(6) Provision for surface water disposal, ponding, drainage, and flood control;
(7) Complete topographic map with contour intervals not greater than two feet, water courses, marshes, rock outcrops, and other significant features, all superimposed on at least one print of preliminary plat. United States Geodetic Survey datum shall be used for all topographic mapping. High water elevation and date thereof if parts of plat are wet or have been wet. In the case of a subdivision where no new street is involved, the required topographic map may be waived if it is deemed unnecessary by the City Engineer and the City Council;
(8) Where structures are to be placed on large or excessively deep lots which are subject to potential replat, the preliminary plat shall indicate a logical way in which the lots could possibly be resubdivided in the future;
(9) A plan for soil erosion and sediment control both during construction and after development has been completed. The plan shall include gradients of water-ways, design of velocity and erosion control measures, design of sediment control measures, and landscaping of the erosion and sediment control system;
(10) All vegetation preservation and protection plan that shows those trees proposed to be removed, those to remain, the types and locations of trees, and other vegetation that are to be planted;
