It is the primary purpose of this S-3 Mixed Use Development (MXD) District to provide large scale areas in the City within which commercial, light industrial, and residential uses can locate with the assurance of a high permanent level of design quality, extensive site amenity, open space and compatibility with existing land uses. Stringent site planning, aesthetically desirable design, screening standards, buffer strips, sign requirements and other appropriate procedures will be used to achieve the desired results of compatibility with existing uses and protection between future residential and nonresidential land uses.

As this S-3 MXD District will be a unique setting with a wide array of land uses, it requires a site with a minimum size of 80 acres for said designation.

1. Any uses permitted in the Residential Zoning Districts. Residential development shall occur on tracts of a minimum size of five acres and an open space buffer 50 feet wide, within which no structure is permitted, is required to separate all non-residential uses from residential uses.
2. Any uses permitted in the M-1 Light Industrial Zoning District, further including such uses as research and development facilities, industrial parks, and office parks shall occur on tracts of a minimum size of five acres. In the case of minor residential streets, the minimum right-of-way may be 50 feet.

1. Those uses listed as Conditional Uses in the Residential Zoning District.
2. Those uses listed as Conditional Uses in the M-1 Light Industrial Zoning District.

The subdivision of any real estate within the S-3 MXD District shall be in accordance with Title 11, Subdivision Regulations, of the City Code. To facilitate the development approval process a preliminary site plan may be submitted to the Planning and Zoning Commission. If Commission approval is granted on the preliminary site plan, the developer then has the assurance that the proposal is consistent with the intent of the S-3 MXD District. The following preliminary site plan information shall be required, but not limited to, such criteria as:

1. Proposed facility description, including type of use, process, or service, approximate number of employees on initial start and within five years.
2. Information on traffic generation, deliveries, employee parking, and public access to the facility.
3. Information on required utilities, utility extensions if required, and any unique requirements for material disposal or pre-treatment of sanitary sewage.
4. Approximate perimeter boundaries, acreage, and topographical features.
5. Proposed location, or alternative locations, of any structures, parking lots, outside storage and landscaping. This may be in the form of a concept layout.
6. Information on proposed public improvements necessary to serve the development. This includes the extension of public streets, sidewalks, storm and sanitary sewers, public transit shelters or any other public amenities.

The above information shall be submitted in narrative and/or graphic format to the Community Development Department; a meeting for the purpose of taking action on the preliminary site plan shall then be conducted within the ten days by the Planning and Zoning Commission. Upon approval of the preliminary site plan, the developer has the assurance that the proposal conforms to the intent of the S-3 MXD District and the proposal shall be permitted. A final site plan shall then be developed and approved in accordance with the Site Plan Review Criteria of the Section 19-2-7(I).

A minimum tract of real estate consisting of eighty acres is required for designation as the S-3 MXD District. A minimum tract of five acres is required for all residential development and nonresidential. An open space buffer 50 feet wide, within which no structure is permitted, is required to separate all nonresidential uses from residential uses. All other dimensional requirements are associated with the respective uses listed in the Residential Districts and M-1 Light Industrial District. These respective Zoning District requirements shall be construed as minimum applicable requirements for development in the S-3 District.
