Existing features which would add value to residential
development, such as large trees, watercourses, historic spots and
similar irreplaceable assets, should be preserved, insofar as possible,
through harmonious design of the subdivision.
A.
Relation to topography. Streets shall be logically
related and conform insofar as possible to the original topography.
They shall be arranged so as to obtain as many as possible of the
building sites at or above the grades of the streets. A combination
of steep grades and sharp curves shall be avoided.
B.
Block size. Block dimensions shall be at least twice
the minimum lot depth and generally not more than 12 times the minimum
lot width required by this chapter. In long blocks, the Planning Board
may require the reservation through the block of a twenty-foot-wide
easement to accommodate utilities or pedestrian traffic.
C.
Intersections. Intersections of major streets by other
streets shall be at least 400 feet apart, if possible. A distance
of at least 150 feet shall be maintained between offset intersections.
Within 40 feet of an intersection, streets shall be approximately
at right angles and grades shall be limited to 1 1/2%. All street
intersection corners shall be rounded by curves of at least 25 feet
in radius at the property line.
D.
Safe sight distances shall be maintained as defined
by New York State Department of Transportation Policy and Standards
for Entrances to State Highways at minimum. The Town Superintendent
of Highways or Planning Board may require sight easements from property
owners and developers in order to meet the Town's standards.
[Amended 10-23-2002 by L.L. No. 11-2002]
E.
Design standards. [NOTE: Standards are not shown for
arterial streets, as they would in all probability be built by the
state or county.] Streets shall meet the following standards unless
otherwise indicated on the Town Plan:

F.
Continuation of streets into adjacent property. Streets
shall be arranged to provide for the continuation of principal streets
between adjacent properties where such continuation is necessary for
convenient movement of traffic, effective fire protection, efficient
provision of utilities and particularly where such continuation is
in accordance with the Town Plan. If the adjacent property is undeveloped
and the street must be a dead-end street temporarily, the right-of-way
and improvements shall be extended to the property line. A temporary
circular turnaround with a minimum radius of 60 feet shall be provided
on all temporary dead-end streets, with the notation on the plat that
land outside the street right-of-way shall revert to abutters whenever
the street is continued.
[Amended 4-25-1990 by L.L. No. 5-1990]
G.
Permanent dead-end streets (cul-de-sac). Where a street
does not extend to the boundary of the subdivision and its continuation
is not needed for access to adjoining property, it shall be separated
from such boundary by a distance of not less than 100 feet. Reserve
strips of land shall be left between the end of a proposed street
and an adjacent piece of property; however, the Planning Board may
require the reservation of a twenty-foot-wide easement to accommodate
pedestrian traffic or utilities. A circular turnaround with a minimum
right-of-way radius of 60 feet shall be provided at the end of a permanent
dead-end street. For greater convenience to traffic and more effective
police and fire protection, permanent dead-end streets shall be limited
in length to a maximum of 1,250 feet and a minimum of 450 feet, unless
those minimum or maximum lengths are modified by the Planning Board.
[Amended 4-25-1990 by L.L. No. 5-1990; 10-8-2003 by L.L. No. 7-2003]
H.
Street names. All streets shall be named, and such
names shall be subject to the approval of the Town Planning Board.
Names shall be sufficiently different in sound and in spelling from
other streets names in the Town so as not to cause confusion. A street
which is a continuation of an existing street shall bear the same
name.
I.
Improvements.
(1)
Streets shall be graded and improved with pavement,
street signs, sidewalks, streetlighting standards, curbs, gutters,
trees, water mains, sanitary sewers, storm drains and fire hydrants,
except where the Planning Board may waive, subject to appropriate
conditions, such improvements as it considers are not requisite in
the interest of public health, safety and general welfare.
(2)
Underground utilities required by the Planning Board
shall be placed between the paved roadway and street line, if possible,
to simplify location and repair of the lines, and the subdivider shall
install underground service.
[Amended 4-25-1990 by L.L. No. 5-1990]
(3)
Grading and improvements shall conform to the Town
minimum road specifications and shall be approved as to design and
specifications by the Planning Board.
[Amended 4-25-1990 by L.L. No. 5-1990]
A.
Arrangement. The arrangement of lots shall be such
that there will be no foreseeable difficulties for reasons of topography
or other conditions, in locating a building on each lot and in providing
access to buildings on such lots from an approved street.
B.
Access across a watercourse. Where a watercourse separates
the buildable area of a lot from the access street, provision shall
be made for the installation of a culvert or other structure, of a
design approved by the Town Highway Superintendent and/or the Town
Engineer.
A.
Parks and playgrounds. The Planning Board shall require
adequate, convenient and suitable areas for parks and playgrounds
or other recreational purposes to be reserved on the plat, generally
a minimum of 5% of the area of each subdivision, exclusive of roads,
but in no case more than 10% of the gross area of any subdivision.
The area shall be shown and marked on the plat, "Reserved for Park
or Playground Purposes." If the Planning Board determines that a suitable
park or parks of adequate size cannot be properly located in such
plat or is otherwise not practical, the Board may require as a condition
to approval of such plat a payment to the Town of an amount to be
determined by the Town Board, which amount will be available by the
Town for neighborhood park, playground or recreational purposes, including
the acquisition of property.
B.
Realignment or widening of existing streets. Where
the subdivision borders an existing street and the Official Map or
Town Plan indicates plans for realignment or widening of the street
that would require reservation of some land of the subdivision, the
Planning Board may require that such areas be shown and marked on
the plat "Reserved for Street Alignment (or Widening) Purposes."
C.
Utility and drainage easements. Where topography or
other conditions are such as to make impractical the inclusion of
utilities or drainage facilities within street rights-of-way, perpetual
unobstructed easements at least 30 feet in width for such utilities
shall be provided across property outside the street lines and with
satisfactory access to the street.
D.
Easements for pedestrian access. The Planning Board
may require, in order to facilitate pedestrian access from streets
to schools, parks, playgrounds or other nearby streets, perpetual
unobstructed easements at least 20 feet in width and easements along
perennial streams at least 75 feet measured from the thread of the
watercourse on both sides.
E.
Responsibility for ownership of reservations. Ownership
shall be clearly indicated on all reservations.
