Each block of a subdivision, or part thereof, shall be planned and graded so that the surface water of each lot will not be discharged on to adjoining lots and will drain onto a street, into a storm sewer system or into a natural drainage way. The grading of streets shall extend to the full width of the right-of-way. Tree lawns shall be sloped at a gradient of not less than 2% or more than 3% toward the pavement. Sections which are in cut shall not exceed a ratio of 2:1, and sections which are in fill shall not exceed a ratio of 4:1 within the lot area. Where necessary, grading may be extended into lot areas to provide suitable house sites. Topsoil shall be stripped from all graded areas and replaced to a depth of four inches after completion. Tree lawns, turf gutters and other graded areas shall be fertilized, seeded and mulched or otherwise protected against erosion and to assure the proper growth of the turf.
