§ 197-1 Required report.

No proposed street or part thereof shall be accepted by the City until there has been submitted to the City Council a report by the City Planning Board and the Director of Public Works that there is a public need for such street and that said street shall conform in a harmonious relationship to the future development of the City.

§ 197-2 Payment of initial cost; guaranties.

No street shall be accepted by the City Council until the person or persons requesting the acceptance pay the total cost of the initial improvement of grading and graveling the street to a cross section and grade approved by the Director of Public Works and guarantee to reimburse the City for such costs within such time as the Council shall limit and post a corporate bond certified by the City Solicitor as valid and enforceable by the City, in the amount and with surety satisfactory to the City Council.

§ 197-3 General requirements.

Applications by the owner or his authorized representative for the acceptance of a street by the City shall be made, in writing, to the City Council, along with a plan of the street. The plan of the street shall be such as to meet the minimum requirements as detailed herein and shall be approved by the Director of Public Works.

§ 197-4 Conformance with existing street system.

A. 
The streets on all plans submitted shall be in harmony and coordination with the existing street system of the City.
B. 
Where the herein specified minimum widths may be impracticable, such as in the continuation of some existing streets, the extension shall be of a width at least as great as that of such existing streets.
C. 
Where a plan is now on file and has been approved by the Director of Public Works but the street or streets on said plan have not been formally accepted by the City, then the plan widths of said street or streets shall govern.
D. 
Where the plan emitted covers only a part of the applicant's tract, a sketch of the prospective street system of the unsubmitted part shall be furnished so that the street system of the part submitted may be considered in the light of adjustments and connections with the street system of the part not submitted.

§ 197-5 Access.

The street or streets on any plan submitted shall have satisfactory access to an existing public street or public highway, with no reserve strips controlling this access, except where the control of such strips is definitely placed in the authority of the City under conditions approved by the City Council.

§ 197-6 Street width.

A. 
The minimum width for a street shall be 50 feet. This width shall be measured from lot line to lot line.
B. 
The requirement for width may be modified by the Director of Public Works when the topography or other physical conditions make a street of the required width impracticable or when, in his opinion, the street in question should exceed the minimum width required.

§ 197-7 Rounding street corners.

Wherever necessary to permit the construction of curbs having a minimum radius of 25 feet at the street corners without curtailing the sidewalk to less than normal width, the property line at such street corner shall be rounded or otherwise set back sufficiently to permit such construction. Normally, the radius of the property line shall be not less than 10 feet. Larger radii may be required by the Director of Public Works when, in his opinion, such design is advisable.

§ 197-8 Culs-de-sac.

Streets designed to have one end permanently closed (culs-de-sac) shall be provided at the closed end with a turnaround roadway having a minimum radius for the outside curve of at least 60 feet.

§ 197-9 Street grades.

A. 
Street grades shall not exceed 10% nor be less than 1%.
B. 
Variation from these may, however, be permitted by the Director of Public Works where advisable to adjust to topographical conditions.

§ 197-10 Angles of intersection.

As far as practicable, acute angles between streets at their intersections are to be avoided, and where a deflection angle of more than 10° in a street line occurs at any point on the street, a curve of reasonable long radius is to be introduced.

§ 197-11 Monuments.

Monuments shall be placed on the side lines of the street at all angle points, all points of curvature and at such intermediated points as shall be required by the Director of Public Works or at related points approved by the Director of Public Works. The monuments shall be of such material, size and length as may be fixed as a standard by or approved by the Director of Public Works.
