No permit shall be issued for an excavation or fill to be made with a face steeper in slope than three horizontal to one vertical, except that the Building Commissioner may permit an excavation or fill to be made with a steeper face if an applicant demonstrates satisfactorily, by means of appropriate soil exploration and analysis and the written opinion of a geotechnical engineer, that the materials are capable of standing on a steeper slope without creating any of the hazards described in §§ 1464.03 and 1464.04.
