Appropriate sections from Chapter
197 of the Borough's Code of Ordinance, Subdivision and Land Development, and other applicable local ordinances, shall be followed in preparing the SWM site plans. The Borough shall not approve any SWM site plan that is deficient in meeting the requirements of this chapter. At its sole discretion and in accordance with this article, when a SWM site plan is found to be deficient, the Borough may either disapprove the submission and require a resubmission, or in the case of minor deficiencies, the Borough may accept submission of modifications. The following items shall be included in the SWM site plan:
A. Provisions for permanent access or maintenance easements for all physical SWM BMPs, such as ponds and infiltration structures, as necessary to implement the operation and maintenance (O&M) plan discussed in Subsection
C(9) below.
B. The following signature block for the Borough:
"(Designated plan reviewer), on this date (signature date),
has reviewed and hereby certifies that the SWM site plan meets all
design standards and criteria of the Municipal Ordinance No. 1650
except where waivers have been granted as noted on the plan. The review
is based on a survey and plan prepared by others and assumes that
all information is correct and valid as submitted."

C. The SWM site plan shall provide the following information:
(1) The overall stormwater management concept for the project.
(2) A determination of site conditions in accordance with the BMP Manual3. A detailed site evaluation shall be completed for projects
proposed in environmentally sensitive areas, such as brownfields.
(3) 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 §
190-10.
(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.
(7) Plan and profile drawings of all SWM BMPs, including drainage structures,
pipes, open channels, and swales.
(8) SWM site plan shall show the locations of existing and proposed on-lot
wastewater facilities and water supply wells, property boundaries,
existing and proposed topography, point(s) of interest, utilities,
and potential utility conflicts.
(9) 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
including type and schedule/frequency of maintenance activities, personnel
and equipment requirements, estimated annual maintenance costs, and
method of financing continuing O&M.
(10)
A justification, acceptable to the designated plan reviewer,
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 under this chapter.
(11)
A list of any permits/approvals relative to stormwater management
that will be required from other governmental agencies (e.g., an obstructions
permit from DEP) and anticipated dates of submission/receipt should
be included with the stormwater plan submission. Copies of permit
applications may be requested by the Borough where they may be helpful
for the plan review.
Up to five copies of the SWM site plan shall be submitted as
follows:
A. Two copies to the Borough.
B. One copy to the municipal engineer (when applicable).
C. One copy to the Allegheny County Conservation District (when requested
by the District).
D. One copy to the Allegheny County Sanitary Authority (in areas with
combined sewer systems).
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 designated plan reviewer, 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 Borough's concerns, to the Borough in accordance with this chapter. The applicable review fee, in accord with Article
V, must accompany a resubmission of a disapproved SWM site plan.
The Borough'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 Borough 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 Borough signs the approval for an SWM site plan. If an approved SWM site plan is not completed according to §
190-21 within the term of validity, then the Borough may consider the SWM site plan disapproved and may revoke any and all permits. SWM site plans that are considered disapproved by the Borough shall be resubmitted in accordance with §
190-19 of this chapter.
