When it is deemed necessary by the city to install conveyance lines larger than are required to serve adjacent properties, the city may, pursuant to a written agreement between the city and the developer negotiated in advance to any work, compensate the developer for the difference in cost of the oversizing, if the extension is economically feasible for the city. (Ord. 5853 § 1, 2004; Ord. 5212 § 1 (Exh. J), 1999; Ord. 4492 § 4, 1991.)
