The purpose of the Mixed Use Development Zone is to provide a variety of uses (limited commercial, office and residential) as an appropriate transition between high-traffic arterial streets and nearby residential uses. This district is intended to ensure compatibility of new development and residential conversions with existing and future residential development. It is also intended to ensure as well as encourage assemblage of properties in a unified plan with a coordinated and harmonious development which will promote outstanding design without unsightly and unsafe strip commercial development. Specific measures to mitigate negative impacts of mixed use developments include standards for perimeter walls, vehicular access, lighting, signage, and mitigations of other reasonably anticipated detrimental effects will be required at the time of design and site plan approval. Landscaping shall be installed as set forth in MKZ 18.64, Landscape Standards.

The Mixed Use Development Zone (MD-3) is a legacy zoning district and shall only be applied to existing parcels, lots, and areas already included in the Mixed Use Development Zone (MD-3). No additional parcels, lots, or land may be added the MD-3 zoning district. Development in the Mixed Development (MD-3) Zone may be subject to the requirements set forth in MKZ 18.61, Sensitive Lands.

Uses in the Mixed Use Development Zone (MD-3) are as determined by the Table 18.42-1 Permitted and Conditional Uses in the Mixed Use Development Zone (MD-3). If a use is not explicitly designated in the table, then the use is prohibited. An applicant seeking a Millcreek Business License may submit a Classification Request by following the procedure as set forth in MKZ 18.15.030 (J), to determine whether a proposed land use aligns with an existing land use listed in Table 18-42.1.

Commercial uses shall not be open for business before six a.m. or after eleven p.m.

The uses specified in this chapter for the MD-3 zone shall be permitted only under the following conditions:

1. No manufacturing is allowed;
2. No outside storage of any stock, motor vehicles or other property is allowed except for two delivery vehicles three-quarter ton or smaller.

The minimum setbacks, maximum height and lot size requirements are as set forth in Table 18.42-2 Spatial Requirements for the Mixed Use Development Zone.

Design and site plan approval including, but not limited to, architecture, building materials, lighting, signage, vehicular access and noise for all development in the MD-3 zone is required by the Planning Commission as a conditional use pursuant to the requirements of MKZ 18.15.030 (A).

1. All mixed use developments shall have a decorative tinted concrete or masonry wall on all rear and side yards fronting a public street that. The perimeter wall shall comply with the standards set forth in MKZ 18.66, Fences and Retaining Walls.
2. All perimeter walls shall be a minimum of six feet high unless the Planning Commission requires a higher wall as part of the conditional use approval.

Landscaping shall be as specified in MKZ 18.64, Landscape Standards, including the buffering requirements set forth in MKZ 18.64.050.

Lighting shall be as specified in MKZ 18.68, Outdoor Lighting.

The noise level emanating from any use or operation shall not exceed the limits established by the Salt Lake County Health Department, or its successor, regarding noise control. The noise level shall not in any case exceed five decibels above the ambient level of the area measured at the property line. For the purposes of compliance with health regulation number twenty-one all properties located within a mixed development zone shall be considered residential.

The number of access points along public streets shall be minimized by sharing and linking parking areas with adjacent properties. Reciprocal ingress and egress, circulation and parking agreements shall be required to facilitate the ease of vehicular movement between abutting properties. On corner sites access points shall be located as far from the corner as reasonably possible and in no case less than forty feet from the point of intersection of the property lines Vehicular circulation shall be designed to limit the intrusion of traffic into residential areas and minimize access on streets used by schoolchildren.

No use shall be permitted which creates odor in such quantity as to be readily detectable beyond the boundaries of the site.

In order to meet the purposes of this chapter the Planning Commission shall consider the following prior to approval of any plan:

1. Lots or parcels should be accumulated to provide the minimum lot area. Individual lots or parcels with an area smaller than the minimum lot area are not suitable for a mixed development.
2. The development shall provide on-site amenities and appropriate buffering to abutting properties and uses.
3. The scale of the development shall be in character with the surrounding land uses.
4. Safe access shall be provided within the site and to public streets.
5. The development shall have a residential character if adjacent to residential areas.
