[Adopted 5-28-2008 by L.L. No. 2-2008]
In his written certification, the Town's professional
engineer or qualified licensed land surveyor shall state clearly that
he has inspected all phases of the construction, and that all work
has been completed in accordance with the approved plans and specifications.
A. A plan of the proposed street shall be prepared by
a qualified professional engineer or qualified land surveyor licensed
by the State of New York. The plan shall clearly define the limits
of the proposed right-of-way by metes and bounds and shall include
the location, widths, profiles and grades of the proposed roadway,
storm drainage, including culverts and other drainage structures,
and the locations of all easements and utilities. The plans shall
also include the owner of the property and the name of the developer,
if other than the owner. One copy each of the plans shall be submitted
to the Town Highway Superintendent and Town Engineer at the time of
application to make such road a Town road, and to the New York State
Department of Transportation or Orange County Department of Public
Works when said proposed street drains toward, intersects or may otherwise
affect a state or county highway. As applicable, the plans shall be
submitted to the Town Planning Board for review and approval under
the applicable subdivision 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. Such roadway must
be granted to the Town by a full covenant and warrantee deed containing
the correct metes and bounds description as shown on the approved
map, which deed must be in such form as may be required to entitle
the same to be recorded in the office of the County Clerk of Orange
County, and the filing fees must be paid by the applicant.
B. When required, 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 outlets and easement will carry
such water. A minimum width of easement of 30 feet shall be required
for the maintenance of said easements of stormwater, water or sewer
improvements.
C. The proposed roadway must be constructed to conform
to the minimum requirements 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 person or firm
proposing such road.
D. Alteration of approved plans. Plans submitted shall
not be altered or amended after having been approved by the Town unless
an amended plan is resubmitted and approved. However, the developer,
at his own expense, shall provide additional storm drainage facilities
or utilities as may be ordered by the Town, if during the course of
construction, in the opinion of the Town Highway Superintendent, the
Town Engineer and/or the County Department of Public Works and New
York State Department of Transportation, such additional structures
or facilities are necessary to prevent any need for future pavement,
future maintenance of right-of-way or welfare and safety of the public,
except that the Town Planning Board may vary the requirements of such
an order where there are practical difficulties in the way of carrying
out to the letter of such order; unless such variance conflicts with
the provisions of a Town or County Official Drainage Map, in which
event, the Official Map shall prevail. If construction of said road
has not been started within one year from the date of final approval
by the Town Planning Board, plans shall be resubmitted and approved
as above. If these specifications are amended prior to start of construction,
the developer will be required to comply with updated requirements,
unless waived by the Town.
The provisions of this article supersede all
prior regulations, specifications and ordinances covered by the subject
matter of this article.
[Amended 9-2-2009 by L.L. No. 2-2009]
A. As provided in §
120-47 of the Subdivision Regulations herein, the developer shall complete all construction within the right-of-way, including roadway, shoulders, curbs, if any, gutters, storm drainage, as well as any and all public improvements required by the approved subdivision plans, for each lot within the subdivision, and the developer shall adequately document that all claims for labor and materials in connection with said construction shall have been paid in full prior to offering said road or other public improvement for dedication to the Town.
B. Upon certification
by the developer’s professional engineer or qualified licensed
land surveyor and acceptance by the Town Engineer that the construction
of the street or other required public improvement has been completed
in accordance with the approved plans and specifications, the developer
will offer to the Town Board for dedication the completed street and
all other related improvements for public use free and clear of any
liens and encumbrances. This guarantee of dedication shall apply to
the owner of the property as well as the developer where the two are
not the same.
C. Prior to
commencement of any work, the developer shall make payment to the
Town for all inspection fees associated with the work that is required
in accordance with the Standard Schedule of Fees and the subdivision regulations.
D. Prior to
acceptance by the Town of any public improvement, the developer shall
file with the Town Clerk a maintenance bond in an amount established
by the Town Board. The amount of the maintenance bond shall be adequate
to assure the satisfactory condition of the initial public improvements
for a period of two years following their completion and acceptance
by the Town Board. Such bond shall be in the form of a bank or certified
check deposited with the Town or a letter of credit by a duly licensed
lending institution authorized to do business in the State of New
York and having an office for the transaction of business in New York.
The letter of credit must provide that any demands made thereon may
be made at the Orange County, New York, location of the institution
issuing the letter of credit. The maintenance bond is further subject
in all respects to the review and approval of the Town Attorney. The
developer will, at his own expense, repair and make good any defects
or damage which may develop during this maintenance period as a result
of faulty design and/or construction within the right-of-way or as
a result of other construction by the developer outside the right-of-way.
During the maintenance period, the Town shall be responsible for snow
and ice control, street cleaning and cleaning of culverts and catch
basins, as well as other work of a familiar and routine nature, provided
that such work has in no way been caused or contributed to by the
developer’s operations.
The Town Planning Board and Planning Board Engineer
shall determine and designate into which of the three following classifications
each proposed subdivision street falls on the basis of the criteria
hereinafter set forth:
A. Suburban street: collector or local.
The following criteria shall be used to determine
what classification shall be given to a street:
A. Suburban street: collector.
(1) The proposed street is the principal collector for
300 or more homes in the neighborhood.
(2) The proposed street could logically be expected to
become a major street because of future construction or other foreseeable
circumstances.
(3) The proposed street is the direct and logical continuation
of a street that carried 500 or more cars during a twelve-hour period,
as shown on the latest traffic count.
(4) The proposed street creates a shorter and more convenient
through-traffic artery so that it can be reasonably expected that
traffic will be diverted from other major streets to such an extent
that it will reach at least 500 cars in 12 hours within two years
after opening.
B. Suburban street: local.
(1) The proposed street will serve residential subdivisions
with lot sizes of less than one acre and more than 10 lots to be developed
in the subdivision.
(2) The proposed street is in an area zoned for commerce
or industry.
(3) The proposed street is on or close to the dividing
line between a residential and a commercial or industrial area so
that it may reasonably be expected to carry a substantial volume of
commercial or industrial area and a major traffic artery.
C. Rural street. The proposed street will serve residential
subdivisions.
D. The right-of-way width for internal roads and alleys
in multifamily, commercial and industrial developments shall be determined
on an individual basis and shall in all cases be of sufficient width
and design to accommodate safely the maximum anticipated traffic,
parking and loading needs.
E. Improvements. Streets shall be graded and improved
with pavements, curbs and gutters, sidewalks, storm drainage facilities,
water mains, sewers, streetlights and signs, street trees and fire
hydrants, except where waivers may be requested, and the Planning
Board may waive, subject to appropriate conditions, such improvements
as it considers may be omitted without jeopardy to the public health,
safety and general welfare. Curbs, gutters, sidewalks, street pavements,
fire hydrants, streetlights, shade trees, monuments, water mains,
storm sewers, sanitary sewers and any other improvements that may
be required shall be designed and constructed to conform to the specifications
as established by resolution or ordinance of the Town Board. Pedestrian
easements shall be improved as required by the Town Engineer. All
rights-of-way shall be provided with paved, seeded or sodded areas,
properly prepared, graded and sloped in conformance with good practice.
Such grading and improvements shall be approved as to design and specifications
by the Town Engineer.
F. The detail sheets (located in
Appendix A) show the cross sections of each of the classifications
for Town streets. These give the required design dimensions and construction
details which are applicable to each classification. The general and
more detailed specifications for design and construction which are
applicable to both classifications of streets follow. The developer
shall design and construct streets which shall conform to both the
general and specific specifications.
A. New streets. Streets shall meet the design standards
set forth in the following table. Street classification may be indicated
on the Town Development Plan or may be determined by the Planning
Board.

B. Sight distance requirements. All street and driveway
intersections shall meet the standards contained in the New York State
Department of Transportation publication entitled, "Policy and Standards
for Entrances to State Highways" (February 1998) or latest edition.
More specifically, said intersections shall, at a minimum, meet the
intersection sight distance (ISD) requirements in Tables 3 and 4 of
said publication. Notwithstanding the above, driveways which cannot
meet the ISD requirements shall, at a minimum, meet the stopping sight
distance (SSD) requirements in Table 5 of said publication.
C. Intersections.
(1) Intersections of major streets shall be at least 800
feet apart, if possible. Cross (four-cornered) street intersections
shall be avoided insofar as possible, except at important traffic
locations. A distance at least equal to the minimum required lot width,
but not less than 150 feet, shall be maintained between center lines
of offset intersecting streets. Within 60 feet of the center of an
intersection, streets shall be at approximately right angles and grades
shall be limited to 1.5%. All street intersection corners shall be
bounded by curves of at least 25 feet in radius at the property line.
Wherever two streets intersect at an angle of less than 75°, special
pavement, channelization, right-of-way and/or sight easement restrictions
may be required.
(2) All intersections with existing Town, county, or state
roads shall be constructed with the edge of pavement having a radius
of 25 feet maximum. Intersections within the development shall be
constructed with edge of pavement having a radius of 25 feet minimum
and 35 feet maximum.
(3) The grade of the intersecting street with a Town,
county, or state road shall be no more than 2% within 50 feet from
the edge of the shoulder of the Town, county, or state road to the
right-of-way or road line of said road.
(4) Angle of intersection. In general, all streets shall
join each other so that for a distance of at least 100 feet the street
is approximately at right angles to the street it joins, and in no
case shall two streets intersect at an angle smaller than 60°.
To this end, an oblique street should be curved approaching an intersection.
Where three or more streets intersect, a traffic circle or other special
treatment may be required by the Board.
D. Grades and vertical curves.
(1) The grade of the street shall not be in excess of
8% nor less than 1% for collector streets, nor more than 10% nor less
than 1% for local streets. By permission of the Planning Board and
the Town Engineer only shall a grade of more than 10% be allowed due
to topographic conditions. In no case shall the grade exceed 12% without
special exception by resolution of the Planning Board. Difference
in grade will be affected with a vertical curve of sufficient length
to allow a stopping sight distance of no less than 250 feet, based
on a driver's eye height of 3.5 feet elevation, and an object height
at six inches elevation. Grades shall be limited to no more than 2%
within 50 feet of an intersection.
(2) Changes in grade. All changes in grade shall be connected
by vertical curves of such length and radius as meet with the approval
of the Town Engineer so that clear visibility shall be provided for
a safe distance as well as a smooth transition.
(3) In order to provide visibility for traffic safety,
that portion of any corner lot (whether at an intersection of a new
street or an existing street) shall be cleared of all growth (except
isolated trees) and obstructions above the level three feet higher
than the center line of the street for a distance of 20 feet from
the point of tangency on either side of the intersection curve. If
directed, ground shall be excavated to achieve visibility.
(4) Curve radii. In general, street lines within a block
deflecting from each other at any one point by more than 10° shall
be connected with a curve, the radius of which for the center line
of street shall not be less than 250 feet on collector streets and
100 feet on local streets. The outer street in each case shall be
parallel to such inner street line. A tangent of at least 150 feet
long shall be introduced between reverse curves on arterial and collector
streets.
E. Cul-de-sacs (dead-end street). Cul-de-sacs shall be equipped with a turnaround roadway with a minimum diameter of right-of-way of 150 feet with a minimum outside diameter of traveled way of 130 feet (detail located in
Appendix A). The radii of the curves entering into and exiting from
the cul-de-sac shall be a minimum of 50 feet. Cul-de-sacs shall be
graded to allow for positive drainage to the curblines. The minimum
grade through the cul-de-sac, as determined along the curbline, shall
be 1%. The maximum grade through a cul-de-sac, as determined along
the curbline, shall not exceed 5%. A twenty-foot-by-twenty-foot snow
storage easement shall be provided at the end of a cul-de-sac.
F. Driveways.
(1) Developers and home builders shall design and construct
all driveways within the limits of the right-of-way with sufficient
sight distance (in both directions) and with a grade no more than
one inch per foot from curb to the right-of-way line. The minimum
width of the driveway pavement at the curb or street pavement line
shall be 15 feet, tapering to a minimum of 10 feet at the right-of-way
line. All driveways shall have a six-inch run-of-bank gravel foundation
course from curb to right-of-way line and no less than three inches
of hot-mix asphalt concrete wearing course from curb or street pavement
line to a point 25 feet from the curb or street pavement line, which
shall be applied during or after the laying of the street pavement.
(2) All driveways shall be graded so as to slope away
from the Town road at 1/2 inch per foot for a minimum of four feet,
then at a slope of one inch per foot to the right-of-way line. Grading
shall be to the satisfaction of the Town Highway Superintendent and
the Town Engineer prior to the surfacing of such driveways. Maximum
allowable driveway slope shall be 10%. Where required by the Town
Highway Superintendent, a culvert or drainage system shall be provided,
with the pipe size and material to be as acceptable to the Town Highway
Superintendent. Pipe size shall not be less than 15 inches in diameter,
and shall have a minimum coverage of 12 inches over the pipe.
(3) All driveways that have received a waiver from the
Planning Board to allow any portion of said driveway to have a slope
over 10%, which in any case may not exceed 12%, shall be paved for
the entire length of the driveway.
(4) All driveways that exceed 250 feet in length must
provide a turnaround area sufficient for emergency vehicles as well
as provide at least one area of the driveway that is wide enough for
two emergency vehicles to simultaneously pass one another.
The developer shall establish and clearly mark
on a site the limits or road rights-of-way and easements with concrete
monuments, and grades of the finished road pavement, and the locations
and elevations of drainage structures, as shown on the approved plans,
with constructions stakes. Such construction of road pavement, drainage,
structures, curbs, and shoulders shall be completed, inspected and
approved by the Town Engineer at each step of construction. The developer
shall be responsible for scheduling the work so as to coordinate all
necessary inspections. Permanent concrete monuments shall be set on
right-of-way lines of streets at all intersections, angle points,
points of curvature and beginning and end of streets and at three
points of all cul-de-sacs. 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 streets. The permanent markers shall be
made of concrete with minimum dimensions of 30 inches long, four-inch
square top and six-inch square bottom, with a one-half-inch drilled
hole in the top. Concrete monuments shall have a No. 3 rebar in the
center of it for ease of future location. If a monument should be
located in a rock edge, the surface shall be stripped and a one-half-inch
steel rod drilled into the ledge. Monuments shall protrude two inches
above the final graded surface. The developer's licensed surveyor
shall certify that the location of all monuments is accurate before
acceptance of the street by the Town Board.
A. Drainage easements. Where surface water from the road
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 30 feet shall be provided to a point where
a natural watercourse exists. In some cases, this may include easements
over property outside the boundaries of the subdivision involved.
Natural stream or ditch channels shall have a minimum of thirty-foot-wide
permanent easements and be shown on the proposed plans of a subdivision.
All permanent easement lines shall be monuments as a right-of-way.
B. Sight easements. Sight easements shall be provided
across all road corners, outside the road right-of-way, within the
triangular area formed by the nearest edges of street pavement and
a straight line between two points each 25 feet back from the theoretical
intersection of the edges of such pavement prolonged. The easements
shall provide that the holder of fee title to the abutting streets
shall have the right to enter the easement area for the purpose of
clearing, pruning or regrading so as to maintain a clear line of sight
in either direction across such triangular area between an observer's
eye 3.5 feet above the pavement surface on one street and an object
one foot above the pavement surface on the other. The initial establishment
of clear sight lines within the sight easement area shall be the responsibility
of the subdivider.
A. Prior to commencement of work, the developer shall
have all roads and easement areas staked and shall meet with the Town
Engineer to determine the extent of clearing and grubbing and whether
or not any existing vegetation within these areas are to remain. Otherwise,
the developer shall clear the entire area within the limits of:
(2) Stream channels and ditches.
(3) All ledge rock and rock outcroppings shall be removed
to below the elevation of the lowest point of the roadbed and shall
be done to afford proper sight distances, drainage and runoff.
(4) Easement areas (as determined by the Town Engineer).
B. All stumps, roots, walls, structures, abandoned utilities,
and debris shall be excavated and removed from the above areas.
A. The developer shall complete the shaping of the road
right-of-way, streams and ditches and easement areas to the line and
grade as shown on the approved plans and as otherwise may be directed
by the Town Engineer. In the construction of the roadway, all topsoil,
loam, rocks and organic materials shall be removed until a satisfactory
subbase is established. All fills shall be made with acceptable material
as approved by the Town Engineer. Such fill shall be made in layers
of not more than eight inches each and properly compacted with a ten-ton
roller or equivalent.
B. 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 Engineer before the foundation course is
laid. No large stones or rock ledges shall protrude into the foundation
course.
C. Also, before the foundation course is laid, all storm
drainage and catch basins, manholes, and all utilities shall have
been installed and all excavations and trenches, exclusive of pipe
bedding, shall be backfilled with Item 4 (NYSDOT Item 304.03) to the
satisfaction of the Town Engineer. All sloped areas shall be graded
before the foundation course is made and all loose and exposed stones
shall be removed.
D. Stakes with final line and grade shall be maintained
by the developer at all times to check the foundation course, as well
as pavement.
A. Before fine grading or construction of curbs is started,
all storm sewers and all utilities shall have been installed and all
fill and backfill shall have been thoroughly compacted to the satisfaction
of the Town Engineer.
B. Also, before fine grading or construction of curbs
is started, all heavy trucking for building or site construction purposes
shall have been completed.
C. After completion of the rough grade and prior to the
laying of the foundation course, the subgrade shall be shaped to line
and grade and thoroughly compacted with an approved self-propelled
roller weighing not less than 10 tons. All hollows and depressions
which develop under rolling shall be filled with acceptable granular
material and again rolled, this process to be continued until no depressions
develop. The subgrade shall not be muddy or otherwise unsatisfactory
when the foundation course is laid upon it.
D. Any soft, unstable, or unsuitable portions of the
subgrade which develop under "proof rolling" with a fully loaded tandem
dump truck 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. Prior to installation of foundation course, a nonwoven
needle-punched geotextile fabric shall be laid upon the subgrade along
the entire length of the proposed roadway. Geotextile fabric shall
be overlapped 18 inches minimum at all seams. Geotextile fabric shall
meet the following minimum properties, in accordance with ASTM test
methods:

F. 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. After the fine grade and all curbs have been constructed
to the satisfaction of the Town Engineer, the developer shall furnish
and place a foundation course of New York State Department of Transportation
(NYSDOT) Item No. 304.03 to the depth of 12 inches as called for in
these sections. All materials acceptable for this course shall be
hard, durable and sound and shall be well graded from coarse to fine,
the maximum diameter of the large particles not exceeding two inches;
25% to 60%, by weight, shall pass the one-quarter-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 sieve. A certified analysis
of granular material will be filed with the Town Engineer.
B. The materials shall be placed on the finished subgrade
by means of mechanical spreaders and shall be thoroughly compacted
by rolling with a self-propelled ten-ton roller. Water shall be added
to the materials in such amounts as the Town Engineer may consider
necessary for proper compaction. After compaction, the course shall
be true to grade and cross sections, and depressions shall be eliminated
by the use of additional granular material thoroughly rolled in place.
In all cases, the foundation course must be thoroughly compacted so
that it will not weave under the roller.
C. The subbase and foundation course shall lie a minimum
of three months to allow complete settlement before the pavement is
laid. Prior to placement of any pavement, all roadways shall be "proofed-rolled"
with a fully loaded tandem dump truck in the presence of the Town
Engineer, in a manner prescribed by the Town, and any defective or
unacceptable sections shall be reconstructed as necessary and retested
prior to paving operations.
A. The drainage system and/or culverts shall be designed
in accordance with established engineering principles and approved
by the Town Engineer. Plans for any drainage structure other than
pipe culverts, when existing or proposed, shall be submitted in detail
to the Town Engineer for approval. The minimum grade of any drainage
pipe or culvert shall not be less than 1%. The approved plans shall
show invert elevations of the inlet and outlet of all drainage structures.
Any deviation from the approved plans shall be on approval of the
Town Engineer, in writing. No culvert pipe shall be less than 18 inches
in diameter unless by approval of the Town Engineer. Pipe for culverts
may be high-density polyethylene pipe (HDPE) which shall conform to
the last ASTM and AASHTO standards, or where approved, reinforced
concrete pipe may be permitted. End sections shall be placed at all
pipe inlet or outlet ends, where appropriate. Where required, headwalls
of concrete or mortared stone masonry shall be constructed. Culverts
shall extend to the toe of embankment. The bearing of all headwalls
shall have a solid base. If soft material is encountered, it shall
be removed and backfilled with NYSDOT Item No. 304.03. It shall be
the responsibility of the developer that no headwalls shall crack
or become tipped from settlement. A concrete mix of 4,000 psi after
28 days shall be used.
B. The width of the trench in which the pipe (see trench detail in
Appendix A) is laid shall be sufficient to permit thorough compaction
of the backfill around the pipe and a minimum of 24 inches wider than
the pipe diameter. A cushion of at least six inches shall be laid
in line with grade prior to laying the pipe. No rock over three inches
in size shall protrude or lie in this cushion. The soil below the
cushion shall be stable enough so that there will be no settlement
of pipe after backfilling the trench.
C. The pipe shall be laid to true line and grade on the
prepared bed of the trench. Backfilling of the trench shall be done
with roadway foundation material approved by the Town Engineer. The
backfill shall be made in layers of no more than six inches, which
shall be compacted. In no case shall the top of any drainage pipe
be less then 24 inches below the finished grade of pavement. Alignment
of pipes shall be in a straight line between drainage structures.
D. All drainage structures (pipes, basins, etc.) shall be of a size sufficient to carry natural water runoff and stormwater and also that which, in the opinion of the Town Engineer, may be reasonably anticipated from future construction, both from within the development and from adjoining properties, which normally drain across the area of the proposed development. Sizing of all structures shall comply with the Town guidelines in effect at the time of construction. Additional or larger culverts and drainage structures shall be installed and paid for by the developer if the Town Engineer so directs. Drainage structures (catch basin detail located in
Appendix A) shall be backfilled with NYSDOT Item No. 304.03. Backfill
material shall be "chucked" under the piping to ensure all voids are
filled so as to prevent settlement. Backfill material shall be compacted
in six-inch lifts around catch basin structures with a vibratory "jumping
jack" compactor.
E. With the approval of the Town Engineer, open ditches
may be used in lieu of storm drain pipes when the grade of the land
traversed is flat or when it is desirable to drain and dry up the
surrounding area. All open drainage lines and swales shall be protected
against erosion by suitable stabilizing materials or construction.
(1) The grade of any open ditch shall not exceed 6%. Rip-rap,
when called for, shall consist of rough, unsewn quarry stones as nearly
cubical in form as is practicable, placed upon a slope not steeper
than 1:2 and so laid that the weight of the larger stones is carried
by the soil and not the stone adjacent.
(2) The largest stones shall be placed first, roughly
arranged and in close contact. The spaces between the larger stones
shall be filled with spalls of suitable size.
(3) Whenever a drain pipe enters an open ditch, the bottom
and sides of the ditch shall be rip-rapped for a distance of at least
30 feet beyond the end of the pipe. The drainage pipe shall terminate
at a headwall.
A. If, in the opinion of the Town Engineer, it is necessary
to intercept and carry away groundwater within the limits of the right-of-way
to protect the stability of the roadbed, curb or sidewalk areas, the
subdrainage required by the Town Engineer shall be installed. PVC
perforated pipe, having a minimum diameter of four inches, shall be
encased in three-quarter-inch clean crushed stone, within a trench
that is 12 inches wide. Entire subdrainage shall be wrapped in a nonwoven
geotextile fabric having a water flow rate of 155 gpm/ft2, a fabric thickness of 50 mils, Mullen burst strength
of 170 psi, and a grab strength of 90 pounds. Trench filled with crushed
stone shall start at a point four inches below finished grade, allowing
for four inches of topsoil. Trench shall extend down so that the top
of the subdrainage pipe shall be positioned two inches below the bottom
of the curbline. There shall be at least four inches of crushed stone
under the perforated pipe. If curbing is not to be installed, top
of subdrainage pipe shall be installed 24 inches below finished pavement
grade.
B. Roof, cellar and footing drains shall in no case be
allowed to flow onto the street right-of-way. With the approval of
the Town Engineer, in writing, these drains may be piped to existing
stormwater structures, if any, to which they will be connected. Such
drains must be installed prior to the start of the application of
the foundation course. Drains from septic tanks will not be permitted
to flow into road ditches or storm drains under any circumstances.
A. Street signs of a type approved by the Town Highway Superintendent and the Town Engineer shall be installed by the developer. All names are subject to the approval of the Town Board in accordance with §
120-67. The developer shall also install all required traffic controls signs, as recommended by the Town Highway Superintendent and the Town Engineer, subject to the approval of the Town Board.
B. Signs shall be double-faced, assembled with engineer-grade
reflective sheeting on extruded aluminum blades. Signs shall be white
characters on green background, six inches in height by length as
necessary for specific installation. Letters shall be three inches,
upper case, FHWA Series C, of reflective sheeting. All signs shall
