The topography of the site shall be provided at no less than two-foot contour intervals and preferably at one-foot intervals.

The resource protection area shall be accurately shown including all water features identified in the county's Chesapeake Bay Preservation Area Ordinance and the required one-hundred-foot buffer. The exact source of the information used in the delineation shall be noted on the site plan, including the names of any other consulting firms used in determining the limits of all tidal and nontidal wetlands, where present.

2.

Additional review time may be required if the site contains or is in close proximity to sensitive land areas such as floodplain, steep slopes, or resource protection areas; or if the proposed development will exceed the maximum impervious coverage ratio; or as may be deemed necessary by the zoning administrator. In the event additional review time is required, the applicant shall be notified in writing of the additional requirements for approval or reasons for disapproval within ten (10) working days of the submittal date.
