Street layouts and grades shall be related approximately
to the existing topography, and the streets shall be arranged to obtain
as many as possible of the building sites at or above the grades of
the streets. Steep grades shall be avoided as well as the combination
of steep grades and curves.
Planned streets may exist in the Official Map
within the parcel to be subdivided which have not as yet been constructed.
Such planned streets must be shown on any proposed subdivision plat,
and the strip acreage, 60 feet wide, must be reserved and excluded
from the minimum acreage of any lots. In cases where the planned street
has not been constructed across adjacent properties and it is advantageous
to the overall subdivision to make small adjustments in the location
of said street, the extent of the proposed relocation of said street
shall be included on an insert within the subdivision plat indicating
the extent to which the planned course of the street has been altered.
All streets shall be of sufficient width, suitable
grade and shall be suitably located and adequately constructed to
accommodate the prospective traffic, to facilitate drainage and to
afford access for fire-fighting, snow removal and road maintenance
equipment. Such streets shall be coordinated so as to compose a convenient
system and to cause no undue hardship to adjoining property.
Where a tract is subdivided into lots substantially
larger than the minimum size required by the Village ordinances, the
Board may require that streets and lots be laid out so as to permit
future subdivision in accordance with the requirements contained in
this chapter.
Monuments shall be set along one side of each
street at all street corners, angle points, points of curvature and
tangency and at such intermediate points as may be required by the
Engineer. Street intersections with main traffic arteries shall be
monumented at both sides of the intersection. Monuments shall be of
such material, size and length as may be approved by the Engineer.
Monuments shall be set three inches above ground surface.
In cases where construction of a proposed street
requires filling or excavating at or near a property line, the Planning
Board and the Village Engineer shall make certain that appropriate
grading, bulkheading or retaining walls shall be provided by the subdivider
to preserve the existing topography and ground cover of the adjacent
property if deemed necessary by the Board or the adjacent property
owner.
The Planning Board and the Village Engineer
shall pay particular attention to the requirements for proper drainage
of both the land and streets to be improved. Street construction shall
make allowance for the proper drainage of surface water from the street
itself and abutting properties. In no case shall the proposed street
be allowed to overtax the drainage capacity of the existing street
to which it leads. Drainage requirements are delineated in detail
in the street specifications.
In the case of newly constructed streets across
newly improved land, the Planning Board may require the planting of
appropriate shade trees to retain the characteristically rural appearance
of the area. Such trees shall be planted in a subdivision in accordance
with the following restrictions:
A. Trees shall be of nursery stock of an approved species
grown under the same climatic conditions as at the location of the
development. They shall be of symmetrical growth, free of insect pests
and disease, suitable for street use and durable under the maintenance
contemplated. The following are declared to be approved: Thornless
honey locust, London plane, Oriental plane, English elm, Norway maple,
Horse chestnut, Sweet gum, Pin oak, Little leaf linden, European linden,
Gingko.
B. The trunk diameter shall be a minimum of 2 1/2
inches, measured at a height of six inches above the finished ground
level.
C. Trees shall be planted at intervals of from 40 feet
to 60 feet apart (depending upon the species) along both sides of
the street and shall be located within the street, three and one-half
(3 1/2) feet from the right-of-way line. The Planning Board may
waive this specification in favor of planting an equivalent number
of trees in landscaped groups.
D. All planting shall be done in conformance with good
nursery and landscape practice. The trunk of each tree shall be wrapped
with burlap, and each tree shall be staked with two cedar poles secured
to the tree by means of wire through rubber hoses. All trees shall
be transplanted balled and burlapped, and the ball shall be at least
two and one-half (2 1/2) feet in diameter.
E. Trees planted under overhead utility wires should
take into account the potential interference with those wires from
future growth.
