Measure PP. The City Council discussed the implementation options and recommendations identified in the staff report, received public testimony, and provided its direction on the following issues: 1. Methodology for Determining 25-Percent Slope. The City Council defined the calculation of the 25-percent slope as a specific value based on the distance between contour lines on a topographic map. They also clarified that the WIS (Weighted Increment Slope) formula should not be used in the calculation of slope. 2. Methodology for Defining Contour Intervals. The City Council chose two-foot contour intervals. 3. Definition of Ridge and Ridgeline and the 100-Foot Setback. The City Council defined ridgeline as a continuous ground line connecting a series of hills located at their highest elevations ending at the last peak on each end of the landform. The "last peak" would be defined as the point at which the elevation of the ridgeline no longer rises in elevation, and only decreases in elevation. 4. Definition of Streets and Roads as Structures. The City Council concluded that streets and/or roads and their attendant infrastructure are a structure in that they are a physical improvement on the property intended to accommodate development of residential and commercial structures and, therefore, are covered by Measure PP unless the street or road is covered by a Specific Plan or PUD Development Plan approved prior to November 2008. 5. Manufactured (Modified) Slopes over a 25-Percent Grade as amended. The City Council chose determined that modified slopes of 25-percent or greater are covered by Measure PP and are excluded from the developable area of the property, but allowed for the consideration of potential exceptions on a case-by- case basis through the public development review process. The Council directed staff to prepare an amendment to Title 18, the Pleasanton Municipal Code, for the proposed Code Chapter 18.70 on ridgeline and hillside protection and to have the proposed Code Chapter before the Planning Commission in January 2013. Refer to the attached City Council staff report (Attachment #6) and the minutes of the public hearing (Attachment #7) for a detailed description of the discussion at this meeting Planning Commission Public Hearing, January 23, 2013 On January 23, 2013, the Planning Commission opened the public hearing on Chapter 18.70, reviewed the staff report, and received public testimony. After discussion, the Planning Commission continued the public hearing to February 13, 2013 and made the following comments: 1. Consider applying the ridgeline setback to the top of proposed structures rather than the pad elevation of structures. Page 3 of 11
