[Ord. No. 530A Art. 3 §1, 11-2-1965]
Whenever the area is divided into lots containing one (1) or more and there are indications that such lots will eventually be resubdivided into smaller building lots, consideration must be given to the highway, street and lot arrangement of the original subdivision so that additional minor streets can be opened which will permit a logical arrangement of smaller lots. Easements providing for the future opening and extension of such streets, may at the discretion of the Board of Aldermen be made a requirement of the plat.
[Ord. No. 530A, Art. 3 §2, 11-2-1965]
The arrangement of highways and streets in new subdivisions shall make provisions for the continuation of the existing highways and major streets (or their proper projection where adjoining property is not subdivided) insofar as they may be deemed necessary by the Board of Aldermen for public requirements. The width of such highways and streets in new subdivisions shall not be less than the minimum street widths established herein. The highway and street arrangements shall also be such as to avoid hardship to owners of adjoining property when they plat their owner land and seek to provide for convenient access to it.
[Ord. No. 530A, Art. 3 §3, 11-2-1965]
When the area to be subdivided adjoins a railroad right-of-way, the intersection of the centerline of any street or highway paralleling the railroad with that of any street that crosses the railroad shall not be less than one hundred fifty (150) feet from the line of the railroad right-of-way.

Vehicular turnaround at the closed end of a street having a minimum radius of fifty (50) feet and a roadway having a minimum radius of forty (40) feet to the interior curb line.
3. 
In the case of temporarily dead-end streets, which are stub streets designed to provide future connection with unsubdivided areas adjoining, the City Planning Commission may require a temporary easement for a turnaround of the nature indicated above, or an appropriate area for a backaround, or a roadway at least twenty-six (26) feet in width of not excessive length to connect the temporary dead-end with an existing street.
[Ord. No. 530A, Art. 3 §7, 11-2-1965]

B. 
Gutter grades on paved gutters shall not be less than one-half (½) of one percent (1%).
C. 
All changes in street grades shall be connected by a vertical curve of reasonable length to assure adequate visibility.
D.

A. 
Street intersections shall be rounded by radii of at least twelve (12) feet.

[Ord. No. 530A Art. 3, §9, 11-2-1965]

Corner lots shall have extra width sufficient to permit the establishment of front building lines on both adjoining streets.

[Ord. No. 530A, Art. 3 §14, 11-2-1965]
The City Planning Commission and Board of Aldermen may require that certain minimum regulations regarding type and character of development be incorporated in the owner's declaration of plat. Such regulations shall be intended to protect the character and development of the platted subdivision, as well as that of the surrounding development.
[Ord. No. 530A, Art. 3 §15, 11-2-1965]
Where alleys are not provided in the plat, easements of not less than five (5) feet in width shall be granted to the City by the owner on each side of all rear lot lines and where necessary side lot lines for public utility requirements.

Where an area being subdivided includes lands proposed to be used for parks or schools, the subdivider shall indicate the location of such area on the subdivision plat. Park sites are to be purchased within one (1) year of the recording date of the subdivision by the City at the appraised raw land value prior to subdivision plus one-half of the cost of grading and paving, including curbs, of the portion of any streets that are contiguous to the site.
