For any of the activities regulated by this
article, the final approval of subdivision and/or land development
plans, the issuance of any building or occupancy permit, or the commencement
of any earth disturbance activity may not proceed until the property
owner or developer or his/her agent has received written approval
of a drainage plan from the municipality.
A.
Any regulated activity described in § 124-70 of this article that is less than or equal to 5,000 square feet of impervious area is exempt from the drainage plan preparation provisions of this article.

For all regulated activities listed in § 124-70 of this article, the steps below shall be followed for submission. For any activities that require a PADEP joint permit application and regulated under Chapter 105 (Dam Safety and Waterway Management) or Chapter 106 (Floodplain Management) of PADEP's rules and regulations, require a PADOT highway occupancy permit, or require an NPDES permit for stormwater discharge from construction sites or require any other permit under applicable state or federal regulations, the permit(s) shall be part of the drainage plan.
A.
The municipality shall review the drainage plan for
consistency with the adopted Tobyhanna Creek Watershed Act 167 Stormwater
Management Plan. The municipality shall require receipt of a complete
plan, as specified in this article.
B.
The municipality shall review the drainage plan for
any submission or land development against the municipal subdivision
and land development ordinance provisions not superseded by this article.
C.
The County Conservation District shall review and
approve the E & S plan for consistency with PADEP's Chapter 102
regulations.
D.
For activities regulated by this article, the Municipal
Engineer shall notify the municipality in writing, within 30 calendar
days, whether the drainage plan is consistent with the stormwater
management plan. Should the drainage plan be determined to be consistent
with the stormwater management plan, the municipality will forward
an approval letter to the developer. Should the drainage plan be determined
to be inconsistent with the stormwater management plan, the Municipal
Engineer will forward a disapproval letter to the municipal secretary
and developer citing the reason(s) for the disapproval. Any disapproved
drainage plans may be revised by the developer and resubmitted consistent
with this article.
E.
The municipality shall not approve any subdivision or land development for regulated activities specified in § 124-70A and B of this article or issue a building permit if the drainage plan has been found to be inconsistent with the stormwater management plan, as determined by the municipality, or without considering the comments of the Municipal Engineer. All required permits from PADEP must be obtained prior to approval.

of any discrepancies with the design plans shall be submitted to the
municipality for final approval.
G.
The municipality's approval of a drainage plan shall be valid for a period not to exceed one year. This one-year time period shall commence on the date that the municipality signs the approved drainage plan. If stormwater management facilities included in the approved drainage plan have not been constructed, or if an as-built survey of these facilities has not been approved within this one-year time period, then the municipality may consider the drainage plan disapproved and may recommend that the municipality revoke any and all permits. drainage plans that are considered disapproved by the municipality may be resubmitted in accordance with § 124-90 of this article.
A.
A modification to a submitted drainage 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 E & S controls, or that is necessary because soil or other conditions are not as stated on the drainage plan (as determined by the municipality or the Municipal Engineer), shall require a resubmission of the modified drainage plan consistent with § 124-87 of this article and be subject to review as specified in § 124-88 of this article.

municipality review fee.
A disapproved drainage plan may be resubmitted, with the revisions addressing the municipality's concerns documented in writing, to the municipality in accordance with § 124-87 of this article and be subject to review as specified in § 124-88 of this article. The applicable municipality review fee must accompany a resubmission of a disapproved drainage plan.
