1. Appropriate sections from the Borough's Subdivision and Land Development
Ordinance, and other applicable local ordinances, shall be followed
in preparing the SWM site plans. In instances where the Borough lacks
Subdivision and Land Development regulations, the content of SWM site
plans shall follow the Allegheny County Subdivision and Land Development
Ordinance.
2. 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 part, 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.
3. 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 3I below.
B. The following signature block for the Borough:
"The municipal engineer, on this date September 19, 2018, has
reviewed and hereby certifies that the SWM site plan meets all design
standards and criteria of the Municipal Ordinance No. 2018-05 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
Manual. 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 §
23-301.
(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)
The 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.
[Ord. 505, 2/19/2004, § 402; as amended by Ord. No. 2018-05, 11/14/2018]
Up to five copies of the SWM site plan shall be submitted as
follows:
1. Two copies to the Borough.
2. One copy to the municipal engineer (when applicable).
3. One copy to the Allegheny County Conservation District (when requested
by the District).
4. One copy to the Allegheny County Sanitary Authority (in areas with

[Ord. 505, 2/19/2004, § 403; as amended by Ord. No. 2018-05, 11/14/2018]
1. The Borough has designated the municipal engineer as the designated
plan reviewer of SWM site plans for the Borough, and shall be understood
to be the reviewer where indicated as the Borough within this chapter.
2. SWM site plans shall be reviewed by the Borough for consistency with
the provisions of this chapter.
3. The Borough shall notify the applicant in writing within 45 days
whether the SWM site plan is approved or disapproved or requires additional
documentation. If the SWM site plan involves a subdivision and land
development plan, the notification shall occur within the time period
allowed by the Municipalities 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 Borough.
4. For any SWM site plan that proposes to use any BMPs other than green
infrastructure and LID practices to achieve the volume and rate controls
required under this chapter, the Borough will not approve the SWM
site plan unless it determines that green infrastructure and LID practices
are not practicable.
5. If the Borough disapproves the SWM site plan, the Borough will state
the reasons for the disapproval in writing. The Borough also may approve
the SWM site plan with conditions and, if so, shall provide the acceptable
conditions for approval in writing.
6. The applicable review fee, in accord with Part 6, must accompany
a resubmission of a disapproved SWM site plan.
[Ord. 505, 2/19/2004, § 404; as amended by Ord. No. 2018-05, 11/14/2018]
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 part.
[Ord. 505, 2/19/2004, § 405; as amended by Ord. No. 2018-05, 11/14/2018]
A disapproved SWM site plan may be resubmitted, with the revisions
addressing the Borough's concerns, to the Borough in accordance with
this part. The applicable review fee, in accord with Part 6, must
accompany a resubmission of a disapproved SWM site plan.
[Ord. 505, 2/19/2004, § 406; as amended by Ord. No. 2018-05, 11/14/2018]
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 §
23-407 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 §
23-405 of this chapter.
[Ord. 505, 2/19/2004, § 407; as amended by Ord. No. 2018-05, 11/14/2018]
1. The developer shall be responsible for providing record drawings
of all SWM BMPs included in the approved SWM site plan. The record
drawings and an explanation of any discrepancies with the construction
plans shall be submitted to the Borough.
2. The record drawing submission shall include a certification of completion
signed by a qualified professional verifying that all permanent SWM
BMPs have been constructed according to the approved plans and specifications.
The latitude and longitude coordinates for all permanent SWM BMPs
must also be submitted, at the central location of the BMPs, if any
licensed qualified professionals contributed to the construction plans,
then a licensed qualified professional must sign the completion certificate.
3. The Borough may conduct inspections during construction as it deems
appropriate. If inspections performed by the Borough reveal deficiencies
from the submitted and approved SWM site plan, the Borough may request
corrective actions. Any corrective action shall be at the cost of
the stormwater facility owner.
4. After receipt of the completion certification by the Borough, the
Borough may conduct a final inspection.
