§ 19-407 Resubmission of Disapproved Drainage Plans.
For any of the activities regulated by this chapter, the preliminary or 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 applicant or his/her agent has received written approval of a drainage plan from the Shillington Borough Council, unless the project qualifies for an exemption from the requirements to submit a drainage plan.
General Exemptions. The following land use activities are exempt from the drainage plan submission requirements of this chapter.
Use of land for gardening for home consumption.
Agricultural plowing and tilling are exempt from the rate control and SWM site plan preparation requirements of this chapter, provided the activities are performed according to the requirements of 25 Pa. Code, Chapter 102.
Forest management and timber operations are exempt from the rate control and SWM site plan preparation requirements of this chapter, provided the activities are performed according to the requirements of 25 Pa. Code, Chapter 102.
Any regulated activity that meets the impervious area exemption criteria in Table 402-1 shall not be required to implement the stormwater quantity controls, specified in § 19-308 of this chapter. These criteria shall apply to the total development even if development is to take place in phases. The date of the municipal ordinance 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. Impervious areas existing on the "parent tract" prior to adoption of this chapter shall not be considered in cumulative impervious area calculations for exemption purposes.
Submissions for projects that utilize the exemption under Subsection 2A shall still be required to meet the groundwater recharge (§ 19-305), water quality (§ 19-306), and streambank erosion (§ 19-307) controls of this chapter. Drainage plans in accordance with § 19-403, Subsection 2A(2), B(7), (8), (11), (15), and (22), and D(2), must still be submitted. Any exemption must first be approved by the Shillington Borough Council.
Exemption responsibilities. An exemption shall not relieve the applicant from implementing such measures as are necessary to protect the public health, safety, and property. An exemption shall not relieve the applicant from providing adequate stormwater management for regulated activities to meet the requirements of this chapter.
HQ and EV Streams. This exemption shall not relieve the applicant from meeting the special requirements for watersheds draining to high-quality (HQ) or exceptional-value (EV) waters, identified and source water protection areas (SWPA) and requirements for nonstructural project design sequencing (§ 19-304), groundwater recharge (§ 19-305), water quality (§ 19-306), and streambank erosion (§ 19-307).
If a drainage problem is documented or known to exist downstream of, or expected from, the proposed activity, then the Borough of Shillington may require a drainage plan submittal.
