[Adopted 2-9-2004 by L.L. No. 5-2003[1]]
A.
The Town Board of the Town of Marlborough 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that the existing street specifications are outdated in light of the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 Marlborough community. To that end, the Town Board has
caused this article to be prepared in an effort to upgrade the requirements
for the construction of roads within the Town of Marlborough. This
article 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 sections details, catch basin details and sidewalk and
curb details.
A.
It is the purpose of these specifications to establish
minimum acceptable standards for roads and road construction within
the Town of Marlborough 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 Highway Superintendent and the
Town Engineer shall have reviewed the completed work and recommended
acceptance of such dedication in writing to the Town Board. 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 Highway Superintendent 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 Highway Superintendent
and the Town Engineer at the time of application to make such road
a Town road and 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[1] of the Town. Such roadway must not be subject to any right
or easement to 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 Ulster 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 a policy of title insurance in favor of the Town.
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
Standard Specifications, Construction and Materials, published by
the New York State Department of Transportation (NYSDOT), Design and
Construction Division, latest revision.
A.
Plans submitted shall not be altered or amended after
having been approved by the Town Highway Superintendent and 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 Highway Superintendent and/or Town Engineer if, during the course
of construction, in the opinion of the Town Highway Superintendent,
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.
B.
Plans approved by the Planning Board shall not be
altered without resubmittal and approval of the Planning Board.
[Amended 9-14-2009 by L.L. No. 6-2009]
A.
Performance security. Unless the offeror shall construct
the entire road and related improvements in accordance with this article
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,[1] if applicable, 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 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 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 result of faulty construction
within the right-of-way or as a result of other construction, by the
offeror or others. 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 this article concerning
review and acceptance of the form of the performance security shall
be applicable to the form of the maintenance security.
A.

NOTE: The subbase and foundation course shall
lay a minimum of three months to allow complete settlement before
pavement is laid.
|
A.
The offeror shall establish and clearly mark the limits
of road rights-of-way and easements with permanent monuments. Temporary
center lines, grades of the finished road pavement, and the location
and elevations of drainage structures as shown on the approved plans
shall be delineated 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 Highway Superintendent 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, points 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 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

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.

(3)
Where a proposed road 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 offeror under the review of the Town Highway Superintendent,
the Town Engineer and the County Commissioner of Public Works or his
representative, as applicable. The County Commissioner of Public Works
shall be notified of all intersections with county roads for approval
of location, grade and drainage structures prior to any construction
of the proposed street.
At their discretion, the Planning Board may
require that paved gutters be constructed the entire length of the
proposed street on both sides. Such paved gutters shall be considered
as part of the construction of shoulders after the street pavement
has been laid. Grading of shoulders and paved gutters shall be simultaneous,
being shaped and rolled just prior to the application of the bituminous
concrete (asphalt) for shoulders and paved gutters. The grades on
paved gutters shall be maintained relative to the center line elevation
to ensure positive runoff of surface water. It would be noted that
the foundation course of the street pavement extends to the outer
edge of the paved gutters.
All materials used as part of the road structure
are subject to the approval of the Town Highway Superintendent and

[1]
Editor's Note: Said figures are included at
the end of 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 Highway Superintendent 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%, the No. 200 mesh 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 dimensions.
(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 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 Highway Superintendent
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 Highway Superintendent 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 Highway Superintendent
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. Stockpile
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
plan 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 refection
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 Highway Superintendent 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 Highway
Superintendent 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 Highway
Superintendent and 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 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 Highway
Superintendent. 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 Highway Superintendent before any succeeding course is
placed at that location. Any depressions or holes shall be filled
with approved material conforming to specification 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
this course which do not conform to the requirements of these specifications
and replace these portions with specified material.
After the foundation course has been inspected,
proof rolled, and accepted by the Town Highway Superintendent and
the Town Engineer, and found to be at a grade allowing the proper
depth of finished pavement, the following shall be laid:
A.
Hot-mix asphalt concrete pavement.

(2)
Placement.
(a)
Bituminous material shall not be applied on
a wet surface, when the air temperature is below 50° F. or greater
than 95° F., unless otherwise permitted, or when weather conditions
would prevent the proper construction of the surface treatment. The
following equipment shall be required:
(b)
The bituminous material distributor shall be
so designed, equipped, maintained and operated that the bituminous
material at even heat can be applied uniformly on variable widths
of surface up to 15 feet at readily determined and controlled rates
from 0.05 to 2.0 gallons per square yard, with uniform pressure, and
with an allowable variation from any specified rate not to exceed
0.02 gallon per square yard. Distributor equipment shall include a
tachometer, accurate volume measuring devices or a calibrated tank
and a thermometer for measuring temperatures of tank contents. Distributors
shall be equipped with a power unit for the pump and full circulation
spray bars adjustable laterally and vertically.
(c)
The distributor and/or transport shall be equipped
with a sampling valve so designed and installed as to be nonclogging
and safe. When samples are taken through such valves, they shall be
considered representative of all material in the tank.
(d)
The pneumatic rubber tire roller shall be self-propelled
and have oscillating wheels with smooth-tread tires. The tire or contact
pressure shall be as acceptable to the Town Highway Superintendent.
The roller shall be operated at a maximum speed of five miles per
hour.
(e)
The bituminous material distributor and aggregate
spreader shall be subject to the acceptance of the Town Highway Superintendent.
(f)
The surface shall be free from irregularities
to provide a reasonably smooth and uniform surface to receive the
treatment. Areas which are stable and firm and require one inch or
less in thickness to patch or shape the surface may be patched with
surface treatment materials. Unstable and/or corrugated areas shall
be removed and replaced. Areas requiring replacing, patching or shaping
in excess of one inch in thickness shall be constructed with materials
acceptable to the Town Highway Superintendent and the Town Engineer.
(g)
A power broom shall be used to clean any loose
material from the pavement surface before the bituminous material
is applied. Manhole covers, drop inlets, catch basins and any other
structures within the roadway area shall be protected against the
application of the surface treatment materials.
(h)
Bituminous material shall be applied by means
of a pressure distributor in a uniform, continuous spread over the
section to be treated and within the temperature range specified.
The quantity of bituminous material to be used shall be 0.5 gallon
per square yard for the first course and 0.4 gallon per square yard
for the second course for the indicated aggregate gradation, unless
otherwise approved. A strip of building paper at least three feet
in width and with a length equal to that of the spray bar of the distributor,
plus one foot, shall be used at the beginning of each spread. If the
cutoff is not positive, the use of paper may be required at the end
of each spread. The paper shall be removed and disposed of in a satisfactory
manner. The distributor shall be moving forward at proper application
speed at the time the spray bar is opened. Any skipped areas or deficiencies
shall be corrected. Junctions of spreads shall be carefully made to
assure a smooth riding surface.
(i)
The length of spread of bituminous material
shall not be in excess of that which trucks loaded with cover coat
material can immediately cover.
(j)
The spread of bituminous material shall not
be more than six inches wider than the width covered by the cover
coat material from the spreading device. Under no circumstances shall
operations proceed in such a manner that bituminous material will
be allowed to chill, set up, dry or otherwise impair retention of
the cover aggregate.
(k)
The distributor, when not spreading, shall be
parked so that the spray bar or mechanism will not drip bituminous
material on the surface of the traveled way.
(l)
Immediately following the application of the
bituminous material, cover aggregate shall be spread in the range
of 15 to 25 pounds per square yard for the indicated aggregate, unless
otherwise approved. Spreading shall be accomplished in such a manner
that the tires of the trucks or aggregate spreader at no time contact
the uncovered and newly applied bituminous material.
(m)
Immediately after the cover aggregate is spread,
any deficient areas shall be covered by additional material. If the
application of the aggregate cover by the spreader is not uniform,
the Town Highway Superintendent may require the contractor to use
a drag broom before rolling. Pneumatic tire rolling shall begin immediately
and shall be continued until three complete coverages are obtained.
(n)
Any free bituminous material on the surface
caused by a deficient amount of cover aggregate shall be covered in
such a manner so as not to displace imbedded material. Excess material
shall be swept from the entire surface by means of brooms. The surface
shall be swept at the time determined by the Town Highway Superintendent.
(o)
Traffic shall be discontinued on the lane being
surface treated, and as soon as the final layer is applied and rolled,
controlled traffic may be permitted thereon. Traffic shall be maintained
at a speed not to exceed 15 miles per hour for two to four hours after
rolling. The time and minimum requirements of traffic control shall
be as acceptable to the Town Highway Superintendent.
(p)
Sufficient time shall elapse between the completion
of the first course and the placing of the surface course so that
the bituminous material in the first course has time to set or cure.

the work shall be stopped and will be resumed only when the desired
results are likely to be obtained or when acceptable corrective measures
and procedures are adopted.
C.
Areas to be seeded shall be maintained at acceptable
grades. Irregularities which will form low places and hold water shall
be eliminated. The offeror shall care for the seeded and mulched areas
until the end of the maintenance bond term. Such care shall consist
of repairing any areas damaged following the seeding or mulching operations
due to wind, water, fire or other causes. Such damaged areas shall
be repaired to reestablish the condition and grade of the area prior
to seeding and shall then be refertilized, reseeded and remulched
as specified herein.

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 they 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 article shall prevent such persons from placing
foods, wares or merchandise on the sidewalk temporarily while loading

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.

and the contractor or person performing the work shall schedule such
work as to permit the necessary reviews and inspections. Where applicable,
a fee shall be paid to the Town for such reviews and inspection.

and recognized guidelines and the specifications for road opening
permit guidelines in effect at the time of the work.

A.
A "private road" shall be defined as a road privately owned and maintained as an access way for between two to four lots, connecting to a public street. No more than four lots may be served by a private road. However, up to two additional lots may use the private road, if a private agreement so allows, provided that those two additional lots have the minimum required frontage under Chapter 155, Schedule I, of the Town Code on a public street or highway. Lots enjoying frontage variances on a public street or highway shall not be eligible to increase the number of lots on a private road. For purposes of the private road use count, no distinction shall be made between developed or undeveloped lots having the right to utilize said private road. However, the private road use count as addressed under this subsection must be considered prior to any building permit being issued for any lot. Excess lots on a private road shall not be eligible for a building permit. No subdivision shall contain more than one private road.
[Amended 8-13-2018 by L.L. No. 4-2018]
B.
The owner of any lot or parcel that abuts an approved
private road shall be the fee owner to the centerline of the private
road along the full width of the lot or parcel. A proposed easement
as necessary to provide for ingress, egress and/or access to and over
a private road for all parcels on the private road shall be submitted
to the Planning Board for review and approval by the Planning Board
attorney prior to granting of final approval for any subdivision or
site plan application containing a private road.
C.
In all cases, dimensions used in determining compliance
with zoning bulk, frontage and setback regulations shall be measured
from or along the right-of-way lines indicated for the private road.
D.
Responsibility for maintenance.
(1)
Where a subdivision plat containing a private
road is approved and filed with the Ulster County Clerk, such subdivision
plat shall contain a note clearly stating that the subdivision contains
a private road which the Town of Marlborough has no responsibility
to maintain, nor provide services for, nor make any improvements to;
that all such costs shall be borne by the property owners approved
to use said road in accordance with the terms of maintenance declaration
or agreement, as referenced herein below.
(2)
All private roads will have provisions for the
maintenance of said private road, pertinent drainage facilities and
other improvements incorporated in a maintenance declaration or agreement
which shall be recorded in the Ulster County Clerk's office at the
time of filing of the subdivision plat and prior to the transfer in
ownership of any subdivision lot. A proposed private road maintenance
agreement shall be submitted to the Planning Board for review and
approval by the Planning Board attorney prior to granting of final
approval for any subdivision application containing a private road.
The private road maintenance agreement shall require the maintenance
of all aspects of the private road, including, but not limited to,
snowplowing, sanding, pavement repairs, maintenance and cleaning of
drainage structures and mowing, and shall provide that such maintenance
shall be the responsibility of the owners of the private road. Such
private road maintenance agreement shall further provide for an annual
safety access inspection for fire and emergency services. Private
road maintenance agreements shall not prohibit future modifications
to allow for extensions or upgrades to the private road. A copy of
the private road maintenance agreement shall be filed with the Town
of Marlborough Building Department and Ulster County Clerk.
(3)
A private road may not be offered for dedication to the Town of Marlborough unless the owners of the private road shall first have caused it to meet the current applicable street specifications in the Town of Marlborough, identified in Article I of this chapter. In the event a private road is dedicated to the Town of Marlborough, the front lot line of all parcels adjacent to such road shall be located at least 25 feet from the centerline of the road.
(4)
There shall be adequate provision for maintenance of private roads
serving multifamily residential developments, including condominium
or townhouse projects, by means of an acceptable homeowners' association
or similar entity.
E.
Private road construction specification. 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
at a minimum conform to the standards set forth below.
(1)
The maximum permitted length of a private road
to serve a proposed subdivision or multifamily residential development,
including a condominium or townhouse project, shall be determined
by the Planning Board upon a finding that such maximum length would
not be detrimental to the public health, safety, welfare and general
convenience.
(2)
The private road will have the subbase prepared
and compacted to the maximum density. Where grade alteration is required,
the same shall be by use of run-of-bank or other no-frost-susceptible
material, compacted to maximum density.
(3)
Said private road will have a base course which
conforms to the requirements for a minor road as set forth in this
chapter.
(4)
The paved portion of a private road shall not
be less than 24 feet in width and shall have, in addition, shoulders
three feet in width on both sides of the road, which shoulders shall
be compacted to maximum density, and shall also have a three-foot-wide
drainage swale adjacent to each shoulder.
(5)
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 80 feet in diameter.
(6)
Dead end private roads shall end in a cul-de-sac;
said cul-de-sac shall have a finished surface being not less than
60 feet in roadway diameter. The maximum length of a private road
which ends in a cul-de-sac shall not exceed 2,000 feet.
(7)
No portion of any private road shall have a
grade exceeding 14% except that all work within the public road rights-of-way
shall conform to the appropriate standards of the agency having jurisdiction
over the same. Where the slope of a private road exceeds 10%, the
Planning Board may set reasonable requirements, including but not
limited to the provision of temporary parking areas, in order to protect
the public health, safety and welfare.
(8)
All side slopes of lands adjacent to the private
road within the private road right-of-way shall not be steeper than
a slope of 2:1. Alternate side slopes using alternate methods of stabilization
and control may be approved by the Planning Board on a case-by-case
basis.
(9)
If a private road is constructed over a place
where water runs regularly or intermittently underneath said road
or will be caused to do so as part of the proposed subdivision, coated
corrugated metal pipe (CMP) culvert or any alternative pipe materials
approved by the Planning Board shall be installed underneath the road
to permit the passage of water under said road. The size of such pipe
shall be as determined to be acceptable by the Town Engineer.
(10)
All private road names shall be approved by
the Town Board. Such road name shall be posted by street sign which
is identical in construction, character and manner of posting as those
currently installed by the Town of Marlborough for public roadways,
except that the sign shall also be equipped with a separate additional
sign of similar construction which identifies the road as a private
road.
F.
Road plan for private roads.
(1)
A plan of the proposed private road shall be included in the
subdivision plat or site plan and 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 private road and any necessary easements
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 utilities.
(2)
Provisions for drainage and stormwater management shall be a
part of the engineering plan for construction of the private road.
No drainage districts shall be formed for the maintenance of such
drainage facilities. In the event one or more retention ponds are
included in such plans, their maintenance and the cost of such maintenance
shall be included in the private road maintenance agreement required
for the private road.
(3)
Plans for private roads approved by the Planning Board shall
not be altered without resubmittal and approval of the Planning Board.
G.
Private road construction completion. 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 be completed
prior to the issuance of any building permit(s) for the approved subdivision
plat or site plan, except as provided below in this subsection. Construction
of the private road shall be completed within 36 months, or three
years, of the date of final approval of the subdivision plat or site
plan. Failure to complete construction within such time will require
a new application and review by the Planning Board. The Planning Board,
at its discretion, at the time of approval, may allow for issuance
of a maximum of one building permit prior to completion of the private
road. The posting of a performance security in lieu of such construction
completion is prohibited.
H.
Inspection, escrow and certification.
(1)
The construction of the private road must be inspected by the
Town Engineer and Superintendent of Highways.
(2)
An initial escrow to cover the costs of such inspection must
be established in the amount of $5,000, which escrow shall not be
allowed to fall below the amount of $1,000 and which shall be replenished
to an amount agreed upon between the applicant and the Town Engineer.
(3)
Upon completion of the private road, the applicant shall provide
a certification to the Town by a professional engineer and/or licensed
land surveyor, in writing, stating that this authorized representative
has inspected all phases of the road construction and that that the
construction of the private road has been completed in accordance
with the approved plans and specifications in a workmanlike manner.[1]

[Amended 2-9-2009 by L.L. No. 2-2009]
A.
Final
decision as to the interpretation of any part of these road specifications
shall rest with the Town Highway Superintendent.
B.
The
Town Board, after consultation with the Highway Superintendent, shall
have the authority to waive or to modify the requirements of these
specifications when, in its opinion, all of the following conditions
are applicable:
(1)
Unique or peculiar conditions make it impracticable to follow the
strict letter of these specifications without causing significant
hardship to the property owner;
(2)
Issuing the waiver or modification will not establish precedent which
tends to encourage efforts to avoid the standards established in this
chapter;
(3)
The waiver or modification is not contrary to interests of public
health, safety and welfare; and
(4)
The Town Board shall balance the interests of the public against
those of the applicant, and the Town Board must find that the detriment
to be suffered by the public, if any, by the granting of the waiver
or modification is not greater than the benefit to the applicant in
granting the waiver or modification.
C.
Where
the requested waiver or modification affects a matter pending before,
formerly before, or foreseeable to come before the Planning Board,
no action shall be taken without providing the Planning Board with
opportunity to comment on not less than 30 days’ written notice.
