It is the purpose of these specifications to
establish minimum acceptable standards of street construction in the
Town of Greenville, to conform to legal requirements in the State
of New York, which requirements and standards must be met and paid
for by the person or firm proposing that the Town take over such road
as a Town road. These specifications include, but are not limited
to, width, design, drainage, construction of base and pavement, curbs
and monumentation. Dedication of the right-of-way will not be accepted
until the developer's professional engineer or licensed land surveyor,
the Town Superintendent of Highways and the Town Engineer shall have
certified, in writing, that the construction of the street or road
has been completed in accordance with the approved plans and specifications
that follow and that the total right-of-way area has been cleared
of all debris and all construction completed in a workmanlike manner.
When new roads are offered to the Town for dedication, one ink on
cloth tracing of the as-built plan and profile showing all improvements,
including those within easements, and three copies of the dedication
map and deed description of the right-of-way, citing the filed map,
shall be submitted and certified to the Town of Greenville for approval,
prior to acceptance of said roads.
In his written certification, as required above,
the developer's professional engineer or licensed land surveyor shall
state clearly that he or his authorized representative has inspected
all phases of construction and that all work has been completed in
accordance with the approved plans and specifications. The developer
shall bear all costs in connection with said certification, including
resident inspection.
A.
A plan and profile of the proposed street shall be
prepared by a qualified professional engineer or qualified land surveyor,
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
roadway, storm drainage, including culverts and other drainage structures,
and the location of all easements and utilities. These plans and profiles
may be used as the basis for the dedication map and the as-built plans
and profiles required for approval, prior to acceptance of said road.
The plans shall also indicate the owner of the property and the name
of the developer, if other than owner. One copy each of the plans
shall be submitted to the Town Superintendent of Highways and the
Town Engineer at the time of application to make such road a Town
road and to the 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 Planning Board for
review and approval under the applicable subdivision regulations of
the Town. Such roadway must not be subject to any right or easement
in others which will in any interfere with its use as a road at all
times. Such roadway must be granted to the Town by a full covenant
and warranty deed, free of all liens and encumbrances, containing
the correct metes and bounds description, citing the filed 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, and
the filing fees must be paid by the applicant.
B.
Permanent and temporary easements must be furnished
in said deed granting to the Town the right to maintain all sanitary
sewers and utilities therein and all outlets 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 25 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 which would endanger those using such roadway.
The cost of removal of such obstructions shall be borne by the person
or firm proposing such road.
Plans submitted shall not be altered or amended
after having been approved by the Town Superintendent of Highways
and the Town Engineer 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
Superintendent of Highways or the Town Engineer, if during the course
of construction, in the opinion of the Town Superintendent of Highways,
the Town Engineer and/or the County Superintendent of Highways, such
additional structures or facilities are necessary to prevent any need
for future installations of utilities or culverts within rights-of-way
and easements, to assure the durability of pavement, future maintenance
of right-of-way or welfare and safety of the public, except that the
Town Planning Board may vary the requirements of such an order where
there are practical difficulties in the way of carrying out the letter
of such order, 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 the date of final approval by the Town Planning
Board, plans shall be resubmitted for approval as above.
A.
Performance bonds. Prior to the start of construction
of any street, the developer shall deposit with the Town Clerk a performance
bond of acceptable surety or shall deposit with the chief fiscal officer
of the Town acceptable negotiable government bonds, cash or certified
check, drawn upon a national or state bank, payable to the Town of
Greenville, guaranteeing:
(1)
That within three years the developer will complete
all the construction within all rights-of-way and easements, including
roadway, shoulders, curbs, if any, gutters, storm drainage, etc.,
and all utilities, including hydrants and house connections for each
lot in accordance with the approved plans and these specifications,
and that all claims for labor and materials in connection with said
construction have been paid in full prior to offering said road for
dedication to the Town.
[Amended 4-8-1998 by L.L.
No. 1-1998]
(2)
That, upon certification by the developer's professional
engineer or licensed land surveyor and by the Town Superintendent
of Highways and Town Engineer that the construction of the road has
been completed in accordance with the approved plans and specifications,
the developer will offer to dedicate the completed road to the Town
for use as a public highway, free and clear of all encumbrances. This
guarantee of dedication shall apply to the owner of the property as
well as the developer, where the two are not synonymous.
B.
Maintenance bonds.
(1)
Prior to acceptance by the Town of the dedication of the road as guaranteed in Subsection A(2), the developer shall deposit with the Town Clerk a maintenance bond of acceptable surety or shall deposit with the Chief Fiscal Officer of the Town acceptable government bonds, cash or certified check, drawn upon a national or state bank, payable to the Town of Greenville, guaranteeing that for a period of one year from the date of acceptance of the dedication of the road by the Town, the developer will maintain the street to the standard of construction set by these specification, normal wear and tear excepted. This shall be interpreted to mean that the developer will, at his own expense, repair and make good any defects or damage which may develop during this maintenance period as a result of faulty construction within the right-of-way or as a result of other construction by the developer outside the right-of-way. During the maintenance period the Town shall be responsible for snow and ice control, street cleaning, cleaning of culverts and catch basins and other work of similar routine nature, provided that such work has in no way been caused by the developer's operations.
(2)
The amount of the maintenance bond shall be equal
to at least 10% of the original amount of the performance bond.
(3)
Subsequent to the dedication of the road and after
receipt of the maintenance bond, the Town Board shall release the
performance bond.
A.
The Planning Board shall determine and designate into
which of the four following classifications each proposed street falls,
on the basis of one or more of the criteria hereinafter set forth:
[Amended 11-21-1977]
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 specification common to all classifications.
[Amended 11-21-1977]
C.
Criteria for classification.
(1)
Arterial or major streets. The proposed street shall
service needs similar or equal to state and/or County requirements.
(2)
Collector streets.
(a)
The proposed street is the direct and logical
continuation of a street that carried 500 or more cars during a twelve-hour
period, as shown on the latest traffic count.
(b)
The proposed street creates a shorter and more
convenient through traffic artery so that it can be reasonably expected
that traffic will be diverted from other major streets to such an
extent that it will reach at least 500 cars in 12 hours, two years
after opening.
(c)
The proposed street is the principal collector
for 300 or more homes in the neighborhood.
(d)
The proposed street could logically be expected
to become a major street because of future construction or other foreseeable
circumstances.
(e)
The proposed street may be used for commercial
or industrial purposes.
(3)
Minor streets. The proposed street will serve residential
subdivisions and may be a dead-end street with a one-hundred-forty-foot
diameter cul-de-sac, a loop (through street) or a street connecting
two existing Town, County or state highways.
(4)
Rural roads. The proposed road will serve private
rights-of-way and permanent culs-de-sac to serve as no more than 10
dwellings and shall be permissible at the discretion of the Planning
Board for the Town.
[Amended 11-21-1977]
A.
Figures 1 and 2 show the cross sections of the two
classifications for collector and minor streets. Figure 1C shows the
cross section of the classification for rural roads.[1] These give the required design, dimensions and construction
details which are applicable to each classification. The general and
more detailed specifications follow for design and construction, which
are applicable to both classifications of streets.
[Amended 11-21-1977]
[1]
Editor's Note: Said Figures are on file in
the Town offices.
B.
The developer shall design and construct streets which
shall conform to both the general and specific specifications.
A.
The developer shall establish and clearly mark, on
site, the limits of the right-of-way and easements, the center line
and grades of the finished road pavement and the location and elevations
of drainage structures as shown on the approved plans with construction
stakes. Such construction stakes shall be maintained at the developer's
expense until the construction of road pavement, drainage structures,
curbs, sidewalks and shoulders has been completed, inspected and approved
by the Town Superintendent of Highways and the Town Engineer.
Where surface water from streets must lead through
other than gutters and storm drains or existing stream channels, outside
the right-of-way, permanent drainage easements, having a minimum width
of 25 feet, shall be provided to a point where a natural watercourse
exists. In some cases, this may include easements over property outside
the boundaries of the subdivision involved. Natural stream or ditch
channels shall have a minimum of twenty-five-foot wide permanent easements
and shall be shown on the proposed plans of the subdivision. All permanent
easement lines shall be monumented.
A.
The developer shall complete the shaping of the right-of-way,
streams, ditches and easement areas to the line and grade as shown
on the approved plans and as otherwise may be directed by the Town
Superintendent of Highways and/or the Town Engineer. In the construction
of the roadway, all topsoil, loam, rocks larger than six inches and
organic material shall be removed, until a satisfactory subbase is
established. In fills of less than three feet, all topsoil shall be
excavated and removed. All fills shall be made with acceptable material
as approved by the Town Superintendent of Highways and/or the Town
Engineer. Such fills shall be made in layers of not more than eight
inches in depth and properly compacted with a ten-ton roller or equivalent.
B.
The subgrade shall be shaped to line and grade with
no depressions and shall be stable in all respects to the satisfaction
of the Town Superintendent of Highways and the Town Engineer before
the foundation course is laid. No large stones or rock ledges shall
protrude into the foundation course. Also, before the foundation course
is laid, all storm and sanitary sewers and all utilities, including
house connections for existing and future homes, and hydrants shall
have been installed, backfilled and compacted to the satisfaction
of the Town Superintendent of Highways and the Town Engineer. All
slopes and sidewalk areas shall be graded before the foundation course
is laid and all loose and exposed stones shall be removed.
The foundation course shall consist of run-of-bank
gravel, with a minimum depth of 15 inches or 10 inches of shale with
a top of five inches of run-of-bank gravel, as approved by the Town
Superintendent of Highways. It shall contain stones no larger than
four inches in thickness and be well graded from coarse to fine and
shall conform in all respects to materials section of these specifications.
The material shall be placed on the prepared subgrade in two layers,
and each layer shall be thoroughly compacted by rolling with a ten-ton
roller or other equivalent compaction equipment. After compaction,
the foundation course shall be fine-graded to an elevation allowing
for the three inches of wearing course and approved by the Town Superintendent
of Highways. In all cases, the degree of compaction shall be sufficient
to ensure that the subgrade will not weave under the roller. Stakes
with final line and grade shall be maintained by the developer at
all times to check the foundation course as well as pavement.
A.
The drainage system and/or culverts shall be designed
in accordance with established engineering principles and approved
by the Town Superintendent of Highways. Plans for any drainage structure
other than pipe culverts, when existing or proposed, shall be submitted,
in detail, to the Town Superintendent of Highways and the Town Engineer
for approval. The minimum slope of any drainage pipe or culvert shall
not generally be less than 1%. The approved plans shall show invert
elevations of the inlet and outlet of all drainage structures. Any
deviation from the approved plans shall be on approval of the Town
Superintendent of Highways or the Town Engineer, in writing. No culvert
pipe shall be less than 15 inches in diameter, unless by approval,
in writing. Pipe for culverts may be reinforced concrete or corrugated
metal pipe, which shall be fully bituminous coated and of a gauge
in accordance with the New York State Specifications for Corrugated
Metal Pipe, which shall conform to these specifications.
B.
The width of the trench in which the pipe is laid
shall be sufficient to permit thorough tamping of the backfill around
the pipe. A cushion of at least six inches shall be laid in line with
grade prior to laying the pipe. No rock over three inches thick shall
protrude or lay in this cushion. The soil below the cushion shall
be stable enough that there will be no settlement of pipe after backfilling
the trench.
C.
Fill or backfill adjacent to structures shall be deposited
on both sides to approximately the same elevation at the same time
and, when in back of abutments and walls, shall not be placed until
the material in front of these structures has been entirely placed
and compacted. Special care shall be exercised in placing and compacting
material immediately adjacent to pipe to avoid damage either to the
pipe or its alignment.
D.
All pipe shall be laid true to line and grade and
shall have a full, firm and even bearing. Pipe laying shall begin
at the downgrade end and progress in the upgrade direction. Pipe with
bell and spigot type joints shall be laid with the bells upgrade.
All connections for corrugated metal pipe shall consist of twelve-inch
corrugated metal bands lapping on equal portions of the sections to
be connected. Backfilling of the trench shall be done with run-of-bank
gravel or other suitable material approved by the Town Superintendent
of Highways and the Town Engineer. The backfill shall be made in layers
of no more than six inches, which shall be tamped and watered, as
necessary, to obtain satisfactory compacting. In no case shall the
top of any drainage pipe be less than 18 inches below the finished
grade of pavement.
E.
All drainage structures shall be of a size sufficient
to carry natural water runoff and stormwater and also that which,
in the opinion of the Town Superintendent of Highways and the Town
Engineer, may be reasonably anticipated from future construction both
from within the development and from adjoining properties which normally
drain across the area of the proposed development. Additional or larger
culverts and drainage structures shall be installed and paid for by
the developer if the Town Superintendent of Highways and the Town
Engineer so direct.
Catch basins and curb inlets shall be constructed
in order that surface water be intercepted. Generally, such structures
shall be spaced at 300 feet or less. On grades in excess of 6%, the
distance apart shall not exceed 250 feet. See Figure 3 for details
of construction.[1] Whenever, in the opinion of the Town Superintendent of
Highways and the Town Engineer, ground conditions or other circumstances
require it, larger or heavier materials, additional materials, reinforcing
or other modifications and improvements in design and construction
shall be made as directed by the Town Superintendent of Highways and
the Town Engineer, at any time prior to construction of pavement.
[1]
Editor's Note: Said Figure 3 is on file in
the Town offices.
Headwalls of concrete, plain or reinforced,
or stone masonry shall be constructed at the outlet and inlet ends
of culvert pipe. Culverts shall extend to the toe of embankment. See
Figure 4 for details of construction.[1] The bearing of all headwalls shall have a solid base.
If soft material is encountered, it shall be removed and backfilled
with run-of-bank gravel. It shall be the responsibility of the developer
that no headwalls shall crack or become tipped from settlement. A
concrete mix of 3,500 pounds per square inch after 28 days shall be
used.

Editor's Note: Said Figure 4 is on file in
the Town offices.
If, in the opinion of the Town Superintendent
of Highways and the Town Engineer, it is necessary to intercept and
carry away groundwater within the limits of the right-of-way, to protect
the stability of the roadbed, curb or sidewalk areas, the subdrainage
required by the Town Superintendent of Highways shall be installed.
Perforated pipe or porous wall pipe having a minimum diameter of four
inches, encased in six inches of three-fourths-inch clean crushed
stone or crushed gravel, shall be used for such purpose in amount
deemed necessary by the Town Superintendent of Highways and the Town
Engineer.
Roof and cellar drains shall in no case be allowed
to flow onto the street right-of-way, nor be connected to any sanitary
sewer. With the approval, in writing, of the Town Superintendent of
Highways or the Town Engineer, these drains may be piped to existing
stormwater pipe drains, if any, to which they will be connected on
top only. Such drains must be installed prior to the start of the
application of the foundation course. Drains from sanitary sewers
or septic tanks will not be permitted to flow into road ditches or
storm drains under any circumstances.
Generally, the grade of any street shall not
be in excess of 10% nor less than 1%. Only by permission of the Town
Superintendent of Highways and the Town Engineer shall the grade of
more than 10% be permitted, due to topographic conditions. Differences
in grade will be effected with a vertical curve of sufficient length
to allow a vertical sight distance of no less than 250 feet, based
on a four-foot elevation.
On all streets, six-inch portland cement concrete
curbs shall be constructed on both sides of the street as shown in
Figure 1, prior to laying street pavement to the dimensions and specifications
shown in Figure 5.[1] A base course of six inches of run-of-bank gravel, tamped
and free of stones over two inches in thickness, shall be laid under
all curbing. A concrete mix of 3,500 pounds per square inch after
28 days shall be used and shall be finished and cured to the satisfaction
of the Town Superintendent of Highways and the Town Engineer. The
developer, at his own expense, shall replace any curbing that has
settled, cracked, scaled or has become damaged in any way by the developer
before and within the one-year maintenance period after dedication.
Curbs shall be depressed four inches at all driveways. Stone curbs
(Figure 6) may be substituted on approval of the Town Superintendent
of Highways and the Town Engineer.[2]
A.
The developer shall design and construct all driveways
within the limits of the right-of-way with sufficient sight distance
and with a grade of no more than one inch per foot from the curb to
the right-of-way line. The minimum width of the driveway pavement
at the curb or street pavement line shall be 15 feet, tapering to
a minimum of 10 feet at the right-of-way line. All driveways shall
have a six-inch run-of-bank gravel foundation course from curb to
right-of-way line and no less than two-inch bituminous penetration
macadam wearing course from curb or street pavement line to right-of-way
line, which shall be applied during or after the laying of the street
pavement.
B.
All driveways shall be graded to the satisfaction
of the Town Superintendent of Highways and the Town Engineer prior
to the surfacing of such driveways.
A.
Where sewer lines, storm drains or utilities traverse
or cross roads which are under the jurisdiction of the state or County,
the developer shall post bonds and shall obtain all necessary permits
and assume the costs in connection with the bonds and departmental
supervision.
B.
All requirements of the permits shall be fully complied
with. If special requirements for sheeting, backfilling, compaction,
paving or other items of work are called for in the permit, the developer
shall perform all such work as directed, and acceptance of such work
shall not be made until it is approved by the agency having jurisdiction
over the roadway.
A.
All intersections with existing Town or County roads
shall be constructed with the edge of pavement radius of thirty-five-foot
minimum. Intersections within the development shall be constructed
with edge of pavement radius of thirty-five-foot minimum. All intersecting
streets shall have a minimum horizontal sight distance of 250 feet
in each direction. Exceptions for less than 250 feet shall be in writing
and approved by the Town Superintendent of Highways and the Town Engineer.
B.
Where a development street intersects a Town or County
road, the approved plans shall show the proposed type, length and
diameter of pipe and drainage flow along said road. The pipe shall
be installed and paid for by the developer under the direction of
the Town Superintendent of Highways and the Town Engineer, or the
County Superintendent of Highways or his representative, as the case
may be.
C.
The grade of the intersecting street with a Town or
County road shall take into consideration the existing grade of the
Town or County road at the right-of-way or road line of said road
and shall be satisfactorily transitioned to ensure a smooth, vertical
intersection. The County Superintendent of Highways shall be notified
of all intersections with County roads, for approval of location,
grade and drainage structures.
After the foundation course has been inspected
and approved by the Town Superintendent of Highways with respect to
proper compaction and cross section and found to be at a grade allowing
three inches of finished pavement, one of the following pavements
shall be laid:
A.
Road mix macadam.
(1)
A prime coat the width of the pavement shall be applied
to the foundation course prior to laying stone for road mix pavement.
The prime coat rate of application will be 0.4 gallons per square

be made by the Town Superintendent of Highways and the Town Engineer
as to line, grade and thickness.
C.
Asphaltic concrete base course.
(1)
Under this alternative, the developer shall substitute
an asphaltic concrete base course equal in compacted thickness to
that specified for penetration macadam base course.
(2)
After the subbase has been completed to the satisfaction
of the Town Superintendent of Highways, asphaltic concrete conforming
to the current specifications of the New York State Department of
Transportation (NYSDOT), latest revision, for Item 45SX, bottom course
asphaltic concrete Type 1A, shall be uniformly spread by self-propelled
mechanical spreader equipped with tamping bars and heating unit and
in sufficient depth as to provide a finished compacted thickness after
rolling, equal to that specified for penetration macadam base course.
The base material in place shall be thoroughly rolled with a ten-ton
steel-tired roller. Approval of this base course shall be made by
the Town Superintendent of Highways and the Town Engineer as to line,
grade and thickness.
D.
Asphaltic concrete surface courses.
(1)
After the stone or asphaltic concrete base course
has been completed to the satisfaction of the Town Superintendent
of Highways and the Town Engineer, a two-course bituminous concrete
wearing course shall be constructed, conforming to the NYSDOT specifications,
latest revision, for Item 51M, asphalt concrete.
(2)
After the base course has been thoroughly cured and
cleaned of all foreign material, a bituminous concrete binder course
shall be uniformly spread by a self-propelled mechanical spreader
with tamping bars and heating unit in sufficient depth as to provide
a finished compacted thickness after rolling of not less than 1 1/2
inches. The course in place shall be thoroughly rolled with a ten-ton
roller. After the binder course has been completed and thoroughly
cleaned of foreign material, a tack coat of asphalt emulsion shall
be applied to the surface at the rate of 1/10 gallon to 1/20 gallon
per square yard; in the event that the binder course has been subject
to traffic for an extended period of time, a final wearing course
of fine bituminous concrete shall be uniformly spread by a self-propelled
mechanical spreader equipped with tamping bars and heating unit and
in sufficient depth as to provide a finished compacted thickness after
rolling of not less than one inch. The fine wearing course in place
shall be thoroughly compacted with a two- or three-wheel tandem roller
weighing approximately ten tons. Extreme care shall be exercised in
the placing of bituminous concrete to ensure that all longitudinal
joints shall be lapped in the placing of adjoining strips and all
lateral joints are trimmed before continuing with the placing of additional
materials on that strip. Approval of the wearing course shall be given
by the Town Superintendent of Highways and the Town Engineer.
Final decision as to the interpretation of any
part of these street specifications shall rest with the Town Superintendent
of Highways and/or the Town Engineer. They shall have the authority
to modify the requirements of these specifications when, in their
opinion, conditions make it impracticable to follow the strict letter
of these specifications or when conditions make it unnecessary to
do so.
Conflicting specifications and materials not
covered herein shall be governed by "Public Works Specifications,"
State of New York, Department of Public Works, Division of Construction,
latest revision.
A.
Run-of-bank gravel. All material shall be hard stone
