(i) Subdivisions shall be planned to take advantage of natural features, which will result in an attractive environment and minimize required construction of storm water management facilities and controls, utilities, grading and removal of trees and topsoil. Streets shall follow natural drainage courses where appropriate. On irregular topography, streets shall parallel contours to avoid extensive cut and fill. In so far as possible, lots shall be above street grade. Subdivisions shall be designed to take advantage of natural contours so that all of the land can be drained with a minimum of reshaping. In so far as possible, open drainage courses shall not parallel side lot lines. Where a proposed subdivision includes a natural lake or pond, or a lake or pond will be created in such subdivision, the Commission may require the installation of hydrant connections to such body of water where, in the opinion of the Commission, such connections shall substantially benefit the health or safety of the inhabitants of such subdivision. Natural features, such as substantial tree cover, water courses, lakes, hills and open space within a proposed subdivision shall be integrated into its design to obtain natural variety and interest in each neighborhood and the most attractive view as possible. Whenever possible, natural conditions such as ponds, creeks, lakes, marshes, streams, watercourses or wetlands shall be preserved. Where property proposed to be subdivided is indicated to be wetlands or streams within the jurisdiction of the United States Army Corps of Engineers, or the Ohio Environmental Protection Agency, the Commission may require adequate proof of compliance by the developer with Federal or State Wetland Laws, Rules and Regulations including verification of issuance of Sections 401 and 404 Certificates from the appropriate governmental agencies.
