A.
Pre-application meeting. Prior to proceeding with SWM site plan preparation
and submission, the applicant is encouraged to request a pre-application
meeting with Straban Township to discuss the plan concept and responsibility
for submission of required documents and information. If the project
requires an E&S plan or an NPDES permit, the applicant is encouraged
to meet with a staff member of the Adams County Conservation District
as well.
B.
SWM site plan review and approval procedure.
(1)
If a SWM site plan is not submitted as a component of a subdivision and/or land development plan, the review of the SWM site plan, recommendations, approval, approval with conditions, or disapproval by the Township or its delegate shall occur within 45 calendar days of submission to the Township. Where the applicant submits revisions to a previously submitted SWM site plan, either because the applicant has elected to revise the SWM site plan or as a result of a determination by the Township that a revision is necessary to meet the requirements of this chapter, this forty-five-day period shall be restarted. Should the Township or its delegate fail to render a decision on the SWM site plan within this forty-five-day time period, the application shall be deemed denied. The applicant may appeal the denial pursuant to § 109-41 of this chapter, or may seek an extension of the time for review of the application for consultation with the Township to modify the application.
(2)
If a SWM site plan is submitted as a component of a subdivision and/or
land development plan, the SWM site plan shall be reviewed in accordance
with the review process and time frame established in the Township's
Subdivision and Land Development Ordinance[1] and in accordance with Section 508 of the Pennsylvania Municipalities Planning Code. If the plan is submitted independently of any subdivision and/or land development plan, the review procedures for subdivision and/or land development plans shall be followed as closely as practicable. (See Subsection B(1), above, concerning "deemed denial.")
(3)
NPDES permit technical coordination. Where the project for which
a SWM site plan is submitted is subject to NPDES permitting, the Township
shall notify the Adams County Conservation District when the applicant
has achieved technical compliance with the requirements of this chapter
with respect to SWM site plan requirements. The Township may address
this requirement though the completion of the Technical Review Checklist
for NPDES Sites or comparable process as determined by the Township.
(4)
NPDES permits and E&S plans. Where the project for which a SWM
site plan is submitted is subject to NPDES permitting or the submission
of an E&S plan, or both, any final approval of the SWM site plan
by Straban Township shall be conditioned on the applicant's receipt
of the required NPDES permit or E&S plan approval, as appropriate.
(5)
Approvals from regulating agencies. All appropriate approvals from
regulating agencies including, but not limited to, the Pennsylvania
Department of Transportation, Pennsylvania Department of Environmental
Protection, Adams County Conservation District, and/or the United
States Army Corps of Engineers, with regards to storm drainage and
stormwater management, shall be followed, and evidence of approvals
by those agencies shall be submitted to the Township.
(6)
Decision notification procedure. In all cases, the decision of the Township to approve with conditions, or to disapprove the SWM site plan is to be in writing and delivered to the applicant within 15 calendar days following the decision. If the SWM site plan is disapproved, the written decision by the Township shall state the defects in the application and cite the provisions of the ordinance involved. If the SWM site plan is approved with conditions, the notification to the applicant shall state the acceptable conditions for approval and the time limit for satisfying such conditions. Should the Township fail to notify the applicant of the decision within this fifteen-calendar-day period, the application shall be deemed denied for any and all of the comments stated in any review letter provided to the Township by the Township Engineer, the Township Planning Commission, the County Planning Agency, and/or the Adams County Conservation District and the applicant shall have the right to appeal that denial pursuant to § 109-41 of this chapter.
C.
Waiver requests.
(1)
If a SWM site plan is not submitted as a component of a subdivision
and/or land development plan, the Township may accept a request for
waiver of one or more of the requirements of this chapter. Any such
waiver requests shall comply with the following requirements.
(a)
The Township may accept a request for waiver of the requirements
of one or more provisions of this chapter if the literal enforcement
will enact undue hardship because of peculiar conditions pertaining
to the land in question, provided that the Township determines that
such waiver will not be contrary to the public interest and that the
purpose and intent of the ordinance is observed.
(b)
All requests for waivers from an applicant shall be in writing
and shall accompany and be a part of the application for approval
of a SWM site plan. The request shall state in full the grounds and
facts of unreasonableness or hardship on which the request is based,
the provision or provisions of the ordinance involved, and the minimum
waiver necessary to afford relief.
(c)
The Township shall act to accept or reject requests for waivers within the context of its SWM site plan decisionmaking process established in § 109-26B(1) of this chapter. The decision of the Township regarding acceptance of each request for waiver shall be noted in the minutes of the public meeting of the Township at which acceptance was granted, and notes of the waivers shall be placed on the final copy of the plan.
(2)
If a SWM site plan is submitted as a component of a subdivision and
land development plan, requests for waiver to obtain relief from one
or more of the requirements of this chapter shall be handled in accordance
with the modification process established in the Township's Subdivision
and Land Development Ordinance[2] and Section 512.1 of the Pennsylvania Municipalities Planning
Code, as amended.
A.
SWM site plan not submitted as a component of a subdivision and/or
land development plan. Revisions to a previously approved SWM site
plan to incorporate a change in SWM BMPs or techniques, or the relocation
or redesign of SWM BMPs, or different information about soil or other
conditions from what was stated in the SWM site plan, shall be submitted
by the applicant to the Township. The Township in its sole discretion
may require a resubmission and full review of the revised SWM site
plan in accordance with this chapter, including applicable review
fees. For NPDES permitted sites, any revised SWM site plan shall be
resubmitted to the Adams County Conservation District for its review.
In the case of a SWM site plan which contains minor deficiencies (such
as a missing label, omission of a required note or minor construction
detail), the Township may in its sole discretion accept a resubmission
of such SWM site plan without the requirement of a full review fee,
or a lesser fee.
B.
SWM site plan submitted as a component of a subdivision and/or land
development plan. A revision of an SWM site plan approved as a component
of a subdivision and/or land development plan shall be treated as
a revision of the subdivision and/or land development plan and shall
be subject to the review process established in the Township's
Subdivision and Land Development Ordinance.
A.
SWM site plan not submitted as a component of a subdivision and/or land development plan. A previously disapproved or deemed denied SWM site plan may be resubmitted with the revisions addressing all of the defects of the original submission. The resubmitted SWM site plan shall be reviewed and acted upon in accordance with § 109-26B(1) of this chapter. The applicable review fee must accompany the submission of a revised SWM site plan, unless such fee is waived by the Township.
B.
SWM site plan submitted as a component of a subdivision and/or land
development plan. The resubmission of the SWM site plan originally
submitted as a component of a subdivision and/or land development
plan shall be treated as resubmission of said subdivision and/or land
development plan and shall be subject to the review process established
in the Township's Subdivision and Land Development Ordinance.[1]
A.
SWM site plans not submitted as a component of a subdivision and/or land development plan. The Township's approval of a SWM site plan, when such plan is not submitted as a component of a subdivision and/or land development plan, authorizes the regulated activities contained in the SWM site plan for a maximum term of five years following the date of approval. The Township may specify a term shorter than five years in the decision notification for any specific SWM site plan if the nature of the proposed SWM facilities requires more frequent maintenance (more than annual) and/or short-term replacement of certain components. Terms of authority for the regulated activities shall commence on the date the Township votes to approve the SWM site plan. If an approved SWM site plan is not completed according to § 109-30 within the authorized term, and if a request to extend the permit has not been submitted to the Township by the applicant, the authority terminates and the Township may revoke any and all permits applicable to the project. SWM site plans for projects with expired permits may be resubmitted in accordance with § 109-28 of this chapter.
B.
SWM site plans submitted as a component of a subdivision and/or land
development plan. The term of authority for regulated activities for
a SWM site plan as a component of a subdivision and/or land development
plan shall be in accord with the law governing such plans.
A.
Prior to commencing construction of stormwater management facilities,
the applicant or its agent shall contact the Township's Engineer
a minimum of seven days prior to the start of construction to determine
at which stages of construction the facilities shall be inspected.
No facilities or portion thereof shall be constructed, buried, or
otherwise permanently covered unless and until the inspection of that
stage, as determined by the Township Engineer, has been performed
and that stage of construction has been approved.
B.
During inspections, if it is found that the soil or other conditions
are not as stated or shown in the application and plans approved,
the Township may refuse to approve further work and revoke any or
all permits and/or agreements until approval is obtained for a revised
soil erosion and sedimentation control plan conforming to existing
conditions.
C.
If, at any stage of the work, the Township shall determine by inspection
that the nature of the work is such that further work as authorized
by an existing permit is likely to endanger property or streets or
create hazardous conditions, the Township may require as a condition
to allowing the work to be done that such reasonable safety precautions
be taken as the Township considers advisable to avoid such likelihood
of danger.
D.
No person shall interfere with or obstruct the ingress or egress
to or from any such site or premises by an authorized representative
or agent of the Township of Straban engaged in the inspection of work
for compliance with the approved plans.
E.
The stormwater management facilities constructed in accordance with
a SWM site plan not submitted as a component of a subdivision and/or
land development plan shall be subject to the following process upon
the completion of construction of said facilities.
(1)
The property owner or developer shall contact the Township within
seven days of the completion of the construction process to schedule
a final inspection. The final inspection shall be conducted by the
Township Engineer or such other person designated by the Township.
(2)
The Township may inspect the completed improvements to confirm consistency
with the approved SWM site plan. Following the inspection, if any,
the Township may take one of the following two actions.
(a)
Issue a completion certificate. A completion certificate may
be issued when the Township determines that the stormwater management
facilities have been constructed in conformance with the approved
SWM site plan.
(b)
Issue correspondence regarding discrepancies. If the Township
determines that the stormwater management facilities have not been
constructed in accordance with the approved SWM site plan, it shall
issue correspondence addressed to the property owner or developer
summarizing the discrepancies from the approved SWM site plan. Such
correspondence does not by itself constitute an extension of any applicable
SWM permit.
(3)
Upon receipt of correspondence summarizing discrepancies in the constructed
stormwater facilities, the property owner or developer shall apply
for permit extensions when necessary, and take one of the following
two actions.
(a)
Reconstruct the required stormwater management facilities in a manner that complies with the approved SWM site plan. Prior to commencement of the reconstruction work, the property owner or developer shall contact the municipality for an inspection schedule in accordance with the process established in § 109-30A.
(b)
Submit a revised SWM site plan in accordance with the process established in § 109-27A. The revised SWM site plan shall be consistent with the improvements as constructed. Upon receipt, the Township may review the revised SWM site plan in accordance with the review and approval process of § 109-26. If the revised SWM site plan is approved, the Township shall issue the completion certificate. If the revised SWM site plan fails to demonstrate that the constructed stormwater management facilities can comply with the requirements of this chapter, the Township may then require the property owner or developer to reconstruct the required stormwater facilities in accordance with the originally approved SWM site plan. If the revised SWM site plan is approved, the Township shall then issue the completion certificate.
(4)
Within 15 days of the completion certificate, the property owner
or developer shall submit to the Township an as-built plan depicting
the stormwater management facilities as constructed. If requested
by the applicant, the Township may grant an extension of the deadline
to submit as-built plans.
F.
The stormwater management facilities constructed in accordance with
a SWM site plan submitted as a component of a subdivision and/or land
development plan shall be subject to the completion of improvements
requirements of the Township's Subdivision and Land Development
Ordinance[1] and Sections 509 through 511 of the Pennsylvania Municipalities
Planning Code, as amended.
