compacted to provide adequate support for the piping.
(6)
Excavations must be kept free of water by pumping,
underdrains or other approved means during pipelaying operations,
so that all pipe joints and manholes are installed in the dry.
(7)
In areas of rock excavation, pipe shall be placed
on six inches of sand or gravel.
(8)
Widths of trench shall not exceed two feet zero inches,
plus outside diameter of pipe, measured at the top of pipe.
(9)
After the pipe work is completed and when directed
by the Engineer or Street Superintendent, the area shall be backfilled
with materials specified below to bring entire area to grade.
(10)
The backfill shall be placed by hand and thoroughly
compacted by hand; under and around the pipe shall be machined up
to the pipe center line and then shall be carefully deposited, in
layers not to exceed six inches in thickness, and thoroughly and carefully
compacted by a hand machine up to a cover of not less than one foot
above top of pipe. Soil shall be compacted to a density of not less
than 95% of modified American Association of State Highway Officials
standards. See Attachment A.
(11)
Backfill material shall be clean, excavated
earth, sand or other suitable material. Under no circumstances shall
rubbish, waste lumber, boulders or broken masonry more than six inches
in largest dimensions, or any other unsuitable material, be contained
in the backfill material.
(12)
Backfilling above the top of pipe shall be done
in even layers not exceeding 12 inches in thickness before compaction.
Each layer shall be compacted to a density of not less than 95% of
modified American Association of State Highway Officials standards.
(13)
All pipe shall be kept clean. All exposed ends
of all incomplete lines shall be closed with plugs when pipelaying
is not actually in progress.
(14)
Precautions shall be taken to protect incomplete
work from floating due to storms or other causes.
(15)
All work shall be done in conformance with Occupational
Safety and Health Administration and the New York State Construction
Safety Code.
H.
Testing.
(1)
All testing shall be done at the expense of the developer,
including furnishing necessary test equipment and apparatus.
(2)
Gravity pipe shall have a full pipe cross section
visible and unobstructed when viewed from manhole to manhole.
(3)
Testing for leakage shall be done by infiltration,
exfiltration or air tests at the discretion of the Street Superintendent,
each as described below:
(a)
Infiltration. When groundwater levels are at
least two feet above the top of pipe for entire length of section
under test, flow shall be measured over a watertight weir at the end
of the section. The duration of the test shall be two hours. Leakage
shall not exceed 200 gallons per day, per inch-diameter, per mile.
(b)
Exfiltration. The pipe and manhole shall be
filled with water to provide a head of at least two feet above the
top of the pipe at the highest point in the section under test. The
loss of water shall be measured for at least two hours. Leakage shall
not exceed 150 gallons per day, per inch-diameter, per mile.
(c)
Air. Following a wetting of the pipe surface
and checking for tightness of all connections, a constant four pounds
per square inch shall be obtained. Air supply shall be shut off and
pressure allowed to drop to 3.5 pounds per square inch. The pressure
drop shall be timed from three and 3.5 pounds per square inch to two
and 2.5 pounds per square inch. Time shall not exceed three minutes
57 seconds for eight-inch pipe, and four minutes 43 seconds for ten-inch
pipe.
(4)
If the inspection and/or testing shows any part of
the system to be defective or to have leakage in excess of the allowable,
the developer shall repair the defective work and retest.
(5)
All testing shall be done in the presence of and to
the satisfaction of the Street Superintendent.
(6)
All sewer lines will be flushed prior to testing.
A.
Lots to be buildable. The lot arrangement shall be
such that there will be no foreseeable difficulties for reasons of
topography or other natural conditions in construction on the lot
in accordance with the Zoning Ordinance.[1] Lots shall not be of unreasonable depth which might encourage
the subsequent creation of a second building lot at the rear where
there is no rear street.
B.
Side lines. All side lines of lots shall be at right
angles to straight street lines and radial to curved street lines,
unless a variance from this rule will give a better street or lot
plan, in the opinion of the Board.
D.
Driveway access. Where practicable, lots shall be
so laid out that the driveways have access to that one of the streets
on which they abut which carries or is intended to carry the lesser
amount of traffic. Driveway grades between the street and setback
line shall not exceed 10%.
E.
Access from private, minor and collector streets.
Access from private minor and collector streets shall be deemed acceptable
only if such streets are designed and improved in accordance with
these regulations.
F.
Access from major streets. Lots shall not, in general,
derive access exclusively from a major street. Where driveway access
from a major street may be necessary for several adjoining lots, the
Planning Board may require that such lots be served by a combined-access
drive in order to limit possible traffic hazard on such street.
A.
The following improvements are required except where
specifically waived by the Planning Board as provided in § 10
above.
(1)
Paved streets, curbs and gutters.
(2)
Street signs and lighting devices.
(3)
Sidewalks. Pedestrian easements shall be improved
in accordance with design and specifications approved by the Planning
Board.
(4)
Shade trees, to be located on the street line so as
not to interfere with utilities or sidewalks, which shall be of the
types recommended by the Village, planted in accordance with the applicable
Village specifications.
(5)
Topsoil protection. No topsoil shall be removed from
the site or used as spoil. Topsoil moved during the course of construction
shall be redistributed so as to provide at least six inches of cover
to all areas of the subdivision and shall be stabilized by seeding
or planting.
(6)
Water mains, fire hydrants, culverts, storm sewers
and sanitary sewers. All such installations shall be properly connected
with an approved system and shall be adequate to handle all present
and probable future development. They shall be designed to satisfy
the minimum specifications of the State Health Department. A note
to this effect shall be stated on the plat by the engineer.
B.
C.
Utilities in streets. The Planning Board may require
that underground utilities be placed in the street right-of-way between
the paved roadway and street line to simplify location and repair
of lines when they require attention. The subdivider shall install
underground service connections to the property line of each lot within
the subdivision for such required utilities before the street is paved.
D.
Utility easements. Where topography is such as to
make impractical the inclusion of utilities within the street lines,
perpetual unobstructed easements at least 20 feet in width shall be
provided across property outside the street lines and with satisfactory
access to the street, other public right-of-way or open space shown
on the plat or the Official Map. Wherever possible, easements shall
be continuous from block to block and shall present as few irregularities
as possible. Such easements shall be cleared and graded where required.
A.
Removal of spring- and surface water. The subdivider
may be required by the Planning Board to carry away by pipe or open
ditch any spring- or surface water that may exist either previous
to or as a result of the subdivision. Such drainage facilities shall
be located in the street right-of-way, where feasible or in perpetual
unobstructed easements of no less than 20 feet in width.
B.
Drainage structure to accommodate potential development
upstream. A culvert or other drainage facility shall, in each case,
be large enough to accommodate potential runoff from its entire upstream
drainage area, whether inside or outside the subdivision. The Village
Engineer shall approve the design and size of facility based on anticipated
runoff from a ten-year storm under conditions of total potential development
permitted by the Zoning Ordinance[1] in the watershed.
A.
Parks.
(1)
The Planning Board shall require that the plat show
sites of a character, extent and location suitable for the development
of a park, playground, open space or other recreation purpose.
(2)
Ten percent of the gross area of any major subdivision
shall be left as open space, parks, playground or other recreational
area. Such area or areas may be dedicated to the Village by the subdivider
if the Village Board accepts such dedication. Any area(s) to be dedicated
to Sullivan County must be approved by the County Board of Supervisors.
(3)
It is the intent of this local law that open space
within a subdivision shall be contiguous to the maximum extent feasible.
B.
Information to be submitted. In the event that an
area to be used for a park or playground is required to be so shown,
the subdivider shall submit, prior to final approval, to the Board
three prints [one on Mylar] drawn in ink, showing, at a scale of not
less than 30 feet to the inch, such area and the following features
thereof:
(1)
The boundaries of said area, giving lengths and bearings
of all straight lines and radii, lengths, central angles, tangent
distances and radial bearings of all curves. All lengths shall be
in feet and hundredths of a foot, and all angles shall be given to
the nearest 10 seconds. The error of closure shall not exceed one
to 10,000.
(2)
Existing features such as brooks, ponds, beaches,
marches, areas subject to flooding, clusters of trees, the location
of any trees with a diameter of 12 or more inches as measured three
feet above the base of the trunk, rock outcrops and structures.
(3)
Existing contours at five-foot intervals and, if applicable,
proposed changes in grades and contours of area and of area immediately
adjacent.
(4)
Any existing or proposed easements or proposed deed
restrictions.
C.
Waiver of plat designation of area for parks and playgrounds.
(1)
In cases where the Planning Board finds that due to
the size, topography or location of the subdivision, land for park,
playground or other recreation purposes cannot be properly located
therein or, if in the opinion of the Board, it is not desirable or
necessary, the Board may waive the requirement that the plat show
land for such purposes. The Board shall then require as a condition
to approval of the plat a payment to the Village not to exceed the
value of the land which otherwise would have been acceptable as a
recreation site. Land value is to be determined by applying the latest
state equalization rate for the area to the assessed value of the
entire plat, then dividing by the number of acres in said plat to
arrive at the full value per acre of land, and by multiplying the
per acre value by the number of acres required; or the Planning Board
may seek an impartial appraisal to determine land value.
(2)
Unless this amount is included in a performance bond,
such amount shall be paid to the Village Board at the time of final
plat approval, and no plat shall be signed by the authorized officers
of the Planning Board until such payment of cash or a letter of credit
is made. All such payments shall be held in a recreation site acquisition
and improvement fund, to be used for the acquisition of land that
is suitable for permanent park, playground or other recreational purposes
and is so located that it will serve primarily the general neighborhood
in which the land covered by the plat lies and which shall be used
only for park, playground or other recreational land acquisition or
improvement Such money may also be used for the physical improvement
of existing parks or recreation areas serving the general neighborhood
in which the plat is situated, provided that the Planning Board finds
there is a need for such improvements. Such money is not to be used
for regular and routine maintenance.
D.
School sites. Upon receipt from the School Board of
a letter declaring its interest in a school site of a specific size
and location within a proposed subdivision, the Planning Board may
require a subdivider to set aside such area. Upon the failure of the
proper authorities to purchase such school site within 36 months after
the date of the approval of the plat, the subdivider, upon application
to the Board and approval of such application, shall be relieved of
the responsibility of saving such land for public purposes and may
submit an alternate plan for use of such land.
