The subdivider shall observe the following requirements and principles of land subdivision in the design of each subdivision or portion thereof.
The subdivision plat shall conform to design standards that will encourage good development patterns within the borough. Where either or both an Official Map or Master Plan has or have been adopted, subdivision shall conform to the proposals and conditions shown thereon. The streets, drainage rights-of-way, school sites, public parks and playgrounds shown on an officially adopted Master Plan or Official Map shall be considered in approval of subdivision plats. Where no Master Plan or Official Map exists, streets and drainage rights-of-way shall be shown on the final plat in accordance with the revised statutes of New Jersey, N.J.S.A. 40:55-1.20, and shall be such as to lend themselves to the harmonious development of the borough and enhance the public welfare in accordance with the following design standards.
A. 
The arrangement of streets not shown on the Master Plan or Official Map shall be such as to provide for the appropriate extension of existing streets.
B. 
Subdivisions abutting arterial streets shall provide a marginal service road or reverse frontage with a buffer strip for planting, or some other means of separation of through and local traffic as the Planning Board may determine appropriate.
C. 
The right-of-way width shall be measured from lot line to lot line and shall not be less than 50 feet.
D. 
No subdivision showing reserve strips controlling access to streets shall be approved except where the control and disposal of land comprising such strips has been placed in the Borough Council under conditions approved by the Planning Board.
E. 
Subdivisions that adjoin or include existing streets that do not conform to widths as shown on the Master Plan or Official Map or the street width requirements of this chapter shall dedicate additional width along either one or both sides of the road. If the subdivision is along one side only, 1/2 of the required extra width shall be dedicated.
F. 
Grades on all streets within any subdivision shall not in any case exceed 10%. No street shall have a minimum grade of less than 1%; within 50 feet of the intersection of any street the maximum shall be limited to 2%.
G. 
Street intersections shall be as nearly at right angles as is possible. The block corners at intersections shall be rounded at the property line with a curve having a radius of not less than 15 feet.
H. 
Street jogs with center-line offsets of less than 125 feet shall be prohibited.
I. 
A tangent at least 100 feet long shall be introduced between reverse curves on arterial and collector streets.
J. 
When connecting street lines deflect from each other at any one point by more than 10° and not more than 45°, they shall be connected by a curve with a radius of not less than 100 feet for minor streets and 300 feet for arterial and collector streets.
K. 
All changes in grade shall be connected by vertical curves (parabolic) designed to provide a smooth transition and adequate sight distance.
L. 
Dead-end streets (culs-de-sac).
(1) 
Dead-end streets (culs-de-sac) shall not be longer than 600 feet and shall provide a turnaround at the end with a radius of not less than 60 feet and tangent wherever possible to the right side of the street.
(2) 
If a dead-end street is of a temporary nature, a similar turnaround shall be provided and provisions made for future extension of the street and reversion of the excess right-of-way to the adjoining properties.
M. 
No street shall have a name which will duplicate or so nearly duplicate as to be confused with the names of existing streets. The continuation of an existing street shall have the same name.
N. 
Where a tract is subdivided into larger parcels than ordinary building lots, such parcels shall be arranged so as to allow the opening of future streets and logical further subdivisions.
O. 
Private streets shall not be approved nor shall public improvements be approved for any private street.
P. 
Any streets or roads created in a subdivision or shown on any map must comply with the provisions providing standards for road acceptance in the Borough of Hamburg before final approval of the subdivision can be given.
A. 
Block length and width or acreage within bounding roads shall be such so as to provide for convenient access, circulation, control and safety of street traffic within the subdivision. Block lengths shall not, under any circumstances, exceed 1,200 feet.
B. 
In blocks over 1,000 feet long, pedestrian crosswalks may be required in locations deemed necessary by the Planning Board. Such walkway shall be 10 feet wide and be straight from street to street.
C. 
For commercial, group housing, or industrial use, block size shall be sufficient to meet all area and yard requirements for such use.
A. 
Under no circumstances shall the Planning Board approve a subdivision for a housing development of two or more single-family dwellings unless each building lot or plot shall be not less than 100 feet in width measured at right angles to side lines and not less than 15,000 square feet. In areas fronting on curves and culs-de-sac the one-hundred-foot minimum width shall be measured at the building setback line at least 30 feet back of the street line and no dwelling shall be built less than 10 feet from any other side or rear property line.
B. 
Under no circumstances shall the Planning Board approve a subdivision for two or more single-family residential dwellings except and unless each lot or plot so subdivided shall provide a front yard of a mean depth of not less than 40 feet, a rear yard of a mean depth of not less than 20 feet, and a side yard between any building and side lot line of a mean width of 10 feet except that where the lot or plot is a corner lot, no building shall be closer to the front lot line than 40 feet, nor closer to the side street line than 25% of the lot width, but need not exceed 40 feet.
C. 
Under no circumstances shall the Planning Board approve a subdivision for one or more multiple-family dwellings unless each lot shall be not less than 100 feet in width measured at right angles to side lines and a depth of not less than 200 feet and not less than 20,000 square feet in area. In addition, the total area of each subdivided lot or plot used for multiple-family dwellings shall be increased (in addition to the total area hereinbefore set forth for each lot and plot used for multiple-family residential dwellings) 200 square feet for each apartment contained in the multiple-family dwelling which area shall be set aside for off street parking. Not more than one multiple-family dwelling shall be permitted on one subdivided lot or plot.
D. 
Under no circumstances shall the Planning Board approve a subdivision for one or more multiple-family dwellings unless each lot or plot so subdivided shall provide a front yard of a mean depth of not less than 40 feet, a rear yard of a mean depth of not less than 50 feet, and a side yard between any building and any side lot line of a mean width for each side yard of 20 feet, except that where the lot or plot is a corner lot or plot no building shall be closer to the front lot line than 40 feet nor closer to the side street line than 25% of the lot width, but need not exceed 40 feet.
Where it is a question as to the suitability of a lot or lots for their intended use as dwellings, commercial, industrial or other purposes due to factors such as rock formations, flood and drainage conditions, or similar circumstances, the Planning Board may, after adequate investigation, withhold approval of such lots.
