Access easements shall be provided around all stormwater management
facilities serving multiple properties to provide ingress to and egress
from a public right-of-way. Access easements shall have a minimum

Four copies of the SWM site plan shall be submitted as follows:
A.
SWM site plans shall be reviewed by the Borough for consistency with
the provisions of this chapter.
B.
The Borough 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 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.
C.
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.
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 Borough shall require a resubmission of the modified SWM site
plan in accordance with this article.
A disapproved SWM site plan may be resubmitted, with the revisions
addressing the Borough's concerns, to the Borough in accordance
with this article. The applicable review fee 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 § 136-26 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 § 136-24 of this chapter.
A.
The developer shall be responsible for providing as-built plans of
all SWM BMPs included in the approved SWM site plan. The as-built
plans and an explanation of any discrepancies with the construction
plans shall be submitted to the Borough.
B.
The as-built 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
and their outfalls must also be submitted. If any licensed qualified
professionals contributed to the construction plans, then a licensed
qualified professional must sign the completion certificate.
C.
After receipt of the completion certification by the Borough, the
Borough may conduct a final inspection.
