The subdivider shall observe the following requirements
and principles of land subdivision in the design of each subdivision
or portion thereof.
[Amended 5-10-1995 by Ord. No. 685-95]
The subdivision plat shall conform to design
standards that will encourage good development patterns within the
municipality. Where either or both an Official Map or Master Plan
has or have been adopted, the 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.
A.
The arrangements 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.
Minor streets shall be so designed as to discourage
through traffic.
C.
Subdivision 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.
D.
The right-of-way width shall be measured from lot
line to lot line and shall not be less than 50 feet or as may be shown
on the Master Plan or Official Map, whichever is greater.
E.
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 governing body
under conditions approved by the Planning Board.
F.
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 said road. If the
subdivision is along one side only, one-half (1/2) of the required
extra width shall be dedicated.
G.
Grades of arterial and collector streets shall not
exceed 4%. Grades on other streets shall not exceed 10%. No street
shall have a minimum grade of less than one-half of one percent (1/2
of 1%).
H.
Street intersections shall be as nearly at right angles
as is possible and in no case shall be less than 60°.
I.
Street jogs with center-line offsets of less than
125 feet shall be prohibited.
J.
A tangent at least 100 feet long shall be introduced
between reverse curves on arterial and collector streets.
K.
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.
L.
All changes in grade shall be connected by vertical
curves of sufficient radius to provide a smooth transition and proper
sight distance.
M.
Dead-end streets (cul-de-sac) shall not be longer
than 600 feet and shall provide a turnaround at the end with a radius
of not less than 50 feet and tangent whenever possible to the right
side of the street. If 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.
N.
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.
A.
Block length and width of acreage within bounding roads shall be such as to accommodate the size of lot required in the area by Chapter 200, Zoning, and to provide for convenient access, circulation control and safety of street traffic.
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 at least 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.
B.
Insofar as is practical, side lot lines shall be at
right angles to straight streets and radial to curved streets.
C.
Each lot must front upon an approved street at least 50 feet in width, except lots fronting on streets described in § 178-12F of this article.
D.
Where extra width has been dedicated for widening
of existing streets, lots shall begin at such extra width line, and
all setbacks shall be measured from such line.
E.
Where there is a question as to the suitability of
a lot or lots for their intended use due to factors such as rock formation,
flood conditions or similar circumstances, the Planning Board may,
after adequate investigation, withhold approval of such lots.
F.
Intersecting property lines on corner lots adjacent
to the street lines shall be rounded to permit suitably rounded curb
corners. In no case shall such radius be less than 15 feet. Where,
in the opinion of the Board, traffic conditions or other controlling
factors demand a greater curvature, the Board may so require.
A.
In large-scale development, easements along rear property
lines or elsewhere for utility installation may be required. Such
easements shall be at least 15 feet wide and located in consultation
with the companies or municipal departments concerned.
B.
Where a subdivision is traversed by a watercourse,
drainageway, channel or street, there shall be provided a stormwater
easement or drainage right-of-way conforming substantially with the
lines of such watercourse and such further width or construction,
or both, as will be adequate for the purpose.
C.
Natural features, such as trees, brooks, hilltops
and views, shall be preserved whenever possible in designing any subdivision
containing such feature.
