(A) Prior to any grading or improvement on the land of the proposed subdivision, 4 copies of a preliminary plat drawn to scale by a licensed engineer or surveyor shall be submitted to the planning commission showing all lots, streets, existing and proposed storm and sanitary sewers and water mains, topography with one-foot contours, and other pertinent data, together with typewritten copies of the proposed restrictions, and such preliminary plans and specifications for the construction of the improvements required by these regulations or ordinances as may be required by the city engineer or his authorized representative; provided, however, that the contour lines on the preliminary plat may represent differences in elevation of 2 or more feet if authorized or approved by the city engineer.
(B) One copy of the preliminary plat, restrictions, and plans will be referred by the planning commission to the city engineer or his authorized representative, if the land is in the city, and to the county engineer if the land is outside the city, for examination and recommendations with special reference to the topographical location of lots and streets, and to necessary culverts, ditches, storm sewers, or drains both on streets and on natural watercourses through lots. No plat will be approved unless provision is made for adequate drainage of both streets and lots.
(C) Conditional approval of the preliminary plat, with such changes as have been agreed upon by the planning commission and the subdivider, will be given by the commission if such plat and changes are in accordance with these rules and city ordinances.
