[HISTORY: Adopted by the Town Board of the
Town of Wawayanda 11-1-1990 by L.L. No. 4-1990. Amendments noted where
applicable.]
It is the purpose of these specifications to
establish minimum acceptable standards for street construction for
subdivisions in the Town of Wawayanda which have been established
to conform to legal requirements in the State of New York. The 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 sidewalks, monuments and signs. Dedication
of the right-of-way will not be accepted until the developer's professional
engineer or qualified licensed land surveyor and the Town Superintendent
of Highways shall have certified to the Town Board, in writing, that
the construction of the street or road has been completed in accordance
with the approved plans and specifications that follow, that the total
right-of-way area has been cleared of all debris and that all construction
has been completed in a workmanlike manner. When new road rights-of-way
are offered to the Town for dedication, three copies of the final
plan and deed description of each right-of-way shall be submitted
to the Town's Superintendent of Highways for approval and title, showing
no liens or encumbrances when submitted to the Town Attorney.
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 specifications.
A.
A plan 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 roadways,
storm drainage, including culverts and other drainage structures,
as well as the location of all easements, utilities and monuments.
The plans shall also indicate the owner of the property and the name
of the developer, if other than the owner. One copy each of the plans
shall be submitted to the Town Superintendent of Highways and to the
Town Engineer at the time of application to make such a Town road
and to the County Superintendent of Highways or the New York State
Department of Transportation permit agent when said proposed street
drains toward, intersects or may otherwise affect a county or New
York State highway. Additional copies will then be submitted to the
Town Planning Board, or Town Board, if applicable, for review and
approval under the applicable subdivision regulations of the Town.[1] Such roadway must not be subject to any right or easement
in others which will in any way interfere with its use as a road at
all times. Such roadway must be granted free of all encumbrances to
the Town by a full covenant and warranty deed containing the correct
metes and bounds description as shown on the approved map. The 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. Filing
fees must be paid by the applicant. An offer of dedication in form
approved by the Town Attorney and an executed deed shall be delivered,
to be held in escrow pending final acceptance.
B.
Permanent and temporary easements must be furnished
in said deed granting to the Town the right to maintain 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 30 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 shall be cleared of all trees, rock formations, buildings, walls
and any such things that would endanger those using the roadway. The
cost of the removal of such obstructions shall be borne by the person
or firm proposing such road.
A.
Plans shall not be altered or amended after having
been approved by the Town Superintendent of Highways and the Town
Engineer during the plan review process unless amended plans are resubmitted
by the owner and approved. However, if during construction conditions
arise that were unaccounted for during the original design, the developer,
at his own expense, will be required to submit further amended plans
to be approved by the Town Superintendent of Highways and the Town
Engineer.
B.
The developer, at his own expense, shall provide additional
storm drainage facilities or utilities if, during the course of construction,
in the opinion of the Town Superintendent of Highways and/or the Town
Engineer, such additional structures or facilities are necessary to
prevent any need for future installations of utilities or culverts
within the pavement area, to assure the durability of the pavement
and to assure future maintenance of the right-of-way or for the welfare
and safety of the public. The Town Board may vary the requirements
of such an order where there are practical difficulties in the way
of carrying out to the letter such an order unless such variance conflicts
with the provisions of a Town or drainage map, in which event, the
official map shall prevail. If construction of said road has not been
started within one year of the date of final approval by the Town
Planning Board, or Town Board, if applicable, plans shall be resubmitted
and approved as above.
[Amended 5-3-2007 by L.L. No. 3-2007]
A.
Prior to the start of construction of any street,
the developer shall provide the following to the attorney for the
Town for review and approval: a developer’s agreement concerning
the proposed construction, an irrevocable offer of dedication and
proposed deed to the Town signed by the developer (or the owner of
the property, where the owner is not the developer) for the street
and improvements, and a preliminary title insurance policy. In addition,
the developer shall deposit with the Town Clerk or the chief fiscal
officer of the Town performance security in the form of an irrevocable
letter of credit in form and amount approved by the Attorney for the
Town and by the Town Board or cash or a certified check drawn upon
a national or state bank, payable at sight to the Town Board, in an
amount to be determined by the Town Board, guaranteeing that:
(1)
Within two years of the issuance of the first building
permit for the property to be served by the street, the developer
will complete all of the construction within the right-of-way, including
roadways, shoulders, curbs, sidewalks, if any, gutters, if any, storm
drainage, etc., and all utilities, including hydrants, and all house
connection stub outs for each lot in accordance with the approved
plans and specifications, and further guaranteeing that all claims
for labor and materials in connection with said construction will
be paid in full prior to acceptance of said street for dedication
to the Town.
(2)
Upon certification by the developer’s professional
engineer and by the Town Superintendent of Highways and the Town Engineer
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 guarantee of dedication
shall apply to the owner of the property, as well as the developer,
where the two are not synonymous.
(3)
No residential unit may receive a certificate of occupancy until all improvements described in § 158-5A(1) above have been completed to the satisfaction of the Town Superintendent of Highways and the Town Engineer [except for the top course of paving for the street and landscaping within the street right-of-way, and only if the owner and/or developer has posted performance security in accordance with the requirements contained in § 158-5A(1) above].
(4)
In the event the developer does not complete all improvements described in § 158-5A(1) above (including the top course of paving for the street and landscaping within the street right-of-way) within two years of the issuance of the first building permit for property to be served by the street, the Town may declare the developer to be in default and choose to accept the offer of dedication and record the deed to the street, in which case the performance security posted by the developer will immediately be released to the Town for the completion of the street and improvements, and the developer will have no claim against that portion of the performance security required by the Town to complete the street and improvements.
B.
As guarantee for the above requirements, the developer shall deposit with the Town Clerk or the Chief Financial Officer of the Town an irrevocable letter of credit, cash or a certified check all as described in Subsection A. The minimum total amount of the guarantee shall be determined by the Town Board after recommendation of the attorney for the Town and the Town Engineer.
A.
Prior to acceptance by the Town of the dedication
of the street, the developer shall deposit with the Town Clerk or
with the chief fiscal officer of the Town an irrevocable letter of
credit in form and amount approved by the attorney for the Town and
by the Town Board, or by cash or a certified check drawn upon a national
or state bank, payable at sight to the Town Board, in an amount to
be determined by the Town Board, guaranteeing that for a period of
24 months 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 forth 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 outside the right-of-way. After street acceptance
and 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.
[Amended 5-3-2007 by L.L. No. 3-2007]
B.
The amount of the maintenance security shall be at
least equal to 20% of the original amount of the performance security.
C.
Subsequent to the acceptance of the dedication of
the street and after receipt of the maintenance security, the Town
Board may release all or part of the performance security.
[Amended 5-3-2007 by L.L. No. 3-2007]
A.
The Town Planning Board or the Town Board, if applicable,
with the recommendations of the Town Superintendent of Highways and
the Town Engineer, as applicable, shall determine and designate into
which of the following classifications each proposed subdivision street
falls on the basis of one or more of the criteria hereinafter set
forth:
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.
[Amended 5-3-2007 by L.L. No. 3-2007]
Determining criteria shall be as follows:
A.
Collector streets. The proposed street:
(1)
Is the direct and logical continuation of a street
that carried 500 or more cars during a twelve-hour period as shown
by the latest traffic count;
(2)
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)
Is the principal collector for 300 or more homes in
the neighborhood; or
(4)
Could logically be expected to become a collector
street because of future construction or other foreseeable circumstances.
B.
Commercial streets. The proposed street:
(1)
Is in an area zoned for commerce or industry;
(2)
Is on or so close to the dividing line between a residential
and a commercial or industrial area that it may reasonably be expected
to carry commercial or industrial traffic;
(3)
Creates a shorter and more convenient route between
a commercial or industrial area and an arterial street; or
(4)
For any other reason may be expected to carry commercial
or industrial traffic.
C.
Suburban roads. The proposed street:
(1)
Will generally serve subdivisions of 25 lots or more;
(2)
May be a dead-end street with a one-hundred-twenty-foot-diameter
cul-de-sac, a loop (through street) or a street connecting two existing
Town, county or state highways; or
(3)
Shall not be or be reasonably expected to become a
through commercial or collector street.
E.
Private roads.
(1)
General requirements.
(a)
Private roads shall only be utilized or proposed
for approval to serve lots for single-family use.
(b)
The Town Planning Board shall not approve the
use of a private road in any subdivision if it is determined that
the use of said private road is not consistent with the health, safety,
welfare and convenience of the proposed users of the road and the
people of the Town in general.
(c)
To the extent practicable, the owner of any
lot having access only to an approved private road shall be the owner
of the portion of the private road adjacent to his or her lot to the
center line of said private road unless such other ownership provisions
have been shown on the filed subdivision plat, as approved by the
Planning Board.
(d)
Responsibility for maintenance.
[1]
Where a subdivision plat containing a private
road is approved by the Planning Board and filed with the Orange County
Clerk, such subdivision plat shall contain a note clearly stating
that the subdivision contains a private road which the Town has no
responsibility to maintain, provide services for nor make any improvements
to; all such costs shall be borne by the property owners using said
road in accordance with the terms of a maintenance declaration or
agreement, as referenced herein below.
[2]
All private roads will have provisions for the
maintenance of the private road, drainage facilities and other improvements
incorporated in a maintenance declaration or agreement, approved by
the attorney for the Town and by the attorney for the Planning Board
which shall be recorded in the Orange County Clerk’s office
at the time of the filing of the subdivision plat and prior to the
transfer of any subdivision lot (with a copy of the recorded document
submitted to the Town Clerk for file).
[3]
A private road may not be offered for dedication
to the Town unless the owners of the private road shall first have
caused it to meet or exceed the specifications set forth in this chapter
for a public street for acceptance by the Town.
(e)
The Planning Board shall require, as a condition
of approval, that a performance guarantee in form and amount satisfactory
to the attorney for the Town and the Town Board be posted with the
Town to guarantee the installation of the private road and associated
improvements.
(2)
Construction specifications and additional requirements.
(a)
If the Planning Board shall authorize the construction
of a private road in accordance with the standards set forth in this
chapter, said private road shall conform to the minimum standards
set forth below and private road specifications attached:
[1]
The private road will have the subbase prepared
and compacted to maximum density (minimum 90%). Where grade alteration
is required, the same shall be by use of suitable foundation course
material, compacted to maximum density (minimum 90%). Material shall
be certified by the design engineer as suitable for the purposes indicated;
[2]
A private road shall not be less than 20 feet
in width (finished surface) and shall have, in addition, shoulders
three feet in width on both sides of the road, which shoulders shall
be compacted roadway base and top material (full depth) and shall
also have a two-foot roadway drainage swale adjacent to each shoulder.
The swale shall be grass lined or stone lined, as deemed appropriate
for the site condition;
[Amended 3-4-2021 by L.L. No. 2-2021]
[3]
The right-of-way reserved for all private roads
shall not be less than 50 feet in width; rights-of-way for culs-de-sac
shall not be less than 120 feet in diameter;
[4]
If any private road shall end in a cul-de-sac,
said cul-de-sac shall have a finished surface being not less than
100 feet in roadway diameter. Alternate layouts will be considered,
subject to Planning Board approval, when site conditions make construction
of the full size cul-de-sac impractical;
[5]
No portion of any private road shall have a
grade exceeding 12%;
[6]
All side slopes adjacent to or part of any private
road shall not be steeper than a slope of two to one. A “one
on two slope” is defined as a drop of one unit of distance vertically
for every two units of distance horizontally;
[7]
All private roads will be required to have a
street name approved by Orange County 911 and the Town Board;
[8]
No permanent or temporary private roads will
be allowed off culs-de-sac; and
[9]
An emergency vehicle turnaround shall be constructed
at the end of all private roads.
(b)
An index shall be kept by the Town Clerk of
all subdivisions approved by the Planning Board which contain private
roads. Said subdivisions shall be indexed by name, Tax Map designation(s)
and date of approval.
[Amended 5-3-2007 by L.L. No. 3-2007[1]]
A.
The pages immediately following show the cross sections
of each of the classifications for subdivision streets.[2] These give the required design, dimensions and construction
details which are acceptable for each classification.
[2]
Editor's Note: Said cross sections are included
at the end of this chapter.
C.
The developer shall design and construct streets which
shall conform to both the general and the specific specifications.
D.
The subbase and foundation course shall be compacted
mechanically to 90% modified Procter Dry Density, certified to by
a professional engineer licensed by the State of New York. In lieu
of such compaction, the subbase shall lay for at least the four-month
winter period of December, January, February and March, in its entirety,
after which it must be inspected and approved by the Town Superintendent
of Highways and the Town Engineer.
E.
In addition, the developer shall design and construct
streets which shall conform to any additional requirements of the
Town Superintendent of Highways and the Town Engineer. The final decision
as to the interpretation of any part of these street specifications
remains with the Town Superintendent of Highways, in consultation
with the Town Engineer.
[1]
Editor's Note: This local law also repealed
former Table 1, Summary Table of Street Specifications, which had
been included at the end of this chapter.
The following list sets forth the proposed means
of access that shall be followed by contractors working on construction
lots. It should, of course, be pertinent to any construction access
from a present or to-be-dedicated Town street.
A.
Access to the lot shall be at a single point across
the shoulder, curb, ditch or other roadside feature.
B.
The access shall be over a twenty-foot-wide section
of shale or other suitable stone placed at the future driveway point
in order to prevent rutting or other damage to shoulder, curbs or
ditches.
C.
If this access crosses a ditch, a culvert pipe shall
be installed to allow passage of normal storm drainage without blocking
this drainage or causing it to flow into the street.
D.
Tracked vehicles and those with cleated feet (cranes
and backhoes) are to be prohibited from working on streets that have
had paved base course or topcoat applied. These vehicles are to be
unloaded so that they work on the lots, not in the streets.
E.
Tracking mud and dirt onto paved streets is to be
kept to a minimum. Excessive mud and dirt is to be cleaned off of
the streets by the contractor.
F.
If damage is done to the street, shoulders or curbs
on the Town right-of-way and this damage is not repaired, money to
do pavement replacement or other repair of such damage shall be received
before a certificate of occupancy is issued.
[Amended 12-28-2010 by L.L. No. 3-2010]
A.
Permanent concrete, copperweld, standard aluminum (New York State
Department of Transportation) or #6 (3/4 inch diameter) steel rebar
24 inches in length monuments shall be set on right-of-way lines of
streets, at all intersections, angle points, points of curvature,
beginnings and ends of streets and at all subdivision corners and
angle points where designated on the final subdivision plat. There
shall be a clear foresight and backsight to adjacent monuments on
the right-of-way lines, which may require additional monuments on
the line. All monuments shall exist on completion of the construction
of the streets.
B.
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
so set and tamped as to prevent settlement or shifting.
C.
If a monument should be located in a rock ledge, the surface shall
be stripped and a #6 (3/4 inch diameter) steel rebar drilled into
the ledge.
D.
The developer's engineer or licensed land surveyor shall certify
that the location of all monuments is accurate before acceptance of
the street by the Town.
Where surface water from streets must lead through
other than right-of-way gutters and storm drains or existing stream
channels outside of the right-of-way, permanent drainage easements
having a minimum width of 30 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,
as required by the New York State Environmental Quality Review Act.[1] Natural stream or ditch channels shall have a minimum
of fifty-foot-wide permanent easements, and these shall be shown on
the proposed plans of the subdivision. All permanent easement lines
shall be monumented as rights-of-way.
[1]
Editor's Note: See Environmental Conservation
Law § 8-0101 et seq.
The developer shall complete the shaping of
the road right-of-way, streams, ditches and easement areas to the
line and grade as shown on the approved plans and as otherwise may
be required by the Town Superintendent of Highways and the Town Engineer.
In the construction of the roadway, all topsoil, loam, rocks 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. Such fills shall be made in
layers of not more than 12 inches each and properly compacted with
a ten-ton roller or equivalent.
A.
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.
B.
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.
The subgrade shall be shaped to line and grade with
no depressions. The subgrade 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. All slopes and sidewalk
areas shall be graded before the foundation course is laid. All loose
and exposed stones will be removed.
A.
Before fine grading or construction of curbs and sidewalks
is started, all storm and sanitary sewers and all utilities within
the street right-of-way, including house connections for existing
and future homes and hydrants, shall have been installed in accordance
with approved final plans to the satisfaction of the Town Superintendent
of Highways and the Town Engineer. All fill and backfill shall have
been thoroughly compacted to the satisfaction of the Town Superintendent
of Highways and the Town Engineer.
B.
Before fine grading or construction of curbs and sidewalks
is started, all heavy trucking for site construction purposes shall
have been completed.
C.
Fine grade shall conform to the required 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.
After the fine grade and all curbs have been constructed
to the satisfaction of the Town Superintendent of Highways and the
Town Engineer, 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 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 to exceed 2/3 the thickness of the compacted foundation
course. Ninety percent 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.
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
and/or the Town Engineer 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.
After compaction, the foundation course shall be fine
graded to an elevation allowing for the asphaltic concrete pavement
courses and approved by the Town Superintendent of Highways and the
Town Engineer. A minimum of three months shall be allowed for the
street to settle and compact before pavement shall be constructed.
Stakes with final line and grade shall be maintained by the developer
at all times to check the foundation course as well as the 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 and the Town Engineer. Plans
for any drainage structure, when existing or proposed, shall be submitted
in detail to the Town Superintendent of Highways and the Town Engineer
for approval. The minimum grade of any drainage pipe or culvert shall
be based on providing scouring velocities at low flow. The approved
plans shall show invert elevations of the inlet and outlet of all
drainage structures, as well as the length, slope and material of
the structure of pipe. 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 other than driveway pipe (twelve-inch
minimum) shall be less than 15 inches in diameter.
B.
Pipe for culverts may be reinforced concrete, fully
coated aluminized corrugated metal or fully coated bituminous coated
corrugated metal pipe with paved invert or corrugated polyethylene
pipe (smooth flow), as approved by the Town Highway Superintendent
and/or the Town Engineer. All culverts shall have flared end sections
or headwalls.
C.
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 four inches, but at least six inches
over rock, shall be laid in line with grade prior to laying the pipe.
No rock over three inches in thickness 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 of the trench.
D.
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.
E.
The pipe shall be laid to true line and grade on the
prepared bed of the trench. All connections for corrugated metal pipe
shall consist of twelve-inch corrugated metal bands lapping on equal
portions of the sections to be connected. All joints in making field
connections of reinforced concrete pipe shall be filled with portland
cement mortar. 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 18 inches which shall be mechanically tamped. In no
case shall the top of any drainage pipe be less than 18 inches below
the finished center-line grade of pavement or 12 inches below the
grade at the edge of pavement or bottom of gutter.
F.
All drainage structures shall be of a size sufficient
to carry the rate of natural water runoff, 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.
A.
Storm drain and culvert pipe shall be of either fully
coated corrugated metal with paved invert, reinforced concrete or
corrugated polyethylene (smooth flow) with a minimum diameter of 15
inches for initial street crossings and a minimum diameter of 18 inches
for all other storm drainage.
B.
Round corrugated metal pipe shall conform to Item
IIG of Part III, Section 707, of Standard Specifications, Construction
and Materials, New York State Department of Transportation, January
1985, or as later revised.
(1)
All corrugated metal pipe shall be made of copper
steel metal.
(2)
All corrugated metal pipe shall be fully paved with
bituminous material to a depth of not less than 1/8 inch measured
over the crest of the corrugations of the inside circumference, with
paved invert.
(3)
All collars or connecting bands shall be at least
12 inches wide and shall be furnished with bolts at least six inches
long.
C.
Reinforced concrete pipe shall conform to the standard
specifications for reinforced concrete culvert pipe adopted by the
American Society for Testing Materials and designated as C76-59T,
Class III. All reinforced concrete pipe shall be manufactured with
slip joints or bell-and-spigot joints. Each piece of reinforced concrete
pipe shall be marked with the specification number and the date of
manufacture.
D.
Corrugated polyethylene pipe with smooth interior
and fittings shall be manufactured from the density polyethylene resin
which shall meet or exceed the requirements of Type III, Category
4 or 5, Grade P33 or P34, Class C, per ASTM D1248. The nominal size
of the pipe is based on the nominal inside diameter of the pipe. The
tolerance on the specified inside pipe diameter shall be +3%, -1 1/2%
or 1/2 inch, whichever is less. The pipe shall have a minimum pipe
stiffness at 5% deflection of 40 pounds per square inch for eighteen-inch
pipe. The pipe shall be joined by split corrugated couplings at least
seven corrugations wide and exceeding the soil tightness requirements
of the American Association of State Highway and Transportation Officials
Standard Specifications for Highway Bridges, Section 23.
A.
With the approval of the Town Superintendent of Highways
and the Town Engineer, open ditches may be used in lieu of storm drain
pipes when the grade of the land traversed is flat or when it is desirable
to drain and dry up the surrounding area.
B.
Open ditches shall be constructed in accordance with
Figure 5[1] of these specifications, but in no case shall the grade
of an open ditch be less than 1%. Riprap, when called for on the final
plans or as determined in the field to be necessary by the Town Highway
Superintendent and/or the Town Engineer, shall consist of field stone
or rough, unhewn quarry stones as nearly cubical in form as is practicable,
placed upon a slope not steeper than 1:2 and so laid that the weight
of the large stones is carried by the soil and not by the stone adjacent.
All stones shall weigh between 50 and 150 pounds each, and at least
60% of them weigh more than 100 pounds each. In certain specific cases,
when determined by the Town Highway Superintendent and the Town Engineer,
riprap shall meet the New York State Department of Transportation
floodway specifications.
[1]
Editor's Note: Figure 5 is included at the end of this chapter.
C.
The largest stones shall be placed first, roughly
arranged and in close contact. The spaces between the larger stones
shall be filled with spalls of suitable size. Stabilization of the
ditch shall be such that scouring by calculated flows does not occur.
D.
Whenever a drainpipe enters an open ditch, the bottom
and sides of the ditch shall be riprapped for a distance determined

Editor's Note: Figure 7 is included at the end of this chapter.
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 and the Town Engineer
shall be installed. Perforated pipe or porous wall piping 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 amounts deemed necessary by the Town Superintendent of Highways
and the Town Engineer.
A.
Roof, footing and cellar drains shall in no case be
allowed to flow directly 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 piped to existing stormwater drains, if any, to
which they will be connected above the horizontal center line of the
pipe only. Such drains must be installed prior to the start of the
application of the foundation course. Drains from the sanitary sewers
or septic tanks will not be permitted to flow into road ditches or
storm drains under any circumstances.
B.
Any such existing drains shall be changed within two
years to a conforming drain because they create potential hazards
to public health, safety and welfare. Said two-year period shall commence
upon written notification by the Town Superintendent of Highways.
Streets shall be so designed that furnished
tangent grades will not be less than 1% nor 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 8 of these specifications,[1] which is taken from New York State standards for speeds
of 30 miles per hour.
[1]
Editor's Note: Figure 8 is included at the end of this chapter.
On through, commercial, suburban or rural streets,
six-inch portland cement concrete curbs shall be constructed on both
sides of the street as shown in Figure 9,[1] prior to laying street pavement to the dimensions and
specifications shown in Table 1, Summary Table of Street Specifications.[2] A base course of eight inches of run-of-bank gravel, tamped
and free of stone over two inches in thickness, shall be laid under
all curbing. Concrete having a compressive strength 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 or scaled or has become damaged
in any way by the developer before and within the twenty-four-month
maintenance period after dedication. Curbs shall be depressed four
inches at all driveways. All necessary driveway entrances within a
subdivision shall be constructed at the time of construction of the
curb. Stone curbs or precast curbs may be substituted on approval
of the Town Superintendent of Highways and the Town Engineer.

Editor's Note: Table 1 is included at the end of this chapter.
A.
The developer shall design, lay out and construct
all driveways, both within and without the limits of the right-of-way,
with sufficient sight distance. 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. The elevation of
the driveway at the right-of-way line shall be the same as the street
center line elevation. All driveways shall have a six-inch run-of-bank
gravel foundation course from the curb to the right-of-way line and
no less than a four-inch asphaltic cement wearing course from the
curb or street pavement line to the 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/or the Town Engineer prior
to the issuance of a certificate of occupancy. Only driveway points
are to be used for contractor access to each building lot.
Commercial driveways shall be designed in accordance
with anticipated heavy traffic usage, as determined by the Town Superintendent
of Highways and the Town Engineer.
Where sidewalks are required by the Planning
Board, or Town Board, if applicable, the developer shall construct
four-inch-thick reinforced portland cement concrete sidewalks on both
sides of streets as shown on Figures 1, 2, 3 and 4.[1] Concrete shall be of a one-to-two-to-three mix, air-entrained
with Durex or equal, one course, properly screened, floated and broom-finished
to true grade to the satisfaction of the Town Superintendent of Highways.

Editor's Note: Figures 1, 2, 3, 4A and 4B
are included at the end of this chapter.
A.
All intersections with existing Town or county roads
and intersections within the development shall be constructed with
the edge of the pavement having a radius of 20 feet minimum and 35
feet maximum, as determined by the Town Superintendent of Highways
and the Town Engineer. All intersecting streets shall have a minimum
horizontal sight distance of 400 feet in each direction. Exceptions
for less than 400 feet will 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 will show the proposed type, length and diameter
of pipe and drainage flow along said road. The pipe will 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 be no more than one inch per foot from the edge
of the shoulder of the Town or county road to the right-of-way or
road line of said road. The County Superintendent of Highways shall
be notified of all intersections with county roads for approval of
location, grade and drainage structures.
Whenever a temporary or permanent dead end is
allowed on a subdivision street, a turnaround shall be constructed.
This turnaround shall take the form of a tee or a circle as required
by the Town Planning Board, or Town Board, if applicable, and shall
be constructed as shown on Figures 15 and 16.[1] The temporary type of construction shall be used only
when authorized by the Town Planning Board, or Town Board, if applicable,
because of the foreseeable future extension of the street.
[1]
Editor's Note: Former Figures 15, Minimum
Standards for Turnarounds, and 16, Standards for Turnarounds, were
repealed 5-3-2007 by L.L. No. 3-2007.
The developer, at its own cost and expense,
shall furnish and install four-way street name signs at every street
intersection made by the street he constructs. Traffic control signs,
as necessary for public safety, shall be furnished and installed by
the developer as directed by the Town of Wawayanda. Signs and posts
shall conform to the standards established by the Town Board by resolution.
A.
Base course. After the foundation course has been
completed to the satisfaction of the Town Highway Superintendent and
the Town Engineer, asphaltic concrete conforming to the current specifications
of the New York State Department of Transportation shall be uniformly
spread by a self-propelled mechanical spreader equipped with tamping
bars and heating unit and in sufficient depth so as to provide a finished
compacted thickness after rolling equal to that specified. The base
material in place shall be thoroughly rolled with a ten-ton vibratory
roller.
B.
Binder course. After the base course has been thoroughly
cured and cleaned of all foreign material, an asphaltic concrete binder
course shall be uniformly spread by a self-propelled mechanical spreader
equipped with tamping bars and heating unit and in sufficient depth
so 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 vibratory roller.
C.
Wearing course. After the binder course has been completed
and thoroughly cleaned of foreign material and a tack coat of asphalt
emulsion has been applied to the surface at a rate of 1/10 to 1/20
gallon per square yard, a final wearing course of fine asphaltic concrete
shall be uniformly spread by a self-propelled mechanical spreader
equipped with tamping bars and heating unit and in sufficient depth
so as to provide a finished compacted thickness after rolling of not
less than 1 1/2 inches. The fine wearing course in place shall
be thoroughly compacted with a ten-ton vibratory roller.
D.
Joints. Extreme care shall be exercised in the placing
of asphaltic 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.
Temperature and seasonal requirements.
(1)
The bituminous mixture shall be produced, delivered
to the work site and incorporated into the work within (20º F.
of the temperature specified by the Engineer but within the mixing
and placing temperature range of 250º F. to 325º F.).
(2)
Bituminous plant mix shall not be placed on any wet
surface or when surface temperature is less than specified in the
table below or when weather conditions otherwise prevent the proper

for both pavement surface and shoulder surface courses. Paving shall
be discontinued as soon as the temperature falls below the requirements.
(5)
Bituminous paving mixtures for curbs, driveways, sidewalks,
gutters and other incidental construction shall be placed on surfaces
having a temperature of 45º F. or greater unless otherwise authorized
by the Engineer. Placing of these items is not subject to seasonal
limitations.
Damage and failure to repair any portion of
the street or highway, following acceptance of the same by the Town,
shall preclude release of the performance and/or maintenance bond
to the developer.
Final decision as to the interpretation of any
part of these street specifications shall rest with the Town Superintendent
of Highways. He shall have the authority to modify the requirements
of these specifications when, in his opinion, conditions make it impracticable
to follow the strict letter of these specifications or when conditions
make it unnecessary to do so, such as, for example:
