(C) All drainage provisions shall be of such design to adequately handle the surface runoff and carry it to the nearest suitable outlet such as a curbed street, storm drain or natural watercourse.

(3) Cut and fills shall not endanger adjoining property.
(4) Fill shall not be placed and compacted so as to minimize sliding or erosion of the soil.
(5) Fills shall not encroach on natural watercourses or constructed channels.
(6) Fills placed adjacent to natural watercourses of constructed channels shall have suitable protection against erosion during periods of flooding.
(7) Grading will not be done in such a way so as to divert water onto the property of another land owner without the expressed consent of the Building Commissioner.
(8) During grading operations, necessary measures for dust control will be exercised.
(9) Grading equipment will not be allowed to cross live streams. Provision will be made for the installation of temporary or permanent culverts or bridges.
