Prior to an action by the Planning Board approving
a plat, the applicant shall be required to complete, in accordance
with the Planning Board's decision and to the satisfaction of the
appropriate Village departments, all the street and other improvements
specified in the action approving said plat or, as an alternative,
to file with the Village Board a bond in an amount estimated by the
Planning Board to secure to the Village the satisfactory construction
and installation of the incomplete portion of the required improvements.
All required improvements shall be made by the applicant at his expense,
without reimbursement by the Village.
Performance bonds shall comply with the requirements
of § 7-730 of the Village Law and shall be satisfactory
to the Village Board as to form, sufficiency and manner of execution.
A period of one year, or such other period as the Planning Board may
determine appropriate, within which required improvements must be
completed shall be specified by the Planning Board and expressed in
the bond. The bond shall also provide that an amount determined adequate
by the Planning Board shall be retained for a period of one year after
the date of completion of the required improvements to assure their
satisfactory condition.
A.
Monuments. Monuments shall be placed at all block
corners, angle points, points of curvature in streets and points of
tangency or horizontal curves and at intermediate points as required
by The Village Engineer; however, in no case shall there be less than
four permanent monuments per block. At least one monument in each
subdivision shall be related to the USGS system and shall bear the
true elevation above sea level. In addition, markers shall be placed
at all points where street lines intersect the plat boundary and at
all lot corners. The monuments and markers shall be of such material,
size and length as may be approved by the Village Engineer.
B.
Water and sewerage facilities. Facilities for water
and sewerage shall be provided in each new subdivision in accordance
with the requirements of the appropriate agency having jurisdiction
over the planning and installation of these in the area of the subdivision;
however, the following minimum requirements of the Village shall be
met.
(1)
Central water supply systems shall be designed with
adequate pressures, mains and fire hydrants to meet Association of
Fire Underwriters' specifications for a Class C protected area.
(2)
All water mains shall be at least six inches in diameter.
(3)
Sanitary sewers shall not be used for stormwater drainage.
(4)
Central sewerage systems shall provide a four-inch
minimum size connection to each lot.
C.
Storm drainage facilities. Storm drainage facilities planned in accordance with § 198-23 of Article IV shall provide a clear and protected channel, fully adequate to handle runoff from a five-year storm, and shall be designed so that heavy runoffs which exceed the capacity of the channels can be handled with the least possible damage to improvements and structures. The rational method shall ordinarily be used in computing runoff, unless the Village Engineer directs otherwise; however, the following minimum requirements shall be met:
(1)
Storm sewers shall have a minimum diameter of 12 inches
and a minimum grade of 0.5%.
(2)
Manholes shall not be more than 300 feet apart where
pipe sizes of 24 inches or less are used, and not more than 540 feet
apart where larger sizes are installed.
(3)
Special sections of 10 to 15 feet radii shall be installed
where abrupt changes are made in alignment.
D.
Street and other improvements.
(1)
Streets shall be graded and improved with pavement,
street signs, sidewalks, street lighting standards, curbs, gutters,
trees, water mains, sanitary sewers, storm drains and fire hydrants,
except where the Planning Board may waive, subject to appropriate
conditions, such improvements as it considers are not requisite in
the interest of public health, safety and general welfare.
(2)
Underground utilities, including cable television,
required by the Planning Board shall be placed between the paved roadway
and street line to simplify location and repair of the lines, and
the subdivider shall install underground service connections to the
property line of each lot before the street is paved.
(3)
Grading and improvements shall conform to the Village
Minimum Road Specifications and shall be approved as to design and
specifications of the Village Board.
The Village may employ an inspector to act as
agent of the Planning Board, for the purposes of assuring the satisfactory
completion of improvements required by the Planning Board, and shall
determine an amount sufficient to defray costs of inspection. The
applicant shall pay the Village costs before the final plat is signed
for filing. If the Planning Board or its agent finds, upon inspection,
that any of the required improvements have not been constructed in
accordance with the approved drawings, the applicant and the bonding
company will be severally and jointly liable for the costs of completing
said improvements according to specifications.
The Planning Board may accept assurance from
each public utility company whose facilities are proposed to be installed.
Such assurance shall be in writing, addressed to the Board, stating
that such public utility company will make the installations necessary
for the furnishing of its services within a specified time, in accordance
with the approved plat.
