Subdivisions shall be planned to take advantage of the existing natural features on the site in a manner which results in an attractive environment and which minimizes grading and the removal of trees and topsoil.
(a) Topography. Subdivisions on land which is relatively flat shall be planned so that streets follow natural drainage courses. On more irregular topography, streets shall generally parallel natural contours to avoid extensive cut and fill. Where practical, lots shall be above street grade. Other standards for grading are set forth in the improvement standards.
(b) Natural Drainage. Subdivisions shall be designed to take advantage of natural contours so that the land can be drained with a minimum of reshaping. Rear lot lines shall be parallel to drainage courses so that, where practical, open drainage courses do not parallel side lot lines. Such restrictions do not apply to enclosed drainage courses. Drainage courses, marshes, and areas which are subject to flooding shall not be utilized as building sites. Other grading and drainage standards are set forth in the improvement standards.
(c) Flood Areas. Due consideration shall be given to any portion of land within a proposed subdivision which is subject to flooding. Such land shall not be platted for development which may increase danger to health, life, or property or which may aggravate flooding (see Chapter 1477 of these Codified Ordinances).
(d) Other Natural Features. Natural features, such as substantial tree cover, waterways, lakes, hills, and open spaces, within a proposed subdivision or related thereto, shall be integrated into the design of the subdivision to obtain natural variety and interest in each neighborhood and the most attractive views possible.
