05/08/2017 All equipment used for the removal of French broom or other invasive plants shall be cleaned before being used at another, non -infested part of the site. Finding: Implementation of Mitigations BIO -4, BI0-5 and BI0-6 would reduce the project - related impact to trees and the potential spread of invasive, non-native plants on the site during construction to a less than significant level. Facts in Support of Finding: These mitigation measures are consistent with best management practice to protect and replace trees impacted during construction and prevent the spread of invasive non-native plants on the site. Tree protection measures will be under the direction of the City Landscape Architect and equipment is required to be cleaned before use in another part of the site to prevent the spread of invasive plants. Replacement trees are required to be replaced at a ratio of three new trees for each native tree removed and one new tree for each non-native tree removed and the replacement planting shall be limited to native plants. The replacement trees are required to be planted within 12 -months of project completion. These measures will ensure the site is replanted with sufficient native plantings to mitigate the removal of existing trees. Geologv and Soils Impact: GEO-1: Construction may impact slope stability for both temporary cuts slopes during construction and the long-term stability of the permanent cut slopes under seismic conditions. Mitigation: GEO-1: Prepare a detailed geotechnical report to address slope stability and follow the geotechnical engineer's recommendations in the design of the project to achieve acceptable factors of safety under seismic conditions. Finding: Implementation of Mitigation GEO-1 would reduce the project related construction and long-term stability of slopes to a less than significant level. Facts in Support of Finding: The geotechnical report will evaluate the hillside soil conditions and provide detailed engineering recommendations to address slope stability during construction and throughout the life of the project. The evaluation will also recommend measures for the retaining walls to withstand saturated soil conditions on a steep hillside. Implementing the recommendations of the geotechnical report will reduce the potential impact associated with development in the hillside. Hazards and Hazardous Materials Impact: HAZ-1: The use or accidental release of hazardous materials at the project site could expose the public or environment to significant hazards. Mitigations: HAZ-1: The following measures, as listed in the ProTech Consulting & Engineering report titled Pre-Demolition/Renovation Asbestos & Lead Survey & Evaluation, shall be implemented during demolition activities associated with the existing pump station: Prior to demolition, the loose and peeling exterior Lead Based Paint shall be Page 7 of 28 ATTY/ RESO.0043/CC RESO HILLSIDE ALTERNATIVE PROJECT RESO.
