A.
Stormwater management.
(2)
Subdivision stormwater system design shall also be in compliance
with all NYSDEC Phase II stormwater regulation requirements except
where Town requirements are more restrictive.
(3)
Detention/retention basins shall be designed to contain the one-year,
ten-year, twenty-five-year, fifty-year and one-hundred-year twenty-four-hour
design storms for post-development peak rates of runoff while restricting
the outflow to a rate equal to the one-year, ten-year, twenty-five-year,
fifty-five-year and one-hundred-year twenty-four-hour design storms
for pre-development peak rates of runoff, respectively. The retention
or detention pond shall also include an auxiliary emergency spillway
to direct stormwater to a positive outlet in the event of an overflow.
B.
Sanitary sewer remediation.
(1)
Sanitary sewer infiltration/inflow (I/I) removal (remediation) is
required for all projects consisting of five sublots or more, as per
the Erie County Division of Sewerage Management requirements.
(2)
All remediation shall be performed within a Town of Orchard Park
sewer district.
(3)
The remedial work must be completed prior to the project's final
acceptance and dedication of the subdivision plot.
C.
Pumping stations.
(1)
Sewage pumping stations for subdivisions are discouraged.
(2)
New sewage pumping stations are only permitted where there is no
alternative available and there are sufficient units (minimum of 50
single-family homes or 70 multiunit developments) to justify the associated
operating expense.
(3)
The design engineer shall demonstrate (with topographical information
for the area surrounding the proposed development along with existing
sewer facilities information) that there is no alternative to a pumping
station and that a proposed pumping station location can serve the
entire tributary area. Unavailability of easements is not a sufficient
justification for a pumping station.
(4)
Any pumping station proposed shall be designed such that all tributary
areas within the district will be able to access and utilize the pumping
station in the future. This may mean that the wet well, force main
and electrical service have to be sized larger than what is immediately
needed for the subdivision plan. Pumps designed for less than the
ultimate tributary area will be reviewed on a case-by-case basis.
Access easements for future sewer lines from outside the proposed
development shall also be provided under such circumstances.
(5)
In certain situations, a proposed development may be tributary to
an existing sewage pumping station which has insufficient capacity
to accept additional flow. In such cases, plans to bring the existing
pumping station into conformity with the Town standards will be required
before the development plans are approved. Specific plans and specifications
for necessary renovations shall be subject to a case-by-case review
and approval by the Town.
D.
Signage. Traffic control and street identification signage and other
signage as deemed necessary (no parking, etc.) is to be provided prior
to the dedication of the development, as required.
E.
Street lighting. Streetlighting is to be installed as per the latest
Town specifications prior to the final dedication of the subdivision.
F.
Pedestrian access.
No development of land, including excavation,
clearing of brush or laying out of roads, shall be undertaken without
fully complying with the requirements of this Part 1.
The Planning Board may waive any or all regulations
contained herein where, in its judgment of the special circumstances
presented by a particular case, the regulation(s) is not required
in the interest of public health, safety and general welfare.[1]
