All lots where fill material is deposited shall have clean fill or topsoil deposited which shall be graded to allow complete surface drainage of the lot into local storm sewer systems or natural drainage courses. No regrading of a lot shall be permitted which would create or aggravate water stagnation or a drainage problem on site or on adjacent properties, or which will violate the provisions regulating soil erosion and sediment control, soil removal or flood plain contained in this section and other applicable State regulations. Any topsoil disturbed during approved excavation and grading operation shall be redistributed throughout the site.
