§ 157.039  RESIDENTIAL, MIXED USE (R-3).
   (A)   Purpose and intent. The purpose of this District is to encourage innovative and flexible development design that will create and promote a sustainable and harmonious community. It is the intent of the District to promote more economical and efficient use of the land while encouraging variety in housing choices, neighborhood commercial uses, and accessory light industrial areas, while at the same time, maintaining the greatest amount of open area that results in the least disturbance to natural features. The guidelines for this District shall be implemented by approval of an overall Master Plan of development.
   (B)   Permitted uses. The Residential, Mixed Use District is devoted to diverse uses that contribute to a coordinated balance of activities which encourage and promote a suitable environment for family life and potentially provides convenience shopping and job opportunities within a planned community. The primary uses are residential in nature as follows:
      (1)   Single-family detached or attached dwellings;
      (2)   Two-family dwellings;
      (3)   Multifamily dwellings which may include apartments, townhouses, condominiums, or similar development that provides more than two dwelling units per building;
      (4)   Accessory structures as defined;
      (5)   Facilities necessary for rendering local public utility service. Buildings, treatment plants, water storage tanks, pumping or regulating stations, storage yards and substations, county sanctioned recycling centers and refuse collection centers shall be considered as part of the Master Plan for development. Underground utility service shall be required except where shown to be not feasible;
      (6)   Community recreation uses, including clubhouses, golf courses, pools, tennis courts, boating facilities, and similar recreational improvements and facilities; and/or
      (7)   Manufactured home park.
   (C)   Secondary uses. Secondary uses allowed that provide a higher level of amenities and community features. These uses are permitted to accompany the residential uses and the provisions of this section are not intended for creation of areas primarily devoted to these secondary uses:
      (1)   Churches;
      (2)   Schools;
      (3)   Childcare or day care center, including preschool classes;
      (4)   Business uses provided that such businesses are designed to serve primarily the needs of the planned development in which they are located. Business uses and associated off-street parking and loading areas shall not exceed 5% of the gross area of the planned development; and/or
      (5)   Industrial uses that are designed to provide jobs primarily for residents within the planned development. These industrial areas shall be allowed if shown to be compatible with the character and scope of the planned development and shall not exceed 5% of the gross area of the planned development.
   (D)   Area, bulk, and density requirements.
      (1)   The permitted overall size of any Residential, Mixed Use Development shall be considered as part of the Master Plan approval for the development.
      (2)   The permitted height of the buildings and required setbacks from property lines and required distances between structures within a Residential, Mixed Use Development shall be determined as part of the Master Plan approval. The preliminary site plan shall include an accurate accounting of the proposed building locations, heights, setbacks, and separations.
      (3)   The maximum density of a Residential, Mixed Use Development shall not exceed an average of one dwelling unit per gross acre. Land devoted to business, industrial, and other nonresidential uses shall not be included to determine the density ratio for the development as a whole. The Board of Supervisors may permit an increase in the density of the development when it can be demonstrated that such an increase is warranted by conditions specifically applicable to the parcel or plan of development; provided, that such increase will not have any adverse impact on the character of the surrounding property, cause any potential health or safety hazards, or generate traffic that will be excessive for adjoining streets.
      (4)   No minimum lot size restriction shall be placed on development with the Residential, Mixed Use District. This flexibility is offered to encourage innovative site designs that are in accord with the District’s intent of promoting efficient use of land, variety in housing choices, higher levels of amenities, and preservation of open spaces and natural features.
   (E)   General standards.
      (1)   The Residential, Mixed Use Development shall conform to the goals, objectives, and policies of the adopted County Comprehensive Plan.

      (3)   The Residential, Mixed Use Development shall efficiently utilize the available land and shall protect and preserve to the extent possible all scenic assets and natural features such as trees, streams, and topographic features.
      (4)   The Residential, Mixed Use Development shall be designed to minimize injury to the use or value of existing surrounding property, and shall not hinder, deter, or impede the use or development of surrounding properties in accordance with the adopted Comprehensive Plan.
