[HISTORY: Adopted by the Planning Board of
the Town of Union Vale 6-4-1974, approved by Town Board 6-10-1974
(Ch. A93 of the 1983 Code); amended in its entirety 2-4-2010 by L.L. No.
11-2010. Subsequent amendments noted where applicable.]
A.Â
It is
the purpose of these specifications to establish minimum acceptable
standards for the construction of public and private streets and related
improvements within subdivisions in the Town of Union Vale, including,
but not limited to, width, design, drainage, construction of base
and pavement, curbs and sidewalks, monuments and street name signs.
B.Â
In the
case of a proposed public street, construction of any street shall
not be considered complete and the dedication of the right-of-way
will not be accepted until the developer's professional engineer and
the Town Superintendent of Highways shall have certified to the Town
Board in writing that the construction of the street has been completed
in accordance with the approved plans and the specifications and all
other pertinent requirements which follow within this chapter.
C.Â
In the
case of a proposed private street, construction of any subdivision
street shall not be considered complete until the developer's engineer
and the Town Engineer shall have certified to the Planning Board in
writing that the construction of the street has been completed in
accordance with the approved plans and the specifications and all
other pertinent requirements which follow in this chapter.
A.Â
In his written certification, as required above, the
developer's professional engineer or qualified licensed land surveyor
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 these specifications.
B.Â
If any work or changes due to field conditions occur
that are not shown on the approved subdivision plan, such changes
or work done must be incorporated on the approved subdivision plan
and submitted to the Town Board at the time of dedication.
A plan of the proposed street shall be prepared
by a qualified engineer or qualified land surveyor properly licensed
by the State of New York. The plan shall clearly define the limits
of the proposed right-of-way and shall include the location, widths,
profiles and grades of proposed roadways, storm drainage, including
culverts and other drainage structures, soil erosion controls and
stormwater treatment, and the location of easements and utilities.
The plan shall be submitted to the Town Superintendent of Highways
and Town Engineer, and to the Dutchess County Commissioner of Public
Works when any street drains toward or may otherwise affect a county
highway, and to the Town Planning Board for review and approval under
the applicable subdivision regulations of the Town. Such plan so submitted
shall not be altered or amended after having been approved by the
Planning Board, unless an amended plan is resubmitted and approved
as above. However, the developer shall, at his own expense, provide
additional storm drainage facilities as may be ordered by the Town
Superintendent of Highways if, during the progress of the work, in
the opinion of the Town Superintendent of Highways, the Town Engineer
and/or the Dutchess County Commissioner of Public Works, such additional
structures or facilities are necessary to assure the durability of
pavement, the future maintenance of the right-of-way or the safety
of the public. If construction has not been started within one year
from the date of final approval by the Town Planning Board, the plan
shall be resubmitted and approved as above.
A.Â
Performance bond.
(1)Â
Prior to the start of construction of any improved
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 a certified
check drawn upon a national or state bank, payable at sight to the
Town Board, guaranteeing:
(a)Â
That within two years the developer will complete
all of the construction within the right-of-way, including roadbed,
shoulders, sidewalks, curbs, gutters, storm drainage, etc., and all
utilities, including hydrants and house connections for each lot,
in accordance with the approved plan and these specifications.
(b)Â
That, upon certification by the developer's
professional engineer or licensed land surveyor and by the Town Superintendent
of Highways that the construction of the street has been completed
in accordance with the approved plans and specifications, the developer
will dedicate the completed street to the Town for use as a public
highway, free and clear of all liens and encumbrances. This guaranty
of dedication shall apply to the owner of the property as well as
the developer, where the two are not synonymous.
(2)Â
As a guaranty for the performance of the above requirements,
the developer shall deposit, as heretofore set forth, a surety bond,
negotiable government bonds, cash or certified check, the minimum
total amount of which shall be determined by applying to the quantities
or dimensions shown on the approved plan the rates per unit as established
by the designated Town Engineer and Town Highway Superintendent.
B.Â
Maintenance bond. Prior to acceptance by the Town of the dedication of the street as guaranteed by Subsection A(1)(b) under performance bond above, 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, negotiable government bonds, cash or certified check drawn upon a national or state bank, payable at sight to the Town Board, guaranteeing that for a period of two years from the date of acceptance of the dedication of the street by the Town the developer will maintain the street to the standard of construction set by these specifications, 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 off 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 a similar routine nature, provided that such work has in no way been caused by the developer's operations. The amount of the maintenance bond shall be at least equal to 20% of the performance bond.
A.Â
Also prior to acceptance by the Town of the dedication
of the street, the developer shall file with the Town Clerk evidence
that he has taken out, for the same period of time as the maintenance
bond, an insurance policy in the amounts of $1,000,000/$2,000,000
for public liability and $200,000 for property damage, naming as the
insured the Town Board and/or the Town Highway Department and/or the
Town Superintendent of Highways.
B.Â
The purpose of this requirement for insurance is to
protect and defend the Town against any claims which may arise because
of the operations of the developer or of possible defects in work
performed by him.
C.Â
Subsequent to the acceptance of the dedication of
the street and after receipt of the maintenance bond and evidence
of insurance by the Town, the Town Board shall release the performance
bond.
A.Â
The Town Planning Board shall determine and designate
into which of the three following classifications each proposed subdivision
street falls on the basis of one or more of the criteria hereinafter
set forth:
B.Â
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 also hereinafter set forth,
as well as in accordance with the specifications common to all classifications.
A.Â
Collector streets.
(1)Â
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.
(2)Â
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.
(3)Â
The proposed street is the principal collector for
300 or more homes in the neighborhood.
(4)Â
The proposed street could logically be expected to
become a major street because of future construction or other foreseeable
circumstances.
B.Â
Commercial streets.
(1)Â
The proposed street is in an area zoned for commerce.
(2)Â
The proposed street is on or close to the dividing
line between a residential and commercial area so that it may reasonably
be expected to carry a substantial volume of commercial traffic.
(3)Â
The proposed street creates a shorter and more convenient
route between a commercial area and a major traffic artery.
(4)Â
The proposed street, for any other reason, may be
expected to carry a substantial volume of commercial or other nonresidential
traffic.
C.Â
Suburban or rural-type public subdivision streets.
(NB: This classification is intended to cover the majority of subdivision
streets.)
(1)Â
The proposed street shall not be or be reasonably
expected to become a through, commercial or industrial street.
(2)Â
The proposed street shall be a dead-end, loop or other
minor street within a development.
(3)Â
The proposed street is not or cannot reasonably be
expected to become a continuation or extension of a street of one
of the two above-described classifications. Should such be the case,
the proposed street shall take the classification of the street of
which it is a continuation or extension.
(4)Â
The proposed street does not or cannot reasonably
be expected to carry a substantial volume of traffic.
D.Â
Rural-type private subdivision streets. This classification
is intended to cover proposed residential subdivision streets, which
streets are proposed to remain under permanent private ownership and
maintenance responsibility. Such private subdivision streets shall,
except in the case of a conservation density subdivision of 500 or
more acres within the RD10 District that may be authorized by the
Town Board and Planning Board pursuant to § 280-a of the
Town Law, provide direct access from not more than eight single-family
residential lots, or eight dwelling units, to a public roadway.
A.Â
Figures 2 through 5 show cross-sections of each of
the four classifications of subdivision street. These give the required
design, dimensions and construction details which are applicable to
a particular classification.[1]
[1]
Editor's Note: Figures 2 through 5 are included
at the end of this chapter.
B.Â
Table 1[2] is a comparative summary sheet which lists the major items
of construction for all types of streets and may be useful as a check
list of requirements. Thereafter are set forth the general and more
detailed specifications for design and construction applicable to
all streets.
[2]
Editor's Note: Table 1 is included at the end of this chapter.
C.Â
The developer shall design and construct streets which
shall conform to both the specific and the general specifications.
A.Â
Except
in the case of the presence of an existing driveway access location
deemed in writing to be satisfactory by the agency of jurisdiction,
i.e., the Town Highway Superintendent, the Dutchess County Department
of Public Works or the New York State Department of Transportation,
no building permit may be issued for the construction of a principal
building or certificate of occupancy issued for commencement of the
use of open land for nonagricultural purposes until a driveway or
other highway access permit has been issued by the agency of jurisdiction
and a copy thereof submitted to the Code Enforcement Officer.
B.Â
Application
for Town driveway permit. In addition to the requirement set forth
above for a Town highway access permit, any person, firm or corporation
desiring to build, construct or locate a driveway entrance or exit
onto a Town highway of the Town of Union Vale or pave, repave or otherwise
modify that portion of an existing driveway within the Town's right-of-way
must first secure a permit for driveway construction from the Superintendent
of Highways. In considering the application for such permit, the Superintendent
of Highways may impose any restrictions or requirements that are deemed
necessary to protect all property and maintain public safety within
the Town right-of-way.
C.Â
General
requirements of construction.
(1)Â
The
applicant shall bear all construction and material costs within the
Town right-of-way and, before the permit for driveway construction
is issued, must deposit with the Superintendent of Highways an amount
set forth in the permit.
(2)Â
The
Town of Union Vale Superintendent of Highways shall be notified of
any construction within the Town right-of-way at least 48 hours before
commencing work. All work within the Town right-of-way must be acceptable
to the Town of Union Vale Highway Superintendent.
(3)Â
In
extreme conditions, if it is determined by the Town Engineer that
entrance on private property is necessary to correct a potential problem,
the applicant must sign a release allowing the Town Highway Department
to enter said premises for a correction of said problem before a permit
for driveway construction is issued. In any such event, the costs
of this work will be borne by the applicant.
The following conditions must be fulfilled to
develop lots along existing Town roads:
A.Â
The area between the center line of the existing roadway
and the new right-of-way must be cleared, grubbed and graded as described
elsewhere in these specifications.
B.Â
The existing Town roadway may require improvements
such as realignment, pavement widening and the installation of stormwater
management measures to satisfy requirements of applicable typical
road cross-sections.
The developer shall establish and clearly mark
on site the limits of the road right-of-way and easements, the center
line and grades of the road pavement and the location and elevation
of drainage and drainage structures in accordance with the approved
plans. Such markers shall be maintained at the developer's expense
until the construction of drainage, road pavement, curbs, sidewalks
and shoulders has been completed, inspected and approved by the Town
Superintendent of Highways and the Town Engineer.
B.Â
All ledgerock and rock outcroppings shall be removed
to below the elevation of the lowest point of the roadbed and shall
be done to afford proper site distance, drainage and runoff.
C.Â
All roots and stumps shall be grubbed, excavated and
removed from the above areas.
D.Â
Where possible, the roadbed within the right-of-way
may be realigned to afford the most practical construction of the
roadbed, in the opinion of the Town Engineer and Highway Superintendent.
A.Â
The developer shall complete the shaping of the road
right-of-way, streams and ditches and easement areas to the line and
grade as shown on the approved plan and as otherwise may be directed
by the Town Superintendent of Highways. All unsuitable or unstable
materials shall be completely excavated and removed from the right-of-way,
and all rocks or boulders larger than six inches in diameter shall
be excavated at least eight inches below the finished subgrade of
road pavement, drainage or drainage structures, curbs and sidewalks.
B.Â
Where fills are necessary to complete the required
line and grade or to backfill trenches or other excavation, the materials
incorporated in the work shall be acceptable to the Town Superintendent
of Highways and shall be placed in layers not exceeding eight inches
in depth, each layer to be thoroughly compacted by rolling with a
three-wheel, sheepsfoot, pneumatic tire or padded wheel roller or
by impact rammer or vibrator equipment in areas inaccessible to power
rollers. A compaction shall continue until the fills are firm and
unyielding.
C.Â
The rough grade of the road pavement, curb and sidewalk
areas shall be completed to within one inch above or below the finished
subgrade as shown on the approved cross section of the right-of-way
improvement.
D.Â
Earth shoulders and flow line of ditches and gutters
shall be maintained in satisfactory condition at the developer's expense
at all times during the course of construction of the subdivision
and until such time as the Town Board has accepted dedication of the
right-of-way.
E.Â
The areas between the curbline and the right-of-way
line must be graded and seeded in order to prevent erosion.
A.Â
The width of the trench in which the pipe is placed
shall be sufficient to permit thorough tamping of the backfill under
the haunches and around the pipe. Where rock, in either boulder or
ledge formation, is encountered, it shall be removed below grade and
replaced with suitable materials in such a manner as to provide an
earth cushion having a thickness under the pipe of not less than eight
inches, and where there are excessively heavy fills over the top of
the pipe, the Town Superintendent of Highways may specify that an
earth cushion up to 1/2 inch in thickness per foot of fill be placed
over the top of the pipe. In no case shall the top of any drainage
pipe be less than 18 inches below the finished grade of the pavement.
Where soft, spongy or other unstable soil is encountered at the grade
established, all such unstable soil under the pipe and for a width
of one diameter on each side of the pipe shall be removed and replaced
with run-of-bank gravel or other acceptable material. In all cases,
the bed shall be thoroughly compacted and shall provide a firm foundation
for the pipe. See Figures 6A and 6B.[1]
[1]
Editor's Note: Figures 6A and 6B are included at the end of
this chapter.
B.Â
Pipe shall be laid to true line and grade on the prepared
bed of the trench. All connections for making field joints in stormwater
pipe shall be silt-tight; field joints in corrugated metal pipe shall
consist of corrugated metal bands so constructed as to lap on equal
portions of each of the culvert sections to be connected. All joints
in making field connections of reinforced concrete pipe shall be filled
with Portland cement mortar.
C.Â
Backfilling of trenches shall be done in accordance with the subsection on fills under § A215-13, Excavation, filing and rough grading.
D.Â
Any additional drainage facilities not shown on the
approved plan and which may be ordered by the Town Superintendent
of Highways shall be constructed by the developer at the developer's
expense and in accordance with these specifications.
A.Â
Storm drain and culvert pipe may be of either coated
corrugated steel, corrugated aluminum, smooth interior corrugated
polyethylene or reinforced concrete, with a minimum diameter of 15
inches.
B.Â
Storm drain and culvert pipe shall conform to the
appropriate sections of the current Standard Specifications, New York
State Department of Transportation, Design and Construction Division,
with the following exceptions:
(1)Â
In cases where corrugated metal pipe is installed,
the invert of the pipe shall be paved with bituminous material to
a depth of nod less than 1/8 inch measured over the crest of the corrugations
on the inside circumference.
(2)Â
All collars or connecting bands used with corrugated
piping shall have a minimum width of 12 inches; connection bolts shall
have a minimum length of six inches.
(3)Â
All reinforced concrete pipe shall be manufactured
with slip or bell and spigot joints.
C.Â
The material of construction and location of use of
all storm drain and culvert pipe shall be approved by the Town Superintendent
of Highways and the Town Engineer prior to construction or installation.
D.Â
All storm drain main lines are to be laid out to the
extent practical so that they will not be under proposed roadways
or streets. If possible, storm drain main lines should be designed
to be installed on the high side of the right-of-way.
The following specifications and drawings show
the minimum acceptable construction for typical catch basins and curb
inlets.[1] Whenever, in the opinion of the Town Superintendent of
Highways, 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 at any time prior to paving.
[1]
Editor's Note: All drawings are included at
the end of this chapter.
Catch basins shall be constructed at all points
of change of slope or alignment and at all junction points. At no
time shall catch basins be spaced farther apart than 300 feet on slopes
less than 3%, 250 feet on slopes from 3% to 6% and 200 feet on slopes
over 6% in steepness.
Plans for the design and construction of all
catch basins, including matters related to excavation and concrete
bases, are subject to the approval of the Town Superintendent of Highways.
In any event, under this chapter the minimum acceptable design and
construction of any catch basin shall be as shown on Figure 7.[1]
[1]
Editor's Note: Figure 7 is included at the end of this chapter.
Plans for the design and construction of all catch basins, including
catch basin walls, are subject to the approval of the Town Superintendent
of Highways. In any event, under this chapter the minimum acceptable
design and construction of any catch basin shall be as shown on Figure
7.[1]
[1]
Editor's Note: Figure 7 is included at the end of this chapter.
A.Â
Concrete walls around all pipes entering or leaving
the catch basin shall be cut to fit the contours of the pipes as closely
as possible. Remaining interstices between the pipe and the catch
basin structure may not exceed two inches and shall be solidly filled
with mortar for the full thickness of the wall. No blocking or bricking
of openings shall be allowed. Ends of all pipes shall be cut flush
with the inside surfaces of the catch basin walls.
B.Â
When the diameter of the effluent pipe is greater
than that of an influent pipe, the elevation of the top of the influent
pipe shall be no lower than the elevation of the top of the effluent
pipe.
C.Â
When the diameter of the effluent pipe is the same
as or smaller than that of an influent pipe, the elevation of the
invert of the influent pipe shall be no lower than the elevation of
the invert of the effluent pipe. In no case shall the top of any influent
pipe be more than five feet above the invert of the effluent pipe.
A.Â
All catch basins shall be capped with curb inlets
having a minimum frame opening of 30 inches by 48 inches. Curb inlets
shall be similar or equal to Syracuse Castings Pattern No. 3408 bicycle-proof,
or equivalent, as designated by the Town Superintendent of Highways.
B.Â
Curb inlets shall be installed so that the top of
the grating is one inch below the adjacent asphalt surface. The grate
shall be installed with a slope that matches the road crown.
C.Â
Curb-front openings on all curb inlets shall have,
centered in the opening, a solid horizontal bar to prevent the ingress
of small children. This bar shall be part of the casting or solidly
welded in place subsequent to manufacture.
Catch basins having a depth of greater than
48 inches from the finished surface to the top of the concrete base
shall be provided with steps. Steps shall be of aluminum or plastic.
They shall be solidly set in the masonry at the time of construction
and shall extend all the way through the wall. The steps shall extend
4 1/2 inches inside the wall of the catch basin. The top step shall
not be more than 18 inches below the finished surface, and thence
to the base, steps shall be no more than 18 inches apart.
A.Â
Before fine grading or construction of curbs and sidewalks
is started, all storm and sanitary sewers and all utilities, including
house connections and hydrants, shall have been installed, and all
fill and backfill shall have been thoroughly compacted to the satisfaction
of the Town Superintendent of Highways.
B.Â
After completion of the rough grade and prior to the
laying of the foundation course, the subgrade shall be shaped to line
and grade and thoroughly compacted with an approved self-propelled
roller weighing not less than 10 tons. All hollows and depressions
which develop under rolling shall be filled with acceptable granular
material and again rolled, this process to be continued until no depressions
develop. The subgrade shall not be muddy or otherwise unsatisfactory
when the foundation course is laid upon it. Any soft or unstable portions
of the subgrade which develop under the roller shall be completely
excavated and removed from the right-of-way and shall be replaced
with acceptable granular material and the area regraded and compacted
as above.
C.Â
Fine grade shall conform to the prescribed width of
pavement and shall extend equidistant from the center line of the
road right-of-way and shall conform to the typical cross section of
the road pavement and to the approved line and grade.
A.Â
After the fine grade has been constructed to the satisfaction
of the Town Superintendent of Highways, the developer shall furnish
and place a foundation course of approved run-of-bank gravel, crusher
run stone or crusher run gravel to the depths as called for in these
specifications. All materials acceptable for this course shall be
hard, durable and sound and shall be well graded from coarse to fine,
the maximum diameter of the large particles not exceeding 2/3 of the
thickness of the compacted foundation course, and 90% to 100%, by
weight, of the particles shall be of such size as will pass through
a four-inch-square hole, not more than 70% by weight pass the No.
40 mesh sieve and not more than 10% by weight pass the No. 200 mesh
sieve.
B.Â
The materials shall be placed on the finished subgrade
by means of mechanical spreaders and shall be thoroughly compacted
by rolling with a self-propelled ten-ton roller. Water shall be added
to the materials in such amounts as the Town Superintendent of Highways
may consider necessary for proper compaction. After compaction, the
course shall be true to grade, and cross sections, and any depressions
shall be eliminated by the use of additional granular materials thoroughly
rolled in place. In all cases, the foundation course must be so thoroughly
compacted that it will not weave under the roller.
C.Â
In order
for the foundation course to be determined acceptable by the Town
Superintendent of Highways, the developer must:
(1)Â
Demonstrate
through required compaction tests in a number and at locations specified
by the Town Engineer 95% maximum density as determined by ASTM D698,
Standard Proctor Density.
(2)Â
Document
through presentation of a preliminary as-built drawing that installed
catch basin locations, pipe sizes and slopes, road location and profile
are in accordance with approved design plans.
A.Â
After the foundation course has been completed to the satisfaction of the Town Superintendent of Highways in the manner stated within above § A215-24, Subsection C, asphaltic concrete conforming to the current specifications of the New York State Department of Transportation for base course, NYSDOT Type 3 Binder, shall be uniformly spread by a self-propelled mechanical spreader equipped with tamping bars and a heating unit in sufficient depth as to provide a finished compacted thickness after rolling equal to that specified for a penetration macadam base course. The base material in place shall be thoroughly rolled with a ten-ton roller. The base course installation shall occur between April 15 and November 15 of any given calendar year.
B.Â
After compaction, the top surface of this course shall
not extend above the theoretical elevation for this course, and when
tested with a straightedge 16 feet in length, any depressions over
1/4 inch below the theoretical grade line shall be satisfactorily
eliminated.
A.Â
After the asphaltic concrete base course has been
completed to the satisfaction of the Town Superintendent of Highways,
including satisfactory repair of any conditions identified by the
Highway Superintendent in the binder, curbing, drainage, shoulders,
etc., a one- or two-course bituminous concrete wearing course shall
be constructed conforming to New York State Department of Transportation
specification for binder course and/or top course, NYSDOT Type 6F.
B.Â
After the base course has been thoroughly cured and
cleaned of all foreign material, a bituminous concrete binder course
and/or bituminous top 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 as
called for in these specifications and the approved plan. The course
or courses shall be thoroughly rolled with a ten-ton roller.
C.Â
Where a two-course wearing surface is required and
in the event that the binder course has been subject to traffic for
an extended period of time, prior to the installation of the top surface
course the binder course must be thoroughly cleaned of all foreign
material and a tack coat of asphalt emulsion must be applied to the
surface at the rate of 1/10 to 1/20 gallons per square yard.
D.Â
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 that all lateral joints
are trimmed before continuing with the placing of additional materials
on that strip.
E.Â
The final wearing course(s) shall not be constructed
until at least 95% of the buildings have been constructed and any
damage to the base course has been corrected to the satisfaction of
the Highway Superintendent.
A.Â
Asphaltic berms or concrete curbs may be required
to manage storm drainage. If required by the Town, such asphaltic
berms or concrete curbs shall be constructed on both sides of the
street as shown on Figures 2 through 5 and be of the material and
dimension described in Figures 1, 8A and 8B.[1]
[1]
Editor's Note: All figures are included at the end of this
chapter.
B.Â
Where required by the Town Superintendent of Highways,
six-inch HDPE perforated pipe suitable for H2O loading shall be laid
in three-fourth-inch crushed stone under all curbs as shown on Figure
8B.[2] The underdrain shall be so graded that any water under
the curbs will drain to the nearest catch basin where the underdrain
shall be connected.
[2]
Editor's Note: Figure 8B is included at the end of this chapter.
A.Â

in accordance with Figure 11A, except in the case of a new street
intersecting an existing narrow road when it shall be modified as
shown on Figure 11B.
A.Â
The developer
shall furnish and install a four-way street name sign at every intersection
made by the streets he constructs. Signs and posts shall conform dimensionally
to Figure 12A and otherwise in their design and installation to the
standards established within the NYSDOT Manual of Uniform Traffic
Control Devices (MUTCD).
B.Â
The developer
shall also furnish and install stop signs, stop bars, dead end signs,
and all other regulatory or advisory signs that may be required on
the streets he constructs. Signs and posts shall conform dimensionally
to Figure 12B and otherwise in their design and installation to the
standards established within the NYSDOT Manual of Uniform Traffic
Control Devices (MUTCD).
A.Â
Monuments shall be set on all right-of-way lines of
streets, at all street intersections, angle points, points of curve
and subdivision corners and all easements or where ordered by the
Town Superintendent of Highways. There shall be a clear foresight
and backsight to adjacent monuments on the right-of-way line or lines
on which a monument is set.
B.Â
Monuments shall be 36 inches long, five inches square
at the top tapering to six inches square at the bottom, and shall
have centered in the top a three-eighths-inch or one-half-inch drill
hole, a three-eighths-inch or one-half-inch steel rod slightly protruding
or some other permanent and satisfactory center mark. Monuments shall
be of cut granite, free from imperfections, or of concrete and as
approved by the Highway Superintendent. See Figure 13.
C.Â
Monuments shall not be set before final grading has
been completed, nor shall they be set while frost is in the ground.
They shall be set so that the top is flush with the finished grade.
They shall be so set and tamped as to prevent settlement or shifting.
D.Â
The developer's engineer and/or licensed land surveyor
shall certify that the location of all monuments is accurate before
acceptance of the street by the Town Board.
A.Â
The developer shall dedicate to the Town, by recordable
instrument, all easements as shown on the approved plan.

30 feet and shall include the right to enter upon said property for
the purposes of installing, maintaining and repairing the pipe or
pipes as placed in such easements. It is the policy of the Town that
all storm drainage be enclosed in drainage pipe, and all easements
shall contain a provision for the right to install underground pipes
and to discharge stormwater therein. The developer shall install,
a minimum of 20 feet from the catch basin into the easement, pipe
of sufficient size to provide for present and future runoff.
C.Â
Where it is proposed that stormwater be drained from
the street or highway or from other lands of the developer to the
perimeter' of the developer's property, easements shall be provided
in recordable form and free and clear of all liens from the adjoining
owners, permitting the discharge of stormwater drainage onto such
adjoining lands.
D.Â
Where
it is proposed that stormwater be drained from the street or highway
or from other lands of the developer depicted on a subdivision plat
or site plan and either retained or detained within a stormwater pond,
adequate fencing of any stormwater pond shall be designed and installed
as a required improvement. Such fencing shall be of post-and-rail
design with associated welded wire mesh as shown on Figure 14.
E.Â
The developer shall provide an attorney's certificate
of title indicating that the above-mentioned easements and rights
to discharge surface water are free and clear of all liens.
In those situations where the conditions of soils and topography
and the amount of stormwater runoff to be accommodated combine to
make possible the conveyance of stormwater within either open ditches
or swales, the applicant shall submit design plans for the proposed
open ditchers or swales, including associated rip rap material and
construction specifications, for review and approval by the Town Highway
Superintendent and the Town Engineer. The design plans shall be accompanied
by engineering demonstration of both hydraulic capacity and the adequacy
of proposed stabilization measures.
Stormwater discharge from roof and cellar drains
shall in no case be allowed to flow onto the street right-of-way.
With the approval of the Town Superintendent of Highways and the Town
Engineer, in writing, these drains may be connected to the street
stormwater pipe. Such connections must however be made prior to the
start of fine grading of the streets.
Wherever a temporary or permanent dead end is
allowed on a subdivision street, a turnaround shall be constructed.
This turnaround and associated right-of-way shall take the form of
a circle and shall be designed and constructed as shown on Figure
15. The temporary type of construction shall be used only when authorized
by the Town Planning Board because of the foreseeable future extension
of the street. The circular-shaped turnaround shall be completely
paved with no center island.
Streets shall be so designed that finished tangent
curves will not be less than 1% or more than 10%. Every change in
grade shall be effected with a vertical curve of sufficient length
to ensure adequate stopping sight distance and to provide for smooth
transition. These vertical curves shall be designed in accordance
with the graph shown on Figure 16 which is based on New York State
standards for speeds of 30 miles per hour. Figure 17 further depicts
minimum standards for side street approach grades.
The developer shall furnish and install guide rail on any public
or private subdivision street as deemed required by the Town Superintendent
of Highways and/or the Town Engineer upon application of the design
guidelines set forth within the MSHTO Roadside Design Guide and Chapter
10 of the New York State Highway Design Manual. In the case of suburban
or rural-type streets with less than 400 vehicles AADT, Guidelines
for Geometric Design of Very Low Volume Roads, AASHTO 201, may also
apply. See Figure 18 for depiction of preferred guide rail design,
recommended clear zone and critical (i.e., maximum) side slope conditions
that should be avoided or otherwise mitigated through installation
of guide rail.
No snow removed from adjacent driveways or other developed areas
shall be deposited upon the right-of-way of either a public or private
street or within any Town easement area unless such easement area
is specifically designated on the approved subdivision plat and/or
site plan for snow storage.
The final decision as to the interpretation
of any part of these street specifications shall rest with the Town
Superintendent of Highways.
In the event that any part or parts of these
street specifications for subdivisions or of any ordinance or regulations
which may govern or otherwise affect them is for any reason modified
or invalidated, the other portions of said specifications not affected
thereby shall remain in full force and effect.
A.Â
The developer shall afford the Town Superintendent
of Highways the opportunity to inspect the work in order that he,
the Superintendent, may assure himself that these minimum specifications
are being complied with. Such inspections shall occur at the following
listed places in order of construction, and the developer shall give
the Town Superintendent of Highways at least two days' notice of such
expected completions and shall not proceed to the next order of work
until the Town Superintendent of Highways has approved the work inspected.
(1)Â
Upon completion of the subgrade.
(2)Â
Upon completion of the foundation course, at which
time the developer shall furnish the Town Superintendent of Highways
with men and equipment to dig, or have dug, test holes to establish
and confirm the depth and quality of the foundation course.
(3)Â
Upon beginning of paving operations.
B.Â
The Town Superintendent of Highways, or his representatives,
shall be given access to the work at all times in order that he may
inspect the work as it progresses.
In the event that these street specifications
are in conflict with other rules and regulations in effect in the
Town in the matter of the design and construction of either public
or private streets, these street specifications will be considered
to supersede all others.
