The City Council may, at its discretion, reduce the required buffer under the following conditions:
1. In those areas where the boundary line abuts permanent natural features that function as a buffer, including, but not limited to, ponds, severe grades, or mature woodlands, requirements for a buffer area for that portion of the boundary may be reduced by the City Council in the proportions that the permanent natural features fulfill the buffer requirements.
2. In those areas where the property abuts an undeveloped property that is shown on the adopted land use plan as the same or a more intensive use.
3. The abutting property has provided a portion or the entire required buffer.
4. On lots that can present evidence that the above buffer provisions would render the property unbuildable, the City Council may grant a waiver of the buffer requirements and permit a fence of not less than six feet in height. Provisions for landscaping to soften the visual appearance of the fence and provide additional buffering may be required and will be reviewed on a case-by-case basis.
5. In those areas that abut a public park, the buffer area for that portion of the boundary may be reduced to 50 percent of the requirement.
