(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 1183.
(b) However, when a fence or wall is proposed at a separate time from any other development for new construction, additions or site renovation, a fence or wall may be approved administratively by the Zoning Administrator when the Zoning Administrator determines that the proposal:
(1) Complies with the requirements of this Section;
(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.
If, because of the nature and location of the proposed fence or wall, the Zoning Administrator does not make such a determination, the request shall be referred to the Planning Commission and considered by the Commission according to the development plan procedures in Chapter 1183.
