EC 9.6710 Geological and Geotechnical Analysis Proposed development on properties with slopes equal to or greater than 5% are already subject to geotechnical standards, consistent with South Hills Study policy direction. The proposed amendments to the geotechnical standards update the requirements for geological analysis to address additional factors such as slope, soil types, open drainage ways, and fill. The standards also require the use of a newly adopted Landslide Hazard Map to identify and address potential deep landslide risks. Taken together, the updates raise the bar for developments to consider potential impacts of geological constraints, consistent with South Hills Study policy direction. EC 9.6885 Tree Preservation and Removal Standards The updated tree preservation standards provide a variety of options for compliance and set a higher bar for tree preservation for areas within the South Hills Study area. By raising the required amount of preservation to 50%, rather than 40%, and not allowing mitigation for areas over 900 feet in elevation the updated tree preservation standards demonstrate consideration of the policy intent to protect views in the South Hills Study area. Previously, a tentative PUD applicant utilizing clear and objective standards for property located within the South Hills Study was only required to consider tree preservation. The new tree preservation standards will ensure some preservation as well as provide mitigation for some of the trees to be removed. As such, the proposed standards are better suited to accomplish the policy intent described by the Qbhf!26!pg!32!
