(a) The location of proposed landscaping, fences, or walls required to fulfill the standards and criteria of this Chapter shall be reviewed and approved as part of a development plan pursuant to Chapter 1127.
(b) However, when a fence, wall, or landscaping is proposed at a separate time from any other development for new construction, additions or site renovation, a fence, wall, or landscaping may be approved administratively by the Zoning Administrator when the Zoning Administrator determines that the proposal:
(1) Complies with the requirements of this Chapter and other applicable provisions in this Development Code;
(2) Is consistent with any previously approved plan;
(3) Is compatible with the current site development if there is no approved plan; and,
(4) Will have a minimal adverse impact to the surrounding areas.
