[HISTORY: Adopted by the Town Board of the
Town of Cornwall 2-12-1990 by L.L. No. 3-1990. Amendments noted where
applicable.]
A.
The Town Board of the Town of Cornwall has determined
that the existing street specifications are outdated in light of the
current accepted construction standards and the need to provide better
roads for the Cornwall community. To that end, the Town Board has
caused this local law to be prepared in an effort to upgrade the requirements
for the construction of roads within the Town of Cornwall. The local
law recognizes the need for greater engineering involvement in the
design and construction of roads, the need for flexibility in performance
and maintenance security and the importance of clear and updated cross
section details, catch basin details and sidewalk and curb details.
B.
In furtherance of the proposed local law, the Town Board does hereby repeal existing Chapter A161 of the Code entitled "Street Specifications for Town Roads"[1] and does hereby designate the Chapter A161 as set forth in this local law to be known as "Road Specifications for Town Roads."
[1]
Editor's Note: Said existing chapter was adopted
8-12-1974 and amended 9-25-1989 by L.L. No. 4-1989.
A.
It is the purpose of these specifications to establish
minimum acceptable standards for roads and road construction within
the Town of Cornwall to conform to legal requirements in the State
of New York, which requirements and standards must be met and paid
for by the offeror proposing that the Town take over such road as
a Town road. Herein, wherever reference is made to the term "offeror,"
the same shall be understood to mean the person, persons, developer,
firm or other entity 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, sidewalks
and monuments.
B.
Dedication of the right-of-way will not be accepted
until the offeror's professional engineer and/or licensed land surveyor
shall have certified to the Town Board, in writing, that the construction
of the road has been completed in accordance with the approved plans
and specifications that follow and that the total right-of-way area
has been cleared of all debris and all construction has been completed
in a workmanlike manner; and the Town Superintendent for Public Works
and the Town Engineer shall have reviewed the completed work and recommended
acceptance of such dedication. When new road rights-of-way are offered
to the Town for dedication, four copies of the final as-built plan
and deed description of the right-of-way shall be submitted to the
Town Superintendent of Public Works for approval.
C.
In his written certification as required above, the
offeror's professional engineer or qualified licensed land surveyor
shall state clearly that he or his authorized representative has inspected
all phases of the road construction and that all work has been completed
in accordance with the approved plans and these specifications.
A.
A plan of the proposed road shall be prepared by a
qualified professional engineer and/or qualified land surveyor, licensed
by the State of New York for such design functions. The plan shall
clearly define the limits of the proposed right-of-way by metes and
bounds and shall include the location, widths, profiles and grades
of the proposed roadway, storm drainage, including culverts, and other
drainage structures and the location of all easements and utilities.
B.
The plan shall also indicate the owner of the property
and the name of the developer, if other than the owner. One copy each
of the plan shall be submitted to the Town Superintendent of Public
Works and the Town Engineer at the time of application to make such
road a Town road and to the County Commissioner of Public Works or
his designated representative when said proposed street drains toward,
intersects with or may otherwise affect a county highway. If applicable,
it will concurrently be submitted to the Town Planning Board 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 road must be conveyed to the Town by a deed in recordable
form acceptable to the Town Attorney, containing a metes and bounds
description, together with recording fees payable to the Orange County
Clerk accompanied by such evidence of title indicating that title
is vested in the Town free and clear of any liens and encumbrances,
including, where required, a policy of title insurance.
C.
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 width of 20 feet of easement shall be required for the maintenance
of said easements.
D.
The proposed roadway must be constructed to conform
to the minimum requirements and standards set forth below. The minimum
width to be cleared shall include all trees, rock formations, buildings,
walls and any such things that would endanger those using such roadway.
The removal of such obstructions shall be borne by the offeror proposing
such road.
E.
In general, all materials and methods of construction
required for construction of Town roads shall be in accordance with
the Standard Specifications, Construction and Materials, published
by the New York State Department of Transportation (NYSDOT), Design
and Construction Division, latest revision.
This local law repeals existing Chapter A161 of the Code of the Town of Cornwall.
Plans submitted shall not be altered or amended
after having been approved by the Town Superintendent of Public Works
and the Town Engineer unless amended plans are resubmitted and approved.
However, the offeror, at his own expense, shall provide additional
storm drainage facilities, utilities and/or other miscellaneous work
as may be ordered by the Town Superintendent of Public Works and the
Town Engineer if, during the course of construction, in the opinion
of the Town Superintendent of Public Works, the Town Engineer and/or
the County Commissioner of Public Works, such additional structures
or facilities are necessary to prevent any need for future installations
of utilities or culverts within the pavement area and to assure the
durability of pavement, future maintenance of the right-of-way or
welfare and safety of the public.
A.
Performance security. Unless the offeror shall construct
the entire road and related improvements in accordance with this local
law before offering the same to the Town, prior to the start of construction
of any road or at the time designated in the subdivision regulations,
if applicable,[1] the offeror shall post performance security with the Town
either in the form of a bond of an acceptable surety, an irrevocable
letter of credit, negotiable government bonds, cash or bank or certified
funds drawn on a national or state bank to guarantee construction
of the improvements in compliance with the approved plans and these
specifications. The form of the performance security shall be reviewed
and approved by the Town Attorney. Where such proposed road is subject
to the subdivision regulations of the Town, procedures for posting
the performance security shall also comply with those regulations.
The amount of the performance security shall be based on current municipal
construction costs and shall be reviewed and approved by the Town
Engineer and approved by the Town Board.
B.
Maintenance security. The offeror shall post maintenance security
with the Town in the form of either an irrevocable letter of credit,
cash or bank or certified funds drawn on a national or state bank
to guarantee that for a period of one year from the date of acceptance
of the dedication of the road by the Town Board, the developer will
maintain the road to the standard of construction set by these specifications,
normal wear and tear excepted. This shall mean that the offeror will,
at its 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
offeror or others, outside the right-of-way. During the maintenance
period, the Town shall be responsible for snow and ice control, street
cleaning, cleaning of culverts and catch basins and other work of
similar routine nature, provided that such work has in no way been
caused by the operations of others. The amount of the maintenance
security shall be determined by the Town Engineer and shall be equal
to 10% of the original amount of the performance security. The provisions
of the local law concerning review and acceptance of the form of the
performance security shall be applicable to the form of the maintenance
security.
[Amended 1-9-2017 by L.L.
No. 1-2017]
C.
Inspection fees. Upon the completion of the design
for the Town road and determination of the amount of the performance
security as set forth above, the offeror shall pay to the Town an
inspection fee in the amount of 4% of the performance security. Road
construction shall not commence until the four-percent inspection
fee has been paid. The inspection fee must be paid whether or not
the offeror elects to construct the road without the posting of performance
security; in that event, the inspection fee shall be placed upon 4%
of what the performance security would have been had the offeror availed
itself of the option of posting performance security.
A.
Subdivision roads.
(1)
For roads in subdivisions, the Town Superintendent
of Public Works and the Town Engineer shall, pursuant to a recommendation
by the Town Planning Board, determine and designate into which of

C.
Alternate minor road.
(1)
Where approved by resolution of the Town Board, subsequent
to the recommendations of the Town Planning Board, the Superintendent
of Public Works and the Town Engineer, construction of a Town road
without curbs, in accordance with the Alternate Minor Street Detail
(Figure 4), will be permitted. Where required by the Town Board, such
alternate minor road shall be provided with concrete sidewalks.
(2)
Requests for construction of alternate minor roads
shall be made in writing to the Town Board.
A.
The offeror shall establish and clearly mark on site
the limits of road rights-of-way and easements with permanent monuments
on the center line and grades of the finished road pavement and the
location and elevations of drainage structures as shown on the approved
plans with construction stakes. Such construction stakes shall be
maintained at the offeror's expense until the construction of road
pavement, drainage structures, underground utilities, curbs, sidewalks
and shoulders has been completed, inspected and approved by the Town
Superintendent of Public Works and the Town Engineer.
B.
During the course of construction, the developer shall
provide the Town Engineer with stakeout information, cut sheets or
any other pertinent information requested with respect to the proposed
construction.
C.
Permanent monuments shall be set on right-of-way lines
of roads at all intersections, angle points, point of curvature and
the beginnings and ends of streets. There shall be a clear view of
adjacent monuments on the right-of-way line. All monuments shall exist
on completion of the construction of the roads.
D.
The permanent markers shall be made of concrete or
granite with minimum dimensions of 30 inches long, a four-inch square
top and a six-inch square bottom with a one-half-inch drilled hole
in the top. As an alternate, 3/4 inches in diameter steel rods, with
a welded copper coating and bronze tops, 30 inches long, may be used
as monuments. If a monument should be located in a rock ledge, the
surface shall be stripped and a one-half-inch steel rod drilled into
the ledge to a depth of six inches. Monuments shall protrude a maximum
of two inches above the final graded surface. The offeror's licensed
surveyor shall certify that the location of all monuments is accurate
before acceptance of the road by the Town Board. A certified reproducible
map showing the locations and reference ties to each monument shall
be provided. Reference ties shall be permanent items, such as building
foundations, and a minimum of three shall be provided for each monument.
Where surface water from roads must lead through
other than gutters and storm drains or existing stream channels outside
the right-of-way, permanent drainage easements having a minimum width
of 20 feet shall be provided to a point where a natural watercourse
exists. In some cases this may include easements over property outside
the boundaries of the subdivision involved. Natural stream or ditch
channels shall have a minimum of twenty-foot-wide permanent easements
and be shown on the proposed plans of the subdivision. All permanent
easement lines shall be monumented as a right-of-way.
A.
The offeror shall clear and grub the entire area within
the limits of the road right-of-way, drainage channels and easement
areas where required by the Town Superintendent of Public Works and
the Town Engineer. The offeror shall properly dispose of all waste
materials (stumps, roots, etc.) off site.
B.
The offeror 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 required
by the Town Superintendent of Public Works 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 under roadways shall be made with foundation course
material meeting or exceeding the requirements of Gradation Type No.
3 subbase material as specified under Section 3 of the New York State
Department of Transportation Standard Specifications-Construction
and Materials (latest revision), or other acceptable material as approved
by the Town Superintendent of Public Works and the Town Engineer.
Such fills shall be made in layers of not more than 12 inches each
and properly compacted with a ten-ton roller or equivalent.
C.
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 spot or unstable portion of the subgrade
which develops 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.
D.
If, in the opinion of the Town Superintendent of Public Works and the Town Engineer, it is prudent that stabilization fabrics be installed under the Town road in those areas observed as unstable or soft or in other areas deemed appropriate by the Superintendent and the Engineer, the offeror, at his own expense, shall provide such fabric for those areas and for the length of roadway as determined by the Town Superintendent of Public Works and the Town Engineer. Stabilization fabric shall meet the requirements as called for under § A161-17 of these specifications.
E.
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 Public Works and the Town
Engineer before the foundation course is laid. No large stones or
rock ledges shall protrude into the foundation course.
F.
Should it become necessary, as part of the construction
work, to perform blasting, the same shall only be done following notification
to the Town Superintendent of Public Works and the Town Engineer.
The Town shall assume no responsibility or liability pertaining to
any blasting work. Prior to any blasting, the contractor shall submit
an insurance certificate for the type work, in an amount no less than
$1,000,000, for the work to be performed. All work shall be done taking
all possible precautions and shall, at minimum, comply with all applicable
federal, state and local regulations. Blasts shall be covered with
suitable mats or heavy timber, at minimum, to prevent damage. Blasting
shall only be performed between 8:00 a.m. and 5:00 p.m. on weekdays
unless otherwise approved. Blasting shall not be performed on legal
holidays.
G.
Also, before the foundation course is laid, all storm
and sanitary sewers and all utilities, including house connections
for existing and future homes, and hydrants shall have been installed
to the satisfaction of the Town Superintendent of Public Works, the
Town Engineer and the Water Superintendent. All slopes and sidewalk
areas shall be graded before the foundation course is made, and all
loose and exposed stones will be removed. 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.

[1]
Editor's Note: The figures are included as
an attachment to this chapter.
(2)
Materials.
(a)
All granular material acceptable for this item
shall be of sound, hard, durable stone, gravel or blast furnace slag,
well graded from coarse to fine, and shall meet the approval of the
Town Superintendent of Public Works and the Town Engineer. The particles
shall not exceed such size as will pass through a two-inch square
hole; 30% to 65%, by weight, shall pass the one-fourth-inch square
sieve; 5% to 40%, by weight, shall pass the No. 40 mesh sieve; and
not more than 10%, by weight, shall pass the No. 200 mesh sieve, as
determined by washing through the sieve in accordance with ASTM Designation
D422 (latest revision). The particles passing the No. 40 mesh sieve
shall have a maximum Plasticity Index of 5. Of the particles retained
on the one-half-inch square sieve, not more than 30%, by weight, shall
consist of flat or elongated pieces. A "flat or elongated piece" is
defined herein as one the greatest dimension of which is more than
three times the least dimension.
(b)
The quality of the gravel, stone or slag particles
shall be determined by the magnesium sulphate soundness test. The
maximum percent loss at four cycles, by weight, shall be 20.
(c)
The source of the material shall be stripped
of all sod, topsoil, overburden and other objectionable material before
the excavation operations for the material are started and shall be
kept stripped at a minimum of 30 feet from the top of the working
face of the source at all times.
(d)
The material shall be stockpiled on site or
otherwise be made available for inspection by the Town Superintendent
of Public Works and/or the Town Engineer prior to placement. Prior
to material being delivered to the site, the developer/offeror shall
furnish the Town with certified laboratory test results for the material
to be utilized.
(e)
Should, at any time during work and for any
reason, in the opinion of the Town Superintendent of Public Works
or the Town Engineer, the material fail to conform to the specified
quality and gradation requirements, the offeror shall, by the addition
of selected acceptable material and/or satisfactory manipulation,
produce a material meeting the above requirements, and he shall retest
the material to demonstrate compliance to the satisfaction of the
Town Superintendent of Public Works and the Town Engineer.
(f)
It is the intent of this specification to provide
a foundation course material meeting or exceeding the requirements
of Gradation Type No. 4 subbase material, as specified under Section
304 of the New York State Department of Transportation Standard Specifications
- Construction and Materials (latest revision).
(3)
Construction details.
(a)
After excavation from the source and processing
and blending, if necessary, the material shall be stockpiled. Stockpiles
shall be located at a distance of not less than 50 feet from the outside
bottom edge of the conical stockpile built up under the processing
plant conveyor or not less than 50 feet from the toe of the working
face of the source. Unless otherwise approved, in writing, these stockpiles
shall be formed in layers having a maximum thickness of two feet and
to a height not exceeding 12 feet and shall contain not less than
1,000 cubic yards or the amount needed for the job, whichever is smaller.
Removal of material from stockpiles for placement on the grade shall
be by side excavation along nearly vertical faces for the full depth
of the stockpile. The use of a clamshell-type bucket for loading the
removal trucks or the use of pan-type scrapers for moving the stockpile
material to its final position as subbase course will not be permitted.
(b)
No material shall be added to a stockpile after
the stockpile has been sampled for approval. Only material from approved
stockpiles shall be placed on the grade for this item. The presence
of any oversize particles in the stockpile will be cause for rejection
of the entire stockpile.
(c)
No material shall be removed for use from any
stockpile until the stockpile has been sampled, tested and approved
by the Town Superintendent of Public Works and the Town Engineer for
placement on the grade. Approval of a stockpile for placement on the
grade shall not relieve, in any degree, the full responsibility of
the offeror to furnish, in its compacted position, a subbase course
of select granular materials, the final condition of which conforms
to all requirements of the specifications for this item.
(d)
The spreading of any layer of this material
shall be done with spreader equipment acceptable to the Town Superintendent
of Public Works and shall be spread to such thickness that the maximum
depth of the layer, after compaction, will be six inches. Spreading
from piles dumped on the roadway will not be permitted. No segregation
of large or fine particles will be allowed, but the material, as spread,
shall be well graded, with no pockets of fine material. Water shall
only be added and in such amounts as acceptable to the Town Superintendent
of Public Works and the Town Engineer and only as necessary to obtain
satisfactory compaction.
(e)
When the moisture content of the layer is within
the limits for proper compaction, the entire surface shall be rolled
with a pneumatic-tired roller having an operating weight of between
1,000 and 2,500 pounds per tire or a smooth-steel-wheel roller having
a minimum weight of 10 tons. Each portion of the layer shall be covered
by a minimum of eight passes of the roller.
(f)
For heavier, vibratory or more efficient types
of approved compaction equipment, the minimum number of passes required
on all portions of each layer shall be acceptable to the Town Superintendent
of Public Works. In limited areas, where the use of a roller is impractical,
approved vibrating plate compactors or impact rammers shall be used
to compact the material.
(g)
After compaction, the top surface of this course
shall not extend above nor more than 1/2 inch below true grade and
surface at any location. The foundation course, at any location, shall
be compacted, finished and completed to the above tolerance and approved
by the Town Superintendent of Public Works before any succeeding course
is placed at that location. Any depressions or holes shall be filled
with approved coarse sand or screenings conforming to specifications
and the surface rerolled.
(h)
In all cases, this subbase course must be so
thoroughly compacted that it will not weave under the roller.
(i)
The width of the layer of this subbase course
shall be restricted to that required for placement of the lane being
paved and shall not be laid in excess of 500 linear feet without being
compacted. No traffic or hauling other than that necessary for bringing
material for the next course shall be permitted over this course.
Should the subgrade or any other material become churned up into or
mixed with this foundation course through any reason whatsoever, the
offeror shall, at his own expense, remove such mixtures and repave
with select granular material acceptable for this item.
B.
The offeror shall assume full responsibility for any
contamination and/or degradation of any part of this course during
construction and shall, at his own expense, remove any and all portions
of this course which do not conform to the requirements of these specifications
and replace these portions with specified material.
Pavement; base course. After the foundation
course has been inspected and accepted by the Town Superintendent
of Public Works and the Town Engineer, with the three-month minimum
settlement period elapsed, and found to be at a grade allowing the
proper depth of finished pavement, one of the following two base courses
shall be laid (selection in accordance with road classification):

No mailbox or newspaper delivery box, hereafter referred
to as "mailbox," will be allowed to exist within a Town right-of-way

[Amended 1-9-2017 by L.L.
No. 1-2017]
No owner or occupant or other person shall place,
keep, permit or suffer to be placed or kept on any sidewalk in front
of, adjoining or adjacent to such premises any goods, wares, merchandise,
boxes, barrels, display signs or material things of any kind or description
nor shall he in any manner obstruct any such sidewalk or in any manner
obstruct or interfere with the use of any such sidewalk. Nothing contained
in this local law shall prevent such persons from placing foods, wares
or merchandise on the sidewalk temporarily while loading or unloading
the same, provided that it be done without unnecessary delay and provided
that such goods, wares or merchandise are not allowed or permitted
to remain on such sidewalks within the prohibited area for a period
longer than one hour.
Final decision as to the interpretation of any
part of these road specifications shall rest with the Town Superintendent
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, when conditions
make it unnecessary to do so and when it is in the best interest of
the Town of Cornwall.
