(a) Cut and fill slopes shall not result in a finished slope steeper than four (4) horizontal to one (1) vertical (4:1). If a request is made for a cut or fill slope steeper than 4:1, the applicant must obtain an opinion in writing from a qualified geotechnical engineer that the materials are capable of standing on steeper slope without creating a hazard. This opinion must be forwarded to the City Engineer for review and approval before the start of the cut and/or fill construction.
(b) If, in the opinion of the City Engineer, any cut slope exhibits the existence of inclined strata or fault, or any fill slope exhibits any of the conditions indicated under Section ST 806 of the Rules and Regulations Governing the Construction, Operation and Maintenance of the Hamilton County Storm Water Drainage System dated August 17, 1996. he may require the developer to furnish a report and recommendation from a qualified geotechnical engineer as to the probability of landsliding or other instability, and as to preventive measures required. If the developer fails to follow such recommendations, the City Engineer shall declare the land affected to be unfit for human habitation, and shall so advise the Planning Commission.
