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 or his/her agent has received written approval of a drainage plan from the Plan Administrator.
A. 
Any regulated activity that meets the exception criteria in this chapter's Appendix A[1] is exempt from the drainage plan preparation provisions of this chapter. This criteria shall apply to the total development even if development is to take place in phases. The date of the Official County Plan adoption 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 chapter.

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 PennDOT highway occupancy permit, or require any other permit under applicable state or federal regulations, the permit(s) shall be part of the plan.
A. 
The drainage plan shall be submitted by the developer as part of the preliminary plan submission for the regulated activity.
B. 
Four copies of the drainage plan shall be submitted.
C. 
Distribution of the drainage plan will be as follows:
(1) 
One copy to the City accompanied by the requisite City review fee, as specified in this chapter.
(2) 
One copy to the City Engineers.
(3) 
Two copies to the Plan Administrator accompanied by the requisite Plan Administrator review fee as specified in this chapter.
A. 
The Plan Administrator shall review the drainage plan for consistency with the adopted Sandy Lick Creek Watershed Act 167 Stormwater Management Plan. The Plan Administrator shall require receipt of a complete plan, as specified in this chapter.
B. 
The City Engineer shall review the drainage plan for any submission or land development against the Chapter 390, Subdivision and Land Development, provisions not superseded by this chapter.
C. 
For activities regulated by this chapter, the Plan Administrator shall notify the City, in writing, within 90 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 Plan Administrator will forward an approval letter to the City Manager with a copy to the developer. Should the drainage plan be determined to be inconsistent with the stormwater management plan, the Plan Administrator will forward a disapproval letter to the City 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 chapter.
D. 
For regulated activities specified in § 379-4D(5) and (6) of this chapter, the Plan Administrator shall notify the City Building Permit Officer, in writing within a time frame consistent with the City Building Code, whether the drainage plan is consistent with the stormwater management plan and forward a copy of the approval/disapproval letter to the developer. Any disapproved drainage plan may be revised by the developer and resubmitted consistent with this chapter.
E. 
For regulated activities requiring a PADEP joint permit application, the Plan Administrator shall notify PADEP whether the drainage plan is consistent with the stormwater management plan and forward a copy of the review letter to the City and the developer. PADEP may consider the Plan Administrator's review comments in determining whether to issue a permit.
F. 
The City shall not approve any subdivision or land development for regulated activities specified in § 379-4D(1) and (2) of this chapter if the drainage plan has been found to be inconsistent with the stormwater management plan, as determined by the Plan Administrator, or without considering the comments of the City Engineer. All required permits from PADEP must be obtained prior to approval.
G. 
The City Building Permit Officer shall not issue a building permit for any regulated activity specified in § 379-4 of this chapter if the drainage plan has been found to be inconsistent with the stormwater management plan, as determined by the Plan Administrator, or without considering the comments of the City Engineer. All required permits from PADEP must be obtained prior to issuance of a building permit.
H. 
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 Plan Administrator for final approval. In no case shall the Plan Administrator approve the as-built survey until the Plan Administrator receives a copy of an approved declaration of adequacy, highway occupancy permit from the PennDOT District Office, and any applicable permits from PADEP.
I. 
The Plan Administrator'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 Plan Administrator 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 Plan Administrator may consider the drainage plan disapproved and may recommend that the City revoke any and all permits. Drainage plans that are considered disapproved by the Plan Administrator shall be resubmitted in accordance with § 379-19 of this chapter.
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 that is necessary because soil or other conditions are not as stated on the drainage plan (as determined by the Plan Administrator or the City Engineer), shall require a resubmission of the modified drainage plan consistent with § 379-16 of this chapter and be subject to review as specified in § 379-17 of this chapter.
B. 
A modification to an already approved or disapproved drainage plan shall be submitted to the Plan Administrator, accompanied by the applicable Plan Administrator review fee. A modification to a drainage plan for which a formal action has not been taken by the Plan Administrator shall be submitted to the Plan Administrator, accompanied by the applicable Plan Administrator review fee.
A disapproved drainage plan may be resubmitted, with the revisions addressing the Plan Administrator's concerns documented, in writing, to the Plan Administrator, in accordance with § 379-16 of this chapter and be subject to review as specified in § 379-17 of this chapter. The applicable Plan Administrator review fee must accompany a resubmission of a disapproved drainage plan.
