• The project developer shall undertake a detailed, design-level geotechnical in- visitation and, based upon this investigation, shall submit adesign-level report with the tentative subdivision map that incorporates and further develops the conclusions and recommendations of the existing planning/development level geotechnical report and the comments and recommendations provided by the City's peer review geologist/geotechnical engineer. The report shall be subject to the review and approval by the City Engineer before the Planning Commission's action on the tentative subdivision map. • To ensure that existing landslides are properly identified, repaired, and areas of unstable soils are stabilized, the report shall evaluate each lot for geotechnical suitability. If unstable soils and/or slopes could affect areas within designated lot boundaries, these areas shall be clearly demarcated on an engineering geologic map and repaired prior to issuance of building permits. • The project developer shall arrange and pay for a geotechnical engineer to inspect and approve all subdivision improvements including, but not limited to, retaining walls, drainage improvements, geotechnical mitigations, etc., during construction to ensure that the recommendations have been properly incorporated into the development. The geotechnical engineer shall be present on site during grading and excavation operations. The results of the inspections and the as-built conditions of the project shall be certified in writing by the geotechnical consultant for conformance to the approved plans and geotechnical report and shall be submitted to the City Engineer for review and approval prior to the sale of the lots. • The lot-specific building developer shall arrange and pay for a geotechnical engineer to inspect and approve all building site improvements including, but not limited to, foundations, retaining walls, drainage improvements, geotechnical mitigations, etc., during construction to ensure that the recommendations have been properly incorporated into the development. The geotechnical engineer shall be present on site during grading, excavation, and construction operations. The results of the inspections and the as-built conditions of the project shall be certified in writing by the geotechnical consultant for conformance to the approved plans and geotechnical report and shall be submitted to the Chief Building Official for review and approval prior to the inspection. This statement shall appear in the design guidelines. • The project developer shall create a Geologic Hazard Abatement District (GRAD) for the development covered by this approval. The project developer shall be responsible for preparing all necessary documentation to create the GRAD, including any expenses incurred by the geotechnical engineer for the preparation of the GRAD. The developed project site -privately-owned and City-owned - shall be maintained through an ongoing Slope Management Program (SMP) and a Plan of Control (POC), administered by the GRAD. The project developer shall Exhibit A Page 28 of 45 Ordinance No. 1961 PUD-33, Oak Grove
