Street and lot arrangement and other subdivision features shall
meet the following minimum requirements:
A. The plat shall conform to such plan or plans for the land being subdivided
and its general locality as may have been prepared and adopted by
the Planning Board.
B. All streets or roads which are so designed or situated as to become
a part of the major thoroughfare system of the municipality, as may
have been indicated by the Planning Board, shall be coterminous with
adjoining links in said system and shall be at the same or greater
widths, and minor streets shall be so arranged as to discourage fast
driving and use by through traffic.
C. All new traffic streets or roads shown on the Master Plan of the
municipality, if such exists, shall have right-of-way widths of not
less than 50 feet, and greater widths may be required when warranted
by anticipated traffic volumes. All other streets shall have right-of-way
widths of not less than 50 feet, except that in the case of culs-de-sac
and other streets of similar nature, the Board may approve rights-of-way
of lesser widths. When a subdivision fronts on an existing street
or road of insufficient width, the Planning Board may require the
subdivider to cede a sufficient strip along such frontage to enable
the necessary widening of his side of the existing street or road;
and whenever practicable, frontage upon major arterial streets and
highways designed for fast and heavy traffic shall be developed with
a minimum of direct access upon the main-traveled way by introduction
of marginal service roads or by reversing the frontage and providing
a planted buffer strip between the highway and the rear of lots or
by other such means. Land fronting on other main streets and highways
shall be developed generally with the long way of blocks running parallel
to the main thoroughfare.
D. Ordinarily, blocks, the distance between street intersections, shall not be less than 500 feet nor more than 1,200 feet in length and not less than 200 feet nor more than 350 feet in width and shall otherwise conform to lot requirements as contained in Chapter
280, Zoning.
E. Street grades shall not exceed 4% on main traffic streets and 10%
on all other streets. All streets shall have sufficient gradient for
proper surface drainage, and in no case shall the grade be less than
1/2 of 1%.
F. Lots shall have an area, width and depth sufficient to satisfy the minimum requirements of Chapter
280, Zoning, and the Planning Board may urge upon the subdivider greater lot sizes and dimensions when deemed to the mutual advantage of the subdivider and the community. All lots shall be adaptable to the intended purpose without danger to health or peril from flood, erosion or other menace.
G. For all rectangular lots and for all other lots when practicable,
sidelines shall be at right angles to the streets upon which the lots
face or radial to curved-street lines.
H. Alleys not less than 20 feet in width or other access facilities
shall be provided at the rear of all lots designed for business uses,
and off-street parking spaces may be required in convenient relation
to lots or areas intended to be developed or sold for such uses.
I. Other street design standards.
(1) Street intersections shall be as nearly at right angles as is possible.
(2) Street jogs with center-line offsets of less than 125 feet shall
not be permissible.
(3) A tangent of not less than 100 feet shall be introduced between reverse
curves on all main and secondary thoroughfares.
(4) All changes in grade shall be connected by vertical curves of sufficient
radius to provide smooth transition.
(5) Cul-de-sac streets of a permanent nature shall not exceed 600 feet
in length and shall be provided with a turnaround at the end having
a radius of not less than 35 feet.
J. Utility and drainage easements and retention of natural features.
(1) In large-scale developments, easements along rear or side lot lines
for the installation of utilities may be suggested or required. Such
easements, if provided, shall be not less than 15 feet wide, and their
locations shall be approved by the municipal or private utility agency
or agencies concerned.
(2) Where a subdivision is traversed by a watercourse or stream to be
kept permanently open, there shall be provided a stormwater or drainage
flow easement at least 10 feet in width sufficient for such purposes.
(3) Natural features, such as trees, streams and views, shall be preserved
to every practicable extent in all subdivision design and development.
K. In appropriate cases, the Planning Board may require reservation
of such needed public lands as those for parks, playgrounds and school
grounds for a period of one year following the date of final plat
approval, pending action by the appropriate public agency toward accepting
or acquiring such land or lands for public use. The Board may urge
upon the subdivider the free dedication of such land or lands to public
purposes as of economic advantage to the subdivider. A subdivider
or his agent shall not sell land or lots in relation to a plat showing
land or lands for public use unless it is clearly indicated on the
plat whether such land is permanently dedicated to the indicated public
purpose or is temporarily reserved for such purpose conditional upon
its acquisition by the appropriate public agency.
L. No plat showing reserve strips controlling the access to public ways
shall be approved unless the control and disposal of such reserve
strips are given to the municipality under conditions meeting the
approval of the Planning Board, and no half-streets at property boundaries
shall be acceptable.
M. Building setback lines of a depth approved by the Planning Board shall be established for each street and shown on the final plat. In no case shall the depth of such setbacks be less than the front yard or building setbacks required under Chapter
280, Zoning, or any other municipal ordinance.
Permanent monuments shall be installed in the manner and in
the locations prescribed by and in additional locations as may be
indicated by the Municipal Engineer or other qualified municipal authority.
