The design of the proposed park shall generally avoid any features that would Prior to PUD Development require removal of the existing cover or excavation into the landfill materials. Plan approval of Lot 14. Should excavation into the landfill materials be required (e.g., for utilities or building foundations), the excavations shall be made under a worker health and safety plan prepared by a Certified Industrial Hygienist. All development projects on lands adjacent to the landfill on Lot 14 shall Prior to PUD Development conduct a gas survey to determine if significant gas migration from the landfill Plan approval' for affected is affecting the development site. The results of the survey shall be used to properties. Vineyard Avenue Corridor Specific Plan Draft EIR MMP-16 Mitigation Monitoring Plan
