When reviewing a SWM site plan, whether or not the SWM site plan is included in a subdivision and/or land development plan application, the Township's governing body may, after consulting with DEP as noted in § 113-12C of this chapter, grant a modification 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 such modification will not be contrary to the public interest and that the purpose and intent of the chapter is observed.
All requests for a modification from an applicant shall be in writing and shall accompany and be a part of the application for approval of a SWM site plan and/or a subdivision or land development plan as applicable. 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 modification necessary.
In granting of any modification, the Township may attach such reasonable conditions and safeguards as it may deem necessary to implement the purposes of the Act 167 Plan and this chapter.
The governing body of the Township shall keep a written record of all action on requests for modifications. The response of any consultation and/or review by DEP shall be included as an original report if available or otherwise documented in the required written record.
SWM site plan review and approval procedure.
If a SWM site plan does not involve a subdivision and/or land development, the review of the SWM site, recommendations, approval, approval with conditions, or disapproval, i.e., the review and decision period, shall occur within 45 days of submission to the Township. However, the Township, in its sole discretion, may extend the review and decision period another 45 days due to the nature of the application and/or site conditions. If an extension of another 45 days is imposed or granted by the Township beyond the first forty-five-day review and decision period designated by this subsection, the Township shall notify the applicant in writing and deliver such notice to said applicant within 15 days of the decision to extend the review and decision period by the Township. If no extension is imposed or granted by the Township beyond the first forty-five-day review and decision period, and no decision has been rendered by the Township within that period, the SWM site plan shall be deemed approved. Similarly, if after a forty-five-day extension of the review and decision period has been imposed or granted by the Township, and no decision has been rendered by the Township within that period, the SWM site plan shall be deemed approved.
If a SWM site plan involves a subdivision and/or land development plan, the period of time from the submission to the Township of the subdivision and/or land development plan application which includes the SWM plan and the approval, approval with conditions, or disapproval, i.e., review and decision period, shall be 90 days, in accordance with the procedure for approval of plats in Section 508 of the Pennsylvania Municipalities Planning Code.
From the time an application for approval of a plat involving a subdivision or land development plan, whether preliminary or final, which includes a SWM site plan, is duly filed with the Township, no change or amendment of this chapter or other governing ordinance or plan shall affect the decision on such application in accordance with the provisions of the governing ordinances or plans as they stood at the time the application was duly filed, as specified in Section 508(4)(I), of the Pennsylvania Municipalities Planning Code.
Decision notification procedure. In all cases, the decision of the Township to approve or disapprove the SWM site plan shall be in writing and shall be delivered to the applicant no later than 15 days following the decision. If the SWM site plan is disapproved, the written decision by the Township shall specify the defects in the application, describe the requirements which were not met, and shall cite the provisions of the ordinance relied upon. 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. The time limit for satisfying conditions of approval shall be the time limit prescribed for conditional approval of subdivision and land development plans as stated in the Township's Subdivision and Land Development Ordinance.
A revision to a previously submitted SWM site plan that involves a change in SWM BMPs, stormwater management facilities, or changes in analytical techniques, or that involves the relocation or redesign of SWM BMPs, or that is necessary because soil or other conditions are not as stated on the SWM site plan, as determined by the Township, shall require a resubmission of the revised SWM site plan in accordance with this article, including applicable fees. For NPDES permitted sites, any revised SWM site plan shall also be resubmitted to the York County Conservation District for 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, as determined by the Township, the Township may accept a resubmission of such SWM site plan without the requirement of a review fee, or for a lesser fee as provided for in the Township fee schedule.
A disapproved SWM site plan may be resubmitted, with the revisions addressing the Township's concerns as stated regarding the original submission, to the Township in accordance with this article. The applicable review fee must accompany the submission of a revised SWM site plan, unless such fee is waived by the Township. (See § 113-21.)
SWM site plans independent of subdivision and land development plans. The Township's approval of a SWM site plan, when such plan is submitted independent of a subdivision and/or land development plan, authorizes the regulated activities contained in the SWM site plan for a maximum term of validity of five years following the date of approval. The Township may, in its sole discretion, specify a term of validity shorter than five years in the approval for any specific SWM site plan, particularly if the nature of the proposed SWM facilities require more frequent maintenance and/or short-term replacement of certain components. Terms of validity shall commence on the date the Township signs the approval for an SWM site plan. If an approved SWM site plan is not completed according to § 113-24 within the term of validity, then the Township may consider the SWM site plan disapproved and may revoke any and all permits. SWM site plans that are considered disapproved by the Township may be resubmitted in accordance with § 113-22 of this chapter.
SWM site plans included in a subdivision and/or land development plan. The Township's approval of a SWM site plan, which is a part of a subdivision and/or land development plan, authorizes that plan and the regulated activities therein so that no subsequent change or amendment in this chapter or other governing ordinances or plans shall be applied to affect adversely the right of the applicant to commence and to complete any aspect of the approved development in accordance with the terms of such approval within five years from such approval, as specified in Section 508(4)(ii) to (vii) of the Pennsylvania Municipalities Planning Code.
The Township Engineer or his municipal assignee shall inspect phases of the installation of the permanent stormwater management facilities as deemed appropriate by the Township Engineer.
During any stage of the work, if the Township Engineer determines that the permanent stormwater management facilities are not being installed in accordance with the approved stormwater management plan, the Township shall revoke any existing permits until a revised drainage plan is submitted and approved, as specified in this chapter.
The developer shall be responsible for providing as-built plans of all SWM BMPs included in the approved SWM site plan. The as-built plans and an explanation of any discrepancies with the construction plans shall be submitted to the Township. In addition, the as-built plan submission shall include a rerouting of detention basins based on the as-built conditions.
The as-built submission shall include a certification of completion signed by a qualified person verifying that all permanent SWM BMPs have been constructed according to the approved plans and specifications. If any licensed qualified person contributed to the construction plans, then a licensed qualified person must sign the completion certificate.
After receipt of the completion certification by the Township, the Township may conduct a final inspection to verify compliance with, and accuracy of, the as-built plans.
