This storm sewer system shall be designed to carry the anticipated runoff for a twenty-five-year, five-minute storm event as per the current edition of the Pennsylvania Department of Transportation Design Manual, Part 4, for the watershed in a fully developed condition.
F. 
Unnatural drainage. Natural drainage patterns shall not be changed by concentrating the drainage patterns or creating additional overland sheet flow onto adjoining properties due to construction. If new drainage patterns are created, the developer shall be responsible for the redirection of the unnatural drainage flow by an approved storm drainage system. Approval of development plans by the Borough does not relieve the developer of the responsibility of creating unnatural drainage patterns that affect adjoining properties.
G. 
Watercourses. Open watercourses shall not be permitted within the rights-of-way of streets. The stopping, filling up, confining or other interference with, or changing the course of, drains, ditches, streams and watercourses in the Borough shall not be permitted unless approval, in writing, is obtained from the Borough Council.

The storm sewer fee shall be in addition to all other costs incurred by the developer in providing necessary storm sewers within the plan submitted for final approval.
(2) 
All storm sewer fees shall be deposited in the storm sewer fund and shall be used for the purposes of providing proper drainage facilities to natural watersheds, to provide for the clearing of obstructions and limitations in existing watersheds and for any and all necessary expenses related to stormwater drainage throughout the Borough of Oakdale.
J. 
Storm sewer cleanouts. A storm sewer cleanout may be utilized at the terminus of storm sewers used for roof drain collection only. A maximum of two structures may discharge into a storm sewer that utilizes a cleanout at the terminus of the storm sewer line. The maximum distance between cleanouts is 150 feet. Cleanouts may not be installed on any storm sewers larger than 10 inches in diameter. The cleanout shall be an SDR 35 PVC or equal pipe a minimum of six inches in diameter. A SDR 35 PVC or equal cap shall be installed on top of the cleanout and shall have a recessed nut head for future maintenance.
K. 
Storm sewer laterals. Lateral connections shall be installed for each roof drain, foundation drain and/or driveway drain for each structure or lot at the public street right-of-way or edge of a proposed easement for each structure prior to paving. The storm sewer laterals shall be connected to a manufactured wye in the main storm sewer line, and a cleanout shall be installed at the right-of-way or edge of the easement upon the completion of the backfilling.
L. 
Storm sewer pipe material. Storm sewer pipes shall be made of corrugated plastic pipe with a smooth interior (ASTM F-405, AASHTO M-252), Class TV reinforced concrete pipe or polyvinyl chloride (PVC) pipe (SDR 35 or thicker, ASTM 3034). A combination of the above pipes may be required on a single land development as required by the Borough Engineer.
M.

Editor's Note: See Attachment 1, Standards of Construction Details, of Ch. 308, Streets and Sidewalks.
N. 
Acceptance. All storm sewers shall be inspected prior to acceptance by the Borough by closed circuit television (CCTV). The video shall be on VHS format at a rate no faster than three per second showing a clear view of the lateral connections. A copy of the CCTV inspection video shall be delivered to the Borough at the time of requesting acceptance of the storm sewer system. The CCTV inspection shall be at the developer's expense, and cost should be included in the bonding requirements. All debris shall be removed from all manholes, inlets, catch basins and cleanouts prior to acceptance, and the cost shall be borne by the developer. All defects shall be repaired, and the cost shall be borne by the developer.
O. 
Tap-in fee.
(1) 
Each lot in a subdivision, whether developed or vacant, will be assessed a storm sewer tap-in fee. Payment of the fee shall be due at the time of execution of the development agreement, or if a development agreement is not required, as a condition precedent to the Borough signing the final plat. Fees shall be based on the fee schedule adopted by the Borough annually.[4] A note shall be shown on the plan for recording indicating this requirement.
