§ 158.081 EC EMPLOYMENT CAMPUS DISTRICT.

   (A)   Purpose and intent. The purpose of the EC District is to provide for and foster comprehensively planned employment centers in campus-like settings to attract employers of highly skilled workers and primarily higher paying jobs, including but not limited to research and development, institutional, office, flex space, and other light and limited industrial uses, while also providing a more flexible approach to design and development. In this district, the integration of trails, sidewalks, communal plazas, and share amenities is encouraged. An EC development may be comprised of multiple contiguous lots, the extent of which shall be depicted on individual site plans. The following objectives are sought in providing for the EC District:

      (6)   To ensure that the limited number of permitted and accessory residential, retail, service, eating and drinking uses within the district have the principal purpose of serving the employment campus;
      (7)   To encourage green spaces, walking trails and other recreational uses;
      (8)   To serve as an economic development tool in the effort to increase the county’s commercial and industrial tax base;
      (9)   To encourage development of buildings that can be easily adapted as the range of tenants and regional market for employment evolves; and
      (10)   To provide a flexible employment district.
