When an applicant is required by the City to construct an oversized sewer line, the City may pay directly to the installing applicant or developer the cost of oversizing. Such payment will be made from connection fees received by the City for lateral connections to the sewer, including connection fees of the applicant. Only sewers larger than six inches (6") internal diameter shall be considered oversized, however, if the new development requires a sewer line larger than six inches (6") for its own purposes, then oversizing will be considered to be a size requirement larger than that needed to serve the development. The Public Works Director is empowered to make the determination as to how much, if any, oversizing is required and is also empowered to determine the difference in cost between the actual installation and the average cost of a six inch (6") (or larger) sewer line. The finding of the Public Works Director shall be conclusive. (Ord. 395 N.S., 6-6-1983, eff. 7-1-1983)
