BACKGROUND Purpose The purpose of this workshop is to request the City Council's input on the implementation of Measure PP, specifically the following items: 1) how to measure slopes, 2) the definition of ridge and ridgeline, and 3) whether the construction limitations on slopes 25 percent or greater apply to manmade slopes or roadways. This report describes implementation options on each issue and a staff recommended option for consideration by the City Council. Staff proposes that the options selected by the City Council be incorporated into a new Chapter of the Zoning Ordinance (Title 18) that provides comprehensive direction on the implementation of Measure PP. This code amendment would be brought forward in January 2013. Measure PP limitations to the development of hillside properties shall apply in conjunction with the ongoing requirements of City, State, and Federal regulations addressing ridgeline protection, protection of jurisdictional waters and habitat areas, trees, wildland fire mitigation, urban stormwater runoff treatment and necessary mitigation identified in individual project review. Measure PP In November 2008, Pleasanton voters passed Measure PP, the "Save Pleasanton's Hills & Housing Cap Initiative." Measure PP states, in part: "No grading to construct residential or commercial structures shall occur on hillside slopes 25% or greater, or within 100 vertical feet of a ridgeline." Measure PP amended the City's General Plan adding a land use policy that addresses the location of commercial and residential structures on the City's hillside areas with respect to slopes and ridges. However, it did not define the terms slope, ridge and ridgeline, or structures, nor did it address the streets or roads covered by previous City approved Specific Plans and/or PUD developments located on hillside areas with a 25- percent or greater slope, and the treatment of manufactured slopes of 25-percent or greater. Attached is the "Analysis of the Impacts and Effects of the Save Pleasanton's Hills & Housing Cap Initiative" with a copy of Measure PP, dated June 11, 2008 (Attachment 1), and copies of the minutes of the May 20, 2008, June 26, 2008, and July 15, 2008 City Council public hearings (Attachment 2) on Measure PP.
