The Westmoreland County Integrated Water Resources Plan provides
an online decision making tool to assist developers, designers, property
owners in addressing all water resources during development and redevelopment
and should be consulted. Refer to www.paiwrp.com for the decision-making
tool and www.westmorelandstormwater.org.
2.
Applicants should refer to the Westmoreland County Integrated Water
Resources Plan (IWRP) located at www.westmorelandstormwater.org, for
mapping of impaired streams, riparian buffers and pollutant loading
to determine appropriate BMPs to address sources of impairments.
3.
Before submitting the stormwater management plan, and any other plan
required by a reviewing agency, applicants are urged to consult with
Manor Borough, Westmoreland County Department of Planning and Development
and Westmoreland Conservation District, and PennDOT where applicable,
on the requirements for safely managing the development site in a
manner consistent with Manor Borough ordinances, applicable watershed
stormwater management plan and federal and state requirements. These
agencies may also be helpful in providing necessary data for the stormwater
management plan.
4.
Applicants are encouraged to submit a sketch plan with a narrative
description of the proposed stormwater management controls for general
guidance and discussion with the Borough and other agencies.
5.
The pre-application phase is not mandatory; any review comments provided
by Manor Borough or other agencies are advisory only and do not constitute
any legally binding action on the part of Manor Borough or any county
agency.
[Ord. No. 589-21-01, 6/16/2021]
1.
Submission of Plans. Stormwater management plan application shall
be submitted with the preliminary and final subdivision/land development
applications or if no subdivision or land development is involved,
then with the application for development. Copies of the SWM site
plan shall be submitted to the following agencies as determined by
Manor Borough:
A.
Two copies to Manor Borough. One copy to other affected municipalities.
B.
One copy to the Borough Engineer.
C.
One copy to the Westmoreland Conservation District (when applicable).
D.
One copy to the local sanitary authority (when applicable).
E.
One copy to the Westmoreland County Department of Planning and Development
(if applicable).
F.
One copy to the Westmoreland County Department of Public Safety/local
emergency management coordinator (when applicable).
G.

2.
Notification of Affected Municipalities. Manor Borough shall notify
municipalities upstream and downstream of the development site which
may be affected by the stormwater runoff and proposed controls for
the site. Copies of the plans will be made available to the affected
municipalities upon request. Comments received from any affected municipalities
will be considered by Manor Borough engineer and county agencies in
their reviews.
3.
Review by Manor Borough Engineer and Westmoreland Conservation District
(WCD).
A.
Stormwater management plans shall be reviewed by the Manor Borough
Engineer and WCD. BMPs shall be shown on all stormwater management
plans and erosion and sedimentation control plans, as applicable.
At its discretion, Manor Borough and/or WCD may also engage other
specialists in hydrology or hydraulics to assist with the stormwater
management plan review. The WCD will review the plan for general compliance
with the watershed plan standards and criteria and watershed-wide
impacts and, where appropriate, may consult with adjacent municipalities
and counties for their comments. If the WCD review identifies the
improper application of the watershed standards and criteria or the
possibility of harmful impacts downstream from the development site's
proposed stormwater management system, the applicant and Manor Borough
engineer will be notified so that the necessary modifications can
be made to promote safe stormwater management.
B.
Manor Borough and the WCD shall notify the applicant in writing within
45 days whether the SWM site plan is approved or disapproved. If the
SWM site plan involves a subdivision and land development plan, the
notification shall occur within 90 days, unless the applicant is notified
that a longer notification period is provided by other statute regulation
or ordinance. If modifications are required, the review period may
be extended by Manor Borough and the WCD, in order for the applicant
to address inadequacies.
4.
A disapproved stormwater management plan may be resubmitted, with
the revisions addressing Manor Borough's and/or WCD's concerns,
to Manor Borough and the WCD in accordance with this article.
5.
Manor Borough Engineer Review. The Borough Engineer shall approve
or disapprove the stormwater management plan based on the requirements
of Manor Borough ordinances, the standards and criteria of the watershed
plan, applicable state and federal requirements and good engineering
practice. The Manor Borough Engineer shall submit a written report,
along with supporting documentation, stating the reasons for approval
or disapproval.
6.
Status of the Engineer's Determination. The approval/disapproval
of the site's stormwater management plan by the Borough Engineer
shall be submitted to the Manor Borough Council for final action.
Final approval of the plan rests with the Manor Borough.
7.
Permits Required From Other Governmental Agencies. Where the proposed
development requires a permit from the Pennsylvania DEP, PennDOT,
or an erosion/sedimentation permit or Chapter 105 permit from the
Westmoreland Conservation District, then final stormwater management
plan approval shall be conditional upon receipt of such permits. However,
no building permit shall be issued, nor construction or development
started, until the permits are received and copies filed with the
Manor Borough.
[Ord. No. 589-21-01, 6/16/2021]
1.
Upon final stormwater management plan approval and receipt of all
necessary permits, financial guarantees and agreements, the applicant
may commence to install or implement the approved stormwater management
plan, BMPs plan or erosion and sedimentation plan controls.
2.
If site development or building construction does not begin within
two years of the date of final approval of the stormwater management
plan, then before doing so, the applicant shall re-submit the stormwater
management plan, BMPs plan or erosion or sedimentation plan to verify
that no condition has changed on the property, adjacent to the site
or within the watershed that would affect the feasibility or effectiveness
of the previously approved stormwater management controls. Further,
if for any reason development activities are suspended for two years
or more, then the same requirement for re-submission of the stormwater
management plan shall apply.
[Ord. No. 589-21-01, 6/16/2021]
1.
If the request for a plan modification is initiated before construction
begins, the stormwater management plan must be resubmitted and reviewed
according to the procedures, contained in this chapter.
A.
If the request for a plan modification is initiated after construction
is underway, the Manor Borough Engineer and/or the WCD shall have
the authority to approve or disapprove the modification based on field
conditions; provided:
(1)
The requested changes in stormwater controls do not result in
any modifications to other approved Borough land use/development requirements
(e.g., building setbacks, yards, etc.).
(2)
The performance standards in this chapter are met. Notification
of the Engineer's and/or WCD's action shall be sent to Manor
Borough Council which may issue a stay of the plan modification within
five days and require the permittee to resubmit the plan modification
for full stormwater management plan review in accordance with this
chapter.
B.
It shall be unlawful to, and no person shall, alter, replace, modify,
landscape or remove, or otherwise adversely affect, any permanent
stormwater management facilities, BMP controls, or any area within
a stormwater easement or dedicated or designated area for stormwater
facilities and BMPs required by an approved stormwater management
plan, BMP operations and maintenance plan, or to allow the property
to remain in a condition which does not conform to an approved stormwater
management plan, BMP operations and maintenance plan, unless an exception
is granted in writing by the Borough and/or approval is secured from
all relevant agencies of the commonwealth.
