Whenever, in the judgment of the Chief Building Official or Public Works Director, in consultation with an expert such as a soils or geotechnical engineer, construction operations will result in slopes so steep that their stability may be in question, the Chief Building Official may require retaining walls or other slope stabilization measures. These shall be made adequate to the satisfaction of the Chief Building Official. Design by a registered engineer or licensed architect may be required. (Ord. 1069 § 5, 2023; Ord. 1062 § 5, 2022)
