A.
During the preapplication conference, applicants are encouraged to
consult with the Borough Engineer, the Allegheny County Planning Department,
and the county conservation district on the applicable regulations
and techniques for safely managing stormwater runoff from the development
site in a manner consistent with the Borough ordinances. These agencies
may be helpful in providing the data that is necessary for preparing
the stormwater management plan or the development site.
B.
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.
C.
The preapplication phase is not mandatory, and any review comments
provided by Borough or other agencies are advisory only and do not
constitute any binding action on the part of the Borough or any other
agency.
A.
Preliminary and final plans required. Stormwater management plans,
in accordance with the requirements of this Part 2, will be submitted
with the preliminary and final subdivision or land development plan
application to the Borough Secretary, together with the appropriate
fees.
B.
Review by Borough Engineer and Conservation District. Preliminary
and final stormwater management plans will be reviewed by the Borough
Engineer.
C.
Notification of affected municipalities. If, during the review of
the proposed stormwater management plan, the Borough determines that
properties in adjacent municipalities may be affected by the stormwater
runoff and proposed management system for the site, the applicant
will notify the affected municipality(ies) and provide an opportunity
to submit comments as part of the preliminary or final plan reviews.
Copies of the plans will be made available to the municipalities upon
request. Comments received will be submitted to the Planning Commission
and Borough Council.
D.
Borough Engineer's review. The Borough Engineer shall provide
a recommendation to approve or disapprove the preliminary and final
stormwater management plan based on the requirements of the Borough's
ordinances, the standards and criteria of the watershed plan and good
engineering practice. The Engineer shall submit a written report,
along with supporting documentation, to the Borough Planning Commission
for its consideration as part of the overall subdivision or land development
plan review. In the cases where the Borough will be responsible for
the maintenance of the stormwater management facility, the Borough
Engineer shall also prepare a recommended maintenance program for
review and approval by Council.
E.
Approval of stormwater plan required for subdivision and land development
approval. No preliminary or final approval shall be granted for the
overall subdivision or land development application until a stormwater
management plan for the site has been approved.
F.
Permits required from other governmental agencies. Where the subdivision
or land development application requires a water obstruction or erosion/sedimentation
permit, then final subdivision or land development plan approval shall
be conditional upon receipt of such permits. However, no building
permit shall be issued, or construction started, until the permits
are received and copies filed with the Borough. Approval from Allegheny
county conservation district or the Pennsylvania Department of Environmental
Protection for Soil and Erosion is required prior to construction.
G.
County planning review.
(1)
The Borough shall forward a copy of the stormwater plan, along with
all runoff calculations, shall be forwarded to the Allegheny County
Planning Department. A report of the findings will be returned to
the Borough within 30 days.
(2)
If the Allegheny County Planning Department determines that the plan
fails to comply with the watershed standards and criteria or that
a possibility exists for harmful downstream impacts from the development
site, the applicant will be advised so that proposed stormwater management
controls can be modified. The Borough Engineer shall not recommend
approval of the development site's stormwater management plan
until it receives a positive review from the County Planning Department.
H.
Status of the Engineer's determination. The recommendation of
approval/disapproval of the site's stormwater management plan
by the Borough Engineer shall be considered final. The governing body
shall not reverse the engineer's determination by approval or
disapproving the site's stormwater management plan or any specific
control measure in contradiction to the engineer's action. The
governing body may request modifications or alternative approaches
to the stormwater management controls, provided that these are agreed
to by the Borough Engineer and the applicant's engineer.
Upon recording of the final plat, the applicant may start to
install or implement the approved stormwater management controls,
subject to the provisions of the above. If site development or building
construction does not begin within two years of the date of final
approval of the subdivision or land development plan, then before
doing so, the applicant shall resubmit the stormwater management plans
to verify that no condition has changed 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 resubmission of the stormwater management plan shall apply. The
terms of these subsequent reviews shall be subject to the provisions
of this Part 2 and any amended additional ordinances subsequently
passed.
Procedures for approving plan modifications. Requests for modifications
in the final approved stormwater management controls shall be submitted
to the Borough Engineer as follows:
A.
If the request is initiated before construction begins, the stormwater
plan must be resubmitted and reviewed according to the original procedures.
B.
If the request is initiated after construction is underway, the Borough
Engineer shall have the authority to approve or disapprove the modification,
based on field inspection, provided that the request changes in stormwater
controls do not result in any modifications to other approved borough
land use/development requirements. The Borough Engineer shall maintain
a record of all changes approved for the stormwater management controls
and shall submit these to Borough Council with the final as-built
plans for the development, prior to the acceptance of any improvements
by the Borough and/or the release of any bond money for improvements
being constructed. If no bond money was required, this information
must be submitted prior to the Borough's final inspection of
the plan is completed and approval is granted.
