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.
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. These criteria shall apply to the total development even if development is to take place in phases. The date of the municipal ordinance adoption by the county shall be the starting point from which to consider tracts as parent tracts in which future subdivisions and respective impervious area computations shall be cumulatively considered. Exemption shall not relieve the applicant from providing adequate stormwater management to meet the purpose 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.
The drainage plan shall be submitted by the developer to the municipality as part of the preliminary plan submission for the regulated activity.
Six copies of the drainage plan shall be submitted. distribution of the drainage plan will be as follows:
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.
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for any submission or land development against the municipal subdivision and land development ordinance provisions not superseded by this article.
The County Conservation District shall review and approve the E & S plan for consistency with PADEP's Chapter 102 regulations.
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.
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.
The developer shall be responsible for completing an as-built survey of all stormwater management facilities included in the approved drainage plan. The as-built survey and an explanation of any discrepancies with the design plans shall be submitted to the municipality for final approval.
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 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.

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.
