in meeting the requirements of this chapter. At its sole discretion

The SWM site plan shall provide the following information:
(1)
The overall stormwater management concept for the project.

Stormwater runoff design computations and documentation as specified in this chapter, or as otherwise necessary to demonstrate that the maximum practicable measures have been taken to meet the requirements of this chapter, including the recommendations and general requirements in § 296-11.
(4)
Expected project time schedule.
(5)
A soil erosion and sediment control plan, where applicable, as prepared
for and submitted to the approval authority.
(6)
The effect of the project (in terms of runoff volumes, water quality,
and peak flows) on surrounding properties and aquatic features and
on any existing stormwater conveyance system that may be affected
by the project.

SWM site plan shall show the locations of existing and proposed on-lot
wastewater facilities and water supply wells.

The SWM site plan shall include an O&M plan for all existing
and proposed physical stormwater management facilities. This plan
shall address long-term ownership and responsibilities for O&M
as well as schedules and costs for O&M activities.
(10)
A justification must be included in the SWM site plan if BMPs
other than green infrastructure methods and LID practices are proposed
to achieve the volume, rate, and water quality controls required under
this chapter, the Township will not approve the SWM site plan unless
it determines that green infrastructure and LID practices are not
practicable.
A.
The SWM site plan shall be submitted by the developer to the Township
as part of the preliminary plan submission for the subdivision or
land development.
B.
Five copies of the SWM site plan shall be submitted as follows for regulated activities specified in § 296-5D(1) and (2):

impervious cover shall be submitted by the developer (possibly through
the Township) to the Lehigh Valley Planning Commission as part of
the preliminary plan submission. The Lehigh Valley Planning Commission
will conduct an advisory review of the SWM site plan for consistency
with the Little Lehigh Creek Watershed, Coplay Creek Watershed, or
the Jordan Creek Watershed Stormwater Management Plan. The LVPC will
not review details of the erosion and sedimentation plan or the BMP
operations and maintenance plan.
(1)
Two copies of SWM site plan shall be submitted.
(2)
The Lehigh Valley Planning Commission will provide written comments
to the developer and the Township, within a time frame consistent
with established procedures under the Municipalities Planning Code,
as to whether the SWM site plan has been found to be consistent with
the stormwater management plan.
E.
(1)
The SWM site plan shall be submitted by the developer to the Lehigh
Valley Planning Commission for coordination with the DEP permit application
process under Chapter 105 (Dam Safety and Waterway Management) or
Chapter 106 (Floodplain Management) of DEP's rules and regulations.
(2)
One copy of SWM site plan shall be submitted.
A.
SWM site plans, including the BMP operations and maintenance plans shall be reviewed by the Township Engineer for consistency with the provisions of this chapter and any permits issued by DEP.

B.
The Township shall notify the applicant in writing within 45 days
whether the SWM site plan, including the BMP operations and maintenance
plan is approved or disapproved. If the SWM site plan involves a Subdivision
and Land Development Plan, the notification shall occur within the
time period allowed by the Township's Planning Code (90 days).
If a longer notification period is provided by other statute, regulation,
or ordinance, the applicant will be so notified by the Township.

green infrastructure and LID practices to achieve the volume and rate
controls required under this chapter, The Township will not approve
the site plan unless it determines that green infrastructure and LID
practices are not required.
D.
If the Township disapproves the SWM site plan, the Township will
state the reasons for the disapproval in writing. The Township also
may approve the SWM site plan with conditions and, if so, shall provide
the acceptable conditions for approval in writing.
E.
The Township may require an as-built survey of all stormwater BMPs
and an explanation of any discrepancies with the drainage plan.
A modification to a submitted SWM site plan that involves a
change in SWM BMPs or techniques, or that involves the relocation
or redesign of SWM BMPs, or that is necessary because soil or other
conditions are not as stated on the SWM site plan as determined by
the Township Engineer shall require a resubmission of the modified
SWM site plan in accordance with this chapter.
A disapproved SWM site plan may be resubmitted, with the revisions
addressing the Township's concerns, to the Township in accordance

The Township's approval of an SWM site plan authorizes the regulated activities contained in the SWM site plan for a maximum term of validity of five years following the date of approval. The Township may specify a term of validity shorter than five years in the approval for any specific SWM site plan. Terms of validity shall commence on the date the Township signs the approval for an SWM site plan. If an approved SWM site plan is not completed according to § 296-35 within the term of validity, then the Township may consider the SWM site plan disapproved and may revoke any and all permits. SWM site plans that are considered disapproved by the municipality shall be resubmitted in accordance with § 296-34 of this chapter.

licensed qualified professionals contributed to the construction plans,
then a licensed qualified professional must sign the completion certificate.
