(A) An adequate storm drainage system shall be designed in accordance with Chapter 154 of this code of ordinances.
(B) (1) There shall be submitted for approval by the Village Engineer, at the time of final plat approval, a lot grading and foundation elevation plan. It shall show at each lot corner the proposed U.S.G.S. elevation for that point. Arrows drawn along all lot lines shall show the direction of drainage flow. The top of the foundation shall be shown by a U.S.G.S. elevation. That elevation shall be noted inside the symbol for the structure location on the lot.
(2) Where there is more than one foundation level for the structure, the elevation for the lowest foundation level shall be shown. The foundation elevation shall be such that the lot drainage be designed to run away from the top of the foundation. In the event that conditions dictate that some parts of the lot be higher than the structure foundation, the grading plan will show specific drainage configurations for the lot specifying that all drainage is directed away from the foundation.
