It is the purpose of these specifications to
establish minimum acceptable standards of street construction for
subdivisions or other new public roads to be constructed in the Town
of Wallkill, including, but not limited to, width, design, drainage,
the construction of base and pavement, curbs and sidewalks, monuments
and signs. Dedication of the right-of-way will not be accepted until
the Town Engineer or the Commissioner of Public Works shall have advised
the Town Board, in writing, that the construction of the street or
streets has been completed in accordance with the approved plans and
the specifications which follow, and recommended acceptance of dedication.
In the written certification, as required above,
the Town Engineer and/or the Commissioner of Public Works 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.
A plan of the proposed street shall be prepared
by a qualified engineer 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,
and the location of easements and utilities. The plan shall be submitted
to the Commissioner of Public Works and the Town Engineer, and then
to the County Superintendent of Highways when any street drains toward
or may otherwise affect a county highway, and then shall be returned
to the Town Planning Board for review and approval under the applicable
subdivision regulations of the town. Such plans so submitted shall
not be altered or amended after having been approved by the Planning
Board, unless amended plans are resubmitted and approved as above.
However, the developer shall, at his own expense, provide additional
storm drainage facilities as may be ordered by the Commissioner of
Public Works if, during the progress of the work, in the opinion of
the Commissioner of Public Works, the Town Engineer and/or the County
Superintendent of Highways, such additional structures or facilities
are necessary to assure the durability of the pavement, the future
maintenance of the right-of-way or the welfare or safety of the public,
except that the Town Planning Board may vary the requirements of such
order where there are practical difficulties or unnecessary hardships
in the way of carrying out the strict 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
has not been started within two years from the date of final approval
by the Town Planning Board, plans shall be resubmitted and approved
as above.
A.
Prior to the start of construction of any improved
street, the developer shall deposit with the Town Clerk a letter of
credit or 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:
(1)
That within two years the developer will complete
all the construction within the right-of-way, including the roadway,
shoulders, sidewalks, curbs, gutters, storm drainage, etc., and all
utilities, including hydrants and house connections for each lot,
in accordance with the approved plans and these specifications.
(2)
That, upon certification by the Town Engineer or by
the Commissioner of Public Works, 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.
B.
As a surety for the performance of the above requirements,
the developer shall deposit as heretofore set forth a letter of credit,
surety bond, negotiable government bonds, cash or certified check,
the minimum total amount of which shall be calculated by the developer's
engineer and submitted to the Town Engineer and Commissioner of Public
Works for review and approval. The amount of surety shall not be less
than 100% of the public improvement costs, and estimates of these
costs shall be calculated utilizing current costs for municipal construction
and prevailing wage rates.
(1)
If a building permit is requested to be issued prior
to completion of public improvements, the surety shall be in the form
of cash or certified check.
C.
Prior to being deposited with the Town Clerk or chief fiscal officer as described in Subsection A above, surety instruments shall be submitted to the attorney for the town for review and approval. When deposited with the Town Clerk or chief fiscal officer, surety instruments shall be accompanied by a written acknowledgment by the attorney for the town that the instrument is acceptable.
D.
No surety instruments shall be allowed to expire until
the work is complete, the improvements have been dedicated to the
town and the Town Board has passed a resolution allowing expiration
of the surety. Each surety instrument shall include language acknowledging
that the instrument shall remain in effect until the above conditions
are met.
[Amended 3-23-2006 by L.L. No. 3-2006]
The owner/developer is responsible for the payment of all inspection and as-built drawing fees for work required in § 249-42 C(2). Initially, an inspection fee of a percentage to be set by resolution of the Town Board, of the amount of the construction costs shall be paid to the town prior to the time that the Chairman of the Planning Board signs the final plat and the start of any site improvement work. The inspection fee will be held in escrow by the town (project inspection escrow fund) and will be used to pay any and all town engineering, legal and staff expenses associated with the inspection, as-built drawing preparation and dedication of the improvements. If during the construction of the improvements the project inspection escrow fund is reduced to a level that the Commissioner of Public Works or the Town Engineer deems is insufficient to complete the required inspections, the owner/developer shall, within 30 days notification by the Commissioner of Public Works, furnish such additional inspection fees to the town. If said additional inspection fees are not furnished to the town within said thirty-day period, the owner/developer must cease any and all construction of site improvements until the additional inspection fees are paid. The project inspection escrow fund shall be held in an interest bearing account, and any balance of the account, including interest, shall be returned to the owner/developer after completion and dedication of the improvements.
A.
Prior to acceptance by the town of the dedication of the street as guaranteed by § A251-4A(2) above, the developer shall deposit with the Town Clerk a letter of credit or a maintenance 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 that, for a period of one year from the date of acceptance of the dedication of the street by the town, the developer will maintain that 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.
B.
The amount of the maintenance bond shall be at least
equal to 10% of the original amount of the performance bond.
C.
Subsequent to the acceptance of the dedication of
the street and after receipt of the maintenance bond, the Town Board
may release all or part of the performance bond.
A.
The Town Planning Board shall determine and designate
into which of the four 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 specification
for its designated classification, as also hereinafter set forth,
as well as in accordance with the specifications and details common
to all classifications.
C.
Fire lanes or fire apparatus access roads shall be
constructed generally equivalent to the standards established for
rural roads.
A.
A proposed street shall be designated a major or through
street when any of the following conditions exist as determined by
the Town Planning Board at the recommendation of the Town Engineer
and/or the Commissioner of Public Works:
(1)
The proposed street is the direct and logical continuation
of a street that carries 500 or more cars during a twelve-hour period
as shown by the latest traffic count.
(2)
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 within two years
after opening.
(3)
The proposed street is the principal collector for
300 or more homes in the neighborhood.
(4)
The proposed street could logically be expected to
become a major street because of future construction or other foreseeable
circumstances.
B.
A proposed street shall be designated a commercial
or industrial street when any of the following conditions exist:
(1)
The proposed street is in an area zoned for commerce
or industry.
(2)
The proposed street 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 a substantial volume of commercial
or industrial traffic.
(3)
The proposed street creates a shorter and more convenient
route between a commercial or industrial area and a major traffic
artery.
(4)
The proposed street for any other reason may be expected
to carry a substantial volume of commercial or industrial traffic.
C.
A proposed street shall be designated a suburban-type
street (NOTE: This classification is intended to cover the majority
of subdivision streets) when any of the following conditions exist:
D.
A proposed street shall be designated a rural-type
street when any of the following conditions shall exist:
(2)
The proposed street is not or cannot reasonably be
expected to become a continuation or extension of a street of one
of the three 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.
(3)
The proposed street does not or cannot reasonably
be expected to carry a substantial volume of traffic.
Figures 1, 2, 3, 4 and 5[1] show cross sections of each of the four classifications
of subdivision streets. These give the required design, dimensions
and construction details which are applicable to a particular classification.
Following is a comparative summary sheet which lists the major items
of construction for all types of streets and may be useful as a checklist
of requirements. Thereafter are set forth the general and more detailed
specifications for design and construction applicable to all streets.
The developer shall design and construct streets which shall conform
to both the specific and the general specifications.
[1]
Editor's Note: Copies of Figures 1 through
17 are at the end of this chapter.
A.
Prior to the start of construction within the proposed
right-of-way, the owner/developer shall contact the Commissioner of
Public Works to arrange a preconstruction meeting. Attendees at this
meeting should include the owner/developer, the Commissioner of Public
Works, the owner's/developer's general contractor or construction
supervisor, and the town's designated inspector. The primary purpose
of the meeting will be to establish communication and inspection procedures
to allow for an orderly and code compliant progression of the work.
B.
Layout. 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 Commissioner
of Public Works and/or the Town Engineer.
C.
D.
Excavation, filling and rough grading.
(1)
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 plans and as otherwise may be directed
by the Commissioner of Public Works. All unsuitable or unstable materials
shall be completely excavated and removed from the right-of-way, and
all rock or boulders larger than six inches in diameter shall be excavated
at least eight inches below the finished structures, curbs and sidewalks.
(2)
Where fills are necessary to complete the required
line and grade or to backfill other excavations, the materials incorporated
into the work shall be acceptable to the Commissioner of Public Works
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-tired or padded-wheel roller, or by impact rammer
or vibratory equipment in areas inaccessible to power rollers. All
compaction shall continue until the fills are firm and unyielding.
(3)
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.
(4)
Earth shoulders and the 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.
A.
Design. The storm drainage system shall be designed
in accordance with the criteria established by the Town of Wallkill
in these specifications. The minimum grade of any drainage pipe shall
be 1%. Any deviations from the criteria herein shall be specifically
noted and approved by the town during the Planning Board review and
approval process.
B.
Excavation, laying and backfilling.
(1)
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 and shall not exceed the pipe's outside
diameter plus 24 inches when measured at the top of 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 a crushed stone bedding of 3/4 inch having
a thickness under the pipe of not less than eight inches. In all other
areas, the pipe shall be placed on a crushed stone bedding of 3/4
inch having a thickness of not less than six inches. 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 pipe subgrade 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 up to the pipe subgrade elevation
with 3/4 inch clean crushed stone or other acceptable material. In
all cases, the crushed stone pipe bed of 3/4 inch shall be thoroughly
compacted and shall provide a firm foundation for the pipe.
[Amended 5-26-2016 by L.L. No. 11-2016]
(2)
Pipe shall be laid to true line and grade on the prepared
bed of the trench. All joints in making field connections of reinforced
concrete pipe shall be filled with Portland cement mortar.
[Amended 8-26-2021 by L.L. No. 6-2021]
(3)
Immediately after pipes have been laid, backfilling
shall commence. The material surrounding the pipe, the pipe embedment
zone, shall be crushed stone of 3/4 inch, carefully placed and thoroughly
compacted in such a manner that the line and grade of the pipe are
not disturbed. Backfill material shall be placed evenly and carefully
on both sides and over the pipe in six-inch lifts, and each lift shall
be thoroughly compacted until one foot of crushed stone cover exists
over the pipe.
(4)
Where the drainage pipe is installed outside the paved
limits of right-of-way, the trench above the pipe embedment zone may
be backfilled with material excavated from the trench, if approved
by the Commissioner of Public Works. This backfill shall contain no
stones larger than eight inches in any dimension. The backfill shall
be placed in eight-inch lifts and thoroughly compacted. This backfill
will be carried to an elevation 12 inches below finished grade. Eleven
inches of NYSDOT Item 4 shall then be placed on top of the trench,
covered by one inch of clean topsoil and seed.
[Amended 5-26-2016 by L.L. No. 11-2016]
(5)
Where the pipe is installed in any paved area subject
to vehicular traffic, the entire trench above the embedment zone shall
be backfilled to grade with NYSDOT Item 4, placed in eight-inch lifts
and thoroughly compacted.
(a)
Where NYSDOT Item 4 is referred to in these
specifications and is proposed below pavement or other hard surfaces,
the material shall be compacted to 95% modified proctor.
(b)
The item 4 material shall strictly comply with
Section 304 of the New York State Standard Specifications (Date of

[Added 5-26-2016 by L.L. No. 11-2016; amended 8-26-2021 by L.L. No. 6-2021]
A.
Before fine grading or the construction of curbs and
sidewalks is started, all storm and sanitary sewers and all other
utilities, including house connections and hydrants, gas, electric,
telephone and television cable, shall have been installed and satisfactorily
tested, and all fill and backfill shall have been thoroughly compacted
to the satisfaction of the Commissioner of Public Works.
B.
After completion of the rough grade and prior to the
laying of the geotextile and 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, and this process shall be continued
until no depressions develop. The subgrade shall not be muddy or otherwise
unsatisfactory when the foundation course is laid upon it, and any
questionable areas may be subject to density testing.
C.
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/or geotextile. Once firm and stable, the area shall be
regraded and compacted as above.

A.
After the fine grade and all curbs have been constructed
to the satisfaction of the Commissioner of Public Works, the owner/developer
shall arrange for the sub-grade to be proofrolled with a loaded tri-axle
dump truck in the presence of the Town's construction observer. Any
yielding or unstable areas shall be stabilized, re-proof rolled, and
found to be non-yielding prior to placement of geotextile filter fabric
and foundation course. The developer shall furnish and place a foundation
course of approved NYSDOT item 4 to the depths as called for in these
specifications. In order that the foundation course does not become
contaminated with fine subgrade soil particles over time, a geotextile
filter fabric shall be installed over the fine graded subgrade just
prior to placement of the foundation course materials.
[Amended 5-26-2016 by L.L. No. 11-2016]

to fine. Only materials conforming with the current NYSDOT Specification
Section 304 — Subbase Course shall be utilized for
construction of the foundation course.
C.
The materials shall be placed on the finished subgrade
and geotextile by means of mechanical spreaders, taking sufficient
care not to damage the geotextile, and shall be thoroughly compacted
by rolling with a self-propelled ten-ton roller. 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. Just prior to paving,
the owner/developer shall arrange for the foundation course to be
proofrolled with a loaded tri- axle dump truck in the presence of
the Town's inspector and any soft or unstable areas shall be stabilized
before paving.
[Amended 5-26-2016 by L.L. No. 11-2016]
A.
After the foundation course has been constructed to
the satisfaction of the Commissioner of Public Works, the developer
shall furnish and place a base and/or binder course of plant-mixed
asphalt concrete conforming to the current Standard Specifications
of the NYSDOT, Section 400 Hot Mix Asphalt, for Hot Mix Asphalt (HMA),
37.5mm Base Course and/or Hot Mix Asphalt (HMA), 25mm Binder Course,
as shown in Figures 1, 2, 3, 4 and 5 of these specifications. The
base and/or binder courses shall be installed in accordance with the
requirements of the Standard Specifications of the NYSDOT, to the
compacted thicknesses as shown in Figures 1, 2, 3, 4 and 5 of these
specifications.
[Amended 8-26-2021 by L.L. No. 6-2021]
B.
Should the owner/developer wish to substitute cold
mix asphalt for use as the base and/or binder courses, the materials
and methods shall be submitted and approved in writing by the Commissioner
of Public Works prior to installation.
A.
After the base and/or binder courses have been completed
to the satisfaction of the Commissioner of Public Works, a bituminous
concrete wearing course shall be constructed.
B.
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 placement of additional materials
on that strip.

A.
The developer shall furnish and install a four-way
street name sign at every street intersection made by the streets
he constructs. Signs and posts shall conform to the standards established
by the Commissioner of Public Works.
B.
The developer shall submit proposed street names to
the Commissioner of Public Works for approval.

A.
Monuments shall be set on all right-of-way lines of
streets and at all street intersections, angle points, points of curvature
and subdivision corners. 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.
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.
C.
A licensed land surveyor retained by the owner/developer
shall certify that the location of all monuments is accurate and provide
an as-built right-of-way map and a metes and bounds description of
the as-built right-of-way to the Commissioner of Public Works before
the acceptance of dedication of the street by the Town Board.
D.
Monuments shall be solid concrete, 36 inches long,
four inches square at the top, tapering to five inches square at the
bottom. A No. 3 zinc-coated rebar shall be embedded in the concrete.
The rebar shall protrude 1/2 inch to 3/4 inch from the top of the
concrete. Monuments with the embedded rebar and a two-inch square
brass plate set in the top shall be considered equal.
E.
Monuments of aluminum pipe may be provided if approved
by the Commissioner of Public Works. Aluminum monuments shall be constructed
of thirty-six-inch-long, two-and-three-eighths-inch aluminum pipe,
with a three-and-one-fourth-inch diameter aluminum magnetic cap riveted
to the top.
Where surface water must be lead through other
than right-of-way gutters and storm drains or existing stream channels,
drainage easements having a minimum width of 30 feet and a temporary
width of 50 feet for working access shall be provided in the approved
plans. A greater width shall be provided where called for by other
provisions of these specifications or where necessary to conduct future
maintenance.
A.
With the approval of the Commissioner of Public Works
and 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 14[1] of these specifications, but in no case shall the grade
of an open ditch exceed 10%. Riprap, when called for, shall consist
of field stone or rough, unhewn quarry stones as nearly cubical in
form as is practicable. A weed barrier fabric shall be placed under
the riprap, and then the stones shall be placed upon a cross-section
slope not steeper than 1V to 2H and so laid that the weight of the
large stones is carried by the soil and not by the stone adjacent.
All stones shall be sized as necessary to ensure their permanent stability.
[1]
Editor's Note: Copies of Figures 1 through
17 are 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.
D.
Whenever a drainage pipe enters an open ditch, the
bottom and sides of the ditch shall be riprapped for a distance of
at least 15 feet beyond the end of the pipe.
A.
Roof and cellar drains shall in no case be allowed
to flow into the street right-of-way. These drains shall be daylighted
well back from the street so that water flows from them do not enter
upon the public right-of-way.
B.
With the approval of the Commissioner of Public Works
or the Town Engineer, in writing, these drains may be piped directly
to an adjacent catch basin. Such drains must be installed prior to
the start of fine grading of the streets, and any such piping within
the right-of-way shall be permanently maintained by the owner of the
property serviced by the piping installed.
Wherever 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 and shall be constructed as shown on Figures
16 and 17.[1] The temporary type of construction shall be used only
under special conditions 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.
[1]
Editor's Note: Copies of Figures 1 through
17 are at the end of this chapter.
Streets shall be so designed that finished 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 New York State standards for speeds of 30 miles per hour unless
the street is to be posted for a speed limit in excess of the current
town-wide limit.
The final decision as to the interpretation
of any part of these street specifications shall rest with the Commissioner
of Public Works. 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.
