Care shall be exercised in this design and laying out of streets, lots and other elements that good planning principles are followed, efficient use is made of land and that natural assets such as trees and topography be retained wherever practical.
[Ord. No. 1007 §16-303.02, 1-24-2001; Ord. No. 1091 §§1 — 3(App. A §455.110), 9-24-2003]
Subdivision proposals shall be designed to assure that all such proposals are consistent with the need to minimize flood damage, that all public utilities and facilities, such as sewer, gas, electrical and water systems, are located, elevated and constructed to minimize or eliminate flood damage and that adequate drainage is provided so as to reduce exposure to flood hazards. Subdivisions shall be designed in accordance with standards established in Sections 455.270 et seq.
[Ord. No. 1007 §16-303.03, 1-24-2001; Ord. No. 1091 §§1 — 3(App. A §455.120), 9-24-2003]

B. 
Proposed streets must conform to existing topography as nearly as possible in order that drainage problems may be reduced. Surface drainage across residential lots or along the side or rear lot lines shall be avoided wherever practical. Where such surface drainage on residential lots is necessary, easements shall be provided and the City may require installation of pipe, masonry or rip-rap flumes or such other protective devices in order that adjacent or surrounding property or the welfare of the public shall not be endangered and maintenance will be kept at a minimum.
