up to a maximum of twenty percent (20%) of the project site or floor area. When twenty percent (20%) of the site is dedicated for commercial use, the residential component of the project is allowed to be built out at a density equivalent to one hundred percent (100%) of the gross site.

         b.   Mix and location of uses.

            (1)   All RMU development, except those meeting the criteria below for infill development, shall provide a mix of residential unit types. A maximum of thirty percent (30%) of any one type of residential units is allowed. Residential units incorporating home occupations shall not count as a separate unit type.

            (2)   Up to twenty percent (20%) of the acreage of the RMU development may be devoted to commercial uses (not including home occupations).

            (3)   Except for home occupations, commercial uses that are included shall be located along collectors, at corners, or adjacent/across from common open spaces.

            (4)   Infill development within the RMU District. Where an existing parcel within the RMU District is one acre or less, development projects may consist of a single residential unit type or a combination residential and commercial mix consistent with the development standards contained in this title.

         c.   Pedestrian connections shall be made from residential uses along all major streets and from homes to all common open spaces and to all civic and public uses and landmarks. Pedestrian connections that cannot be made as sidewalks along vehicle lanes shall be made as alternative access easements such as trails.

         d.   A hierarchy of interconnected streets that form a grid pattern shall be provided in any RMU development, including major collectors (boulevards), local streets, and alleys. In local street patterns, walkable blocks of five hundred (500) linear feet or less are required.

         e.   New RMU developments must connect to existing neighboring developments where connections are provided and must provide new connections to future neighboring developments.

         f.   Street standards shall be consistent with Lyon County Development Standards.

         g.   The Public Works Director may allow for a reduction of local street width to forty one feet (41'), based on a cross-section of two (2) 10-foot vehicle lanes, two (2) 6-inch curbs, two (2) 5- foot planting/utility strips, and two (2) 5-foot sidewalks.

         h.   Parallel parking may be provided on one or both sides of local and major streets.

         i.   All RMU developments shall meet parking standards of chapter 401 of this title. Shared parking is encouraged where participating users have differing peak parking hours. The Director may reduce parking requirements, when a parking study prepared by a professional transportation engineer indicates that a reduction in parking will cause no negative impacts to streets or neighbors.

         j.   All parking, including parking lots, improved or unimproved parking stalls/spaces, and/or parking garages/structures shall occur in the rear or side of the lot and shall be located a minimum of ten feet (10') behind the front building wall of the primary structure, except for parking located within a mixed use building.

         a.   The design standards of chapters 340, 342, 343, 344, 345, 346, 347, and 348 of this title, residential standards, shall apply to all proposed residential development within RMU Districts, unless otherwise specified by this chapter.

         b.   The design standards of the Commercial Zoning District, chapter 360 of this title, design standards, shall apply to all proposed commercial development within the Mixed Use Zoning Districts, unless otherwise specified by this chapter.

         c.   The following design standards supplement those found in subsections F2a and F2b of this section, and shall apply to all development proposed within the RMU District.

            (1)   Commercial areas should be placed within walking distance (1/4 mile) of residences;

            (2)   Commercial buildings and uses should be located at the corner of the intersection of two (2) public streets;

            (4)   All primary building pedestrian entrances and storefront windows shall face onto the primary street serving the site. If the site has multiple street frontages, the more pedestrian- oriented street shall take precedence;

            (5)   The design character of an individual building should be compatible (share similar features such as color, scale, massing and height) with its neighbors but may also include other features or characteristics that are different;

            (6)   The requirements of chapter 402, "Landscape Standards", of this title, shall apply to all proposed development within the Mixed Use Districts;

            (7)   Drive-through facilities are not permitted.
