this requirement.
(3)
Runoff from a proposed parking facility or building would increase
the peak runoff from the existing condition.
B.
The design criteria for the stormwater detention facility shall be
agreed upon by the Borough Engineer. Developers are encouraged to
investigate all measures to reduce and detain water, for discharge
at a delayed rate or ground water recharge. All reasonable methods
will be considered.
6.
Basins or Other Management Facilities.
A.
General Provisions.
(1)
The design of all stormwater basins must be approved by the
Borough Engineer based upon their effectiveness for achieving stormwater
control objectives, water quality enhancement, groundwater recharge,
ease of maintenance, safety considerations, and conformance to landscape
and surrounding uses and activities.

that drain into them. The phasing of their construction shall be noted
on the plan.
(3)
Where basins are required by Borough, adequate maintenance guarantees,
indemnification, insurance, and security shall be provided by the
applicant and approved by the Borough.
(4)
Where feasible, basins shall be developed jointly by abutting
landowners, or regionally by several developing landowners.
(5)
If a basin is to remain in private ownership, the applicant
shall assure proper maintenance in the form of a recorded deed restrictions,
bonds, or escrows, as approved by the Borough. The Borough has the
right to enter the lot to perform any required maintenance that has
not been performed or carried out in a timely manner by the lot owner.

freeboard for storms up to a twenty-five-year, twenty-four-hour design
storm and a one-foot freeboard for storms up to the one-hundred-year,
twenty-four-hour storm.
(2)
Emergency spillways, where considered necessary by the Borough
Engineer, shall be sized and located to permit the safe passage of
stormwater flows from a one-hundred-year storm. The maximum velocities
in vegetated spillways excavated in undisturbed soil shall be checked
based upon the velocity of peak flow in the emergency spillway during
an assumed clogged primary outlet condition. Where maximum velocities
exceed design standards contained in the Erosion and Sediment Pollution
Control Manual, suitable lining shall be provided. All emergency spillways
placed on fill materials shall be lined. Lining for emergency spillways
shall incorporate native colors and materials where possible including
mono slab revetments, grass pavers and native stone.
(3)
Inlet Structures. The invert of the inlet pipe into a basin
shall be six inches above the basin floor or lining so that the pipe
can adequately drain after rain storms. Inlets shall discharge into
areas of the basin that slope toward the outlet structure. Inlet and
outlet structures shall be located at a maximum distance from each
other in order to promote water quality benefits. The Borough Engineer
may require a rock filter or rock filled gabion for entrapping sediments
carried in stormwater if sufficient separation of inlet and outlet
structure cannot be achieved.

outlet pipes shall have an internal diameter of at least 18 inches
and a minimum grade of 1%. Anti-seep collars shall be located on all
outlet pipes. All principal outlet structures shall be built with
reinforced concrete with watertight construction joints. The developer
shall consider the use of architecturally treated concrete, stucco,
painted surface or stone facade treatment for enhancing the outlet
structure. Outlet pipes shall be constructed of reinforced concrete
with rubber gaskets in conformance with AASHTO M170, M198 and M207.
Child proof trash racks or anti-vortex devices shall be constructed
at all outlets and designed to facilitate cleaning and avoid clogging
caused by debris.
(6)
Stabilization. Prior stabilization, structures including stilling
basins, energy dissipators, and channel lining shall be constructed
at the outlets of all basins and emergency spillways. The stabilization
structures shall control water to avoid erosion, reduce velocities
of released water and direct water so that it does not interfere with
downstream activities.
(7)
Wet Basins. Existing ponds or permanent pool basins can be used
provided that they meet the following criteria:
(a)
The minimum permanent pool level shall be maintained to allow
sufficient depth throughout the year to reduce the growth of unwanted
vegetation and mosquitoes.

The pond must be of sufficient size to allow the appropriate
aquatic community needed to maintain a healthy pond ecology.
(c)
An outlet structure shall be designed to allow complete drainage
of the pond for maintenance.
(d)
The applicant shall submit wet basin planting schedule and method
for mosquito control.
|
The design of a detention facility with a permanent pool shall
include the determination of the proposed site's ability to support
a viable permanent pool. The design shall take into account for such
factors as the required rate and quality of dry weather inflow, the
quality of stormwater inflow, seasonal and longer term variations
in groundwater table, and effects of suspected pollutant loadings.
|
(8)
Basins with Gabion Dams. Gabion outlet control structures for
stormwater basins shall be filled with rocks six inches to eight inches
in diameter. Outlet flow through the gabions shall be calculated by
the following equation:

lines at corners, angle points, beginning and end of curves, and as
otherwise required by the Borough Engineer for all new and existing
streets. They shall be placed after a new street and/or lot grading
has been completed. The center line of all new streets shall be marked
with spikes (P.K. nails) and referenced to permanent monuments or
structures. Certified copies of this reference information shall be
given to both the Borough Engineer and the Borough Office. When final
lot grading has been completed and before the issuance of occupancy
permits, permanent monuments shall be set by the subdivider, developer,
or builder, at all lot corners and angle points, and at all street
intersections and intermediate points as may be required.
2.
Lot Pin Requirements. All lots upon which construction is planned shall be temporarily staked or pinned, or permanently monumented and certified to such by a registered surveyor for the owner, subdivider, builder, or developer, before issuance of a building permit. A signed certificate of compliance must be submitted with a building permit application. Temporary stakes or pins with a surveyor's ribbon attached may be acceptable on existing lots where construction of an accessory building or an addition to the primary structure is proposed, only if construction is begun within 30 days of the certificate of compliance date. Temporary stakes or pins shall remain in place until witnessed and accepted by the Borough Building Inspector. Prior to final approval of a new subdivision plan, all new lot corner markers shall be marked with a minimum 5/8 inch diameter metal pin extending at least 24 inches into the ground and at least one inch revealed above the ground surface, or an equivalent metal marker, approved by the Borough Engineer. Upon completion of construction and final grading, pins shall be replaced with permanent monuments as described in Subsection 1.
3.
Original Monuments. In situations where they may be of legal or historical
importance, the original monuments and marks must not be destroyed,
defaced, hidden, or possible confused by creating new monuments and
marks unless absolutely necessary, e.g., the originals are decayed,
destroyed, or unsafe. In some cases, to be determined by the Borough
Engineer, new monuments shall be set as a reference or witness to
the original monument to avoid disturbing the original. When in the
opinion of the Borough Engineer, the angle point falls in a location
that is not appropriate to set a concrete monument, a written request
for a waiver shall be submitted for consideration by Borough Council.
4.
Bench Marks. The Borough elevations are based on the USGS datum.
Location and elevation is available to all engineers and surveyors
upon request to the Borough Engineer's Office. All contours and
elevations shown on the plan must be based on this system.
