Prior to the final approval of subdivision and/or land development plans, the issuance of any permit or the commencement of any land disturbance activity involving any of the regulated activities of this chapter, the owner, subdivider, developer or his or her agent shall submit a drainage plan to the township for approval. The plan shall meet the requirements set forth herein and shall also meet all requirements of Title 25, Rules and Regulations of PADER, Chapter 102, Erosion Control, Chapter 105, Dam Safety and Waterway Management, and Chapter 106, Flood Plain Management.
This section includes activities which may be requested for exemption from the plan preparation provisions of this chapter. Exemptions will be considered and granted by the township on a case-by-case basis. However, activities granted exemption from the plan preparation provisions must still manage stormwater in the manner specified in the other provisions of this chapter.
A.
Residential land disturbance exclusions. Any land disturbance associated with an existing or proposed single, residential, family dwelling to be used as the developer's residence or with land used for gardening for home consumption is exempt from the drainage plan preparation provisions of this chapter.
B.
Agricultural operations exclusion. Any land disturbance associated with agricultural activities operated in accordance with a conservation plan or erosion and sedimentation control plan prepared by the Conservation District is exempt from the drainage plan preparation provisions of this chapter.
C.
Forest management operations exclusion. Any land disturbance associated with forest management operations which is following PADER's management practices contained in its publication "Soil Erosion and Sedimentation Control Guidelines for Forestry" and is operating under an adequate erosion and sedimentation control plan and forest management plan is exempt from the drainage plan preparation provisions of this chapter.
D.
Minor land disturbance activities exemption.
(1)
Any land disturbance activity which involves the disturbance of not more than 1/2 acre of area and which is not otherwise controlled as a regulated activity defined in § 91-4 of this chapter shall be exempt from the drainage plan preparation provisions and permit requirements of this chapter. However, any land disturbance activity, regardless of size, which is undertaken within 50 feet of any stream or water body or where the slope of the disturbed area exceeds 15% shall not be exempt from any of the requirements of this chapter unless otherwise exempted by the provisions of Subsection A, B or C of this section of this chapter.
(2)
In addition, if the minor land disturbance is a portion of a larger activity or is the first phase of a longer-term project or activity, said land disturbance shall not be exempt.
The following items, where appropriate, shall be included in the drainage plan:
