Any building requiring yard space shall be located at such an elevation that a sloping grade shall be maintained to cause the flow of surface water to run away from the walls of the building.  Grade elevations shall be determined by using the elevation at the center line of the road in front of the lot as the established grade or such grade determined by the Administrator.  When a new building is constructed on a vacant lot between two existing building or adjacent to an existing building, the existing established grade shall be used in determining the grade around the new building and the yard around the new building shall be graded in such a manner as to meet existing grades and not to permit runoff of surface water to flow onto the adjacent property unless the property is part of a natural water course.
