F-shiblt A <br />South Hills study <br />Purpose Statements and Recommendations <br />Page S <br />2. To encourage preservation as open space those areas characterized <br />by <br />a. Intermediate and steep slopes; <br />b. Higher elevations; <br />c. Significant amounts of vegetation; <br />d- Significant visual impact. <br />That adequate review of both on-site and off-site impact of any develop- <br />ment by a qualified engineering geologist occc-ar under any of the following <br />conditions: <br />1. All formations <br />Soil depth of 40 inches and above <br />Slopes of 30 percent and above <br />2. Basalt flows <br />Soil depth of 40 inches and above <br />Slopes of 20 percent to 30 percent <br />3. Eugene Formation <br />Soil depth of 40 inches and above <br />Slopes of 20 percent to 30 percent <br />4. Basalt flows <br />Soil depth of 20 to 40 inches <br />Slopes of 30 percent and above <br />S. Eugene Formation <br />Soil depth of 20 inches to 40 inches <br />Slopes of 30 percent and. above <br />That developments be reviewed to encourage clustering of open space ele- <br />ments of different developments in order to preserve the maximum amount <br />of continuous open space. <br />That developments be reviewed iu terms of scale, bulk and height to in- <br />sure that development blends with rather than dominates the natural <br />characteristics of the south hills area. <br />That all proposed road locations be reviewed to insure minimum grade <br />disturbance and minimum cut-and-fill activity, particularly in those <br />areas most visible due to slope, topographic or other conditions. <br />That planned unit development review shall be based upon a recognition <br />of both public and private interest. In areas of significant conflict <br />(e.g., locating development in a highly visible area as opposed to a <br />less visible area or in an area of significant vegetation as opposed <br />to a relatively open area) which could be resolved through use of an <br />alternative development plan, primacy shall be given to the public <br />interest in ally determinations. <br />
