the long axis of the ridge." This latter definition is useful in the Southeast Hills, which is <br /> characterized by long ridgelines running in a generally northerly or northwesterly <br /> direction. While the long ridgelines in the Southeast Hills seem to obviously meet the <br /> definition of the landform, many ridges contain short "spurs" that extend in a <br /> perpendicular fashion off the main ridge. These spurs, likely created by two parallel <br /> drainages flowing down the side of the ridge from the ridgeline, typically fall steeply to the <br /> valley floor. If portions of these spurs fell within the horizontal area already encompassed <br /> within the 100-foot vertical setback (and exhibited the drainage-derived topography <br /> described above), they were not considered ridgelines. This approach eliminated from <br /> Measure PP spurs and secondary ridges subservient to the main ridgelines (see Figures <br /> 3 and 4 for examples of ridgelines and spurs). <br /> Figure 2: Slopes on Longview Drive <br /> Percent Slope -17-22% -12-22% -5-13% -4-7% <br /> r vi,,,,, <br /> .. r - `� <br /> . _, <br /> ,.. ii ... <br /> yyy <br /> ,. - nea 1,- IL , i ,,,, , <br /> fah` _ Ci' ! r <br /> a G �_ rt t it'•s <br /> - .. ,,_ '- , \rs,•:" : <br /> : ..c4i IA ..,, ..._+ e• <br /> iti.,.. :': I- lit 7 <br /> r- r r <br /> Mapping of Southeast Hills Planning Commission <br /> Page 6 of 10 <br />
