Upon the determination by the Zoning Administrator and the Planning Director, with the concurrence of all appropriate agencies, a simplified site plan may be filed by the owner/occupant of a proposed single-family detached dwelling, an accessory building, a temporary use, an addition to or change of use for a commercial or industrial structure or for a special exception use which does not require a building permit in those cases where a field inspection indicates that the scope of the proposed accessory building, addition or special exception use is of such nature that the provisions for the handling of natural and storm water, sediment control, off-street parking, setbacks, water and sewerage and other requirements can be adequately addressed with a simplified site plan. Said site plan may be approved by the Zoning Administrator and the Planning Director upon concurrence of all appropriate agencies, except that approval of industrial use site plans shall be in accordance with other sections of this chapter.
