Topographic contours to one foot shall be indicated thereon. The plan shall show the method to be used for adequate disposal of all storm sewer water, including drainage outlets, and shall include a typical lot cross section drawn perpendicular to the street indicating lot grading and such other data as may be required by the Village Engineer. Such plan shall be drawn at a scale not less than 50 feet to the inch. (Ord. 2019-4. Passed 10-14-19.)
