[HISTORY: Adopted by the Town Board of the Town of Monroe 9-12-2013 by L.L. No.
2-2013. Amendments noted where applicable.]
A.
The Town Board of the Town of Monroe 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street specifications are outdated in light of the current accepted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
Monroe community. To that end, the Town Board has caused this chapter
to be prepared in an effort to upgrade the requirements for the construction
of and/or modification of both public and private roads within the
Town of Monroe. This chapter recognizes the need for greater engineering
involvement in the design and construction of roads, performance of
work within existing Town roads, the need for flexibility in performance
and maintenance security and the importance of clear and updated cross
section details, catch basin details, sidewalk and curb details, and
other details of public improvement construction.
B.
In furtherance of the proposed chapter, the Town Board does hereby repeal existing Chapter A63 of the Code entitled "Highway Specifications" and does hereby designate the Chapter A63 as set forth in this local law[1] to be known as "Road Specifications for Town roads."
[1]
Editor's Note: "This local law" refers to L.L. No. 2-2013,
adopted 9-12-2013.
A.
It is the purpose of these specifications to establish minimum acceptable
standards for roads and road construction within the Town of Monroe
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 provided
all necessary as-builts and other documentation and certified to the
Town Board, in writing, that the construction of the road and related
work have 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
Engineer for the Town 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, plus electronic copies as
deemed required by the Town, shall be submitted to the Town 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.
D.
These specifications are also intended to establish a standard for
all work to be performed upon existing Town roads or within Town rights-of-way,
easements and rights-of-way. Such work shall also be certified as
to acceptable completion, as applicable. In such cases the terms "developer"
or "contractor" may be substituted for the term "offerer".
E.
These specifications are also intended to establish minimum standards
for other roadways intended for travel by the general public, emergency
vehicles, delivery vehicles and the like, with such roadways intended
to remain private in nature, and not dedicated to the Town. Such roads
will be known as private roads. Private roads are intended to serve
as access to single-family and two-family residential dwellings. Accessways
which serve to provide access to multifamily residential complexes
and commercial developments shall be constructed to standards equivalent
to a Town road (classification as deemed appropriate by Town), but
shall remain privately owned unless otherwise accepted by the Town
Board for dedication.
F.
All proposed Town roads, private roads and other road accessways
intended for public access shall have a road plan submitted for review
to the applicable board or official within the Town of Monroe for
approval before construction.
G.
These specifications are also intended to prohibit or control activities
within the Town, roads and rights-of-way which may be deemed deleterious
to the Town's improvements or future development, or deemed a
potential hazard in the sole opinion of the Town and its designated
representatives.
H.
For projects requiring approval from the Planning Board or other
boards, departments or agencies, these specifications shall be applicable
unless the subdivision or other plans shall have received all necessary
stamps of approval and shall have been filed/recorded at the Office
of the County Clerk.
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. For privately owned
roads, any applicable access rights-of-way, easements or other rights
for ingress and egress shall be suitably shown and supporting documentation
submitted.
B.
The plan shall also indicate the owner of the property and the name
of the developer, if other than the owner. Two copies each of the
plan shall be submitted to Town Highway Superintendent and the Engineer
for the Town 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 or site plan regulations of the Town. 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. If intended for
dedication, 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 (or in the case of privately owned roads, the
HOA or other responsible party) 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.
In general, a minimum width of 20 feet of easement shall be required
for the maintenance of said easements, unless impractical.
D.
The proposed roadway must be constructed to conform to the minimum
requirements and standards set forth below and per applicable details.
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.
Plans submitted shall not be altered or amended after having
been approved by the Town Board, Town Planning Board, Town Highway
Superintendent and/or the Engineer for the Town unless amended plans
are resubmitted and reapproved by the entity or entities that previously
approved the plans, unless the changes are deemed acceptable field
changes by the board or official that previously approved such plans.
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 the Engineer
for the Town if, during the course of construction, in the opinion
of the Town Highway Superintendent, the Engineer for the Town 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 ensure the
durability of pavement, future maintenance of the right-of-way or
welfare and safety of the public.
A.
Performance bond (security). Performance bonds for all proposed Town roads and public improvements, and all other work to be performed within Town rights-of-way shall be provided in conformance with the provisions of Chapter 36 of this Code. Such security shall guarantee construction of all the improvements in compliance with the approved plans and these specifications. The amount of the performance security shall be based on current municipal construction costs as established by the Engineer for the Town. The estimate shall be reviewed and accepted by the Engineer for the Town and approved by the Town Board.
B.
Maintenance bond (security).
(1)
Following completion of all construction of the roadway and related public improvements, the offeror shall post maintenance security with the Town in conformance with Chapter 36 of this Code. Such security shall guarantee that for a period of one year from the date of acceptance of the dedication of the road (and other related improvements) by the Town Board, the developer will maintain the road and improvements 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 Engineer for the Town and shall be equal to 10% of the original estimate amount of the performance security.
(2)
In cases as may be warranted by conditions specific to the project,
the Town Board may require that the offeror post a maintenance security
for a longer period of time as a condition of acceptance of the road
and/or other public improvements. Such option shall be available in
such cases where potential deficiencies or conditions have been identified
which may require further maintenance attention, and the offer has
requested that the Town Board act to accept dedication. Such determination
to accept dedication with an extended maintenance security term shall
be at the sole discretion of the Town Board.
C.
Restoration bond (security). In all cases where work is proposed pursuant to an application to the Planning Board or other authorization from the Town, the developer or offerer shall provide a restoration bond in conformance with Chapter 36 of this Code, for restoration of the disturbed areas to an acceptable and stable condition, as may be defined by the Stormwater Pollution Prevention Plan (SWPPP), with the amount of such bond to be established as called for in Chapter 36 or as may be further identified in an approved SWPPP. Final amount to be subject to Town Board approval.
D.
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 8% of the total performance security estimate. Road construction or any related utility construction shall not commence until the inspection fee has been paid. The inspection fee must be paid whether or not the offeror elects to construct the improvements without the posting of performance security; in that event, the inspection fee shall be placed upon 8% of what the performance security would have been had the offeror availed itself of the option of posting performance security. These inspection fees do not include additional fees for inspections for developer's compliance with New York State stormwater pollution prevention regulations, as also required for the compliance with the Town's MS4 regulations. Such additional fees shall be paid in accordance with Chapter 46 of the Town Code.
A.
Subdivision roads.
(1)
For roads in subdivisions, the Highway Superintendent and the Engineer
for the Town shall, pursuant to a recommendation by the Town Planning
Board, determine and designate into which of the three following classifications
each proposed road falls on the basis of one or more of the criteria
hereinafter set forth. For all other roads, the Town Highway Superintendent
and the Engineer for the Town shall make this determination.
(2)
Final plans shall be drawn to show and the offeror shall construct
each road in accordance with the particular specifications for its
designated classification as hereinafter set forth, as well as in
accordance with the specifications common to all classifications.
(3)
Determining criteria.
(a)
Major road: a road which serves or is designed to be used primarily
as a route for traffic between communities or large areas, and roads
anticipated to carry a substantial volume of heavy vehicle or truck
traffic.
(b)
Secondary road: a road which serves or is designed to carry
traffic from local residential roads to the system of major roads.
(c)
Minor road: a road intended to serve primarily as access to
abutting residential properties.
(d)
Alternate minor road: a minor road proposed to be constructed
without concrete curbs. Approval must be obtained from the Planning
Board upon recommendations from the Town Highway Superintendent and
Engineer for the Town.
(e)
Private road: a road intended to serve single-family and two-family
residences with such road to be maintained in private ownership and
maintained via a road maintenance agreement to be filed in the office
of the County Clerk and Town Clerk's office. The number of lots
on a private road is restricted as noted in this Code.
B.
Construction specifications.
(1)
Figures 1, 2, 3, 3A and 4 annexed to this chapter[1] show the cross sections of each of the classifications
for Town roads and a private road. Figures 5, 6, 7, 8 and 9 annexed
to this chapter[2] show typical details for construction of Town roads. These
give the minimum required design, dimensions and construction details
which are applicable to each classification.
(2)
The general and more detailed specifications follow for design, construction,
materials and other requirements which are applicable to all classifications
of roads.
(3)
The offeror shall design and construct roads which shall conform
to both the general and specific specifications.
A.
The offeror shall establish and clearly mark on site the limits of
road rights-of-way and easements with 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 accepted by the Town Highway Superintendent and the
Engineer for the Town.
B.
During the course of construction, the developer shall make available
to the Highway Superintendent and the Engineer for the Town 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. Monuments shall be set on both sides of
the right-of-way. Monuments shall be set following completion of the
construction of the roads, but prior to any request for dedication.
Prior to setting any monuments, a proposed monument plan shall be
submitted to the Town Highway Superintendent and the Engineer for
the Town for approval, together with a cut on the specific monument
to be set. Any additional monuments required by the Superintendent
or Engineer shall be added to the final plan. No monuments should
be set until the plan and proposed monuments have approved.
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 two-inch by two-inch cross (centerline) cut into the
top. As an alternate, thirty-inch aluminum drive-in piston monuments
may be utilized. Such monuments shall be provided with three-and-one-fourth-inch
custom-stamped aluminum caps. For purposes of standardization, such
monuments shall be Berntsen Model G130 monument with G2 cap, stamped
to Town of Monroe standard. If a monument should be located in a rock
ledge, the surface shall be stripped and the monument set into a drilled
hole into the ledge to a depth of a minimum of six inches. Monuments
shall protrude a maximum of one inch 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. In addition to the paper
and reproducible maps, electronic copies shall be provided in a form
deemed acceptable by the Town Highway Superintendent and the Engineer
for the Town.
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 in the same manner as a Town road right-of-way
(noted above).
Roadway construction within the Town of Monroe shall be performed
in such a manner that appropriate sequences of construction are utilized,
which are intended to promote a quality construction result and provide
for necessary inspections by Town representatives. The general sequence
of construction as noted hereinbelow shall be utilized, although it
shall be the developer's and contractor's responsibility
to schedule additional inspections and employ proper means, methods
and techniques which will guarantee the quality and durability of
the finished product, and shall comply with the other provisions of
this specification. Any variation of this sequence requires the written
prior approval of the Town Highway Superintendent.
A.
Clearing and grading shall only begin following preparation and approval of a Stormwater Pollution Prevention Plan as may be required by state and local laws, in addition to any necessary Planning Board approvals. (Also see Chapter 46.)
B.
All necessary cut and fills are to be accomplished. All fills within
the Town right-of-way shall be subject to proper inspections of Town
representatives and shall utilize required materials. Use of on-site
material is only permitted following testing and written approval
from the Town as the same being equal in quality to the fill materials
specified herein. Developers/offerors shall be required to employ
a testing laboratory to verify proper materials, compaction and placement.
Original copies of all test results prepared by the testing companies
for materials and placement shall be submitted directly to the Town's
designated representatives.
C.
Prior to the construction of either curbs, sidewalks or the subbase
of the road, all utility lines, services and facilities, to the extent
that they will be in the right-of-way, shall be constructed in their
entirety.
D.
Installation of utilities must be observed. Before being backfilled,
as-built ties should be made of all subsurface improvements. Such
ties shall be by a licensed land surveyor under the employ of the
developer/contractor, who shall be such professional who will prepare
as-builts of the improvements. Subsequently, all utilities shall be
tested under the supervision of the design professional. Representatives
of the Town must also observe all testing, and as-builts provided
as soon as practical.
E.
Subsequent to completion of all utilities and the road grading (and
prior to installation of the subbase "item" course), proof-rolling
of the roadway must be performed in the presence of the Town Highway
Superintendent and Engineer for the Town. At the time of proof-rolling,
measurements should be made of the subgrade to verify proper depth
relative to the curb for proper pavement/subbase structure. The Town
representatives should be contacted to observe such measurements.
F.
After acceptance of the proof-rolling, no subsequent excavations
shall be made within the right-of-way area without the express prior
approval of the Highway Superintendent and Engineer for the Town.
Following acceptance of the proof-rolling, the subbase may be installed
and graded. Following same, measurements should be made to verify
proper placement. The Town representatives should be contacted to
observe such measurements.
G.
Should any soft areas in the subgrade be identified during the proof-rolling,
all such areas shall be remediated to the satisfaction of the Highway
Superintendent and Engineer for the Town. Corrective measures include,
but are not limited to, over-excavation and placement of bulk and
graded material, installation of geotextile materials, installation
of supplemental drainage, all as required to correct the condition
to the satisfaction of the Town representatives. Re-proof-rolling
may be required in the areas of the corrective work to verify correction
of the deficiency noted.
H.
Verify proper elevation prior to paving. Adequate curb reveal must
exist to result in proper pavement thickness (after rolling) with
the standard six-inch curb reveal. The crown of the roadway will also
be checked. Grade and slope should be verified for positive drainage
and compliance with design plans. Developers/contractors are strongly
advised to check the finish grading themselves prior to calling for
an inspection by the Town.
I.
At this time, and also prior to any request for a reduction in the
performance security for the public improvements, the developer/contractor
should submit draft as-builts from a licensed land surveyor (final
as-builts are to be submitted prior to dedication). All subsurface
utilities must be located on a plan depicting the right-of-way, curbs,
and surface (visible) improvements, with a minimum of two ties (to
fixed improvements) to all subsurface elements (valves, services,
tees, bends, etc.). Size, type and depth of all piping should be identified.
Also, any final test results or certifications necessary from the
design engineer should be on file with the Town at this time.
J.
After all of the above is completed, base and/or binder course paving
can be scheduled. Representatives of the Town Highway Superintendent
and Engineer for the Town must witness all paving. Following paving,
measurements will be made to verify uniform and acceptable curb reveal
and crown on the roadway.
K.
Finish course paving should not be scheduled or installed until such
time as the majority of project construction work has been completed,
such that the potential for damage to the finish course pavement is
minimized. Timing for the placement of finish paving is subject to
Town approval.
L.
Monuments shall not be set until such time that all the improvements
have been installed and all finish grading is complete.
M.
This sequence and information are a general outline of requirements
necessary for roadway construction within the Town. Additional details
and requirements of construction are noted under these street specifications,
and additional site-specific and project-specific requirements may
apply as may be determined at the discretion of the Town Highway Superintendent
and Engineer for the Town.
A.
All work
performed under this section shall be performed in a sequence and
manner so as to conform to the required sequence of construction as
noted hereinabove.
B.
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 Highway Superintendent and Engineer for the Town.
The offeror shall properly dispose of all waste materials (stumps,
roots, etc.) off site.
C.
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
Highway Superintendent and Engineer for the Town. 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 and backfills under roadways shall be made with foundation
course material meeting or exceeding the requirements of Subbase Gradation
Type No. 3 subbase material as specified under Section 304 of the
New York State Department of Transportation Standard Specifications,
Construction and Materials (latest revision), or other acceptable
material as accepted by the Town Highway Superintendent and the Engineer
for the Town. Such fills shall be made in layers of not more than
12 inches each and properly compacted with a ten-ton roller or equivalent.
D.
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.
E.
If, in the opinion of the Town Highway Superintendent and the Engineer for the Town, 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 offerer, at his/her own expense, shall provide such fabric for those areas and for the length of roadway as determined by the Superintendent and Engineer. Stabilization fabric shall meet the requirements as called for under § A63-18 of these specifications.
F.
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 Highway Superintendent and Engineer for the Town before the
foundation course is laid. No large stones or rock ledges shall protrude
into the foundation course.
G.
Should it become necessary, as part of the construction work, to
perform blasting, the same shall only be done following notification
to the Town Highway Superintendent, Town Code Enforcement Officer
and Engineer for the Town. The Town shall assume no responsibility
or liability pertaining to any blasting work. Prior to any blasting,
the blasting contractor shall obtain any permits required from the
Code Enforcement Officer and shall submit an insurance certificate
for the type work, in an amount no less than $2,000,000, 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
by the Code Enforcement Officer. Blasting shall not be performed weekends
or on legal holidays.
H.
Also, before the foundation (subbase) 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 Highway Superintendent, the Engineer
for the Town and the applicable Water/Sewer Superintendent(s). 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.
A.

E.
Installation of pipes.
(1)
The width of the trench in which the pipe is laid shall be sufficient
to permit thorough tamping of the backfill around the pipe. A cushion
of at least six inches of subbase material (NYSDOT Item No. 4), sand
or washed crushed stone shall be laid in line with grade prior to
laying the pipe. No stones over three inches maximum dimension shall
protrude or lay in this cushion. The soil below the cushion shall
be stable enough that there will be no settlement of pipe after backfilling
the trench.
(2)
The pipe shall be laid to true line and grade on the prepared bed
of the trench. All connections for pipe shall be furnished and installed
per manufacturer's recommendations. In unimproved easement areas,
backfilling of the trench shall be done with run-of-bank gravel or
other suitable material approved by the Town Highway Superintendent
and the Engineer for the Town. Within improved easement areas, or

material. The backfill shall be made in layers of no more than 12
inches, which shall be tamped and tested where required by the Superintendent
and Engineer.
(3)
All drainage pipes and structures shall be of a size sufficient to
carry natural water runoff and stormwater and also which, in the opinion
of the Town Highway Superintendent and the Engineer for the Town,
are acceptable based on the design criteria noted hereinabove this
section and which may be reasonably anticipated from future construction,
both from within the development and from adjoining properties which
normally drain across the area of the proposed development. Additional
or larger culvert pipes and drainage structures shall be installed
and paid for by the offeror if, in the opinion of the Town Highway
Superintendent and Engineer for the Town, the same is deemed appropriate
and in the best interest of the Town.
F.
Groundwater. If, in the opinion of the Town Highway Superintendent
and the Engineer for the Town, it is necessary to intercept and carry
away groundwater within the limits of the right-of-way to protect
the stability of the road bed, curb or sidewalk areas, such supplemental
subsurface and/or surface drainage improvements shall be required
and shall be installed by the offeror fully at his expense. Porous
wall concrete pipe or perforated PVC pipe having a minimum diameter
of four inches (or larger is required), encased in 12 inches of three-fourths-inch
clean crushed stone or crushed gravel (wrapped with filter fabric),
shall be used for such purpose for a length as deemed necessary by
the Town Highway Superintendent and the Engineer for the Town. Pipe
outlet location shall be as acceptable to the Superintendent and Engineer.
