ARTICLE V Stormwater Management Plan Submission and Review Procedures.
§501. Preapplication Phase.
- 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. - Applicants should refer to the Westmoreland County Integrated Water Resources Plan
(JWRP) located at www.westmorelandstormwater.org, for mapping of impaired streams,
riparian buffers and pollutant loading to determine appropriate BMPs to address sources
of impairments. - Before submitting the storm water management plan, and any other plan required by a
reviewing agency, applicants are urged to consult with the municipality, 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 the municipality 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. - Applicants are encouraged to submit a sketch plan with a narrative description of the
proposed storm water management controls for general guidance and discussion with the
municipality and other agencies. - The pre-application phase is not mandatory; any review comments provided by the
municipality or other agencies are advisory only and do not constitute any legally binding
action on the part of the municipality or any County agency.
§502. Stormwater Management Plan Submission and Review.
- 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 Bolivar Borough:
- Two copies to the municipality(ies).
- One copy to the municipal engineer (when applicable).
- One copy to the Westmoreland Conservation District (when applicable).
- One copy to the local Sanitary Authority (when applicable).
- One copy to the Westmoreland County Department of Planning andDevelopment. (if applicable)
- One copy to the Westmoreland County Department of Public Safety / local
emergency management coordinator (when applicable) - One copy to DEP (when applicable)
- Notification oj Affected Municipalities. The municipality 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 the Bolivar Borough engineer and County
agencies in their reviews. - Review by Bolivar Borough Engineer and Westmoreland Conservation District (WCD).
Stormwater management plans shall be reviewed by the municipality engineer and
WCD. HMPs shall be shown on all stormwater management plans and erosion and
sedimentation control plans, as applicable. At its discretion, the municipality 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
municipality engineer will be notified so that the necessary modifications can be made
to promote safe stormwater management.
The municipality 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 the municipality and the WCD, in order for the applicant to address
inadequaci es.
- A disapproved stormwater management plan may be resubmitted, with the revisions
addressing the Municipality's and/or WCD's concerns, to the Municipality and the
WCD in accordance with this article. - Bolivar Borough Engineer Review. The municipality engineer shall approve or
disapprove the stormwater management plan based on the requirements of the
[Municipality] ordinances, the standards and criteria of the watershed plan, applicable
State and Federal requirements and good engineering practice. The Bolivar Borough
Engineer shall submit a written report, along with supporting documentation, stating the
reasons for approval or disapproval. - Status oj the Engineer's Determination. The approval/disapproval of the site's
stormwater management plan by the municipality engineer shall be submitted to the the
Bolivar Borough Council for final action. Final approval of the plan rests with the
municipality.
- 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 municipality. - Reviews by the Municipality and WCD may be subject to fees as outlined in Article vn
section 706 of this Ordinance.
§503. Status of Stormwater Management Plan after Approval.
- 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. - If site development or building construction does not begin within [2] years of the date
offinal approval of the stormwatermanagement 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 [2] years or more, then the same requirement
for re-submission of the stormwater management plan shall apply.
§504. Modification of Stormwater Management Plan.
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 ordinance.
A. If the request for a plan modification is initiated after construction is underway, the Bolivar
Borough Engineer and / or the WCD shall have the authority to approve or disapprove the
modification based on field conditions; provided:
- The requested changes in stormwater controls do not result in any modifications to
other approved municipality land use/development requirements (e.g., building
setbacks, yards, etc.). - The performance standards in this Ordinance are met. Notification of the
Engineer's and / or weD's action shall be sent to the Bolivar Borough Council
which may issue a stay of the plan modification within 5 days and require the
permittee to re-submit the plan modification for full stormwater management plan
review in accordance with this ordinance.
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 storm water 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
