to Section 420 of the Act of June 1, 1945 (P.O. 1242, No. 428), known
as the 'State Highway Law,' before access to a state highway is permitted.
Access to the state highway shall be as authorized by a highway occupancy
permit, and the Council's approval of this plan in no way implies
that such a permit can be acquired."
V.
A complete landscape plan showing the location, size and type of
all plan material required by provisions of this chapter or any other
applicable Borough regulations, including but not limited to all vegetated
stormwater BMPs. The landscape plan should be provided on separate
sheets and must include the signature and seal of the registered landscape
architect responsible for preparation of the plan. Native or naturalized/noninvasive
vegetation suitable to the soil and hydrologic conditions of the development
site shall be used unless otherwise specified in the BMP Manual. The
limit of existing, native vegetation to remain shall be delineated
on the plan along with proposed construction protection measures.
W.
A detailed schedule of inspections during construction, as generally
outlined as follows, which is tailored for the site under consideration:
(1)
The Borough shall inspect all phases of the installation of
any temporary or permanent stormwater management facilities during
construction. The developer shall pay the cost of any such inspection.
The developer shall provide at least 48 hours' notice prior to the
start of construction of any improvements that are subject to inspection.
All inspections of completed items shall be requested, in writing,
as least 72 hours in advance of the inspection time and date.
(2)
It is generally required that the following phases of site construction
have mandatory inspection. This general list of phases may be amended
by mutual agreement of the Borough and developer when the site requires
special construction procedures. The inspection schedule must be shown
on the approved stormwater management site plan.
(3)
General site construction.
(a)
Upon completion of preliminary site preparation, including the
stripping of the vegetation, stockpiling of topsoil and construction
of temporary erosion and sedimentation control devices.
(b)
Upon completion of rough grading, but prior to placing topsoil,
permanent drainage, or other site development improvements and ground
covers.
(c)
During the construction of permanent stormwater management and
BMP facilities.
(d)
Upon the final completion of permanent stormwater management
and BMP facilities, including the establishment of ground covers and
plantings.
(4)
In addition to the above-outlined observations, additional observations
will be made at the request of the developer for reduction of financial
securities. Random observations should be made at the frequency desired
by the Borough. At the time of any of the above-listed observations,
all ongoing construction (i.e., storm drainage, grading, placement
of impervious surfaces, changes in ground cover, erosion control,
etc.) should also be checked for compliance with the approved plans
and the finding reported. Since the above inspections are mandatory,
it is recommended that requests for reduction of financial security
be submitted to coincide with the above inspections.

management facilities prior to occupancy or the release of financial
security.

to be used for structural SWM facilities. The narrative shall include
a description of any treatment trains and how the facilities are meant
to function with each other to manage stormwater runoff.

The effect of the project (in terms of runoff volumes, water quality
and peak flows) on adjacent properties and on any existing municipal
stormwater management facilities that may receive runoff from the
development site.

Chapter 102, shall be provided to the municipality prior to unconditional
final plan approval.
C.
For any activities that require a DEP joint permit application and are regulated under Chapter 105 or Chapter 106,[1] require a PennDOT highway occupancy permit, or require
any other permit under applicable state or federal regulations, the
permit(s) shall be part of the SWM site plan and must be obtained
prior to unconditional final plan approval.
