For any of the activities regulated by this chapter, the final
approval of subdivision and/or land development plans, the issuance
of any building or occupancy permit, or the commencement of any land
disturbance activity may not proceed until the property owner or developer

how the facilities are meant to function with each other to manage
stormwater runoff.
For the purpose of complying with this chapter, the steps below
shall be followed for stormwater management site plan submission.
For any activities that require a PA DEP joint permit application
and regulated under Chapter 105 (Dam Safety and Waterway Management)
or Chapter 106 (Floodplain Management) of PA DEP's Rules and
Regulations, require a PA DOT Highway Occupancy Permit, require approval
from the Army Corps of Engineers, or require any other permit under
applicable state or federal regulations, the permit(s) shall be part
of the plan.
A.
The stormwater management site plan shall be submitted by the developer
as part of the preliminary plan submission.
B.
A minimum of three copies of the stormwater management site plan
shall be submitted.
C.
Distribution of the stormwater management site plan will be as follows:
(1)
Two copies to the Borough accompanied by the requisite municipal
review fee, as specified in this chapter.
(2)
One copy to the Municipal Engineer, qualified professional, or agency
designated by the Borough or per municipal ordinance required to review
preliminary and final subdivision or land development plans.
A.
The Borough shall designate the Municipal Engineer or other qualified persons to review the stormwater management site plan for consistency with the adopted Jim Thorpe Borough Watershed Act 167 Stormwater Management Plan. The Borough shall require receipt of a complete plan, as specified in § 377-17 of this chapter.
B.
The Municipal Engineer or other qualified persons designated by the
Borough shall review the stormwater management site plan for any submission
or land development against the Municipal Subdivision and Land Development
Ordinance provisions not superseded by this chapter.
C.
For activities regulated by this chapter, the Municipal Engineer
or other qualified persons designated by the Borough shall notify
the Borough in writing, within 45 calendar days, whether the stormwater
management site plan is consistent with the municipal ordinance and
the Jim Thorpe Borough stormwater management plan. Should the stormwater
management site plan be determined to be consistent with all the above
ordinances and plans, the Municipal Engineer or other qualified persons
designated by the Borough will forward an approval letter to the developer
with a copy to the Municipal Secretary.
D.
Should the stormwater management site plan be determined to be inconsistent
with the municipal ordinance or the Jim Thorpe Borough Stormwater
Management Plan, the reviewer will forward a disapproval letter to
the developer with a copy to the Municipal Secretary citing the reason(s)
for the disapproval. Any disapproved stormwater management site plans
may be revised by the developer and resubmitted consistent with this
chapter.
E.
For activities specified in § 377-4 of this chapter, the reviewer shall notify the Municipal Building Permit Officer in writing, within a time frame consistent with the municipal building code and/or municipal subdivision ordinance, whether the stormwater management site plan is consistent with the municipal ordinance or the Jim Thorpe Borough stormwater management plan and forward a copy of the approval/disapproval letter to the developer. Any disapproved stormwater management site plan may be revised by the developer and resubmitted consistent with this chapter.
F.
For activities requiring a PA DEP joint permit application, the reviewer
shall notify PA DEP whether the stormwater management site plan is
consistent with the Jim Thorpe Borough stormwater management plan
and forward a copy of the review letter to the Borough and the developer.
PA DEP may consider the reviewer's comments in determining whether
to issue a permit.
G.
The Borough shall not approve any subdivision or land development for activities specified in § 377-4 of this chapter if the stormwater management site plan has been found to be inconsistent with Jim Thorpe Borough Stormwater Management Plan, as determined by the Municipal Engineer or other qualified persons designated by the Borough. All required permits from PA DEP must be obtained prior to approval.
H.
The municipal Building Permit Office shall not issue a building permit for any activity specified in § 377-4 of this chapter if the stormwater management site plan has been found to be inconsistent with the Jim Thorpe Borough stormwater management plan, as determined by the Municipal Engineer or other qualified persons designated by the Borough or without considering the comments of the reviewer. All required permits from PA DEP must be obtained prior to issuance of a building permit.
I.
The developer shall be responsible for completing an as-built survey
of all stormwater management facilities included in the approved stormwater
management site plan. The as-built survey and an explanation of any
discrepancies with the design plans shall be submitted to the Municipal
Engineer or other appointed review agency/person for final approval.
In no case shall the Borough approve the as-built survey until the
Borough receives a copy of an approved declaration of adequacy, highway
occupancy permit from the PA DOT District Office, and any applicable
permits from PA DEP.
J.
The Borough's approval of a stormwater management site plan shall be valid for a period not to exceed two years. This two-year time period shall commence on the date that the Borough signs the approved stormwater management site plan. If stormwater management facilities included in the approved stormwater management site plan have not been constructed, or if an as-built survey of these facilities has not been approved within this two-year time period, then the Borough may consider the stormwater management site plan disapproved and may revoke any and all permits. Stormwater management site plans that are considered disapproved by the Borough shall be resubmitted in accordance with § 377-20 of this chapter.
A.
A modification to a submitted stormwater management site plan for a development site that involves a change in stormwater management facilities or techniques, or that involves the relocation or redesign of stormwater management facilities, or that is necessary because soil or other conditions are not as stated on the stormwater management site plan as determined by the Borough, shall require a resubmission of the modified stormwater management site plan consistent with § 377-18 of this chapter and be subject to review as specified in § 377-19 of this chapter.
B.
A modification to an already approved or disapproved stormwater management
site plan shall be submitted to the Borough, accompanied by the applicable
review. A modification to a stormwater management site plan for which
a formal action has not been taken by the Borough shall be submitted
to the Borough, accompanied by the applicable Borough review fee.
A disapproved stormwater management site plan may be resubmitted, with the revisions addressing the reviewer's concerns documented in writing, to the reviewer in accordance with § 377-18 of this chapter and be subject to review as specified in § 377-19 of this chapter. The applicable municipal review fee must accompany a resubmission of a disapproved stormwater management site plan.
