or the subject parcel alone, it complies with WORGO 25-28.7a.1. The various slopes by percentage are colored coded for this lot. However, the topography does not extend 200 feet in all directions from the subject parcel. This is important to identify any of the features depicted on Exhibit A of the Ordinance. These features which are defined in the Ordinance are known as the “Cliff Line (or Cliff Face)” and “Rock Cut”. Per the Ordinance, the proximity of these features to the subject parcel may reduce the effective area of the lot as areas with 100 feet of each are considered non-developable. Additionally, areas within 100 feet of each may not be disturbed. The Steep Slope Disturbance Exhibit must locate these features with respect to this parcel. In addition to the areas described above which may not be disturbed, areas where the slope of the parcel that exceed 25 percent in grade too shall not be disturbed.
