A. Whenever a tract to be subdivided embraces any part of a street designated in the adopted transportation plan, the streets shall be platted in conformance therewith.
B. Whenever a tract to be subdivided is located within an area for which a specific plan has been approved by the Planning Commission , the street arrangement shall conform substantially to the plan.
C. Certain proposed streets, as designated by the City Engineer, shall be extended to the tract boundary to provide future connection with adjoining unplatted lands.
D. Local streets shall be so arranged as to discourage their use by through traffic.
E. Where a proposed subdivision abuts or contains an existing proposed parkway, the City Engineer may require marginal-access streets or double-frontage with nonaccess easements along the parkway, or such other treatment as may be justified for protection of residential properties from the nuisance and hazard of high volume traffic, and to preserve the traffic function of the arterial route.
F. Where a subdivision abuts or contains the right-of-way of a railroad, a limited-access high-way, an irrigation canal, or abuts a commercial or industrial land use, the City Engineer may recommend location of a street approximately parallel to and on each side of the right-of-way at a distance suitable for appropriate use of the intervening land. The distance shall be determined with due regard for approach grades, drainage, bridges or future grade separations.
G. Streets shall be so arranged in relation to existing topography as to produce desirable lots of maximum utility and streets of reasonable gradient, and to facilitate adequate drainage.
H. Alleys shall be required in all multifamily residential, commercial and industrial subdivisions, except that the City Engineer may recommend waiver of this requirement in certain residential districts because of topography, required lot size or in lieu of underground utilities. The City Engineer may also recommend the waiver of the requirements in industrial subdivisions.
I. Half streets shall be discouraged except where necessary to provide right-of-way required by the transportation plan to complete a street pattern already begun or to ensure reasonable development of a number of adjoining parcels. Where there exists a platted half street abutting the tract to be subdivided and the half street furnishes the sole access to residential lots, the remaining half shall be platted within the tract.
