Dwelling mix. Throughout the entire community, a minimum of two residential uses and/or configurations of single-family attached dwellings, as defined in §
300-325A herein, shall be required. Within at least one of those uses/configurations, a minimum of two distinctly different architectural styles shall be required. With the exception of the minimum percentage for single-family detached units of 10%, as stipulated in §
300-325A(1) herein, there shall be no minimum percentage for any proposed residential use or configuration of single-family attached dwellings. Dwelling unit mix requirements need not be enforced if all dwelling units throughout the community are proposed as age-restricted adult units. The Board of Supervisors may grant modifications from the specific mix requirements herein, provided that the spirit and intent of this article and the statement of community development objectives contained in §
300-2 are observed, and that the overall density specified in §
300-328A herein is not exceeded. Any such variations shall be embodied in the development agreement specified in §
300-327D herein and reflected on the master plan required in §
300-331 herein. Such modifications may be made at the time of initial development plan approval for the entire community, or may be requested and granted at subsequent times as a result of market changes; any subsequent modifications shall be reflected in amendments to the development agreement and master plan.
