(a) Intent. The intent of the "PD-O" Planned Development – Office District regulations is to:
(1) Provide for and recognize that many office establishments seek to develop within unified groupings, usually under single ownership and control, and typically called "office centers or office parks";
(2) Achieve harmoniously designed structures upon a well landscaped site, achieving a high degree of pedestrian-vehicular separation, all of which would be compatible with surrounding land uses;
(3) Assure such groupings would have all necessary services and facilities comprehensively provided in accordance with an approved development plan; and
(4) Encourage and preserve opportunities for energy efficient development.
