All land subdividers are required to construct
certain public improvements, and to ensure the performance of this
work, a bond will be required. All public improvements are to be constructed
in accordance with the current standards, details, specifications
and requirements of the Village of Lake Grove, and no work on any
of the required public improvements is to be commenced by the subdivider
or his agents until the construction plans and specifications have
been approved by the Village Engineer. Such approval will include
a stipulation that the village is to be notified at least 48 hours
in advance of the work proposed, to allow scheduling of the necessary
inspection by the village.
During the construction of the required public
improvements and during the overall development of the entire subdivision,
all existing village or county roads and streets and all adjoining
private property shall be kept free of debris caused by the construction
operations or by stormwater runoff from the development site. No existing
street shall be damaged or have its normal traffic flow restricted
or endangered in any way by equipment, material or vehicles connected
with the sale or construction of a subdivision. Adequate parking and
storage space for all vehicles, equipment and material required for
the improvement of the subdivision shall be provided by the developer.
Minimum public improvements shall be deemed
to include clearing and grading of all new streets; paving of all
streets; the installation of sidewalks in front of and in all new
plots being developed by the subdivider; the installation of curbs
on both sides of all new streets, whether or not the entire frontage
along such new street is owned by the subdivider; adequate drainage
facilities as approved by the village; sanitary sewers and/or treatment
facilities as required by county authorities; street trees and landscaping;
concrete monuments; street signs and park improvements. Additional
improvements such as timber bulkheads, grading, retaining walls, sodded
rear yard swale areas, fencing, screen planting, etc., may be required
by the Planning Board if in its opinion such additional improvements
are required in the interest of public health, safety or the general
welfare of the present and future residents of the village.
Streets shall be of sufficient width, suitably
located, related to the topography, adequately constructed to accommodate
the expected traffic, afford access of fire-fighting, snow removal
and road maintenance equipment, conform to the village's overall plan,
cause no undue hardship to adjoining properties and provide for the
orderly continuation of existing streets from adjoining properties
and for the feasible projection of necessary streets into adjoining
properties which are not yet subdivided. The creation of private streets
will be permitted only when such streets conform to all of the criteria
set forth for the creation of a public street. No street right-of-way
less than 50 feet in width will be permitted, although wider rights-of-way
may be required by the Planning Board if it deems it to be in the
best interests of the village. Minimum permitted pavement width between
faces of curb shall be 34 feet; all curbs shall have a six-inch reveal,
and the top of curb shall be equal in elevation to the center line
of the road for a fifty-foot right-of-way. At all street corners,
the intersecting street lines shall be joined by a curve having a
radius of 17 feet at the property line and 25 feet on the curbline.
Whenever the algebraic difference of intersecting vertical curves
exceeds 1%, a fifty-foot vertical curve shall be provided, and as
the algebraic difference mounts in excess of 2%, the length of vertical
curbs provided shall equal 25 times the algebraic difference. Center-line
horizontal curves shall be at least 150 feet (minimum radius), and
reverse center-line curves shall be separated by a minimum tangent
length of 50 feet. Greater minimum radii or tangent lengths may be
required if a minimum two-hundred-foot site distance cannot be obtained.
A proposed cross section indicating the type of street paving, the
width of pavement and the proposed curbs and sidewalks shall appear
on all maps submitted. Such cross section shall also indicate the
nature of all underground facilities to be installed in the right-of-way
and the relative location of each in respect to the property lines
and the depth of cover. The utilities shown shall include stormwater
drains, sanitary sewers, water mains, underground gas and electric
and any other systems proposed. In general, the materials permitted
in the construction of these improvements shall be in accordance with
the following tabulation:
A. Street pavement shall be constructed as required by
the Village Engineer and the Superintendent of Public Works.
B. Curb and sidewalk permitted. Curbs and sidewalks shall
be constructed of concrete with a one-to-two-to-four mix which shall
develop an average crushing strength of 4,000 pounds per square inch
average, with 5% air entrainment, after 28 days. Sidewalks shall be
at least four feet wide and set so that the back edge is six inches
off the property line and two inches above the elevation of the top
of the curb. They shall slope toward the street at the rate of 1/4
inch per foot. The walk shall be a minimum of four inches thick, except
at the driveways, where it shall be six inches thick, extend to the
back of curb and be reinforced with wire mesh. The curb shall be six
inches wide, 18 inches deep, smooth wood-float finished and true to
line and grade. At points where driveways provide access to the street,
the curb shall be dropped so as to finish 11/2 inches above the flow
line.
C. Water mains. Cast-iron or asbestos cement pipe of
adequate strength will be permitted. All valve boxes must be accessible
upon the completion of the final wearing course. All water mains and
appurtenances shall be fully tested prior to the completion of the
subbase preparation for the new pavement. The Board will be furnished
with a layout showing the size and placement of the water mains and
the location of the proposed hydrants for its review and approval.
Water mains and appurtenances shall be as specified and approved by
the water purveyor and the Suffolk County Department of Health, if
required.
D. Sanitary sewers. Asbestos cement or cast iron, or
other material approved by the governing county authorities.
E. Stormwater drains. Reinforced concrete pipe.
F. Manholes, catch basins and appurtenances. Precast
or poured concrete with cast-iron frames or rings, and covers (heavy
duty in paved areas) with catch basin inlets being of the combination
curb and gutter inlet type.
The drainage plan includes detailed plans of
all stormwater drainage facilities, street profiles and other utilities
which may be required by the Board or other governmental agencies.
These plans are considered to be an integral part of the final plat
submission and are therefore the basis for the setting of the performance
bonds and inspection fee. It is intended that all drainage problems
within the limits of the subdivision will be completely resolved by
the design as approved by the Board before any work is started. If
in the event of an error on the part of the designing engineer, either
of judgment or design, a drainage problem becomes apparent during
the progress of the work or after the completion of the work, the
Board reserves the right to stop the work and order the necessary
changes to correct the situation. The Board shall be held blameless
for any change so made.
The drainage plans must be prepared by a licensed
professional engineer in conformance with the design criteria and
standards contained herein and shall be submitted in final form, together
with copies of the final plat, at least 15 calendar days prior to
the date on which the final hearing is to be held. The final plat
shall not be signed until the drainage plans are approved by the Village
Engineer. The plans shall be prepared on Mylar sheets 24 inches by
36 inches in size. Overall plans may be scaled at one inch equals
20 feet or one inch equals 100 feet, or any convenient scale within
this range. Overall location diagrams shall be provided on all plans.
Profiles shall be scaled at one inch equals four feet vertical and
one inch equals 40 feet horizontal. All plans shall be drawn in ink.
Title boxes showing subdivision name, owner, design engineer, scale,
and dates of preparation, submission, revision and approval shall
be provided. Stormwater design calculation sheets must be submitted
along with the plans and profiles. Overall plans covering the entire
subdivision area must be provided. No section of an overall subdivision
will be permitted to commence construction unless the performance
bond includes provision for adequate disposal of the stormwater runoff
from that section, even if this requires the immediate construction
of some facilities which lie beyond the limits of the section under
consideration. The plan shall indicate the following: storm sewer
sizes, gradients, invert elevations and structures; manholes numbered
in accordance with the design calculations, their type and invert
elevation; catch basins, their type, the limits of their contributory
watershed area and the area of the contributory watershed area in
acres; valley gutters; stationing of road center lines at one-hundred-foot
intervals and changes in grade and at catch basins or manholes; special
structures; bulkheads and headwalls; recharge basins, including a
separate detail of the basin scaled at one inch equals 40 feet, showing
all corner grades, critical intermediate exterior grades, headwalls,
sluices, bottom elevations, water level limit lines, manholes, pipe,
fencing, gates and other pertinent data. The profiles must show all
street names, all existing and proposed grades, intersecting streets,
map lines or section lines, vertical curve data, stationing of all
streets, structures, changes in grade and actual low points, all stormwater
drains, structures and their lengths, types, invert elevations and
gradients, and other underground utilities which will be within three
feet of the proposed storm drains.
The drainage plans submitted with the preliminary
map need not include all of the details required for the final drainage
plan, but consideration should be given to all of the final requirements
at the time the preliminary map is submitted, so as to avoid or minimize
changes in recharge basin areas and cuts within the beds of the streets.
The preliminary map should include contours covering the entire site
and for a distance of 200 feet beyond the site in all directions,
at two-foot intervals, and the widths of any existing streets which
abut or form a part of the subdivision. All plans shall be in the
United States Coast and Geodetic Survey datum, and the plans shall
so state this. The plan shall also contain a notation that all work
will be done in accordance with the current standards, details, specifications
and requirements of the Village of Lake Grove. The existence of streets,
private rights-of-way, utility easements, drainage structures, other
utility structures, marshes, streams, ponds and lakes, municipal facilities,
such as sewage treatment plant or pumping stations, or wells and all
available information pertaining thereto shall be included on all
preliminary plans, together with indications that these features and
facilities have been taken into consideration during the preparation
of the preliminary plan.
