For lots developed where an engineering, grading, and drainage plan has not been prepared and approved pursuant to Title Six of Part Twelve of these Codified Ordinances (the Land Development Regulations), the following minimum requirements shall apply:
(a) An eight-inch enclosed drainage line of materials subject to approval by the Township Engineer shall be constructed along the side and rear property lines. A variance in the size and location of the eight-inch line shall be subject to issuance by the Superintendent of the Department of Public Works upon written application therefor.
(b) A two-foot catch basin or a special basin as approved by the Superintendent of the Department of Public Works shall be placed in approved locations at the intersections of the side and rear property lines.
(c) The drainage line shall be made available to adjacent property owners through extension of the line to abutting property lines. An easement permitting the receipt of drainage and the establishment of a connection shall be provided.
(d) Lots shall be graded to allow water to flow freely to the catch basin.
(e) As determined by the Superintendent of the Department of Public Works, a swale may be required along side lots.
(f) Sump pumps may not discharge to any road surface. Sump pumps may only be directed to a storm sewer or a location in a ditch or swale as approved in writing by the Superintendent of the Department of Public Works.
(g) In the event three or more contiguous lots are being developed, the rear lot storm sewer line shall be constructed of materials as approved by the Township.
(h) In the event a site drainage plan cannot meet the requirements of this section and/or this Building and Housing Code, a variance may be sought in writing from the Superintendent of Water and Sewers, the Superintendent of Public Works, the Township Engineer or their designees. The standards for issuance of a variance shall be the same standards as set forth under the Land Development Regulations (Title Six of Part Twelve of these Codified Ordinances) for the issuance of variances.
