[HISTORY: Adopted by the Town Board of the
Town of Deerpark 3-24-1986. Amendments noted where applicable.]
A.
It is the purpose of these specifications to establish
minimum acceptable standards of street construction for subdivisions
which have established by the Town of Deerpark, Orange County, New
York, which requirements and standards must be met and paid for by
the person or firm proposing that the Town of Deerpark take over such
road as Town roads.
B.
These specifications include but are not limited to
width, design, drainage construction of base and pavement, curbs and
monuments. Dedication of the right-of-way will not be accepted until
the developer's professional engineer and the Town of Deerpark Superintendent
of Highways, or Engineer for the Town of Deerpark shall have certified
to the Town of Deerpark Town Board, in writing, that the construction
of the street or road has been completed in accordance with the approved
plans and specification that follow, and that the right-of-way area
has been cleared of all debris and all construction completed in a
workman like manner.
[Amended 7-21-1986]
A.
The Town of Deerpark Planning Board shall determine
and designate into which of the two following classifications each
proposed subdivision street falls on the basis of one or more of the
criteria hereinafter set forth. After submission of plans for review
to the Town of Deerpark Superintendent of Highways and the Engineer
for the Town of Deerpark.
[Amended 7-21-1986]
B.
Final plans shall be drawn to show, and the developer
shall construct each street in accordance with the particular specifications
for its designated classification as hereinafter set forth as well
as in accordance with the specifications common to all classifications.
A.
Suburban type streets.
(1)
The proposed street will serve residential subdivisions
with lot size less than one acre and with more than eight lots to
be developed in the subdivision at option of the Town of Deerpark
Planning Board.
(2)
The proposed street may be dead-end street with 140
feet diameter cul-de-sac, a loop (through street) or a street connecting
to existing Town, county, or state highway.
(3)
The proposed street may be used for commercial or
industrial purposes.
B.
Rural type streets.
(1)
The proposed street will serve residential subdivisions
with lot sizes of one acre or more, or with smaller lot sizes, if
not more than eight lots are to be developed in the subdivision, and
where rezoning to smaller lot size is not designated in the Zoning
Ordinance, or contemplated in the Comprehensive Plan, at the option
of the Town of Deerpark Planning Board.[1]
(2)
The above design criteria is the basis for design
with the Town of Deerpark Planning Board having final determination,
and it may override or suggest certain changes within the design criteria
of suburban and rural type streets.
Private roads within the Town of Deerpark are
not acceptable, however, under certain circumstances, may be allowed
only by the Town of Deerpark Planning Board approval.
In his written certification, as required, the
developer's professional engineer shall state clearly that he or his
authorized representative has inspected all phases of the street construction
and that all work has been completed in accordance with the approved
plans and specifications.
A.
A plan of the proposed street shall be prepared by
a qualified professional engineer licensed by the State of New York.
The plan shall clearly define the limits of the proposed right-of-way
by metes and bounds and shall include the location, widths, profiles
and grades of the proposed roadways, storm drainage, including culverts
and other drainage structures and the locations of all easements and
utilities. The plans shall also indicate owner of property and name
of developer if other than owner. One copy of each of the plans shall
be submitted to the Town of Deerpark Superintendent of Highways and
Town of Deerpark Town Engineer at the time of application to make
such road a Town road, and to the Orange County Superintendent of
Highways when said proposed street drains toward, intersects or may
otherwise affect a county highway. It will then be submitted to the
Town of Deerpark Planning Board for review and approval under the
applicable subdivision regulations of the Town of Deerpark. Such roadway
must not be subject to any right-of-way or easement of others which
will in any way interfere with its use as road at all times. Such
roadways must be granted to the Town of Deerpark by a full covenant
and warrantee deed containing the correct metes and bounds description
as shown on the approved map, which deed must be in such form as may
be required to entitle the same to be recorded in the Office of the
County Clerk of Orange County. A policy of title insurance or other
assurance of title satisfactory to the Town Attorney shall be provided
to the Town of Deerpark when the road offered is accepted. All expenses
incidental to the dedication and acceptance of any road shall be borne
by the applicant.
[Amended 7-21-1986]
B.
Permanent and temporary easements must be furnished
in said deed granting to the Town of Deerpark the right to maintain
all outlets of culverts and drainage structures for surface water
or natural stream drainage which will run from such roadway over private
property to a point where a natural watercourse exists and to which
such outlet and easement will carry such water. A minimum of 20 feet
width of easement shall be required for the maintenance of said easements.
C.
The proposed roadway must be constructed to conform
to the minimum requirements and standards set forth below. The minimum
width to be cleared shall include all trees, rock formations, buildings,
walls and any such things that would endanger those using such roadways.
The removal of such obstructions shall be borne by the person or firm
proposing such road.
A.
Plans submitted shall not be altered or amended after
having been approved by the Town of Deerpark Superintendent of Highways,
unless amended plans are resubmitted and approved. However, the developer,
at his own expense, shall provide additional storm drainage facilities
or utilities as may be ordered by the Town of Deerpark Superintendent
of Highways.
B.
If during the course of construction, in the opinion
of the Town of Deerpark Superintendent of Highways, the Town of Deerpark
Engineer, such additional structures or facilities are necessary to
prevent any need for future installation of utilities or culverts
within the pavement area, to assure the durability of pavement, further
maintenance of right-of-way, or welfare and safety of the public,
unless such variance conflicts with the provisions of a Town or county
official drainage map, in which event, the official map shall prevail.
If construction of said road has not been started within one year
from date of final approval by the Town of Deerpark, plans shall be
resubmitted and approved as above.
A.
