The drainage plan shall include detailed plans
of all stormwater drainage facilities, street profiles and other utilities
which may be required by the Planning Board. These plans are considered
to be an integral part of the final plat submission and are, therefore,
the basis for the performance bond and inspection fee.
A. It is intended that all drainage problems within the
limits of the development or subdivision area will be completely resolved
by the design as approved by the Planning Board before any work is
started. However, in the event that an error on the part of the designing
engineer, either of design or judgment, becomes apparent during the
progress of the work or after completion of the work, the Planning
Board reserves the right to stop the work and/or order the necessary
changes to correct the situation. The Planning Board shall be held
blameless for any change so made.
B. In order to achieve better comprehensive drainage
design, subdivision storm drainage systems shall, upon recommendation
of the Planning Board, be partially or completely integrated with
the area storm drainage system. In the following cases the developer
may be required to pay to the village a drainage contribution towards
the cost of such area storm drainage system:
(1) As to subdivisions lying within drainage areas for
which the village has designed storm drainage collection and disposal
systems, the drainage contribution toward the cost of participating
in the village drain system shall be borne by the developer on the
basis of his proportional share of the drainage contributed to the
total system and shall be computed by the Village Engineer.
(2) In a subdivision which, because of the small area
being drained, would result in a disproportionately high cost of maintenance
for the system, the developer shall participate in the cost of the
future drainage systems on the basis of the alternate cost to him
of a drainage system if constructed within the subdivision.
Where leaching wells have been approved by the
Village Engineer for the drainage of a particular area, the following
minimum specifications shall be complied with:
A. Each drainage leaching well shall consist of three
eight-foot-in-diameter precast sections and 4 1/2 feet deep of
precast sections and one precast dome section or flat slab with cast-iron
manhole frame and heavy-duty cover set flush with the grade and designed
to accommodate normal traffic loadings as established by the Village
Engineer upon reference to Suffolk County, New York State AASHTO standards.
[Amended 2-4-1999 by L.L. No. 1-1999]
B. Leaching wells shall be set on right-of-way, off the
pavement, and a combination curb and gutter outlet catch basin shall
be provided at the edge of the pavement with a heavy-duty drainage
cover designed to accommodate normal traffic loadings as established
by the Village Engineer upon reference to Suffolk County, New York
State AASHTO standards, and connected to the leaching well with reinforced
concrete pipe of sufficient size.
[Amended 2-4-1999 by L.L. No. 1-1999]
C. Each leaching well shall be surrounded by three-fourths-inch
broken stone or washed gravel stone for a distance of one foot before
backfilling.
