(1) All operations shall be conducted in accordance with the performance standards specified in this chapter.
(2) No excavation or stacking or stockpiling of material shall be permitted nearer than 50 feet to the boundary of an adjoining property or to a public street.
(3) No excavation shall be made with a cut steeper than one horizontal to one vertical, nor shall fills be made with slope steeper than two horizontal to one vertical, except as follows:
(a) Slopes less steep may be required if there is evidence that conditions necessitate such slopes for stability or safety.
(b) Steeper slopes may be permitted; provided, that a written report is submitted by a competent soil engineer or geologist stating that he has investigated the proposed operation, made adequate tests and calculations, resulting in his conclusion as to the degree of cut and/or fill slopes which may be constructed without endangering the safety of persons or property.
